Laparoscopic resection of intussusception after Roux-en-Y gastric bypass: comparison between the conventional and a simplified approachIntussusception after Roux-en-Y gastric bypass (RYGB) is a rare, long-term complication most commonly occurring in a retrograde fashion just distal to the jejunojejunostomy with approximately .5% incidence . Management options include reduction, pexy, and resection of jejunojejunostomy [2–4]. Our traditional approach in management of symptomatic intussusception is resection and creation of new jejunojejunostomy,y preferably end-to-side anastomosis with a smaller anastomosis of <60 mm. In this video, we compare 2 techniques used to resect the anastomosis.
Plication followed by resection for intussusception after laparoscopic gastric bypassLaparoscopic Roux-en-Y gastric bypass is the most commonly performed surgical intervention for morbid obesity. Internal hernias are the most common cause of postoperative bowel obstruction after laparoscopic Roux-en-Y gastric bypass, with a reported incidence of 3.1% despite mesenteric defect closure [1,2]. A less common cause of postoperative bowel obstruction is small bowel intussusception.
Laparoscopic reduction of small bowel intussusception in a 33-week pregnant gastric bypass patient: surgical technique and review of literatureIntussusception is a rare etiology of bowel obstruction in adults and accounts for 1–3% of those cases. It is associated with an underlying mass such as a tumor or polyp in >80% of patients [1–4]. In gastric bypass patients, intussusception is an uncommon complication [5,6]. The common channel distal to the jejunojejunostomy is the usual site of intussusceptions. The direction of intussusception can be either antegrade or retrograde, but most reported cases are retrograde in nature. The probable etiology can include the presence of an ectopic pacemaker causing retrograde peristalsis.
Intussusception after laparoscopic Roux-en-Y gastric bypassRoux-en-Y gastric bypass (RYGB) has become one of the preferred surgical options for morbid obesity and has been proved effective [1,2]. Laparoscopic RYGB was first introduced by Wittgrove et al.  in 1994. Laparoscopic RYGB remains a challenging procedure because of postoperative complications associated with high morbidity and mortality. We describe 1 case of intussusception after laparoscopic RYGB.
