Postoperative results of modified Karydakis flap method for primary sacrococcygeal pilonidal sinus disease: short and long-term analysis.

BACKGROUND: Sacrococcygeal pilonidal sinus is a common surgical condition that requires various treatment options. This study aims to investigate the short and long-term outcomes of the modified Karydakis flap method in patients with sacrococcygeal pilonidal sinus.

METHODS: A retrospective analysis was conducted on 175 patients who underwent the modified Karydakis flap method for sacrococcygeal pilonidal sinus by a single surgeon between September 2015 and February 2021. The patients' demographics, operative time, hospitalization time and complications were recorded.

RESULTS: Of the 175 patients, 125 (71.43%) were male and 50 (28.57%) were female, with a mean age of 24.93 ± 10.27 years. The mean operative time was 55.05 ± 12.33 min, the follow-up time was 39.21 ± 17.58 months, and the mean hospitalization time was 3.4 ± 1.65 days. Complications were observed in 12 (6.85%) patients, including seroma (5.14%) and wound infection (1.71%), with no observed cases of flap necrosis or recurrence.

CONCLUSION: The modified Karydakis flap method appears to be a safe and effective treatment option for sacrococcygeal pilonidal sinus, with an acceptable complication rate and no observed cases of recurrence.
