Mesenteric vein thrombosis after laparoscopic sleeve gastrectomy.

Mesenteric vein thrombosis is a rare complication of bariatric laparoscopic surgery. We report a case of a 47-year-old man with obesity who had mesenteric vein thrombosis 14 days after laparoscopic sleeve gastrectomy. He was treated with heparin anticoagulation with a good therapeutic response. This case and literature review illustrate that mesenteric vein thrombosis has to be included in the differential diagnosis of abdominal pain after a bariatric procedure and listed formally as a complication of bariatric surgery.
