目的研究血栓性外痔改良切除术对血栓性外痔手术后减轻水肿、疼痛的疗效。方法多中心、随机试验。治疗组、对照组各60例,治疗组采用血栓性外痔剥离切除加对侧减压切口,术毕扩肛的治疗方法。对照组采用传统剥离切除术。观察两组术后第2天、第4天、6天及出院时水肿、疼痛情况,并予评分量化比较。结果术后第2天、第4天、第6天及出院时治疗组水肿积分均明显低于对照组(P<0.01),差异有显著意义,术后第2天、第4天治疗组疼痛积分明显低于对照组(P<0.01),自第6天起疼痛积分两组无差别。结论血栓性外痔改良切除术能减轻术后水肿和肛周疼痛。
Objective To study the effect of thrombotic external hemorrhoidectomy on edema and pain relief after thrombotic external hemorrhoids operation. Methods Multi-center, randomized trial.

Results The scores of edema of the treatment group on the 2nd, 4th, 6th day and after discharge were significantly lower than those of the control group (P <0.01), and the difference was significant. The pain of the treatment group on the 2nd and 4th postoperative day The score was significantly lower than that of the control group (P <0.01).
