| Decomprssion and drainage seton | Procedure | Incision the internal sphincter over the fistula tract in intersphinteric space to achieve decompression then drainage seton will be put around external sphincter. |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of healing | complete healing was defined as complete epithelialization of the wound, with no evidence of external fistula opening or perianal discharge under physical examination. | 6 months post-operation. |
| Recurrence rate | recurrence was defined as the clinical reappearance of the fistula after complete healing, removal or fall-off of seton | within 12 months after the procedure |
| The healing time of the anal wound (days) | the time needed to achieve complete healing of anal fistula. | 6 months post-operation. |
