Twenty-one patients(male 18 cases,femal 3 cases)died of primary liver cancer after operation are reviewed.The liver tumors were located in the right lobe(13 cases),left lobe(3 cases),middle position of liver(4 cases)and hepatic hilum(1 cases).The average diameter of the tumors were 9.0cm.All the patients had suffered from liver cirrhosis and were operated on (most of them partial hepatectomy).The times of death were about 7 days,7-14 days later after operation.The data suggest that causes of death were different from the different stage after operation.The relations between partial hepatectomy and hepatic failure,and the liver cirrhosis and liver regeneration are discussed.
The main treatment strategies for hepatic failure include drug therapy, artificial liver support system, and liver transplantation. This article introduces the clinically commonly used non biological artificial liver techniques, including plasma exchange, continuous blood purification, plasma bilirubin adsorption, plasma diafiltration, repeatedly pass albumin dialysis, molecular adsorbent recirculating system, Prometheus system, etc; and discusses how to select different artificial liver techniques according to different clinical manifestation. At the same time, the progress of bioartificial liver in recent years is summarized, and the future development of artificial liver is prospected.
