Pilonidal cysts are a painful condition that primarily affect young adult men. In the literature, numerous operative techniques for resolving pilonidal cysts are described, with variable outcomes. The objective of this study was to compare primarily closed midline incisions managed with or without the use of closed incision negative pressure therapy after pilonidal cyst excision.
Twenty-one patients underwent excision and midline primary closure. Postoperative care composed of closed incisional negative pressure therapy (study group; n = 10) or gauze dressings (control group; n = 11). In both groups, the sutures were partially removed on day 14 and completely removed on day 21. Compared outcomes included the duration of hospitalization, pain on the day of surgical procedure, and on postoperative day 7, and time-to-healing.
The median hospital stay was about 9 hours and 23 hours in the study and control groups, respectively ( < 0.05). The median pain scores on the day of operation were 1.20/10 in the study group and 3.36/10 in the control group ( < 0.05). On day 7, study group showed median pain score 0.9/10 and control group showed 2.63/10 ( < 0.05). The mean healing time was 23.8 and 57.9 days in the ciNPT group and gauze group, respectively ( < 0.05).
These outcomes supported the incorporation of closed incision negative pressure therapy into our surgical treatment protocol for pilonidal cysts.
藏毛囊肿是一种主要影响年轻成年男性的疼痛性疾病。文献中描述了多种用于解决藏毛囊肿的手术技术，其结果各不相同。本研究的目的是比较藏毛囊肿切除术后采用或不采用闭合切口负压疗法处理的中线闭合切口。
21例患者接受了切除及中线一期缝合。术后护理包括闭合切口负压疗法（研究组；n = 10）或纱布敷料（对照组；n = 11）。两组均在第14天部分拆除缝线，第21天完全拆除缝线。比较的结果包括住院时间、手术当天及术后第7天的疼痛情况以及愈合时间。
研究组和对照组的中位住院时间分别约为9小时和23小时（<0.05）。手术当天研究组的中位疼痛评分为1.20/10，对照组为3.36/10（<0.05）。第7天，研究组中位疼痛评分为0.9/10，对照组为2.63/10（<0.05）。闭合切口负压疗法组和纱布组的平均愈合时间分别为23.8天和57.9天（<0.05）。
这些结果支持将闭合切口负压疗法纳入我们的藏毛囊肿手术治疗方案。
