Abstract:Objective To explore the efficacy and prognostic factors of endoscopic sclerosing agent injection combined with ligation in treatment of patients with internal hemorrhoid.Methods 150 patients with internal hemorrhoid from January 2018 to June 2021 were prospectatively included and divided into control group (endoscopic ligation alone) and observation group (endoscopic sclerosing agent injection combined ligation treatment) by random number table method, with 75 cases in each group. The clinical efficacy, operation situation and incidence of postoperative complications were compared. According to the prognosis, patients were divided into good prognosis group and poor prognosis group. Multivariate Logistic regression was used to screen the influencing factors of poor prognosis, build a risk prediction model and evaluate the effectiveness of the model.Results The total cure rate of observation group was significantly higher than that of control group, the operation time was significantly longer than that of control group, while the intraoperative blood loss was significantly less than that of control group, visual analogue scale (VAS) and the total incidence of postoperative complications were significantly lower than those of control group, the healing time was significantly shorter than that of control group, the differences were statistically significant (P < 0.05). Multivariate Logistic analysis showed that age, course of disease, severity of disease, dietary habits, intraoperative blood loss and defecation time were independent risk factors for poor prognosis of patients with internal hemorrhoid after treatment (P < 0.05). The nomogram prediction model had higher discrimination and calibration degree.Conclusion In the treatment of internal hemorrhoids, endoscopic ssclerosing agent injection combined with ligation has better efficacy and fewer complications than endoscopic ligation alone. Advanced age, long course of disease, serious condition, spicy diet, large amount of intraoperative blood loss and premature defecation after operation are the influencing factors of poor prognosis of patients with internal hemorrhoid. Clinical attention should be paid to these patients.
