Transduodenal Sphincteroplasty: A Visual Case Study

Sphincter of Oddi dysfunction is a challenging and rare clinical entity resulting in pancreatobiliary pain and stasis of bile and pancreatic juice. This problem was classically treated with surgical therapy, but as classification of the disease has changed and newer methods of endoscopic evaluation and therapy have evolved, operative transduodenal sphincteroplasty is now generally reserved as a final therapeutic option for these patients. In this video and manuscript, we describe our approach to operative transduodenal sphincteroplasty in a patient with type I Sphincter of Oddi dysfunction.

A 50-year-old female with history of Roux-en-Y gastric bypass presented with episodic right-upper-quadrant and epigastric abdominal pain with associated documented elevations in liver chemistries. Preoperative cross-sectional imaging demonstrated dilation of her common bile duct. After multidisciplinary discussion, the decision was made to pursue operative transduodenal sphincteroplasty.

All key operative steps of the transduodenal sphincteroplasty are demonstrated in the embedded video. Key operative steps include laparotomy, generous Kocher maneuver, and duodenotomy over the ampulla, allowing access for sequential biliary and pancreatic sphincterotomies and sphincteroplasties with absorbable suture. The duodenotomy and abdominal fascia are then closed. Our patient underwent sequential diet advancement and was discharged to home on postoperative day five. At clinic follow-up, pancreatobiliary-type pain had resolved.

The embedded video demonstrates a case of operative transduodenal sphincteroplasty, which can provide durable results in appropriate patient populations.
