内镜黏膜下剥离术治疗食管肿瘤的临床价值

目的 探讨内镜黏膜下剥离术(endoscopic submucosal dissection,ESD)在食管肿瘤治疗中的价值.方法 利用染色内镜及超声内镜探测病变范围及侵犯深度,对位于黏膜层及黏膜肌层的早期癌、癌前病变、黏膜下肿瘤等病变行ESD治疗.于病灶边缘2 mm处用氩气刀标记切除范围,于病灶及周围黏膜下注射甘油果糖使病变与固有肌层相分离;沿标记线外侧切开病变周围黏膜;剥离病变下方黏膜下层组织,完整切除病变.结果 21例病灶,最大直径均大于2 cm,病灶最大者直径5 cm.8例早期食管黏膜内癌,5例食管黏膜中、重度异型增生及8例食管平滑肌瘤经ESD-次性完全切除.ESD手术时间30～180 min,平均110 min;术中少量出血均经电凝止血;术后无迟发性出血发生;1例早期食管癌术中发生穿孔(4.76%),经内镜金属夹封闭、内科保守治疗后痊愈.术后随访1～12个月无复发.结论 在超声内镜及色素内镜的指导下,采用内镜黏膜下剥离术治疗食管黏膜内癌、癌前病变及黏膜肌层的肿瘤,是一项安全有效的内镜治疗方法.

Clinical value of endoscopic submucosal dissection for esophageal tumors

Objective To investigate the value of endoscopic submucosal dissection (ESD) in treatment of esophageal tumors. Methods The properties,range and infiltrating depth of the neoplastic lesions in esophagus were detected by chromoendoscopy and endoscopic ultrasonography. The mucosal lesions including early cancers,submucosal tumors deriving from mucosa were removed by ESD: injecting fructose-glycerol fluid into the submucosa to elevate the lesion from the muscle layer,pre-cutting the surrounding mucosa of the l...
