Patient: Esophageal stenosis, easy to choke on food. I had surgery on December 19, 2008 for pancreatic cancer, and then had chemotherapy twice. Thank you! Chen Xueqing, Department of Gastroenterology, The First Affiliated Hospital of Guangzhou Medical College: The stenosis after surgery depends on the situation, you can’t put stents in everything. If the stenosis is close to the incisors, stenting is not recommended. However, it should be possible to perform probe expansion. The cost is not expensive, more than a thousand will be enough. However, the stenosis may be re-stenosed after dilation and will need to be re-dilated. If the stenosis is at a safe enough distance from the incisors, you can put a stent in. If the stent can be retrieved, it can be removed after the stenosis is fully expanded, and the cost is more than 6000 (domestic stent).
