Analysis of risk factors for incomplete whole small intestine examination by capsule endoscopy / 中国综合临床

ABSTRACT

Objective:To explore the clinical characteristics and risk factors of incomplete endoscopy of small intestine capsule.Methods:From August 2015 to February 2019, the data of 282 patients with small intestine examination by capsule endoscopy in Affiliated Hospital of Xuzhou Medical University were analyzed retrospectively.The clinical and laboratory examination data were statistically analyzed.The risk factors of incomplete small intestine examination were analyzed by multivariate logistic regression.Results:In all 282 patients, 45 cases did not complete the examination, the incomplete rate was 16.0% (45/282). Multivariate analysis showed that male ( OR=3.261, 95% CI1.084-9.815, P=0.035), age (64.78±13.23) years ( OR=1.046, 95% CI1.007-1.086, P=0.020), intragastric time (59.78 (27.89, 108.67)) min ( OR=1.014, 95% CI1.005-1.024, P=0.004), gastrointestinal bleeding ( OR=3.017, 95% CI1.025-8.880, P=0.045), abdominal operation history ( OR=4.902, 95% CI1.553-15.470, P=0.007) were risk factors for incomplete examination.Hemoglobin (95.20±26.16) g/L( OR=0.977, 95% CI0.957-0.998, P=0.033), albumin (35.73±7.11) g/L( OR=0.871, 95% CI0.790-0.961, P=0.006) were protective factors for incomplete examination. Conclusion:Male, age, intragastric time, gastrointestinal hemorrhage and abdominal operation history were risk factors for incomplete small bowel examination with capsule endoscopy, and hemoglobin and albumin were protective factors.Before capsule endoscopy, patients should not only evaluate the intestinal stenosis, but also pay attention to the nutritional status and clinical symptoms of patients, so as to improve the completion rate of patients.
