Summary
This study presents two pediatric cases of choledochal cysts, a rare congenital condition causing bile duct dilation. Anomalous pancreaticobiliary junction was identified as a key factor in the etiology of these choledochal cysts.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Medical Imaging
Background:
- Choledochal cysts are congenital dilations of the biliary tree, often presenting in childhood.
- Type I choledochal cysts involve cystic dilation of the common bile duct.
- Recurrent abdominal pain is a common, though sometimes vague, presenting symptom in pediatric patients.
Observation:
- Two female Saudi pediatric patients with Type I choledochal cysts were analyzed.
- Symptoms included prolonged recurrent abdominal pain without jaundice or palpable masses.
- Imaging revealed cystic masses separate from the gallbladder, without intra-hepatic duct dilation; gallstones were noted in one patient.
Findings:
- Sonography and computed tomography (CT) accurately identified the cystic dilation and its location.
- Intraoperative cholangiography confirmed the presence of anomalous pancreaticobiliary junction (APBJ).
- APBJ is a significant risk factor implicated in the development of choledochal cysts.
Implications:
- Early diagnosis and surgical intervention are crucial for managing pediatric choledochal cysts.
- Understanding the role of APBJ aids in risk assessment and surgical planning.
- This case series highlights diagnostic approaches and etiological factors in Saudi pediatric patients.
