  • Authors were contacted when data were missing for follow-up. Of note, in several studies (indicated with an *), the follow-up rate or complications rate were calculated over different subgroups; therefore, columns may not add up or correlate. aWhen available, this review reports the number of patients who received surgery; when not available, the number of procedures was used; when not available, the number of diagnosis was used. bWhen studies reported a range of follow-up intervals, the shortest length of follow-up was used for calculations. cWhen the total number of patients who completed follow-up was not available, the total number of patients included was used (in line with the cited articles). dThe complication rate cited was calculated over the total number of procedures.
