Brief Summary
Anal abscess-fistula disease is of common occurrence and has a significant impact on the quality of life of affected individuals. The course of abscess-fistula disease as well as its treatment modalities may affect anal continence. The present cohort study investigates the results of anal fistula plug surgery. In particular, this study focus on the impact of anal fistula plug surgery on fistula healing, quality of life, and anal continence. Fifty patients will be included and followed up at 6 weeks and 6 months after surgery in the clinic of participating surgeons.

Outcome Measures
Primary Outcomes (3)
Fistula healing
Clinical healing of a complex anal fistula as assessed in the clinic at 6 weeks and 6 months after anal fistula plug surgery. Further assessment prn.

Quality of life
Evaluation of health-related quality of life by means of a validated questionnaire, namely the Short-Form 36 version 2, at 6 weeks and 6 months after anal fistula plug surgery.

Anal fistula plug
EXPERIMENTALInterventions
All patients have a draining seton for at least 6 weeks prior placement of the anal fistula plug. All patients are administered a general anesthetic and are operated in the lithotomy position. The seton is removed, but no curettage or irrigation of the fistula tract is performed. The plug is inserted through the internal opening, and pulled through the external opening until it fit snugly and its base is sutured to the internal sphincter with 2 interrupted 2-0 polyglactin 910 sutures. The tip of the plug is cut at skin level and not sutured. The external opening is left open to allow for drainage. The patient is instructed to restrict physical and sexual activity for 2 weeks postoperatively. Patients are seen in the post-operative clinic at 10 days, 6 weeks and 6 months as per protocol.
