(Part 6)

Chest pain with dysphagia occurs in DES and related motor disorders Chest pain resembling DES may occur in esophageal obstruction due to a large bolus A prolonged history of heartburn and reflux preceding dysphagia indicates peptic stricture A history of prolonged nasogastric intubation, ingestion of caustic agents, ingestion of pills without water, previous radiation therapy, or associated mucocutaneous diseases may provide the cause of esophageal stricture If odynophagia is present, candidal, herpes, or pill-induced esophagitis should be suspected

In patients with AIDS or other immunocompromised states, esophagitis due

to opportunistic infections such as Candida, herpes simplex virus, or

cytomegalovirus and to tumors such as Kaposi's sarcoma and lymphoma should be considered

PHYSICAL EXAMINATION

Physical examination is important in oral and pharyngeal motor dysphagia Signs of bulbar or pseudobulbar palsy, including dysarthria, dysphonia, ptosis, tongue atrophy, and hyperactive jaw jerk, in addition to evidence of generalized neuromuscular disease, should be sought The neck should be examined for thyromegaly or a spinal abnormality A careful inspection of the mouth and pharynx should disclose lesions that may interfere with passage of food Pulmonary complications such as acute or chronic aspiration pneumonia may be present

Physical examination is often unrevealing in esophageal dysphagia Changes in the skin and extremities may suggest a diagnosis of scleroderma and other collagen vascular diseases or mucocutaneous diseases such as pemphigoid or epidermolysis bullosa, which may involve the esophagus Cancer spread to lymph nodes and liver may be evident

DIAGNOSTIC PROCEDURES

Dysphagia is usually a symptom of organic disease rather than a functional complaint If oral or pharyngeal dysphagia is suspected, VFSS by both a radiologist and a swallow therapist is the procedure of choice Videoendoscopy is currently performed only in specialized centers Otolaryngoscopic and neurologic evaluation are also usually required

If esophageal mechanical dysphagia is suspected on clinical history, barium swallow and esophagogastroscopy with or without mucosal biopsies are the diagnostic procedures of choice In some cases, CT examination and endoscopic ultrasound may be useful For motor esophageal dysphagia, barium swallow, esophageal manometry, esophageal pH, and impedance testing are useful diagnostic tests Esophagogastroscopy is also often performed in patients with motor dysphagia to exclude an associated structural abnormality (Chap 286)
