Laparoscopic reduction of small bowel intussusception in a 33-week pregnant gastric bypass patient: surgical technique and review of literature
Intussusception 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.
