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.
