摘要目的 探讨内镜下十二指肠乳头预切术在恶性胆道梗阻诊治中的应用价值.方法 对46例插管困难的恶性胆道梗阻患者,根据十二指肠乳头及其周围结构、插管情况等采用不同预切方法对乳头括约肌施行内镜下预切术,观察ERCP诊治的完成情况,以及并发症发生情况.结果 应用弓形刀切开法4例、针状刀切开法24例、经胰管胆管切开法12例、联合方法6例,其中35例预切术后胆管插管成功,成功率达76.1%(35/46).发生术后黏膜渗血3例、胰腺炎1例、高淀粉酶血症2例、胆管炎1例,未见穿孔发生.结论 内镜下乳头预切术可提高恶性胆道梗阻患者ERCP诊治的成功率,且适时、正确地应用可以降低并发症的发生率.

abstractsObjective To evaluate the endoscopic precut sphincterotomy for malignant biliary obstruction. Methods Endoscopic precut sphincterotomy was performed in different ways for 46 patients with malignant biliary obstruction and difficult biliary cannulation according to the anatomic structure of the papilla and cannulation. Ways of precut were summarized and complications were analyzed. Results Precut sphincterotomy was performed with bow-like knife in 4 patients, with needle-knife in 24, with trans-pancreatic sphincterotomy in 12 and with combined ways in 6. The procedure succeeded in 35 cases (76. 1%, 35/46). Post-procedure complications included bleeding in 3 patients, pancreatitis in 1, hyper-amylasemia in 2and cholangitis in 1. No perforation was found. Conclusion Endoscopic precut sphincterotomy is not only able to improve the therapeutic endoscopy achievement rate in patients with malignant biliary obstruction, but also to lower the incidence of complications if used adequately.
