Biliary tract duplication is a rare congenital anomaly. This case highlights diagnosis via T-tube cholangiography in a pediatric patient, emphasizing its importance in identifying rare biliary tract malformations.

Area of Science:

  • Gastroenterology
  • Pediatric Surgery
  • Medical Imaging

Background:

  • Duplication of the biliary tract is an exceedingly rare congenital anomaly.
  • Previous pediatric cases are sparsely documented, primarily in Japanese literature.
  • Diagnostic methods have included endoscopic retrograde cholangiopancreatography (ERCP) and incidental findings during surgery.

Observation:

  • A 13-year-old girl presented with choledocholithiasis, diagnosed via preoperative and intraoperative cholangiography.
  • Postoperative T-tube cholangiography revealed residual stones and, uniquely in an oblique view, suggested biliary tract duplication.
  • Surgical re-exploration confirmed complete duplication from the porta hepatis to the suprapancreatic area.

Findings:

  • T-tube cholangiography, particularly oblique views, can be crucial for diagnosing rare biliary tract duplications.

Related Experiment Videos

  • This case represents a rare instance of pediatric biliary tract duplication diagnosed postoperatively.
  • Complete surgical dissection confirmed the extent of the duplication.

    • Implications:

    • Highlights the diagnostic utility of T-tube cholangiography in identifying rare biliary anomalies.
    • Contributes to the limited literature on pediatric biliary tract duplication.
    • Underscores the importance of thorough postoperative imaging in complex surgical cases.
