Abdominal wall hernias and incisional hernias are a common benign disorder affecting quality of life, potentially leading to life-threatening complications. Laparoscopic IPOM (intraperitoneal onlay mesh) approach can offer good results in selected cases. Patients who underwent laparoscopic incisional/ventral abdominal hernia repair operated with standardized technique and the same mesh, from January 2011 to December 2022, were retrospectively considered. Four hundred consecutive patients underwent laparoscopic abdominal wall repair. There were 255 ventral hernia (63%) and 145 (37%) primitive hernia (epigastric and umbilical). Mean size of the defect was 4.2 cm, W3 were 19 (4%). After a mean follow-up of 1906 days (range 45-4109), no mesh-related complications have been detected. There were 10 (2.5%) recurrences and 20 (5%) bulging. In this study we emphasized the role of patient selection and standardized technique which represents "the lesson" learned over a period of 15 years of activity. In this setting, we believe that laparoscopic approach can achieve very good results in abdominal wall repair.
