Small bowel tumors are the most frequent cause of obscure gastrointestinal bleeding in individuals under 50. Small bowel enteroscopy can diagnose these tumors, even when other tests fail.
Area of Science:
- Gastroenterology
- Endoscopy
- Oncology
Background:
- Obscure gastrointestinal bleeding (OGIB) presents a diagnostic challenge.
- Small bowel tumors are a potential cause of OGIB but can be difficult to detect.
Purpose of the Study:
- To determine the diagnostic yield of small bowel enteroscopy for obscure gastrointestinal bleeding.
- To identify the prevalence and characteristics of small bowel tumors in patients with OGIB.
Main Methods:
- Small bowel enteroscopy was performed on 258 patients with OGIB.
- Previous diagnostic evaluations including enteroclysis and angiography were reviewed.
Main Results:
- Small bowel tumors were diagnosed in 5% of patients.
- In patients under 50 years old, small bowel tumors were the most common cause of OGIB when a diagnosis was established.
- No diagnosis was made in 50% of patients.
Conclusions:
- Small bowel tumors are a significant cause of OGIB, particularly in patients under 50.
- Small bowel enteroscopy is a valuable tool for diagnosing small bowel tumors in cases of OGIB, even after negative conventional investigations.
