Overview

DES must be differentiated from other diseases that cause chest pain, weight loss and dysphagia (difficulty swallowing), such as Angina, GERD, esophagitis, stricture/webs/rings as well as other motility disorders like nutcracker esophagus and hypertensive LES.

Differentiating DES from other Diseases

Disease	Signs & Symptoms	Findings on barium swallow	Endoscopy	Imaging test
Reflux esophagitis	Dysphagia (from peptic stricture) Heartburn Hoarseness	Poor clearance Free reflux of barium	peptic stricture (advanced cases)	A hiatus hernia may be present below the stricture Lower esophageal pH studies will demonstrate pathologic gastroesophageal reflux
Esophageal carcinoma	Dysphagia (initially for solids, liquids develops with advanced disease.) Weight loss Lymphadenopathy Appetite changes Cachexia	irregular stricture pre-stricture dilatation	Most accurate test for diagnosis esophageal obstruction staging of disease	Biopsy: for definite diagnosis and tumor histology
Systemic sclerosis	Dysphagia Muscle and joint pain Raynaud's phenomenon skin changes (e.g., rash, skin swelling or thickening).	Dysmotility Patulous esophagus	Mucosal damage Peptic stricture (advanced cases)	Serology for Antinuclear antibodies Rheumatoid factor creatine kinase ESR
Nutcracker esophagus	Chest pain Dysphagia	Corkscrew or rosary bead esophagus nonperistaltic contractions	Inconclusive	Manometry: high-amplitude esophageal peristaltic contractions > 220 mm Hg measured after swallowing 10 15 ml of liquid
Pseudoachalasia	Dysphagia Weight loss Lymphadenopathy Appetite changes Cachexia Older patients Underlying malignancy that mimics idiopathic achalasia. Patients tend to be older, duration of symptoms shorter, and weight loss greater and more rapid.	More marked mucosal irregularity Temporary patency of LES	Most accurate test for diagnosis esophageal obstruction staging of disease	Gastroscopic biopsy of gastroesophageal junction and cardia may demonstrate malignancy. Findings at endoscopy, barium swallow, and manometry may be indistinguishable from achalasia.
Chagas disease	Dysphagia myocarditis Blepharitis Toxic megacolon	oesophageal dilatation stasis of barium	dilated esophagus thickened LES (muscular ring)	Giemsa stain: Trypanosoma cruzi. PCR for trypanosome subtype
Hypertensive LES	Dysphagia chest pain Weight loss			Manometry: Basal LES pressure >40 mm Hg
Esophageal candidiasis	Dysphagia Immunocompromised History of corticosteroid	shaggy" appearance (plaques) irregular contours in the lower third	ulceration plaques and pseudomembranes tiny nodules, polypoid folds (advanced cases)	creamy white or yellowish plaques (thrush) in oropharynx or hypopharynx; may be normal exam
plummer vinson syndrome
