Intussusception After Roux-en-Y Gastric Bypass: Laparoscopic Management.

ABSTRACT

INTRODUCTION: Intussusception represents an uncommon cause of intestinal obstruction after Rouxen-Y gastric bypass. Symptoms are not specific and clinical presentation may vary from acute intestinal obstruction with or without bowel necrosis to intermittent or chronic pain. CT scan is the diagnostic test of choice. MATERIALS AND METHODS: A 38-year-old woman who had undergone RYGBP 5 months prior was admitted to our Emergency Department with acute abdominal pain, alimentary and bilious vomiting, and fever. A CT scan revealed an intussusception after the anastomosis and dilatation of the biliopancreatic limb and the gastric remnant. An emergency laparoscopic exploration was performed. RESULTS: The patient undergoes an explorative laparoscopy. A bowel intussusception starting distally at the jejunojejunostomy and involving the latter is discovered. The common channel is divided first, and after that, the alimentary limb is resected. The biliary limb is identified, marked, and finally divided. A side-to-side jejunojejunal anastomosis is created between the alimentary limb and the common limb. Finally, the anastomosis between the common limb and the biliopancreatic limb is fashioned about 30 cm distally from the latter anastomosis. The total operative time was 130 min. Postoperative course was uneventful, and the patient was discharged on the fifth postoperative day. CONCLUSION: Although rare, intussusception after RYGBP must be considered as a possible cause of intestinal obstruction. In case of a small bowel intussusception, a surgical resection is recommended. A laparoscopic approach to treat bowel intussusception after RYGBP is safe and feasible.
