Oesophageal Surgery

Oesophageal surgery is performed for conditions of the oesophagus. Oesophagus is an organ in vertebrates which consists of a muscular tube through which food passes from the pharynx to the stomach. During swallowing food passes from the mouth through the pharynx into the esophagus and travels to the stomach. The oesophagus passes through posterior mediastinum in thorax and enters abdomen through a hole in the diaphragm. It is usually about 25–30 cm long and connects the mouth to the stomach. Due to the inferior pharyngeal constrictor muscle, the entry to the esophagus opens only when swallowing or vomiting.
