Correlation of endoscopy findings with symptoms in patients undergoing gastroscopy: a prospective study / 中华消化内镜杂志

ABSTRACT

Objective:To investigate the correlation of endoscopy findings with symptoms in patients undergoing gastroscopy.Methods:Patients who underwent gastroscopy for the first time in Renji Hospital of Shanghai Jiao Tong University School of Medicine from January to December 2017 were included in the questionnaire survey. The participants were asked to report their main symptoms of the digestive tract in details, and gastroscopy was completed within 2 weeks. Final gastroscopic diagnosis was made based on both gastroscopy and pathology, then patients were divided into the major-lesion (peptic ulcer and malignancy) group and the non-major-lesion (chronic gastritis, reflux esophagitis and others) group. The correlation of gastrointestinal symptoms with gastroscopic findings was analyzed. The risk for major gastroscopic lesions (peptic ulcer and malignant tumors) was assessed by multivariate Logistic regression analysis.Results:A total of 5 885 patients completed the questionnaire, 5 496 (93.4%) of whom completed gastroscopy. The detection rates of peptic ulcer were 12.3% (373/3 028), 12.6% (52/412), 17.9% (49/273), 9.5% (64/675) and 9.2% (102/1 108) in patients with dyspepsia, reflux, alarm, other symptoms and no symptoms, respectively, the detection rates of malignant tumors were 1.2% (36/3 028), 0.7% (3/412), 7.7% (21/273), 0.7% (5/675) and 0.4% (4/1 108), respectively in these patients. The most common symptoms was dyspepsia, accounted for 58.3% (373/640) and 52.2% (36/69) patients with peptic ulcer and malignant tumors, respectively. Alarm symptoms were found in 30.4% (21/69) patients with malignant tumors, and 15.9% (102/640) peptic ulcer patients and 5.8% (4/69) malignant tumor patients had no gastrointestinal symptoms. Compared to asymptomatic individuals, patients with dyspepsia ( P<0.001, OR=1.52, 95% CI 1.21-1.92) and those with warning symptoms ( P<0.001, OR=2.87, 95% CI 2.02-4.08) had significantly increased risk for major lesions (peptic ulcer and malignant tumors) detected by gastroscopy. Conclusion:Although dyspepsia and alarm symptoms are positively associated with upper gastrointestinal malignancy and peptic ulcer, they are of limited predictive value for upper gastrointestinal diseases.
