Abstract Review of elective procedures for pilonidal disease in a single centre, Jan 2020 – Aug 2021 Introduction Pilonidal disease continues to be managed with a variety of surgical techniques. We review results with Bascom 2 operation comparing to other practices at our institution. Method All elective procedures for pilonidal disease reviewed from Jan 2020 to August 2021. Age, gender, previous emergency and elective procedures for pilonidal disease, follow-up, recurrence and dehiscence rates, all-cause morbidity was examined retrospectively. Results In the study period there were 44 procedures. Average age was 26.4 years (range 16–44). Male to female ratio was 2:1. Procedure techniques performed included modified Bascoms flap (20), excision and primary closure (20), excision and packing (3) and Rhomboid flap (1). The number of previous emergency and elective procedures in the cohort were 18 and 3 respectively. In 24 (55%) procedures there was documented follow up, at a mean time of 49 days (median 56 days, range 3–84). Overall modified Bascom dehiscence (partial / full) dehiscence and recurrence rates were 10% and 5% respectively. Overall median number of bed related days length of stay was 0 days (range 0–3 days). Conclusions The modified Bascoms procedure is both technically simple and reproducible and offers comparatively good dehiscence and recurrence rates relative to other pilonidal sinus procedures.
