Abstract

Deep pancreatic cannulation (DPC) failure during endoscopic retrograde cholangiopancreatography (ERCP) in patients with chronic pancreatitis (CP) can occur in the presence of ductal obstruction due to strictures and/or stones. There are currently no simple preprocedure clinical or laboratory tests that can predict DPC failure during ERCP. Methods All adult patients with definite CP by M-ANNHEIM criteria referred to the pancreatitis clinic between 2010 and 2017 were evaluated. Serum trypsin levels were obtained to assess the morphologic severity of disease and/or exocrine insufficiency. Univariable and multivariable logistic regression analyses were performed to identify factors associated with DPC failure. Results There were 346 patients, of whom 100 underwent trypsin measurements and ERCP for symptomatic CP. Deep pancreatic cannulation failure occurred in 32 (32%). There were no significant differences with regard to age, sex, etiology, smoking, and alcohol use. Deep pancreatic cannulation failure was more likely to occur in patients with low trypsin levels (53.1% vs 25%, P = 0.007) compared with those with successful DPC. Low trypsin levels were independently associated with DPC failure in adjusted analysis (odds ratio, 3.7; 95% confidence interval, 1.2-11; P = 0.02). Conclusions Low serum trypsin levels independently predict DPC failure during ERCP in patients with symptomatic obstructive CP.
