ANATOMY OESOPHAGUS

• In clinical practice, most

radiologists and surgeons divide the oesophagus into three parts:

• upper third, from the cricopharyngeus to the superior portion of the aortic arch; • middle third, from the superior portion of the aortic arch to the inferior pulmonary vein; • Distal third, from the inferior pulmonary vein to the gastroesophageal junction

The behaviour and treatment of oesophageal cancer vary with these anatomic locations .
