Incidence and risk factors for fever after endoscopic submucosal dissection and its derivative technology for gastric lesions.

INTRODUCTION

Fever is one of the postoperative complications of endoscopic submucosal dissection (ESD) and its derivative technology. However, there are few studies on risk factors for fever after ESD and its derivative technology. The aim of this study was to determine the incidence and related risk factors after ESD and its derivative technology for gastric lesions.

MATERIALS AND METHODS

A retrospective review of patients with gastric lesions who were treated by ESD and its derivative technology in our hospital from January 2014 to January 2019 was conducted.

RESULTS

A total of 1955 patients were included in the present study. A total of 451 (23.1 %) patients presented with fever after ESD and its derived techniques. The highest fever temperature was 37.6 ± 3.12 °C, and the number of days with fever was 1.48 ± 0.85. Through single factor and multiple factor analysis, age (OR: 1.261, 95% CI: 1.009-1.576, p < 0.05), procedure time (OR: 1.457, 95% CI: 1.053-2.016, p < 0.05), postoperative gastric tube placement (OR: 2.098, 95% CI: 1:616-2.723, p < 0.05), intraoperative hemorrhage (OR: 1.537, 95% CI: 1.196-1.974, p < 0.05) and perforation (OR: 1.970, 95% CI: 1.531-2.535, p < 0.05) were independent risk factors for postoperative fever.

CONCLUSION

Age ≥56 years old, procedure time ≥60 min, gastric tube placement, intraoperative hemorrhage and perforation were independent risk factors for postoperative fever after gastric ESD and its derivative technology. Attention should be given to such patients to minimize the risk of postoperative fever.
