Abstract:
Laparoscopic gastric bypass is the most common type of surgery for morbid obesity in Denmark. The most frequent late complications after gastric bypass are ulcer, internal hernia and stenosis. Two cases of stenosis of the bileopancreatic limb with gastric blow-out are described. Urgent diagnosis with computed tomography and acute surgical treatment is vital as the complication can lead to gastric necrosis, pancreatitis, biliary stasis, sepsis and multi-organ failure within a very short time. Prompt contact to specialized surgeons is advocated.
