This chapter discusses diseases of oesophagus including dysphagia, where the commonest sites for impaction of foreign bodies are at the level of cricopharyngeus, at the level of arch of aorta, hiatus or at the level of benign or malignant strictures. Many types of foreign bodies can be swallowed by the different subjects. The patient often points towards the site of impaction of foreign body, particularly if it is lodged in the upper part of oesophagus. Oropharynx, base of tongue and tonsillar areas should be examined for any foreign body or signs of inflammation. Spontaneous expulsion of foreign body is very rare and best management is removal of foreign body under local or general anaesthesia. Barium swallow shows pencil tip appearance in achalasia cardia and rat tail appearance with mucosal destruction in carcinoma oesophagus. Sharp objects are removed very carefully without causing damage to the walls of oesophagus.
