Further study details as provided by Kochi University:

Primary Outcome Measures:
  • to evaluate the total amount of insulin required for glycemic control after hepatic resection [ Time Frame: total amount of insulin required ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • to investigate the trends of postoperative blood glucose levels and the incidence of severe hypoglycemia (< 40 mg/dL) by using artificial pancreas during intensive care unit stay [ Time Frame: hypoglycemia ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Experimental: 1
receive a preoperative supplementation with carbohydrate and branched-chain amino acids-enriched nutrient
Dietary Supplement: Aminolevan EN
The present study used carbohydrate and BCAA-enriched soft-powder nutrient-mixture for preoperative supplementation. Supplementation with Aminolevan EN (100 g per day) started at two weeks prior to the surgery under the careful monitoring of compliance.
Other Name: Aminolevan EN
Placebo Comparator: 2
receive a preoperative supplementation without carbohydrate and branched-chain amino acids-enriched nutrient
Dietary Supplement: Placebo
Other Name: No receive, normal diet

Detailed Description:

Twenty-six patients with hepatectomy due to a live tumor were prospectively randomized to receive a preoperative supplementation with carbohydrate and branched-chain amino acids-enriched nutrient or not.
