Choledocoduodenal Biliary Bypass for Recurrent Choledocholithiasis in a Patient with Gastric Bypass: An Old Trick to Solve a Modern Problem.

Bariatric patients are at risk for developing biliary stones. Choledocholithiasis poses a significant challenge in Roux-en-Y gastric bypass patients due to anatomical changes, complicating the treatment. We present a case of a 71-year-old female with recurrent choledocholithiasis post-bariatric surgery. After failed endoscopic attempts, a biliodigestive bypass with choledocoduodenal anastomosis was performed successfully using the Da Vinci robotic platform. This technique offers a single anastomosis, excluding the duodenum from transit, preventing food reflux. The patient had an uneventful recovery with no recurrence after 1 year. The choledocoduodenal anastomosis is a viable option for biliary diversion in patients with challenging endoscopic access post-gastric bypass, offering favorable outcomes.
