Computed tomography for oesophageal carcinoma: its value to the surgeon.
1992
: Between January 1988 and June 1991, 75 patients with carcinoma of the oesophagus or gastro-oesophageal junction were evaluated by computed tomography (CT). Fifty of these patients underwent operation, allowing 48 cases to have a detailed surgical and pathological verification of CT features. For thoracic oesophageal tumours the accuracy of CT was 59% for fat plane status, 86% for aortic contact, 81% for tracheobronchial tree compression and 66% for direct local invasion. CT was 69% accurate for identifying lymph nodes, of which only 38% contained metastatic deposits. For gastro-oesophageal junction tumours, CT was 74% accurate for fat plane status and 90% accurate for direct local invasion. Accuracy for detecting lymph node involvement was 63%, metastatic tumour being present in 91% of these nodes. By pathological staging, only 15% of all resections could be considered potentially curative. The value of CT was found to be in predicting a palliative or curative resection, and in warning the surgeon about possible infiltration of specific mediastinal or abdominal structures that would be encountered during operative dissection.
