Abstract:
Objective To investigate the incidence of occult pancreatobiliary reflux and to evaluate its relation to gallbladder epithelial dysplasia and cancer. Methods From July 2006 to Feb 2008,956 cases underwent selective biliary procedure or preoperative endoscopic retrograde cholangiopanereatography (ERCP), bile was collected and amylase was measured. All removed gallbladders were pathologically examined for dysplasia and cancer. Results Occult pancreatobihary reflux was found in 75 of 754 patients in this study, with an incidence of 9. 9%. The biliary amylase values in the patients with occult pancreatobiliary reflux and in controls were 7701±20 378 IU/L and 16±51 IU/L, respectively ( P <0. 01 ).Gallbladder dysplasia and cancer were found in 31.0% and 3.4% of the patients with occult pancreatobiliaryreflux, respectively, and both were higher than those in the patients without pancreatobiliary reflux ( P <0. 05). In the patients with occult pancreatobiliary reflux, the biliary amylase level with gallbladder dysplasia or cancer was 2388 ± 2745 IU/L and was higher than those without gallbladder dysplasia or cancer (P < 0. 01 ). Conclusions With an incidence of 9.9% in patients of normal pancreatobiliary junction,the occult pancreatobihary reflux may contribute to the pathogenesis of gallbladder epithelial dysplasia and cancer.
