Characteristics of choledocal cyst patients in Bandung, Indonesia : single centre experience

Introduction: Choledochal cyst (CC) is a congenital cystic dilation of bile duct. Although considered a benign disor- der, but CC has various complications like cholangitis, cholelithiasis, pancreatitis and malignant degeneration. The characteristic of this malformation are still not well documented in our region. We aimed to describe the characteris- tic of CC patients in Hasan Sadikin Hospital Bandung, Indonesia. Method: The medical records of patients that were diagnosed with CC between 2014 and 2017 were reviewed. We retrospectively collected demographic data, clinical symptoms, diagnostic imaging and surgical data. Results: Fifteen patients were diagnosed as CC, predominantly were girls (12 patients). The mean age was 63,47 months old (range from 7 to 144 months). Jaundic was found in all patients, followed by abdominal pain in 12 patients (80%) and abdominal mass in 9 patients (60%). The laboratory results showed signs of bile obstruction in 5 patients (33,3%). Diagnostic imaging using ultrasonography revealed 5 patients (33,3%) with CC type IV, whereas type I in 6 patients (40%). MRI was performed in 8 patients (53,3%) and CT Scan was performed in 5 patient (33,3%). Eleven patients (73,3%) underwent cyst excision and Roux-en-Y hepaticojejunostomy with liver biopsy. Conclusion: Our data suggested that CC predominantly found in girls, and abdominal pain was the most common symptom. Ultrasonography, MRI, and CT are imaging modalities use to diag- nose CC. Surgical treatment should be done includes total cyst excision dan biliodigestive reconstruction
