A. 20cm
B. 25cm
C. 30-35cm
D. 40cm
Answer
The esophageal length is anatomically defined as the distance between the cricoid cartilage and the gastric
orifice. It ranges in adults from 22 to 28 cm (24 ± 5 SD), 3 to 6 cm of which are located in the abdomen.
The shortest distance between the cricoid cartilage and the celiac axis is the orthotopic route in the posterior mediastinum, being 30 cm. The retrosternal (32 cm) and the subcutaneous route (34 cm) proved to be
longer
