Small bowel obstruction is a common surgical acute abdomen, with high rates of missed diagnosis, misdiagnosis, mortality and disability. The majority of patients with small bowel obstruction can be relieved by early non-operative treatment and intestinal obstruction catheter. However, there are still many controversies about the window of observation, the time of emergency operation and the method of operation. In recent years, the basic and clinical research on small bowel obstruction has made further progress, but there is no authoritative reference in clinical practice, and there is no relevant consensus and guidelines to standardize the diagnosis and treatment of small bowel obstruction in China. Accordingly, on the initiative of the Chinese Society for Parenteral and Enteral Nutrition and Enhanced Recovery after Surgery Branch of China International Health Care Promotion Exchange Association. The experts in this field of our country constitute the editorial committee, and refer to the main results of the current domestic and foreign research. According to the GRADE system of evidence quality assessment and recommendation intensity grading, the Chinese expert consensus on the diagnosis and treatment of small bowel obstruction was formulated for the study and reference of related specialties. It is expected to improve the overall level of diagnosis and treatment of small bowel obstruction in our country.
