Description

Infection of the anal sac to form an abscess and it may follow from anal sac impaction. Fistulous tracts may arise from the abscess and rupture to the skin.

Diagnosis

History and Clinical Signs

  • See Anal Sac Disease - General
  • Will also see a discharging sinus or a perianal mass
  • Microscopic examination of the fluid will show polymorphonuclear leukocytes and bacteria

Treatment

Incision of the sacs and drainage plus lavage with an isotonic solution or 0.05% chlorhexidine. The incisions should be left open and broad spectrum systemic antibiotics given until results of culture and sensitivity are back. Common organisms are Escherichia coli, Streptococcus faecalis and Proteus species. If the condition becomes chronic, it is best managed by an anal sacculectomy.
