▪ ABSTRACT

Introduction:

Reducing recurrence rates significantly, the use of biomaterials as “reinforcement meshes” in the repair of different abdominal wall defects has become an almost mandatory routine for the success of these repairs. From the 1990s onwards, acellular biological matrices were introduced, thus beginning a new era in the repair of abdominal wall defects. The objective is to evaluate the functionality of the acellularized bovine pericardium in abdominal wall repairs.

Method:

Thirty patients underwent repair of abdominal wall defects using acellular bovine pericardium bioprostheses, making a total of 40 anatomically individualized implants. The average follow-up was 31 months, with patients being evaluated clinically and radiologically. In three cases, biopsies were taken from the implanted areas, allowing histological analysis of the material.

Results:

No recurrence of herniations was observed in any of the cases, both clinically and radiologically. There were also no records of bruises, infections or any phenomenon of a local or systemic reaction nature. Radiologically, it was not possible to visualize the matrices at the implantation site in any of the postoperative periods analyzed.

Conclusion:

The matrices showed similarity to other biological membranes described in the international literature. Representing an important update and conceptual evolution, acellular bovine pericardial membranes can be incorporated into the therapeutic arsenal in abdominal wall repairs.
