About this study
Official title: New Method: Can Magnetic Steering Enhance Capsule Gastroscopy Gastric Emptying?
The research continuously enrolled 100 patients undergone MCCG between May to December 2017 as the intervention group with magnetic steering of capsule in the pylorus and duodenum, and randomly selected 100 patients before May 2017 from the database as the control group with passive movement of the capsule. The difference of the pyloric transit time (PTT) and duodenal papilla detection rate (DPDR) between the two groups were compared, and related factors were also investigated.
Read the detailed description
Background and Aims: Capsule endoscopy is a valuable tool in the diagnosis of small bowel disease. However, the incompletion of small bowel examination may reduce the diagnostic accuracy, which mainly caused by delayed capsule gastric emptying. Thus the aim of this study was to validate the effect of magnetic steering on enhancing gastric emptying and mucosal visualization within duodenum during magnetically controlled capsule gastroscopy (MCCG) examination.
Methods: As a historical prospective cohort study, the research continuously enrolled 100 patients undergone MCCG between May to December 2017 as the intervention group with magnetic steering of capsule in the pylorus and duodenum, and randomly selected 100 patients before May 2017 from the database as the control group with passive movement of the capsule. The difference of the pyloric transit time (PTT) and duodenal papilla detection rate (DPDR) between the two groups were compared, and related factors were also investigated.

| Study group | Role | What they receive |
|---|---|---|
| control | No intervention | The patients swallowed the capsule with water in the lying position.After finishing the stomach examination, the operation of the capsule is adjusted to "small bowel mode" without magnetic control. Capsule entered the duodenum under physiological peristalsis. The position of the capsule was established using a real-time viewer. If the capsule failed to enter the duodenum after one hour, domperidone (10 mg) was orally administered. |
| magnetic steering | Experimental | After finishing the stomach examination as the control protocol, the capsule was lifted with the magnetic control, then rotating the capsule until the camera end oriented toward the pylorus . Next, the endoscopist could drag the capsule close to the pylorus with the guidance magnet robot, waiting for the open of pylorus. Once the pylorus opened, the capsule could enter the duodenum with gastric peristalsis. After reaching the duodenal bulb, capsule was held to the maximum position of "Z", then the capsule would scan the duodenal bulb automatically with the mode "360° automatic scanning".

Questions about this trial
What is this clinical trial studying?
A study testing magnetic steering in people with Capsule Endoscopy and Gastric Emptying, run by Zhuan Liao at 1 site in China.
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 4 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: status not confirmed, as of the sponsor's last update on 22 Feb 2018. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
PTT (time frame: 3 month). 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 NCT03441945, which also lists 6 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.
