EUS of the neck: A comprehensive anatomical reference for the staging of head and neck cancer (with videos)

Abstract

The use of EUS has application in the nodal staging of head and neck cancer. The technique and the anatomy of head and neck region using EUS have not been described. EUS from three stations in thoracic esophagus, cervical esophagus, and hypopharynx can allow imaging of head and neck. In this article we describe the normal structures from the three stations. The EUS imaging of head and neck can give relevant and additional information in malignancies of head and neck.

Advances in the prevention and treatment of esophageal stricture after endoscopic submucosal dissection of early esophageal cancer

“…[ 4 , 5 , 6 ] In recent years, endoscopic ultrasound has developed rapidly and played an important role in the treatment of pancreatic, gallbladder, and liver diseases. [ 7 , 8 , 9 ] Because of its unique ability to locate lesions, endoscopic ultrasound facilitates the detection, staging, and treatment of esophageal diseases, [ 10 , 11 ] which is of immense significance for the determination of tumor size, margin, and internal echo structure. [ 12 ] However, postoperative esophageal stricture is a major ESD-related complication, the incidence of which is associated with the size of the lesion and the range of circumferential mucosal defects; [ 13 ] it can cause severe dysphagia and an appreciable decrease in the quality of life of patients, thus becoming a major issue to be tackled after operation.…”
