Packing of Perianal Abscess Cavities Trial: A Randomised Multicentre Trial Comparing Packing With Non-packing of the Abscess Cavity

Packing of Perianal Abscess Cavities (PPAC) Trial: A Randomised Multicentre Trial Comparing Packing With Non-packing of the Abscess Cavity

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.

Inclusion Criteria:

• Clinical diagnosis of acute primary perianal abscess
• Have undergone surgical incision and drainage as an emergency

Exclusion Criteria:

• The abscess is the sequelae of concurrent disease or trauma
• Fourniers gangrene is suspected
• Unable to give informed consent
