Difficulty: MediumGastroenterology and Hepatology

A 48-year-old man is brought to the emergency department due to excruciating lower chest and upper abdominal pain that began 2 hours ago. The pain started abruptly after several episodes of forceful retching and vomiting following heavy alcohol consumption. His temperature is 38.2∘C38.2^\circ\text{C} (100.8∘F100.8^\circ\text{F}), blood pressure is 105/65 mmHg105/65\text{ mmHg}, pulse is 118/min118/\text{min}, and respirations are 24/min24/\text{min}. Physical examination reveals diaphoresis and acute distress. Palpation of the anterior neck and supraclavicular area elicits a crackling sensation. Cardiac auscultation reveals a crunching sound synchronous with the heartbeat.

Arrange the following diagnostic and therapeutic steps in the most appropriate sequential order for managing this patient, assuming the initial contrast study is non-diagnostic but clinical suspicion remains high.

  1. 1Obtain an upright chest radiograph
  2. 2Perform a water-soluble contrast esophagram
  3. 3Perform a barium contrast esophagram
  4. 4Proceed with emergency surgical repair and mediastinal drainage

Answer

The correct sequence is: Obtain an upright chest radiograph -> Perform a water-soluble contrast esophagram -> Perform a barium contrast esophagram -> Proceed with emergency surgical repair and mediastinal drainage.
The patient's presentation of severe chest pain following forceful retching, combined with subcutaneous emphysema and Hamman sign (mediastinal crunch), is the classic presentation of Boerhaave syndrome (spontaneous transmural perforation of the esophagus). The management requires a specific, rapid sequence to confirm the diagnosis while minimizing iatrogenic harm. A chest radiograph is the most appropriate first screening test to identify pneumomediastinum. However, an esophagram is required to confirm the diagnosis and locate the tear for surgery. A water-soluble contrast study is always performed first; if it leaks into the mediastinum, it is easily absorbed and causes minimal tissue reaction. Because water-soluble contrast can miss small perforations, a negative result in a highly suspicious case must be followed by a barium study, which is more sensitive but carries a high risk of chemical mediastinitis if a large leak is present. Once the tear is confirmed and localized, urgent surgical intervention with primary repair and drainage is required.

Step-by-Step Solution

1
Diagnose the underlying condition based on the clinical presentation.
The patient has Boerhaave syndrome (effort rupture of the esophagus), indicated by Mackler triad (vomiting, lower thoracic pain, subcutaneous emphysema) and Hamman sign (mediastinal crunch).
Recognizing the high likelihood of an esophageal perforation dictates an urgent need for sequential diagnostic testing that avoids causing further harm.
2
Determine the best initial rapid screening test.
An upright chest radiograph.
It is fast, non-invasive, and can quickly reveal secondary signs of perforation such as pneumomediastinum or pleural effusions.
3
Select the safest initial confirmatory test to localize the perforation.
A water-soluble contrast esophagram.
Water-soluble contrast minimizes the risk of severe mediastinal inflammation if it leaks through a large defect.
4
Determine the next step if the water-soluble study is negative but suspicion is high.
A barium contrast esophagram.
Water-soluble contrast has a notable false-negative rate for small perforations. Barium is more sensitive and must be used to definitively rule out a tear, but only after a large leak has been excluded.
5
Identify the definitive treatment.
Emergency surgical repair and mediastinal drainage.
Once the perforation is located, surgical intervention is required to repair the defect and prevent fatal sepsis.
