If someone has had subtotal colectomy w/ileostomy placement, can a partial colectomy be performed later on down the road? and what's the difference?

Big difference : A subtotal colectomy is removing almost all the colon; usually just a couple of inches are left near the rectum. A partial colectomy is not done AFTER a subtotal colectomy because there is basically no colon left. A partial colectomy implies that only a segment of colon is removed, like the right or left, and a good amount of colon is left.
