Polypropylene mesh versus nylon mosquito net mesh for external abdominal hernias repair in cattle and buffaloes

Abstract

Herein, the effectiveness of locally sourced and autoclaved nylon mosquito net mesh for the repair of external abdominal hernias was investigated. Eleven animals (7 cattle and 4 buffaloes) having hernial ring sizes of 8 to 30 cm in diameter were divided into two Groups 1 (5 animals) and Group 2 (6 animals). In Group 1, nylon mosquito net mesh was used, and in Group 2, polypropylene mesh was used for the repair of defects. The animals were sedated with xylazine HCl and given local anaesthesia during surgery. Over the external hernial sac, an elliptical skin incision was made. The internal hernial sac was bluntly dissected and freed down to the hernial ring. The internal hernial sac was opened, and the hernial ring was repaired with nylon mosquito net mesh or polypropylene mesh using the inlay technique. After hernioplasty, the sac and subcutaneous tissue were repaired with prolene suture material. The skin incision was closed with simple interrupted mattress sutures using monofilament polyamide suture material. Antibiotics and analgesics were given postoperatively, and povidone iodine was used to treat the suture line daily. The skin sutures were removed on the 10^th to 15^th postoperative day, depending upon the wound condition. Mild inflammatory swelling in Group 1 was observed at the incision line, which had completely subsided by the 15^th postoperative day. The wounds healed by first intention in both groups. In any case, no recurrence was seen in a follow-up period of 3 months. Without clinical signs of wound dehiscence, infection, or recurrence, all animals recovered uneventfully.
