Ok...I've been researching this quite a bit...So skin grafts are different than flaps. Skin grafts are just skin, no fat, no blood vessels...just skin. They require a clean area with a good blood supply to be useful. I have read one case study online of a surgeon who used it successfully on a patient in Pennsylvania. Synthetic skin, or cadaver skin (gross I know), has the similar drawback of not having any blood supply or supportive tissue as is the case in a flap.
Flaps have a fatty vascular cushion of tissue, and can be local or distant, of many different shapes, sizes, and orientations. Plastic surgeons do flaps mostly everywhere so they are good at making them supposedly, albeit not in the anus. I asked both plastic surgeons about a distant flap, like from skin from my leg or belly, and they told me that distant flaps require you disconnecting the tissue from it's blood supply, and then finding a new artery to reconnect using a microscope. They said that is a very extensive procedure, and on a flap this small, it's not worth the effort. I still think it is an option though and am going to research it further if all else fails. There are also flaps called interpolation flaps, where they use skin from near, but not adjacent to the defect, and jump over the unusable skin. This one looks weird, as you literally have a flap of skin hanging and bleeding which is connected at one end to it's donor site, and the other end to the defect. The hope is that new capillaries form to provide blood from the defect, and then the bridge to the donor site is cut in a subsequent surgery. This would be very hard if not impossible in the anus because you couldn't sit on it, let alone poop on it. I'd imagine it would get infected very easily as well.
At my 10 day follow-up my CRS told me the right suture line was open. He said just a tiny bit open, and said it should heal up anyway. I waited till about 5 weeks to decide I better start getting ready for backup plans. That's when I started with the HBOT, and then the Kenalog procedure. I never really knew it wasn't going to heal...I'd just keep going back to his office and he'd keep saying give it a few more weeks...just like last time and the time before. Now it's 3 months since Kenalog, and over six months since the flap. I had a fairly sizable but healthy and smooth poop this morning and I'm still in pain 7 hours later. My butt still bleeds and aches and hurts when I sit in a hard chair. Now I KNOW without a doubt that this wound will not be going away without a surgical intervention, and possibly even with one...
