Insights
Common bile duct dilatation (CBDD) is increasingly diagnosed in children. Early diagnosis via ultrasound and ERCP is crucial for effective treatment and management of these pancreaticobiliary disorders.
Area of Science:
- Pediatric Gastroenterology
- Hepatobiliary Surgery
- Diagnostic Imaging
Background:
- Common bile duct dilatation (CBDD) encompasses diverse pancreaticobiliary disorders with varied causes.
- Understanding the spectrum and management of CBDD in pediatric populations is essential.
Observation:
- Four pediatric cases (17 months–10 years) presented with abdominal pain and bilious vomiting; one had prior pancreatitis.
- Cholestatic jaundice was noted in only one patient.
- Diagnosis utilized ultrasound, confirmed by ERCP (3 cases) and CT (1 case).
Findings:
- Three patients had Type I choledochal cysts (fusiform extrahepatic dilation), treated with excision and Roux-en-Y hepaticojejunostomy.
- One patient had a Type IV cyst (intra- and extrahepatic dilation) with an anomalous pancreaticobiliary junction and distal obstruction, treated with transduodenal sphincterotomy.
Implications:
- An increasing incidence of CBDD in children is suggested.
- Ultrasound and ERCP are vital for diagnosing and visualizing pancreaticobiliary ducts.
- Treatment selection depends on CBDD type and associated anomalies.
Objectives:
Common bile duct dilatation (CBDD) represents part of a wide spectrum of pancreaticobiliary disorders, with different etiopathogenic mechanisms. The objective of this study was to compile the cases treated in our service during the last five years.
Patients And Methods:
Four cases of CBDD (17 months to 10 years of age) are reported. All of them presented abdominal pain and bilious vomiting. One patient previously had pancreatitis. Cholestatic jaundice was associated in only one patient. The diagnosis was made by ultrasound, being confirmed by endoscopic retrograde cholangiopancreatography (ERCP) in three cases and by computed tomography scan (CT) in one case.
Results:
Three patients had a single fusiform dilation of the extrahepatic bile duct (type I cyst, Alonso Lej-Todani classification), which were treated by cyst excision and hepaticojejunostomy by using a Roux-en-Y limb. In one patient, the ERCP detected a combined dilatation of the intra- and extrahepatic bile duct (type IV cyst), associated with an anomalous choledochopancreticoductal junction with a distal obstruction of the common bile duct. In the case, the treatment consisted of a transduodenal esfintherotomy.
Conclusions:
Based on our experience and a literature review, an increasing incidence of this pathology is deduce. Therefore, the relevance of ultrasounds and ERCP in the diagnosis and visualization of pancreatobiliary ducts and the choice of treatment, depending on the CBDD, are discussed.
