What diagnostic test can be performed during an endoscopy to analyze gastric secretions?

• A. Ultrasound imaging
• B. pH monitoring
• C. Barium swallow study
• D. CT scan

Answer: (B)

The diagnostic test that can be performed during an endoscopy to analyze gastric secretions is pH monitoring. This procedure specifically measures the acidity levels within the stomach or esophagus, providing valuable information about gastric secretions. During an endoscopy, a small probe can be placed to continuously monitor and record pH levels over a period, which can help assess conditions such as gastroesophageal reflux disease (GERD) or other acid-related disorders. This technique is particularly relevant because it allows for real-time analysis while the endoscopy is being conducted, establishing a clear link between the patient's symptoms and their gastric secretions. It is a direct, effective method that gastrointestinal specialists often use when evaluating the efficacy of acid suppression therapies or determining the underlying causes of gastritis or esophagitis. Other diagnostic tests such as ultrasound imaging, barium swallow studies, and CT scans serve different purposes and are generally not conducted during an endoscopic procedure. Ultrasound is typically used for assessing soft tissue structures, barium swallow studies involve the patient ingesting a contrast material to visualize the esophagus and swallowing function, and CT scans provide cross-sectional imaging for assessing a broader range of conditions, but do not analyze gastric secretions directly.
