Infection of anal glands leads to abscess formation which spread in the inter-sphincteric planes. The initial routine treatment is incision, drainage and curettage, but the most frequent complication regarding this phenomenon is abscess recurrence and subsequent fistula in Ano formation. Objective: To determine the frequency of fistula in Ano (FIA) after incision and drainage of perianal abscesses.Material and Method: This Descriptive case series study was conducted at Department of surgery, MTI lady Reading Hospital Peshawar, from Jan, 2017 to 2019, on total of 170 patients of perianal abscess, treated initially with incision and drainage, under general anesthesia. Monthly follow-up for six months was scheduled for any complication specially developing Fistula in Ano.Results: In the current study mean age was 36 years ±10.28. Seventy-two patients were male and 28% patients were female. 2 Mean BMI was 25Kg/m . Fistula in Ano among 170 patients was developed in n=73(43%) patients. Mostly in an age group of 41years to 50 years and with longer duration of symptoms.
