Abstract

The management of abdominal wall repair continues to present a challenging problem, especially in the repair of major defects. Many abdominal wall defects can be repaired by primary closure; however, if the defect is large and there is a tension on the closure of the wound, the use of prosthetic materials becomes indispensable. Many studies have been performed with various materials and implant techniques, without the comparison of their degrees of success, based on sound meta-analysis and/or inclusive epidemiologic studies. This review covered the effectiveness of recent advances in prosthetic materials and implant procedures used in repair of abdominal wall, based on biomechanical properties and economic aspects of reconstructed large abdominal wall defects and hernias in animals. The presented results in this review helped to reach treatment algorithms that could maximize outcomes and minimize morbidity.

Highlights

The abdomen is a very delicate part of the body of animals
Many abdominal wall defects and hernias can be repaired by a primary closure while massive defects, including irreducible hernia, need special attention, since they cannot be treated by simple methods of reduction
Glycerin was able to preserve the bovine pericardium grafts in abdominal wall repair of rats, showing a reduced amount of abdominal viscera adhesion and more implant incorporation with the host tissue in comparison to that of the polyester mesh [38]

Summary

Introduction

The abdomen is a very delicate part of the body of animals. It is subjected to trauma and clinical disorders. Many abdominal wall defects and hernias can be repaired by a primary closure while massive defects, including irreducible hernia, need special attention, since they cannot be treated by simple methods of reduction This type of hernia requires surgical procedures to rectify the defect by the use of graft [2]. The mesh is known to augment the strength of the weakened abdominal wall fascia and to enable the hernia repair under a tension-free condition This surgical procedure could be associated with a risk of infection, fistula formation, and possibility of presence of chronic abdominal wall pain. In avoidance of these postoperative injuries, surgeons are directing their efforts towards the use of xenogenic and allogenic materials for the repair of abdominal wall defects [4]. The use of biomaterial for the repair of abdominal wall defects has gained an increasing recognition in achieving a tension-free repair, resulting in a significant reduction of postoperative pain, shortening the recovery period, and the frequency of recurrence [7]
