[Perspectives of using radiofrequency surgery in operations on the major duodenal papilla]

The article presents the results of an experimental study of the possibility of using radiofrequency surgery for performing papillosphincterotomy. A generator of radiowaves of a high frequency range was used for the generation of the electromagnetic field, which when acting upon the living tissues makes a cut and destruction of the tissue. The experiment was made in 20 dogs divided into two groups for acute and chronic experiments. In the group of chronic experiments the dogs were exterminated on the 7, 14, 21 and 35th days after operations. The area of the influence in all the periods of the experiment was investigated histologically. Significant advantages of the given method as compared with the traditional ones were revealed.
