Abstract
AIM: To explore the rule of pancreaticobiliary disease displayed by endoscopic retrograde cholangiapancreatography (ERCP).
METHODS: Retrospective analysis of 190 patients underwent ERCP from May 1 to August 30, 2004 was performed at Changhai hospital. Three contents including amorphology of the biliary tree, influential factors for dilated biliary tree and the correlations with pancreaticobiliary disease were studied.
RESULTS: Of the 190 patients, examination was not completed in 4 cases, and 38 were found without intact bile tree and 148 with intact one. All the 148 patients were classified into 7 groups: Normal bile tree was observed in 18 patients with chronic pancreatitis or without biliopancreatic disease; Hibernated bile tree was found in 15 patients with choledocholithiasis, in whom the mean values of common bile duct (CBD) and stones were 1.41 ± 0.25 and 0.69 ± 0.22 cm in diameter, respectively; Willow-like bile tree was found in 56 patients with choloedocholithiasis, in whom the mean values of CBD and stones were 1.69 ± 0.39 and 1.32 ± 0.44 cm in diameter, respectively; Sapless bile tree was found in 36 patients with choledocholithiasis, in whom the mean values of CBD and stones diameter were 1.80 ± 0.47 and 1.33 ± 0.46 cm in diameter, respectively; Vine-like bile tree was detected in 17 patients with endobiliary cholangiocarcinoma of CBD and carcinoma of pancreatic head, in whom the mean values of CBD diameter was 2.35 ± 0.62 cm; Irregular bile tree was in 6 patients without dominant disease.
CONCLUSION: The morphology of bile tree is associated with biliopancreatic disease and its features. The degrees of dilated CBD were resulted from the location and nature of the disease.
