Chapter 038. Dysphagia (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...

Chapter 038. Dysphagia (Part 6) Chapter 038. Dysphagia (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 largebolus. A prolonged history of heartburn and reflux preceding dysphagia indicatespeptic stricture. A history of prolonged nasogastric intubation, ingestion of causticagents, ingestion of pills without water, previous radiation therapy, or associatedmucocutaneous diseases may provide the cause of esophageal stricture. Ifodynophagia is present, candidal, herpes, or pill-induced esophagitis should besuspected. In patients with AIDS or other immunocompromised states, esophagitis dueto opportunistic infections such as Candida, herpes simplex virus, orcytomegalovirus and to tumors such as Kaposis sarcoma and lymphoma should beconsidered. 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 generalizedneuromuscular disease, should be sought. The neck should be examined forthyromegaly or a spinal abnormality. A careful inspection of the mouth andpharynx should disclose lesions that may interfere with passage of food.Pulmonary complications such as acute or chronic aspiration pneumonia may bepresent. Physical examination is often unrevealing in esophageal dysphagia.Changes in the skin and extremities may suggest a diagnosis of scleroderma andother collagen vascular diseases or mucocutaneous diseases such as pemphigoid orepidermolysis bullosa, which may involve the esophagus. Cancer spread to lymphnodes and liver may be evident. DIAGNOSTIC PROCEDURES Dysphagia is usually a symptom of organic disease rather than a functionalcomplaint. If oral or pharyngeal dysphagia is suspected, VFSS by both aradiologist and a swallow therapist is the procedure of choice. Videoendoscopy iscurrently performed only in specialized centers. Otolaryngoscopic and neurologicevaluation are also usually required. If esophageal mechanical dysphagia is suspected on clinical history, bariumswallow and esophagogastroscopy with or without mucosal biopsies are thediagnostic procedures of choice. In some cases, CT examination and endoscopicultrasound may be useful. For motor esophageal dysphagia, barium swallow,esophageal manometry, esophageal pH, and impedance testing are usefuldiagnostic tests. Esophagogastroscopy is also often performed in patients withmotor dysphagia to exclude an associated structural abnormality (Chap. 286).
