Abstract
Background: The pathogenesis of pilonidal sinus is not clearly understood. Evolution of epithelium-lined skin pits is currently believed to be the initial event. These are produced by widening of skin pores (of hair follicles and gland orifices) due to the combined effects of mechanical stretching and local infection Aim of Work: This is an attempt to focus on the etiology, pathology and surgical treatment of pilonidal disease; including solving technical and design factors that contribute to wound complications and recurrence. Patients and methods: This study included 30 patients with pilonidal sinus to all of them excision of the sinus with primary closure were done, 12 patients with Bascom’s technique, 11 patients with rhomboid flap and 7 patients with Karydakis technique. Results: The operative time and the hospital stay of Bascom’s technique was significantly less, there was no significant difference in postoperative wound seroma and infection between the three groups. On follow up for 6 months, recurrent sinus was the same in the three groups. Conclusions: Pilonidal sinus is an annoying disease and its surgical treatment are frequently unsatisfactory, Bascom’s technique is an easy operation to do, takes a shorter time with shorter hospital stay and smooth postoperative course with minimal wound sepsis. We recommended its application for most cases of pilonidal sinus.
