    Journal: Ann R Coll Surg Engl; 2000 Sep; 82(5):311-7. PubMed ID: 11041028.
    Abstract:
    BACKGROUND: Modern management of upper gastro-intestinal cancer demands accurate pre-operative staging. In continental Europe and Japan, endoscopic ultrasound (EUS) is established as the investigation of choice for local staging of these cancers, but British experience with this technique is limited. METHODS: A retrospective review of the medical records of patients with oesophageal or gastro-oesophageal junction tumours during our first 3.5 years' experience with EUS was undertaken and the findings at EUS correlated with the pathology of the resected specimen. RESULTS: A total of 124 patients (86 males), with a mean age of 64.5 years, underwent EUS: 84 had adenocarcinoma and 26 squamous cell carcinoma. There were 3 failed EUS examinations, 42 patients did not have surgery for a variety of reasons, and 10 patients had pre-operative chemoradiotherapy. In the remaining 69 patients, correlation for T stage showed an accuracy of EUS of 80% and for N staging of 54% overall. Comparison of the initial 2 years with the final 18 months showed no change in the T staging accuracy but an improvement in the N staging accuracy from 50% to 60%. CONCLUSION: Once initial experience has been gained, EUS is an accurate procedure for T and N staging of tumours of the oesophagus and gastro-oesophageal junction. It should be included with other imaging modalities, such as CT scanning, in the pre-operative assessment of these tumours.
