Arm Intervention/treatment
Experimental: decomprssion and drainage seton Procedure: Decomprssion and drainage seton
Incision the internal sphincter over the fistula tract in intersphinteric space to achieve decompression then drainage seton will be put around external sphincter.

Active Comparator: Cutting seton Procedure: Cutting seton
Cutting seton is introduced from outside openning to internal openning and encircling the internal and external anal sphincter.

Primary Outcome Measures :
  1. Rate of healing [ Time Frame: 6 months post-operation. ]
    complete healing was defined as complete epithelialization of the wound, with no evidence of external fistula opening or perianal discharge under physical examination.

  2. Recurrence rate [ Time Frame: within 12 months after the procedure ]
    recurrence was defined as the clinical reappearance of the fistula after complete healing, removal or fall-off of seton

  3. The healing time of the anal wound (days) [ Time Frame: 6 months post-operation. ]
    the time needed to achieve complete healing of anal fistula.
