Pilonidal sinus laser-assisted closure (PiLAC) - a low-morbidity alternative to excision with excellent long-term outcomes
Abstract
Introduction: Recurrence after surgery for pilonidal sinus disease is a recognised problem and patients often re-present months after discharge. We routinely treat primary and recurrent pilonidal sinus disease with Pilonidal sinus Laser-Assisted Closure (PiLAC). Long-term outcomes following PiLAC surgery was examined following clinical and telephone review.
Methods: All patients undergoing PiLAC as a day-case between April 2016 and July 2019 were included. Patients were followed up in a nurse-led clinic until complete healing or recurrence. A prospective database and retrospective audit of notes combined with longer-term follow-up by telephone were used.
Results: A total of 35 patients underwent PiLAC, median age 28 (18-53 years), 28 males:7 females. A total of 28 patients had long-term (>60 days) follow-up, mean 407 days (range 67-887 days); 25/28 patients (89.3%) had healed with no recurrence on long-term follow-up. Of these 28 patients, 11 were first presentation of pilonidal disease and underwent PiLAC as their first treatment, with a 91% heal rate long term. A total of 15 patients had seton drainage prior to PiLAC, with a 93% heal rate versus no seton (83%). Fisher's exact test showed no significant difference between sex, new/recurrent pilonidal disease and seton placement (p>0.05).
Conclusions: Healing after PiLAC for the treatment of primary and recurrent pilonidal sinus disease is preserved with excellent long-term outcomes. We recommend it as an alternative to surgical excision.
