[Algorithm for the diagnosis of small intestinal disease]

Area of Science:

• Gastroenterology
• Medical Diagnostics
• Endoscopy

Context:

• Small intestinal diseases present diagnostic challenges.
• Accurate diagnosis is crucial for effective patient management.
• Current diagnostic algorithms require refinement for optimal outcomes.

Purpose:

• To describe a diagnostic algorithm for small intestinal diseases.
• To guide the selection of appropriate diagnostic tools based on clinical presentation.
• To improve the efficiency and accuracy of small intestinal disease diagnosis.

Summary:

• For massive small intestinal bleeding, prioritize angiography or double balloon endoscopy with vital sign monitoring.
• For mild to moderate bleeding, initiate capsule endoscopy, followed by double balloon endoscopy if needed.
• Suspected small intestinal strictures warrant initial small intestinal radiography, potentially with imaging like CT; abdominal symptoms or occult blood without overt bleeding also begin with radiography.

Impact:

• Provides a clear decision-making framework for clinicians.
• Aims to reduce diagnostic delays and improve patient outcomes.
• Facilitates the appropriate use of advanced diagnostic technologies.
