The aim of the work: to improve the results of surgical intervention and reduce the number of post-gastroresection complications by conducting experimental and clinical studies, developing, testing and introducing the known and improving options for tubular resection of the stomach (TRS) in the treatment of patients with chronic and complicated gastric resection with various options for restoring the continuity of the gastrointestinal tract.
Materials and Methods. Blood supply and innervation of the gastric stump (GS) were studied angiographically in 48 adult dogs and 20 organocomplexes of human corpses by the method of preparation after organ-saving sphenotubular resection of the stomach (STRS).
Results and Discussion. In 20 dogs, the state of vascular-neurocellular microcomplexes (VNM) of the walls of the GS was studied at different times (1–2 weeks – 3–5 years) after STRS 1/3 and 2/3. It was established that GS after STRS has reliable blood supply and innervation, regardless of the level of resection and means of restoring the continuity of the gastrointestinal tract (GIT). The found atrophic and partially dystrophic changes in some of the neurons and nerve cords in the GIT against the background of compensatory vascular changes, which are most pronounced in the final part of the GS after STRS 2/3, regardless of the means of restoration of the gastrointestinal tract. Successful implementation of the results of the study was performed in 52 patients with chronic and complicated gastrointestinal ulcers who underwent STRS 1/3 and 2/3.
