体外牙线牵引辅助内镜黏膜下剥离术治疗视野暴露困难的早期结直肠癌的效果

Effect of external floss traction assisted ESD in the treatment of early colorectal carcinoma with difficult visual field exposure

目的分析体外牙线牵引辅助内镜黏膜下剥离术(ESD)治疗视野暴露困难的早期结直肠癌的效果。方法选取2017年1月-2021年9月该院收治的常规ESD视野暴露困难的早期结直肠癌患者104例作为研究对象,采用随机数表法分为观察组和对照组,各52例,均给予ESD治疗,观察组术中辅助体外牙线牵引治疗,比较两组的临床治疗效果。结果观察组术中操作时间短于对照组,术中出血量、黏膜下补充注射量和黏膜下补充注射次数少于对照组,病灶完全切除率和整块切除率高于对照组,并发症总发生率低于对照组,差异均有统计学意义(P<0.05)。结论体外牙线牵引用于ESD治疗早期结直肠癌,能够提高病灶切除率,缩短手术操作时间,减少操作次数,降低并发症发生率。

Objective To analyze the effect of external floss traction assisted endoscopic submucosal dissection(ESD)in the treatment of early colorectal carcinoma with difficult visual field exposure.Methods 104 patients with early colorectal carcinoma who suffered from visual field difficulties due to conventional ESD exposure from January 2017 to September 2021 were taken as the research object.They were randomly divided into two groups,52 patients in each group.Both the observation group and the control group were given ESD treatment.The observation group assisted with external dental floss traction during the operation.The clinical application effects of the two groups were compared.Results The observation group had shorten intraoperative operation time compared to the control group,with less intraoperative bleeding,submucosal injection volume,and submucosal injection frequency,and the rate of complete resection and block resection were higher than those in the control group,and the total incidence of complications was lower than that in the control group,the differences were statistically significant(P<0.05).Conclusion External floss traction assisted ESD in the treatment of early colorectal carcinoma can improve the resection of the lesion,shorten the operation time and reduce the number of operations,and reduce the complications rates.
