New Surgical Strategy for #Abdominal Wall Defects. A Successful Swine Model Experiment by Florina Popa in BJSTR
Abstract
Background: The purpose of this study was to develop a large
incisional hernia pattern made on an animal that is clinically relevant,
to
design a new original surgical technique to repair abdominal wall defect, and to evaluate its effectiveness, aiming to apply it on
patients.
Methods: Physical examination and ultrasound scan was performed at fixed intervals at 3, 7, 14 and 30 days. Postoperative complications
were followed. To evaluate the resistance of the repair, the swine model went through gestation and given birth process.
Results: There are the following situations: wound infection,
enteric fistula, stoma, or retraction of the abdominal wall, when direct
synthetic mesh repair is inadequate. Biological meshes may be placed to
achieve abdominal wall reconstruction, but they are associated with a
high recurrence risk. The good result is based on the flap properties of
biocompatibility and incorporation into the surrounding tissue. If some
surgeons questioned the flap repair, which would not provide the
required resistance, the reinforcement with the mesh would ensure it.
The
advantage of using the flap directly into the defect reduces the risk of
infection. Mechanical test of abdominal rectus muscle across the repair
site was performed and no test is better than the gestation and given
birth process.
Conclusion: The technique accomplishes the reconstruction of a
functional dynamic abdominal wall via the antilogous vascularized tissue flap and the mesh insertion, which will reinforce the repair. We
recommend it due to the fast tissue regeneration and resistance to
pressure
forces on different physiological acts.
