A novel model for training in ERCP with double-balloon enteroscopy after abdominal surgery

Area of Science:

• Gastroenterology
• Surgical Simulation
• Medical Education

Background:

• The compactEASIE model is widely used for gastrointestinal endoscopy training, including ERCP.
• Training for ERCP using double-balloon enteroscopy (DBE) in post-surgical patients is not yet established.

Purpose of the Study:

• To present a specialized organ preparation for the compactEASIE model.
• To enable simulation of ERCP in patients with prior abdominal surgery.

Main Methods:

• Utilized two abdominal organ packages from slaughtered pigs.
• Created a postsurgical anatomy with a Roux-en-Y anastomosis.
• Simulated ERCP procedures in this prepared model.

Main Results:

• Successfully established a life-like training model for ERCP in a postsurgical setting.
• Achieved cannulation of the papilla and successful contrasting of the biliary system.
• Performed sphincterotomy, stent placement/exchange, and needle-knife sphincterotomy.

Conclusions:

• Modified organ preparations facilitate ERCP simulation and training in post-surgical anatomical models.
• This approach enhances training for complex endoscopic retrograde cholangiopancreatography procedures.
