Intestinal obstruction is a common surgical emergency, and most patients need to be hospitalized for about 1 week. Intestinal obstruction is an obstacle to the passage of intestinal contents caused by various reasons, which can not only cause changes in the morphology and function of the intestinal canal, but also lead to a number of systemic pathological changes, which can be life-threatening in serious cases. The treatment principle is to correct the systemic physiological disorder caused by intestinal obstruction and release the obstruction, and the appropriate treatment method can be based on the cause, nature, location, systemic condition and severity of intestinal obstruction. For patients with non-surgical treatment, gastrointestinal decompression, correction of water and electrolyte disorders and acid-base balance, and prevention and control of infection are required during hospitalization. For surgical treatment, patients need to release the obstruction and remove the cause of the disease. Patients are advised to follow the correct medication and regular review after discharge, and to observe the healing of the incision after surgery, and to seek medical attention in case of infection.
