Six days is a long time. I would definitely help it along. I'm almost 6 weeks out from surgery and I don't go poo near as much as I did before surgery. Maybe every 2 or 3 days now. I was concerned because I used to go 2 to 3 times a day! Really though, we're eating so much less. There is a lot less to get rid of and your body is making the most of what out does get.
Congrats on your surgery!
