Abstract：
BACKGROUND: Pilonidal disease (PD) is a common condition for which the global incidence is increasing. Surgery is the currently preferred approach to treatment but there is a growing interest in new minimally invasive techniques, such as sinus laser therapy (SiLaT).
OBJECTIVE: Our primary objective was to assess the efficacy of SiLaT for the treatment of pilonidal disease. The secondary objectives were to evaluate morbidity and patient satisfaction and identify predictive factors of success.
METHODS: All adult patients, who underwent SiLaT in our department for a primary or recurrent pilonidal sinus from June 1, 2018, to December 31, 2020, were included in the study. Healing was defined as the closure of cutaneous orifices and the absence of seepage or abscesses.
RESULTS: In total, 111 consecutive patients, for whom the male/female sex ratio was 2.1 and the mean age 28.8 (± 9.4) years, were included in this study. Eighteen (16.2%) patients had already undergone prior surgery for PD. The mean follow-up was 339.2 (± 221.4) days. A healing rate of 78.4% was observed, with a median time to healing of 20.0 days (15.0-30.0). The median time to return to usual activities was three days (1-7). The only postoperative complication was bleeding, which occurred for two patients (1.8%). Eighty-two patients (88.2%) reported being \"very satisfied\" with the treatment. Multivariate analysis showed no predictive factors for healing among the studied variables.
CONCLUSIONS: SiLaT is an efficient and safe procedure for the treatment of PD, with a high level of patient satisfaction. It will now be necessary to position it within the therapeutic algorithm.

摘要：
背景：人皮病（PD）是一种常见病，其全球发病率正在增加。手术是目前首选的治疗方法，但人们对新的微创技术越来越感兴趣。如鼻窦激光治疗（SiLaT）。
目的：我们的主要目的是评估SiLaT治疗藏毛疾病的疗效。次要目标是评估发病率和患者满意度，并确定成功的预测因素。
方法：所有成年患者，从2018年6月1日至2020年12月31日在我们部门接受SiLaT治疗原发性或复发性藏毛窦的患者被纳入研究.愈合被定义为关闭皮肤孔和没有渗漏或脓肿。
结果：总计，111名连续患者，男女性别比例为2.1，平均年龄为28.8(±9.4)岁，包括在这项研究中。18例（16.2％）患者已经接受了PD手术。平均随访339.2(±221.4)天。观察到78.4%的治愈率,中位愈合时间为20.0天（15.0-30.0）。恢复正常活动的中位时间为3天(1-7)。术后唯一的并发症是出血,2例患者（1.8%）。82名患者（88.2％）报告对治疗“非常满意”。多变量分析显示，在研究变量中没有治愈的预测因素。
结论：SiLaT是治疗PD的一种有效且安全的方法，患者满意度高。现在有必要将其定位在治疗算法内。
