2- Symptoms of Gastrointestinal Diseases

See Table 1

A 43-year old man has persistent dysphagia following cancer of the right buccal space. To treat the cancer, he had radiation therapy and neck dissection. He currently exhibits pharyngeal dysphagia, aspiration, hoarse vocal quality, and right lower facial weakness. He currently receives nutrition through a NG-tube.

3- Approach to the patient with dysphagia

What would be your next measure ?

3- Approach to the patient with dysphagia (continue)

A 64-year-old white woman with a history of breast cancer

treated with lumpectomy and radiation, hypertension, high

cholesterol, and ovarian polyps presents to her primary care

physician complaining of difficulty and pain with swallowing,

as well as occasional chest pain. She indicates that her

problem started with liquids, but has progressed to solids, and

that the food “just gets stuck in my throat.” The chest pain

was once so bad that she took one of her husband’s

nitroglycerin pills and the pain subsided, but it has since

occurred many times. The physician orders an x-ray of the

chest, but it is not diagnostic. Manometry is conducted, and it

shows uncoordinated contractions.

What is the most likely diagnosis?

4- Evaluation of a case

5- Discussing differential diagnoses

A. Breast cancer relapse

B. Diffuse esophageal spasm

C. Esophageal cancer

D. Myocardial infarction

E. Nutcracker esophagus

Answer A is incorrect. Although this patient

has had cancer in the past, she does not seem

to be suffering from it again. Her symptoms

do not indicate any such etiology.

5- Discussing differential diagnoses (continue)

A. Breast cancer relapse×

The correct answer is B. Spasms of the esophagus are characterized by problems with both solids and liquids, causing odynophagia and dysphagia, as well as noncardiac angina. Globus pharyngeus, or the feeling of food stuck in one’s throat, is also very common. Nitroglycerin may actually confuse the diagnosis because it acts to relax the smooth muscle, thereby relieving the pain. X-rays may be helpful in diagnosis by showing what is known as a corkscrew formation of the esophagus. The anatomy of the esophagus may be divided into three parts, and when these three do not contract in a uniform manner as with spasms, then a food bolus may become trapped and cause pain. Manometry establishes the diagnosis by showing these uncoordinated contractions.

B. Diffuse esophageal spasm


Answer C is incorrect. Usually, cancer will cause

dysphagia only for solids and may not cause the

pain this patient is experiencing unless it has

spread beyond the walls of the esophagus.


C. Esophageal cancer×

Answer D is incorrect. A myocardial infarction will

not present with the given history of

progressive dysphagia. Remember that chest pain

does not always translate into a cardiac etiology.


D. Myocardial infarction×

Answer E is incorrect. Very similar to spasms, nutcracker

esophagus differs in the fact that it is characterized by

continuous, coordinated contractions on

manometry. This difference is important with treatment

because spasms may ultimately be treated with a

myotomy, while nutcracker cannot.


E. Nutcracker esophagus×
