Outcome in obscure gastrointestinal bleeding after capsule endoscopy.

Area of Science:

• Gastroenterology
• Diagnostic Endoscopy

Background:

• Obscure gastrointestinal bleeding (OGIB) presents diagnostic challenges.
• Capsule endoscopy (CE) is a valuable tool for investigating OGIB.

Purpose of the Study:

• To evaluate the clinical impact of capsule endoscopy (CE) in obscure gastrointestinal bleeding (OGIB).
• To identify diagnostic work-up, follow-up strategies, and predictive factors for rebleeding after CE.

Main Methods:

• Retrospective analysis of 105 patients with OGIB who underwent CE.
• Data collected included demographics, medications, hemoglobin levels, CE findings, and outcomes.
• Statistical analysis involved chi-squared tests, Student t-tests, and Cox regression for rebleeding risk factors.

Main Results:

• CE diagnostic yield was 58.1% for OGIB.
• Rebleeding occurred in one-third of patients.
• Independent predictors of rebleeding were hemoglobin < 8 g/dL, age ≥ 70 years, and significant CE findings.

Conclusions:

• Capsule endoscopy is effective in diagnosing OGIB.
• Hemoglobin levels, age, and CE findings predict rebleeding risk.
• These factors can inform clinical management and follow-up strategies for OGIB patients.
