Magnetically Controlled Capsule Endoscopy in Visualization of the UGI and Small Intestine

Feasibility of the Magnetically Controlled Capsule Endoscopy in One Time Visualization of the Upper Gastrointestinal Tract and Small Intestine

In this study, we retrospectively analyzed the videos of combined upper digestive tract and small intestine examination under MCE, so as to clarify the feasibility and diagnostic efficacy of MCE in one-time examination of the upper gastrointestinal and small intestinal mucosa.

Magnetically controlled capsule endoscopy (MCE), with equally favorable diagnostic accuracy as conventional endoscopy, has become a painless noninvasive diagnostic modality in clinical practice. The more than 8 hours battery life of the MCE enables a further examination of the small bowel. In addition, it has been demonstrated that magnetic steering of capsule endoscopy improves the completion rate of small bowel examination by facilitating passage of the capsule through the pylorus, which further supported MCE as a practical modality for examination of both the stomach and small bowel. In this study, we retrospectively analyzed the videos of combined upper digestive tract and small intestine examination under MCE, so as to clarify the feasibility and diagnostic efficacy of MCE in one-time examination of the upper gastrointestinal and small intestinal mucosa.
