Original Study


Objective The present work was designed to compare a VY flap and a rhombiod flap in the treatment of pilonidal sinus. Background The pilonidal sinus is a tract that usually contains hair. It occurs under the skin between the buttocks (the natal cleft) a short distance above the anus. The sinus track traverses in a vertical direction between the buttocks. Rarely, a pilonidal sinus occurs in other sites of the body such as the axilla, groin, interdigital webs, or the feet. The exact cause is not clear. There are various theories. For example, one theory states that the problem may develop from a minor congenital or hereditary abnormality in the skin of the natal cleft, in which the hair grows into the skin rather than outwards. Materials and methods We studied 30 patients aged 19-47 years (average, 30 ± 10 years) presenting to the outpatient clinic of El-Menoufia university hospital and El-Helal insurance hospital at Shebin El-Kom with pilonidal sinus from December 2012 and May 2013. The patients were followed up until July 2013. A total of 15 patients (50%) were treated with a VY flap and 15 (50%) were treated with a dufourmentel flap. Results The outcome was successful in 14 of 15 patients who received a VY flap and 15 of 15 patients who received a dufourmentel flap. The operative time is shorter in the VY method than the dufourmentel method (P < 0.05). Hospital stay was shorter in the dufourmentel group than the VY group. The duration of follow-up was 6 months in both groups. Recurrence developed in only one patient from the VY group. Excellent results were more commonly observed in younger patients. Conclusion Recovery following treatment with a dufourmentel flap is better than with the other method.
