I had a gastric tube put in twice for pouch surgeries (once for a month & the other for 2 weeks) but came out without any problem...sort of felt like the 'drop' in the roller coaster when it came out but didn't hurt (it was sutured in to my stomach so the sutures hurt more than the tube removal...they were red and swollen).
I was very acidy so there was a bit of green acid burn when it was pulled but it healed beautifully.
No complications
