Have you ever felt something strange, painful, or a small bulge in your lower abdomen or buttocks while sitting or standing? You may not have thought that this could be a hernia, but it is a slightly different, rarer condition. Today we are going to talk about such a condition, which is called a perineal hernia. Don't worry, we will talk about this simply, in a way that you can understand.
What is a perineal hernia? Let's understand it simply!
Okay, now let's see what these two words "perineal hernia" mean. Then this will be clearer to you.
- What is "Perineal"?
Simply put, the area of skin between your anus (where you poop) and your genitals (where your vagina is in women and your scrotum is in men) is called the perineum. This is part of our pelvic floor. The pelvic floor is a collection of muscles and tissues that are located under our stomach, between our legs, and that support some of our internal organs (such as the bladder, uterus, and intestines).
- What is a "Hernia"?
A hernia is when part of an organ, fatty tissue, muscle, or fascia, which is a supporting tissue , becomes weak and pushes out of that weak spot . It's like a balloon that slowly bulges out of one spot when you inflate it. Or, it's like a sidewall of an old tire that bulges out.
Then, a perineal hernia is a condition where the pelvic floor muscles in the perineum area become weak, causing a part of an organ or tissue in the abdominal cavity to push through. This can often occur as a rare side effect of surgery in the pelvic area. It can also be caused by certain illnesses and accidents. Very rarely, there are cases that are congenital.
Are there types of perineal hernias?
Yes, doctors classify these perineal hernias into the following main types:
- Acquired hernias: These occur after an accident, illness, or pregnancy.
- Congenital hernia: This is very rare. It is a condition that occurs at birth.
- Secondary Hernia: This is the most common type of hernia. It occurs after surgery.
How common is this perineal hernia?
Hernias are actually very common. They can occur in people of any age. The most common type of hernia is called an inguinal hernia, which is especially common in men. Imagine, about one in three people in the United States will develop a hernia in their lifetime.
However, perineal hernias are a very rare condition . They occur in a small percentage of people who undergo pelvic surgical procedures, ranging from 0.34% to 7%. Women are more likely to develop this type of hernia .
Why does this perineal hernia occur? What are the causes?
The main cause of a perineal hernia is damage to the muscles of your pelvic floor and the supporting tissue called fascia, which can become weak or stretched. This damage can be caused by:
- Major surgery: Especially open procedures that involve a large incision in the lower abdomen. These surgeries can cause a lot of tearing and stretching of the muscles and tissues of the pelvic floor. As these muscles and tissues weaken after surgery, the risk of an organ prolapse increases. This hernia usually occurs between 6 months and 5 years after surgery.
- Injuries
- Some Illnesses
- Pregnancy
Think of it like a mesh. That mesh holds our bladder, rectum, prostate in men, uterus, and vagina in women, preventing them from falling down. If that mesh becomes weak anywhere, that's where this hernia occurs.
What types of surgeries increase the risk of perineal hernia?
There are certain surgeries that increase the risk of developing this secondary type of perineal hernia. Let's look at a few examples:
- Abdominoperineal resection: This is a surgery for rectal cancer or anal cancer. The rectum, anus, and part of the large intestine called the sigmoid colon are removed. This can be done laparoscopically (through a few small incisions) or open (through a large incision). Both methods carry a risk of hernia.
- Low anterior resection (proctectomy): This surgery removes all or part of the rectum through an incision in the lower abdomen due to cancer. It is also a treatment for inflammatory bowel disease (IBD).
- Pelvic exenteration: This surgery removes the rectum and nearby organs such as the bladder, prostate, or uterus. In addition to rectal cancer, this surgery is also performed for prostate cancer in men and cervical cancer, uterine cancer, vaginal cancer, and vulvar cancer in women.
- Prostatectomy: This surgery for prostate cancer involves removing the prostate gland. It can be done using two methods: open radical prostatectomy and laparoscopic prostatectomy.
Who is at higher risk of developing a perineal hernia?
There are some factors that may increase the risk of developing this hernia:
- Being a woman: As mentioned before, women are at higher risk.
