The portoenterostomy procedure for biliary atresia: a five year experience

Area of Science:

• Pediatric Surgery
• Hepatology
• Gastroenterology

Background:

• Biliary atresia is a historically fatal disease in infants.
• The portoenterostomy (Kasai) procedure has significantly improved patient outlook.
• Early diagnosis and surgical intervention are critical for managing biliary atresia.

Purpose of the Study:

• To evaluate the long-term outcomes of the Kasai portoenterostomy procedure in infants with biliary atresia.
• To determine the correlation between ductal histology and postoperative results.
• To assess the efficacy of surgical treatment in modifying the disease process.

Main Methods:

• Retrospective analysis of 37 infants undergoing portoenterostomy (Kasai procedure) between 1972 and the study period.
• Diagnostic operative cholangiography and liver biopsy for suspected obstructive jaundice.
• Portojejunostomy or portocholecystostomy based on intraoperative findings of ductal patency.

Main Results:

• Bile drainage achieved in 26 of 37 patients (70%).
• Seventeen patients (46%) showed near-normal growth and development postoperatively.
• Progressive hepatic fibrosis was observed in 14 patients despite bile drainage, indicating multifactorial disease progression.

Conclusions:

• The Kasai portoenterostomy can achieve bile drainage and improve outcomes in a majority of infants with biliary atresia when performed before three months of age.
• Histological examination of ductal tissue correlates with surgical outcomes.
• Extrahepatic biliary atresia is a dynamic process, and early surgical treatment can favorably modify the disease in approximately 50% of cases.
