Aim: Pilonidal disease is generally located at sacrococcygeal region whereas it is rarely located near anus. Patients and Methods: Patients admitted between to with sinuses located in 2 cm range of anus or were primarily located up to 2 cm to the anal verge were enrolled in the study.
Crystallized phenol was applied into the sinus. The pa tients were followed-up after recovery during the first 6 months and annually afterwards. Results: A total of 25 sinus pilonidalis cases located near anus were encountered. All patients were male; crystallized phenol application was per formed on all patients a total of times.
The mean number of applications was 5. The mean recovery period was No surgical intervention was required. Conclusion: Sinus pilonidalis cases located in perianal region can be successfully treated with the crystallized phenol application which is a simple and inexpensive method, that can easily be performed in an outpatient setting. Most of the reported sinus pilonidalis cases are found in the sacrococcygeal region.
In few cases, tracks run towards the caudal direction and may open lateral or even anterior of the anus [], and cause confusion in the diagnosis and treatment. The differential diagnosis should include perianal fistula.
After exclusion of the fistula, surgical treatment is the generally preferred choice of treatment. Despite the successful results of new techniques, some complex cases such as patients with secondary openings away from the midline can lead some problems. Total subcutaneous fistulectomy plus Karydakis flap, developed by Kulacoglu et al. Although successful results have been reported, surgical intervention in this region has always been a challenge under these circumstances.
