Colonoscopy in lower gastro-intestinal haemorrhage
Summary
Colonoscopy significantly improves diagnosis and management of lower gastrointestinal bleeding when standard investigations are inconclusive. This study highlights its value in identifying lesions and performing polypectomy in 107 patients.
Area of Science:
- Gastroenterology
- Endoscopy
Background:
- Lower gastrointestinal hemorrhage diagnosis can be challenging with standard investigations.
- Colonoscopy offers a direct visualization method for the lower gastrointestinal tract.
Purpose of the Study:
- To evaluate the diagnostic and management utility of colonoscopy for lower gastrointestinal hemorrhage.
- To assess colonoscopy's role in cases with uncertain radiological findings or normal barium studies.
Main Methods:
- A retrospective analysis of 107 patients undergoing colonoscopy for lower gastrointestinal bleeding over a 2-year period.
- Comparison of colonoscopy findings with previous radiological and sigmoidoscopy results.
Main Results:
- Colonoscopy confirmed, defined, or refuted radiological findings in a significant number of patients.
- Twenty-eight previously undiagnosed lesions were identified by colonoscopy.
- Colonoscopy achieved a diagnosis in over two-thirds of patients with frank bleeding and normal radiographs, but was less effective for occult bleeding.
- Polypectomy was performed in 30 patients, with 37 polyps removed.
Conclusions:
- Colonoscopy significantly enhances the diagnosis and management of lower gastrointestinal bleeding, particularly when initial investigations are inconclusive.
- It is a valuable tool for identifying lesions and therapeutic interventions like polypectomy.
