Size of the Esophagus

Introduction

The esophagus varies in size from person to person.  There is a fluctuation in size within one person as the muscular forces with swallowing alter the overall length by upto 2cm.  On average, the esophagus ranges between 20-30cms.

The overall width is approximately 2cm but it too varies with the width of a swallowed bolus.  Various conditions can cause significant changes in the size of the lumen.  Achalasia, for example, can result in a diffusely dilated esophagus, whereas benign and malignant stricture usually cause focal narrowing.

The overall length of the esophagus varies to some extent, generally, in accordance with the length of the trunk of the individual. The average length of the esophagus itself is 24 cm, which is approximately 10 inches.   The width or diameter of the esophagus varies considerably with its state of tonus, but the average resting width is given as approximately 2 cm.
