"some individuals do not do well with any kind of surgery no matter the organ involved"

Yes, I'm one of those people. After the surgery to remove the tumour from my spine, I went through two months of cascading post-surgical complications which kept me confined a critical care bed before I could move to the rehab centre.

Obviously, prostate surgery is much less drastic than spinal surgery, but my first reaction was a prolonged ileus (shutdown of my digestive system) that resulted in IV feeding, a suction tube down my nose into my stomach, 40 lb of weight loss, and temporary diabetes that required insulin injections. That was the first time in my life I went under general anaesthetic, and I will avoid it in the future unless there's no other reasonable choice.
