Duodenoscope ERCP: Overview, Uses and Top Manufacturer Company

Introduction

Duodenoscope ERCP refers to the specialized flexible endoscope (a duodenoscope) used to perform ERCP—Endoscopic Retrograde Cholangiopancreatography—a procedure that accesses the bile ducts and pancreatic duct through the small intestine. In day-to-day hospital operations, this clinical device sits at the intersection of gastroenterology, surgery, anesthesia, radiology (fluoroscopy), sterile processing, and infection prevention.

Why it matters: ERCP can be both diagnostic and therapeutic, and in many institutions it is primarily a therapeutic procedure used to relieve obstruction, drain infection, remove stones, or place stents. That ability to “diagnose and treat in one session” can be operationally valuable, but it also comes with meaningful patient risks and complex device reprocessing requirements. Duodenoscopes are among the most challenging reusable medical equipment items to clean due to intricate moving parts at the distal (tip) end.

A practical way to think about ERCP is as a “duct access and intervention” workflow: access is achieved endoscopically, anatomy is confirmed radiographically, and therapy is delivered through the scope’s working channel. Over time, many healthcare systems have shifted toward using noninvasive imaging for diagnosis and reserving ERCP for therapeutic intent—an evolution that affects training pathways, staffing models, and how hospitals justify capital investment in ERCP suites.

This article explains what Duodenoscope ERCP is, how it works in plain language, and how trainees typically learn it. It also covers practical “before you start” operational needs, basic workflow, safety and monitoring principles, troubleshooting, and infection control concepts. Finally, it provides a globally aware overview of manufacturers, distribution models, and country-level market dynamics—useful for clinicians, biomedical engineers, and procurement and hospital operations leaders.

What is Duodenoscope ERCP and why do we use it?

Clear definition and purpose

A duodenoscope is a flexible, steerable endoscope designed to reach the second portion of the duodenum (the first part of the small intestine) and visualize the major duodenal papilla (also called the ampulla of Vater), where the bile duct and pancreatic duct empty into the bowel. ERCP uses this access point to introduce small accessories (such as guidewires and cannulas) into the ducts, inject contrast under fluoroscopy (real-time X‑ray imaging), and perform therapeutic interventions.

Clinically, ERCP is often described as a combined endoscopic–radiologic procedure. The endoscopic view helps the operator align with the papilla and control accessory movement, while fluoroscopy provides the “map” of ductal anatomy and confirms where wires, balloons, baskets, and stents are positioned. Understanding how these two views complement each other is central to safe and efficient ERCP.

In practice, Duodenoscope ERCP is used to:

• Reach and visualize the papilla with a side-viewing endoscope (most duodenoscopes are side-viewing rather than forward-viewing).
• Cannulate (enter) the bile duct and/or pancreatic duct using a guidewire-assisted technique.
• Perform interventions such as stone extraction, dilation, tissue sampling, and placement or exchange of stents, depending on the clinical scenario and local practice.

Core design features that make a duodenoscope different

While many flexible endoscopes share common elements (camera, light source, working channel), duodenoscopes are purpose-built for duct cannulation and device delivery. Common design concepts include:

• Side-viewing optics: the camera looks sideways rather than straight ahead, making it easier to face the papilla when the scope is “parked” in the duodenum.
• Large working channel (often around the 4 mm range, model-dependent): supports the passage of ERCP accessories such as sphincterotomes, extraction balloons, baskets, and stent delivery systems.
• Elevator mechanism (forceps elevator): a movable lever at the distal tip that changes the angle of accessories exiting the channel, improving control during cannulation and therapy.
• Angulation and torque control optimized for duodenal positioning: stability matters because small scope movements can translate into large changes at the papilla.

From a hospital perspective, these same features that enable therapy also make the device mechanically complex and reprocessing-sensitive, which is why “use” and “care” are inseparable topics for duodenoscopes.

Common clinical settings

Duodenoscope ERCP is typically used in:

• Endoscopy units with fluoroscopy capability (dedicated ERCP suites).
• Operating theatres or hybrid rooms (especially when anesthesia support or surgical backup is required).
• Tertiary referral centers, where complex pancreaticobiliary disease is concentrated.
• Urgent or on-call scenarios, such as suspected biliary obstruction with infection requiring drainage (institutional protocols vary).

