|January 1, 1986
Summary
For Zollinger-Ellison syndrome diagnosis, initial gastric analysis before secretin infusion testing is more cost-effective. This strategy improves diagnostic value and reduces unnecessary hospitalizations for hypergastrinemia evaluation.
Area of Science:
- Gastroenterology
- Endocrinology
- Health Economics
Background:
- Hypergastrinemia and gastric acid hypersecretion characterize Zollinger-Ellison syndrome.
- Diagnostic strategies for gastrinoma evaluation require careful consideration.
Purpose of the Study:
- To compare the diagnostic and cost-effectiveness of two strategies for evaluating hypergastrinemia in suspected gastrinoma patients.
- To determine the optimal sequence of diagnostic tests.
Main Methods:
- Decision and cost-effectiveness analyses were utilized.
- Comparison of initial gastric analysis followed by secretin infusion test versus secretin infusion test alone.
- Evaluation of patients with suspected gastrinoma and elevated serum gastrin.
Main Results:
- 59% of patients with elevated gastrin exhibited hypochlorhydria or achlorhydria.
- Gastric analysis followed by secretin infusion test showed superior expected value.
- Outpatient gastric analysis prior to secretin testing was more financially advantageous.
Conclusions:
- Performing gastric analysis before secretin infusion testing enhances diagnostic value.
- Pre-hospitalization gastric analysis is crucial for cost-effective gastrinoma evaluation.
- This approach minimizes unnecessary medical costs and hospitalizations.
