Transosseus azygogragpy through the rib was performed in 154 patients including 115 with thoracic esophageal cancer. In determining operative indication of thoracic esophageal cancer, azygography was found to be useful when the level, form and direction of infiltration in esophageal filling defect was simultaneously considered. Radical operation was impossible in patients with abnormal azygography and with esophageal filling defect measuring 9cm in length. Diagnostic value of azygography was less in patients whose center of the esophageal filling defect was upper than the tracheal bifurcation and lower than the 8th thoracic spine. However, diagnostic value of the azygography was high in patients with esophageal filling defect locating between the 7th thoracic spine and tracheal bifurcation, because operability of those with normal azygography was high. In diagnosis of mediastinal recurrence of cancer following radical operation of thoracic esophageal cancer, azygography was helpful when combined with sagital tomography of the mediastinum.
