How to classify the etiology of intestinal obstruction

Intestinal obstruction can be divided into mechanical intestinal obstruction, dynamic intestinal obstruction, vascular intestinal obstruction, pseudointestinal obstruction and other types, its diagnosis and treatment need a comprehensive variety of examination methods. Intestinal obstruction can be divided into the following categories according to etiology: 1. Mechanical intestinal obstruction: This type of intestinal obstruction is the most common, accounting for about 3/4 of intestinal obstruction. The main causes of mechanical intestinal obstruction are narrowing of intestinal lumen and obstruction of intestinal contents caused by various reasons, such as intestinal tumor, intestinal adhesion, hernia, ascarid obstruction, etc. 2. Dynamic intestinal obstruction: caused by intestinal muscle dysfunction, rarely seen, no organic intestinal stenosis. The causes can be divided into paralytic intestinal obstruction and spastic intestinal obstruction. 3. Vascular intestinal obstruction: due to blood circulation disorders in mesenteric vessels, resulting in loss of intestinal vitality, followed by intestinal obstruction. Common in mesenteric vascular embolism or thrombosis. 4. Pseudointestinal obstruction: due to nerve or muscle lesions caused by intestinal wall muscle dysfunction. 5. Others: such as according to the degree of intestinal obstruction divided into complete and incomplete intestinal obstruction; Intestinal obstruction can be classified into high and low obstruction according to the site of occurrence. In addition, intestinal obstruction can be classified according to the cause, site of lesion, and severity of onset. Different types of intestinal obstruction are treated differently, so diagnosis is especially important. For patients suspected of intestinal obstruction, doctors usually perform detailed medical history collection, physical examination, laboratory examination and imaging examination to confirm the diagnosis and formulate corresponding treatment plan.
