[Future trends in the development of endoscopic studies of digestive tract organs].

Presented in the paper are new promising endoscopic devices for examinations of the digestive tract organs. Special attention is paid to one of the important directions, the development of endoscopes for peroral examinations of hepatic passages, the intraoperation choledochoscopy. In order to improve the diagnostic capabilities of the small intestine endoscopy the development of a long controllable endoscope is advisable. A new trend in endoscopy, the endoscopic microscopy, is noted to be of great research importance. This trend calls for creation of not only new methodologic basis but of new types of endoscopes as well. They should be capable of detecting changes in both structural formations and cell structures.
