Molecular Imaging in Gastrointestinal Endoscopy

Ethical aspect in Gastrointestinal Endoscopy in Iran

    Abstract   Background: Gastroenterologists are required to obtain consent before undertaking   any endoscopic examination. Published data indicate that in practice there are many deficiencies in this process. The aim of this survey was to determine the quality of information given to patients before the endoscopic procedures in Iran .   Methods: A structured questionnaire about patient's in...

Stents in Gastrointestinal Endoscopy

Advanced endoscopy can be used to insert stents (hollow tubes) into various sites of the gastrointestinal tract and this has proved to be a major therapeutic advance. Stents can hold open strictured areas in the oesophagus, the biliary tree, the colon and the gastroduodenal region. Stents are usually positioned in order to overcome stricturing associated with cancerous tumours. They are used as...

Novel Imaging Techniques in Gastrointestinal Endoscopy in the Upper Gastrointestinal Tract

Endoscopic Molecular Imaging in Gastrointestinal Oncology

Gastrointestinal (GI) endoscopy has been widely used for detection, differentiation and staging for neoplasia in the digestive tract, and has made great progress during the last decade (Sivak, 2006). Diagnostic accuracy can be enhanced by better training, more efficient techniques, and the development of new image-processing technologies (Cotton et al., 2006; Tajiri, 2007); however, diagnosis u...

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 preclinical and clinical evaluation for the detection of colorectal cancer and esophageal cancer. Widefield techniques discussed include high-def...
