To study the prevalence of pilonidal sinus and compare the outcome of the excision and primary closure with lay open surgical procedures. Prospective randomized comparative study. Department of surgery, Bahawal Victoria Hospital Bahawalpur. From 1st December 2002 to 30th November 2007. A total of 40 patients with pilonidal sinus were randomized into two groups. Group I underwent excision and primary closure while Group II underwent excision and lay open procedure. Patients of Group I and II had comparable mean operation time of 42.7 minutes. Group I patients had a shorter mean hospital stay of 4.87 days, earlier return to light work after 13.21 days, less treatment expenses and low rate of postoperative complications and good patient satisfaction. We conclude that primary closure after excision of pilonidal sinus is superior surgical procedure than excision and laying it open
