Abstract

We carried out a systematic review of the literature to identify the association between the use of drain and the incidence of infections and recurrences after surgery. MEDLINE, SCOPUS and ISI databases were searched up to September 2012. The two outcomes of this meta-analysis were wound infection and recurrence. Postoperative wound infection occurred in 50 of the 604 (8.28 %) patients who underwent drainage and in 68 of the 598 (11.4 %) patients who did not, with a resulting odds ratio (OR) of 0.71 (95 % CI: 0.48-1.03). Recurrence of pilonidal sinus occurred in 41 of the 604 (6.79 %) patients who underwent drainage and in 50 of the 598 (8.36 %) patients who did not, with a resulting OR of 0.80 (95 % CI: 0.52-1.23). The results suggest that, despite a trend toward a reduction in infectious complications and recurrence, drainage was not associated with a better outcome. However, because of the present literature's limitations, further studies are needed to address this issue.
