Improving Surgical Techniques for Repairing Medium and Large Postoperative Median and Median-Lateral Ventral Hernias

What this Trial Is About

Researchers are studying surgical treatments for patients with postoperative ventral hernias located in the middle and side areas of the abdomen. The focus is on medium and large hernias classified as W2 and W3 and aims to improve treatment outcomes by developing new surgical techniques. The study will explore the anatomy of blood vessels and nerves in different layers of the abdominal wall to reduce complications and improve recovery. The study compares two groups a control group who received standard treatment methods for incisional ventral hernias and an experimental group treated with newly developed surgical techniques. These new methods focus on preserving important blood vessels and nerves while creating the implant bed, including a novel approach for repairing mid-lateral hernias by combining retromuscular and subaponeurotic spaces. The clinical phase includes up to 80 patients, with treatments performed over 1.5 to 2 years. Participants will undergo assessments before and after surgery, including CT scans and ultrasound to evaluate blood supply and fluid accumulation in the implant area. Researchers will monitor immediate results for up to one year, tracking treatment time, pain, seromas, hematomas, infections, and complications. Long-term follow-up of 1 to 1.5 years will assess hernia recurrence and late complications such as fistulas or persistent pain. Data will be analyzed using advanced statistical methods to evaluate the effectiveness and safety of the new surgical techniques.
