[FORMATION OF BILIODIGESTIVE ANASTOMOSES BY THE METHOD OF HIGH-FREQUENCY ELECTRIC WELDING].

The aim of the study was to develop a new method of formation of biliodigestive anastomoses, which would make it possible to form anastomoses both on unchanged bile ducts and in conditions of their inflammation. An experimental study was carried out on 50 rabbits of the "Chinshila" breed, which formed biliodigestive and interintestinal anastomoses by the method of high-frequency (HF) electric welding using the "Patonmed EKVZ-300" coagulator. Anastomoses were formed both on non-inflamed tissues and under conditions of biliary peritonitis.

[[Estimation of bilio-oigestive and interintestinal anastomoses, formed in accordance to method of a high-frequency electric welding of tissues, in experiment].].

In the experiment on 50 rabbits cholecysto-entero and entero-entero anastomoses were formed on intestinal Roux loop. In 35 animals (the main group) a single layer evert- ing anastomoses by using high frequence (HF) electric welding method were formed, in 15 (the comparison group) single row suture anastomoses has been done. The anas- tomosis sufficiency were performed by using hydropressure, pneumopressure meth- ods and breakload test.

[PRINCIPLES OF THE HEPATICO-JEJUNOANASTOMOSIS FORMATION, USING METHOD OF THE SOFT-TISSUES HF-ELECTRIC WELDING IN CLINICAL PRACTICE].

Hepatico-jejunoanastomosis (HJA) was formed in accordance to the high-frequency electric welding method: in 14 patients – for the main bile outflow disorders, in 8 of them – as a consequence of the periampullar zone malignances, in 6 – stricture of a common hepatic duct, HJA earlier formatted, purulent cholangitis, iatrogenic damage of biliary ducts. In all the patients the welded averting one-layered termino-lateral or latero-lateral HJA were formatted. The welded anastomoses have appeared hermetic, sufficiently hard, immediately after the formation and further.
