There is a wide variation of reported incidence of small bowel obstruction (SBO) after laparoscopic Roux-en-Y gastric bypass (LGB). There is also wide variation in technique, not only in placement of the Roux limb, but also regarding closure or nonclosure of the mesenteric defects. The objective of this study was to examine the incidence and characteristics of SBO after antecolic antegastric bypass with nonclosure of the mesenteric defect of the jejunojejunal anastomosis. ⋯ SBO after LGB is a relatively common complication. The incidence of SBO from IH with nonclosure of the mesenteric defect is similar to that in other series where the defect is closed. Regardless of the cause of the SBO, operative treatment of the patient who has a gastric bypass remains the definitive standard and should not be delayed.
