Aim Of This Study:
to report our results in a large series of patients with chronic pilonidal sinus (PS) at long term follow up.
Materials And Methods:
Two hundred sixteen patients underwent excision and rhomboid flap transposition (RFT) from 1986 to 2004 for PS, and followed for more than two years. Clinical presentation includes: pilonidal abscess treated by drainage (33%), chronic discharge (48%) and simple infected sinus (19%). Mean follow-up was 74.4 months (range: 24-96).
Results:
Minimal flap necrosis occurred in 5 pts (2.3%), post operative infection in 2 pts (0.9%), 4 pts (1.8%) had a seroma, 18 pts (8.3%) anesthesia or hypoesthesia on the upper portion of the flap. The mean hospitalization was 3.1 +/- 0.30 days and return to work was 10.8 +/- 2.4 days. Recurrences occurred in 5 pts (7.4%) in our initial 87 pts. Since we modified the technique no recurrences were seen.
Conclusions:
The Limberg's technique is a very effective procedure for chronic or recurrent PS with a low complications rate, a short hospital stay, a rapid return to normal activities and a low recurrence rate. Moreover with the modified technique the wound healing and the rate of recurrences have shown a significant decrease.
