One-liner

This episode provides a comprehensive review of esophageal pathology, covering the workup and management of motility disorders like Achalasia and Diffuse Esophageal Spasm (DES), differentiating perforation syndromes (Boerhaave vs. Mallory-Weiss), understanding GERD progression to Barrett's esophagus, and reviewing complications of portal hypertension.

High-yield summary

• Esophageal Perforation: Boerhaave syndrome is a transmural, often unstable rupture usually associated with forceful vomiting/retching; Mallory-Weiss tear is a partial thickness, longitudinal mucosal tear typically caused by severe retching following alcohol consumption, and the patient remains hemodynamically stable.
• Achalasia Workup: The classic triad includes dysphagia to solids and liquids, Barium swallow showing a "bird's beak" appearance (dilated esophagus with distal narrowing), and manometry demonstrating high LES pressure and absent/diminished peristalsis.
• GERD Progression: Chronic GERD leads to Barrett's esophagus, which is defined as intestinal metaplasia of the esophageal lining (non-keratinized stratified squamous epithelium replaced by columnar epithelium with goblet cells). This significantly increases the risk of adenocarcinoma.
• Motility Disorder Differentiation: Diffuse Esophageal Spasm (DES) can mimic Achalasia but is differentiated on manometry by having normal LES pressure and uncoordinated, simultaneous contractions, whereas Achalasia has high LES pressure and absent peristalsis.
• Esophagitis Etiologies: When performing EGD for esophagitis, specific findings point to the cause: Candida (opportunistic), HSV (punched-out ulcers), CMV (linear ulcers).
• Portal Hypertension: Acute hematemesis with signs of shock/hypotension in a patient with cirrhosis strongly suggests an esophageal variceal bleed. Management requires fluids, blood products, EGD, and prophylactic beta-blockers.

Learning objectives

• Differentiate between Boerhaave syndrome and Mallory-Weiss tears based on clinical stability and depth of injury.
• Interpret Barium swallow findings for Achalasia ("bird's beak") versus other strictures.
• Understand the pathophysiology, progression, and surveillance of GERD leading to Barrett's esophagus.
• Master the diagnostic workup (Barium swallow, Manometry) required to distinguish between various esophageal motility disorders.
• Recognize the signs and immediate management steps for acute esophageal variceal bleeding secondary to portal hypertension.

Management pearls

• Achalasia Workup: The gold standard initial study is the Barium swallow, looking for the "bird's beak" sign. Manometry confirms high LES pressure and absent peristalsis.
• GERD Management: Initial treatment involves a 6-week trial of PPI therapy; if symptoms persist, EGD and monitoring are required to rule out strictures or Barrett's esophagus.
• Boerhaave Syndrome Management: This is a surgical emergency requiring immediate resuscitation (IV fluids, blood) due to the high risk of mediastinitis and sepsis.
• Variceal Bleeding Management: Initial steps include AB Cs (Airway, Breathing, Circulation), IV fluids, blood transfusion, EGD with band ligation, and prophylactic beta-blockers.

Integration & clinical reasoning

• GI/Endocrine: Chronic acid exposure (GERD) can lead to Barrett's esophagus and increased cancer risk; this process is often exacerbated by factors like obesity or smoking.
• Vascular/Hepatology: Portal hypertension leads to esophageal varices, which are a direct complication of advanced liver disease (cirrhosis). Bleeding requires immediate recognition and aggressive management.
• GI/Infectious Disease: Esophagitis must be treated empirically based on the patient's immune status; specific ulcer morphology (punched vs. linear) helps narrow the differential diagnosis for viral causes.

OMM / COMLEX integration

• For acute esophageal perforation (Boerhaave syndrome), standard emergency management (resuscitation, surgical intervention) takes absolute priority over OMT.
• In the context of chronic GI issues like GERD/Barrett's, understanding visceral innervation and local inflammation can be integrated into holistic care plans, but this is not an acute OMM focus.

Question pattern recognition

• Dysphagia to solids AND liquids: Strongly suggests a primary motility disorder (e.g., Achalasia, Scleroderma), rather than a mechanical obstruction (which usually only affects solids first).
• Unstable patient with hematemesis/mediastinum findings: Always suspect Boerhaave syndrome over Mallory-Weiss tear; the instability is key.
• Chronic GERD + Goblet Cells on Biopsy: This combination points directly to Barrett's esophagus, which mandates surveillance endoscopy due to cancer risk.
