Question 46

The most accurate diagnostic test for Gastroesophageal Reflux Disease is

Answer 46

1-24-hour pH monitor, an electrode is placed several centimeters above the gastroesophageal junction, and a determination is made of what the average pH is in that area.

Question 47

What is the order when working up GERD

Answer 47

• Initiate PPI; if no improvement, increase PPI to 2x daily (before EGD) for 4–8 weeks and make sure patient is taking properly (30–60 min before meals) • If no improvement, do EGD: If EGD shows esophagitis, that confirms GERD and 24-hour pH monitoring is not needed. If EGD is normal, do ambulatory 24-hour pH monitoring (while off the PPI) and if results are consistent with GERD, do Nissen fundoplication.

Question 48

In clear cases of epigastric pain going under the sternum and associated with a respiratory complaint or bad taste in the mouth, do the following

Answer 48

initiate therapy immediately with antisecretory medications such as PPIs.
