内镜下推进式放射状切开术治疗良性食管狭窄的疗效观察（含视频）

Curative effect of endoscopic push-radial dissection for patients with benign esophageal stricture （with video）

目的探讨内镜下推进式放射状切开术（EPRD）治疗良性食管狭窄的可行性及疗效。方法选择24例确诊为良性食管狭窄患者在狭窄处沿食管纵轴放射状切开狭窄处瘢痕至浅肌层，观察手术情况及治疗效果。结果24例患者均成功接受EPRD治疗，手术时间15～45min，平均32min，切开狭窄段长度1．0—8．0cm，平均3．2cm，无一例出现与内镜治疗相关的严重并发症，无一例转外科手术。术后随访1～5个月，平均2．8个月，23例患者吞咽困难明显缓解，内镜通过顺畅；1例患者术后2周出现吞咽困难复发，予再次EPRD及支架置人术，术后症状缓解。结论EPRD治疗良性食管狭窄相对安全可行，具有一定的疗效。

Objective To evaluate the feasibility and efficacy of endoscopic push-radial dissection （EPRD） for benign esophageal stricture （BES）. Methods Clinical data of 24 patients diagnosed as having BES who received EPRD were analyzed. The procedure and efficacy were evaluated. Results All 24 patients underwent EPRD successfully with mean operation time being 32 min（ 15-45 min）.The mean esophageal stricture incision length was 3.2 cm （ 1.0-8. 0 cm）.No severe complications related to EPRD occurred, or transferred for surgery. Patients were followed up for 1-5 months （mean 2. 8 months）. Dysphagia was relieved significantly during the follow-up in 23 patients where endoscopy could go through smoothly. But dysphagia re-occurred in one patient 2 weeks after the operation, who underwent a second EPRD and stent implantation, then dysphagia was relieved. Conclusion EPRD is safe, feasible and effective for benign esophageal stricture.
