Overview |
|
|
Definition |
|
Generally defined as difficulty in swallowing (or the sensation of difficulty
in swallowing), dysphagia reflects an esophageal or pharyngeal transport
disorder, either from anatomical malformations or from a disruption of the
physiological events in swallowing. Dysphagia can be subdivided into the
following two distinct types, which can occur independently.
- Oropharyngeal dysphagia: Difficulty initiating the act of swallowing,
of moving food from the mouth to the upper esophagus (generally from
abnormalities of the pharynx and upper esophageal sphincter)
- Esophageal dysphagia: Difficulty moving food through the
esophagus
The lifetime incidence of dysphagia is less than 10%. Although all ages are
affected, the prevalence increases with age. No sex
differentiation. |
|
|
Etiology |
|
The causes of oropharyngeal dysphagia (dysphagia for solids or liquids)
include the following.
- CNS: cerebrovascular accident (CVA), Parkinson's disease, brainstem
tumors
- Muscle: myasthenia, polymyositis, thyroid disease, systemic lupus
erythematosus
- Structural: web, Zenker's diverticulum, extrinsic
compression
The causes of esophageal dysphagia include the following.
- Dysphagia for solids only, intermittent: webs, rings, diverticulum,
esophagitis
- Solids only, continuous/progressive: carcinoma (particularly under
age 40), stricture
- Solids and liquids: motility disorder such as diffuse esophageal
spasm, tumor, stricture, esophagitis
Dysphagia in children usually indicates the following.
- Congenital malformations: esophageal atresia, choanal
atresia
- Acquired malformations: corrosive or herpetic esophagitis
- Neuromuscular/neurologic conditions: cerebral palsy, muscular
dystrophy
- GERD
Dysphagia in adults usually indicates the following.
- Structural: tumors (benign and malignant), strictures, rings and
webs, extrinsic compression
- Neuromuscular: achalasia, diffuse esophageal spasm, scleroderma,
myasthenia gravis
- Gastroesophageal reflux disease
(GERD)
|
|
|
Risk Factors |
|
- Smoking
- Recurrent or chronic GERD
- Medications (such as quinine, potassium chloride, vitamin C,
tetracycline, NSAIDs)
- Poor dentition
- Ill-functioning dentures
- Excessive alcohol consumption
- Achalasia
- Esophageal cancer
- Plummer-Vinson syndrome
- Barrett's mucosa
- Hereditary or congenital
malformations
|
|
|
Signs and Symptoms |
|
Oropharyngeal dysphagia is characterized by the following.
- Difficulty initiating swallowing
- Inability to move food into the esophagus
- Choking or aspiration while swallowing
- Coughing while swallowing
- Regurgitation of liquid through the nose
- Aspiration with swallowing
- Weak voice
- Weight loss
Esophageal dysphagia is characterized by the following.
- Pressure sensation in mid-chest
- Sensation of food stuck in the esophagus
- Retrosternal fullness after swallowing
- Weight loss
- Chest pain and other GERD symptoms
- Extended period of time required for
eating
|
|
|
Differential
Diagnosis |
|
- Cardiac-associated chest pain
- Globus hystericus
- Scleroderma
|
|
|
Diagnosis |
|
Because dysphagia is symptomatic of a structural or functional abnormality,
determining the etiology is essential for effective treatment. Avoid dismissing
the symptom as psychosomatic or "globus hystericus." Consultation with a
gastroenterologist is advised. |
|
|
Physical Examination |
|
Determine precisely where the patient's symptoms are felt; whether symptoms
appear with solids, liquids, or both; if the symptoms are intermittent or
progressive. Also, question patients about length of time spent eating (i.e.,
unconsciously chewing food thoroughly). For infants/children, observe sucking
and eating practices.
During evaluation, consider the following.
- Esophageal patency, inflammation
- Airway function
- Pulmonary function
- Cardiac disease
- Nutritional status
- Evidence of aspiration pneumonia
- Symptoms of heartburn
|
|
|
Pathology/Pathophysiology |
|
- Mass lesion, including squamous cell carcinoma and
adenocarcinoma
- Barrett's metaplasia
- Fibrous tissue from a ring, web, or stricture
- Heterotopic gastric mucosa
- Acute or chronic inflammatory change
- Deformities or scars
|
|
|
Imaging |
|
For infants and children:
- X ray of neck, chest
- Contrast X ray
For adults:
- X ray of neck, chest, abdomen
- Barium swallow (cine/video esophagogram)
- Contrast X ray: esophagogram, cine-esophagogram, modified
cine-esophagogram
- CT scan
|
|
|
Other Diagnostic
Procedures |
|
In addition to physical assessment and history, these special tests may be
done:
- Esophagoscopy: particularly relevant for patients with persistent
difficulty swallowing solid food. Disruption of webs and rings during endoscopy
can be therapeutic.
- Esophageal manometry: preferred procedure for esophageal motor
function evaluation (affected by anticholinergics, calcium-channel blockers,
nitrates, prokinetics, sedatives)
- Endoscopic ultrasonography: to diagnose and stage benign and
malignant esophageal neoplasms
- Infants and children: nasogastric tube assessment of esophagus
patency

|
|
Treatment Options |
|
|
Treatment Strategy |
|
Outpatient care is appropriate for patients capable of maintaining nutrition
and with low risk of complications. Hospitalization may be necessary for infants
and children, and for adults with total or near-total obstruction of the
esophageal lumen.
