Abstract
Role of Bovine Amniotic Membrane in Repair of Abdominal Muscle Defects in Dogs
Highlights
IntroductionAbdominal wall hernia repair using polypropylene mesh (PP) in dogs was first described by Usher and Wallace (1958)
A circular full-thickness ventral abdominal wall defect about 5 cm in diameter was created in the muscles and peritoneum
In group A, PP mesh alone was used for hernioplasty, whereas in group (B) PP was combined with bovine amniotic membrane (BAM) and in group (C) dogs were treated with PP and omentalization
Summary
Abdominal wall hernia repair using polypropylene mesh (PP) in dogs was first described by Usher and Wallace (1958). Hernioplasty was popularized, other types of meshes were developed, and new techniques were used to overcome the serious complications caused by PP such as recurrence, bowel adherence and obstruction, fistula formation, wound infection, and seroma/hematoma (Lasonoff and Sauter, 2004). Adhesions are defined as fibrous structures in the abdominal cavity that arise at injured peritoneal surfaces as a consequence of disturbed tissue repair after peritoneal trauma. To prevent adhesion formation, during hernioplasty, a mechanical barrier is used to cover the mesh over the hernia. This is combined with systemic injections of anti-inflammatory drugs, antihistamines, and fibrinolytic agents such as citrate or heparin. The barrier lasts for at least seven days until the completion of the healing process and is absorbed by the body (Farquhar et al, 2000)
