Retrograde Intussusception After Roux-En-Y Gastric Bypass for Morbid Obesity

Intussusception after Roux-en-Y gastric bypass procedure (RYGBP) is a rare complication that typically presents late after open or laparoscopic procedures with intermittent partial or complete bowel obstruction. It may be antegrade (peristaltic) or retrograde (antiperistaltic) and usually the common channel is affected. We describe an unusual case of retrograde intussusception that occurred 2 years after a laparoscopic RYGBP in which the proximal common channel had invaginated into the distal anastomotic site and the distal Roux limb.
