Abstract: Malignant bowel obstruction is a common tumor complication secondary to digestive tract tumors and gynecological tumors. Individualized treatments were conducted to the patients with malignant bowel obstruction according to comprehensive multi-disciplinary opinions on tumor internal medicine and tumor surgery, intestinal function protection and recovery as core idea, nutritional therapy as the cornerstone, and personalized therapies such as intestinal stents, palliative surgery, low-dose chemotherapy, and symptomatic treatment. Taking intestinal function protection and recovery as core idea, the blind spots of knowledge at present through clinical practice was discovered from clinical classification to the decision-making of treatment in order to make a macroscopic, comprehensive and systematic understanding of malignant bowel obstruction, to ultimately improve the quality of life and prolong survival time of patients, and to provide decision-making reference for the multidisciplinary comprehensive treatments of intestinal function protection and recovery in malignant bowel obstruction patients.
