Title: The Effect of Mesh Fixation Technique on Postoperative Pain in Laparoscopic Correction of Incisional and Ventral Abdominal Wall Hernias.
Brief Summary: Method of fixation of the mesh in laparoscopic incisional / ventral hernia repair might influence the degree of postoperative pain.

The study hypothesis is that there is no difference in postoperative pain between different methods to fix the mesh in laparoscopic incisional / ventral hernia repair.
