Abstract: Objective To compare the efficacy of primary resection and suture versus rhomboid flap transfer in the treatment of sacrococcygeal pilonidal sinus. Methods We retrospectively analyzed 61 patients with sacrococcygeal pilonidal sinus. They were divided into a resection group （n=25） and a flap group （n=36）. Operative time, length of hospital stay, complication rate, recurrence rate, and postoperative aesthetic satisfaction were compared between the two groups. Logistic regression was used to analyze risk factors for postoperative complications and recurrence. Results The two groups were comparable in terms of baseline characteristics, including sex, age, and disease duration. Operative time was significantly shorter in the resection group than in the flap group （P< 0.05）. In contrast, the length of hospital stay was significantly shorter in the flap group （P< 0.05）. Recurrence and complication rates were significantly lower in the flap group （P< 0.05）, whereas postoperative aesthetic satisfaction was higher in the resection group （P< 0.05）. Length of hospital stay was a risk factor for postoperative complications（OR=1.551,P=0.019）. Conclusion Compared with primary resection and suture, rhomboid flap transfer is associated with lower rates of postoperative complications and recurrence, and a shorter hospital stay, making it an effective treatment for sacrococcygeal pilonidal sinus.However, it is associated with a higher risk of scar formation and a longer operative time.

摘要： 目的 对比一期切除缝合术与菱形皮瓣转移术治疗骶尾部藏毛窦的疗效。方法 回顾性分析我院收治的61例骶尾部藏毛窦患者,分为切除组（25例）和皮瓣组（36例）。对比分析两组患者的手术时间、住院时间、并发症发生率、复发率及术后美观满意度,采用logistic回归分析影响术后并发症及复发的危险因素。结果 两组患者的性别、年龄、病程等基线资料具有可比性。切除组的手术时间显著短于皮瓣组（P<0.05）;皮瓣组的住院时间显著短于切除组（P<0.05）,复发率和并发症发生率亦均显著低于切除组（P<0.05）。切除组术后美观满意度高于皮瓣组（P<0.05）。住院时间是影响术后并发症发生的危险因素（OR=1.551,P=0.019）。结论 与一期切除缝合术相比,菱形皮瓣切除术后并发症发生率及复发率更低,患者住院时间更短,是治疗骶尾部藏毛窦的有效方法。但其术后易形成瘢痕,且手术时间更长。
