Therefore, exploring an alternative for patients with the requirements of endoscopy during the outbreak is of great importance.\n\nHerein,the investigators developed an novel non-contact magnetically-controlled capsule endoscopy (Nc-MCE) system (Figure 1) adds a remote control workstation and a audio-visual exchange system to the original well-established MCE system.\n\nThis study was a open-label, prospective, randomized controlled study approved by the institutional review board of Shanghai Changhai Hospital. It was designed to evaluate the diagnostic utility, safety, feasibility and patients acceptability of Nc-MCE in patients with an indication of endoscopy, and comparing it with the result of MCE.', 'detailedDescription': 'The nc-MCE system added a remote control workstation and an audio-visual exchange system to the original well-establish MCE system.Conventional protective measures could be adopted to endoscopist. Although the endoscopist and the patient are in different rooms, the endoscopist was able to see the patient and communicate with him or her through the audio-visual exchange system all the time. In order to simplify the examination procedure, the data recorder was putted on the examination bed. The patient lay down after swallowing the capsule under the remote guidance of the endoscopist.And the endoscopist of MCE and nc-MCE was the same one with experience of more than 1000 cases of MCCG operation.\n\nThe investigators recruited 40 patients who have related symptom and healthy people mainly from outpatient clinic or hospital health examination center. After fully understanding the procedure of nc-MCE, patients with informed consent were randomly divided into MCE group and nc-MCE group(1:1) by using a stratified block randomization(block size four).\n\nThe basic characteristics of the enrolled patients were prospectively collected. The primary endpoint was the maneuverability score evaluated by endoscopist. And the investigators choose the gastric examination time,the comfort and acceptability of patients, diagnostic yield and completeness of gastric examination as the secondary endpoint. The safety endpoint of nc-MCE was evaluated by the occurrence of adverse events.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\nSigned the informed consents before joining this study\n\nExclusion Criteria:\n\n(1) dysphagia or symptoms of gastric outlet obstruction, suspected or known intestinal stenosis,overt gastrointestinal bleeding,fistulas and strictures; (2)history of upper gastrointestinal surgery or suspected delayed gastric emptying; (3) Patients with poor general condition,asthma or claus trophobia; (4) Implanted metallic devices such as pacemakers,defibrillators, artificial heart valves or joint prostheses; (5) Pregnancy or mentally ill person; (6) currently participating in another clinical study;(7)communication obstacles persons.'}, 'identificationModule': {'nctId': 'NCT04389333', 'briefTitle': 'Feasibility of Non-contact Magnetically-controlled Capsule Endoscopy During COVID-19 Pandemic', 'organization': {'class': 'OTHER', 'fullName': 'Changhai Hospital'}, 'officialTitle': 'Feasibility of Non-contact Magnetically-controlled Capsule Endoscopy During COVID-19 Pandemic: a Prospective, Open-label, Pilot, Randomized Trial', 'orgStudyIdInfo': {'id': 'nc-MCE pilotRCT'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Non-contact MCE examination', 'description': '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.
