目的探讨经内镜序贯植入双金属支架治疗胆道并十二指肠恶性梗阻的临床疗效。方法回顾性分析9例胆道并十二指肠恶性梗阻患者经内镜植入金属双支架,其中2例同时序贯植入十二指肠支架及胆道支架,2例先行植入胆道支架,出现十二指肠梗阻后再植入十二指肠支架,5例先行植入十二指肠支架,狭窄段扩张后再植入胆道支架,其中2例通过肠道支架网眼植入胆道支架。结果该组9例恶性胆道梗阻患者经内镜放置金属十二指肠支架及胆道支架均获成功,成功率100.0%,总有效率88.9%。结论经内镜植入金属胆道支架及金属肠道支架对胆道恶性梗阻并十二指肠恶性梗阻,引流减黄效果明确,解除消化道梗阻,能提高生活质量、延长生存期;但此类操作对术者操作技巧要求高,建议在大型内镜中心完成。
Objective To investigate the clinical efficacy of sequential implantation of bimetallic stents by endoscopy in the treatment of malignant biliary duodenal obstruction. Methods Nine patients with malignant biliary tract and duodenal obstruction were enrolled in this study. Metal double stent was implanted by endoscopy, of which 2 cases were simultaneously implanted with duodenal stent and biliary stent, and 2 cases were initially implanted with biliary stent. Duodenal obstruction and then implanted duodenal stent, 5 cases first implanted duodenal stent, expansion of the stenosis segment and then implanted into the biliary stent, of which 2 cases were implanted through the intestinal stent mesh biliary stent. Results Nine patients with malignant biliary obstruction were successfully treated by endoscopic placement of metal duodenal stent and biliary stent. The success rate was 100.0% and the total effective rate was 88.9%. Conclusion The endoscopic implantation of metal biliary stent and metal intestinal stent for malignant biliary obstruction and malignant duodenal obstruction, drainage clear yellow effect, relieve gastrointestinal obstruction, can improve quality of life and prolong survival; However, such operations Operational skills of the surgeon demanding, it is recommended to complete the large endoscopic center.
