Case 1 Answers

1. Correct Answer C. Esophageal dilatation with air-fluid level is the most notable abnormality on the PA view of his chest x-ray. This is often seen in an advanced achalasia as the lower esophageal sphincter as constricted and not allowed any liquid or solids to pass causing significant dilatation of the esophagus. No acute infiltrate is noted in the chest x-ray to suggest pneumonia.  No increased pulmonary vascular congestion is appreciated. Pulmonary embolism should be considered however no shortness of breath or history of DVT/PE exists.  No Westermark Sign is noted on his chest x-ray.

2.  Correct Answer A. Barium Swallow is the preferred initial screening test if achalasia is suspected.  Extensive esophageal dilatation is typically only noted 1 chest x-ray in advanced cases. A CTA thorax is the preferred modality for diagnosis of acute pulmonary embolus.  A d-dimer should only be used in the low risk patient’s suspected of having a pulmonary embolus with a Well’s score of less than 2. An echocardiogram is also a good screening test for both acute pulmonary embolism with right heart strain as well as for acute heart failure however it serves no role in the diagnosis of achalasia.

 3.  Correct Answer B. Calcium Channel Blockers or Nitrates are the preferred initial pharmacotherapy for smooth muscle relaxation in patients with achalasia.  Ceftriaxone and doxycycline are preferred for patient’s being admitted with acute community acquired pneumonia. Heparin bolus with subsequent drip is preferred in patients with acute pulmonary embolus that may undergo PCI. Fondaparinux with Coumadin overlap is preferred for stable patient’s with acute pulmonary embolus.
