Use of gastric function tests by British gastroenterologists

Area of Science:

• Gastroenterology
• Clinical Practice

Background:

• Gastric function tests are crucial for diagnosing and managing gastrointestinal disorders.
• Understanding current practices in gastric function testing is essential for improving patient care.

Purpose of the Study:

• To investigate the choice and utilization of gastric function tests among members of the British Society of Gastroenterology.
• To identify trends and potential areas for improvement in the application of these tests.

Main Methods:

• A questionnaire-based survey was administered to members of the British Society of Gastroenterology.
• Data on the selection and application of various gastric function tests were collected and analyzed.

Main Results:

• Pentagastrin is the preferred stimulant for maximal acid secretion, largely replacing older agents.
• Insulin tests are frequently employed in scenarios where their clinical utility is questionable.
• Physicians utilize gastric secretion tests less frequently than surgeons, particularly for uninvestigated dyspepsia or gastric ulcers.
• Surgeons show greater enthusiasm for testing in specific cases, such as post-gastrectomy or vagotomy patients.
• Assessment of vagotomy completeness is inconsistent, with only half of surgeons attempting it, and a third of those doing so routinely.
• Routine acid measurement for duodenal ulcers and to guide surgical decisions is criticized.

Conclusions:

• Current practices in gastric function testing show variability and areas of suboptimal application.
• Pentagastrin is the established stimulant for acid secretion testing.
• The use of insulin tests and routine acid measurements warrants re-evaluation.
• Improved standardization and judicious application of gastric function tests are recommended.
