Brief Summary:
The aim of this study is to compare the effect of packing and non-packing on the healing rate of perianal abscess cavities. Secondary objectives are to assess quality of life, cost effectiveness and rate of abscess recurrence and fistula-in-ano formation. If there is no difference in time to healing and non-packing is shown to be safe, acceptable to the patient and cost effective, this approach may become more widely accepted.

Primary Outcome Measures :
  1. Time to wound healing in days, defined as complete epithelialisation of the abscess cavity. [ Time Frame: 1 day to 6 weeks ]
    time to healing will be assessed in days


Secondary Outcome Measures :
  1. Quality of life scores as determined by the Euro QoL EQ-5D-3L [ Time Frame: 10 to 14 days ]
    Quality of life scores as determined by the Euro QoL EQ-5D-3L will be measured at 10-14 days following incision and drainage of abscess


Other Outcome Measures:
  1. Abscess recurrence rate [ Time Frame: 0 days to 12 months ]
  2. Fistula-in-ano formation rate [ Time Frame: 0 days to 18 months ]
  3. Cost [ Time Frame: 0 days to 18 months ]
