it isnt what you are thinking. placing a gastrostomy tube is barely surgery. Compared to the dissection you underwent, a gastrostomy tube placement is a very pleasant walk in the park on the nicest day of the year with the sun shining and the birds singing.
The mediport placement is on a par with the gastrostomy tube placement. Some would argue the gastrostomy tube placement is somewhat easier even than the mediport placement. These two surgeries are arguably not even surgery.
The gastrostomy tube is so easy, even non-surgeons such as gastroenterologists and radiologists with the training to do it are allowed to do it, which they do all the time. Same for mediports which are routinely placed by interventional radiologists, much to the dismay of the surgeons who are constantly losing business to all these other specialties.
I am not saying there is no risk - walking across the street carries some degree of risk of getting hit by a car. If the person doing the procedure is not experienced or having a bad day or did not get enough sleep there are all sorts of bad things that can happen from puncturing a lung to peritonitis. What I am trying to say is that if you are reluctant to have it done because you have bad memories of the dissection you underwent, don't be. They are like apples and oranges. Speaking of apples and oranges, you need to get that g-tube so you don't get down to 75 pounds with malnutrition and then die of some small infection because you were too malnourished to fight it.
You've come this far. Be Strong, it will be ok,
