Choledochal cyst: a review of 19 cases
Insights
Choledochal cysts present differently in infants versus older children, impacting outcomes. Congenital cystic dilatation may affect younger patients, while acquired forms are seen in older children, suggesting different etiologies.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Hepatology
Background:
- Choledochal cysts are congenital biliary tract malformations.
- Diagnosis and management can be challenging, especially in infants.
- Two distinct clinical presentations have been observed.
Purpose of the Study:
- To review cases of choledochal cysts.
- To identify distinct patient groups based on age and presentation.
- To evaluate outcomes and suggest etiological differences.
Main Methods:
- Retrospective review of nineteen choledochal cyst cases.
- Classification of patients into two age-based groups.
- Analysis of clinical presentation, associated conditions, and surgical outcomes.
Main Results:
- Infants (<1 year) showed higher mortality, severe cirrhosis, portal hypertension, and biliary atresia/stenosis.
- Older children (3-20 years) presented with classic symptoms, mild cirrhosis, and choledocholithiasis/pancreatitis.
- Choledochocyst-jejunostomy with cholecystectomy demonstrated fewer long-term complications than choledochocyst-duodenostomy.
Conclusions:
- Younger patients likely have congenital cystic bile duct dilatation.
- Older patients may have an acquired form linked to pancreatic reflux.
- Surgical approach (jejunostomy vs. duodenostomy) impacts long-term outcomes.
Abstract:
Nineteen cases of choledochal cyst are reviewed. Two distinct groups of patients were identified. Patients under one year of age, initially diagnosed as having biliary atresia, had a higher mortality rate, a higher incidence of severe cirrhosis with portal hypertension, and associated atresia or stenosis in the biliary tree. The second group, presenting between 3 and 20 years of age with more classic symptoms, had mild cirrhosis without portal hypertension and had associated choledocholithiasis and pancreatitis. It is suggested that the younger patients had a congenital form of cystic bile duct dilatation and that the older patients had an acquired form, perhaps related to a common channel with reflux of pancreatic juice into the common bile duct. Postoperative follow-up supports the current view that choledochocyst-jejunostomy with choleystectomy has a lower rate of long-term complications than does choledochocyst-duodenostomy.
