Outcome Measures

Primary Outcomes (2)

  • Fistula Healing rate at 3 months

    Healing of fistula as evidenced by MRI of the ano-rectum.

    3 months

  • Fistula Healing Rate at 12 months

    This will be assessed by a telephonic questionnaire at 12 months following intervention

    12 months

Secondary Outcomes (4)

  • Complication rate

    12 months

  • Faecal Incontinence questionnaire (Wexner)

    At recruitment, 7-10 days, 6 weeks and 6 months

  • Faecal Incontinence quality of life questionnaire (FIQL)

    At recruitment, 7-10 days, 6 weeks and 6 months

  • Pain Score

    At recruitment, 7-10 days, 6 weeks and 6 months

Study Arms (1)

Collagen paste

EXPERIMENTAL

Injection of Permacol Collagen paste into the fistula tract.

Biological: Collagen paste

Interventions

Collagen pasteBIOLOGICAL

Permacol cross-linked collagen paste, 2.5-3.5 mls to be injected into the MRI defined fistula tracts 7-10 days following drainage of the anorectal abscess.