Many facilities also perform ERCP for both inpatient and outpatient populations. In some hospitals, ERCP lists are scheduled during the day for elective cases (e.g., planned stone extraction or stent exchange), while separate pathways exist for emergency cases (e.g., acute cholangitis) that may occur after-hours. These operational differences influence which staff are on-call, how accessories are stocked, and how quickly reprocessed scopes must be available.

From an operations perspective, ERCP is a “high coordination” workflow: it requires a trained endoscopy team, fluoroscopy support, reprocessing capacity, and strong equipment readiness practices.

Key benefits in patient care and workflow

Compared with open surgical approaches to the biliary tree, ERCP can offer:

• Minimally invasive access to ducts without an external incision.
• Therapy during the same session as imaging (e.g., drainage and stenting after confirming a blockage).
• Potentially shorter recovery and reduced need for more invasive procedures in selected patients.
• Workflow consolidation, especially when imaging, intervention, and documentation are integrated into the endoscopy/radiology ecosystem.

Additional practical advantages can include avoiding or reducing reliance on external drainage catheters in selected situations, and providing a “bridge” to definitive surgery or oncology therapy by relieving obstruction. However, these benefits are not universal and depend on indication, anatomy, operator experience, and available alternatives (such as magnetic resonance cholangiopancreatography [MRCP] or endoscopic ultrasound [EUS]).

How it functions (plain-language mechanism)

At a high level, Duodenoscope ERCP works like this:

• The duodenoscope is inserted through the mouth and advanced through the esophagus and stomach into the duodenum.
• A camera and light provide a live endoscopic view of the bowel and papilla on a monitor.
• A working channel inside the scope allows accessories to pass from the operator’s hand to the scope tip.
• A small elevator mechanism near the distal tip helps “lift and angle” accessories so they can be directed into the papilla—this is a key differentiator versus many other endoscopes.
• Once a duct is cannulated, contrast can be injected and the duct anatomy is assessed using fluoroscopy.
• Therapeutic accessories are then used through the working channel (for example, balloons, baskets, sphincterotomes, and stents). Accessory choice and technique vary by patient, operator, and manufacturer.

In a typical case, the team repeatedly switches between endoscopic actions (positioning, cannulation, accessory manipulation) and fluoroscopic confirmation (wire position, duct opacification, device deployment). This “two-screen” nature of ERCP is why clear role assignment and communication are so important; for example, one person may manage fluoroscopy while another manages guidewire tension and accessory exchange.

How medical students typically encounter or learn this device in training

Medical students and early trainees often meet Duodenoscope ERCP through:

• Anatomy and physiology teaching (biliary tree, pancreas, sphincters, jaundice, pancreatitis).
• Clinical rotations in gastroenterology, general surgery, hepatobiliary services, or interventional endoscopy, where they may observe ERCP indications and peri-procedural care.
• Team-based workflow exposure, including informed consent discussions (observed), sedation/anesthesia planning, radiation safety practices, and post-procedure monitoring.
• Systems learning, such as understanding how reprocessing, traceability, preventive maintenance, and incident reporting contribute to patient safety with reusable hospital equipment.

Where available, learners may also see ERCP training supported by simulation (mechanical models, animal tissue models, or virtual reality platforms) and structured assessment tools that break the procedure into definable competencies (scope positioning, cannulation technique, fluoroscopic interpretation, and safe therapeutic steps).

For administrators and engineers, the learning curve is different: it centers on serviceability, reprocessing validation, device uptime, and standardization across sites.

When should I use Duodenoscope ERCP (and when should I not)?

Appropriate use cases (general)

Duodenoscope ERCP is generally considered when there is a clinical need to intervene in the biliary or pancreatic ductal system, such as:

• Suspected bile duct obstruction where endoscopic drainage or stenting may be required.
• Suspected bile duct stones when endoscopic removal is anticipated.
• Suspected biliary infection where urgent decompression is part of the care pathway in some settings.
• Bile leaks after surgery or injury, where targeted stenting may support healing.
• Benign or malignant strictures, where dilation and/or stenting may be needed.
• Selected pancreatic duct indications (case selection varies widely by institution and operator expertise).

Additional scenarios that may bring patients to ERCP programs include stent exchange for previously treated strictures, management of recurrent stone disease in high-risk surgical candidates, and targeted sampling of ductal lesions when tissue diagnosis will change management. Importantly, many centers now reserve ERCP primarily for therapeutic intent, using noninvasive imaging (for example, ultrasound, computed tomography, or MRCP) for diagnosis where appropriate.

