ABSTRACT

Objective:To evaluate the safety and efficacy of endoscopic ultrasound (EUS)-guided iodine-125 seed implantation to treat dysphagia in patients with advanced esophageal cancer.Methods:Data of 4 patients with dysphagia of advanced esophageal cancer who received EUS-guided iodine-125 seed implantation in Chinese PLA General Hospital between December 2017 and November 2018 were collected in the retrospective study. The evaluation contents included technical success rate of seed implantation, complication, dysphagia grade, tumor size and other follow-up results.Results:Four patients successfully completed EUS-guided iodine-125 seed implantation. No haemorrhage, chest pain, fever, cough or other postoperative complications were reported. Three months after treatment, dysphagia grade reduced from Ⅱ-Ⅳ to 0-Ⅰ, and the tumor size in all patients showed a decrease. After 12-23 months of follow-up, 3 patients were alive, and 1 died due to advance of the cancer.Conclusion:EUS-guided iodine-125 seed implantation is a safe and effective palliative treatment method for dysphagia in patients with advanced esophageal cancer.
