Abstract

Intussusception following Roux-en-Y gastric bypass (RYGB) is a rare complication of bariatric surgery with an unclear etiology. The pathogenesis underlying intussusception after gastric bypass is likely different from that in the general population. Post-RYGB intussusception might be related to motility issues in the divided small bowel, thinning of the mesentery following rapid weight loss, or anastomotic sutures/staple line acting as the lead point. This condition can cause obstruction with subsequent strangulation and bowel necrosis if not recognized and treated promptly. Clinical presentation is vague and nonspecific, and computerized tomography scan represents the diagnostic test of choice. Surgical treatment consists of reduction with or without anastomosis resection and reconstruction. This literature review provides an extensive overview of this condition, based on multiple studies involving 120 patients.
