Summary

This study reports the first cases of congenital duodenal obstruction combined with choledochal cysts. Anomalous pancreatobiliary ductal junction (APBDJ) is suggested as a key factor in these rare co-occurrences.

Area of Science:

  • Pediatric Surgery
  • Gastroenterology
  • Congenital Anomalies

Background:

  • Congenital duodenal obstruction is frequently associated with various anomalies.
  • The co-occurrence of duodenal obstruction and choledochal cysts has not been previously documented.

Observation:

  • Two pediatric patients presented with both congenital duodenal obstruction and choledochal cysts.
  • One patient had a diverticulum-type choledochal cyst within an annular pancreas.
  • The second patient had duodenal atresia, imperforate anus, and a choledochal cyst.

Findings:

  • Both patients exhibited high amylase levels in cyst bile, indicative of an anomalous pancreatobiliary ductal junction (APBDJ).
  • Intraoperative cholangiography confirmed APBDJ in one patient.

  • Surgical interventions included cyst excision, choledochojejunostomy, and duodenoduodenostomy.

    • Implications:

    • This association suggests APBDJ may play a significant role in the etiology of choledochal cysts in patients with duodenal obstruction.
    • Highlights the importance of considering APBDJ in neonates with combined duodenal and biliary anomalies.
    • Further research is warranted to elucidate the precise pathogenic mechanisms linking these conditions.
