Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to determine the accuracy of detachable string magnetically controlled capsule endoscopy(DS-MCE) as a follow-up method for patients with previous esophageal diseases.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Esophagogastroduodenoscopy (EGD) is recognized as the gold standard for detection and follow-up of esophageal diseases,allowing for direct mucosal visualization and therapeutic intervention. EGD is however an invasive procedure and there is potential for procedure-related complications, such as perforation and bleeding.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.

The ds-MCE system consists of two parts: the magnetically controlled capsule endoscopy (MCE) system and a transparent latex sleeve with a hollow string. The magnetically controlled capsule endoscopy (MCE) system (Ankon Technologies, Shanghai, China) detects focal lesions in the stomach with comparable accuracy with conventional EGD. One end of the hollow string is a transparent thin latex sleeve that can be wrapped on the surface of the capsule, and the other end of the string is connected to the syringe. The capsule, which is partially enclosed within the sleeve, can be actively moved in the esophagus through the control of string. In this case, investigator can examine the entire esophageal mucosa several times under real time views. The capsule then could be detached from the string system through injecting air into the hollow string with the syringe after completing the examination of esophagus. The pilot study of ds-MCE confirmed it was a feasible, safe and well-tolerated method for completely viewing esophagus and stomach, without the need for sedation. Besides, the 8-10h battery life of the ds-MCE enables complete examination of the small bowel, which provides the possibility for screening pathological changes in the entire gastrointestinal tract.

This study is a prospective, multi-centered, diagnostic accuracy study. The primary outcome is the diagnostic accuracy of ds-MCE in identifying esophageal diseases. Second outcomes include the visualization and cleanliness of Z-line, safety and patient satisfaction of DS-MCE.

Study Groups

ds-MCE and EGD

All the enrolled participants will undergo the examination of detachable string magnetically controlled capsule endoscopy (ds-MCE) first, followed by EGD within 48 hours.

Group Type EXPERIMENTAL

ds-MCE and EGD

Intervention Type DIAGNOSTIC_TEST

Procedure of ds-MCE: The ds-MCE system mainly consists of two parts: the NaviCam magnetic capsule endoscopy guidance system and the detachable string part. The capsule, which is partially enclosed within the sleeve, can be actively moved in the esophagus through the control of string. Investigator can examine the entire esophagus several times under real time views. The capsule then could be detached from the string system through injecting air into the hollow string with the syringe after completing the examination of esophagus. Then, the examination of stomach under magnetic control and small bowel under the natural action of peristalsis follows.

Procedure of EGD: The EGD will be performed using conventional upper gastrointestinal video endoscopy, according to the standard procedure at individual centers. EGD will be performed within 48 hours after ds-MCE procedure and usually during the same endoscopic session.
