Radical block resection of hepatoduodenal ligament for carcinoma of the bile duct with double catheter bypass for portal circulation.

A new concept of radical block resection of the hepatoduodenal ligament for carcinoma of the bile duct and new double bypass technique of portal circulation for the procedure were introduced. Clinical experiences of six patients were reported. By combined use of radical block resection of the hepatoduodenal ligament and double bypass technique, the radical resectability of carcinoma of the bile duct became a reality, and improvement of postoperative survival rate is expected.
