Intestinal obstruction is the inability of intestinal contents to function normally and pass smoothly through the intestine. The common causes include 1. mechanical intestinal obstruction caused by tumor, fecal mass, adhesion band compression, etc.; 2. paralytic intestinal obstruction caused by diffuse peritonitis, retroperitoneal hematoma, etc.; 3. hemodynamic intestinal obstruction caused by mesenteric vascular embolism or thrombosis, etc. The main clinical manifestations include abdominal pain, vomiting, abdominal distension, and cessation of defecation from the anal canal. Treatment methods include 1. conservative treatment, mainly water fasting, gastrointestinal decompression, anti-inflammatory rehydration.2 surgical treatment, mainly applicable to strangulated intestinal obstruction, intestinal obstruction caused by tumor, intestinal obstruction caused by congenital intestinal malformation and patients whose non-surgical treatment is ineffective.
The purpose of surgery is mainly to 1 release the obstruction 2 remove the diseased intestinal canal, including removal of necrotic intestinal break, removal of intestinal tumor, inflammatory stenosis segment, etc. 3 reconstruct intestinal patency, including performing intestinal resection anastomosis, short-circuit surgery, proximal enterostomy, etc. The prognosis of surgery is mainly related to the type of intestinal obstruction, the general condition of the patient, and whether the surgery is timely.
