Octreotide vs. Splenic Artery Ligation for Portal Flow Modulation in Living Donor Liver Transplants (SCALOP Trial)

The goal of this clinical trial is to compare two treatments for regulating blood flow in small liver grafts during living donor liver transplantation (LDLT). The main questions it aims to answer are: * Is octreotide (a medication) as effective or better than splenic artery ligation (surgery) in reducing complications after transplantation? * Which treatment better controls blood flow while causing fewer side effects? Researchers will compare octreotide (given through an IV) to splenic artery ligation (performed during surgery) to see which approach works best for patients receiving small liver grafts. Participants will: * Be randomly assigned to receive either octreotide or splenic artery ligation during their transplant surgery * Have their liver blood flow monitored closely during and after surgery Be followed for 90 days and 1 year to track complications, hospital stay, recovery, and survival. This study may help doctors choose safer, more effective treatments for patients needing small liver grafts.