Situations where it may not be suitable

Duodenoscope ERCP may be less suitable when:

• The goal is diagnosis only and safer noninvasive imaging alternatives can answer the question.
• The patient has altered upper gastrointestinal anatomy that prevents standard duodenoscope access to the papilla (for example, certain post-surgical reconstructions). Alternative approaches may be considered by specialist teams.
• There is a high sedation or anesthesia risk and the expected benefit does not justify the procedural risk.
• Fluoroscopy is unavailable or unsafe in the setting (e.g., infrastructure limitations or specific patient scenarios), and no alternative imaging strategy is feasible.
• Facility-level resources (reprocessing, trained staff, backup support) are insufficient to meet safety standards for this medical device workflow.

Other practical limitations can include an inability to safely position the patient for fluoroscopy due to instability, severe coagulopathy when a cutting intervention is likely and risk mitigation is not feasible, or a lack of immediate rescue capability for complications in a facility that does not have appropriate escalation pathways.

Safety cautions and contraindications (general, non-prescriptive)

Contraindications and cautions depend on the intended intervention and local guidelines, but commonly considered issues include:

• Inability to tolerate endoscopy or sedation/anesthesia.
• Conditions that increase the risk of bleeding for interventions that cut tissue (for example, sphincterotomy), where risk mitigation strategies are required per protocol.
• Suspected or known perforation of the gastrointestinal tract (procedure approach may change).
• Contrast-related concerns (agent selection and precautions are protocol-driven).
• Pregnancy and radiation exposure considerations (risk-benefit decisions are specialist-led and vary by setting).

Because ERCP can cause serious adverse events, it should be performed by appropriately trained clinicians with the required team and facility support. In many institutions, “caution” also includes considering the likelihood that ERCP will succeed (for example, predicted difficulty of cannulation, known strictures, or suspected tumor-related narrowing) and whether alternative or adjunct techniques (such as EUS-guided approaches or percutaneous drainage) are more appropriate in the local context.

Emphasize clinical judgment, supervision, and protocols

For learners: ERCP is not a “see one, do one” procedure. Most training pathways involve structured observation, simulation where available, progressive responsibility, and supervised practice.

For hospitals: the decision to offer Duodenoscope ERCP is also an operational commitment—credentialing standards, reprocessing validation, radiation safety, and incident response processes need to be in place.

What do I need before starting?

Required setup, environment, and accessories

A safe ERCP environment typically includes:

• Duodenoscope system components: duodenoscope, video processor, light source, monitor(s), and recording/documentation tools.
• Fluoroscopy: imaging equipment, radiation shielding, and trained personnel (often radiology technologists), with local radiation safety governance.
• Patient monitoring: physiologic monitors, oxygen supply, suction, and resuscitation equipment appropriate to the sedation/anesthesia model used.
• Accessory ecosystem (varies by case and manufacturer compatibility): guidewires, cannulas, sphincterotomes, extraction balloons/baskets, dilation balloons, stents, contrast injection supplies, and irrigation.
• Electrosurgical generator (if cutting/coagulation is planned), with compatible accessories and grounding/return electrode practices as per local policy.

Many ERCP rooms also rely on practical “support items” that are easy to overlook but crucial for smooth workflow: radiation PPE (lead aprons, thyroid shields, protective eyewear), dosimeters (where used), foot pedals for fluoroscopy or electrosurgery (room layout matters), and a clear plan for contrast handling and labeling.

From a supply chain perspective, ERCP is accessory-intensive. Procurement teams should map which accessories are routinely stocked, which are specialty items, and what is needed for after-hours coverage.

Training and competency expectations

Competency is broader than the endoscopist:

• Endoscopist: technical ERCP skills, fluoroscopy interpretation, complication recognition, and therapeutic decision-making.
• Endoscopy nurses/technicians: room setup, accessory handling, guidewire management, specimen handling, and documentation.
• Anesthesia/sedation team: airway and hemodynamic management per institutional model.
• Sterile processing/reprocessing staff: validated cleaning and high-level disinfection/sterilization workflow adherence.
• Biomedical engineering (clinical engineering): preventive maintenance, safety testing, repair coordination, and post-repair validation.
• Infection prevention and control: auditing, surveillance practices (where used), and response to reprocessing deviations.

Many hospitals also include radiation safety training as a defined competency for ERCP teams, including principles of time, distance, shielding, and collimation, as well as how to document exposure metrics when required.

