Economic and clinical evaluation of the surgical technique of overlapping in bovine umbilical hernia

Abstract

The objective was to evaluate clinically and economically the surgical technique of overlapping to correct umbilical hernia as a productive strategy in bovine production companies. The investigation was of a descriptive experimental type. 15 bovines (2 males and 13 females), average weight 73 kg, hernial ring with diameter ≤10 and ≥ 6 centimeters were used. An elliptical incision with a cranial and caudal extension of 1-2 cm was made with respect to the hernial ring; it was continued through the layers of the areolar connective tissue to the hernial sac, dissected and left free until the margin of the ring. Subsequently, the edges of the hernial ring were revived with an extended cut of 1-1.5 cm around it. The abdominal muscles were closed using modified Mayo overlapping sutures. Sufficient stitches were made until total reduction of the hernial ring. The skin was closed with suture interrupted with nylon. The indicators show that the overlapping surgical technique was efficient, obtaining a high Cost Benefit Ratio of 4.6, and an improvement in the calves at 24 days for their zootechnical function.
