[Congenital cystic dilatation of biliary tract (author's transl)]
Insights
Congenital cystic dilatation of the biliary tract, a rare condition, was observed in a 12-year-old girl. Intravenous cholangiography successfully diagnosed this complete intra- and extrahepatic biliary dilatation before surgery.
Area of Science:
- Gastroenterology and Hepatobiliary Surgery
- Pediatric Surgery
- Medical Imaging
Background:
- Congenital cystic dilatation of the biliary tract is a rare congenital anomaly with various classifications.
- Previous literature describes associations of intra- and extrahepatic cystic dilatation, first reported in 1964.
Observation:
- The case study details a 12-year-old female patient presenting with congenital cystic dilatation of the biliary tract.
- The condition involved both intrahepatic and extrahepatic segments of the biliary system.
Findings:
- Preoperative diagnosis was achieved using intravenous cholangiography.
- Intravenous cholangiography is effective in diagnosing approximately 30% of such complex biliary dilatations.
Implications:
- Accurate preoperative diagnosis of biliary tract anomalies is crucial for surgical planning.
- This case highlights the utility of intravenous cholangiography in identifying rare congenital biliary malformations.
Abstract:
The congenital cystic dilatation of biliary tract is un frequent affection and there are many types described (classification of Alonso Lej). The authors present the observation of a little girl of 12 years who presented a complete cystic dilatation ob biliary tract, diagnosed before the operation by intravenous biligraphy. This association of intra and extra hepatic cystic dilatation has been described in 1964 by Arthur and Stuart, and the diagnosis is to be done by intraveinous biligraphy in 30% of cases.
