Professional Med J Jan ;16(1):17-23.

Objectives: To study the prevalence of pilonidal sinus and compare the outcome of the excision and primary closure with lay open surgical procedures. Design: Prospective randomized comparative study. Setting: Department of surgery, Bahawal Victoria Hospital Bahawalpur. Period: From 1st December 2002 to 30th November 2007.Materials and Methods: 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. Results: Patients of Group I & 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. Conclusion: We conclude that primary closure after excision of pilonidal sinus is superior surgical procedure than excision and laying it open.
