Abstract

Objective. To develop a new method of the anastomoses formation, that would allow to form bilio-digestive and entero-entero anastomoses both on unchanged and inflamed tissues.

Маterials and methods. In experimental on 50 laboratory rabbits the single-layer everting cholecysto-entero and entero-entero anastomoses on the Roux-defunctionalized loop of small intestine was created by the method of a high-frequency electric welding. The welding anastomoses were formed both on non-inflamed tissues and in the setting of biliary peritonitis. Patency, hermeticity, strength, macroscopic and microscopic pictures of the obtained joints were evaluated at different postoperative periods.

Results. All anastomoses, formed by the method of a high-frequency electric welding, were not only patent and hermetic, but also sufficiently strong (40 – 100 mm Hg). The tissues were joined using thermo-adhesion; a coagulation scar was rather narrow, its complete epithelization was accomplished in 3 mo, and a scar maturation completed – in 6 mo.

Conclusion. The method of a high-frequency electric welding permits to form both, bilio-digestive and inter-intestinal, anastomoses of equal reliability in the settings of non-inflamed and inflamed tissues.
