Intestinal obstruction caused by malignant tumors is generally curable and can be treated by general treatment and surgery. 1. General treatment: Continuous gastrointestinal decompression should be carried out to reduce the pressure in the intestinal lumen and alleviate the uncomfortable symptoms. When the lung function is affected, the symptoms of hypoxia can be alleviated through oxygen inhalation. 2. Surgical treatment: if intestinal obstruction is caused by malignant tumor, the cancer should be removed by surgery, and the common surgical methods are intestinal resection and intestinal anastomosis; if tumor infiltration is impossible to be resected, the intestinal obstruction can be lifted by short-circuit surgery; if the condition is more serious, and the physical condition is not suitable for complicated surgery, the obstruction can be lifted by intestinal stoma or intestinal extubation. It is suggested that patients should consult the doctor in time and carry out relevant treatments under the doctor’s guidance, so as to avoid delaying the condition.
