Red-Flag Technologies in Gastric Neoplasia
Given its morbidity and mortality, the early detection and diagnosis of gastric cancer is an area of intense research focus. This article reviews the emerging use of enhanced endoscopic imaging…
Endomicroscopy and Endocytoscopy in IBD
Two types of endomicroscopy systems exist. One is integrated into a standard, high-resolution endoscope and one is probe-based, capable of passage through the working channel of a standard endoscope. Endocytoscopy…
Optical Molecular Imaging in the Gastrointestinal Tract
Recent developments in optical molecular imaging allow for real-time identification of morphologic and biochemical changes in tissue associated with gastrointestinal neoplasia. This review summarizes widefield and high-resolution imaging modalities in…
Surveillance in Inflammatory Bowel Disease
Patients with long-standing inflammatory bowel disease (IBD) have an increased risk of developing colorectal cancer. Performing periodic dysplasia screening and surveillance may diminish this risk. To date, chromoendoscopy is the…
Colonic Polyps
Colorectal cancer represents a major cause of mortality in Western countries, and population-based colonoscopy screening is supported by official guidelines. A significant determinant of the cost of colonoscopy screening/surveillance is…
The New View of Colon Cancer Screening
Many different techniques for colon cancer screening are available. The fecal immunochemical test is best for fecal-based screening, although the DNA investigation may be more specific when further developed. Computed…
Advanced Techniques for Endoscopic Biliary Imaging
Cholangioscopy, endosonography, and confocal microscopy represent important technologies that expand biliary imaging beyond a level previously realized by noninvasive modalities (ultrasonography, computed tomography, and magnetic resonance cholangiopancreatography) and endoscopic retrograde…
Advanced EUS Imaging for Early Detection of Pancreatic Cancer
Endoscopic ultrasound (EUS)-fine needle aspiration remains the gold standard for diagnosing pancreatic malignancy. However, in a subset of patients, limitations remain in regards to image quality and diagnostic yield of…
Endomicroscopy in Barrett’s Esophagus
Barrett’s esophagus has been a focus of confocal laser endomicroscopy (CLE) research. There are two CLE systems available, one probe-based and the other with a microscope embedded in the tip…
Optical Coherence Tomography in Barrett’s Esophagus
The incidence of Barrett’s-related adenocarcinoma of the esophagus continues to increase at an alarming rate. Studies to date show great promise for optical coherence tomography (OCT) in screening, surveillance, and…
