Fully Covered Esophageal Prosthesis (FC-SEMS)

Esophageal cancer is the seventh most common type of cancer in the world, with an estimated global incidence of 604,100 new cases per year. The main symptom of esophageal cancer is dysphagia, associated or not with weight loss. Unfortunately, due to asymptomatic presentation in the early stages, more than half of patients are diagnosed in advanced stages of the disease, becoming ineligible for treatment with curative intent. In this sense, chemotherapy and radiotherapy are the pillars of palliative treatment, often regressing the injury and improving symptoms. However, some patients persist with dysphagia. In this scenario, esophageal prostheses are one of the main tools in the palliative treatment of esophageal cancer dysphagia, obtaining rapid and lasting relief of dysphagia. This study aims to compare fully covered (FC-SEMS) and partially covered (PC-SEMS) esophageal prostheses in this context, evaluating the number of reinterventions in each group, as well as the occurrence of adverse events. However, it is expected that with the data obtained it is possible to develop clearer and more effective protocols in the palliation of malignant dysphagia of esophageal stenosis.
