Confocal Laser Endomicroscopy for the Detection of Gastric Intestinal Metaplasia: a Randomized Controlled Trial

2014-08-27 03:17:33 | BioPortfolio


The purpose of this study is to assess whether confocal laser endomicroscopy can reduce the biopsy number needed per patient for the detection of gastric intestinal metaplasia without the loss of corresponding diagnostic yield.


Gastric intestinal metaplasia is a well-known premalignant lesions for intestinal type gastric cancer. However, present guidelines such as the updated Sydney System require multiple biopsies whereas reveal an unsatisfactory yield considering the detection and surveillance of these lesions. Confocal laser endomicroscopy is a newly developed endoscopic device that enables microscopic view of the digestive tract. Previous study has showed high sensitivity and specificity for in vivo diagnosis of gastric intestinal metaplasia using confocal laser endomicroscopy. This study aims to assess the real number of biopsies that can be reduced for the detection of gastric intestinal metaplasia using confocal laser endomicroscopy.

Medical and Biotech [MESH] Definitions

Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument along either natural body pathways such as the digestive tract, or through keyhole incisions to examine the interior parts of the body. With advances in imaging, endoscope, and miniaturization of endosurgical equipment, surgery can be performed during endoscopy.

Visualization of the heart structure and cardiac blood flow for diagnostic evaluation or to guide cardiac procedures via techniques including ENDOSCOPY (cardiac endoscopy, sometimes refered to as cardioscopy), RADIONUCLIDE IMAGING; MAGNETIC RESONANCE IMAGING; TOMOGRAPHY; or ULTRASONOGRAPHY.

A condition caused by the lack of intestinal PERISTALSIS or INTESTINAL MOTILITY without any mechanical obstruction. This interference of the flow of INTESTINAL CONTENTS often leads to INTESTINAL OBSTRUCTION. Ileus may be classified into postoperative, inflammatory, metabolic, neurogenic, and drug-induced.

Dilatation of the intestinal lymphatic system usually caused by an obstruction in the intestinal wall. It may be congenital or acquired and is characterized by DIARRHEA; HYPOPROTEINEMIA; peripheral and/or abdominal EDEMA; and PROTEIN-LOSING ENTEROPATHIES.

A highly basic, 28 amino acid neuropeptide released from intestinal mucosa. It has a wide range of biological actions affecting the cardiovascular, gastrointestinal, and respiratory systems and is neuroprotective. It binds special receptors (RECEPTORS, VASOACTIVE INTESTINAL PEPTIDE).
