近日，宜宾市第五人民医院内镜中心成功开展内镜食管静脉曲张套扎术（EVL）、食管胃底静脉曲张组织胶及硬化剂注入术（EIS+ EVHT）和食管癌术后狭窄行胃管下食管扩张术三项新技术，实现了技术突破与成本降低，同时手术的成功实施，减少了患者医疗费用，且达到了治愈的效果，让南溪及其周边的群众“足不出区”即能享受到优质的消化内镜医疗服务。
新技术1
内镜下食管静脉曲张套扎术（endoscopic esophageal varix ligation，EVL），是指在内镜的引导下，用弹性橡胶圈结扎曲张的静脉根部，使其缺血、坏死、脱落，使曲张静脉闭锁，可有效控制活动性曲张静脉出血，并可快速消除静脉曲张。其原理类似痔疮橡皮圈结扎法。是一种安全、有效、简单的食管静脉曲张破裂出血止血和预防出血的治疗方法。对于急诊或择期治疗食管静脉曲张患者有明显效果。
适应症
1.门静脉高压食管胃静脉曲张出血，紧急止血者。
2.门静脉高压食管胃静脉曲张(一级、二级预防)，失去外科手术机会或不愿接受外科手术者。
3.中、重度食管静脉曲张虽无出血但有明显的出血危险倾向。
4.既往有食管静脉曲张破裂出血史。
5.胃静脉曲张有红色征或表面糜烂且有出血史。
新技术2
食管胃静脉曲张硬化治疗术（EIS)+组织胶注射治疗术（EVHT）是一种在内镜的辅助下，通过注射硬化剂与组织胶，阻塞血管，增强止血效果，具有创伤性小、操作简便等优点。
硬化治疗术（EIS）
作用机制：硬化剂注入静脉内损伤血管内皮，局部形成无菌性炎症，白细胞浸润，使静脉壁增厚，静脉腔变窄或闭塞，使静脉曲张减轻或消失。
组织胶注入术（EVHT）
作用机制：组织胶是一种快速固化的水样物质，静脉注射后与血液接触发生聚合反应和硬化，能有效闭塞血管和控制曲张静脉出血。
新技术3
内镜下食管狭窄扩张术
主要适用于各种原因引起的食管狭窄（如恶性肿瘤、术后吻合口瘢痕、其他原因引起的食管狭窄等）。该技术无创伤，见效快，术后即可正常进食，大大地缩短了住院时间，减少治疗费用，能够轻松解决患者吃饭哽咽、吞咽困难等问题。食管狭窄扩张术，是目前公认的治疗食管良性狭窄的首选方法，食管狭窄扩张术简便易行，痛苦小，术后恢复快，通过扩张球囊或者其他扩张器对食管进行机械性扩张。
适应症：
1.各种病因导致的消化道非活动性炎性狭窄者；
2.术后吻合消化道口狭窄者；
3.贲门失弛缓症；
4.消化道瘢痕性狭窄者；
5.消化道发育异常者；
6.异物或结石引起的狭窄。
