title: Mesenteric Torsion as a Cause of Late Abdominal Pain after Gastric Bypass Surgery.
abstract: Gastric bypass (GBP) has been the most common surgical way to treat obesity and its comorbidities. Late abdominal pain may occur by gastro-jejunal ulcers, gallstones, internal herniation or, rarely, intussusception. In an area with more than 1000 GBPs performed yearly, three patients with primary small bowel volvulus causing abdominal pain and requiring emergency or semi-urgent surgery were identified. Patients' histories, radiology, and surgery performed are presented. Weight loss followed by mesenteric narrowing of the root and thus relative elongation may make rotation of the small bowel mesentery possible. Such a torsion might be an overlooked differential diagnosis in obscure abdominal pain after GBP.
