肛门内括约肌部分切开术在混合痔外剥内扎术中的应用

目的探讨外剥内扎注射术加肛门内括约肌部分切开术治疗混合痔的临床疗效。方法2010年1月-2012年1月间搜集诊断明确，并住院行手术治疗且符合纳入标准的混合痔患者，分成观察组（184例）和对照组（180例），两组均行外剥内扎注射术，其中观察组加肛管后侧部分切开肛门内括约肌，观察比较两组患者术后疼痛、创口水肿、出血及创口愈合时间及肛门狭窄等并发症情况。结果两组患者术后疼痛时间、并发症发生率、住院时间等比较，差异有统计学意义（P〈0．01）。结论外剥内扎注射术加肛管后侧部分切开肛门内括约肌治疗混合痔可有效缓解术后症状，减少并发症，缩短疗程，是合理、可行的术式，值得临床推广。

Clinical Study of External Dissection and Internal Ligation,Plus Partial Internal Sphincterotomy in the Treatment of Mixed Hemorrhoids

Objective To investigate the effect of external dissection and internal ligation, plus partial internal sphincterotomy in the treatment of mixed hemorrhoids. Methods During January 2010 to January 2012, 364 patients with mixed hemorrhoids selected for surgery were divided into two groups based on whether the patients should accept the treatment of partial internal sphincterotomy. We observed the curative effect of the two groups, including anal pain, bleeding, edema, average healing days and the anorectal stenosis after operation. Results There were statistical differences between the two groups in terms of anal pain, complication rate and hospital stay （P 〈 0.01）. The curative effect of the group treated with partial internal sphincterotomy was better than that of the other group. Condustion External dissection and internal ligation, plus partial internal sphincterotomy is a better choice in the treatment of mixed hemorrhoids, which can relieve postoperative symptoms, reduce complications and shorten treatment course.
