Yup I definitely know what you mean about the Fleet enema. Using that thing SUCKED when the anal area was already in pain. The first few moments after it started working where I pooped out the fluid were just terrible. I told the nurse when I was admitted that my pain level was around a 5, but after I used the enema, I asked her to change it to a 9 lol.
Lemme guess: your husband called in for the wrong Rx? Hey watch the men comment now, some of us actually pay a lot of attention to detail and even correct doctors on compound drug concentrations haha :) Maybe a short course of hydrocortisone would help your irritation? I know it's not supposed to be used long term because it thins the anoderm but it's alright for short term (like a few days use) to put down inflammation/irritation right? I know nitroglycerin is used for various butt problems, including hemorrhoids, so maybe it'll work just as well I guess? Whatever it is, I hope it gets sorted out soon. After my own adventures, I'm all about being proactive when it comes to butt problems now lol.
BTW since you are the butt expert

I wanted to run something by you (long message warning!). For my procedure today the paperwork says "incision and drainage with fistulotomy of perianal abscess." I remember reading before I went in that about 50% of all perianal abscesses result in a fistula, so I made sure to ask the doc before surgery what the fistulotomy part meant and whether she was doing it for sure. My memory of her response is fuzzy because the anesthesia kicked in a few minutes later, but I think she said that she put it there just in case she found a fistula after cutting the abscess open. So I said okay, that sounds fine. Honestly at that point I just wanted the whole thing over with and didn't care what it took, if it can help me in the long term, I'm doing it!
But being the obsessive person that I am, I searched for more info after I got home, but there wasn't a whole lot of very directly pertinent information. I did find this in the Wikipedia article on LIS however:
---------------
Perianal abscess occurs in about 1% of closed sphincterotomies, generally in association with anal fistula caused by a breach of the anal mucosa by the scalpel. Incision and drainage of the abscess and fistulotomy are required.
---------------
I also searched for fistulotomy on this board and saw a few previous threads on it related to abscesses.
The best I can figure is that in some cases, the abscess "bump" conceals a tunnel that goes through to the other side of the anal wall, and the only way to tell if that's the case is to cut the bump open and look (or probe with a special tool) once the pus is out of the way. If there's a fistula, then you do the fistulotomy. If there isn't then you simply leave the bump open. Does that sound right?
This is mostly for my curiosity. I forgot to ask the doc if she actually did the fistulotomy, but I don't think she did. I was really hazy from the anesthesia after the surgery, but I think I recall her saying that when she opened the abscess, some of the pus had already drained out from earlier, and all she did was cut it open wide to make sure everything was out.
Then again, in the worst case I guess it's possible that she did do the fistulotomy, and that's why I pooped myself a couple of times after surgery :( I still think that one is due to the anal trauma and loose stools caused by the enema though...
I'll have to double check when I have my follow up appointment in a few weeks. But if you have ideas on what "incision and drainage with fistulotomy of perianal abscess" means in the context of an abscess after LIS means, I'd be most interested. For now I just hope this takes care of whatever the hell the problem was.
