To date, multiple CE systems from different companies are available. Nevertheless, currently only the Given M2A video capsule system (Given Imaging Ltd., Yoqneam, Israel) and the Olympus Endocapsule (Olympus, Tokyo, Japan) are FDA and CE approved. Capsule systems are available for examination of the esophagus, small bowel and colon. While suspected small bowel stenosis is a contraindication for performing CE a patency capsule (Agile capsule, Given Imaging) was developed for these patients. This capsule is a self-dissolving capsule with the same size as the conventional CE and contains a radiofrequency identification tag that allows it to be detected by a scanning device placed on the abdominal wall. In addition, it has a radiopaque coating that permits its location within the bowel using fluoroscopy. When its passage is blocked by a stenosis or tumor, the patency capsule dissolves within 40-80 h after ingestion.Although the capsule is easily ingested and swallowed by most individuals, patients with severe dysphagia, large Zenker's diverticulum, pill phobia, significant gastropareses, and small children may have problems ingesting the device. For these situations, a capsule-loading device (AdvanCE, US Endoscopy, Mentor, Ohio, USA) is available to directly deliver the capsule into the stomach or duodenum. The disposable device is a 2.5-mm singlesheathed device which is first preloaded through the working channel of a standard endoscope. The activated

AbstractSince the advent of capsule endoscopy (CE) more than one decade has passed. During this time, extensive efforts have been made to proof the relevance of CE for diagnosis of various disease entities within the esophagus, small bowel, and colon. To date, the most common indications for CE are obscure gastrointestinal bleeding, Crohn's disease, polyposis syndromes and evaluation of patients with complicated celiac disease. In this review we will focus on the current clinical applications of CE for imaging of the esophagus, small bowel and colon and will additionally give an outlook on future concepts and developments of CE.
