Abstract

Even though recent advances in imaging technology has allowed detection of small liver tumors, only 20% of patients with liver tumors benefit from surgical resection. The reason for this low incidence of resectability in our country is mainly due to decreased liver functional reserve caused by coexisting chronic liver diseases such as cirrhosis or chronic hepatitis [1], Therefore, even when the tumor is small, and is located in the center of one lobe, wide resection may not be advisable. In the last five years, we have reformed the operative procedures and postoperative management according to the redox theory, which involves measurement of the arterial ketone body ratio (AKBR), improving in operative mortality and morbidity [2–7]. In this paper, some of the operative procedures will be presented such as liver resection under hepatic vascular exclusion (HVE) using veno-venous bypass, and hepatic resection using a technique for living related liver transplantation which we have performed in 14 cases in the last 10 months.
