Abstract:〔Abstract〕 Objective To explore the effect of Xiaoyan Lidan tablet on serum inflammatory factor level and prognosis of patients with acute cholecystitis after laparoscopic operation. Methods Sixty-eight patients with acute cholecystitis admitted to the Second People's Hospital of Yichun from June 2019 to June 2022 were selected and divided into a control group and an observation group according to random number table method, with 34 cases in each group. Both groups were treated with laparoscopic cholecystectomy. The control group was given anti-infection treatment with levofloxacin tablet after surgery, and the observation group was given Xiaoyan Lidan tablet on the basis of the control group for 2 weeks. The clinical efficacy, serum levels of inflammatory factors and occurrence of complications were compared between the two groups. Results The total clinical efficacy rate of the observation group was higher than that of the control group, and the difference was statistically significant (P < 0.05). After treatment, the levels of serum procalcitonin (PCT), C-reactive protein (CRP) and interleukin-6 (IL-6) in the observation group were lower than those in the control group, with statistical significance (P < 0.05). The total incidence of complications in the observation group was lower than that in the control group, and the difference was statistically significant (P < 0.05). Conclusion The effect of Xiaoyan Lidan tablet in the postoperative treatment of patients with acute cholecystitis undergoing laparoscopic surgery is significant, which is conducive to improving the inflammatory response of the body, reducing the incidence of complications, promoting the prognosis of patients, and has high clinical safety.
