Outcome of Fistula in Ano after Incision Drainage of Acute Peri Anal Abscess

OBJECTIVES: To determine outcome of fistula in ano after incision drainage of acute peri anal abscess. METHODOLOGY: This descriptive case series study was conducted after approval of the Ethical committee. A total of 154 patients were observed for a six-month duration. Pre-design proforma was used to collect data. An inclusive criterion was age between 18-50 years of both genders with acute perianal abscess with low-level fistula (submucosal and mucocutaneous) and high-level fistula (ischiorectal and pelvirectal). Exclusive criterion was observed in all admitted patients who include secondary abscess formation for example diabetes mellitus, tuberculosis, and carcinoma with any previous history of fistula in ano. The result was analyzed through the SPSS-24 version. RESULTS: Ratio 35 (22.72%) was obtained for age group 18-30, 49 (31.81%) for age group 31-40 and 70 (45.44%) were in age group 41-50. The mean age was 38.25 years with SD ±9.70. The ratio of Males 143 (92.85%) leads high to females 11 (7.15%). The fistula was found in 64 (41.55%) patients postoperative after incision drainage for perianal abscess. Among 64 patients, 54 (37.01%) were male and 7 (4.54%) females. 90 (58.44%) patients had no fistula postoperatively. Low-level 45 (29.22%) and 19 (12.33%) high-level fistula was found in patients. Among the low-level ratio, 40 were male and 5 were female. Similarly, in high-level fistula 17 were male and 2 were female. CONCLUSION: Fistula is more common in males than females. Low lying fistula leads the chart more than a high lying fistula. The incidence of anal fistula in our observed patient’s abscess was 41.55%.
