Has anyone encountered parasites which look like sticks?

I've found a couple during various enemas ... they are approximately 2 inches long, perhaps 2-3 millimeters in thickness like the thickness of a matchstick, beige colored. It looks like the consistency of ginger, with slight almost imperceptible legs/tendrils. They don't look "rolled up" like the pictures of liver flukes I've seen.

Any idea what they might be?
