Parastomal Hernia A common complication that needs special expertise
A bulge around your stoma or trouble keeping the bag in place? Learn about parastomal hernia and how it is treated.
In this article
A colostomy or ileostomy (stoma) is an opening made in the abdominal wall to bring the bowel to the surface after certain bowel operations. Because this opening passes through the abdominal muscles, it is a natural weak point that may widen over time, creating what is called a parastomal hernia. It is one of the conditions Dr. Mohamed Esmat includes within abdominal core surgery, as it requires precise experience in abdominal wall surgery.
Why does a parastomal hernia develop?
When a stoma is created, a passage is opened through the layers of the abdominal wall. With repeated abdominal pressure from coughing, movement and lifting, the opening around the bowel may widen and tissue or loops of bowel can push through beside it. This is one of the most common stoma complications, and the likelihood increases with time.
Excess weight
Obesity raises intra-abdominal pressure and weakens healing around the opening.
Chronic cough and constipation
Anything that repeatedly raises abdominal pressure increases the risk.
Tissue weakness
Older age, smoking and some medicines reduce tissue strength.
Surgical factors
The size and position of the opening relative to the muscles affect the risk.
Symptoms you may notice
The hernia may start with nothing more than a slight bulge around the stoma, then cause problems that affect daily life:
- A bulge around the stoma that grows on standing or coughing and shrinks when lying down.
- Difficulty keeping the stoma bag in place, with leaks that irritate the skin.
- A feeling of heaviness or pain around the opening.
- Change in the stoma’s shape or difficulty with irrigation for those who use it.
Sudden severe pain around the stoma, a darkening stoma colour, or no output with vomiting and abdominal distension may mean the bowel is trapped and require immediate emergency care.
Diagnosis
The hernia is often diagnosed by examination while standing and coughing, but a CT scan remains the most accurate tool for measuring the defect, seeing its contents and planning surgery — especially if the hernia is large or accompanied by an incisional hernia in the previous scar.
Treatment options
Not every parastomal hernia needs immediate surgery. Small hernias with few symptoms may be monitored with a dedicated stoma support belt, an adjusted bag type, and control of weight, cough and constipation. Hernias causing pain, repeated leaks or obstruction need surgical repair.
| Option | When it fits | Notes |
|---|---|---|
| Monitoring with a support belt | Small hernia, mild symptoms | Relieves symptoms but does not treat the hernia |
| Mesh repair | Most cases that need surgery | Best for reducing recurrence |
| Relocating the stoma | Selected cases | A hernia may form at the new site |
| Closing the stoma | If reconnecting the bowel is medically possible | Decided together with the colorectal surgeon |
Mesh repair is the most widely adopted approach today. It may be done laparoscopically or open, using specific techniques such as the Sugarbaker or keyhole methods or retromuscular techniques, chosen according to hernia size and any associated incisional hernia. Learn more about types of surgical mesh.
Can it be prevented?
Surgical experience suggests that some measures during stoma creation — such as a preventive mesh in selected cases and careful positioning of the opening through the rectus muscle — may reduce the risk. After surgery, keeping a healthy weight, avoiding heavy lifting in the early weeks, and treating chronic cough and constipation help protect the wall.
What raises the risk
- Lifting heavy weights soon after surgery.
- Continued weight gain.
- Smoking and chronic cough.
- Ignoring a small bulge until it grows.
What protects the wall
- Using a suitable support belt during exertion.
- Healthy weight control.
- Treating causes of raised abdominal pressure.
- Regular follow-up with an abdominal wall surgeon.
“A parastomal hernia needs a plan designed for each patient; what suits a small hernia is completely different from a large one with an associated incisional hernia.”
Dr. Mohamed EsmatConsultant hernia & abdominal wall surgeonFrequently asked questions
Does every parastomal hernia need surgery?
No. Small hernias with few symptoms may be monitored with a support belt, while painful hernias or those causing leaks or obstruction need repair.
Can the hernia come back after repair?
Recurrence is more likely with this type than others, but mesh repair by specialists reduces it significantly.
Can it be repaired laparoscopically?
Yes, in many cases. The surgeon chooses the best approach according to the hernia size and previous operations.
