For a more precise answer to your question...
Unless there is an infection, or a release of gastric/intestinal contents into the abdomen, people don't "stink" when you cut them open. If there is, yeah, they stink. Infections are by far worse than the smell of crap.
There is, however, a distinct smell to guts. If you've ever dressed a deer, where there is no injury to the stomach or intestines, that's it. It doesn't smell "bad", just different. Fresh blood also gives off a scent, sort of like a very faint scent of bleach, but isn't noticeable unless you have a fair amount.
