Miniature endoscopes that can be introduced into the bile duct through the duodenoscope during endoscopic retrograde cholangiopancreatography were developed to allow nonsurgical management of difficult biliary stones. The direct visualization…
Endoscopic retrograde cholangiopancreatography allows intervention for a variety of diseases of the biliary tract. Cannulation of the bile duct is the prerequisite step for biliary intervention. Although obtaining biliary access…
Infection of the biliary tract, or cholangitis, is a potentially life-threatening condition. Bile duct stones are the most common cause of biliary obstruction predisposing to cholangitis. The key components in…
Advances in biliary imaging have improved making accurate diagnoses of the presence and causes of biliary obstruction. Abdominal ultrasound is a useful screening tool because it is highly specific for…
Jacques Van Dam, MD, PhD, Editor This time, something a little bit different. More often than not, Gastrointestinal Endoscopy Clinics of North America focuses on a particular instrument or procedure….
Charles J. Lightdale, MD, Consulting Editor The biliary tract is subject to a multiplicity of ills spanning an incidence of common to rare. Imaging of the biliary system with ultrasound,…
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…
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…
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…
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…
