Intervention

Device:
• aScope™ Duodeno endoscope and aBox™ Duodeno
The aScope™ Duodeno endoscope is a sterile single-use disposable duodenoscope indicated for endoscopic retrograde cholangiopancreatography (ERCP) procedures.The aScope™ Duodeno endoscope is designed to be used with aBox Duodeno, endoscopic accessories and other ancillary equipment for ERCP procedures. The aBox Duodeno is the console that is necessary for processing the endoscope camera´s video image, regarding the remote switches and output video and recorder data. The aBox Duodeno is designed to be used with the aScope™ Duodeno endoscope.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	To evaluate safety of the aScope™ Duodeno endoscope in ERCP.	Safety will be assessed based on the incidence rates of adverse events based on the seriousness and relatedness to the device and/or procedure.	Day 30 (+3) Post-Procedure
Primary	To evaluate the ERCP procedural success rates with the aScope™ Duodeno endoscope when completing the ERCP procedure for the intended indication(s).	Procedure success will be defined as the successful completion of the ERCP procedure with the aScope™ Duodeno endoscope. The procedural success rate will be the incidence rate of success for the ERCP procedure.	Procedure Completion (Day 0)
Secondary	To establish comprehensive performance attributes of aScope™ Duodeno endoscope through its use by multiple endoscopists in conducting various ERCP procedures.	Procedure success for sub categories of ERCP procedures will be defined as the successful completion of the ERCP procedure with the aScope™ Duodeno endoscope. The procedural success rate will be the incidence rate of success for the stratified sub-categories of ERCP procedures with the the aScope™ Duodeno endoscope.	Procedure Completion (Day 0)
Secondary	To evaluate rate of conversion to a reusable endoscope, other endoscope or an open procedure from the aScope™ Duodeno endoscope during the ERCP procedure.	Rate of conversion will be measured by the incidence rate of when a conversion to a different endoscope or open procedure is necessitated during the ERCP procedure with the aScope™ Duodeno endoscope.	Procedure Completion (Day 0)
Secondary	To evaluate rate of successful completion of a converted ERCP procedure.	Successful completion will be measured by the incidence rate of success for converted ERCP procedure as stratified by the conversion method (reusable scope, other endoscope, other procedure).	Procedure Completion (Day 0)
Secondary	To evaluate the device deficiency rate for the aScope™ Duodeno endoscope.	Incidence rate of device deficiencies as defined as either a device failure or device malfunction for the aScope™ Duodeno endoscope during ERCP procedure.	Procedure Completion (Day 0)
Secondary	To evaluate physician satisfaction with the aScope™ Duodeno endoscope.	Physician reported outcomes questionnaire on physician satisfaction with the aScope™ Duodeno endoscope for ERCP procedures.	Procedure Completion (Day 0)
