Abstract：

:Digestive endoscopy is currently the main diagnostic procedure for investigation of the digestive tract whenever a digestive disease is suspected. From 1970 to 1985, digestive endoscopy was performed with endoscopes equipped with fiberoptic bundles, whereas the last decade was marked by the development of electronic endoscopes, characterized by the presence of a CCD (charge coupled device) at the tip of the endoscope. Thus the physician looks at a TV screen to control the procedure and examine in detail the gut wall. Endoscopes examine the foregut until the duodenum and the hindgut, up to the three last intestinal loops. When the endoscopic workstation comprises a computer, it is possible to acquire electronic images during the endoscopy and use these images as support of the information about the results of the procedure. These numeric images can then be stored in databases containing text attached to them. Starting with these images, one may expect many developments in the near future that will change the management of the patient with digestive diseases. Physicians will become able to exchange images and text related to one patient or one procedure, although they are equipped with different workstations. Therefore, it is obvious that the information exchanged must be written in a standard format that makes it understandable by all systems. The European Society of Gastrointestinal Endoscopy is a scientific society that groups most of the gastroenterologists in Europe. This society has initiated a research program to develop standards for the exchange of images and text. The Gastrointestinal Endoscopy Applications for Standards in Telecommunication, Education, and Research (GASTER) project intends to implement a multimedia database of endoscopic images based on a standard format of images and a standard terminology for descriptive terms. These standards must be validated by use in different endoscopy units. The database will collect images from these centers that will be linked to the coordinating center through a network based on an integrated services digital network (fast electronic connection). This database will then be used for the development of computer applications. The output of the GASTER project will bring advances at three levels: (1) The physicians will be able to exchange images about the procedures their patients have undergone and will thus obtain more complete information, improving quality of care. They will also benefit from help-to-decision applications based on validated reference images from the database. (2) At the patient level, the quality of care will be improved through a better dissemination of information between the physicians in charge of the patient, thus there is better follow-up of the patient and a decrease in redundant examinations. (3) At the level of national health care systems, the benefit will be a decrease in cost of care due to a better follow-up of the patients, a decrease in redundant examinations, and a faster decision made to treat the patient. The possibility of consulting a database of a scientifically validated images used as reference material will also improve quality control in digestive endoscopy.
