Glucose metabolism is adversely affected in patients following major surgery. Patients may develop hyperglycemia due to a combination of surgical stress and postoperative insulin resistance. A randomized trial was conducted to elucidate the effect of preoperative supplementation with carbohydrates and branched-chain amino acids on postoperative insulin resistance in patients undergoing hepatic resection. A total of 26 patients undergoing a hepatectomy for the treatment of a hepatic neoplasm were randomly assigned to receive a preoperative supplement of carbohydrate and branched-chain amino acid-enriched nutrient mixture or not. The postoperative blood glucose level and the total insulin requirement for normoglycemic control during the 16 h following hepatic resection were determined using the artificial pancreas STG-22. Postoperative insulin requirements for normoglycemic control in the group with preoperative nutritional support was significantly lower than that in the control group (P = 0.039). There was no incidence of hypoglycemia (<40 mg/dL) observed in patients, including those with diabetes mellitus, when the STG-22 was used to control blood glucose levels. STG-22 is a safe and reliable tool to control postoperative glucose metabolism and evaluate insulin resistance. The preoperative oral administration of carbohydrate and branched-chain amino acid-enriched nutrient is of clinical benefit and reduces postoperative insulin resistance in patients undergoing hepatic resection.
