透明帽在食管复杂异物取出术中的应用价值

目的探讨透明帽在食管复杂异物取出术中的有效性及安全性。方法回顾性分析2013年1月至2017年2月对91例食管复杂异物利用胃镜先端透明帽辅助异物钳夹取的方法，观察治疗异物取出时间、成功率、出血及穿孔等并发症的发生情况。结果本组91例均完成治疗，常规胃镜下取出13例，静脉麻醉下取出78例。异物取出操作时间约为8-57min，平均时间（15．6±5．7）min。11例有黏膜渗血，1例活动性出血，1例有深溃疡形成并伴有出血，未出现重大并发症，无外科手术发生，操作成功率100％。结论透明帽辅助胃镜下食管异物取出术可增加镜下可操作空间，缩短操作时间，减少医源性损伤，使操作更为有效及安全，具有较好的应用价值。

Objective To investigate the efficacy and safety of transparent cap in removal of complicated foreign body in esophagus. Methods 91 cases of esophageal foreign bodies by means of complex apex transparent cap foreign body forceps extraction were analyzed retrospectively from January 2013 to February 2017. The occurrence time, success rate, complications such as bleeding and perforation ofthe treatment to remove the foreign body were observed. Results 91 cases were all treated, 13 cases were removed under routine gastroscope, 78 cases were removed under intravenous anesthesia. The removal time of foreign body was about g ~ 57min, and the average time was 15.6 ＋_ 5.7rain. There were 11 cases with mucosal bleeding, 1 cases with active bleeding, 1 cases with deep ulcer, accompanied by bleeding, no major complications, no surgical operation, and the success rate was 100%. Conclusion Transparent cap assisted extraction of esophageal foreign body under endoscope can increase the operative space, shorten the operation time, reduce iatrogenic injury, make the operation more effective and safe, and has better application value.
