Study on the construction of a column chart model for recurrence after endoscopic high-frequency resection of intestinal polyps
Objective:To establish an individualized risk prediction model for recurrence after endoscopic high-frequency resection of intestinal polyps.Method:A risk prediction model for recurrence after endoscopic high-frequency resection of intestinal polyps was established based on 340 patients with intestinal polyps who underwent high-frequency resection.The logistic regression analysis showed that age≥60 years,number of intestinal polyps≥3,diameter of intestinal polyps≥2cm,adenomatous intestinal polyps,smoking history,and metabolic syndrome were risk factors for postoperative recurrence in patients undergoing endoscopic high-frequency electrical resection.Based on this,a column chart model was constructed with a C-statistic index of 0.831,and the calibration curve and standard curve had a good fit.Conclusion:Age≥60 years old,number of intestinal polyps≥3,diameter of intestinal polyps≥2 cm,adenomatous intestinal polyps,smoking history,and metabolic syndrome are risk factors for postoperative recurrence in patients with intestinal polyps undergoing endoscopic high-frequency electrical resection.The column chart model constructed based on this has good predictive performance.
