Non-contact MCE Examination
After an overnight fasting and drinking 1000 mL water and simethicone for gastric dilatation and preparation, the study subject positions himself (herself) on the examination bed in Room A, while the operating doctor sits in Room B at the remote control workstation instructing her to swallow the capsule via the audio-visual exchange system. After the capsule entering the stomach, the doctor manipulated the two joysticks on the remote control workstation, mobilizing the robotic magnetic arm, and simultaneously driving the precise movement and rotation of the capsule to perform the gastric examination. In order to simplify the examination procedure, the data recorder was put on the examination bed. The patient lay down after swallowing the capsule under the remote guidance of the endoscopist. non-contact magnetically-controlled capsule endoscopy: The novel non-contact magnetically-controlled capsule endoscopy (MCE) system (Ankon Technologies, Wuhan, China) (Figure 1) added a remote control workstation and an audio-visual exchange system to the original well-establish MCE system, which consisted of a robotic magnetic arm, a workstation (currently bypassed) and a capsule endoscope.
MCE Examination
After an overnight fasting and drinking 1000 mL water and simethicone for gastric dilatation and preparation, the subjects put on the data recorder with the help of an endoscopist. Then, the endoscopist activated the capsule with the capsule locator. The patient was instructed to assume the supine or left lateral decubitus position and to swallow the capsule with a small amount of water to effectively observe the esophagus and dentate line. Then, under the guidance of the endoscopist face to face, the subject turned over on the bed to complete the examination. non-contact magnetically-controlled capsule endoscopy: The novel non-contact magnetically-controlled capsule endoscopy (MCE) system (Ankon Technologies, Wuhan, China) (Figure 1) added a remote control workstation and an audio-visual exchange system to the original well-establish MCE system, which consisted of a robotic magnetic arm, a workstation (currently bypassed) and a capsule endoscope.

To simplify the preparation process, we embedded the data recorder in the examination bed. The ncMCE system separates endoscopists and patients in two rooms (control room for the endoscopist and examination room for patients), offering physical isolation for noninvasive gastric examination during the pandemic.

SECONDARY outcome

Timeframe: During the procedure

Maneuverability score was the sum of four subjective scores rated by the operator (signal transmission quality score, operating comfort score, gastric visualization score and study subject compliance score), each of which ranged from 1 to 5 denoting the lowest to the highest degree of satisfaction and the range of total score from 0 to 20. The higher the score, the better the maneuverability.

Timeframe: After the procedure(within 5 days)

The investigators use a satisfaction questionnaire to evaluate the comfort and acceptability of each patient by two sub questionnaires, which was pre-procedure patient perception (3 items, ranged from 0 to 12 ) and post-procedure patient satisfaction (12 items, ranged from 0 to 48) .The higher the score, the worse the patient's satisfaction.
