This study investigates abdominal muscle strength after surgery for giant hernia with the onlay, sublay or intraperitoneal (IPOM) method. Theoretically, placement of the mesh may result in different possibilities regarding function and postoperative physical activity related to abdominal muscle function.
Twenty-four patients operated for large ventral hernias using the onlay, sublay or IPOM technique were evaluated 1 year following surgery for abdominal wall strength using Biodex system 4.
Despite the different surgical techniques used, no differences were observed in abdominal wall strength between the groups.
The postoperative strength of abdominal wall muscles is independent of the method used for reconstruction of large abdominal wall hernia, and the choice of surgical technique should be directed by anatomical circumstances.
