OBJECTIVETo evaluate long-term outcomes of minor liver resection for hilar cholangiocarcinoma (HC) of Bismuth-Corlette type III.

METHODSFrom January 1997 to December 2007, the clinical data of 91 patients with Bismuth-Corlette type III HC underwent hepatectomy were collected and analyzed retrospectively.

RESULTSThere were 60 patients underwent minor hepatectomy, and 31 undergoing major hepatectomy. Hepaticojejunostomy was made conventionally in an end-to-side fashion in the patients undergoing major liver resection, and a new technique of hepaticojejunostomy used in the patients undergoing minor liver resection. That was the anterior edges of bile duct stumps which were not sutured after suturing of posterior edges. Instead of, the anterior edge of jejunum loop to the remnant liver on the top of the bile duct stumps were sutured with intermittent "U" sutures. In all patients, in-hospital mortality rate was 0 and rate of bile leakage was only 2.1%. The actual 1-, 3- and 5-year survival rates were 91.6% and 87.0%, 61.6% and 62.0%, 31.6% and 33.0%, respectively (P > 0.05).

CONCLUSIONSMinor liver resection for the selected patients with HC of Bismuth-Corlette type III according to our criteria achieved better long-term outcomes. A new hepaticojejunostomy used in the patients undergoing minor liver resection is a safe and effective method.
