内括约肌部分切断对减轻嵌顿痔术后疼痛的临床观察

Clinical Observation on Partial Incision Internal Sphincter for Reducing Pain after Operation for Circular Incarcerated Hemorrhoids

目的观察内括约肌部分切断对预防及减少嵌顿痔外剥内扎术后疼痛的临床效果。方法将90例环状嵌顿痔患者随机分为治疗组及对照组,每组各45例。治疗组采用外剥内扎加部分内括约肌切断术,对照组单纯采用外剥内扎术,术后3h、24h及第一次解大便时作疼痛对比研究。结果治疗组对减少术后疼痛明显优于对照组(P<0.01)。结论外剥内扎加部分内括约肌切断术可明显减轻嵌顿痔术后疼痛及相应并发症,疗效确切。

Objective：To observe the curative effects of preventing and reducing pain after operation for cir cular incarcerated hemorrhoids by partial incision internal sphincter. Methods： Ninety patients with circular incarcerated hemorrhoids were randomly assigned into study group （45 cases） and controlled group （45 ca ses）. The former received external dissection and internal ligation plus partial incision internal sphincter, the latter was received only external dissection and internal ligation. Pain was recorded at 3 hours, 24 hours and the first stool after operation. Results：The study group had less pain than the controlled group. Conclusion：External dissection and internal ligation plus partial incision internal sphincter can significantly decrease pain and complications after operation for circular incarcerated hemorrhoids.
