Late Perforation of the Distal Roux-en-Y Anastomosis in a Patient with Biliopancreatic Diversion.

A 38-year old female with a history of biliopancreatic diversion for morbid obesity developed a perforation at the distal Roux-en-Y anastomosis 13 months after the original surgery. The etiology of this complication was not determined. Perforation of a Roux-en-Y anastomosis occurring this late in the postoperative period has not been described previously.
