[Differentiated approach to surgical treatment of patients with large postoperative ventral hernia]

To analyze the results of large postoperative ventral hernia repair using the Rives-Stoppa technique and posterior component separation between 2018 and 2023.

We retrospectively analyzed 55 case histories of patients with large postoperative ventral hernias. The Rives-Stoppa technique was used in 25 (45.5%) patients, posterior component separation - in 30 (54.5%) patients.

The classical Rives-Stoppa technique was predominantly performed in women (mean age 67.3±1.2 years). In 20 (80%) patients, hernia defect did not exceed 14 cm. Mean wound drainage time was 3.8±0.7 days, mean postoperative in-hospital stay - 12.7±2.4 days. Posterior component separation was more common in men, whose age was significantly lower (58.4±2.0 years, U=160.500, p<0.001). This technique was significantly more common for hernia > 15 cm (14 (47%) patients, c²=4.288, p=0.038). Mean wound drainage time was 9.7±0.8 days, mean postoperative in-hospital stay - 18.8±1.6 days (p<0.001). In early postoperative period, 15 (27.3%) patients had wound complications. There was no significant difference in the incidence of wound complications (p=0.808), and no deaths were recorded.

A differentiated approach is necessary for large hernias. Some elderly and senile patients underwent Rives-Stoppa procedure. Posterior component separation is required for anterior abdominal wall reconstruction in young and middle-aged men. Posterior component separation significantly increases the wound drainage time and hospital-stay, but does not significantly affect the incidence of wound complications.
