[FORMATION OF BILIODIGESTIVE AND INTERINTESTINAL ANASTOMOSES IN ENVIRONMENT OF BILIARY PERITONITIS, USING A HIGH FREQUENCY ELECTRIC WELDING IN EXPERIMENT].

ABSTRACT

In experiment on 20 rabbits a diffuse biliary peritonitis was simulated, using intraabdominal injection of a laboratory culture of E. coli suspension and a medicinal bile. In 24 h on background of peritonitis on excluded loop of a small bowel in accordance to method of Roux, using a high frequency electric welding with the help of apparatus Patonmed EKB3-300 a one-layered everting cholecystoenteroanastomosis and enteroenteroanastomosis was formated. In a 6 mo postoperatively a connection line was not revealed from outside or from inside, the signs of stenosis were absent. In environment of a diffuse biliary peritonitis a welding technologies have permitted to form a hermetic and competent biliodigestive and interintestinal anastomoses, the processes of a welding suture regeneration postoperatively have a typical course. Using a high frequency-electric welding it is possible to perform a one-staged reconstructive interventions in environment of a pronounced inflammation of tissues due to subsequent precise conjunction of mucosal sheets of connected organs, preventing the anastomotic stricture formation.
