Question 1
A 42-year-old woman with typical heartburn and regurgitation symptoms for two years undergoes upper endoscopy showing normal esophageal mucosa (Los Angeles grade 0). She is referred for 24-hour ambulatory pH-impedance monitoring performed off proton pump inhibitor (PPI) therapy. According to the Lyon Consensus 2.0, which of the following findings provides conclusive evidence of Gastroesophageal Reflux Disease (GERD)?
Correct Answer:
Total Acid Exposure Time (AET) greater than 6.0% with more than 80 total reflux episodes over 24 hours.
Question 2
A 58-year-old male with a 15-year history of chronic GERD undergoes screening endoscopy. The endoscopist identifies salmon-colored columnar mucosa extending 3 cm circumferentially and reaching a maximal extent of 5 cm above the gastroesophageal junction (Prague C3M5). Biopsies confirm intestinal metaplasia with goblet cells and no dysplasia. According to standard gastroenterology guidelines, what is the appropriate surveillance strategy?
Correct Answer:
Repeat high-definition upper endoscopy with 4-quadrant biopsies every 2 cm (Seattle protocol) in 3 to 5 years.
Question 3
A 35-year-old man presents with progressive dysphagia for both solids and liquids and unprovoked regurgitation. High-Resolution Esophageal Manometry (HRM) reveals an elevated median Integrated Relaxation Pressure (IRP = 28 mmHg, normal < 15 mmHg) and 100% failed peristalsis, with panesophageal pressurization observed in 40% of test swallows. Under the Chicago Classification v4.0, what is the definitive motility diagnosis?
Correct Answer:
Type II Achalasia (Achalasia with panesophageal pressurization).
Question 4
A 26-year-old atopic male presents with intermittent solid-food dysphagia and an episode of food impaction requiring endoscopic meat bolus extraction. Endoscopy reveals circular esophageal rings ('trachealization'), linear furrows, and white exudative plaques. Esophageal mucosal biopsies show 25 eosinophils per high-power field (HPF). What is the first-line management protocol for this patient?
Correct Answer:
High-dose proton pump inhibitor (PPI) therapy or swallowed topical corticosteroids (fluticasone/budesonide) or an empiric food elimination diet.
Question 5
A 62-year-old patient born in a rural area of Minas Gerais, Brazil, presents with a 5-year history of worsening dysphagia, regurgitation, and weight loss. A barium esophagogram demonstrates an esophageal diameter of 6.5 cm with marked distal tapering ('bird-beak' sign), tortuosity, and significant barium retention (Rezende Classification Group III). Serology for Trypanosoma cruzi (ELISA and indirect immunofluorescence) is positive. What is the underlying pathophysiology of Chagasic megaesophagus?
Correct Answer:
Parasite-mediated destruction of the myenteric (Auerbach's) nerve plexus leading to loss of inhibitory nitrergic neurons and aperistalsis.
