GARCIA DIAZ, R. A. et al. Fatal portal thrombosis after laparoscopic Nissen fundoplication. Rev. esp. enferm. dig. [online]. 2005, vol.97, n.9, pp.666-669. ISSN 1130-0108.

Portal and mesenteric vein thrombosis is a very uncommon complication of laparoscopic surgery, especially after anti-reflux procedures. We report the case of a twenty-year-old man with a history of alcohol and cocaine consumption. A Nissen fundoplication was performed. The patient received a single 20-mg dose of enoxaparin (Clexane^®, Aventis Pharma, Spain) two hours before surgery for antithrombotic prophylaxis. On the seventh postoperative day the patient had a portal and mesenteric venous thrombosis, which was confirmed at laparotomy, with both extensive small-intestine necrosis and partial colon necrosis. Despite anticoagulant therapy, the patient died 24 hours later. Surgical findings were confirmed at necropsy. Portal and mesenteric venous thrombosis is an uncommon but severe and even fatal complication after laparoscopic anti-reflux surgery. When other pro-thrombotic, predisposing conditions such as laparoscopic surgery and cocaine consumption are present, the usual prophylactic doses of low molecular weight heparin might not be sufficient to protect against this life-threatening complication.
