What Is the Success Rate of Fistula Surgery?
BlogAre you asking, “What is the success rate of fistula surgery?” Let me tell you straight:
Fistula surgery works well for most people—about 85% to 95% of patients get relief, depending on the fistula type, the operation, and how you recover.
Hi, I’m Dr. Neeraj Rayate, a surgeon at DOSS India in Pune, and I’ve treated many patients just like you—folks dealing with fistulas and unsure about surgery because of all the confusion out there.
I understand your worries—surgery can feel like a big step, and you just want clear answers.
In this article, we’ll talk about what fistula surgery involves, what makes it successful, and what you can expect afterwards. I’ll share some insights from my clinic, answer your doubts, and give you simple tips to feel confident.
Let’s go through this together, step by step, so you can decide what’s right for you!

What Is a Fistula in Simple Terms?
Picture your body as a home with pipes running inside—like your stomach, intestines, or bladder.
A fistula is an extra little passage that forms where it shouldn’t, connecting two areas—like a leak from your intestine to your skin or near your backside.
It’s not natural, and it can cause discomfort, leakage, or even infections.
Fistulas often come from things like an infection—say, a bad boil—or problems like Crohn’s disease, where your gut gets swollen and irritated.
For many, it’s an anal fistula near the bottom, and I know it can feel troubling or embarrassing to talk about.
But don’t worry—we’ll sort it out.
What Does Fistula Surgery Do?
Fistula surgery is about fixing that unwanted passage—either closing it or clearing it so it stops causing problems.
It’s like repairing a cracked water pipe at home—you stop the leak and make things work properly again.
The aim is to stop the discharge, ease your pain, and keep infections away for good.
There are different ways to do this, depending on your fistula. We’ll cover those soon, but first, let’s get to that success rate you’re curious about.
How Often Does Fistula Surgery Work?
When we say “success,” we mean the fistula heals, the trouble stops, and it doesn’t come back.
For most people, surgery does this beautifully—about 85% to 95% of the time. That’s a very good chance to get back to normal! But it’s not the same for everyone.
Here’s why it changes:
- Fistula Type: Small, straight ones heal better—often 90% or more. Bigger, twisty ones might be closer to 85%.
- Operation Type: Some methods work better than others—I’ll explain those next.
- Your Body: If you’re otherwise healthy, it helps. Things like diabetes can slow healing a bit.
- Care Afterwards: Following advice after surgery makes a big difference.
In my practice in Pune, I see these numbers hold true, but your own success depends on your specific case.
Let’s look at what’s behind those odds.
What Are the Types of Fistula Surgery?
Surgery isn’t one-size-fits-all—it’s like choosing the right tool for a job. Here’s what we might do:
1. Fistulotomy
This is the most common for anal fistulas. We open the passage and let it heal naturally from inside—like smoothing out a folded cloth. Success? Around 90%-95% for simple ones. It’s very effective if the fistula isn’t too deep.
2. Seton Placement
For more complicated fistulas, we put a soft thread through the passage to keep it draining. It’s like a temporary fix to control things, often leading to 85%-90% success when we follow up with another step.
3. Laser Closure
We use a laser to close the passage—no big cuts, just precise work. Success is about 80%-90%. It’s good for avoiding damage nearby, though it’s trickier for complex cases.
4. Flap Procedure
We take a small piece of your own tissue to cover the fistula—like patching a hole in your wall. It’s for tougher ones, with success around 85%-90%, depending on how it heals.
I’ll check your fistula—maybe with a small camera or scan—to pick the best option for you.
What Helps Surgery Work Well?
Success isn’t just my job—it’s a partnership. Here’s what makes it more likely to work:
- Simple Fistula: A short, easy path heals faster than a long, winding one.
- Your Health: Eating well, no smoking, and keeping sugar levels in check help your body mend.
- Experienced Surgeon: I’ve done this many times, and that skill boosts your chances.
- Aftercare: Keeping things clean and resting properly locks in the healing.
A man in his 30s came to DOSS India with a small fistula near his backside. He was fit, followed my eating tips, and we did a fistulotomy. He was fine in a few weeks—classic 95% success. It was straightforward, and he did his part.
Why Doesn’t It Work Sometimes?
Even with the best efforts, surgery fails 5%-15% of the time—the fistula might come back or not heal fully. Here’s why:
- Twisty Tunnels: If it’s got branches we miss, it can reopen.
- Infections: Germs left behind can stir trouble.
- Healing Issues: If your body’s slow to recover, it struggles.
- Not Resting: Ignoring advice—like overdoing it too soon—can mess it up.
If it doesn’t work, we don’t give up. We look again, maybe tweak the plan, and go for round two. It’s a bump, not a dead end.
How Do We Know It’s Successful?
Success means more than just closing the fistula. It’s about:
- No more leakage or pus.
- Pain disappearing.
- No new fistulas showing up later.
Research backs this up—85%-95% of surgeries do the trick. But I care about your daily life too: Are you feeling good again? That’s what counts.
What Happens After Surgery?
Recovery is key to success. Here’s what it’s like:
- First Few Days: A bit of soreness or oozing—totally normal. Rest and warm water soaks help.
- 2-6 Weeks: You’ll feel better, move easier—things start settling.
- Long Run: By 6-8 weeks, most are back to routine if it heals well.
Tips for Recovery:
- Soak in warm water (sitz baths) twice a day.
- Eat fruits and dal—keeps your stomach soft.
- Don’t lift heavy things for a bit.
- Tell me if you feel feverish or see swelling.
Will It Hurt? Any Risks?
Surgery isn’t painful during—we use medicines to numb you or help you sleep through it. Afterwards, expect some mild ache, like after a long walk—painkillers take care of it. Risks are there, but small:
- Infection (rare if you keep clean).
- Bowel control issues (very rare, only with deep fistulas).
- Fistula returning (5%-15% chance).
With modern techniques—like lasers or robotics—I keep these risks as low as possible.
Could You Skip Surgery?
You might wonder if surgery’s the only way.
For some tiny fistulas from infections, medicines or drainage might work—success maybe 20%-30%.
But for most, especially anal fistulas, surgery’s the surest bet because that passage won’t close naturally.
Other options like glue or threads help some, but they’re less certain—50%-70% at best.
What’s Your Success Rate?
Your own success depends on your fistula and you. Here’s the process:
- Check-Up: I look at it—maybe with a scan—to see its size and shape.
- Health Talk: Any smoking or sugar problems? We’ll factor that in.
- Plan It: I’ll suggest the surgery that fits you and tell you your chances.
A lady with a fistula from Crohn’s came to me. It was complex, so we used a flap method and managed her gut issues. She’s been fine for over a year—around 85% success. Her condition made it tougher, but we got there.
How Can You Help It Work?
You’re part of this too! Here’s what you can do:
- Stop smoking—it delays healing.
- Eat healthy—dal, sabzi, and fruits build strength.
- Stick to my advice—rest, baths, medicines.
- Keep me posted—any odd signs, let me know.
