@AnKing-Maintainers updated card per Amboss guidelines. Current card is not correct
I would leave tagged RBC scan in extra potentially, have seen it clinically for difficult-to-catch bleeds
Added
Bump
@AnKing-Maintainers please consider voting, or suggestions to improve
Just finished MKSAP GI block, relevant questions agree. On the topic of lower GI bleeding…
“CTA is the initial diagnostic test in patients who are hemodynamically unstable or have rapid ongoing bleeding, followed by immediate upper endoscopy if CTA does not reveal a source of bleeding… although tagged red cell scintigraphy can detect bleeding rates as low as 0.1 mL/min, its usefulness in acute lower gastrointestinal bleeding is debated. Sensitivity of nuclear studies for the detection of a lower gastrointestinal bleeding site varies from 60% to 93%. Although nuclear studies may be able to detect lower gastrointestinal bleeding, precise anatomic location is inferior to that provided by first-line diagnostic tests. Tagged red cell scintigraphy may be considered when results of first-line tests, such as CTA, angiography, or colonoscopy, are negative.”
I like it, feel free to edit it into suggestion, would just try and add an asterix or something to make a note that CTA can be used if EGD/Colonoscopy is inconclusive
I am working on an image for this too in a flowchart style based on AMBOSS. I just need to start looking through uworld questions too and make sure it matches both
sounds good, would like to push this soon as the card is currently incorrect
Agree. I updated the date in Extra to Feb 2025 and fixed a capitalization error
AMBOSS doesn’t have any info on this part in their flowchart for LGIB. They say after CTA do colonoscopy. doesn’t have EGD
@Anking-Maintainers
Can we push this one please? even if it’s not the perfect change but still better than the original
