Ampullary stenosis following Roux-en-Y gastric bypass (RYGB) is increasingly encountered. We describe cases of biliary obstruction from ampullary stenosis and choledocholithiasis to illustrate the associated diagnostic and interventional challenges with this condition.We reviewed medical records of patients with prior RYGB who underwent a biliary access procedure or surgery for non-malignant disease from January 2012-December 2018.We identified 15 patients (4 male, 11 female; mean age 53.7 years) who had RYGB on average 11.7 years (range 1-32) years before diagnosis of biliary obstruction. Fourteen patients reported abdominal pain, 5 had nausea/emesis, 12 had elevated liver function tests, and 6 had ascending cholangitis. Mean common bile duct (CBD) diameter at presentation was 16.9 mm (range 4.0-25.0 mm). Operations included 3 transduodenal ampullectomies (2 with biliary bypass), 2 CBD explorations with stone extraction, 1 laparoscopic cholecystectomy alone, 1 Whipple procedure, 1 balloon enteroscopy with sphincterotomy, and 7 transgastric endoscopic retrograde cholangiopancreatography. All ampulla pathology was benign in patients who underwent resection. At follow-up (mean 15.4 months; range 0.23-44.5 months), 12/15 (80%) reported symptom resolution or improvement.Ampullary stenosis after RYGB presents challenges for diagnostic evaluation and intervention, often requiring multi-disciplinary expertise. The underlying pathology remains to be elucidated.
