[Significance of the esophagogram compared to computed tomography in esophageal cancer].

A comparison of the oesophagogram and computed tomography has shown that there is angulation of the axis of the oesophagus in 75% of patients with perioesophageal tumour spread. This angulation is more common due to tumour in the younger patient. Longer tumours tend to show deeper infiltration into the peri-oesophageal tissue, although its frequency is not necessarily increased. Tumours longer than 8 cm. show infiltration in about 80% of cases.
