Selected patients were scheduled for follow-up, and all patients were instructed to contact the department in case of continuous or recurrent complaints for a clinical assessment of persistent disease or recurrence at the outpatient clinic. Persistent or residual disease within 2\u2009months after the procedure was classified as residual disease, whereas disease detected after 2\u2009months was classified as recurrence. Final rates of persistent disease and recurrence were assessed retrospectively from electronic medical records in December 2024.

Disease recurrence occurred in nine patients (11%). The mean duration of sick leave was 3.0 (SD = 4.7) days.
