Plain-English summary
This study looked at a new surgical method called posterior flap hernioplasty for treating complex ventral hernias, which are large openings in the abdominal wall. Seven patients with hernias larger than 10 centimeters had this surgery, which took about 107 minutes and resulted in minimal blood loss. They spent an average of just one day in the hospital and reported mild pain afterward. While there were a couple of minor issues, like one patient developing a hematoma (a collection of blood outside of blood vessels) and another experiencing a recurrence of the hernia, the overall results were positive. This technique seems to be a safe and effective option for repairing large hernias, but more research is needed to confirm its long-term benefits and cost savings.
Abstract
Complex ventral hernias remain challenging due to large fascial defects and loss of domain. The posterior flap hernioplasty is a simplified modification of posterior component separation that enables wide preperitoneal mesh placement without extensive dissection or adjunctive techniques. In this retrospective series, 7 patients with midline hernias greater than 10 cm underwent repair using this approach. The mean operative time was 107 minutes, the mean blood loss was 137 mL, and the median hospital stay was 1 day. Postoperative pain averaged 3 ± 1.1, with no systemic complications. One hematoma (14%) and 1 recurrence (14%) occurred at a median follow-up of 6 months. This technique provides a safe, reproducible, and resource-efficient alternative for large midline hernias, achieving tension-free closure and rapid recovery. Further comparative studies are required to validate long-term outcomes and cost-effectiveness.
