Portal vein thrombosis following laparoscopic total mesorectal excision: case report

Data continue to grow regarding the safety and technical feasibility of laparoscopically assisted total mesorectal excision (TME). As this minimally invasive alternative to open colonic resection becomes more popular, it is inevitable that information on the benefits and complications associated with it will continue to expand. Portal vein thrombosis (PVT) has been reported after a variety of laparoscopic procedures. We report a case of superior mesenteric, splenic and portal vein thrombosis following laparoscopically assisted TME. To our knowledge, this complication of laparoscopic TME has not been previously reported in the literature. PVT should be ruled out in patients who present with vague abdominal symptoms. The course of this complication, while potentially devastating, is usually benign and responds well to lysis and/or anticoagulation.
