hello greetings from Perú, thanks for this very usefull video, i would like to ask about keyboard sign for SBO is that important as the other signs?
As far as I know, they keyboard sign is just the villi in the intestine. Not necessarily an abnormal finding to see those. I would focus in on the direction of peristalsis and the diameter/non collapsibility of the lumen.
Thanks for this great video. I have one question: is ultrasound good at differentiating ileus from mechanical obstruction, or can you not tell? Love your ultrasound tutorials!
There probably are some subtle findings, but for the most part, US isn’t super reliable at finding a transition point (which is what would be the gold medal way to tell the difference)