Treatment can include drug therapies, esophageal dilatation, and
surgery. |
|
|
Drug Therapies |
|
Check manufacturers' profiles for possible drug interactions. Liquid forms of
medications may be necessary.
For spasms:
- Nitrates: nitroglycerin, isosorbide (contraindications: early
myocardial infarction, severe anemia, increased intracranial
pressure)
- Anticholinergics: dicyclomine (Bentyl) or hyoscyamine sulfate
(Lepsin) (contraindications: obstructive uropathy, glaucoma, myasthenia gravis,
achalasia)
- Calcium-channel blockers: nifedipine (Procardia), diltiazem
(Cardizem)
- Sedatives/antidepressants: diazepam (Valium), trazodone (Desyrel),
doxepin (Sinequan)
- Smooth-muscle relaxants: hydralazine
For esophagitis:
- H2-blockers: cimetidine (Tagamet), ranitidine (Zantac), nizatidine
(Axid), famotidine (Pepcid)
- Proton-pump inhibitors (for failure of H2-blockers or as initial
therapy): omeprazole (Prilosec), lansoprazole (Prevacid)
- Prokinetic agents: metoclopramide (Reglan), cisapride (Propulsid);
adjunct to acid-suppressive therapy
|
|
|
Complementary and Alternative
Therapies |
|
Herbs can be very effective at decreasing spasms and healing esophagitis.
Homeopathics could be used concurrently for symptomatic
relief. |
|
|
Herbs |
|
Herbs are generally a safe way to strengthen and tone the body's systems. As
with any therapy, it is important to ascertain a diagnosis before pursuing
treatment. Herbs may be used as dried extracts (capsules, powders, teas),
glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless
otherwise indicated, teas should be made with 1 tsp. herb per cup of hot water.
Steep covered 5 to 10 minutes for leaf or flowers, and 10 to 20 minutes for
roots. Drink 2 to 4 cups/day. Tinctures may be used singly or in combination as
noted.
- Licorice (Glycyrrhiza glabra): an anti-inflammatory,
antispasmodic, and analgesic specific for the gastrointestinal tract.
Glycyrrhetinic acid has been shown in studies to aid healing of gastric, peptic,
and mouth ulcers. In patients with hypertension, use deglycerinated licorice to
prevent aggravating hypertension. Prolonged use may lead to pseudoaldosteronism,
which resolves with discontinuation of the herb. The dose is 380 to 1,140
mg/day. Chewable lozenges may be the best form of licorice for treating
GERD.
- Slippery elm (Ulmus fulva): demulcent (protects irritated
tissues and promotes their healing); dose is 60 to 320 mg/day. One tsp. powder
may be mixed with water tid to qid.
In addition, a combination of four of the following herbs may be used as
either a tea or tincture. Use equal parts of the herbs, either 1 tsp. of each
per cup of water and steep 10 minutes tid, or equal parts of tincture 30 to 60
drops tid.
- Valerian (Valeriana officinalis): bitter, sedative, especially
where there is anxiety and/or depression and poor digestion
- Wild yam (Dioscorea villosa): antispasmodic,
anti-inflammatory, especially where there is fatigue from long-term stress or
maldigestion
- St. John's wort (Hypericum perforatum): analgesic,
antidepressant, historically used to treat adhesions, especially where there is
anxiety and/or pain
- Skullcap (Scutellaria lateriflora): antispasmodic, sedative,
nervine, especially with disturbed sleep
- Linden flowers (Tilia cordata): antispasmodic, mild diuretic,
gentle bitter, especially with
dyspepsia
|
|
|
Homeopathy |
|
An experienced homeopath should assess individual constitutional types and
severity of disease to select the correct remedy and potency. For acute
prescribing use 3 to 5 pellets of a 12X to 30C remedy every one to four hours
until acute symptoms resolve.
- Baptesia for patients who can only swallow liquids and gag on
the smallest amount of solids; especially with a red inflamed throat that is
relatively pain free.
- Baryta carbonica for huge tonsils that make it difficult to
swallow even liquids; especially with shyness
- Carbo vegatabilis for bloating and indigestion that is worse
from lying down; especially with flatulence and fatigue
- Ignatia imara for "lump in the throat," back spasms, spasmodic
cough; especially when symptoms appear after grieving
- Lachesis for difficulty swallowing, intolerance to touch
around the throat, and tight
clothes
|
|
|
Patient Monitoring |
|
Discuss etiology and prognosis with patients, including possible need for
repeat dilatations. Dysphagia should not require limits on patients' activities.
Depending on the degree of obstruction, diet may have to be
restricted. |
|
|
Other
Considerations |
|
|
Prevention |
|
Counsel patients (and/or caregivers) to do the following:
- Avoid exacerbating drugs
- Chew thoroughly
- Avoid extremely hot or cold foods
- Do not drink alcohol in excess
- Correct poorly fitting dentures
- Observe infants/children carefully when
eating
|
|
|
Complications/Sequelae |
|
- Aspiration
- Esophageal "asthma"
- Pneumonia
- Barrett's syndrome; esophageal
cancer
|
|
|
Prognosis |
|
Prognosis varies from good for relatively uncomplicated dysphagia (e.g.,
peptic strictures) to poor for dysphagia with cancer etiologies. Speech therapy
may be appropriate for patients who need to learn swallowing
techniques. |
