Clinical effect of single covered stent and double covered stent in transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of hemorrhage due to rupture of esophageal and gastric varices in cirrhosis and its influence on the immune function of patients was investigated. Altogether 124 patients with liver cirrhosis and esophageal and gastric varices bleeding who were admitted to the First People's Hospital of Neijiang from February 2012 to April 2016 were selected as research objects and divided into group A and B. Group A (65 cases) was treated with simple covered stent, and group B (59 cases) was treated with double covered stent simulating Viatorr technique. The therapeutic effect of the two groups after operation was observed. The changes of portal vein pressure before and after treatment and the changes of esophageal and gastric varices after operation were observed. The levels of peripheral blood T lymphocyte subsets (CD3 + , CD4 + and CD4 + /CD8 + ) were detected by flow cytometry. The therapeutic effect of group B was higher than that of group A (P&gt;0.05). The postoperative portal vein pressure in group B was significantly lower than that in group A (P&lt;0.05). The disappearance rate and overall effective rate of varicose veins in group B were better than those in group A (P&gt;0.05). After three days of treatment, the levels of CD3 + , CD4 + , CD4 + /CD8 + in the peripheral blood of group B were higher than those of group A (P&gt;0.05), while the decline rate of CD3 + , CD4 + , CD4 + /CD8 + in the peripheral blood of group B was higher than that of group A after seven days of treatment. Double-stent simulated Viatorr has a higher effective rate, has a certain improvement on the immune function of patients, and the survival rate is also higher than that of single covered stent, which is worthy of clinical application and promotion.
