Endoscopic pilonidal sinus treatment versus total excision with primary closure for sacrococcygeal pilonidal sinus disease in the pediatric population

Abstract Purpose To evaluate the effectiveness and safety of Endoscopic Pilonidal Sinus Treatment (EPSiT) in the pediatric population and compare it with excision followed by primary closure (EPC) regarding intra- and postoperative outcomes. Methods A retrospective analysis of all patients with chronic sacrococcygeal pilonidal sinus submitted to EPSiT and EPC during a 12-month period in our institution was performed. Data concerning patients' demographics and surgical outcomes were collected and compared between the two groups. Results We analyzed a total of 21 cases that underwent EPSiT and 63 cases of EPC, both groups with similar demographic characteristics. Operative time was similar for both groups (30 vs. 38min; p>0.05). No major intraoperative complications were reported. Wound infection rate was lower for EPSiT ((5.2% [n=1] vs. 20.0% [n=12]); p>0.05). Healing time was similar for both groups (28 vs. 37.5days). Recurrence occurred in 18,9% (n=15), with 2 cases (10.5%) reported in the EPSiT group versus 13 (21.6%) in EPC. There were no differences between groups regarding postoperative complications, complete wound healing and recurrence rates or healing time (p>0.05). Conclusions Our results suggest that EPSiT is as viable as excision followed by primary closure in the management of sacrococcygeal pilonidal sinus in the pediatric population. Level of evidence Therapeutic study – level III.
