Abstract on TIGR® Matrix Surgical Mesh submitted at the 3rd World Congress for Plastic Surgeons of Chinese Descent.

Press Release   •   Oct 17, 2012 07:42 GMT

The submission of early results (1 year) TRAM flap data gathered by the Division of Plastic Reconstructive & Aesthetic Surgery at NUH Singapore is titled: Early results with rectus sheath repair using a TIGR® Matrix Surgical Mesh (TIGR® Matrix) following pedicled TRAM flap surgery for breast reconstruction; and documents early results with the use of a synthetic resorbable mesh – TIGR® Matrix as an on-lay graft over a rectus sheath repair in patients who had undergone pedicled TRAM flap for breast reconstruction.

The pedicled transverse rectus abdominis myocutaneous (TRAM) flap is a workhorse of autologous breast reconstruction. The main drawback most surgeons have with this option is in the donor site morbidity. Very often, the rectus sheath cannot be closed primarily and the defect has to be bridged using a mesh. Even if the rectus sheath can be apposed, the patient is at risk of having an abdominal hernia from weakness of the abdominal wall. The ideal situation would be to use a non-permanent on-lay graft over the primary repair to strengthen the sheath repair. The graft would give additional strength until fibrosis has set in to provide the additional strength to the repair, and yet the mesh would then resorb, to minimize the problems associated with the use of a permanent mesh.

40 patients in total were recuited. 20 for the study group where TIGR ® Matrix was implanted, the other 20 served as controls. All patients were randomized into either using this synthetic resorbable mesh or a synthetic permanent mesh. Data was collected prospectively, as well as on follow up up to 1 year.

The results showed that there was no significant difference in complication rates between the two groups, up to a follow up of 1 year. There was no difference in patient recovery, hospitalization stay, and pain scores.

TIGR® Matrix Surgical Mesh may be a suitable resorbable on-lay mesh for use in repair of the rectus sheath after TRAM flap surgery.
