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

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.
