22. MINIMALLY INVASIVE TREATMENT OF PILONIDAL SINUS: A SINGLE-CENTER COHORT STUDY ON SHORT-TERM OUTCOMES

Abstract

Abstract Introduction Pilonidal sinus is a benign condition that causes infections and abscesses in the intergluteal area, but its physiological explanation is still unclear. There are various surgical techniques to treat it, such as excision with marsupialization, primary closure, and endoscopic pilonidal sinus treatment (EPSiT). Methods Forty-six patients between 13 and 23 years of age, who underwent surgery for pilonidal sinus between 01/01/2020 and 31/12/2022, were analyzed. Three techniques were performed: marsupialization, primary closure, and EPSiT by different surgeons in the same hospital complex. A p-value of <0.05 was considered significant. Results Significant differences were observed in terms of gender, with a predominance of males, and in the number of interventions performed. Regarding postoperative results, significant differences were found in bleeding and hematoma formation. Bleeding was greater in the EPSiT group, although hematoma was significantly lower. Furthermore, differences were found in the patient's follow-up time and attendance at healthcare centers for dressing changes. No significant differences were found in other analyzed variables. Conclusion The peak incidence of pilonidal sinus is typically estimated during the second decade of life, with a predominant occurrence in males. The maximum recurrence occurs within the first three years after the intervention. This study suggests that EPSiT offers significant advantages by reducing the risk of hematoma and, therefore, wound infection compared to classical techniques. However, we rely on retrospective data from a new technique, with a learning curve and limited follow-up. Additionally, the sample size is limited. Further research with longer follow-up is needed.
