ABSTRACT
This study was conducted to evaluate Karydakis technique for the management of chronic pilonidal sinus in obese patients. The study included 40 patients divided according to their body mass index [BMI] into two groups: Group I included obese patients and Group II included non-obese patients. There was no significant difference between obese and non-obese patients regarding their clinical presentation in terms of symptoms, duration of the disease and number of sinus openings. It was concluded that Karydakis technique for management of chronic pilonidal sinus was easy to perform, had a fast healing time, short hospital stay and low recurrence rate. The results were similar between obese and non-obese patients with a BMI< 30.5 and no recurrence seen in these patients. Complications occurred in obese patients had a BMI > 30.5. In such patients, a dietary regimen before operation was advisable and inserting a suction drain during the operation was recommended to avoid seroma formation
