ABSTRACT
The pilonidal sinus is a little frequent benign affection with often sacrococcygeal localization and that the etiopathologenesis is still debated. It affects mainly the young male adult. The diagnosis is generally easy in the typical forms: purulent discharge by an orifice located in the inter gluteal furrow and containing hairs. The authors suggest the analysis of the clinic and therapeutic aspects of the pilonidal sinus through a study spread over 9 years [January 1996-December 2004] and concerns 105 cases of pilonidal sinus with sacrococcygeal localization. The study is based on cases and operative reports in the register of proctology in the department. In our series, the chronic form of the pilonidal fistula represents 53, 7% whereas the acute form of abscess represents only 46,25% of all consultations. The pilonidal sinus may be associated to other protolo-gical affections. The open exeresis procedure was the only method used in our series, it is easy and effective method. Generally, the results were satisfying, the rate of recurrence was about 2,5% with minimal recession about 4 months. The only disadvantage is the long period of cicatrisation [6 weeks on average in our series]
