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.
我们对文献进行了系统的回顾，以确定引流与手术后感染和复发之间的关联。检索了 MEDLINE、SCOPUS 和 ISI 数据库，截至 2012 年 9 月。这项荟萃分析的两个结果是伤口感染和复发。接受引流的 604 名患者中有 50 名（8.28%）发生术后伤口感染，未接受引流的 598 名患者中有 68 名（11.4%）发生术后伤口感染，由此产生的比值比（OR）为 0.71（95%CI：0.48-1.03）。接受引流的 604 名患者中有 41 名（6.79%）发生皮瓣窦复发，未接受引流的 598 名患者中有 50 名（8.36%）发生皮瓣窦复发，由此产生的 OR 为 0.80（95%CI：0.52-1.23）。结果表明，尽管引流有降低感染性并发症和复发的趋势，但与更好的结果无关。然而，由于目前文献的局限性，需要进一步的研究来解决这个问题。
