use of gentamicin beads in the treatment of pilonidal sinus

ABSTRACT

This study included 47 patients with pilonidal sinus, divided into two groups. The first group included 32 patients treated by surgical excision and primary closure of the wound on "gentamicin beads" which were withdrawn, one bead every day, starting from the second post operative day. The second [control] group formed of 15 patients, was treated by complete surgical excision, primary closure of the wound on a continuos negative suction drainage, intra and post-operative systemic gentamicin antibiotics for days. Sound healing was achieved in about 97% of our patients of the first group in 10 to 15 days, while only about 3% of the patients developed recurrence. In the control group our patients passed smooth post operative period with sound healing of their wounds in 2-3 week. Minor would infection occurred in 13.3%, major wound infection 6.7% and recurrence of the sinus in 6.7% of our patients. Our method of treatment adopted for patients of the first group is simple, effective and applicable for all forms of pilonidal sinus, with minimal recurrence rate, reasonable hospital stay period, healing time and minimal discomfort to patients
