Use of CO2 Angiography in the Identification of the Bleeding Source of Colonic Diverticular Hemorrhage: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Diverticular hemorrhage is the most common cause of lower gastrointestinal bleeding (LGIB). Because spontaneous hemostasis frequently occurs, identifying the bleeding diverticulum via colonoscopy or iodinated contrast angiography remains challenging. Recently, several reports have demonstrated the utility of CO2 angiography in identifying the bleeding source. Case Presentation: The patient was a 73-year-old male referred to our hospital for hematochezia and was ultimately diagnosed with colonic diverticular hemorrhage. Despite repeated massive hemorrhage, spontaneous hemostasis prevented localization of the bleeding site; neither colonoscopy nor conventional iodinated contrast angiography detected the source. Finally, CO2 angiography was performed to successfully identify the bleeding site, which enabled transcatheter arterial embolization to achieve hemostasis. Conclusion: In cases of recurrent diverticular bleeding where the bleeding site remains undetectable, CO2 angiography may be an effective method to identify the source and guide targeted therapy.
