Introduction:
Intussusception after one anastomosis gastric bypass is a rare postoperative complication that occurs with bowel obstruction. The diagnosis may be challenging because of long-standing, intermittent, nonspecific symptoms. Our paper describes an unusual case of antegrade intussusception that occurred 28 months after laparoscopic one anastomosis gastric bypass surgery.
Presentation:
A 30-year-old female known to have diabetes mellitus type 2, who presented with epigastric pain. A computed tomography scan revealed a jejuno-jejunal intussusception. After resection and primary end-to-end hand-sewn anastomosis of the biliary limb, the patient was discharged on the 6th day postoperatively and recovered uneventfully. We belief this is the first report describing a case of intussusception post one anastomosis gastric bypass.
Discussion:
Gastric bypass surgeries have recently become a popular method for the surgical treatment of morbid obesity worldwide. The reported intussusception incidence after Roux-en-Y gastric bypass (RYGB) is approximately 0.1-0.3%, but not described in one anastomosis gastric bypass surgery. Approximately two-thirds of patients show recurrent chronic and colicky pain. Surgical intervention is essential.
Conclusion:
Clinicians should be aware of such condition in patients with history of bariatric surgery who present with long-standing, intermittent abdominal pain.
