The effect of interventional treatment for esophageal cancer can reach about 2-3 months. If the bleeding area can achieve rapid hemostasis through interventional methods, it can be maintained for a longer period of time. If the ulcer is treated through interventional methods, the ulcer surface, the ulcer itself will form a re-shedding of tissues during the healing process, leading to another bleeding, which may take 2-3 weeks. Esophageal cancer causes obstruction in the lumen of the esophagus, which affects the patient’s eating. Interventional placement of esophageal stents can open up the obstructed area and restore the patient’s normal diet, which can make the patient’s symptoms improve rapidly. Because the cancer tissue cannot be completely destroyed, it will grow again during the process and compress the stent again, so it usually lasts for about 3 months.
