Foul smelling wind

Hello all

I was lucky enough to have my over 50s stool sample pick up an issue 2 and a half years ago, I quickly had a colonoscopy and they found a pollop which was removed and sent away for examination and I was to get results within 6-8 weeks, I never heard anything in that time and presumed all was ok. It was about another 3 weeks after I had a phone call to say that they were sorry about the delay but my pollop had been sent to many different places for examination as it was unusual but undead cancerous. I was advised to have my sigmoid colon removed to which I agreed, unfortunately when they removed the pollop they didn't mark where it came from( apparently they are supposed to mark with a wee tattoo to show it's whereabouts) so I had to have a sigmoidoscopy to try and locate scarring evidence but they couldn't find it. Anyway I went in had the op and they removed more than they expected too from rectum to top of descending colon.

Anyway a would say I have now fully recovered and tests are ok, still have a few CT scans etc to go but my problem is the very foul smelling wind, is this normal? It is very embarrassing for me and I will only go in a public loo if nobody else in there, my long suffering wife puts up with it but will sometimes sleep in the spare room because of the smell, I have tried different foods but nothing really seems to help. Any help greatly appreciated.
