Detachable String Magnetically Controlled Capsule Endoscopy for Completely Viewing of Esophagus and Stomach
A Novel Detachable String Magnetically Controlled Capsule Endoscopy (DS-MCE) for Viewing Esophagus and Stomach
Study Overview
Detailed Description
Esophageal capsule endoscopy(ECE)provides a novel noninvasive approach to visualize the esophagus.The main drawback for the use of ECE is its unreliable transit time which often renders an inadequate visualization of the esophagus.Thus investigators have developed the detachable string magnetically controlled capsule endoscopy(DS-MCE) which can control the movement of the capsule through the string.
This study is a prospective, single-centered, self-controlled pilot study.Outpatients who have esophagus symptoms will take conventional endoscopy examination and DS-MCE successively.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: DS-MCE
outpatients who have esophagus symptoms will take DS-MCE and conventional endoscopy examination examination successively.
|
During the DS-MCE examination,the capsule is allowed to travel down into gastric cardia,from where the string is slowly pulled to allow the capsule to view the esophagus retrogradely.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Successful Separation of Capsule and String, and Complete Viewing of Esophagus and Stomach
Time Frame: up to 2 weeks
|
evaluate the feasibility of the novel DS-MCE examination.
The successful separation of the capsule and string was evaluated by the capsule entering the stomach and and the string being pulled out.Complete viewing of esophagus and stomach was evaluated by completing the procedure from the capsule being swallowed, the esophagus observed retrograde, to the string being pulled out after separating from the capsule.This primary outcome indicated how many participatns completed the DS-MCE examination successfully.

up to 2 weeks

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of DS-MCE Associated Adverse Events
Time Frame: up to 2 weeks
|
evaluate the safety of DS-MCE.Record any adverse event during the procedure and after the procedure.Patients will be followed up by telephone to inquire about the symptoms of abdominal distention, abdominal pain,vomiting and other discomfort.
Follow up to the end of the capsule expulsion.
|
up to 2 weeks
|
Duration of Time Capsule is Within the Esophagus
Time Frame: up to 2 weeks
|
time from the capsule swallowed to the capsule entering the gastric cardia to examine the stomach
|
up to 2 weeks
|
Z-line Visualization
Time Frame: up to 2 weeks
|
Z-line represents the normal esophagogastric junction where the squamous mucosa of the esophagus and columnar mucosa of the stomach meet.We can devide the Z-line into four quadrants under capsule endoscopy.
Observing all the four quadrants is considered to be a complete observation of Z-line.
In this study,the number of participants with at least two quadrants of Z-line visualized was used to evaluate the Z-line visulization.
|
up to 2 weeks
|
Quality Score of Z-line Images
Time Frame: up to 2 weeks
|
grade (mild, moderate,and severe) of air-bubble and saliva interference on the Z-line view(0, no intraluminal gas bubble; 1, a few gas bubbles, no limitation of interpretation; 2, an increased amount of intraluminal foam/gas bubbles, moderate limitation of visibility; 3, an amount of foam/gas bubbles)
|
up to 2 weeks
|
Degree of Comfort
Time Frame: up to 2 weeks
|
evaluate patient's degree of comfort throughout the procedure.Patients will be asked to fill in a questionnaire to give scores about degree of comfort throughout the procedure.Overall discomfort was scored on a scale of 0 to 10 (0, no discomfort; 10, the overall discomfort of EGD).
|
up to 2 weeks
