Background: Stomach depressed lesions are very common in clinics, and gastric depressed lesions may be gastric ulcers or gastric cancer. Despite the abundance of available detection methods, there are still a lot of problems in the identification of early gastric cancer. Therefore, it is necessary to analyze the value of endoscopy in the differential diagnosis of patients with gastric depression. This article aimed to study the value of confocal microendoscopy in the differential diagnosis of patients with gastric depressed lesions.
Methods: The research subjects were patients with gastric depressed lesions admitted to our hospital who were investigated based on the biopsy results, the accuracy, misdiagnosis rate, missed diagnosis rate, sensitivity, and specificity of confocal microendoscopy. Through data analysis, the influence of ulcer size on the diagnosis result was also studied, and the reasons for misdiagnosis were analyzed.
Result: The results of the study showed that the sensitivity and specificity of confocal microendoscopy for gastric depressed lesions were higher than the other two methods, reaching 83.4% and 99.1%, respectively, and the diagnostic accuracy rate reached 96.2%. It can be seen that confocal microendoscopy has obvious advantages in the diagnosis of gastric depression.
Conclusion: The ulcer size of gastric depressed lesions has a relatively obvious impact on the accuracy of diagnosis. The misdiagnosis rate of benign ulcers and malignant ulcers both decreases with the increase in ulcer diameter.
