Fatal portal thrombosis after laparoscopic Nissen fundoplication Trombosis mesentérica y portal tras funduplicatura de Nissen lasparoscópica

Abstract

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.La trombosis venosa mesentérica y portal es una complicación infrecuente de la cirugía laparoscópica. Presentamos el caso de un varón de 20 años, consumidor de cocaína inhalada, al que se realiza una funduplicatura de Nissen laparoscópica, administrándose 20 mg de enoxaparina (Clexane® , Aventis Pharma, Spain) preoperatoriamente. El séptimo día postoperatorio, el paciente presenta una trombosis venosa mesentérica y portal, que se confirma en la laparotomía, con necrosis de todo el intestino delgado y segmentaria del colon, falleciendo el paciente a las 24 horas, a pesar de la terapia anticoagulante y confirmándose el diagnóstico en la necropsia. La trombosis mesentérica y portal es una complicación infrecuentre, pero grave y potencialmente mortal, de la cirugía laparoscópica del reflujo gastroesofágico. Cuando se asocian varios factores predisponentes con un potencial trombótico demostrado aislado, como la cirugía laparoscópica y el consumo de cocaína, no parece que las dosis habituales de profilaxis tromboembólica sean suficientes para evitar esta grave complicación
