A prospective trial of a cohort of patients (N = 94) with portal hypertension and history of bleeding was selected for surgery based on strict clinical and laboratory criteria. All of them were treated with portal blood flow preserving procedures. The following selection criteria were used: good cardiopulmonary function without pulmonary hypertension and good liver function (Child-Pugh A). All patients were operated in an elective fashion and the operations performed were: selective shunts (N = 38) (distal splenorenal and splenocaval), low diameter mesocaval shunts (N = 13) and the esophagogastric devascularization with esophageal transection (Sugiura-Futagawa) (N = 43). Patients were selected for each operation according to their anatomical conditions. Sixty-one of the patients were cirrhotics. Operative mortality was 8% and rebleeding was observed in 5% of the cases. Postoperative encephalopathy was seen in seven patients (three selective shunts, two low diameter mesocaval shunts and two devascularizations). In 13 of 62 patients postoperatively evaluated by means of angiography, portal vein thrombosis was shown (seven selective shunts, two low diameter shunts and four devascularizations). Twenty-two patients with preoperative portal vein thrombosis (and treated with a Sugiura-Futagawa operation) were excluded from postoperative angiographic evaluation. Survival (Kaplan-Meier) was 85% at 60 months. Portal blood flow preserving procedures are the treatment of choice for patients with hemorrhagic portal hypertension and good liver function. The kind of operation is selected according to the individual anatomical status of the patient.
