Abstract:
Bowel obstruction is a known complication of Roux-en-Y gastric bypass. It can be caused by adhesions, internal hernia, incarcerated ventral hernia, or intussusception. Sometimes the underlying cause may be unusual. These 2 case reports describe patients who underwent laparoscopic Roux-en-Y gastric bypass and whose postoperative courses were complicated by small-bowel obstruction due to phytobezoars in the ileum, distal to the jejunojejunal anastomosis. We reviewed the literature by using PubMed and Medline for causes, pathogenesis, classifications, diagnosis, and management.
