Sinus laser closure (SiLaC) versus Limberg flap in management of pilonidal disease: A short-term non-randomized comparative prospective study

Abstract

IntroductionFistula Laser Closure (FiLAC) is a method that was originally applied in the treatment of perianal fistulas. Because of promising results, diode lasers were later on used to treat pilonidal sinus disease in a method called sinus Laser Closure (SiLaC).The aim of this study is to compare between SiLaC and Limberg flap in management of pilonidal disease. MethodsA prospective, nonrandomized comparative study. A short-term follow-up of 71 patients with pilonidal disease was analyzed (24 operated on using the SiLaC technique and 47 using the Limberg technique). With a primary outcome is healing rate and recurrence and a secondary outcome is other measures i.e. complications, hospital stay and postoperative pain. ResultsThe median operative time in the SiLaC group was 26.45 ± 5.41 min (20–35 min) and in the Limberg group 58.63 ± 7.42 min (50–75 min). In the SiLaC group, the primary healing was achieved in 23 out of 24 patients (95.8%) with a total complication rate of 20.83%. There were two cases of recurrence after initial healing in each group. ConclusionSinus laser Closure (SiLaC) is comparable to Limberg flap technique in the terms of healing rate and recurrence with better outcome regarding operative time, hospital stay and post-operative pain.
