The first resection I had was one of the best moments of my life, starting the very next day despite being sick from nil by mouth and drugs because a year of pain was finally over and I actually slept through a whole night. The recovery was also surprisingly fast, I was home in a week and able to eat normally etc. That was 26 years ago and the surgery and repair techniques have improved greatly since then.
The advice I would give is make sure you know what area they are working on, as it may have knock on effects for the future such as changes to digestion. I can't recommend or not because I'm not a doctor and I don't know the specifics of your case, but if your doctor/surgeon feels it is the best treatment there are probably good reasons.
