Intestinal obstruction is a relatively dangerous and common emergency condition in general surgery. It is a disease caused by an obstruction to the passage of intestinal contents, categorized by its causes into mechanical intestinal obstruction, dynamic intestinal obstruction, and vascular intestinal obstruction, among which vascular intestinal obstruction is particularly dangerous. Based on blood circulation in the intestinal wall, it is divided into simple intestinal obstruction and strangulated intestinal obstruction, with strangulated intestinal obstruction being more dangerous as it can easily lead to ischemic necrosis of the intestines. According to the degree of obstruction, it is classified into partial intestinal obstruction and complete intestinal obstruction, with the latter being more dangerous. Intestinal obstruction, especially strangulated or vascular intestinal obstruction, can lead to obstructed blood circulation in the intestinal wall, resulting in ischemic necrosis and possibly perforation, making it a very dangerous condition.
