Sinus laser therapy versus Karydakis flap procedure in the management of pilonidal sinus disease: a comparative analysis of intraoperative parameters and postoperative outcome

This study aimed to investigate the utility of minimally invasive sinus laser therapy (SiLaT) versus flap surgery (Karydakis flap procedure) in terms of intraoperative parameters and postoperative outcome in patients with pilonidal sinus disease (PSD).

A total of 106 patients with PSD (mean ± SD age: 26.4 ± 7.0 years, 86.8% male) treated with Karydakis flap procedure (KF group; n = 63) or sinus laser therapy (SiLaT group; n = 43) were included in this retrospective study. Data on patient demographics, operative characteristics (number of openings, length of sinus tract, and operative time), and postoperative outcome including postoperative (day 1) pain intensity-visual analog scale (VAS) scores, time to return to work after surgery (days), complication rate, and recurrence rate were recorded in each patient and compared between KF and SiLaT groups.

The SiLaT versus KF procedure was associated with significantly shorter operative time [median (min–max) 17 (12–28) versus 27 (20–44) min, p = 0.001], lower pain scores [3 (1–4) versus 5 (3–7), p = 0.001], and earlier return to work [1 (1–3) versus 10 (5–20) days, p = 0.001]. Although no significant difference was noted in complication and recurrence rates between the KF and SiLaT groups, 6.3% (wound infection only) and 3.2% of patients in the KF group but none of the patients in the SiLaT group developed complication and recurrence, respectively.

SiLaT seems to be a promising minimally invasive technique for the management of PSD, being comparable to the KF procedure in terms of complications and recurrence, along with added advantages of shorter operative time, reduced postoperative pain, and earlier return to work.
