A novel second-generation multibending backward-oblique viewing duodenoscope in ERCP

Area of Science:

• Gastroenterology
• Endoscopy
• Medical Device Technology

Background:

• Achieving successful cannulation of the desired duct during ERCP can be technically difficult.
• A novel second-generation multi-bending backward-oblique viewing duodenoscope (2nd M-D scope) was developed to address these challenges.
• This study aimed to assess the effectiveness of the 2nd M-D scope in biliary ERCP procedures.

Purpose of the Study:

• To evaluate the clinical utility and success rate of the 2nd M-D scope for biliary cannulation in ERCP.
• To determine if the 2nd M-D scope offers advantages over conventional duodenoscopes in difficult cases.
• To assess the safety and feasibility of using the 2nd M-D scope in patients undergoing biliary ERCP.

Main Methods:

• Retrospective review of 53 patients undergoing biliary ERCP with the 2nd M-D scope.
• Inclusion criteria: patients with native papilla undergoing biliary ERCP.
• Data collected on cannulation success, procedure completion, and operator feedback.

Main Results:

• Biliary cannulation and interventional procedures were successful in all 53 patients.
• The 2nd M-D scope enabled successful cannulation in two patients where conventional scopes failed.
• Operator feedback indicated the scope's multi-bending feature aided in achieving optimal views for cannulation.

Conclusions:

• The 2nd M-D scope is a safe and effective tool for facilitating biliary cannulation in ERCP.
• The novel design of the 2nd M-D scope enhances procedural success, particularly in challenging anatomies.
• This device represents a valuable advancement for endoscopic retrograde cholangiopancreatography.
