Methods: 80 patients with internal hemorrhoids admitted to our hospital from April 2021 to April 2022 were randomly divided into the experimental group and the reference group (40 cases in each group) by double-blind method. The reference group was treated with conventional surgery, while the experimental group was treated with sclerosing agent of polyglycerol under endoscope. The therapeutic effects, pain conditions at different stages after treatment, perioperative inflammatory status indicators and perioperative complication rate of the two groups were statistically compared. Results: after treatment, the total effective rate of the experimental group was higher than that of the reference group, the VAS score of the experimental group was lower than that of the reference group at different stages in the early postoperative period, the inflammatory indexes such as CRP and PCT of the experimental group were lower than that of the reference group at 7 days after operation, and the perioperative incidence rate was lower than that of the reference group, with statistical significance (p 0.05). Conclusion: the curative effect of endoscopic sclerotherapy with poly (laurel alcohol) for internal hemorrhoids patients is definite, the postoperative pain response is relatively mild, and it is helpful to promote the improvement of postoperative inflammatory state and reduce the risk of complications.展开更多
