Biliopancreatic Limb Obstruction Due to an Unexpected Variant of Internal Hernia After Roux-en-Y Gastric Bypass

Abstract

Small bowel obstruction due to internal hernia (IH) is a well-known late complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). A reliable and immediate diagnosis of IH is important for optimal and timely management of patients with a history of LRYGB. Mesenteric defects that are created during a LRYGB include the following: (1) through the transverse mesocolon defect, (2) through the entero-enterostomy mesenteric defect, and (3) through the space between the mesentery of Roux limb and transverse mesocolon (Petersen’s space). The aim of this case is to present an unusual variant of IH after LRYGB that was laparoscopically explored and treated.
