Abstract
BACKGROUND: Complex ventral hernias (VHs) represent a real challenge to both general and plastic surgeons. This study aims to compare Sublay Mesh-Only Repair to Posterior Component Separation "PCS" with Transversus Abdominis Release "TAR" in the treatment of complex ventral-wall hernias (VHs). METHODS: This a randomized, controlled, intervention, including two parallel groups: A; Sublay Mesh-Only Repair and Group B; "TAR". Consecutive patients of both genders aged between 18 and 65 years old with complex VHs presented at Mansoura University Hospitals including large-sized abdominal-wall hernia ≥ 10 cm in width, loss of domain ≥ 20%, multiple hernial defects, or recurrent hernias. Immuno-compromised patients, patients with liver impairment, or severe heart failure were considered an exclusion criterion. The primary outcome is the recurrence rate after 12-months following the procedure. RESULTS: Fifty-six patients were recruited in this study. There was no significant difference between both groups regarding recurrence. However, there was significant differences between both groups regarding seroma favoring mesh-only repair. CONCLUSIONS: Although TAR may be associated with longer operative times and more blood losses, these were not found to be statistically significant. Postoperative complication, except for seroma, and recurrence rates were comparable in both groups. Trail registration The study was registered on clicaltrials.gov "NCT04516031".
