Primary ventral and incisional hernias are frequent conditions that impact the quality of life of patients. Surgical techniques for ventral hernia repair are constantly evolving and abdominal wall surgery has turned into a highly specialized field. This is a narrative review of the most recent and relevant literature on the treatment of primary ventral and incisional hernias performed by eight experts in ventral hernia surgery from across the world and includes review of classification systems, preoperative measures, descriptions of surgical techniques, and postoperative complications. Repairs of primary ventral and incisional hernias range from simple open procedures in healthy patients with small defects to complex procedures when patients are co-morbid and have large defects. Optimizing patient-related risk factors before surgery is important to decrease complication rates. Surgical repair techniques from open repairs to minimally invasive procedures are described in detail in the review. Minimally invasive techniques are technically more demanding and take longer, but decrease the risk of surgical-site infections and shorten the duration of hospital stay. Treatment of ventral hernias aims to improve the quality of life of patients. The risks and benefits of procedures should be weighed against patients' complaints and co-morbidities. Optimizing patient-related risk factors before surgery is important.
