[Choledochal cysts. Clinico-radiological considerations and surgical technical notes]

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Medical Imaging

Background:

• Neonatal common bile duct cysts are rare congenital anomalies.
• Etiology is debated, potentially involving obstruction or abnormal nerve development.
• Accurate diagnosis is crucial for effective management.

Observation:

• A successful surgical case of neonatal common bile duct cyst is detailed.
• Cystoduodenostomy was the chosen surgical intervention.
• The case highlights diagnostic complexities including co-existing cholostatic cirrhosis and portal hypertension.

Findings:

• Common bile duct cysts are categorized into three anatomopathological types: true cyst, choledochal hernia, and diverticulum.
• True choledochal cysts typically present with mass, jaundice (icterus), and pain.
• Hernias and diverticula are rare, often asymptomatic, and discovered incidentally during surgery or autopsy.

Implications:

• Surgical intervention is the standard treatment for choledochal cysts.
• Surgical options include cyst excision with reconstruction via Roux-en-Y or direct anastomosis to the duodenum.
• This case underscores the importance of early diagnosis and tailored surgical approaches for optimal outcomes in neonatal biliary anomalies.
