【Abstract】ObjectiveTo investigate the perioperative management in hepatectomy using hepatic energy metabolisom for enhancing safety of and improving the survival in patients with primary liver cancer (PLC).MethodsTwo thousands and one hundred fortythree patients with PLC were treated in this hospital from January 1990 to January 2004. The perioperative data, operative approach, postoperative treatment, postoperative clinical course and follow up data were retrospectively analyzed. All patients were divided into two groups: the early period group and the late period group(from January 1997 to January 2004) and comparison was taken between two groups. The preoperative redox tolerance index (RTI), intraoperative hepatopetal blood occlusion of half liver, and postoperative arterial ketone body ratio (AKBR) were investigated and evaluated.Results①The proportion of small PLC and resection rate increased, the morbidity of complications and mortality after hepatectomy decreased, also the survival rate prolonged in the late period group. ②When using RTI as an indicator for selection of hepatectomy, the morbidity of complications decreased from 21.1% to 11.0%, the mortality form 1.6% to 0.3%. ③Comparising hepatopetal blood occlusion of total liver (n=476) with half liver (n=523),the postoperative morbidity of complications and mortality were 25.8% to 11.9% and 2.3% to 0.6% respectively. ④Postoperative AKBR measurements was a reliable indicator to assess the energy status of the liver and liver failure.ConclusionRTI is of potential value in predicting preoperative hepatic functional reserve, hepatopetal blood occlusion of half liver could protect the residual liver function, and postoperative AKBR measuremeant is a simple and accurate means of determining the immediate state of metabolic dysfunctioning in liver resection. The authors propose that perioperative treatment is an important factor in decreasing operative complications and mortality rate after liver resection.
