The liver, the largest glandular tissue of the body, can be affected by localized conditions, such as neoplasia, abscesses and lobe torsion, which is indicated partial hepatectomy or lobectomy. In this experiment, it was evaluated the applicability and safety of a modified form of guillotine ligature method for the complete hepatic lobectomy in cats. Thirteen adult male mixed and clinically healthy cats were used. The modified guillotine ligature method was used in the base of the left lateral lobe of the liver, promoting the hemostasis of the organ by crushing the tissues. At postoperative period, several clinical parameters were appraised during 10 days, and 11 days after the surgery the ultrasonographic evaluation was made. The evaluated clinical parameters stayed within the physiologic limits, showing the absence of important complications due to surgery. In the modified guillotine method the base of the hepatic lobe was divided in three segments, allowing the ligature to crush through the hepatic parenchyma. As the ligature tears the hepatic tissue, blood vessels and biliary ducts were adequately ligated, and no hemorrhage or ascites was observed in the clinical and ultrasonographic exams. At 11 days after the lobectomy, the livers appear ultrasonographicaly normal with small hiperechogenic area in the place of the ligatures, suggesting cicatricial tissue. The modified guillotine ligature method was considered safety and with low morbidity for the hepatic lobectomy in cats.
