Management of perianal sepsis in a district general hospital.

Perianal sepsis remains a common surgical problem. A total of 121 patients undergoing surgery for perianal abscess and/or fistulae over a 2-year period was studied. Of these, 50 patients (41.3%) had suffered from previous perianal sepsis (not necessarily resulting in hospital attendance). Ninety-one patients underwent incision and drainage of abscesses (ischiorectal and perianal) for the first time, whereas eight patients underwent drainage of recurrent abscesses. Fistulae were identified when the abscess was drained in 14 of 91 patients, and a further ten patients subsequently developed fistulae. Twenty-two patients presented with a discharging fistula. A high yield of bowel organisms was present in patients with coexisting fistulae (88%), recurrent abscesses (75%) and in those who subsequently developed fistulae (83%). We confirm that such a growth can be used to identify patients who will benefit from further examinations.
