Chapter 8 198 Secondary outcomes Fissure recurrence In the total group of patients, after one year, the fissure recurred in 15 patients (15.5%), 60% women and 40% men. In the PFPT-group, in 11.3% vs 20.5% in the postponed PFPT-group. No significant difference was found between groups at 1-year follow-up. Pain VAS- pain was significantly reduced in the total group of patients from baseline to follow-up at 1 year (mean estimated difference 4.23; 95% CI, 3.82 to 4.66; p<0.001). In the PFPT group and the postponed PFPT group the pain score measured with VAS, decreased significantly from baseline to 1-year follow-up (p<0.001) (Table 2). No significant differences were found between groups at 1-year follow-up (Table 2). Regarding the analysis of repeated measures, the PFPT group was found to be more effective for reducing pain compared to the postponed PFPT group at 1 year from baseline (p<0.001) (Figure 2.2; Table 2). Figure 2.2 Repeated measures pain (VAS)-score Pelvic floor function Increased pelvic floor muscle tone measured with digital rectal examination was found in 87.1% of the total group of patients at baseline and in 19 patients (19.6%) at 1-year follow-up (p<0.001). 14 patients in the PFPT group vs 5 patients in the postponed
