Insights
This article presents an algorithm for diagnosing small intestinal diseases. It outlines diagnostic strategies for various bleeding severities and suspected strictures, guiding clinicians toward appropriate endoscopic and imaging techniques.
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.
Abstract:
This article describes algorithm for the diagnosis of small intestinal disease. In case of massive small intestinal bleeding, angiography or double balloon endoscopy should be done firstly under the observation of vital sign and general condition. On the other hand, we have to select capsule endoscopy as a first-line examination in patients with mild or moderate small intestinal bleeding, and thereafter, double balloon endoscopy would be done for the decision of the diagnosis. If the patients are suspected of having stricture of the small intestine, they will initially undergo small intestinal radiography associated with or without abdominal ultrasonography and computed tomography. In addition, small intestinal radiography will be performed as a first-line examination in patients having abdominal symptom or occult blood stool without overt gastrointestinal bleeding, and as a subsequent examination, double balloon endoscopy and capsule endoscopy may be done.
