Portal Vein Thrombosis a Rare but Life-threatening Complication after Laparoscopic Sleeve Gastrectomy: A 5 Years Study in a Bariatric Center of Excellence.

Background And Aim: Laparoscopic sleeve gastrectomy (LSG) is actually the most performed bariatric procedures in the world, and porto-mesenteric vein thrombosis (PVT) has been increasingly reported as a rare but serious complication. The best algorithm for PVT's prevention and therapy is still under discussion. The aim of this study is to explore the incidence and the outcomes of the PVT after LSG in a Bariatric Surgery Center of Excellence (BS-CoE) and elaborate a diagnostic and therapeutic algorithm for PVT after LSG.
