Endoscopic ultrasound scanning of the upper gastrointestinal canal

摘要: Endoscopic ultrasound scanning (EUL) of the upper gastro-intestinal canal has rendered apparently very meticulous assessment pathological conditions in and around oesophagus, stomach duodenum possible during recent years. On account close contact with mucosa, high-frequent transducer great solubility capacity are employed. The wall gastrointestinal may thus be presented subdivided into five layers. gastroscope most employed at present is lateral visualizing a mechanically rotating sector scanner mounted distal to optic. basis literature, technique examination hitherto indications for EUL reviewed. International attention been focussed on employment preoperative subdivision tumours stomach, pancreas biliary passages stages. Individual centres have reported promising results compared existing forms such as CT, conventional radiography, endoscopy external scanning. It concluded that necessary apparatus not yet fully developed. In addition, more numerous extensive prospective investigations before possibly considered routine method examination.
