Qayonna 1 Posted September 15, 2015 how long is the procedure? Share this post Link to post Share on other sites
soatlast 16 Posted September 15, 2015 I believe the average rny bypass surgery is 1 hour 15 minutes to 1 hour 30 minutes. Of course that is dependent upon the surgeon and any issues they may run into (scar tissue, fat around the liver, etc). My surgeon told me it would take him about 1 1/2 hours during my last pre-op appointment, which was about 10 days out from my surgery date. Have you gone to see a surgeon yet? Do you have a surgery date? Welcome to the boards Share this post Link to post Share on other sites
