چکیده

Introduction Biliary cysts with an abnormal pancreatobiliary junction are one of the most common pancreatobiliary malformations. The main symptom is cholestasis; endoscopic retrograde cholangiopancreatography (ERCP) plays a key role in diagnosis. Aim Retrospective evaluation of ERCP performed to diagnose abnormalities of the pancreatobiliary junction. Material and methods We retrospectively evaluated ERCP performed to diagnose abnormalities of the pancreatobiliary junction, mainly choledochal cysts, in 112 children between 1990 and 2011. Results We performed 112 examinations of 50 children with abnormal pancreatobiliary junction and choledochal cysts (15 males and 35 females, average age: 5 years, range: 1 month - 15 years). Cysts were associated with a common channel in 37 (74%) cases, were not associated with a common channel in 9 (18%) cases, and in 3 (6%) cases the common channel lacked cysts. We performed endoscopic papilla sphincterotomy on 33 (66%) patients; endoscopic drainage was performed 62 times, including 17 patients without papilla sphincterotomy. In 15 (30%) cases, we only performed sphincterotomy. Extraction of lithiasis was done in 2 (4%) cases. Both ERCP and magnetic resonance cholangiopancreatography (MRCP) were performed on 13 patients. There was concordance of the choledochal cyst and of the type of cyst in both methods; however, common channels could not be observed by MRCP. There was 1 serious complication (perforation after sphincterotomy) and 11 (9%) mild adverse events. Conclusions When performed at an expert centre, ECRP is a safe and reliable procedure for children with choledochal cysts and/or an abnormal pancreatobiliary junction. Endoscopic retrograde cholangiopancreatography remains a reasonable alternative because MRCP has a limited ability to diagnose the precise anomalies of the pancreatobiliary junction and has no therapeutic capabilities.

We did not perform an endoscopic retrograde cholangiopancreatography because the diagnosis had been made on MRCP, and demonstration of APBDU could not have changed the management decision and could have ...

Recent advances in choledochal cysts

Choledochal cysts are a congenital anomaly, and they show dilatation of the intraor extrahepatic biliary tree. These cysts are uncommon in Western countries, but are not rare in Asian countries. Choledochal cysts are classified into five groups based on location or shape of the cysts. Types I and IV-A cysts are the most common types, which are associated with anomalous pancreaticobiliary juncti...
