The invention of magnetically controlled capsule gastroscopy makes the movement of capsule endoscope in the body controllable. Endoscopic doctors can adjust the angle of capsule observation to examine gastric mucosa according to the need of examination. However, The presence of food residue, air bubbles, mucus and bile in the gastric cavity will affect the observation of gastric mucosa by capsule endoscopy. it will reduce the completion rate of capsule endoscopy, and even lead to misdiagnosis and missed diagnosis. The purpose of this study is to explore the factors affecting the quality of gastroscopy gastric environmental preparation of magnetically capsule.

Primary | GCS score was used to evaluate the quality of gastric preparation | GCS score was used to evaluate the quality of gastric preparation. GCS was defined as the sum of the scores of six major anatomical markers of the stomach (heart, fundus, body, horn, sinus, and pylorus).A 4-point grading system was used to define cleanliness as excellent (no mucus and foam attachment :4 points);Good (there is a small amount of mucus and foam, but it does not affect the test: score 3 points);Average (with a fair amount of mucus or foam).Failure to complete a completely reliable examination :2 points);Poor (large amount of mucus or foam residue :1 point).The GCS is the total score for all six landmarks, ranging from 6 (completely unprepared) to 24 (perfect).Gastric preparation was defined as sufficient when GCS=18 and insufficient when GCS<18. | 24 months | |
Primary | Questionnaire data were used to analyze the influencing factors | Before the examination, the subjects were required to fill in a questionnaire about the influencing factors of the quality of stomach preparation. According to GCS, the subjects were divided into fully prepared group and inadequately prepared group. Finally, statistical analysis was used to find the influencing factors that had statistical significance with the quality of stomach preparation according to the questionnaire content. | 24 months | |
Secondary | The number of positive lesions | The positive lesions detected in this study refer to some focal lesions of the stomach, including polyps, ulcers, gastric varices, submucosal tumors and so on.The lesions were identified by physicians who had performed magnetic capsule gastroscopy in more than 400 cases. | 24 months | |
Secondary | Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 | The safety of MCCG includes the acceptability or adverse events of MCCG preparation and examination, which is defined as symptoms or signs such as drinking water, examination and swallowing capsules, such as monitoring abdominal distension, nausea or vomiting.we count the number of participants with treatment-related adverse events as assessed by CTCAE v5.0 | 24 months |
