Comparative Outcomes of Surgical Techniques for Pilonidal Sinus: A Turkish Retrospective Study

Le résumé fourni par la source

BACKGROUND Pilonidal sinus is a chronic or acute infectious disease in the intergluteal cleft. Various surgical treatments exist, but optimal management remains debated. This study compares outcomes of primary midline closure (PMC), Karydakis flap (KF), Limberg flap (LF), and laser pilonidotomy (LP) in adult patients with pilonidal sinus disease. MATERIAL AND METHODS The data of 476 patients who underwent surgery for pilonidal sinus disease in our clinic between January 2011 and September 2022 were retrospectively evaluated. After 54 patients were excluded, the remaining patients were divided into 4 groups: PMC (n=228), LF (n=82), KF (n=53), and LP (n=59). Patient characteristics, surgical findings, and quality of life outcomes were compared between the groups. RESULTS The operation time was significantly shorter in the LP group (P<0.001). Seroma (P=0.006), wound dehiscence (P<0.001), and postoperative recurrence (P=0.017) rates were significantly higher in the PMC group. Hospital stay was significantly shorter in the LP group (mean, 8 h; P<0.001). Pain-free toilet sitting time, pain-free walking time, and return to work time were statistically significantly shorter in the LP group (all P<0.001). According to the Likert scale, the satisfaction rate of the LP group was significantly higher (P<0.001). CONCLUSIONS The PMC method has a higher postoperative complication rate and a slower return to normal physical activity. The KF method appears to be more advantageous in terms of postoperative recurrence rate. Although the LP method seems to be more advantageous in terms of quality of life in selected patients, studies with larger samples and longer follow-up periods are needed.