- Cancer treatments: Things like chemotherapy and radiation therapy.
- Having a history of smoking .
- Hysterectomy: This means surgery to remove the uterus.
- Rectal tumors or cancer .
- Use of immunosuppressants .
What organs can be affected by a perineal hernia?
When the pelvic floor is weakened after an accident or surgery, parts of these organs can be pushed into the abdominal cavity:
- Bladder
- Large intestine
- Omentum (This is a layer of fat that covers things like our intestines, liver, and stomach)
- Small intestine
- Uterus
What are the symptoms of a perineal hernia?
Some people with a perineal hernia may not have any symptoms. However, some may experience pain or discomfort when sitting . Other symptoms include:
- Difficulty urinating or defecating .
- A feeling of pulling or discomfort in the lower abdomen when standing.
- Small bowel obstruction or large bowel (intestinal) obstruction. (This is a slightly more serious condition.)
- The one with visible swelling in one buttock .
Imagine, Nimal, after a major surgery, finds it very difficult to sit for a few days. He feels like something is pushing inside his buttocks, like a ball. At first, he thought it was pain from the wound. But when he showed it to the doctor, he realized it was a perineal hernia.
How is perineal hernia diagnosed?
When you go to see a doctor, he or she will examine you. You may be able to feel the hernia sac when you touch it. Or you may be able to see it.
To confirm the diagnosis, you may be asked to have a CT scan or MRI . These scans can clearly see what's inside.
How is this treated?
A perineal hernia requires surgery to treat. The surgery involves putting the herniated organ back in place and sewing up the weakened muscle or fascia. Sometimes, a synthetic mesh or muscle flap is used to strengthen the pelvic floor.
There are several surgical methods for hernias:
- Laparoscopy: This is a procedure in which a thin tube with a camera attached, called a laparoscope, and other instruments are inserted through a few small incisions. It is also called "keyhole surgery."
- Robotic surgery: This is also an advanced surgical procedure performed using a laparoscope and a robot.
- Transabdominal: In this, surgery is performed by making an incision in the abdomen where the hernia is located.
- Transperineal: In this, the surgery is performed through a small incision in the perineum area.
The doctor will decide which surgical procedure is best for you.
Can perineal hernias be prevented?
Although it cannot be completely prevented, there are some things you can do to reduce the risk.
You can strengthen your pelvic floor muscles by doing Kegel exercises .
The surgeries that cause secondary perineal hernias are often life-saving and necessary surgeries. So they cannot be avoided. However, after surgery, it is very important to follow the doctor's instructions exactly . If you follow the instructions about how to start working out and lifting weights, you can reduce the risk of developing a hernia.
How does a person with a perineal hernia recover?
Most of the time, perineal hernia surgeries are successful . You are less likely to have other problems or complications. You can rest as your doctor tells you and gradually return to normal activities.
When should I see a doctor?
If you experience any of these symptoms, definitely see a doctor:
- If you have a swelling or lump in your perineum or buttocks .
- If there is a change in urination or bowel movements (such as difficulty, needing to go more frequently).
- If you feel pain or discomfort while sitting or standing .
Especially if you've recently had pelvic surgery and are having difficulty sitting or standing, be sure to see a doctor and get checked out. It could be a perineal hernia.
What should I ask my doctor?
When you go to see a doctor, it's a good idea to ask these questions:
- Why did I get this perineal hernia?
- What kind of surgery do you recommend for me?
- What can I do to prevent a hernia from developing in the future?
- Should I be concerned about symptoms of complications ?
Summary and things to remember
So, a perineal hernia is a condition where an organ or tissue from the abdomen pushes through the perineum due to weakness in the pelvic floor muscles. Although this is a rare condition, it can also occur due to certain illnesses, accidents, or pregnancy, especially after pelvic surgery. Symptoms include pain when sitting, swelling, and difficulty defecating/urinating. The best treatment for this is to repair the hernia through surgery and strengthen the weakened muscles.
The most important thing is that if you have these symptoms, don't ignore them and see a doctor right away for advice. Early detection makes treatment easier and you can recover faster. Don't worry, there are good treatments for this!
