Experimental Modeling of Atypical Extremely Extensive Liver Resection

We propose an original model of atypical extremely extensive liver resection applicable for studying of the mechanisms of early and late hepatic and extrahepatic postoperative complications. After median laparotomy and mobilization of the middle and left lobes of the liver, 2-4 mattress sutures were applied to each lobe paracavally and 1 mm proximal to the proposed line of resection, the lobe parenchyma was cut off, and electrocoagulation of the wound surface was performed; the removed part was equivalent to 80% of the liver weight. This model of liver resection was used to study the pathogenetic factors of circulatory insufficiency in the postoperative period.