Hospitals should align competency expectations with credentialing, onboarding, and continuing education practices.

Pre-use checks and documentation

Common pre-use checks (model-specific steps vary) include:

• Verify the scope has completed the facility’s reprocessing cycle and is within any defined “use window” (if applicable).
• Perform a visual inspection for damage (insertion tube, bending section, distal tip, lens, and seals).
• Confirm angulation controls and the elevator mechanism move smoothly and return appropriately.
• Check air/water insufflation and suction function, including valves and connectors.
• Confirm working channel patency by passing an appropriate test accessory (per policy).
• Confirm traceability documentation (scope ID, reprocessing batch/cycle details, user, patient linkage per local rules).

Some facilities also perform a quick “readiness check” of the image chain: ensure the correct scope is recognized by the processor, the image is not degraded (fogging, dead pixels, poor light transmission), and the distal tip has no visible residue or debris. Any concern should trigger a stop-and-escalate decision rather than “hoping it will be fine” once the patient is sedated.

Documentation practices vary by country and facility, but traceability is a recurring safety expectation for reusable medical equipment.

Operational prerequisites: commissioning, maintenance readiness, consumables, and policies

Before a Duodenoscope ERCP service is “real,” hospitals typically need:

• Commissioning/acceptance testing: verify compatibility with processors, image quality, electrical safety checks, integration with documentation systems, and validation of reprocessing workflows.
• Preventive maintenance plan: scheduled inspections, leak tester calibration (if used), performance checks, and defined criteria for “remove from service.”
• Repair and loaner strategy: a plan for downtime, including vendor service turnaround expectations and scope availability during maintenance.
• Consumables readiness: detergents, brushes, disinfectants/sterilants (as used), personal protective equipment (PPE), water quality management, and drying/storage supplies.
• Policies and governance: credentialing, radiation safety, infection control, incident reporting, and product recall/field safety notice workflows.

Operationally, it is also helpful to define how ERCP images and reports will be stored and retrieved (endoscopy reporting system, radiology archive, or both). Clear IT integration reduces delays, supports auditing, and improves continuity of care when patients move between facilities.

Roles and responsibilities (clinician vs. biomedical engineering vs. procurement)

Clear ownership reduces delays and safety gaps:

• Clinicians/endoscopy leadership: define clinical indications, procedural standards, staffing models, and escalation pathways.
• Biomedical engineering: manage asset inventory, preventive maintenance, repairs, post-repair validation, and equipment standardization.
• Procurement/supply chain: contract terms (service, training, loaners), accessories and consumables strategy, and total cost-of-ownership analysis.
• Infection prevention: validate and audit reprocessing processes, investigate deviations, and coordinate response to suspected device-related infection concerns.
• Sterile processing/endoscopy reprocessing: day-to-day reprocessing execution, documentation, and storage practices.

In many hospitals, radiology leadership and IT teams are also stakeholders because fluoroscopy governance, dose reporting, and image storage influence both safety and compliance.

How do I use it correctly (basic operation)?

Workflows vary by model, institution, and clinical scenario. The outline below is a high-level educational overview of commonly shared steps.

Basic step-by-step workflow (typical sequence)

1. Room readiness – Confirm fluoroscopy availability, radiation protection measures, and monitoring equipment. – Verify required accessories are present and compatible with the duodenoscope system. – Ensure the room layout supports safe movement around the C‑arm or fluoroscopy equipment, minimizing trip hazards from cables and foot pedals.

2. Device setup – Connect the duodenoscope to the video processor and light source. – Confirm image quality (often including white balance or color calibration, depending on system). – Attach suction and air/water/insufflation connections per manufacturer guidance. – Confirm that any disposable valves, caps, or water bottles (if used) are correctly installed per policy.

3. Team briefing and time-out – Confirm patient identity, planned procedure, anticipated equipment needs, and escalation plan. – Align roles: primary operator, assistant, nurse/tech managing accessories, fluoroscopy operator, and sedation/anesthesia lead. – Review key safety items such as anticoagulation status (if relevant to the planned intervention), antibiotic strategy (if applicable), and radiation protection expectations.

4. Scope insertion and positioning – Insert the duodenoscope and advance under direct visualization to the duodenum. – Identify the major papilla and optimize scope position for stable access. – Many teams also confirm patient positioning (often prone or semi-prone in some settings, but practice varies) to optimize fluoroscopic views and procedural ergonomics.

