# Intussusception Within a Jejunostomy With Closed Loop Obstruction: A Case Report

## TL;DR

This case report describes a rare complication after gastric bypass surgery where part of the intestine folded into itself, causing a blockage that required emergency surgery.

## Contribution

The paper presents a unique case of retrograde jejunal intussusception with closed-loop obstruction following Roux-en-Y gastric bypass.

## Key findings

- The patient had a complicated jejunal intussusception with signs of ischemia and closed-loop obstruction two years after surgery.
- Emergency laparoscopy successfully repaired the hernia and reduced the intussusception with an unremarkable recovery.
- The case highlights the importance of early diagnosis and treatment of this rare postoperative complication.

## Abstract

Jejunojejunal intussusception is a rare yet severe complication of Roux-en-Y gastric bypass (RYGBP) surgery. We are presenting a unique case of retrograde jejunal intussusception with a closed-loop blockage and an associated abdominal herniation that occurred two years after a laparoscopic RYGBP. The patient presented with abdominal pain, nausea, and vomiting, prompting a clinical diagnosis and a biphasic contrast-enhanced computed tomography (CT) scan, which later revealed a complicated jejunal intussusception with signs of ischemia showing decreased wall enhancement and distal collapsed jejunal walls with complete closed-loop bowel obstruction. The case was successfully managed through emergent laparoscopy to repair the hernia and reduce the intussusception, after which the postoperative period was unremarkable. This article aims to raise awareness about this rare but significant postoperative complication and stress the importance of early medical attention in similar cases.
