The patients were enrolled according to the research criteria, and collected the general basic information of the patients. After the preoperative preparation was perfected, the same surgical team performed laparoscopic splenectomy, and the same nursing team performed the nursing after the operation. Then, patients received a unified treatment plan after surgery, including medication, other treatments and follow-up. During the treatment, the liver reserve function related indicators of the patients were monitored before surgery, 3, 6, 12 and 24 months after surgery, including TBIL, DBIL, ALB, ALT, INR, PT, Child-Pugh, ascites, prealbumin, ICG-K, ICG-R 15 and ICG-T/2.
