The duration of stent placement for intestinal obstruction is generally relatively limited, probably within 3-6 months. This is because there are many causes of intestinal obstruction, and the vast majority of stents are placed in elderly and frail patients, patients who cannot tolerate surgical treatment, or patients whose local intestinal lesions cannot be removed, and the causes are mainly stenosis caused by intestinal cancer or inflammatory bowel disease. Stent placement is a helpless choice, its role is equivalent to using wooden sticks to support the collapsed bridge, and then make the intestine limited patency, but the patient’s disease is not really treated, so with the development of the disease, the diseased tissue will gradually press the stent again to cause stenosis, or fill up the stent space to cause obstruction, which takes about 3-6 months. In conclusion, stent placement for intestinal obstruction is only a buffer treatment, but not the fundamental measure to cure the disease, and surgical resection is the best method, but the actual situation of the patient needs to be analyzed.
