Parastomal Hernia

Understanding a Parastomal Hernia

A parastomal hernia is a common condition that can develop after stoma surgery. It happens when part of the bowel or other abdominal tissue pushes through a weakened area of the abdominal wall around the stoma, creating a bulge or swelling.

Although a parastomal hernia can become larger over time, it does not always require surgery. Understanding the symptoms and knowing when to seek medical advice can help you manage the condition with confidence.

What Is a Parastomal Hernia?

A parastomal hernia develops around the opening where a stoma passes through the abdominal muscles. Creating a stoma requires an opening in the abdominal wall, which naturally creates a weaker area.

Over time, the muscles around the stoma can separate slightly, allowing part of the bowel or abdominal contents to push through. This causes a visible bulge or swelling beneath or around the stoma.

These types of hernias are very common, affecting up to 70% of people with a stoma. While they can affect the fit of a stoma appliance and cause discomfort, serious complications are uncommon.

Common Parastomal Hernia Symptoms

The symptoms of a parastomal hernia often develop gradually and may become more noticeable over time. Common symptoms include:

  • A bulge or swelling around the stoma
  • A change in the shape or size of the stoma area
  • Difficulty keeping a stoma appliance securely in place
  • Discomfort or aching around the stoma
  • A feeling of pressure when standing, coughing or lifting
  • The hernia becoming more noticeable during physical activity

Treatment for a Parastomal Hernia

Not every parastomal hernia requires surgery. Many people successfully manage their symptoms with lifestyle changes, abdominal support garments and regular monitoring.

If the hernia causes significant discomfort, problems with the stoma appliance or affects your quality of life, specialist assessment may be recommended. A hernia surgeon can determine whether surgery or continued conservative management is the most appropriate treatment.

When Should You Seek Medical Advice?

Most parastomal hernias develop slowly and can often be managed without surgery. However, you should seek medical advice if:

  • The bulge suddenly becomes much larger
  • You develop severe pain around the stoma
  • Your stoma stops working normally
  • The area becomes red, swollen or very tender
  • You experience nausea or vomiting alongside the hernia

These symptoms could indicate a more serious problem that requires urgent assessment.

How we've helped make a difference

Today I am three weeks beyond the hernia repair I received and just want to write and thank you all for the superb treatment. Everyone I met was entirely professional, very caring, very reassuring and utterly tuned in to the human condition. I would be most grateful if you would pass on my sincere thanks to all who cared for me that day. I will be eternally grateful.

Surgeon and support team are world-class! I very much appreciated the way my questions/concerns were addressed before the surgery. Surgery was very smooth and I would recommend the team to anyone whole-heartedly. 48 hours after surgery, I drove my car for 3 1/2 hours from Zurich to the Valais. says it all...
JG
Excellent team, friendly and competent. Excellent treatment and care given. No pain killers needed and I was able to travel home on public transport the same day. I’m 73 years old. It’s important to listen to advice given as everyone is different.

Past Patient
One page on your website told me absolutely everything (and more) that I was interested in finding out. I would have had to read several different pages on several different sites to get the understanding that one page of your website delivered very thoroughly in a nutshell!
Past Patient
I believe yourself and your team should be recognised for your amazing work. After a major but successful operation, I have never had one minute of pain and I believe I’ve got a new lease of life. I would just like to thank you and your team for making this possible.

Frequently Asked Questions

Practical answers to the things patients ask us most.

Are hernias normally repaired by hernia specialists?

+

Most hernias around the world are repaired by general surgeons as just one of the list of procedures they perform. Hernia is not a subject that has attracted enough interest generally to make it a specialised area. The slow development of modern hernia techniques is a result. We feel that hernia needs specialisation.

How can I know if hernia surgery provided at my local hospital really is the same as at The British Hernia Centre?

+

The easiest way to compare is to start with these simple questions. For example,

How many tens of thousands of hernia cases has your surgeon and his team performed? (Always ask that question) Is it done routinely under just local anaesthesia? Will you need overnight hospital admission at all? Will you be able to return to work and normal activities in the same amount of time? Are the risks of recurrence anything like the same? Do they have a 100% safety record and ZERO MRSA?

I had a hernia repaired and it has come back (recurred). Can’t it be fixed once and for all?

+

Traditionally (using previous techniques) many hernia repairs fail (recur) and they tend to fare even worse when they get repaired again. The failure rate is thought to double with each subsequent attempt.

Happily we have an established track record in repairing recurrent hernias and are repairs are as reliable as primary (first time) repairs. The risks of recurrence are an insignificant fraction of one percent.

See the page specifically on Recurrent Hernia.

Is it dangerous to ignore the hernia?

+

Most hernias, if not treated, do nothing more than get bigger. However, hernias can get very painful, often without warning and at their worst can strangulate, which can demand an ambulance and immediate emergency surgery or the consequences could be extreme.

Is there any way I can prevent myself from getting a hernia?

+

No. It is unfortunately something that can afflict anyone. About one in ten of us will have one, which is an awfully large number.

What different types of hernia are there?

+

There are several kinds of hernia, depending on where the muscle or tissue is weak. The most common is an inguinal hernia, which develops in the groin and is more common in men. Femoral hernias also occur in the groin and are more common in women. Umbilical hernias appear around the belly button, while incisional hernias develop through scars from previous surgery. The British Hernia Centre specialises in diagnosing and treating all types of hernia.
