Objective: To observe the clinical efficacy of octreotide and thrombin in the treatment of patients with liver cirrhosis, and to explore the mechanism of octreotide and thrombin. Methods: 53 patients with cirrhosis were randomly divided into control group and observation group from January 2014 to January 2016. The control group of 26 patients, given octreotide treatment. Observation group of 27 cases, given octreotide and thrombin combination therapy. Comparison of two groups of patients with clinical efficacy and changes in liver function before and after treatment. Results: The effective rate (88.89%) in the observation group was significantly higher than that in the control group (65.38%), the difference was statistically significant (p < 0.05). Before treatment, the difference of liver function between the two groups was not statistically significant (p > 0.05). After treatment, the liver function indexes of the two groups were improved, and the observation group was superior to the control group, the difference was statistically significant (p < 0.05).
