Chapter 4.2.3 102 RESULTS Demographics: The demographics and operative variables for both cohorts are displayed in Table 1. Besides of subtotal hysterectomy in 40-50% of patients, no other concomitant interventions were performed. In the sutures only group, 40% (n=8) had a concomitant rectopexy; in the glue group, that was 45% (n=9) (ns). In patients who had a concomitant rectopexy, the total number of sutures in patients was higher (24 [18-28] versus 17 [11-22]). Costs: Relevant cost components are displayed in Table 2. Suture-associated costs logically depend on the number of sutures used, which were notably fewer in the glue group, as well as in patients where no rectopexy was performed. Despite more sutures required for rectopexy, the costs were not higher, which coincides with a lower cost for Vicryl sutures. The average cost of consumables for mesh fixation was significantly lower (-35% [2% - 81%]) in the sutures only, than in the glue group (p<0,0001). Conversely, the mean duration of mesh fixation was significantly shorter (-33% [27% - 75% ]) in the glue group than in the sutures only group (p<0.001). As a consequence, the average OR maintenance cost for mesh fixation was 33% [0% - 75%] lower in the glue than in the sutures only group (p<0.001). The relative contribution of the consumables used for mesh fixation in both groups is displayed in Figure 2, visualizing the contribution of both type of costs to the total cost. When considering both the consumables and operation room exploitation costs (€826.35 per hour), the average cost for mesh fixation was 14% [8% to 55%] lower in the glue as compared to the suture group. This corresponds with an average difference in fixation cost of €126.39 [€49.71– €715.3].
