mainly the presence of the anus.
The digestive system of flatworms is very simple: food goes into a sac-like gut from the mouth, gets digested, and whatever is left comes back out through the mouth. It rarely has any other organs associated with it .
For roundworms, they have 3 parts to their digestive system: stomodeum (which is stoma and esophagus), mesenteron (intestine), and proctodeum (rectum and anus). You can guess how food travels there

If I remember correctly, flatworms don't have that "tube within a tube" configuration. They are flat so they can absorb nutrients directly through their skin, and they lack a digestive tract.
