I still have my port for almost 7 years, although the last time I needed it was for chemo two years ago, which now reminds me I need it flushed. I had some doctors after treatments saying the port could be removed, but after a number of recurrences, blood transfusions, I wasn't on board with that, and so was one of my oncologists.
The port doesn't bother me that much, sometimes the skin is more irritable, but that's about it, but you do have to watch it doesn't get infected since the infection can go septic, and that's one reason the doctors say to remove it, and another reason why they don't like to use it for regular blood work either, and persons accessing it should have port training. If there is sepsis, the port and peg are usually removed in case it's the source, and so was my port in 2009 for that reason, although I vaguely remember, but another was later put in, so it was my 2nd port.
Maybe their keeping the port due to your weight loss? They can do TPN, Total Parenteral Nutrition, through there if needed. That's what I needed in 2009/2010 when I lost over 110lbs, and was NPO, even after a peg tube was put in the port was still used to get nutrients in I guess due to the stomach not being a viable.
As far as the peg tube removal, it may depend on the type you have. My first may have been the balloon type, and that was deflated, and yanked out by the gastroenterologist in the office. My 2nd peg, may have been the button type, and that was taken out under sedation during an endoscopy through my mouth in the OR type room where they do these procedures.
You can ask your doctor why it's not being removed. Good luck
