BRAZILIAN AND ARGENTINEAN MULTICENTRIC STUDY IN THE SURGICAL MINIMALLY INVASIVE TREATMENT OF PILONIDAL CYST

ABSTRACT Background: The pilonidal cyst is an infection of the skin and the subcutaneous tissue, secondary to a chronic inflammation with a greater frequency in the sacrococcygeal region, and associated to the presence of hair. The treatment is eminently surgical. Aim: To demonstrate the endoscopic treatment of pilonidal cyst. Method: Prospective study with 67 patients who had as surgical indication the diagnosis of pilonidal cyst. They were submitted to a surgical procedure from June 2014 to March 2018. The equipment used was the Meinero fistuloscope, a shutter, a monopolar electrode, a brush and endoscopic forceps. Results: Of the 67 patients, 67% (n=45) were male and 33% (n=22) female, with a mean age of 25 years (17-45). Surgical time in average was 40 min (20-120) and mean healing time of four weeks (3-12). Surgical complications were presented in 7% cases (n=5) and recurrences in 9% (n=6). Conclusion: The endoscopic treatment of the pilonidal cyst is feasible and presents good surgical results.摘要 一、研究背景：藏毛囊肿（pilonidal cyst）是一种累及皮肤及皮下组织的感染性疾病，继发于慢性炎症，在骶尾部区域的发病率更高，且与毛发存在相关，临床治疗以手术为主。 二、研究目的：论证藏毛囊肿的内镜治疗方案。 三、研究方法：本研究为前瞻性研究，纳入67例经确诊为藏毛囊肿且符合手术指征的患者，所有受试者均于2014年6月至2018年3月期间接受手术治疗。所用手术器械包括迈耶罗瘘管镜（Meinero fistuloscope）、遮光器、单极电凝电极、毛刷及内镜钳。 四、研究结果：67例患者中，男性45例（占比67%，n=45），女性22例（占比33%，n=22），平均年龄25岁（年龄范围17~45岁）。平均手术时长为40分钟（手术时长范围20~120分钟），平均愈合时间为4周（愈合时间范围3~12周）。术后并发症发生率为7%（共5例），复发率为9%（共6例）。 五、研究结论：藏毛囊肿的内镜治疗方案具备临床可行性，且可取得良好的手术疗效。
