AbstractTo explore the risk factors of postoperative fever in elderly patients undergoing endoscopic submucosal dissection (ESD). A total of 439 patients who met the inclusion criteria were enrolled in this study and randomly divided into training (n = 311) and validation (n = 128) cohorts at a ratio of 7:3. Independent risk factors were screened by single-factor and multiple-factor logistic regression analyses, and a nomogram was established using them. The nomogram was evaluated using receiver operating characteristic curve analysis, decision curve analysis, and calibration plot using the "rms" package in R software (R4.2.1). The study included 439 patients. Female (OR = 2.55, 95% CI: 1.5-4.33), diabetes (OR = 2.38, 95% CI: 1.17-4.85), operation time (OR = 1.01, 95% CI: 1-1.02) were lesion located in the esophagus (OR = 2.37, 95% CI: 1.44-3.88), maximum tumor diameter (OR = 1.3, 95% CI: 1.07-1.57), and placement of a urinary catheter (OR = 7.09, 95%CI: 1.43-35.17) were independent risk factors for postoperative fever in elderly ESD patients (P < .05). Female sex, diabetes, lesions located in the esophagus, lesion size, operation time, and placement of a urinary catheter are risk factors for postoperative fever in ESD patients, and patients with these risk factors should be vigilant for postoperative fever and receive appropriate treatment.Copyright © 2023 the Author(s).
