Modification of the Bascom cleft lift procedure for chronic pilonidal sinus: results in 141 patients.

AIM: There is no definitive consensus on the best treatment for pilonidal sinus. The Bascom cleft lift technique has been reported to produce successful results. This study presents the results of a modified cleft lift procedure in which the sinus tissue was excised and the lower end of the incision was kept outside the intergluteal sulcus by extending the lower end of the incision laterally.

METHOD: Between August 2010 and January 2012, 141 consecutive patients who presented with primary or recurrent pilonidal sinus disease were included in the study, which was conducted at a single tertiary academic medical centre. Prospectively collected data were recorded, including complications, pain score, satisfaction level, primary healing rate, length of hospital stay and early recurrence.

RESULTS

The mean operating time was 30 min and the mean length of hospital stay was 1.2 days. The most common surgical-site complication was a collection followed by partial wound dehiscence and superficial infection. The primary healing rate was 88%, the mean time for functional recovery was 13 days and the mean follow-up time was 14 months. No recurrence was observed within this follow-up period.

CONCLUSION

The modified Bascom cleft lift technique is effective and reliable. It is applicable to all pilonidal sinus cases and has low complication rates, high satisfaction scores, rapid early recovery and low recurrence rates.
