About

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in the world, accounting for the second leading cause of cancer death in China.Surgical treatment of hepatocellular carcinoma is the most important means for long-term survival of patients with hepatocellular carcinoma, including hepatectomy and liver transplantation.Chronic liver disease caused by hepatitis B infection is the main pathogenic factor of liver cancer in China. Meanwhile, nearly 80% of patients with hepatocellular carcinoma are complicated with cirrhosis, and the incidence of thrombocytopenia in patients with cirrhosis is reported to be as high as 78%.Many previous studies have found that thrombocytopenia is closely related to perioperative outcome of hepatocellular carcinoma.The purpose of this study was to evaluate the efficacy and safety of avatripopa in the treatment of thrombocytopenia in patients with primary hepatocellular carcinoma undergoing elective hepatectomy and its effect on perioperative outcome.

Full description

The indicators included changes in platelet count before and after drug treatment and operation, the nature and amount of postoperative drainage (ascites), duration of indwelling drainage tube, intraoperative blood loss, perioperative complications, length of hospital stay, etc.After comprehensive consideration of all perioperative indicators, we selected the total amount of drainage (ascites) multiple days after surgery as the primary outcome.
