Study Details

Study Description

Brief Summary

The primary objective of this interventional study is determine if the future liver remnant can be optimized by improving liver function pre-operatively in patients who are scheduled for major hepatectomy. The main questions it aims to answer are:

  1. Does high-dose insulin therapy improve liver function in the pre-operative setting?

  2. What is the effect of high-dose insulin therapy on liver function and liver regeneration after a liver venous deprivation (LVD) procedure?

  3. What is the relationship between volume hypertrophy and function in the regenerating liver? Participants will receive a 6-hour infusion of insulin and dextrose to maintain a hyperinsulinemic-normoglycemic state in the weeks prior to planned liver surgery to assess its effect on liver function measured by 99m-Tc-Mebrofenin hepatobiliary scintigraphy.

Parallel Assignment
Intervention Model Description:
Group 1 will consist of participants scheduled for liver resection and will undergo high-dose insulin therapy preoperatively to determine if baseline liver function can be optimized/improved, as measured by 99mTc-Mebrofenin HBS. Cytokine profiling will also be collected and analyzed pre- and post-insulin infusion. Group 2 will consist of participants scheduled for liver resection that require LVD. They will then be randomized to two different arms -- control vs high-dose insulin therapy.Group 1 will consist of participants scheduled for liver resection and will undergo high-dose insulin therapy preoperatively to determine if baseline liver function can be optimized/improved, as measured by 99mTc-Mebrofenin HBS.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Group 1: Effect of high-dose insulin therapy on pre-operative liver function

Group 1 will consist of participants scheduled for liver resection and will undergo high-dose insulin pre-operatively to determine if baseline liver function can be optimized/improved, as measured by 99mTc-Mebrofenin HBS.

Drug: High-Dose Insulin Therapy
A baseline blood glucose value will be obtained. Two units of insulin will be administered IV if the blood glucose is > mmol/L. An insulin infusion of 0.12 units/kg/hr will be started. Ten minutes after starting the insulin, and when the blood glucose is < 6 mmol/L, dextrose 20% supplemented with phosphate (30 mmol/L) will be infused. Blood glucose levels will be measured every 15 minutes, and the dextrose infusion rate adjusted to maintain glycemic levels between 4 and 6 mmol/L for a duration of 6 hours. At the end of the 6 hour period, the insulin will be stopped and the dextrose will be weaned off.

Experimental: Group 2: Effect of high-dose insulin therapy on pre-operative liver function after LVD

Group 2 will consist of participants scheduled for liver resection that require LVD. The participants in the experimental arm will receive high-dose insulin therapy after LVD.

Drug: High-Dose Insulin Therapy
A baseline blood glucose value will be obtained. Two units of insulin will be administered IV if the blood glucose is > mmol/L. An insulin infusion of 0.12 units/kg/hr will be started. Ten minutes after starting the insulin, and when the blood glucose is < 6 mmol/L, dextrose 20% supplemented with phosphate (30 mmol/L) will be infused. Blood glucose levels will be measured every 15 minutes, and the dextrose infusion rate adjusted to maintain glycemic levels between 4 and 6 mmol/L for a duration of 6 hours. At the end of the 6 hour period, the insulin will be stopped and the dextrose will be weaned off.

No Intervention: Group 3: Effect of high-dose insulin therapy on pre-operative liver function after LVD

Group 3 will consist of participants scheduled for liver resection that require LVD. The participants in the no intervention arm will not undergo intervention with high-dose insulin therapy after LVD.

Outcome Measures

Primary Outcome Measures

  1. Liver function improvement after high-dose insulin therapy measured with 99mTc-Mebrofenin Hepatobiliary Scintigraphy (HBS). [Baseline to 24-hours post treatment]

    99mTc-Mebrofenin HBS is a diagnostic nuclear medicine imaging procedure used to evaluate liver function by measuring radiotracer uptake and excretion. The outcome will be evaluating a measurable increase in 99mTc-Mebrofenin (measured %/min/meter^2) from baseline scan to post-treatment scan.

  2. Liver function improvement after high-dose insulin therapy after LVD measured with 99mTc-Mebrofenin Hepatobiliary Scintigraphy (HBS). [Baseline to 7 days post treatment]

    99mTc-Mebrofenin HBS is a diagnostic nuclear medicine imaging procedure used to evaluate liver function by measuring radiotracer uptake and excretion. The outcome will be evaluating a measurable increase in 99mTc-Mebrofenin (measured %/min/meter^2) from baseline scan to post-treatment scan.

  3. Liver regeneration improvement after high-dose insulin therapy after LVD measured CT volumetry [Baseline to 7 days post treatment]

    The volume of the liver can be measured from liver protocoled CT scans
