肛瘘术后复发危险因素分析

Risk factors for recurrence after anal fistula surgery

目的 探讨肛瘘术后复发的危险因素.方法 2010年7月至2010年12月收治腺源性肛瘘手术患者963例,随访到906例,对随访的患者资料进行复发危险因素分析.结果 随访12 ～18个月,复发51例,总复发率5.6％.单因素分析显示复发与肛瘘分型、肛瘘位置、存在脓液、内口位置有关.多因素分析显示复发与肛瘘分型、肛瘘高低、存在脓液有关.结论 高位复杂肛瘘、肛瘘伴有脓液术后复发率较高,识别手术复发相关的危险因素对于减少复发有重要意义.

Objective To assess risk factors for anal fistula recurrence.Methods The records of 963 patients who underwent surgery for anal fistula between July 2010 and December 2010 in Beijing Rectum Hospital were retrospectively reviewed and 906 of them were followed up.Risk factors associated with recurrence were analyzed by using univariate and multivariate regression methods.Results Based on the observation for 12 to 18 months,51 patients（5.6％）had recurrence.Risk factors associated with recurrence in univariate analysis included fistula type,fistula location,associated liquor puris and location of internal fistulous opening.Risk factors associated with recurrence in multivariate analysis included fistula type,high anal fistula and associated liquor puris.Conclusion High complex anal fistula and fistula with liquor puris had a higher recurrence rate.Identification of the risk factors associated with recurrence is important for reducing recurrence.
