Gastroenterology/ENT: Clinical Approach to Dysphagia
High-Yield Revision for NEET PG
1. Classification: Oropharyngeal vs. Esophageal
| Feature | Oropharyngeal (Transfer) | Esophageal (Transport) |
|---|---|---|
| Symptoms | Coughing, choking, and nasal regurgitation. | “Sticking” sensation in chest/sternum. |
| Causes | Neurological (Stroke, Parkinson’s). | Structural (Stricture, Cancer) or Motility (Achalasia). |
2. Distinguishing Structural vs. Motility Disorders
- Structural (Mechanical): Dysphagia primarily for solids (e.g., Peptic stricture, Esophageal cancer).
- Motility Disorders: Dysphagia for both solids and liquids from the onset (e.g., Achalasia, Scleroderma).
3. NEET PG High-Yield Pearls
- Achalasia Cardia: Classic “Bird’s beak” appearance on Barium swallow. Due to the loss of ganglion cells in the Auerbach’s plexus.
- Esophageal Cancer: Progressive dysphagia + significant weight loss = Red Flag. Gold standard diagnosis: Endoscopy + Biopsy.
- Zenker’s Diverticulum: A pulsion diverticulum causing halitosis and regurgitation. Avoid blind Ryle’s tube insertion (risk of perforation).
- Diagnostic Sequence: Barium swallow is often the initial investigation for structural evaluation, followed by endoscopy.
