One of the challenges encountered during surgical operations connected with a part of proctologic pathologies (pararectal fistulas, anal sphincter insufficiency, rectocele etc.) is differentiation of muscles raising the anal sphincter or anus among tissues. E.g. selection of surgical operation for pararectal fistulas depends on the location of the way of fistula in relation to the anal sphyncter. Sometimes, resection of a major part of sphincter may result in more tiring disease – formation of anal incontinence. During surgical correction of anal sphycter insufficiency, suturing of the edges of the sphycter, and of the diverged groups of muscles raising anus during rectocele operations ensures success of the operation. However, in a number of cases, development of healing tissue on the background of long-term chronic inflammatory process or underwent surgical operations visually or palpatively complicates finding of muscles. To facilitate the settlement of the problem, we offer the use of electromyography (EMG). EMG was performed by using concentrated needle-tip electrodes. The electrode was displayed by intensification of echosignals on the monitor on reaching the muscular tissue by gradual location through passing to deeper layers beginning with controlled area. Quantitative assessment of electric activity of muscles was carried out on the electromyography and muscular density is determined. EMG is a method of examination based on the registration of electric biopotential formed in muscles and showing functions condition of muscles. By using EMG (32 operation) it is possible to determined the availability of muscular tissue in the tissue on the probe passing through pararectal fistula, to determine the volume of muscular bulk, which allows to differentiate intrasphyncter fistulas from extra and or transphyncter fistulas, as well as to determined the extent of influence of cutting the fistula way in the latter on the contractibility of sphincter. EMG was also used for suturing of the edges of the sphyncter (5 operations), and finding of the diverged muscle bulks raising anus during surgical correction of anal sphincter insufficiency in rectocele operations (10 operations). Thus, EMG facilitates finding of muscle structures in the course of proctologic operations and ensures success of operations.
