The morbidity and mortality of major abdominal surgical interventions in 34 histologically proven cirrhotic patients are analysed by the authors. The surgical interventions were carried out based on vital absolute and elective indications. 37 general and surgical complications were observed following the major abdominal surgery of 34 cirrhotics. 7 out of 34 patients died, the mortality was 21%. Suture insufficiency, peritonitis, sepsis and other inflammatory processes occurred most frequently among the complications. The Child criteria, the prothrombin level and white blood cell count proved to be useful prognostic factors.
