Intestinal obstruction is a common abdominal emergency in surgery, which can be categorized into mechanical, kinetic and hemodynamic according to the etiology, no matter what kind, gastrointestinal decompression should be given first, and then the follow-up treatment should be decided according to the etiology. Gastrointestinal decompression (i.e. gastric drainage) can reduce the gas and liquid in the gastrointestinal tract, reduce the expansion of intestinal lumen, facilitate the blood circulation of the intestinal wall, reduce the edema, and make the intestinal collaterals which are not twisted to be heavy reset themselves to restore the patency, which is one of the main measures for the treatment of intestinal obstruction. Mechanical intestinal obstruction is the most common type, the principle of treatment is to lift the obstruction and remove the cause. If the gastrointestinal decompression, rehydration and other conservative treatment is ineffective, usually take adhesion release surgery, enterotomy to remove intestinal stone, etc., intussusception or intestinal torsion reset surgery. Power intestinal obstruction is mostly paralytic, which is common after laparotomy, abdominal trauma or peritonitis, usually given gastrointestinal decompression, rehydration fluids to correct the water electrolyte disorders, prevention and treatment of infections and other conservative treatments can be recovered on their own. Hematogenous intestinal obstruction is caused by various reasons of intestinal blood transport disorders, often followed by intestinal necrosis, need to be operated as soon as possible, according to the degree of obstruction and obstruction of intestinal inactivation of the decision of surgical methods. The condition of intestinal obstruction develops rapidly and progresses extremely fast, therefore, it is recommended that once diagnosed, it should be treated actively, and if conservative treatment is ineffective, early surgical treatment should be considered.
