Insights
Early hepatoportoenterostomy (HPE) improves outcomes for infants with biliary atresia. Infants under 90 days with successful HPE and bile clearance have the best prognosis, often avoiding liver transplantation.
Area of Science:
- Pediatric Surgery
- Hepatology
- Neonatology
Background:
- Biliary atresia is a severe neonatal liver disease requiring timely intervention.
- Accurate diagnosis and surgical management are critical for infant outcomes.
Purpose of the Study:
- To evaluate the treatment and outcomes of infants with biliary atresia.
- To identify prognostic factors for surgical success and long-term survival.
Main Methods:
- Retrospective analysis of 66 infants with biliary atresia.
- Diagnosis confirmed using 99mTc DISIDA scanning.
- Surgical interventions included hepatoportoenterostomy (HPE) and hepatoportocholecystostomy.
Main Results:
- HPE success rate was 25%, with 19% showing improvement.
- Infants under 90 days had a higher HPE success rate (31%).
- Age under 90 days and bile clearance were key prognostic factors for HPE success.
- Liver transplantation offered a 50% survival rate for referred patients.
Conclusions:
- Hepatoportoenterostomy is a beneficial procedure for biliary atresia in infants under 90 days.
- Early diagnosis and intervention significantly impact surgical success and long-term survival.
- Patients with failed HPE or late diagnosis often require liver transplantation.
Abstract:
This report describes the treatment and outcome of 66 infants with biliary atresia. Mean age was 79.8 +/- 33.2 days. Diagnosis was achieved by 99mTc DISIDA scanning. Hepatoportoenterostomy (HPE) was performed in 48 cases and hepatoportocholecystostomy in four, with microscopic ducts at the porta hepatis. Fourteen infants without microscopic ducts did not undergo HPE. Patients were staged according to the postoperative result. HPE was successful in 25% of patients (group A), resulted in improvement in 19% (group B), failed in 43% (group C), and was short-term in 13% (group D). In patients less than 90 days of age, the HPE success rate was 31%; 23% improved, and 33% showed no improvement. Age (less than 90 days) and bile clearance were prognostic determinants of success. Reoperation was useful only in patients with a previously successful HPE. Ten of 20 patients referred for liver transplantation survived (50%) (7/11) survived after liver transplantation and 3/9 on the waiting list). Fourteen of 15 patients in group A remain anicteric and well without liver transplantation. Patients in group B have had extended survival (greater than 3 years) but eventually required transplantation. Patients in group C and children more than 90 days old at diagnosis require early liver transplantation. HPE is a useful procedure when performed in infants less than 90 days of age who have biliary atresia.