5. Cannulation and duct access – Introduce a cannulation device (often with a guidewire) through the working channel. – Use the elevator to direct the accessory tip toward the papilla. – Confirm duct access using fluoroscopy and careful contrast injection per technique and protocol. – Maintain deliberate guidewire control to reduce unintended pancreatic duct instrumentation when biliary access is the goal (strategy depends on local practice and anatomy).

6. Imaging and interpretation – Acquire fluoroscopic images to understand ductal anatomy and the nature of the obstruction or leak. – Adjust patient positioning and scope position as needed to optimize visualization. – Use collimation and pulsed fluoroscopy practices as available to support radiation dose optimization under local policy.

7. Therapeutic intervention (as indicated) – Perform the planned therapy (examples include sphincterotomy, stone extraction, dilation, stent placement, or sampling). – Re-check outcomes (for example, duct drainage, stent position) under fluoroscopy. – Confirm hemostasis endoscopically when a cutting intervention has been performed and document key findings.

8. Procedure completion – Withdraw accessories and the scope safely. – Ensure key images and details are documented and the patient is transferred to recovery with an appropriate handoff. – Communicate clear post-procedure instructions and monitoring priorities to the recovery team (e.g., pain assessment, nausea control, and escalation triggers).

Immediate post-procedure recovery considerations (operational view)

Although post-procedure clinical management is guided by local protocols, operationally consistent recovery practices support safety:

• Confirm the patient’s vital signs and pain level are stable for the expected sedation/anesthesia model used.
• Ensure the clinical team documents what was done (e.g., stent type/size if used, whether sphincterotomy occurred, whether there was difficult cannulation or pancreatic duct instrumentation) because these details influence monitoring and future planning.
• Provide clear instructions for escalation if symptoms suggest complications (for example, worsening abdominal pain, fever, bleeding, or hemodynamic instability), acknowledging that complication profiles and monitoring practices vary by institution.

Setup and “calibration” concepts (where relevant)

ERCP “calibration” is often more about system readiness than numerical calibration:

• Endoscopy image setup: white balance/color calibration and focus checks (system-dependent).
• Fluoroscopy setup: collimation, patient positioning, and radiation dose optimization are typically managed by trained personnel under institutional radiation safety frameworks.
• Electrosurgical generator settings: depend on accessories, technique, and local protocol; settings are not universal and may be defined by the manufacturer’s instructions for use (IFU) and clinical governance.

Some hospitals additionally track fluoroscopy time and/or dose indicators for quality improvement and safety reporting. Where such tracking exists, ensuring accurate documentation is part of “correct use,” not just a clerical task.

Typical settings and what they generally mean (non-brand-specific)

• Insufflation: air or carbon dioxide (CO₂) insufflation may be used; selection is protocol-driven and system-dependent.
• Suction and irrigation: used to maintain a clear field, remove secretions, and flush the working channel.
• Fluoroscopy mode: pulse rate, magnification, and “last image hold” practices can influence image quality and radiation exposure; these settings are managed under local radiology and safety policies.

Common “universal” handling points (regardless of model)

• Avoid forcing accessories through resistance; stop and troubleshoot alignment and elevator position.
• Keep the distal tip under visualization whenever possible to reduce mucosal injury risk.
• Protect the insertion tube from sharp bends and crushing during use and transport.
• Coordinate accessory exchanges with the assistant to avoid guidewire loss or unintended wire movement.
• Treat the duodenoscope as both a delicate optical instrument and a high-risk reusable medical device requiring strict traceability.
• Be deliberate when manipulating accessories with the elevator engaged; uncontrolled movements can damage channels or increase mucosal trauma risk.

How do I keep the patient safe?

Patient safety in Duodenoscope ERCP is a combination of clinical risk management and device/process control. The points below are general and should be adapted to local protocols.

Safety practices and monitoring

Common safety elements include:

• Appropriate patient selection and preparation based on the indication and alternative options.
• Standard monitoring during sedation/anesthesia, with clear criteria for escalation.
• Radiation safety practices for patient and staff (shielding, positioning, minimizing unnecessary fluoroscopy).
• Clear communication between operator, assistant, sedation/anesthesia team, and fluoroscopy operator.

Because ERCP can be lengthy and technically demanding, fatigue and task overload are real human factors risks. Structured checklists and a culture that welcomes “pause and reassess” can be protective.

