[Value and limitations of the gastric secretion function test with 99mTc-pertechnetate]

Area of Science:

• Nuclear medicine
• Gastroenterology
• Diagnostic imaging

Background:

• Investigating functional organic gastropathies requires reliable diagnostic methods.
• Traditional methods like gastric probing can be invasive and poorly tolerated.
• There is a need for non-invasive, well-tolerated tests for gastric function assessment.

Purpose of the Study:

• To describe a novel gastric secretion test utilizing 99mTc-pertechnetate.
• To evaluate the test's utility in diagnosing functional organic gastropathies.
• To assess the test's value in monitoring treatment outcomes.

Main Methods:

• A gastric secretion test was performed using 99mTc-pertechnetate.
• Computerised gamma camera imaging was employed to measure secretion volume.
• Rapid scintigraphy was utilized for intestinal morphology assessment.

Main Results:

• The 99mTc-pertechnetate test is simple and well-tolerated.
• Computerised gamma camera imaging accurately indicated gastric secretion volume.
• Rapid scintigraphy provided valuable intestinal morphology data when other methods failed.

Conclusions:

• The 99mTc-pertechnetate gastric secretion test is a viable alternative to gastric probing.
• The test offers insights into gastric secretion volume and intestinal morphology.
• Its primary value lies in monitoring the efficacy of pharmacological or surgical treatments for gastropathies.
