ANATOMY

Detailed explanation-1: -The esophagus is a hollow, muscular tube that connects the throat to the stomach. It lies behind the trachea (windpipe) and in front of the spine. In adults, the esophagus is usually between 10 and 13 inches (25 to 33 centimeters [cm]) long and is about ¾ of an inch (2cm) across at its smallest point.

Detailed explanation-2: -Lower thoracic: from midway between tracheal bifurcation and gastroesophageal junction to GE junction, including abdominal esophagus; 32-40 cm.

Detailed explanation-3: -The esophagus is a 25-cm long muscular tube that connects the pharynx to the stomach. The length of the esophagus at birth varies between 8 and 10 cm and measures about 19 cm at age 15 years.

Detailed explanation-4: -Fifty-three percent of the examined population had “esophageal” length shorter than 38 cm, whereas 99% of patients with normal endoscopy had “esophageal” length of 38-40 cm. Linear correlation was found between “esophageal” length and height, but not with weight.

Detailed explanation-5: -Esophagus is a muscular tube-like organ that originates from endodermal primitive gut, 25–28 cm long, approximately 2 cm in diameter, located between lower border of laryngeal part of pharynx (Figure 1) and cardia of stomach.