Informed consent is also a safety tool. Beyond listing risks, effective consent discussions (and documentation) clarify the intent of the procedure (diagnostic vs therapeutic), what alternatives exist locally, and what the “next steps” might be if ERCP is unsuccessful (for example, referral, repeat attempt, percutaneous drainage, or surgery depending on the scenario).

Common ERCP adverse events to anticipate (high-level)

While complication rates and definitions vary, teams typically plan for the possibility of:

• Post-ERCP pancreatitis
• Bleeding (especially after sphincterotomy)
• Infection (e.g., cholangitis, particularly if drainage is incomplete)
• Perforation
• Sedation/anesthesia-related events (hypoxia, aspiration, hemodynamic instability)

Many institutions use protocol-driven risk reduction strategies (for example, careful cannulation technique, minimizing unnecessary pancreatic duct instrumentation, and patient-specific prophylaxis strategies where adopted). The exact approach should follow local guidelines and the treating clinician’s judgment.

Alarm handling and human factors

Duodenoscope ERCP often involves multiple devices that can alarm or fail:

• Endoscopy processor/light source warnings
• Insufflation or suction issues
• Electrosurgical generator alarms
• Fluoroscopy equipment interruptions

Good practice is to pre-assign who responds to which device and to avoid “alarm fatigue” by addressing root causes (loose connections, blocked tubing, depleted consumables) rather than repeatedly silencing alarms.

Risk controls specific to reusable endoscopes

Key controls that support safety include:

• Reprocessing verification: only use scopes that have completed validated reprocessing and are properly stored.
• Integrity checks: remove the scope from service if damage is suspected (tip defects, cracks, control issues, leak test failure).
• Accessory compatibility: use accessories that are compatible with the scope channel and elevator design to reduce jams and channel damage.
• Traceability: accurate logging supports investigation if there is a suspected device issue later.

Incident reporting culture (general)

Hospitals that use Duodenoscope ERCP safely at scale typically treat near-misses and deviations as learning opportunities:

• Report reprocessing deviations promptly.
• Quarantine equipment when appropriate per policy.
• Involve infection prevention and biomedical engineering early when a device concern is suspected.
• Document device identifiers and reprocessing cycle details in a way that supports root-cause analysis.

How do I interpret the output?

Duodenoscope ERCP produces two main “outputs” that clinicians interpret together:

• Endoscopic video: the live view of the duodenal mucosa and papilla, used to position the scope, assess anatomy, and guide cannulation and therapy.
• Fluoroscopic images: contrast outlines the ductal system, helping the team understand duct anatomy, obstruction patterns, leaks, and the position of wires and stents.

Clinicians typically interpret these outputs by correlating:

• The endoscopic view (papilla appearance, alignment, stability)
• The fluoroscopic view (duct filling, drainage, filling defects, strictures, and device position)
• The broader clinical context (symptoms, laboratory trends, and pre-procedure imaging)

In practical terms, teams often look for patterns: a smooth tapering narrowing may suggest a benign-looking stricture pattern (clinical correlation required), while irregular narrowing can raise concern for malignancy; a rounded filling defect that moves with balloon sweeps may represent a stone; contrast extravasation can suggest a leak. Interpretation always remains contextual and dependent on the full clinical picture.

Common pitfalls and limitations

Interpretation is vulnerable to artifacts and incomplete information, such as:

• Air bubbles or contrast layering that can mimic duct defects.
• Overlapping anatomy or bowel gas that obscures ducts on fluoroscopy.
• Incomplete duct filling, which can miss pathology if a segment is not opacified.
• Projection effects where a stricture or stone appears different depending on angle.

False positives and false negatives are possible. ERCP findings should be interpreted with clinical correlation and, when needed, complementary imaging or endoscopic techniques.

What if something goes wrong?

A structured response protects patients and helps preserve expensive hospital equipment. The checklist below is general and should align with local escalation pathways.

Troubleshooting checklist (common issues)

• No image / poor image
• Check processor settings, light source, and cable connections.
• Confirm the correct input is selected and perform system checks (e.g., white balance if required).

• If unresolved, switch to a backup scope or tower per policy.

• Poor suction or insufflation

• Check suction canister, tubing kinks, and valve orientation.
• Confirm the correct valves are installed and not blocked.

• Flush channels per IFU; if resistance persists, stop and assess for channel obstruction.

• Accessory won’t pass

• Reposition the scope to reduce bends and torque.
• Adjust the elevator position and straighten the accessory.

