Die sonographische Beurteilbarkeit des Hypopharynx und des extrathorakalen Ösophagus: Möglichkeiten und Grenzen für Staging und Therapieplanung

TL;DRAbstract

Sonographic examination of the hypopharynx and the extrathoracic oesophagus can be difficult. Therefore, most surgeons prefer to utilise CT or MRI scanning. Surgery is planned on the basis of endoscopic findings combined with radiologic information. The aim of the present prospective study was to demonstrate that the combination of ultrasonography and endoscopy provides a sufficient basis for the planning of surgical interventions in patients suffering from hypopharyngeal cancer or cancer of the proximal oesophagus. In 10 patients with squamous cell carcinoma of the hypopharynx/proximal oesophagus (8T4, 2T2) and 2 patients with a T4 squamous cell carcinoma of the larynx, both preoperative CT and ultrasound were performed and compared with the extent of the tumour seen during endoscopy. With ultrasound, the T4 tumours of the hypopharynx were recognized well as opposed to the T2 tumours which were not detected. The CT results were similar. An infiltration of the proximal oesophagus was s
