Abstract: Objective This study accessed the clinical efficacy of skin location assisted endoscopic band ligation for grade Ⅱ-Ⅲ internal hemorrhoids. Methods A total of 70 consecutive patients diagnosed grate Ⅱ-Ⅲ internal hemorrhoids were enrolled in this study. The observation group（n=35） performed skin location assisted endoscopic band ligation and the control group（n=35） performed tradition hemorrhoids ligation. The age, gender and the classification of hemorrhoids for both groups were of no significant differences. The post operational pain, bleeding, other complications and effectiveness were observed and compared. Results The operative time and postoperative bleeding rate for both groups were of no significant difference. The post operational pain of the observation group was significantly lower than that of the control group, and the life quality for the observation group was significantly greater than that of the control group. The observation group had greater effective rate （97.14% vs 85.71%, P>0.05）, and fewer complication rate than the control group （5.71% vs 17.14%, P>0.05）but had no significant difference. Conclusions Skin location assisted EBL causes less postoperative pain and less complication than the traditional ligation group and is expected to be safe and effective for grade Ⅱ-Ⅲ internal hemorrhoids.

摘要： 目的 探讨体表标记定位内镜下内痔套扎治疗Ⅱ~Ⅲ度内痔的临床效果。方法 将70例Ⅱ~Ⅲ度内痔患者分成观察组和对照组,分别为35例。观察组采用精准体表定位内镜下痔套扎术治疗,对照组采用传统痔套扎术。比较两组患者术后疼痛、出血等并发症、临床效果等指标。结果 观察组和对照组的年龄、性别、痔分度等一般临床资料差异无统计学意义。观察组和对照组手术时间、术后出血发生率差异无统计学意义（P>0.05）。观察组术后疼痛视觉评分低于对照组,生活质量评分优于对照组,差异具有统计学意义（P<0.05）,观察组总体有效率97.14%,高于对照组的85.71%,并发症发生率5.71%,低于照组的17.14%,差异无统计学意义（P>0.05）。结论 体表精准定位内镜下痔套扎治疗Ⅱ~Ⅲ度内痔疗效确切,较传统痔套扎术疼痛更轻、并发症更少。
