Abstract

Background

An emerging and promising minimally invasive treatment for pilonidal disease (PD) is sinus laser-assisted closure (SiLaC®). Previous studies have shown encouraging results concerning safety, patient satisfaction, wound healing and acceptable recurrence rates. This study investigated outcomes for a large cohort of PD patients treated with SiLaC®.

Methods

A multicentre cohort study with a prospective design and partial retrospective data collection for patients with PD treated with SiLaC® in three hospitals in the Netherlands (Albert Schweitzer Hospital, Flevoziekenhuis and Medical Centre Zuiderzee) from January 1st 2017 to March 1st 2020. The primary outcome was recurrence. Secondary outcomes were incidence of complete wound closure, time until wound closure, postoperative complications, ability to perform daily activities and reported patient satisfaction.

Results

A total of 311 patients were included with a median follow-up of 10 months (range 1–52 months). The recurrence rate after one SiLaC® treatment was 26% with 7% experiencing incomplete wound closure, resulting in an initial success rate of 66% after one SiLaC® procedure. This increased to 92% and 98% after two and three SiLaC® procedures, respectively. Mean time until wound closure was 6 weeks (range 1–24 weeks). Seven patients (2%) were still unsuccessfully treated after three SiLaC® treatments and required additional and extensive surgery. Mean time to perform regular daily activities including working was 6 days (range 0–42 days) and the vast majority of patients (84%) did not require painkillers or only paracetamol. Twelve patients (4%) developed a postoperative wound infection. The mean satisfaction score was 9 (range 5–10).

Conclusions

SiLaC® is a promising minimally invasive treatment for PD with high patient satisfaction and an acceptable success rate. These results suggest that SiLaC® could be used as a safe and effective primary treatment for PD.
