[Improvement of visualization--a real way to increase the effectiveness of endoscopy in continuing gastroduodenal bleedings].

: A special device--"a low temperature washer"--had been developed and introduced into practice for the improvement of a visual picture in an endoscopic examination of bleeding gastroduodenal ulcers. An estimation of the results of using the device in emergency endoscopic examinations was made in an analysis of results of the diagnosing and treatment of 246 patients (1999-2003). This device allowed almost 100% elevation of the diagnostic and 2.5 times higher medical effectiveness of emergency endoscopy, and 2.5 times less amount of operations performed at highest bleeding.
