Liver transplantation for Echinococcus granulosus hydatid disease

Area of Science:

• Hepatology
• Transplant Surgery
• Parasitology

Background:

• Hepatic hydatidosis, caused by Echinococcus granulosus, can lead to severe liver dysfunction.
• Complications of hepatic hydatidosis may progress to end-stage liver disease, necessitating liver transplantation.
• Previous surgeries for hydatidosis can complicate subsequent liver transplant procedures.

Purpose of the Study:

• To report the experience with liver transplantation in patients with hepatic hydatidosis.
• To evaluate the outcomes and challenges of liver transplantation in this specific patient cohort.

Main Methods:

• Retrospective review of 6 patients who underwent liver transplantation for complications of Echinococcus granulosus infestation.
• Analysis of patient demographics, surgical procedures, complications, and long-term outcomes.

Main Results:

• Five patients received transplants for end-stage liver disease (secondary sclerosing cholangitis, secondary biliary cirrhosis, postnecrotic cirrhosis).
• One patient presented with acute Budd-Chiari syndrome due to hepatic vein obstruction.
• Postoperative complications occurred, including graft failure and fatal events (cerebrovascular accident, pulmonary embolism).
• Four out of six patients achieved prolonged survival (37-65 months) with good quality of life.

Conclusions:

• Hepatic hydatidosis, though typically benign, can cause hepatic complications requiring liver transplantation.
• Liver transplantation in patients with hepatic hydatidosis is technically challenging and associated with frequent complications.
• Despite challenges, liver transplantation can lead to favorable long-term outcomes and improved quality of life for selected patients.
