Modified Limberg’s Transposition flap for pilonidal sinus: long term follow up of 216 cases
Main Article Content
Abstract
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.
