Standard Closure vs. Integrated Mesh-Fascial Closure (IMFC) for Incisional Hernia Repair

This study compares two surgical techniques for closing the abdominal wall in adult patients who have an incisional hernia (a weakness or opening in a previous surgical incision) or who require prophylactic mesh placement during a laparotomy. In one group, the abdominal wall is closed using the standard technique, in which a polypropylene mesh is fixed independently from the fascial suture. In the other group, a new technique called Integrated Mesh-Fascial Closure (IMFC), developed by the research team, is used: the mesh is incorporated directly within the same continuous suture line that closes the abdominal wall, aiming to better distribute tension across the surgical wound. The choice of technique is made by the patient after receiving information about both options and providing informed consent. Participants will be followed clinically and with imaging for 18 to 24 months to evaluate the safety, technical feasibility, and reproducibility of the IMFC technique, and to determine the incidence of hernia recurrence in both groups.
