Hepatic vascular exclusion with veno-venous by-pass and veno-portal by-pass using a Bio Pump was used in hepatectomy in four patients with giant hepatocellular carcinoma occupying the right lobe. Treatment was combined with in situ cold perfusion and surface cooling in three patients. Case 1 was a 46-year-old man whose tumor was resected by extended right lobectomy. Case 2 was a 45-year-old man whose tumor was resected by trisegmentectomy from the right. Case 3 was a 5O-year-old woman whose tumor was resected by right lobectomy. Case 4, 58-year-old woman, underwent tumor resection by extended right lobectomy. The Bio Pump was used for 35, 117, 59 and 38 min, respectively. Total blood loss during surgery was 7555, 2155, 2310 and 1562 cc, respectively. Ascites was observed in 3 patients postoperatively, but all patients discharged in good condition. Hepatic vascular exclusion using a Bio Pump seemed to be used for cases of difficult resection or potential massive hemorrhage during operation.
