Intestinal obstruction can be categorized as mechanical intestinal obstruction, dynamic intestinal obstruction and hemodynamic intestinal obstruction. Different categories of intestinal obstruction have different etiologic and causative factors. 1. Mechanical intestinal obstruction: ① Extra-intestinal factors, such as adhesive band compression, tumor compression and so on. ② Intestinal wall factors, such as intussusception, inflammatory stenosis, tumors and so on. ③ Intestinal lumen factors, such as foreign body, fecal matter, gallstone blockage, etc. 2. Dynamic intestinal obstruction: nerve inhibition or toxin stimulation resulting in loss of peristalsis, which can occur in patients with acute enteritis, intestinal dysfunction or chronic lead poisoning. 3. Hematogenous intestinal obstruction: mesenteric vascular embolism or thrombosis, so that the intestinal blood flow obstruction, intestinal contents can not run normally, thus triggering blockage. If you suffer from intestinal obstruction, it is recommended to seek medical treatment in time, early detection and early treatment, so as to avoid delaying the condition.
