FORMATION OF THE COMPRESSION DOUBLE-FLAP CHOLECYSTOENTEROSTOMY USING A TITANIUM NICKELIDE DEVICE

The paper presents the results of an experimental study on 20 mongrel rabbits of both sexes, in whom two-valve cholecystoenteroanastomosis was formed with a compression device made of titanium nickelide with shape memory. This device allows formation of anti-reflux anastomosis between the biliary tract and the jejunum. The technique is simple and not time-expensive. The compression device after the operation is rejected for 7-9 days and leaves the gastrointestinal tract naturally. Compression cholecystoenteroanastomosis formed by the developed technology has the high level of mechanical strength. At the 1st-3rd-7th day, it amounted to 127.5-96.25- 150 mm Hg. This level exceeds significantly the tightness threshold. Then, at 14th-90th days, the tightness of the anastomosis increases up to 216.25-260 mm Hg. The X-ray analysis has proved that the valve is functionally active.
