Vascular Diseases, Motility Disorders, and Mechanical Laceration in the Esophagus

Abstract

This chapter summarizes the endoscopic findings of esophageal varices, esophageal motility disorders, and Mallory–Weiss syndrome. To accurately determine these lesions, broad knowledge of the diverse esophageal diseases is required. Esophageal varix is the most common vascular lesion of the esophagus that is observed during the endoscopic examination. Esophageal motility disorders are diagnosed with special equipments that measure motor and sensory function. Sometimes, motor dysfunction such as achalasia or diffuse esophageal spasm can be recognized during endoscopic examination. Mallory–Weiss syndrome is a common cause of upper gastrointestinal bleeding. In this chapter, the diagnostic findings are shown with typical endoscopic pictures.
