目的 比较三种术式治疗多次发作肛瘘的临床疗效。方法 选取2013-05 至 2014-05本院收治的多次(≥3次)发作的脓肿性肛瘘患者240例，按入院顺序编号，分组为A(编号3N-2)、B(编号3N-1)、C(编号3N)组，1≤N≤80，且为整数;每组各80例;A组患者行肛瘘切除一期缝合术，B组患者行肛瘘切除基底缝合术，C组患者行肛瘘切除半深缝合术，对比各组患者术后各项资料进行统计分析。结果 C组有效率高达98.75%，且无后遗症，术后平均恢复时间最短为6.5 d，且瘢痕平均宽度最窄为3.5 mm;B组效果次之，A组效果最差。3组有效率比较，差异有统计学意义(P＜0.05)。结论 肛瘘切除半深缝合术对多次发作的肛瘘患者疗效最优。

Objective To compare the clinical efficacy of three kinds of surgical treatment for multi-episode anal fistula.Methods 240 patients with anal abscess fistula admitted in this hospital from May 2013 to May 2014 treated over three times were recruited. They were divided, according to admission order, into flu group A (coded no. 3 N-2) group B (coded no. 3 N-1) group C (coded no. 3 N), 80 patients in each group. Group A underwent anal fistula resection with stage I suture and group B received basal decompression anal fistula resection. Group C were subjected to anal fistula resection and half deep suture technique. Statistical analysis of all postoperative information was carried out in the groups of patients.Results The efficacy in Group C was as high as 98.75%, and no sequela, the average postoperative recovery time was shortest 6.5 d, and the scar average width the most narrow is 3.5 mm. Effect in group B was inferior, group A worst.Conclusions The clinical curative effect of anal fistula resection and half deep suture technique for multi-episode patients is the optimal.
