目的：探讨不同类型乳头旁憩室与胰胆疾病之间的关系以及对内镜下逆行胰胆管造影（ＥＲＣＰ）插管成功率的影响。方法：回顾分析本院１９９４～１９９６年进行ＥＲＣＰ检查的１４２２例患者（１２７例有乳头旁憩室，１２９５例无憩室）的内镜下表现、插管情况及最终诊断。结果：有憩室组总插管显影１２６例，胰胆管显影１００例，选择性插管失败３例。有憩室组插管后显影的１２６例中有胆胰系统疾病者９６例（７６．２％），无憩室组阳性发现３５５例（２７．４％），两组比较有显著差异（Ｐ＜０．００１）；其中胆管结石和胆管癌的发现率明显高于无憩室组，不同乳头旁憩室组间各种疾病发现率无差异。结论：憩室的存在可能和某些胰胆疾病的发生有关，而不同类型乳头旁憩室间胰胆疾病的发生无显著差异，乳头旁憩室在一定情况下并不影响插管成功率
Objective: To investigate the relationship between different types of papillary diverticula and pancreaticobiliary diseases and the success rate of endoscopic retrograde cholangiopancreatography (ERCP) intubation. Methods: A retrospective analysis of our hospital from 1994 to 1996 ERCP examination of 1422 patients (127 cases of papillary diverticulum, 1295 cases of diverticula) endoscopic performance, intubation and final diagnosis. Results: There were 126 cases of total intubation in the diverticulum group, 100 cases of pancreaticobiliary ductal development and 3 cases of selective intubation failure. There were 96 cases (76.2%) of patients with diverticula after intubation and 126 cases of diseases with biliary and pancreatic diseases, and 355 cases (27.4%) of patients without diverticula. There was significant difference between the two groups (P <0 .001). The detection rate of bile duct stones and cholangiocarcinoma was significantly higher than that of non-diverticulum group, and there was no difference in the detection rate of various diseases between different papillary diverticula groups. Conclusions: The presence of diverticula may be related to the occurrence of some pancreaticobiliary diseases. However, there is no significant difference in the occurrence of pancreaticobiliary diseases between different types of papillary diverticulum. The papillary diverticula under certain circumstances does not affect the success rate of intubation
