Abstract:Objective Through the collection of magnetron capsule endoscopy patients data, the detection rate of magnetron capsule endoscopy in the upper gastrointestinal tumor was obtained, the application value of magnetron capsule endoscopy in the screening of upper gastrointestinal tumors and other lesions was studied. The population characteristics and reasons for selecting magnetron capsule endoscopy patients were analyzed, so as to provide a basis for the further promotion of the examination.Methods Retrospectively collect the information of magnetron capsule endoscopy patients from November 2020 to December 2021, if detect suspected upper gastrointestinal tumors,further confirmed by gastroscopic biopsy pathology, and through the “Magnetron Capsule Endoscopy Selection Intention Questionnaire” to collect the basic information and reasons for patients who selected capsule endoscopic, and apply SPSS 25.0 statistics and analysis data.Results The detection rate of upper gastrointestinal tumors in the magnetron capsule endoscopy of our hospital was 2.04% (1/49), detection rate of atrophic gastritis was 10.20% (5/49), detection rate of gastric ulcers 4.08% (2/49), detection rate of gastric polyps 8.16% (4/49). The reasons why patients choose magnetron capsule endoscopy are mainly due to three reasons, such as fear of gastroscopy (34.69%, 17/49), a test that can achieve gastrointestinal and intestinal examination (34.69%, 17/49), and the physical examination does not require a painful examination like gastroscopy (36.73%, 18/49).Conclusion Magnetron capsule endoscopy played an important screening role in patients who are afraid of gastroscopy,or existing diseases or other conditions that gastroscopy cannot be achieved. And magnetron capsule endoscopy is an important supplement to gastroscopy.
