Exploring a crucial aspect of geriatric surgery, this article delves into the pathogenesis of acute intestinal obstruction in elderly and senile patients

Pathomorphological changes in the intestine in the development of acute intestinal obstruction depend on the form of the lesion. So, in patients with strangulated intestinal obstruction, the main affected area is considered to be the strangulation area, that is, the place where the main vessels and nerves of the mesentery are compressed. Along with this, compression occurs in the intestine itself, leading to trophic disorders in this area. In contrast to the above, with obturation intestinal obstruction, the main pathological manifestations occur in the adductor part of the intestine. With the development of dynamic intestinal obstruction, the intestine does not have a specific lesion area, and all pathological processes diffuse. This review article is devoted to analysing literature on the mechanisms of development and manifestation of acute intestinal failure and the features of their manifestation in elderly and senile patients age.
