I finally found a good discussion on the Nissen fundoplication surgery - for children. Most of what I had read was relating to the surgery in adults.
So, we're dealing with several issues. The G-tube surgery has a relatively easy recovery as compared to the Nissen. The hospital stay would be much shorter. Less time in the hospital cuts our chances of getting an infection (staph, RSV, etc.). It also would be less time under anesthesia.
It would be ideal to do either or both surgeries while Oliver is still pretty healthy. Once his health declines or his breathing becomes more difficult, the whole anesthesia intubation/extubation monster rears its ugly head.
If we don't do the Nissen now, we pray that he doesn't have problems with reflux. Unfortunately, reflux is one of the major side effects of feeding via G-tube. Even if there have been no indications of reflux prior to the surgey. (Oliver's gastric emptying study only revealed one minor incidence of reflux just after starting the study. He has only spit-up 3 or 4 times - total - in his 6 months of life.)
If there is reflux, we could risk doing the Nissen surgery later or the tube into the stomach could be lengthened so that it empties into his intestines. Lengthening the tube means that his stomach would be bypassed and he would always feel hungry. Plus, if the tube goes into the intestines, you have to do continuous feeds. Bolus feeds are not an option. (Bolus feeds are feeds that are done 4 to 8 times a day for 15 to 30 minutes each time. This is more like a normal bottle-feeding schedule.)
As you can see, this is a complicated decision-making process.
We are leaning towards doing both the G-tube and the Nissen fundoplication. And doing it fairly soon. I would like to get all of his doctors together before the surgery to make sure that we are all in agreement on how to best handle Oliver's care. (I don't want to have to argue the pros or cons once we're in the hospital and have had the surgery.) I hope to do a little bit of educating with some of the info that I've found relating to these procedures in children with SMA. I'd love to get some of the standard of care guide information into his chart so that every doctor or nurse can easily reference it.
There is one other "fun" aspect of this process. One that we haven't really touched upon yet - the insurance company. I'm not looking forward to that battle.
