Abstract:
BACKGROUND/AIMS: This study was designed to evaluate normal Korean pancreaticobiliary ducts and to assess the prevalence and pattern of variations and anomalies of theses structures. METHODS: We performed this multicenter study in which 7 university hospitals in Korea participated from March 1997 until June 1999. Total 10,243 ERCP cases were reviewed during this study period. RESULTS: 1) Maximal and midportion diameters of common bile ducts were 6.4+/-1.8 mm and 5.5+/-1.7 mm, respectively. Maximal and midportion diameters of pancreas head were 3.2+/-1.1 mm and 2.7+/-1.0 mm, respectively. Pancreaticobiliary duct diameters of subjects above the age of 40 were greater than those of subjects below the age of 40 (p<0.05). 2) The prevalence of choledochal cyst was 0.32%. The prevalence of gallbladder anomalies and anomalous union of pancreaticobiliary duct was 4.2% and 4.1%, respectively. The prevalence of pancreas divisum and annular pancreas was 0.49% and 0.05%, respectively. The most common type of pancreaticobiliary duct union was V shape (60.2%), followed by U shape (23.7%) and Y shape (16.1%). CONCLUSIONS: Understanding normal pancreaticobiliary structures and being aware of the prevalence and pattern of variations and anomalies of pancreaticobiliary structures will be helpful to diagnose and treat patients with pancreaticobiliary problems.
