Is it beneficial to add laser ablation to curettage in the treatment of pilonidal sinus disease?

Abstract

Aim: This study aimed to compare laser application with sinus curettage against only sinus curettage in the treatment of pilonidal sinus disease (PSD) in terms of postoperative complications, wound healing, and recurrence. Additionally, we aimed to investigate factors associated with wound healing and recurrence after PSD surgery.

Patients and methods: This study included patients diagnosed with PSD between February 2019, and September 2022. The patients were randomly assigned to either the laser + curettage (L/C; n = 40) group or the curettage-only (C; n = 40) group. The following data were collected: demographic and anthropometric information, smoking status, comorbidities, number of PSD-related orifices, complicated or uncomplicated disease, prior recurrence, postoperative findings, wound healing problems within 30 days postoperatively, and recurrence within 6 months postoperatively.

Results: The L/C and C groups were similar in terms of age and sex distribution. The groups had similar results for postoperative pain, discharge, bleeding, wound healing problems at 30 days, and recurrence at 6 months. Multivariable logistic regression revealed that, high weight and higher orifice count were independently associated with wound healing problems. Additionally, high weight, higher orifice count and prior recurrence were independently associated with recurrence.

Conclusion: Combined curettage and laser therapy showed non-significant but broad benefits over curettage alone, but statistical significance was not achieved in any of the adverse findings, as well as wound healing and recurrence. Higher body weight and higher orifice count were associated with both poor wound healing and recurrence, while prior recurrence was another factor associated with recurrence at 6 months.
