Open versus laparoscopic incisional hernia repair: something different from a meta-analysis

Background Incisional hernias after laparotomy are a large financial burden for society as well as for the patients suffering from pain and limitations of activity over time. The introduction of alloplastic materials such as polypropylene seems to improve the results. The question of whether to apply open or laparoscopic implantation of the mesh is of ongoing interest. We compare the available alloplastic materials and try to clarify the question of whether the laparoscopic procedure is superior to the conventional (open) technique based on the available randomized studies.
