Abstract Background This study aimed to evaluate the results of posterior component separation (CS) and transversus abdominis muscle release (TAR) with retro-muscular mesh reinforcement in patients with primary abdominal wall dehiscence (AWD). The secondary aims were to detect the incidence of postoperative surgical site occurrence and risk factors of incisional hernia (IH) development following AWD repair with posterior CS with TAR reinforced by retromuscular mesh. Methods Between June 2014 and April 2018, 202 patients with grade IA primary AWD (Björck's first classification) following midline laparotomies were treated using posterior CS with TAR release reinforced by a retro-muscular mesh in a prospective multicenter cohort study. Results The mean age was 42 ± 10 years, with female predominance (59.9%). The mean time from index surgery (midline laparotomy) to primary AWD was 7 ± 3 days. The mean vertical length of primary AWD was 16 ± 2 cm. The median time from primary AWD occurrence to posterior CS + TAR surgery was 3 ± 1 days. The mean operative time of posterior CS + TAR was 95 ± 12 min. No recurrent AWD occurred. Surgical site infections (SSI), seroma, hematoma, IH, and infected mesh occurred in 7.9%, 12.4%, 2%, 8.9%, and 3%, respectively. Mortality was reported in 2.5%.

Objectives: Preoperative botulinum toxin type A (BT) and progressive pneumoperitoneum (PPP) are useful tools in the preparation of patients with loss of domain hernias (LODH). The purpose of our retrospective study is to report our experience in the treatment of 100 consecutive patients with LODH, with the combined use of these techniques.Methods: Of the 753 patients operated on for ventral incisional hernia between June 2010 and December 2018 in our hospital, 100 patients with LODH were analyzed retrospectively. Diameters of abdominal cavity and hernia sac, and volumes of incisional hernia (VIH) and abdominal cavity (VAC) were calculated from CT scan, based on the index of Tanaka.Results: The median insufflated volume of air for PPP was 8,600 ± 4,200 cc (4,500–15,250). BT administration time was 38.2 days (33–48). A significant average reduction of 15% of the VIH/VAC ratio was observed on CT scan after the combination of PPP and BT (p = 0.001). Anterior component separation (CST) and transversus abdominis release (TAR) were the most frequent repair techniques. Complete fascial closure was possible in 97%, and mesh bridging was needed in three cases. In postoperative follow-up of 34.5 months (11–62), we reported eight cases of hernia recurrence (8%).Conclusion: PPP and BT are useful tools in the treatment of LODH. These techniques significantly reduce the VIH/VAC ratio, allowing the reduction of the hernia content into the abdominal cavity, which represents a key factor in the management of these hernias.
