Pigment gallstones of the common bile duct in infancy
Insights
This study found that pigmentary gallstones in infants under six months can cause cholestatic jaundice. Prompt diagnosis and surgical intervention, including calculi removal and bile duct repair, led to successful outcomes without recurrence.
Area of Science:
- Pediatric Gastroenterology
- Hepatology
- Surgical Pediatrics
Background:
- Cholestatic jaundice and gallstones are rare in infants under six months.
- Biliary tract issues in neonates and infants require prompt evaluation and management.
Purpose of the Study:
- To investigate the clinical presentation, diagnosis, and management of gallstones causing cholestatic jaundice in infants.
- To characterize the nature and origin of cholelithiasis in this pediatric population.
Main Methods:
- Retrospective analysis of ten infants (<6 months) with cholestatic jaundice and gallstones.
- Diagnostic tools included ultrasound, percutaneous transhepatic cholangiography, and surgical exploration.
- Analysis of stone morphology, bile, and stone composition.
Main Results:
- Six infants had distal common bile duct stones; four had stones with bile duct perforation, suggesting secondary formation due to stasis and infection.
- Eight infants underwent calculi removal and drainage; two required biliary reconstructive surgery for severe duct lesions.
- Pigmentary cholelithiasis was confirmed in all cases.
Conclusions:
- Infantile gallstones causing cholestatic jaundice can be successfully treated with surgical intervention.
- Bile duct perforation is a significant complication associated with gallstones in this age group.
- Pigmentary stones are the likely etiology in infants presenting with cholestatic jaundice and cholelithiasis.
Abstract:
Ten infants of less than 6 months of age presented with cholestatic jaundice and gallstones. Jaundice occurred after a lag period, and sepsis was present in three children. Ultrasound examination showed dilatation of intrahepatic and extrahepatic bile ducts in eight patients and detected cholelithiasis in three. Percutaneous transhepatic cholangiography and/or surgery allowed separation of the patients into two groups: (i) six children with lithiasis in the distal common bile duct, and (ii) four children with lithiasis associated with bile duct perforation at the junction between the cystic and common bile ducts with gallstones probably secondary to bile stasis and infection. Surgical treatment was confined to removal of calculi and drainage in eight children; biliary reconstructive surgery was necessary in the other two who had serious biliary duct lesions. No recurrence was observed after 1 to 7 years. The pigmentary nature of cholelithiasis was established by stone morphology in all cases, and by bile and stone analysis in several cases.
