Incisional hernias, which occur at the site of a previous surgical incision in the abdomen, are often managed by reinforcing the weakened area, usually where the fascia (connective tissue) has not adequately healed. Skilled surgeons like Dr. Iskandar use techniques like laparoscopy, employing a laparoscope for a detailed view of the internal structures, to repair these hernias with minimal disruption to the surrounding skeletal muscles and tissues.
