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

July 16, 2012 updated by: Yanqing Li, Shandong University

Comparison of Confocal Laser Endomicroscopy With Standard Endoscopy for the Detection and Evaluation of Gastric Intestinal Metaplasia in a High Risk Population: A Randomized Controlled Trial

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.

Detailed Description

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.
