P029 HOW DOES THE MADRID APPROACH WORK

Abstract

Abstract Aim The Madrid APPROACH is the combination of an absorbable mesh and a permanent retromuscular mesh for the treatment of the complex abdominal wall problems. It has been controversial because of the need of two different meshes. We present a clinic case to show the utility of this technique and how it allows rebuilding the inguinal ligament. Material and Methods 78 years old woman who underwent a right ilioinguinal and obturatriz lymphadenectomy due to a melanoma. Incisional hernia fixed in 2018 with a retromuscular polyester mesh. New incisional iliac hernia (L3) over the right iliac vessels, with an absence of inguinal ligament, right rectus atrophy, and the previous mesh being part of the sac. Surgery: incision over the previous scar. Wide dissection of the preperitoneal space, Retzius space and lateral to the cuadratus lumborum, retrodiafragmatic dissection, lateral transverse abdominus release, and cross-over to the retrorectal left space. Preperitoneal BioA mesh and an upper 40x40cm medium weight polipropilene mesh set to both Cooper ligaments. Results After two and a half months, a PET-TC showed the BioA mesh perfectly adapted to the abdominal wall and rebuilt a new inguinal ligament. Also intense FDG capitation of the mesh due to the high cellular metabolism. Two years later the patient has a continent abdominal wall, the follow up TC shows the disappearance of the absorbable mesh and the perfect abdominal wall rebuilt. Conclusions The BioA mesh acts like a tissue scaffold for new conjunctive tissue as we see the intense FDG captation. The Madrid APPROACH allows giving response to very complex abdominal wall problems.
