About this study
Official title: Feasibility of Non-contact Magnetically-controlled Capsule Endoscopy During COVID-19 Pandemic: a Prospective, Open-label, Pilot, Randomized Trial
In December 2019, an outbreak of pneumonia associated with a novel coronavirus named as severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) was reported in Wuhan city, China, and spread exponentially throughout China and other countries in the following weeks.
It is recommended that elective endoscopies should be deferred during the COVID-19 outbreak for the potential transmission between patients and medical staff in the statements of Asian Pacific Society for Digestive Endoscopy (APSDE-COVID statements). Therefore, exploring an alternative for patients with the requirements of endoscopy during the outbreak is of great importance.

Herein,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.
This 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.
Read the detailed description
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.
The 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).
The 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.

What participants receive. In a randomised study each person is assigned to one group by chance.
non-contact magnetically-controlled capsule endoscopyDevice
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.
| Study group | Role | What they receive |
|---|---|---|
| Non-contact MCE examination | Experimental | 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. Receives: Device: non-contact magnetically-controlled capsule endoscopy |
| MCE examination | Active comparator | 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. Receives: Device: non-contact magnetically-controlled capsule endoscopy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Complete Observation
The number of participants with complete observation. Complete observation of the mucosa means over 90% of the mucosa observed in gastric cardia, fundus, body, angulus, antrum and pylorus.
Measured: During the procedure
Secondary outcomes (4)
Maneuverability Score
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.
Measured: During the procedure
Gastric Examination Time(GET)
GET was defined as the time taken for the endoscopist to complete the gastric examination to his or her satisfaction
Measured: During the procedure
the Comfort and Acceptability of Patients
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.
Measured: After the procedure(within 5 days)
The Total Number of Patients Who Who Had a Diagnosis of Positive Findings
It was calculated using the following formula: number of patients with positive findings divided by the total number of patients that underwent examination.
Measured: after the procedure(within 5 days)

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 4 Jan 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Complete Observation (time frame: During the procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04389333, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jan 2022.
