Objective To compare and analyze the clinical effect of aboral drainage skin-bridge sparing surgery and anal fistulotomy in the treatment of complex anal fistula. Methods Sixty cases of patients with complex anal fistula were selected as the research object, and divided into experimental group and control group equally. Control group un-derwent anal fistulotomy, and experimental group was treated with aboral drainage skin-bridge sparing surgery. Cure rate, healing time and postoperative anal function of two groups were compared. Results Wexner scores of post opera-tion, post-healing and 6 months follow-up in experimental group were lower than control group, and there was signifi-cant difference between two groups (P< 0.05); Cure rate in experimental group was higher than that in control group (86.7% vs 63.3%, P < 0.05); Cure time of experimental group was significantly shorter than that of control group [(22.5±4.6)d vs (31.4±4.7)d, P<0.05]. Conclusion Aboral drainage skin-bridge sparing surgery can preserve anal func-tion commendably, shorten operation time and improve cure rate, therefore it deserves clinical promotion for the treat-ment of complex anal fistula.%目的：比较分析对口引流保留皮桥术与肛瘘切开术治疗复杂性肛瘘的临床疗效。方法选取60例复杂性肛瘘患者作为研究对象,均分为实验组和对照组,对照组行肛瘘切开术,实验组行对口引流保留皮桥术,比较两组治愈率、治愈时间及术后肛门功能。结果实验组手术后、痊愈后及6个月随访Wexner评分均低于对照组,比较均有显著性差异(P<0.05)；实验组治愈率为86.7%,对照组为63.3%,实验组治愈率高于对照组(P<0.05)；实验组治愈时间为(22.5±4.6)d,对照组为(31.4±4.7)d,实验组治愈时间少于对照组(P<0.05)。结论采用对口引流保留皮桥术治疗复杂性肛瘘能很好地保留肛门功能,缩短手术时间,提高治愈率,值得在临床上推广。
