Obstruction After Laparoscopic Roux-en-Y Gastric Bypass: Roux Obstruction and Biliopancreatic Gangrene up to Ligament of Treitz.

Obstruction after laparoscopic Roux-en-Y gastric bypass (LRYGB) is a known complication. We present a video of a patient who suffered both early Roux limb obstruction, and late Petersen's hernia with proximal biliopancreatic limb volvulus and gangrene up to the ligament of Treitz, and how both were managed.
