Insights
This case study details biliary atresia (BA) in an infant with a duplicated common bile duct. Surgical intervention led to a successful outcome, with the infant jaundice-free at 7 months.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Congenital Abnormalities
Background:
- Biliary atresia (BA) is a rare neonatal condition requiring prompt diagnosis and surgical management.
- Common bile duct duplication is an exceptionally rare congenital anomaly.
Observation:
- A 1-month-old infant presented with persistent jaundice, leading to suspicion of BA.
- Intraoperative cholangiography confirmed BA.
- A previously undescribed, parallel fibrous bile duct remnant was identified during surgery.
Findings:
- Histological examination revealed bile duct proliferation in the accessory bile duct remnant.
- The final diagnosis was biliary atresia with a duplicated common bile duct.
Implications:
- This case highlights the importance of meticulous surgical dissection in BA cases.
- Recognizing rare anatomical variations like duplicated bile ducts is crucial for surgical planning and patient outcomes.
- Early portoenterostomy in BA, even with anomalies, can lead to favorable long-term results.
Abstract:
The authors report a case of biliary atresia (BA) with duplication of the common bile duct. A 1-month-old girl was referred for investigation of persistent jaundice. BA was suspected and confirmed with intraoperative cholangiography. A portoenterostomy was performed at 50 days of age. During dissection of the fibrous remnant of the common bile duct, a separate fibrous bile duct remnant running in parallel on the left, was identified. Histologically, there was bile duct proliferation at the porta hepatis of the left bile duct remnant. A diagnosis of BA with duplicated common bile duct was made. Postoperative course was uneventful, and at a follow-up assessment at 7 months, she was jaundice free, and her progress has been unremarkable.
