This study was done to compare the efficacy of closed Vs open haemorrhoidectomy. The study design was unblinded randomised control trial at Dhulikhel Hospital, Kathmandu University Hospital. Total number of patients was 56 all with 3rd and 4th degree haemorrhoids. Post operative pain was taken as main outcome measures. Operation time varied from 200 seconds for each haemorroidal cushion with open technique to 626 seconds by closed technique. The blood loss was not quantifiable in closed technique. Pain was scored on visual analogue scale. In closed group, the pain score was 4.9 immediate post operative period and 2.3 (24 hours later). In the other group, the scores were 7.8 and 6.9. These differences were significant. At the end of study we came to a conclusion that haemorrhoidectomy using closed technique has more advantages.
本研究旨在比较闭合式与开放式痔切除术的疗效。该研究设计为在加德满都大学医院杜利凯尔医院进行的非盲随机对照试验。患者总数为56例，均患有Ⅲ度和Ⅳ度痔疮。术后疼痛作为主要观察指标。手术时间从开放式技术每个痔垫200秒到闭合式技术626秒不等。闭合式技术的失血量无法量化。疼痛采用视觉模拟评分法进行评分。在闭合组，术后即刻疼痛评分为4.9，24小时后为2.3。另一组的评分分别为7.8和6.9。这些差异具有统计学意义。在研究结束时，我们得出结论，采用闭合式技术的痔切除术具有更多优势。
