Botulinum Toxin to Avoid Component Separation in Midline Large Hernias

Introduction. The goal of our study was to compare results in patients with large midline incisional hernia (LMIH) using only anterior compònent separation (CST) versus preoperative botulinum toxin (BT) and following Rives repair (RSR). Material and methods. From to December 2016 to December 2018, a prospective comparative study was performed in 80 consecutive patients with LMIH and hernia transverse diameter between 12-18 cms at our tertiary center. Two groups were prospectively analyzed: patients underwent open CST (component separation group or CSG) and patients with preoperative BT administration and following open RSR (botulinum toxin group or BTG).
