The evolution of liver transplant program in Pakistan and the challenges ahead

The burden of Liver disease has significant implications on the healthcare infrastructure in Pakistan, with viral hepatitis being the leading etiology of end-stage liver disease. Liver transplant remains the only curative treatment option for end-stage liver disease. A decade ago, the liver transplant facility was almost non-existent for the Pakistani population, and the patients with end-stage liver disease had to travel overseas to receive liver transplantation. Gradually, during the last decade the country has progressed steeply and achieved various milestones in living donor liver transplantation. Various public and private sector hospitals are providing liver transplant services nationwide. The study aimed to describe the evolution and success of living donor liver transplant programs in Pakistan. We will also discuss the current practices involved in donor and recipient selection, factors related to non-existent deceased donor organ programs, and the introduction of innovative strategies to overcome the shortage of donor organ pools. We retrospectively analyzed the data of the first 416 living donor liver transplants (LDLTs) performed at PKLI&RC from March 2019 to April 2023. The stepwise approach for the donor and recipient selection process is described in detail, along with the survival outcomes of LDLT at our center. Among the 416 living donor liver transplants performed between March 2019 and April 2023. The Hepatitis C virus was the most common etiology (50.5%) for chronic liver disease. Hepatocellular carcinoma (HCC) was present in 27.9% of cases. Most donors were offspring of the recipients, with sons accounting for 23% and daughters for 17.5% of cases. Only a single (0.24%) patient had a deceased donor transplant. The annual donor rejection rate was up to 68% at our center. Nine SWAP transplants were performed to overcome the donor shortage. The Clavien Dindo classification system was used to grade the severity of complications after donor hepatectomy. No donor mortality (grade-5 complication) was observed in our cohort, whereas 1- and 3-year recipient survival rates were 89% and 88%, respectively. Hepatitis C virus remains the most common etiology of chronic liver disease requiring liver transplantation. The major pool of living donations was from first-degree relatives. There was no donor mortality with acceptable 1- and 3-year recipient's survival rates. Living donor liver transplantation is a feasible and safe strategy in regions where cadaveric liver transplant program is limited.
