Read this during med school during my surgery rotation but its pretty long and if you want to be more quick for your exams then I suggest online or class resources (medbullets, uworld, uptodate, lectures, shorter versions of surgery textbooks).
If you’re sitting for your boards/steps— I suggest stick to uworld, pathoma, osmosis/kaplan videos, usmleRx, and the trusty First Aid for the respective steps!
I read most of GI surgeries from this thoroughly for my OR rotations. I found them much easier to understand and digest. I think this is a great resource at a junior level but only for topics you find tough.
