Placement of particle esophageal stent The successful placement of particle esophageal stent for esophageal cancer patients by Zizhong Du of the Department of Oncology and Vascular Disease Intervention of our hospital marks a new level of particle therapy technology in our hospital. It is at the forefront of particle therapy for esophageal cancer in the province. The treatment methods of esophageal cancer mainly include Western medicine treatment and Chinese medicine treatment, and its Chinese and Western medicine treatment is divided into radiotherapy, chemotherapy, surgery and the emerging electrochemical intervention and particle stenting treatment, each of which has certain indications. However, most of the cancers are found in the middle to late stage. At this time, particle stenting therapy comes into being, which brings a boon to the majority of esophageal cancer patients, especially the middle and advanced stage esophageal cancer patients! Interventional infusion embolization with particle stenting technology is very effective in treating early, middle and late stage esophageal cancer. Interventional infusion embolization is especially suitable for patients who miss surgical treatment of esophageal cancer, and it is also very suitable for patients who are old and frail with many comorbidities. Interventional irrigation embolization with particle stenting technique can be used in a wide range of cases, even if the patients with esophageal cancer or cardia cancer have already reached the middle or late stage, or if they are too old, have many comorbidities, are weak, or are unable to receive surgery or other treatments due to physiological defects. After the treatment of interventional perfusion embolization, the blocked part of esophagus of esophageal cancer patients has become relatively unobstructed. In this state, the placement of particle stent can achieve the purpose of killing the remaining cancer cells, inhibiting the growth of tumor and preventing the blockage of esophagus again. Therefore, particle stent technology is an important and effective therapeutic measure after the interventional perfusion embolization treatment, which can not only open up the esophageal lumen for the smooth passage of food, but also reduce the side damage of radiotherapy, so that the treatment of esophageal cancer and cardia cancer can be safe, effective and complete. In conclusion, the treatment of esophageal cancer should be continued after surgery in order to achieve the best treatment effect. Moreover, with the continuous research on interventional treatment of esophageal cancer, postoperative interventional treatment plays an increasingly important role in the treatment of esophageal cancer, and patients can choose scientific and reasonable treatment methods according to their specific conditions to achieve satisfactory treatment results.
