The four major symptoms of intestinal obstruction are abdominal pain, abdominal distension, nausea, and anal cessation of defecation. Spastic intestinal obstruction can be characterized by abdominal pain, abdominal distension, and anal cessation of defecation, stomach distension, and lack of defecation for several days, but vomiting is not always obvious. The treatment of spastic intestinal obstruction generally follows the conventional treatment plan of intestinal obstruction, including fasting, gastrointestinal decompression, systemic rehydration, correction of systemic internal environmental disorders and anti-infection. In addition, drugs to reduce gastrointestinal secretion, symptomatic treatment such as antispasmodic treatment, and nutritional support can be used, which are generally treated by the above conservative methods.
