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

The purpose of the study is to determine the safety and feasibility of the new technique,detachable string magnetically controlled capsule endoscopy(DS-MCE)for evaluating gastric and esophagus diseases.

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.

Inclusion Criteria:

• outpatients who have esophagus symptoms.

Exclusion Criteria:

• known or suspected complex history of gastrointestinal obstruction, stenosis or fistula.
• dysphagia or delayed gastric emptying.
• known or suspected possibility of active bleeding of digestive tract.
• a history of abdominal operation.
• pacemaker implantation and gastrointestinal pacemaker users.
• patients who are allergic to simethicone or pronase.
• pregnant women,mental patients.
• other circumstances that doctors consider inappropriate for the study.
