Portomesenteric Venous Thrombosis with Bowel Ischemia after Laparoscopic Sleeve Gastrectomy

A bstrAct Laparoscopic sleeve gastrectomy has become an increasingly popular surgical option for morbidly obese patients. Portomesenteric venous thrombosis, as a complication of laparoscopic sleeve gastrectomy, has been rarely reported. We report one case of thrombosis of the portal vein and the superior mesenteric vein after sleeve gastrectomy. It is confirmed by CT scan. Thrombosis of the portomesenteric veins after bariatric surgery is a diagnosis that one should know how to raise in front of any postoperative abdominal pain. An obese patient with a history of thrombosis should receive a complete etiology of these thromboses before bariatric surgery. Abnormal blood dirt, an active smoking fat woman having oral contraceptive, or a patient with a history of recurrent venous thrombosis may be a relative contraindication against a complex bariatric surgery with digestive bypass.
