Benign esophageal stricture describes a narrowing or tightening of the esophagus. The esophagus is the tube that brings food and liquids from your mouth to your stomach. Benign esophageal stricture typically occurs when stomach acid and other irritants damage the lining of the esophagus over time.
Esophageal dilation is a procedure that allows your doctor to dilate, or stretch, a narrowed area of your esophagus [swallowing tube]. Doctors can use various techniques for this procedure. Your doctor might perform the procedure as part of a sedated endoscopy.
The esophagus is a long, thin, and muscular tube that connects the pharynx throat to the stomach. It forms an important piece of the gastrointestinal tract and functions as the conduit for food and liquids that have been swallowed into the pharynx to reach the stomach. The esophagus is about inches 25 centimeters long and less than an inch 2 centimeters in diameter when relaxed. It is located just posterior to the trachea in the neck and thoracic regions of the body and passes through the esophageal hiatus of the diaphragm on its way to the stomach.
During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The wall of the esophagus from the lumen outwards consists of mucosasubmucosa connective tissuelayers of muscle fibers between layers of fibrous tissueand an outer layer of connective tissue. The mucosa is a stratified squamous epithelium of around three layers of squamous cells, which contrasts to the single layer of columnar cells of the stomach.

Anatomy knowledge is the basic stone of healing diseases. Arteries, veins, wall structure, nerves, narrowing, curves, relations with other organs are very important to understand esophagial diseases. In this chapter we aimed to explain anatomical fundementals of oesophagus.
The esophagus is the muscular tube that carries food and liquids from your mouth to the stomach. You may not be aware of your esophagus until you swallow something too large, too hot, or too cold. You may also notice it when something is wrong.
Previous data for esophageal lengths are based on age related groups or cadaveric examination, both of which are improper for application to various individualized procedures. Because of the variability in height for any given age and longer length in vivo, lindividualized approximation is needed. Thus, we measured various anatomical levels of the esophagus using a flexible endoscope and correlated these data with measurable external body intervals.
