Objective: To investigate the results of rhomboid excision and the Limberg flap procedure to treat pilonidal sinus disease.

Method: The records of 411 patients with pilonidal sinus disease, who underwent rhomboid excision and Limberg flap procedure, were analysed. All sinus tracks were resected en bloc, and a Limberg flap was prepared from left or right gluteal region. A suction drain was routinely used.

Results: The mean follow-up period was 109.2 +/- 4.5 months (range: 12-183 months). Recurrence occurred in 12 (2.91%) patients who were all male. In 42 (10.21%) patients, anaesthesia or hypoaesthesia of the upper portion of the flap occurred; this was temporary in 25 patients. Twelve (2.91%) patients developed a seroma and 15 (3.64%) a wound infection. The average hospital stay was 3.2 days (range: 1-10 days), and the average time of return to work was 12.4 days (range: 7-18 days). The average time to walk without pain was 13.4 days (range: 10-28 days) and the average time to sitting on the toilet without pain was 16.1 days (range: 12-28 days).

Conclusion: The Limberg flap procedure is effective and has a low complication rate, short time for returning to normal activity and short hospitalization.
