METHOD OF DIAGNOSTICS OF POSITION AND PASSABLENESS OF TUBULAR ESOPHAGEAL ENDOPROSTHESIS

FIELD: medicine. ^ SUBSTANCE: after installation of the silicon endoprosthesis or in the course of observation over the patient in 8 hours after food intake transcutaneous from subcostal access in a prone position, using the multifrequency gauge 4V2G in a format of a vectorial lattice with frequency 4.0 MHz in B - mode (ultrasonic equipment - Aspen, "Acuson", USA, the program "ABDOMEN") scan a tubular esophageal endoprosthesis in thoracal and abdominal departments of an esophagus in the form of four linear hyperechogenic parallel signals. Define protector position, measure its length, external and internal diameters. After that in position on the left side, the patient drinks 200 ml of the distilled water through a tube of 5 mm. Liquid passage through a lumen of the endoprosthesis and its intake in a stomach scan from the subcostal access by the multifrequency gauge 4V2G in a format of a vectorial lattice with frequency 4.0 MHz in B - mode. ^ EFFECT: provides creation of a non-invasive way of diagnostics of position and passableness of a tubular esophageal endoprosthesis, reduction of examination time. ^ 3 dwg, 3 ex
