等离子前列腺电切系统在直肠瘢痕性狭窄治疗中的应用

Application of plasma prostate electrovaporization system in the treatment of rectal cicatricial stenosis

目的探讨等离子前列腺电切系统治疗直肠瘢痕性狭窄的操作技巧、可行性和临床疗效。方法用类似经尿道前列腺电切的方法对7例直肠癌治疗后（行经腹腔低前切除术5例，三维适形精确放疗2例）出现的低位瘢痕性直肠狭窄患者行直肠内瘢痕切除术，以扩大肠腔、解除梗阻。结果7例患者共行12例次手术，其中行1次手术者3例，行2次手术者3例，3次手术者1例。切除直肠瘢痕组织约5～15g／例，手术时间平均41（25-50）min，手术成功率100％，无穿孔、出血、感染等并发症的发生。术后患者均顺利排便。结论等离子前列腺电切系统治疗直肠瘢痕性狭窄创伤小、疗效确切。

Objective To evaluate the feasibility, maneuver and efficacy of plasma prostate electrovaporization system in the treatment of rectal cicatricial stenosis. Methods According to similar procedure of transurethral resection prostate （TURP）, intrarectal cicatriclectomy was performed with plasma prostate electrovaporization system in 7 patients with rectal low cicatricial stenosis after rectal cancer treatment （5 patients with transabdominal low anterior resection,2 patients with 3-dimension precise radiotherapy） to remove obstruction and dilate enteric cavity. Results Seven patients underwent 12 operations, including one operation in 3 patients, two operations in 3 patients, 3 operations in one patient. Resected rectal cicatricial tissue ranged from 5 to 15 g. Mean operation time was 41 min（25 to 40）. Operation successful rate was 100% without complications such as perforation, bleeding and infection. All the patients had smooth defecation. Conclusion Plasma prostate electrovaporization system is an effective treatment for rectal cicatricial stenosis with tiny trauma.
