Frequency and severity of post-ERCP pancreatitis correlated with extent of pancreatic ductal opacification.

摘要: Background Pancreatitis is the most common complication of diagnostic and therapeutic ERCP. Almost certainly, etiology this pancreatitis multifactorial. Objective The primary objective study was to evaluate relationship between extent pancreatic ductal opacification frequency pancreatitis. Design Retrospective study. Setting ERCP database at our institution searched for prospectively collected data from 1994 2005. Patients Interventions A total 14,331 ERCPs were included in analysis. divided into 4 groups according duct opacification: group 1, no attempted or failed cannulation (n = 6739); 2, head only 845); 3, body 2061); 4, tail 4685). incidence severity compared within each group. Results overall rate 4.0%. There a progressively higher with increased system ( P 65 years), sex, type procedure performed (diagnostic therapeutic) not significantly different beyond opacification. Multivariate analysis showed that suspected sphincter Oddi dysfunction manometry independent predictors post-ERCP Conclusions Less filling associated less Before performing endoscopic retrograde pancreatography, endoscopists should carefully whether any pancreatogram what needed clinically. Greater use noninvasive pancreatography decrease
