Colon cancer spread to small intestine, what do you suggest?

Depends: Did it grow directly into the small bowel or spread as a metastasis? In one or in many places? Was it just diagnosed or is it a late recurrence? Any previous chemo? What's the patient's general health? The patient's oncologist should be able to weigh all the options and come up with a treatment plan. If this is about you, best wishes.
