This case study describes a rare pancreatic bladder anomaly, potentially a double gallbladder draining into the pancreatic duct. Surgical intervention confirmed the aberrant duct

Area of Science:

  • Gastroenterology and Hepatobiliary Surgery
  • Congenital Anomalies
  • Anatomical Variations

Background:

  • Biliary ductal system anomalies are uncommon, presenting diagnostic and therapeutic challenges.
  • The case involves a rare presentation initially diagnosed as gallbladder duplication in a pediatric patient.

Observation:

  • A 6-year-old boy underwent cholecystectomy for a smaller gallbladder, presumed to be duplication.
  • Histological analysis confirmed gallbladder-like tissue in the removed aberrant structure.
  • At age 25, relaparotomy revealed the aberrant duct directly connected to the pancreatic duct (duct of Wirsung) and fusiform dilatation of the extrahepatic bile duct.

Findings:

  • The anomaly, termed pancreatic bladder, involves a cystic duct directly joining the pancreatic duct.

  • This condition can also be interpreted as a double gallbladder anomaly with unusual drainage.
  • Surgical management included excision of the extrahepatic bile duct, the remaining gallbladder, and the aberrant duct.

    • Implications:

    • This case validates the concept of a pancreatic bladder, highlighting a rare congenital biliary anomaly.
    • Understanding such anomalies is crucial for accurate diagnosis and surgical planning in hepatobiliary conditions.
    • Further research into the embryological origins of these dual gallbladder and pancreatic duct anomalies is warranted.
