| Summary: | The work is devoted to the problem of reducing intra- and postoperative complications in patients with surgical gastrointestinal tract pathology. The aim of the study is to comprehensively investigate electrosurgical and ultrasound dissection and coagulation features to prevent intra- and postoperative complications, improve the results of treatment of patients with surgical gastrointestinal tract pathology. The study included experimental and clinical parts. The use of ultrasound scanning in the main group of patients revealed significant advantages of this method compared to MES. This device allowed not only to carry out the dissection of the gastrointestinal tract organs, but also to mobilize them, thereby simplifying and speeding up the operation. Intersection of vessels of both omenta, small and large intestines mesentery vessels was carried out with alternating regimes of coagulation and cutting, while ligating only large blood vessels. The study showed that thanks to the use of ultrasound scanning it was possible to reduce the number of postoperative complications from 16.2% to 6.7%, postoperative mortality decreased from 6.11% to 1.55%, and postoperative bed-day decreased from an average of 17.5+ 3.75 to 12.5 + 2.58, which in the complex allowed to improve the parameters of treatment and rehabilitation of patients.