• Do not force; consider changing the accessory or removing the scope from service if damage is suspected.

• Elevator or angulation control malfunction

• Stop accessory manipulation immediately.
• Withdraw the scope safely if control is compromised.

• Tag the scope out of service and notify biomedical engineering.

• Suspected contamination or reprocessing breach

• Do not use the scope.
• Quarantine and follow infection prevention and reprocessing deviation policies.

Other “things that go wrong” can be procedural rather than purely device-related. Examples include inability to cannulate the intended duct, unexpected anatomy, or difficulty deploying a stent due to tight strictures. When this happens, a useful team mindset is to slow down and re-confirm goals, available rescue options (different accessories, different approach, referral), and the patient’s stability before escalating complexity.

When to stop use

Stop the procedure and escalate when:

• Device control is unreliable (angulation/elevator failure).
• Visualization is lost and cannot be promptly restored.
• Equipment malfunction creates immediate patient risk.
• A serious clinical complication is suspected (managed under clinical protocols).

When to escalate to biomedical engineering or the manufacturer

• Biomedical engineering: repeated functional failures, suspected leaks, image chain problems, tower issues, or recurrent accessory channel resistance.
• Manufacturer/vendor service: scope repairs, warranty questions, IFU clarifications, reprocessing compatibility questions, and post-repair performance validation steps (as defined by contract and policy).

Documentation and safety reporting expectations (general)

Good documentation typically includes:

• Scope identifier/serial number (as recorded by facility process)
• Reprocessing batch/cycle identifiers (if used)
• Description of the malfunction or deviation
• Actions taken (quarantine, repair request, alternative equipment used)
• Internal incident report submission per facility policy

External reporting requirements vary by country and regulator, and should be managed through institutional governance.

Infection control and cleaning of Duodenoscope ERCP

Duodenoscope ERCP infection control is a high-priority topic because the device has complex, hard-to-clean structures and is reused across patients. This section provides general principles; always follow the manufacturer’s IFU and your facility’s infection prevention policy.

Why duodenoscopes are challenging to clean

Compared with many other flexible endoscopes, duodenoscopes often include:

• A distal elevator mechanism with moving parts and tight clearances
• Narrow channels and junctions where organic material can be retained
• A distal tip design that can include seams, lenses, and ports

These features can make duodenoscopes more susceptible to retained soil and biofilm if cleaning steps are rushed, incorrect brushes are used, or drying/storage is suboptimal.

Biofilm risk is a key concept for leaders: once biofilm becomes established, it can be difficult to remove and may reduce the effectiveness of disinfection processes. That is why many programs emphasize not just disinfection chemistry, but also fundamentals like prompt point-of-use cleaning, correct brushing, and thorough drying.

Cleaning vs. disinfection vs. sterilization (practical definitions)

• Cleaning: physical removal of organic material and debris using detergents, brushing, and flushing. Cleaning is essential because disinfection cannot reliably penetrate heavy soil.
• High-level disinfection (HLD): a chemical process intended to kill most microorganisms. The exact scope of microbial kill depends on the disinfectant and process validation.
• Sterilization: a validated process intended to eliminate all forms of microbial life. Whether sterilization is required or feasible for duodenoscopes depends on manufacturer design/validation and local policy.

Facilities may adopt supplemental measures (for example, enhanced surveillance or additional reprocessing steps) depending on local risk assessments and regulatory expectations. Some programs also evaluate newer device designs (including models with removable distal components or single-use options) as part of a broader infection prevention strategy; these choices interact with budget, waste management, and supply continuity.

High-touch points and “high-risk” areas on the device

Staff training should emphasize meticulous attention to:

• The distal tip, including around the elevator mechanism
• The working channel and ports
• Valves and caps (air/water and suction valves), which may be detachable
• Any removable distal components (varies by manufacturer)
• The exterior insertion tube and bending section, which can be contaminated during withdrawal

In addition, the scope’s connectors and control body can be contaminated by gloved hands during procedures; facilities often include these areas in cleaning protocols and emphasize safe handling to reduce environmental contamination in the reprocessing area.

Example cleaning workflow (non-brand-specific)

A common endoscope reprocessing workflow includes:

1. Point-of-use pre-cleaning – Wipe the exterior, suction detergent/water through channels as instructed, and prevent drying of debris.

