I understand that certain surgeries can be very technical and require a lot of skill and even a couple of hours, but I don’t understand what would make a surgery last upwards of 5 hours. That seems like a lot of time for cutting someone open and fixing them up.

It’s like a car mechanic, €20 to change a bulb, thousands to change a camshaft or so. The deeper (or more complex) the mechanic/surgeon has to go, the longer it takes. Sounds dumb but same principle.
I would imagine, doing a repair or transplant would take a lot of time because repairing all the veins and capillaries would be tiring. Imagine having to fit together hundreds of tiny tubes and ensure there are no leaks. Also, with a transplant, you’d have to cut all the arteries and bind them so they wouldn’t leak while removing the organ, and then untie and reattach them afterwards.
The more complex the surgery the longer it takes.
Sewing blood vessels, repairs, transplants, screwing pins into bones, it’s all delicate and precise work.
Cutting open a human in a hurry would be like butchering a cow. If it’s already dead it doesn’t matter, but for something alive you would casue a lot of unnecessary damage and probable death.
It’s an estimation. There’s a lot of complexity and prep involved in any surgery and a long checklist to be sure everything is done effectively and in the right order. I mean just search for a step by step process for a surgery and you’ll see. They have teaching videos for specific surgeries on YouTube, many of which are full length. Much more than just cut and sew
Why does your mechanic need a couple days to fix the engine you burned out. It’s just really complicated and humans are wayyyyy more complicated so of course some surgeries can take a long time. Some upwards of 32 hours btw
