Well I haven't traveled by car right after surgery, I did travel by air 10 days after a total colectomy, and as soon as 3 days after other surgeries.

All of my post-surgical travels were without incident, even though I didn't know to get up and wal (this was the 1980s).

I would suggest that you make sure you are very comfortable doing ostomy appliance changes, and have enough appliances on hand. Also ensure that your pain is under control and you have adequate medication on hand.

It sounds like you have a good plan to get up and walk every few hours. Are you having any other surgery done in conjunction with the sigmoidectomy? Will you be having your anus removed?
