METHOD FOR TREATING BILATERAL PERINEAL HERNIA IN DOGS Russian patent published in 2024 - IPC A61B17/00 A61F2/08 

FIELD: medicine; veterinary surgery.

SUBSTANCE: dog is placed on the operating table in the dorsal position. General anaesthesia is performed, the hernia defect is identified by external palpation, and the size of the pelvic floor hernia defect is determined. After that, a mesh implant made of polypropylene is cut out, larger than the hernia defect by 1-2 cm around the perimeter. The hernia defect is closed with an implant and the mesh implant is secured with non-absorbable sutures around the hernia defect. The dog is fixed on the table with the pelvic limbs retracted forward and caudal part raised by 30-35°. Afterwards, the surgical field is prepared, surgical access is carried out in form of two parallel incisions to the right and left of the anal sphincter, medial to the palpable caudal edge of the ilium, and preparation of the subcutaneous tissue in the area of the hernial sac. The adhesions of the organs of the abdominal and pelvic cavities are separated from the remains of the structures of the perineal floor, and the organs of the abdominal and pelvic cavities are repositioned. After that the implant is inserted through the left incision and passed to the right, removing its edge from the wound. The implanted mesh is distributed over the entire area of the hernia defect and fixed with non-absorbable suture material along the perimeter of the hernial opening to the remnants of the aponeurosis of the obturator muscle, the muscles of the anal sphincter, the depressor of the tail and the aponeuroses of the muscles of the posterofemoral group. The operation is completed by suturing the subcutaneous tissue with its fixation to the implant and suturing the skin wounds.

EFFECT: method ensures unimpeded performance of the entire complex of surgical procedures, including preparation of the subcutaneous tissue in the area of the hernial sac, separation of the adhesions of the abdominal and pelvic organs from the remains of the parietal peritoneum with the omentum and subcutaneous tissue, reposition of the displaced organs to their anatomically correct position, closure of the hernia defect with a prepared implant and suturing surgical wounds, due to the proposed method of fixing the animal and surgical access in form of two parallel incisions.
