Endoscopic ultrasonography of the digestive tract provides for a precise ultrasonic study of the accessible gastrointestinal walls (oesophagus, stomach, duodenum, rectum) and, through these walls, of the adjacent organs (lymph node clusters, posterior mediastinum, pancreas, extrahepatic biliary ducts and perirectal environment). This method is better than computerized tomography to evaluate the local and regional extension of oesophageal and cardial carcinomas producing little or no stenosis and of gastric and rectum carcinomas and lymphomas. It is the examination of choice to detect a peri-anastomotic recurrence of these cancers and to evaluate submucosal tumors of the digestive tract. This method, without morbidity is better than computerized tomography or ultrasonography in the aetiological diagnosis of obstacles in the biliary tract and in the diagnosis and pretherapeutic assessment of pancreatic cancers or endocrine tumors.
消化道内镜超声检查可对可触及的胃肠道壁（食管、胃、十二指肠、直肠）进行精确的超声研究，并通过这些壁对相邻器官（淋巴结群、后纵隔、胰腺、肝外胆管和直肠周围环境）进行研究。对于评估食管和贲门癌局部和区域扩展（产生很少或没有狭窄）、胃癌、直肠癌和淋巴瘤，这种方法优于计算机断层扫描。它是检测这些癌症吻合口周围复发以及评估消化道黏膜下肿瘤的首选检查方法。在胆道梗阻的病因诊断、胰腺癌或内分泌肿瘤的诊断及治疗前评估方面，这种无并发症的方法优于计算机断层扫描或超声检查。
