Recurrence Patterns in Pilonidal Sinus Disease Surgery: Navigating Misclassifications and Early Complications

The one-year RR is containing a respectable portion of misclassifications (untrue recurrences) that may exceed the true recurrence rate by a factor of 3-5. If reliable recurrence rate needs to be determined, follow ups of <one year should be avoided. Studies of n=200 participants and larger exhibit a smaller chance of recurrence rate error and should be aimed for if possible. What does this paper add to the literature? This is the first work to quantify the amount of misclassification of "recurrences" within the first year following PSD surgery.
