[Surgical resection of hepatic hilar tumors].
Hepatic hilar cancer has an extremely poor prognosis and resection for cure is a realistic possibility in only 15-20% of patients. Tumours confined strictly to the biliary confluence can often be excised locally without resorting to hepatic resection (Bismuth's type I, II). Tumours extending beyond the second order bifurcation (Bismuth's type III) require hepatic resection. In the period 1996-1998 ten patients with hilar cancer (adenocarcinoma) underwent curative resection at our Institution. There were 9 men and 1 women with a mean age of 61.7 years (range 49-76 yrs). One neoplastic lesion was Bismuth's type I, five type II, four type III. The mean preoperative bilirubin level was 20 mg% and the mean duration of jaundice was 4 weeks. Four patients had skeletonization resection of the tumour and extrahepatic bile ducts, clearing all lymphocellular and other tissue from the hepatic pedicle and coeliac axis. Bilioenteric continuity was reestablished by a Roux-en-Y jejunal loop with separate biliary duct anastomoses. Six patients required also hepatic resection to adequately remove the tumour (1 right hepatectomy, 2 right lobectomy, 2 left hepatectomy, 1 segmentectomy III). Three patients had liver metastases. One patient had involvement of the left arterial and portal branch. The postoperative staging was 2 stage II, 1 stage III, 7 stage IV. In 5 patients hepatic lymph nodes (N1) were involved. In no patient the tumour was found at the margin of resection. The median estimated blood loss for hepatic resection was 1,000 ml and for skeletonization 500 ml. Intraoperative mortality was 0%. Operative mortality was 20%. Three patients had a complicated postoperative course (1 cerebral TIA, 1 multiorgan failure, 1 ictus cerebri). All patients died. The mean postoperative survival was 7.4 months. Four patients (N1+) died of local tumour recurrence at 8, 11, 6, and 8 months. In our experience resective procedures can achieve a longer survival and a better quality of life. The operative mortality may be kept to a minimum by adequate selection of patients and technical expertise.
