Summary
Endoscopy aids in diagnosing celiac disease (CD) by identifying specific endoscopic markers and villous atrophy. However, random duodenal biopsies are crucial, as normal-appearing mucosa does not rule out CD.
Area of Science:
- Gastroenterology
- Digestive Diseases
Background:
- Celiac disease (CD) is an autoimmune disorder triggered by gluten ingestion.
- Accurate diagnosis is essential for effective management and preventing complications.
Purpose of the Study:
- To review the current evidence on the utility of endoscopy in diagnosing celiac disease.
- To highlight the role of endoscopic findings and biopsy techniques.
Main Methods:
- Review of existing literature on endoscopic diagnosis of celiac disease.
- Discussion of various endoscopic modalities including magnification endoscopy, chromoendoscopy, and video capsule endoscopy.
- Emphasis on duodenal biopsy strategies.
Main Results:
- Endoscopic markers for celiac disease are specific but not sensitive.
- Villous atrophy, a key feature, can be patchy in the duodenum.
- Advanced endoscopic techniques and video capsule endoscopy show promise for diagnosis and assessing complications.
Conclusions:
- Endoscopy and duodenal biopsies are fundamental for celiac disease diagnosis.
- Characteristic endoscopic findings are helpful but not definitive.
- Random biopsies of even normal-appearing mucosa are necessary to exclude celiac disease.
