BACKGROUND: The best treatment for the combined defects of midline and lateral incisional hernia is not known. The aim of our multicenter study was to evaluate the operative and patient-reported outcomes using a modified posterior component separation in patients who present with the combination of midline and lateral incisional hernia. METHODS: We identified patients from a prospective, multicenter database who underwent operative repairs of a midline and lateral incisional hernia at 4 centers with minimum 2-year follow-up. Hernias were divided into a main hernia based on the larger size and associated abdominal wall hernias. Outcomes reported were short- and long-term complications, including recurrence, pain, and bulging. Quality of life was assessed with the European Registry for Abdominal Wall Hernias Quality of Life score. RESULTS: Fifty-eight patients were identified. Almost 70% of patients presented with a midline defect as the main incisional hernia. The operative technique was a transversus abdominis release in 26 patients (45%), a modification of transversus abdominis release 27 (47%), a reverse transversus abdominis release in 3 (5%), and a primary, lateral retromuscular preperitoneal approach in 2 (3%). Surgical site occurrences occurred in 22 patients (38%), with only 8 patients (14%) requiring procedural intervention. During a mean follow-up of 30.1 ± 14.4 months, 2 (3%) cases of recurrence were diagnosed and required reoperation. There were also 4 (7%) patients with asymptomatic but visible bulging. The European Registry for Abdominal Wall Hernias Quality of Life score showed a statistically significant decrease in the 3 domains (pain, restriction, and cosmetic) in the postoperative score compared with the preoperative score. CONCLUSION: The different techniques of posterior component separation in the treatment of combined midline and lateral incisional hernia show acceptable results, despite the associated high complexity. Patient-reported outcomes after measurement of the European Registry for Abdominal Wall Hernias Quality of Life score demonstrated a clinically important improvement in quality of life and pain.
