The outcomes of component separation technique versus no component separation technique in the repair of large ventral hernias and impact on quality of life: a multicenter retrospective cohort study.

Purpose: This study aimed to compare the results of patients who underwent anterior component separation techniques (ACST) and those who did not undergo component separation techniques (non-CST) in complicated ventral hernia repairs (VHRs) and to investigate the effect of these techniques on quality of life (QoL). Methods: A total of 105 patients who were operated for large ventral hernias were retrospectively analyzed. The patients were divided into the ACST group (n = 48) and the non-CST group (n = 57). Demographic, intraoperative, and postoperative data were recorded. Postoperative follow-up was conducted at 2 and 4 weeks, and 6, 12, and 24 months. The primary and secondary outcomes and QoL were measured. Results: The female ratio was higher in both groups (P = 0.512). There was no significant difference between age and body mass index between the groups (P = 0.705 and P = 0.803). The mean defect size and mesh size were similar between the groups (P = 0.775 and P = 0.245). The mean operation duration and amount of blood loss were similar between the groups (P = 0.801 and P = 0.142). There was no statistically significant difference in the median visual analog scale scores between the groups (P = 0.551). During follow-up, only 3 patients (6.3%) in the ACST group and 4 patients (7.0%) in the non-CST group had recurrence. There was no significant difference in the short- and long-term QoL between the groups. Conclusion: The ACST is a feasible surgical option for patients with complicated VHRs. In addition, by improving QoL, the recurrence rate is similar to patients undergoing standard VHR.
