In the form of muscular tube extending to the stomach from esophageal thin-walled, hollow organ. Above the sixth cervical vertebra, is located below the level of the eleventh thoracic vertebra. In general, males 25 cm (23-30 cm), females 23 cm (20-26 cm) is considered. Teeth up to 15 cm for men in part, for females 14 cm. From the stomach up to the teeth with a combined area of 2 cm shorter than the average 38-42 cm and females. Expands to a width of 2.5-3 cm is full when empty, 1-1.5 cm. (Esophageal carcinoma)
Anatomically divided into three sections;
1. Cervical esophagus: level up to level with the first portion of the thoracic spine.
2. Thoracic esophagus: the first extends from the thoracic spine part of the esophagus.
3. Abdominal esophagus: esophagogastric junction from ending part.
Adjacent to the esophagus, muscles, arteries and organs, causing four significant stenosis;
1.The most narrow place, the upper region of the muscle caused by stenosis.
Stenosis of the middle region of the curve 2.Wall of the esophagus.
3. The middle region of the left main bronchus stenosis çaprazlamasıyla wall of the esophagus.
4.Hiatus and the gastroesophageal sphincter stenosis created by the bottom.
Of the esophagus has a rich lymphatic network. Lymphatic drainage longitudinal direction, up or down may be true. Especially in the lamina propria, muscularis mucosa and submucosa in the intramucosal and submucosal carcinoma because of the spread of the lymphatic network is very common.
Lymphatics of the esophagus and inferior thyroid artery, bronchial and esophageal arteries and the left gastric artery (celiac axis) through the following internal jugular lymph nodes, subcarinal, para-aortic, paratracheal, paracardiac and celiac lymph nodes will be drained.
