title: Esophagoscopy and endoscopic esophageal ultrasound in the assessment of esophageal function.
abstract: Esophagoscopy is an ideal method to detect mucosal or structural abnormalities of the esophagus and proximal stomach. The exclusion of malignant dysphagia is the prime role of esophagoscopy in assessment of esophageal function. Esophagoscopy and biopsy are mandatory for mucosal assessment of patients with gastroesophageal reflux disease (GERD). Indirect and sometimes subtle evidence of abnormal esophageal motility is a valuable and underused aspect of esophagoscopy in the evaluation of swallowing disorders. Esophagoscopy has multiple roles in the appraisal and treatment of esophageal motility disorders, including the detection of secondary or pseudoachalasia, placement of manometry catheters, and dilation of peptic strictures caused by GERD associated with disorders such as scleroderma.
