Kathy,
Please don't be scared
You really are on your way to getting this nasty thing sorted once & for all - honestly.
Everybody has some anxiety over their surgery - that's normal but a few months after it's done, you will be SO happy you had it done.
You really don't need to make a big deal out of the procedure. Continue to eat and drink normally & use your stool softener to keep your stools nice and soft right up to the time when you are advised you need to stop in preparation for the op. This is just to ensure your stomach is completely empty once given the general anaesthetic and to ensure you are not sick because of it. You will have an examination to determine whether a seton is needed or not whilst asleep because it is the only way your CRS will be able to determine the course of surgery once they are able to get a really good look inside your bottom.
If they decide you do not need the seton, they will more than likely simply "deroof" the fistula tract to drain it & allow it to heal from the inside out. If you need a seton, it will be placed into the tract to allow the fistula to drain fully by keeping it open and you will be fully advised on your outcome afterwards and whether further action will be required or not. A seton is generally placed if the fistula interacts with your internal sphincter muscle and although, some people feel some discomfort in initially getting used to them being there, it will only help in the healing of the fistula. Both procedures are very straightforward and take around 20 minutes!........
You will feel whoozy when you come round after the GA, you might be a bit disorientated and you certainly can't drive, so arrange a lift! Hopefully, you will feel less pain for a few hours, maybe the whole day after, because of the anaesthetic. They generally also use a local in the area too.
Your greatest fear will be your first BM, - I had no issues with this, although I had all the fears!. I ate a full meal straight after my morning op because I was starving & a light meal in the evening (chunky vegetable soup & wholemeal toast) & drank lots of fluids. I basically resumed my normal pattern straightaway but ensured I rested too and put my feet up for a couple of days after. My first BM was nice & soft and was not a problem.
Day 2 I felt more discomfort as the GA wore off, but not enough to warrant pain killers even. If you are in more pain or uncomfortable, take Ibruprofen as soon as you get up to get on top of that pain and not when you start to feel it.
Of course, the first week or two is uncomfortable, not particularly painful but that's normal stuff....
You will probably have some bleeding for a day or two, maybe a little longer but this is normal too and I'd recommend just using a light pad to deal with that. Depending on the fistula, you may have little or a lot of pus discharge as it drains - again this is totally normal and it could take anything between a few days to a few weeks for this to completely clear out.
In the meantime, just keep nice and clean with regular baths/ sitz baths - I always used a shower head because I felt really clean after using this, also the pressure from the water on that area, "stretched" the wound a little, which your CRS may recommend you do to promote proper healing. Don't apply anything externally (creams etc.) on the wound area as it heals because you don't want to risk infection. It needs to remain clean & dry - A gauze or pad may make you feel better if you are continuing to discharge pus still........
As the weeks progress, you will start to feel better and better. I would recommend taking 2 weeks off work, more than anything so you can deal with cleaning-up and tending to the wound. I went back to work 8 days after my op because I felt well enough to do so and I could drive OK.
My fistula took 2 months to heal externally (so I could no longer see the wound) and at about 6 months, I could feel nothing from the area. Any internal aches etc. had disappeared. It was completely gone. Now I would never have known I had one!!
Fistula recovery is generally very straightforward and complete recovery highly successful, so be positive! You will get through it all.......
For the first couple of weeks after the surgery, just focus on
soft BM's so as not to put any additional pressure on the wound, drink lots and rest! Hot baths are relaxing too....If you've any fears,
always chat to your GP for constant reassurance or call your CRS........
Someone will always be here I'm sure to help you with any more questions and mentally support you through the process! Wishing you all the very best and hoping everything goes well for you. Keep us updated!! :)
