Abstract: Objective To investigate the clinical effects on Millagan-Morgan procedure combined with SETUS-M in the treatment of Ⅲ°and Ⅳ°mixed hemorrhoids. Methods From January 2006 to January 2009,180 cases with Ⅲ°and Ⅳ°mixed hemorrhoids were randomly divided into two groups,namely experimental group and control group. The Millagan-Morgan procedure combined with SETUS-M were used in 90 cases of experimental group. Only Millagan-Morgan procedure was used in 90 cases of control group. The observation and comparison were performed between two groups, including postoperative painful time, frequency in the use of analgetic, postoperative bleeding, swelling time of surface of wound, complications, hospitalization time,recovering normal time of work and life and adverse reaction of drug. Results In the comparidon between experimental group and control group, the former was shorter than that latter in the postoperative painful time, swelling time of surface of wound, hospitalization time and recovering normal time of surface of wound(P<0.05), postoperative bleeding was decreased significantly(P<0.01) and postoperative complications were declined significantly(P<0.05).But the postoperative urinary retension was no obvious difference(P>0.05).In the experimental group, no adverse reaction was found in taking SETUS-M period. Conclusion Millagan-Morgan procedure combined with SETUS-M is a cheap, safe,and effective therapeutic method for the treatment of Ⅲ°and Ⅳ°mixed hemorrhoids.

摘要： 目的 探讨Millagan-Morgan术（以下简称M-M术）联合消脱止-M治疗Ⅲ°Ⅳ°混合痔的临床疗效。方法 将180例Ⅲ°Ⅳ°混合痔患者随机分为两组，试验组90例采用M-M术联合消脱止-M，对照组90例只用M-M术。观察和比较两组患者手术时间、术后疼痛时间、应用镇痛药频率、术后出血、创面肿胀时间、并发症情况、住院时间、恢复正常工作生活时间、用药不良反应等指标。结果 试验组与对照组相比，术后疼痛时间、创面肿胀时间、住院时间、恢复正常工作和生活时间明显缩短（P＜0.05），术后出血量明显减少（P＜0.01），术后并发症发生率明显下降（P＜0.05），但手术时间、术后尿潴留差异无显著性意义（P＞0.05）。治疗组服用消脱止-M期间无不良反应。结论 M-M术联合消脱止-M是治疗Ⅲ°Ⅳ°混合痔的一种经济、安全、有效的治疗方法，尤适合基层医院应用。
