Short-and long-term results with Karydaki's technique for sacrococcygeal pilonidal diseaseIntroduction: Sacrococcygeal pilonidal cyst or sinus is a common condition in young people. There is still discussion about which of the many existing techniques is best suited to resolve this condition. Objective: To analyze the short-and long-term use of Karydaki's technique in our Hospital. Material and Methods: We analyzed prospective protocols from patients with pilonidal cyst with Karydaki's technique from June 2005 to August 2010. Clinical and telephonic follow-up was done to all patients and a satisfaction survey done to a random sample of the series. Results: We analyzed 62 patients with mean age of 24.5 years (15-45), being 33 men (53%). Cysts were previously relapsed in 20.9% of cases. The average hospital stay was 2.5 days (1-3). Early complications occurred in 14.3% of patients being the most common seroma in 8% and dehiscence in 6.4%. At a mean follow up of 38 months (12-62), relapse occurred in two patients (3.2%), one at 6 months and the other at 3 years, being resolved one by a new Karydaki's technique and the other with marsupialization. Among the group surveyed for satisfaction, 75% found the technique satisfactory or very satisfactory in terms of aesthetics and 95% would recommend this technique. Conclusions: Karydaki's operation achieves with a simple and aesthetic technic a low recurrence and morbidity and a complete recovery after 15 days in most patients.
