Insights
Computed tomography (CT) of the abdomen can help locate the source of acute lower gastrointestinal bleeding when endoscopy is inconclusive. This imaging technique identified lesions in 86% of patients with temporarily stopped bleeding.
Area of Science:
- Gastroenterology
- Radiology
- Medical Imaging
Background:
- Acute lower gastrointestinal bleeding presents diagnostic challenges in localizing the bleeding source.
- The utility of computed tomography (CT) in evaluating these patients remains underexplored.
Purpose of the Study:
- To assess the effectiveness of CT abdomen in localizing the source of acute lower gastrointestinal bleeding.
Main Methods:
- A retrospective review of patients with acute lower gastrointestinal bleeding over three years.
- CT abdomen was performed on patients with normal endoscopies and clinically ceased bleeding, after other methods failed.
Main Results:
- CT scans were performed on seven patients.
- A bleeding lesion was identified in six of these patients (86% detection rate).
Conclusions:
- CT abdomen shows promise as a valuable tool for localizing lesions in acute lower gastrointestinal bleeding.
- Its utility is particularly noted when endoscopy fails and bleeding has temporarily subsided.
Objective:
To evaluate the role of CT abdomen in the localization of acute lower gastrointestinal bleeding.
Summary Background Data:
The source of bleed in acute lower gastrointestinal bleeding is often difficult to localize. The role of CT in the evaluation of this group of patients has not been clearly addressed.
Methods:
A retrospective review of all patients with acute lower gastrointestinal bleeding over a 3-year period was carried out. When endoscopy failed to localize the source and bleeding continued, angiography and/or scintigraphy were carried out. In contrast, those who had normal endoscopies and had clinically stopped bleeding, underwent CT abdomen.
Results:
CT done in 7 patients with no evidence of active bleed identified a lesion in 6 (86%).
Conclusions:
CT may be useful in acute lower gastrointestinal bleeding where endoscopy fails to localize a lesion and bleeding has stopped temporarily.
