This study aims to evaluate the feasibility and safety of DS-MCE with a novel way for complete examination in UGI tract and small bowel, compared with EGD.
Magnetically controlled capsule endoscopy (MCE) has been widely used in clinical practice for upper gastrointestinal (UGI) tract and Small Bowel. However, the complete visualization of UGI tract still present challenges due to rapid transit through esophagus and duodenum, although technical improvements of MCE are helpful.
Detachable String MCE (DS-MCE) can control the movement of MCE through the string and MCE can start next examination after string detachment, which was proved to be an effective and safe method for complete viewing of the esophagus and stomach. In order to improve the duodenum visualization, endoscopist separate MCE from the string after finishing UGI examination so that can inspect the esophagus, stomach and duodenum under the string and magnetic field control.
This is a prospective, single-centered, self-controlled pilot study. Subjects with or without digestive symptoms receiving UGI endoscopy will be enrolled to take DS-MCE and conventional esophagogastroduodenoscopy (EGD) within 48h successively.

| DS-MCE | Device | The subjects swallowed the MCE to investigate the esophagus repeatedly by pulling up or down the string. After completion of the esophageal examination, MCE reached the stomach and was lifted away from the posterior wall, rotated if necessary and advanced to the fundus and cardiac regions, and then to the gastric body, angulus, antrum and pylorus. After finishing the stomach examination, the capsule would enter the duodenum due to peristalsis when the pylorus opened. Then DS-MCE tried to inspect the duodenum repeatedly under the string and magnetic field control, including view of major papilla in the descending part of duodenum and retrograde view of pylorus in duodenal bulb with a "360-degree automatic scanning" mode. After completion of the duodenum examination, the capsule started to view the small bowel. |

The presence of any adverse events during DS-MCE procedure will be recorded.
| up to 2 weeks |
| Detection rate of Z-line, duodenal papilla and pyloric retrograde view | The detection means that at least one image of anatomical structure was obtained. | up to 2 weeks |
| Circumferential visualization of the Z-line and duodenal papilla | It is defined by quadrants as follows: less than 2 quadrants (< 50%) observed; at least 2 quadrants (50%-75%) observed; at least 3 quadrants (>75%) observed; and entire structure (100%) observed. | up to 2 weeks |
| Cleansing level of Z-line and duodenal papilla area | The effect of bubbles/saliva on the appearance of the Z line or duodenal papilla area was both scored as follows: 0=no interference by bubbles/saliva;1=minor interference of bubbles/saliva; 2=major interference of bubbles/saliva. | up to 2 weeks |
| Visualization level of stomach | Visualization level of gastric primary anatomic landmarks: cardia, fundus, body, angulus, antrum and pylorus. (good, >75% of mucosa was observed; moderate, 50% to 75% was observed; poor, <50% of the gastric mucosa was observed) | up to 2 weeks |
| Examination time of esophagus, stomach, duodenum and small bowel | Record the time taken to finish examination in different digestive part. | up to 2 weeks |
| Pyloric transit time | Record the time from completion of the gastric examination to the capsule entering the duodenum. | up to 2 weeks |
| Discomfort scores associated with DS-MCE | Discomfort caused by the string, swallowing the DS-MCE, pulling the capsule up or down, and pulling the string out were on a scale from 0 to 3 (0=none;1=mild/minimal; 2=moderate; and 3=severe/very difficult) according to the Ramirez system. Overall discomfort was scored on a scale of 0 to 10 (0=no discomfort; 10=the overall discomfort of EGD) according to our previous system. | up to 2 weeks |
