Association of oesophageal atresia and cholecystohepatic duct

Area of Science:

• Hepatobiliary surgery
• Pediatric surgery
• Congenital malformations

Background:

• Oesophageal atresia is a congenital anomaly requiring complex management.
• Hepatobiliary malformations can present with varied clinical features.
• The cholecystohepatic duct is a rare variant of biliary ductal anatomy.

Observation:

• Two pediatric cases with oesophageal atresia were found to have a rare hepatobiliary malformation.
• The common hepatic duct drained directly into the gallbladder or cystic duct, forming a cholecystohepatic duct.
• This specific combination of anomalies is exceptionally uncommon.

Findings:

• The study documents the occurrence of a cholecystohepatic duct in conjunction with oesophageal atresia.
• This finding underscores the potential for co-occurrence of gastrointestinal and hepatobiliary congenital defects.
• Literature review confirms the rarity of accessory hepatic ducts and cholecystohepatic ducts.

Implications:

• Early recognition of such rare anomalies is crucial for appropriate surgical planning and patient management.
• Increased awareness among clinicians can aid in diagnosing similar rare cases.
• Further research into the embryological basis of these combined anomalies may be warranted.
