High Yield Gastrointestinal Review for Step 1/Step 2 CK and Shelf Exams

This is a high-yield gastrointestinal review for the shelf exams and Step 2 CK. Everything in this video is centered around practice questions, and then we work through each concept and how it can be highly tested. With the updates to Step 2 CK including more pathophysiology, much of the information in this video is highly applicable for Step 1 as well.

Note: The age demographic for primary sclerosing cholangitis (PSC) is predominantly male unless in the absence of IBD (in which case it is female). So disregard the bullet point under PSC towards the end of the video regarding the gender demographic. I try to clarify this in the video but wanted to make a permanent mention of the differences between PBC and PSC. PBC classically occurs in middle aged females on USMLE exams, which is something that is very important to know. The downloadable slides on the website will be updated so this will hopefully be less confusing when reviewing in the future.
Additional point: When referring to the highly tested anatomical GI landmarks (specifically the rectosigmoid junction), the important point was to differentiate which pathology occurs at each landmark. It was not to imply that acute colonic ischemia at watershed distributions was another form of obstruction; it will usually present in the setting of severe hypovolemia/hemorrhage/ischemia. Thinking of the GI tract as a system that has separate entities occurring depending on the anatomical features and remembering these presentations is what's important. So just remember these landmarks as important sites where they like to test very specific pathology but don't think that each of them has to present as an obstruction.

Thank you so much Dr. Tim! The videos are spot on and very useful. You are very smart! Can you do more on gastro?

Great suggestion, I can definitely try to prioritize more GI in the future!
