Comparing terlipressin and somatostatin to lower portal pressure during living-donor liver transplant

Official title: Comparison of the Effects of Terlipressin and Somatostatin on Portal Pressure in Patients Undergoing Living Donor Liver Transplantation

Run by Istanbul Medipol University Hospital · NCT07304466 · Data updated 2026-11-12

This trial tests whether terlipressin or somatostatin better lowers portal pressure and reduces bleeding and transfusion needs in people having a right-lobe living-donor liver transplant.

Is this trial a fit for you?

Likely a good fit

Adults scheduled for right-lobe living-donor liver transplantation with clinically significant portal hypertension (for example varices, thrombocytopenia <100,000, ascites, or encephalopathy) and Child–Turcotte–Pugh class B or C who meet inclusion criteria.

Probably not a fit

Patients with portal vein thrombosis, severe chronic renal failure (GFR ≤30%), active myocardial ischemia, uncontrolled hypertension, arrhythmia, portopulmonary hypertension, acute-on-chronic liver failure, or those already treated with terlipressin for hepatorenal syndrome are unlikely to benefit or are excluded.

What this trial studies

This interventional trial gives patients undergoing right-lobe living-donor liver transplantation either somatostatin or terlipressin to compare effects on portal pressure and clinical outcomes. Direct portal pressure is measured at baseline, five minutes after a bolus dose, after portal vein and hepatic artery anastomoses, and after splenic artery ligation if performed, while continuous hemodynamic monitoring is recorded. Dosing is somatostatin 250 mcg bolus then 2.5 mcg/kg/hr infusion and terlipressin 1 mg bolus then 2 mcg/kg/hr infusion, continued intraoperatively and for 24 hours postoperatively. The study compares changes in portal pressure, bleeding, transfusion requirements, and perioperative hemodynamics between the two groups.

Why it matters

Potential benefit: If one drug proves superior, it could reduce intraoperative bleeding, lower transfusion needs, and improve perioperative renal and hemodynamic outcomes for transplant patients.

How similar studies have gone: Both somatostatin and terlipressin have prior evidence of lowering portal pressure and reducing bleeding in variceal and surgical settings, but direct head-to-head intraoperative comparisons in living-donor liver transplantation are limited.
