Hypopharyngeal and oesophageal outpouchings and dysmotility

Abstract

Some aspects of the extensive pathology of the hypopharynx and oesophagus are discussed: abnormal outpouchings of the lateral pharyngeal wall; correlation between dysfunction of the pharyngooesophageal junctions and Zenker's diverticulum; correlation between oesophageal dysmotility and the presence of a pulsion diverticulum and intramural diverticulosis. A discussion of the principal causes of oesophageal dysmotility is followed by a detailed account of two manifestations of dysmotility: diffuse oesophageal spasm and diffuse oesophageal hypertrophy.
