Chapter 4.2.2 88 test, Chi-square test and survival analysis, when appropriate. We constructed survival curves for GRC, reinterventions for GRC and reinterventions for late postoperative complications. A p-value < 0.05 was considered statistically significant. When data from respondents were missing, this is reported as missing values; no data imputation was done. The audit was approved by the Ethics Committee on Clinical Studies (B322202042753) and prospectively registered on Clinicaltrials.gov (NCT04378400). Written informed consent was obtained from all participants. This paper follows the STROBE guidelines for reporting observational studies.158 RESULTS We identified 39 patients who underwent redo LSCP. They were matched with 156 controls, resulting in a study population of 195 patients. Except for the difference in the rate of prior POP surgeries and hysterectomies, baseline patient characteristics did not differ significantly between groups, as shown in Table 1. Table 1. Patient characteristics Patient characteristics Redo LSCP group (n = 39) Primary LSCP group (n = 156) P Age at surgery (years) 63.5 ± 10.7 64.9 ± 10.5 0.83 BMI (kg/m2) 26.2 ± 3.3 25.8 ± 3.7 0.61 Diabetes mellitus (all types) 4/39 (10.3%) 15/155 (9.7%) 1.00 Current smoker 5/39 (12.8%) 10/156 (6.4%) 0.19 Parity 2 (0-6) 2 (0-8) 0.33 Menopausal 34/39 (87.2%) 145/155 (93.5%) 0.19 Hormone therapy 4/35 (11.4%) 21/145 (14.5%) 0.79 Prior hysterectomy 33/39 (84.6%) 103/156 (66.0%) 0.02* Prior POP surgery 39/39 (100%) 90/156 (57.7%) <0.001* Prior incontinence surgery 10/39 (25.6%) 23/156 (14.7%) 0.11 Data are reported as mean ± SD, median (range) and number (%). Comparison between groups was performed by the two sample Student t-test, the Fisher’s exact or Chi-square test as appropriate. LSCP = laparoscopic sacrocolpopexy, BMI = body mass index, POP = pelvic organ prolapse.
