i have stage 4 started in Colin and went to the liver, It came to the point i was totally blocked, so they put stents (total of 3), since it went to liver they wanted me on chemo prior to doing the Colin surgery. But once they removed about 6 " of Colin(9 months of chemo prior), the hardest part on the recovery was all the gasses built up from surgery. Once that ended I never had a problem or any symptoms of pain at all. It was nice to finally have a normal Colin back. Now i'm back on chemo with Liver issue and new nodules
Good luck 👍 with your results.
