Cases treated by incision and thread drawing with 1 recurred(average healing time 20.22±5.24 days); 32 cases by incision suture plus internal opening drainage with 3 recurred(average healing time 22.84±6.66 days); 34 cases by fistulectomy and primary suture with 5 recurred( average healing time 25.56 ±7.51 days);32 cases by fistulotomy with 6 recurred(average healing time 30.43±10.72 days).

结果：随访5～10个月(平均7 2个月)，切开挂线术37例，复发1例，平均愈合时间(20 22±5 24)d；切缝内口引流术32例，复发3例，平均愈合时间(22 84±6 66)d；瘘管摘除缝合术34例，复发5例，平均愈合时间(25 56±7 51)d；瘘管旷置术32例，复发6例，平均愈合时间(30 43±10 72)d。

Low complex anal fistula usually can be treated by incisionsuture plus interal opening drainage or fistulectomy and primary suture, and high complex anal fistula by incision and thread drawing or fistulotomy.
