Seton

When you have a fistula it is likely it will keep producing pus and form one abscess after the other. Draining the abscess is first priority, but what about the fistula? Especially when you have Crohn's, doctor's try to keep you out of the operating room because surgery does more harm than good. With a fistula it's the same. First of all because a fistula is an active infection, secondly because the surgical options are limited. When you have a fistula in ano, it is likely the tunnel tract goes through one or both of your sphincters. Cutting through your sphincter could cause incontinence. So when you're fistula is still active you will probably be treated with medication first to get the infection under control. When this doesn't work enough they will probably suggest to place a seton before taking more extreme meassures such as a fistula surgery, which I will discuss in another post. A fistula surgery is also not a good option when the fistula is still active because it is more likely that the infection will be locked in and eventually cause even more damage.

What is a seton?

A seton is a rubber string/wire/cord that is used for continuously drainage of the fistula. The seton will be placed through the fistula tract and will run in a loop with both ends tight together on the outside of the fistula. Keeping the fistula tract open can help prevent pus and other infections from piling up inside the tract. To place a seton the surgeon must first find the internal opening of the fistula tract. This is where the seton has to run through. The other opening has to be created and will probably be at or nearby the same place where your abscess was drained. 

Two types of seton

There are two types of seton. A loose seton and a cutting seton. The choice between both depends on the placing of the fistula. A low fistula can be treated with a cutting seton. In this case the seton will be tightend every once in a while and will slowly cut out the fistula tract without harming the sphincters. When you have a high fistula this won't work and a loose seton will be placed. Loose doesn't mean that the seton is very loose, it's still tight, but it won't be tightend any further. I've found a very helpfull youtube FILM that explains among other exactly the choice between the two types.

Taking care of the seton

When you have a fistula in ano the seton will run through your butt, through your rectum and will be tight together on the outside near your ano. Because the seton keeps the fistula open, pus can run through all day and night, so you will probably have to use sanitary towels to keep you from leaking. It also makes going to the bathroom a little bit more challenging because of the placing of the seton. Just using toiletpaper isn't enough anymore, you will have to keep it clean by flushing it with water. Either from a bottle or using the shower. When you have a loose seton you also have to make sure to turn it a little from time to time to prevent it from getting stuck. 

For how long?

My surgeon told me my seton would be nescessary for about 3 months. It has now been a year and my seton is still in my butt because the fistula tract is still active. I've read many forums and blogs about people with a seton and the most common comment is that the loose seton is used for a much longer period than first told. My guessing is that it has something to do with the limitation in surgical options, a seton has hardly any side-effects, the severity of a fistula and the recurring rate. Therefore it's much easier to leave a seton in place. But that's just my guessing;)

How does it feel?

I have to be honest, my after surgery pain was quite severe. Maybe also because this was my 5th surgery in the same area. I always have surgery with a spinal anesthetic so the after surgery pain starts about 4 hours after surgery when the anesthetic is out of my system. For me it's best discribed as being raped with a tree trunk in my ano, as a matter of speaking. So thank god for morfine! Always remember that in these days in 2013 it's not necessary to be in so much pain, so make sure you get the right amount of painkillers. The most severe pain will go away in a couple of days and will make place for the discomfort and getting used to the feeling of the seton at every move you make. There are some lucky ones that don't feel the seton at all, if so, I am sincerely happy for you:-) In all the other cases I guess it's just a matter of getting used to the feeling. It's not painfull, just not very comfy especially when you take a long walk in very warm weather. Now there are times I forget I have a seton.  

Life with a seton

I have had no restrictions after my seton was placed. I can use the bathtub, go swimming, sport, have sex, eat and drink normally, etc. You just have to figure out for yourself  at what time you think you're ready for taking part in activities again. I have to admit that because of the placing of the seton and the fact that pus is still coming out of the opening I sometimes feel less sexy than before. But then I keep in mind that I'm glad there is such a thing as a seton to prevent me from beeing in the hospital with an abscess every month. Now it's only every two months;) If you are in a relationship or single and dating, the seton shouldn't hold you back on being intimate. If you are with te right person he/she will understand your initial insecurity and support you.  

What is a perianal abscess?

First of I will start by telling you what an abscess is: an abscess is a collection of pus. It has some resemblance with for instance a pimple. Except an abscess can grow really big and it's more like a capsule filled with pus due to an infection process. It can be caused by an infection, bacteria or even a splinter.

And what is pus? I know this can gross some of you out, but I really had no idea what I had to picture myself when they were talking about pus. In my mind it had some resemblance with the white stuff from pimples. Don't worry I'm not gonna show you any pictures (you just youtube 'abscess drainage' and you know why not;)). I think I can describe pus best as a light pinkish milky fluid with a particular smell that I recognize immediately.

Back to the abscesses.. As I said earlier I have had several perianal abscesses.

A perianal abscess can be formed when for instance a hair has grown into your butt and started to infect. It can also be caused by an anal infection, fissure or STD. I've had three male hospitalroomies with an abscess due to ingrowing hair. That's the most common abscess. That's also why more men than woman have abscesses. My abscesses are caused by the fistula as a symptom of Crohn's.

When you have a perinanal abscess you start to feel a horrific pain in your ano, in your butt, near your butt, etc. Especially when you sit down or walk. I once asked my surgeon why it hurts so badly, I mean, it's in my butt and that's mostly contains fat. How can something in fat hurt? She told me, that it hurts simply because the abscess creates a whole in a space where there's no space to make a whole. It keeps growing and growing, trying to make a way out. And that way out is usually the skin on your butt. That's when you start feeling a bumb. Besides the pain you can start feeling sick, get a fever, chills and the bumb can turn red.

Sometimes an abscess can burst by itself. But most of the time you really have to go see a doctor who then will drain the abscess. With a 'simple' abscess it can be done without any anesthetics. I've read blogs with people telling they just drain an abscess themselves. (Un)fortunately my abscesses can only be drained in the hospital by a good surgeon.

As soon as the abscess is drained you will feel the worst pain is gone. What's usually left is the pain of the surgery itself. You will come out of the surgery with an open wound. When the abscess wasn't to deep you can leave the hospital the next day. They will probably let you choose between taking care of the open wound yourself by showering the wound twice a day or get homecare. Homecare means that you get a nurse twice a day who will clean out the open wound with (salty)water. The nurses will use a drain or catheter to get into the wound so it can be flushed properly. I've had some bad experiences with the catheters and flushing because it just kept hurting so much. Eventually they gave me a morfine injection half hour before they were gonna clean the wound(s). When the wound is cleaned you get a bandage that will protect the wound from outside infections.

Sometimes they also use gauze that they will stuff into the open wound, just to keep it from closing. When a wound is still not infection free when it closes you will soon be having another infection. The problem with gauze is, that it has happened numerous times that someone forgot to take it out while taking care of the wound. In that case the pain will increase and the wound will get infected again. I've had that ones, omg that started to hurt after a few days, after that my surgeon decided not to use homecare anymore but wanted me to shower the wound myself.

I've also had surgeries were they drained the abscess and left the wound open with a drain in it. I guess it's different each time depending on the place, severity and size of the abscess.

In my experience the open wounds will heal in about a month, depending on the size. With a drain and all inside it takes longer. I still wasn't able to sit for a long time, but that's because my fistula keeps producing pus and the wounds can't heal properly.
