Pilonidal sinus

ABSTRACT

Pilonidal sinus is a frequent benign disease, with a localization often sacrococcygeal. Its etiopathogensis is still badly clarified. Diagnosis is generally easy in typical forms purulent flow by an opening situated at the level of inter gluteal furrow and containing some hairs. Some diagnosis traps secondary to aberrant localizations should be known. Open surgical excision and cicatrizationnn is the treatment of choice. To this effect, we report 29 cases of pilonidal sinus operated on by this method between 1990 and 1999. This pathology occupies the fourth place of proctological diseases 75% of the patients are young, aged between 20 and 40 years. Male predominance is clear with a sex ratio H/F=1,9. Chronic purulent flow is the main symptom found in 82,23 of cases. After a retreat of one to 10 years, a case of fake recurrence has been noted. A second resection without closure has been successfully done
