Excision with Z-plasty in pilonidal sinus

ABSTRACT

To measure the outcome of the pilonidal sinus exicision with Z-plasty in terms of postoperative hospital stay, recurrence, wound infection and patient's time off work. Cross sectional study. Department of General Surgery, Ward-26, Jinnah Postgraduate Medical Centre Karachi, from January 2008 to January 2009. Patients with pilonidal sinus above 12 years of age were included in this study. They were diagnosed clinically. Those with abscesses and recurrence of disease were excluded. A total of 40 patients were operated. There were 28 [72%] males and 12 [28%] females. Majority were in the age group of 21 - 30 years [64%]. The operating time ranged between 30-45 minutes [mean 35 + 2]. Mean postoperative stay was 3.5 days [2- 5 days] and return to work was between 7-18 days [mean 12.5 days]. Three patients [7.5%] patients developed wound dehiscence, 6 [15%] had wound infection and recurrence occurred in 2 [5%]. 95% confidence interval[C.I] of overall complication was 13.4-40.1. Excision of pilonidal sinus followed by primary closure with Z-plasty technique had the advantage of early wound healing, short postoperative stay and low risk of recurrence
