Patients Undergoing Surgery for Pilonidal Sinus in the Department of Surgery in a Tertiary Care Centre: A Descriptive Cross-sectional Study

Introduction: Pilonidal sinus refers to a condition that results when hair penetrates the natal cleft skin, leading to granuloma formation and induces secondary infection and abscess formation. This study aims to find the prevalence of patients undergoing surgery for pilonidal sinus out of total surgeries performed in the Department of Surgery at a tertiary care centre. Methods: This descriptive cross-sectional study was conducted among patients with pilonidal sinus at a tertiary care hospital from 16 July 2021 to 14 June 2022 after obtaining ethical approval from the institutional review committee and was conducted retrospectively from 01 March 2022 to 30 June 2022 using medical records. All patients who underwent surgery in the Department of Surgery during the specified period were included in the study, with entries containing missing data being excluded. A convenience sampling method was used. The point estimate was calculated at a 95% confidence interval. Results: Among 1812 patients undergoing surgery, 30 (1.66%) (1.07-2.24, 95% Confidence Interval) patients had undergone surgery for pilonidal sinus. Among them, 26 (86.67%) were male patients, while 4 (13.33%) were female patients. Conclusions: The prevalence of patients undergoing surgery for pilonidal sinus is found to be similar to other studies in similar settings.
