[Spur valve jejunal interposition in choledochus cystectomy].

Area of Science:

• Hepatobiliary Surgery
• Pediatric Surgery
• Surgical Innovation

Context:

• Congenital choledochus cysts (CCC) require surgical intervention.
• Total cystectomy with jejunal interposition is a common surgical approach.
• Evaluating long-term outcomes and complications of surgical techniques is crucial.

Purpose:

• To assess the efficacy and complications of spur valve jejunal interposition for CCC.
• To investigate the mechanisms of bile duct reflux after surgery.
• To propose modifications for conventional Roux-Y anastomosis to prevent reflux.

Summary:

• A study of 113 patients undergoing spur valve jejunal interposition for CCC revealed satisfactory two-year outcomes but noted early complications in 26.5%, including bile leakage and obstruction.
• Late complications included bile duct reflux and abdominal pain, potentially due to bile gastritis, which was not observed with conventional Roux-Y.
• Experimental findings suggest a spur valve prevents reflux by acting as a one-way stopper and narrowing the bile duct; modified Roux-Y anastomosis may further enhance biliary drainage.

Impact:

• Highlights potential complications associated with spur valve jejunal interposition for CCC.
• Provides insights into the pathophysiology of post-surgical bile duct reflux.
• Suggests surgical modifications to conventional Roux-Y anastomosis to improve patient outcomes in CCC treatment.
