To perform radical resection of a subsegment, staining of the subsegment is indispensable. The demarcation area on the surface of the liver is obtained by the conventional technique introduced by Makuuchi and colleagues, but the intersegmental or subsegmental plane in the liver is not recognized by this method. To identify the subsegment in the liver, we have developed a new method that retains the stain in the portal unit parenchyma until the division of the liver is accomplished. The portal venous branch is clamped with a Surgiclip^® under ultrasonic guidance and the subsegment is stained clearly by injection of a sufficient amount of dye into the portal venous branch. In five cases of hepatocellular carcinoma, the subsegment containing the tumor was successfully stained and complete removal of the subsegment was achieved.

Key words
systematic subsegmentectomy, identification of the intersubsegmental plane in the liver, complete removal of the subsegment
