Insights
This study analyzed 36 infants with choledochal cysts, finding that surgical cyst excision and biliary reconstruction is safe and effective, even in infants under one year old.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Congenital Abnormalities
Background:
- Choledochal cysts are rare congenital bile duct anomalies.
- Infantile presentation often involves jaundice and abdominal masses.
- Pancreaticobiliary malunion is a common associated finding.
Purpose of the Study:
- To analyze the clinical characteristics and treatment outcomes of infants with choledochal cysts.
- To evaluate the safety and efficacy of surgical management in young infants.
Main Methods:
- Retrospective analysis of 36 infants diagnosed with choledochal cysts.
- Data collected included clinical presentation, laboratory findings, and surgical outcomes.
- Infants were categorized by age: <12 months (28) and 13-24 months (8).
Main Results:
- Cystic type choledochal cysts were most common.
- Typical symptoms included abdominal mass, jaundice, and acholic stools.
- Low bile amylase levels were noted despite pancreaticobiliary malunion; other pancreatic enzymes were elevated.
- Surgical treatment (cyst excision and biliary reconstruction) yielded favorable outcomes.
Conclusions:
- Choledochal cysts in infants present with characteristic signs and symptoms.
- Surgical intervention is the preferred treatment and is safe for infants, including those under 12 months.
- Management should address associated pancreaticobiliary malunion and enzyme profiles.
Abstract:
Thirty-six infants with choledochal cyst consisting of 28 babies less than 12 months of age and 8 between 13 and 24 months of age, were analyzed. Characteristics of cases were as follows: (1) they were usually of the cystic type, (2) a huge abdominal mass and jaundice with alcoholic stool were typically found, (3) no symptom suggesting acute pancreatitis was observed, (4) amylase levels in bile were usually low, despite the presence of pancreatobiliary malunion, while other pancreatic enzymes in bile commonly showed a high concentration, and (5) primary cyst excision and biliary reconstruction was the treatment of choice, and could be safely performed with favorable outcomes even in babies less than 1 year of age.
