Abstract

INTRODUCTION:: Minimally-invasive endoscopic techniques for pilonidal sinus disease (PSD)—endoscopic pilonidal sinus treatment (EPSiT) and endoscopic sinus laser-assisted closure (E-SiLaC)—have shown favorable short-term outcomes, but long-term data from Asian populations are scarce.

AIM:: We aimed to report 5-year outcomes of EPSiT and E-SiLaC in a prospective Vietnamese cohort.

MATERIALS AND METHODS:: A total of 18 consecutive patients treated with EPSiT (n = 15) or E-SiLaC (n = 3) between January 2019 and December 2023 were prospectively enrolled. Treatment method was selected by shared decision-making, and all procedures were performed by a single surgeon. The patients were reviewed fortnightly until healing, then annually. The outcomes included operative time, pain (as measured by the Visual Analog Scale [VAS]), healing time, time to return to regular activities, as well as recurrence and satisfaction rates.

RESULTS:: Of the entire study population, 11 patients (61.1%) were men. Mean (SD) age of the study cohort was 30.3 (13.2) years and mean body mass index was 23 (3.6) kg/m2. Ten participants (55.6%) had prior PSD surgery. Mean operative time was 32.5 (7.9) minutes and mean VAS score was 2.8 (1.8). Median healing time was 25 days (range, 7–45 d) and mean times to return to regular activities and to work were 7.2 (4.3) and 14.4 (9.7) days, respectively. After median follow-up of 60 months (range, 1.1–86.9 mo), 15 patients (83.3%) achieved complete healing. Recurrence was reported in 2 participants (11.1%), both in the EPSiT group and both successfully salvaged. No recurrence was recorded in the E-SiLaC group; 1 E-SiLaC case represented successful salvage of prior EPSiT failure, with sustained healing at 59 months of follow-up. All patients reported satisfaction with the achieved outcomes, and 88.9% would recommend the procedures.

CONCLUSIONS:: EPSiT and E-SiLaC are safe, effective, and durable options for PSD, including in patients with prior surgical failure. Larger comparative studies are warranted to confirm this finding.
