Magnetic Endoscope Imaging: A New Technique for Localizing Colonic Lesions

Abstract

MEI is a reliable and accurate method for determining the anatomical position of the endoscope tip during colonoscopy. When it becomes commercially available, we believe the use of MEI will avoid the need for unnecessary barium enemas for localization of lesions prior to definitive surgery.

Locating polyps by endoscopy with or without videolaparoscopy, radioguided occult colonic lesion identification or magnetic endoscopic imaging: the way forward to complete polyp removal

“…The system automatically produces an antero-posterior view of the scope within the abdomen but can also give a simultaneous lateral view. An additional sensor coil is contained within a plastic button and can be attached to the endoscopy assistant's hand when applying abdominal compression, so that the hand can be seen in relation to the scope [6].…”

A preliminary prospective study of the usefulness of a magnetic endoscope locating device during colonoscopy

“…Shah et al have conducted several studies to investigate the utility of the EPDU during colonoscopy [11][12][13][14][15][16]. In one study, a single trainee was allowed to view the magnetic imager display for some examinations but not for others.…”

“…Although magnetic endoscope imaging of the colonoscope has been studied to some extent in Europe and has been shown to be a useful aid during colonoscopy, its use in the United States has been limited [10][11][12][13][14][15][16][17]. The technology, as incorporated into the Endoscope Position Detecting Unit (EPDU) (Olympus Optical, Tokyo, Japan), was first introduced in prototypical form in 1993.…”

Determining scope position during colonoscopy without use of ionizing radiation or magnetic imaging: the enhanced mapping ability of the NeoGuide Endoscopy System

“…Fluoroscopy and magnetic endoscopic imaging systems are able to provide physicians with information regarding scope shape. However, they are limited by cost, cumbersome hardware, and the risk to both patient and staff of ionizing radiation [9][10][11][12][13][14][15][16][17][18]. In this study we evaluated the in vitro mapping capabilities of the NeoGuide Endoscopy System in terms of colonic looping, insertion depth, tip position, and tip angle formation.…”