2. Safe transport – Move the scope in a closed, labeled container to reduce environmental contamination.

3. Leak testing – Perform leak testing per IFU to detect damage that could allow fluid intrusion and internal contamination.

4. Manual cleaning – Disassemble removable parts. – Brush and flush all accessible channels with the correct brush type and size. – Pay special attention to distal tip and elevator-related structures as described in the IFU.

5. Rinse – Rinse thoroughly to remove detergent residues.

6. High-level disinfection or sterilization – Use an automated endoscope reprocessor (AER) or validated manual process, following exact contact times, concentrations, and temperature requirements defined by the disinfectant and IFU.

7. Final rinse and drying – Rinse (if required by the process), then dry channels using forced air methods as specified. – Drying and storage are critical; residual moisture can support microbial growth.

8. Storage – Store in a clean, controlled environment (often a ventilated cabinet), protecting the distal tip from contact and damage.

9. Traceability documentation – Record scope ID, reprocessing cycle details, staff identifiers (as required), and patient linkage per policy.

Specific steps—especially around elevator cleaning, removable components, and drying requirements—vary by manufacturer.

Drying, storage, and “time out of cabinet” considerations

Many programs have learned that disinfection is only part of the safety story. Practical considerations that can influence contamination risk include:

• Channel drying effectiveness: using the correct drying steps, forced air, and (where used) alcohol flushes per IFU can reduce residual moisture that supports microbial growth.
• Storage cabinet design and maintenance: ventilated storage may reduce moisture retention, but cabinets must be maintained, cleaned, and used correctly (for example, scopes should not touch each other at the distal end).
• Handling during retrieval and transport to the procedure room: clean scopes can be re-contaminated by poor handling, non-clean containers, or storage area crowding.
• Defined “hang time” or shelf-life policies: some facilities set policies for how long a reprocessed scope can remain in storage before it requires reprocessing again. These policies are driven by local governance and standards rather than a single universal rule.

Quality assurance and process control

Operationally mature programs often include:

• Competency validation for reprocessing staff, with periodic reassessment
• Audits of cleaning steps, documentation completeness, and storage conditions
• Inspection tools (e.g., visual inspection and, where adopted, borescope inspection) to identify retained debris or damage
• Preventive maintenance schedules to keep channels, seals, and controls in good condition
• Clear quarantine and escalation pathways for scopes that fail checks

Some facilities also adopt microbiological surveillance programs (for example, periodic culturing of scopes) or other verification methods based on local risk assessment. These programs require clear governance: defined sampling methods, action thresholds, quarantine processes, and communication pathways to avoid ad hoc responses.

The right approach depends on local resources, scope volumes, and regulatory expectations.

Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer)

A manufacturer is the company responsible for designing, producing, labeling, and supporting a medical device under its name and regulatory quality system. An OEM (Original Equipment Manufacturer) may build components or even complete devices that are then branded and sold by another company, depending on commercial arrangements.

In endoscopy ecosystems, OEM relationships can affect:

• Parts availability and repair logistics
• Compatibility between scopes, processors, and accessories
• Service documentation, training pathways, and software lifecycle management
• Standardization opportunities across a hospital network

For hospital decision-makers, the practical takeaway is to evaluate the full support chain: training, authorized service capacity, availability of loaners, and the clarity of responsibility when components come from different sources.

When evaluating duodenoscope platforms, many organizations also consider ecosystem factors that are not obvious in a product brochure: how quickly a damaged scope can be repaired, whether the vendor provides in-service training for reprocessing staff, how service bulletins are communicated, and whether the hospital can standardize processors and scopes across multiple sites to reduce variation.

Vendors, Suppliers, and Distributors

Role differences: vendor vs. supplier vs. distributor

In hospital procurement language:

• A vendor is any company that sells products or services to the hospital (often the term used in contracts and tenders).
• A supplier provides goods (medical devices, consumables, spare parts) and may be a manufacturer or an intermediary.
• A distributor typically purchases from manufacturers and manages warehousing, logistics, local regulatory paperwork (where applicable), sales, and sometimes after-sales support and training coordination.

For Duodenoscope ERCP programs, distributors matter because ERCP depends on rapid access to accessories, reliable loaner scopes, and timely repair logistics—especially for urgent cases.

Hospitals sometimes use hybrid models, such as direct purchase of capital equipment from a manufacturer with accessories supplied through a distributor. Clarity in responsibilities (who provides what, who trains staff, who responds to urgent failures) prevents gaps when the ERCP service is under pressure.
