鼻窦病（PNSD）挑战了外科医生数十年。Limberg皮瓣修复术（LFR）是PNSD的常用治疗方法。目的观察LFR在PNSD中的作用及危险因素。对2016年至2022年在解放军总医院2个医疗中心和4个科室就诊并接受LFR治疗的PNSD患者进行回顾性研究。风险因素,手术的效果，观察并发症。比较已知危险因素对手术结果的影响。有37名PNSD患者：男女比例为35：2，平均年龄：25.1±7.9岁。平均BMI：25.2±4.0kg/m2，平均创面愈合时间：15.4±3.4天。术后1期愈合30例（81.0%），7期愈合（16.3%）。只有1例患者（2.7％）复发，而其他患者则在换药后治愈。在年龄上没有显著差异,BMI,术前清创史,术前窦房结分类,伤口区域,负压引流管,易发时间(<3d)和治疗效果。深蹲排便和过早排便与治疗效果相关,在多变量分析中,它们是治疗效果的独立预测因子.LFR具有稳定的治疗结果。与其他皮瓣相比，这种皮瓣的治疗效果没有显着差异，但设计简单，不受手术前已知危险因素的影响。然而,有必要避免两个独立风险因素的影响，蹲便和过早排便,关于治疗效果。
Pilonidal sinus disease (PNSD) challenged surgeons for decades. Limberg flap repair (LFR) is a common treatment for PNSD. The purpose of this study was to observe the effect and risk factors of LFR in PNSD. A retrospective study was conducted on the PNSD patients who visited two medical centers and four departments in the People\'s Liberation Army General Hospital and were taking LFR treatment between 2016 and 2022. The risk factors, the effect of the operation, and complications were observed. The effects of known risk factors on the surgical results were compared. There were 37 PNSD patients: male/female ratio of 35:2, average age: 25.1 ± 7.9 years. Average BMI: 25.2 ± 4.0 kg/m2 , average wound healing time: 15.4 ± 3.4 days. 30 patients (81.0%) healed in stage one and 7 (16.3%) had postoperative complications. Only 1 patient (2.7%) had a recurrence while others were healed after dressing-changing. There was no significant difference in age, BMI, preoperative debridement history, preoperative sinus classification, Wound area, Negative pressure drainage tube, prone time (<3d) and treatment effect. Squat defecate and premature defecation were associated with treatment effect, and they were independent predictors of treatment effect in the multivariate analysis. LFR has a stable therapeutic outcome. Compared with other skin flaps, the therapeutic effect of this flap is not significantly different, but the design is simple and is not affected by the known risk factors before operation. However, it is necessary to avoid the influence of two independent risk factors, squatting defecation and premature defecation, on the therapeutic effect.
