Portosplenomesenteric thrombosis after laparoscopic gastric sleeve

Abstract

Background: Bariatric surgery is an effective way to lose weight and the laparoscopic gastric sleeve is one of the techniques currently used. Portosplenomesenteric venous thrombosis is a complication that occurs in patients undergoing this surgical technique. At the moment there are no protocols to reduce the risk of this thrombotic event, so we show our experience and propose an algorithm. Case report: A total of 620 patients were evaluated, six of whom presented between postoperative days 10 to 20 abdominal pain, nausea and dehydration. Therefore, a double contrast abdominal computed tomography scan was carried out, which demonstrated portomesenteric and portoesplenomesenteric thrombosis, in addition to two patients with signs of intestinal ischemia, which required reoperation. One of the patients died of pulmonary thromboembolism.
