Abstract
The efficacy of intelligent thermofusion sealing in spaying and neutering operations was evaluated in comparison to ligature sealing. The postoperative inflammatory reactions were quantitatively determined by the C-reactive protein (CRP) levels measured by laser nephelometric immunoassay. The 5-109 month-old healthy dogs clinically received orchiectmy or ovariectmy. The half of the 50 male patients underwent the intelligent thermofusion sealing of the testicular vascular plexuses and the deferent canals and the other half did ligation with absorbable polydioxanone sutures. The half of the 50 female patients underwent the intelligent thermofusion method for the ovarian vascular plexuses and the suspensory ligament sealing and the other half did ligation with nonabsorbable polyester sutures. The intelligent thermofusion sealing was performed with BiClamp® 150 and 200 instruments and VIO 300D generator. The intelligent thermofusion sealing method has significantly lower CRP values than those values of ligatation in both orchiectomy and ovariectomy. The lower values implied the milder acute inflammation ascribed to the shortened operative time and the decrease of the hemorrhage amounts. The intelligent thermofusion sealing was proved to be a low invasive surgical procedure free from suture-reactive conglutination and granuloma.
