Résumé
Objective To review our experiences in portaazygous disconnection for the treatment of portal hypertension and to analyze the causes of postoperative complications. Methods We reviewed the results of 236 patients with portal hypertension who were treated with disconnection from April 1994 to July 2002. Results Postoperative complications occurred in 65 of all the patients(the incidence rate was 27.5%). Twenty-four patients experienced postoperative infection(10.2%),12 patients suffered from intraabdominal massive bleeding(5.1%),12 from massive ascites (5.1%),8 patients suffered from recurrent upper gastrointestinal bleeding (3.4%),7 patients experienced acute thrombosis of portal venous system(3.0%). Two patients suffered from multiple organ dysfunction syndrome (1.0%). The operative mortality was 3.4%(8/236). The main causes of death included intraabdominal massive bleeding and severe infection with MODS. Conclusions The occurrence of postoperative complications was related with the selection of patients,thorough portaazygous disconnection and perioperative management.
