Description of an experimental model of two-stage hepatectomy in different extents of cholestasis

Abstract

divided the dissection is pursued following the direction of the common hepatic artery on its anterior surface. The origin of the splenic and gastroduodenal artery are identified and encircled. The inferior mesenteric vein is canulated. Gastrocolic ligament is then opened and the pancreas is exposed. We perform complete mobilisation of the inferior pancreatic border up to the spleen. Methods: In the cold phase we complete bile duct and gastroduodenal artery section. Common hepatic artery is completely freed from superior pancreatic border. Splenic artery is divided 1 cm after its origin. Abdominal aorta is then transected between celiac trunk and superior mesenteric artery. Results: Portal vein is fully exposed in order to exclude the presence of a right hepatic artery coming from superior mesenteric artery. Portal vein is then divided in the middle of the hepatic pedicle. Liver is then harvested. The duodenum is divided proximally and distally with a linear stapler. The origin of the mesenteric rooth is identified and then stapled. Conclusion: The pancreas is fully mobilised on its posterior aspect from its attachment. The dissection ends with short gastric vessels division and finally the pancreas is removed en-bloc with the spleen.
