23
Q

Dx of Boerhaave syndrome

A

CT chest
Water-soluble contrast Esophagram

24
Q

Findings on CT characteristic of Boerhaave syndrome

A
  1. Esophageal wall edema
  2. Esophageal wall thickening
25
Q

Why is Water-soluble contrast preferred to Barium contrast in Esophagography?

A

Barium induces mediastinal inflammation

26
Q

Findings on Chest x-ray (not diagnostic) in Boerhaave syndrome

A
  1. U/L pleural effusion (usually left)
  2. Widened mediastinum (air & fluid)
  3. Pneumomediastinum

Can be -ve in early cases

27
Q

Characteristics of Pleural Effusion analysis in Boerhaave syndrome

A
  1. Inc salivary amylase
  2. pH <6
  3. Undigested food

Exudative fluid

28
Q

Management of Boerhaave symdrome

A
  1. IVF (pt is NPO)
  2. IV PPI
  3. IV broad-spectrum Ab (Ticarcillin-clavulanate)
  4. Surgery
29
Q

PE findings in Boerhaave syndrome

A
  1. Crepitus on chest wall palpation
  2. Mediastinal crunching w/ each heartbeat on auscultation (Hamman’s sign - best heard in left lateral decubitus position)

Air accumulation –> Subcutaneous & Mediastinal emphysema (Pneumomediastinum)

30
Q

Complications of Alcoholism

A
  1. Mallory-Weiss syndrome
  2. Boerhaave syndrome
  3. Wernicke-Korsakoff syndrome
  4. Esophageal varices
  5. Liver disease
  6. Pancreatitis (acute & chronic)

Withdrawal
1. Delirium tremens
2. Alcoholic hallucinosis

31
Q

34
Q

MRI findings specific to Wernicke encephalopathy & Korsakoff syndrome

A

Mamillary body atrophy

35
Q

Tx of Wernicke encephalopathy

A

IV Thiamine –> Glucose

Thiamine is always given first bc glucose can precipitate Wernicke encephalopathy

36

48
Q

Types of Hiatal hernia

A
  1. Sliding (type 1)
  2. Paraoesophageal (type 2)
49
Q

Sliding hiatal hernia

A

GEJ + Proximal stomach –> Herniation

50

Paraoesophageal hiatal hernia

A

Proximal stomach herniation

51
Q

CFs of Hiatal hernia

A
  1. Asymptomatic
  2. Acid reflux
  3. Chest pain
