Can a flap made from the hernia sac itself prevent mesh complications?
NCT ID NCT07720154
First seen Jul 22, 2026 · Last updated Aug 19, 2026 · Updated 3 times
Summary
This trial tests whether preserving the hernia sac as a living flap and stitching it under the mesh can reduce wound and mesh problems after complex ventral hernia repair where the defect has a bony edge. Half of the 180 participants will receive the standard repair plus the sac flap; the other half will receive standard repair alone. The main question is whether the flap lowers the rate of surgical site occurrences within 30 days, such as infection, seroma, or mesh exposure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a surgical procedure that uses the patient's own hernia sac as a living flap to cover the mesh
- What this could lead to
- If successful, this technique could lower the risk of wound infections, seromas, and mesh-related complications after complex hernia surgery, without added cost or donor tissue.
- What could go wrong
- This is a single-center trial with 180 participants, so results may not apply broadly. The flap may not always be usable, and the procedure adds complexity to the operation.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18 years or older. * Elective open repair planned for a complex ventral hernia (primary or incisional) in which at least one margin of the fascial defect is formed by bone - that is, a subxiphoid or costal-margin, suprapubic, or iliac or lumbar location - confirmed on cross-sectional imaging (CT or MRI) and at operation. * A hernial sac of sufficient quality and surface area to raise a pedicled flap adequate to cover the planned mesh, as judged at operation. * Planned retromuscular (sublay) synthetic mesh repair, with or without posterior component separation (transversus abdominis release). * Able to give written informed consent and to attend scheduled follow-up for 12 months. Exclusion Criteria: * Emergency or urgent operation (incarceration with strangulation, obstruction, or perforation). * Active intra-abdominal infection, or a contaminated or dirty operative field (CDC wound class III-IV) at the time of randomization. * Planned use of biologic or composite intraperitoneal mesh, or a bridged (non-fascial-closure) repair as the primary plan. * Hernial sac absent, destroyed, densely scarred, or too small to raise a viable covering flap. * Concurrent bowel resection or stoma creation expected to alter the wound-contamination class. * ASA physical status V. * Life expectancy less than 12 months, or active malignancy under treatment with anticipated short survival. * Pregnancy. * Inability or unwillingness to provide informed consent or to comply with follow-up
