A MODIFIED TECHNIQUE FOR IMPLANTATION OF POLYPROPYLENE MESH FOR THE REPAIR OF EXTERNAL ABDOMINAL-HERNIAS IN HORSES - A REVIEW OF 21 CASES

During a 3-year period 21 horses were surgically treated because of large abdominal wall defects. In each case the defect was bridged with a polypropylene mesh, which was placed on the outside of the hernial ring. This was in contrast with the technique for mesh herniorrhaphy generally described in human and veterinary literature, in which the mesh is always implanted on the inside of the hernial ring. One horse was destroyed on the first postoperative day because of postanaesthetic myelomalacia. Surgical repair as described was successful in 18 patients. Recurrence of herniation occurred in two horses. On re-herniorrhaphy a second and larger mesh was successfully implanted.
