VENTRAL AND INCISIONAL HERNIAS

BASIC INFORMATION

A ventral hernia occurs when abdominal tissue, fat, intestine, or other structures protrude through a weakened area or defect in the abdominal wall.

Some ventral hernias develop spontaneously, while others appear at the site of a previous surgical incision. These are known as incisional hernias.

Treatment depends on the size and location of the hernia, the symptoms it causes, previous abdominal operations, the patient's general health, and the risk of complications.

When surgery is indicated, repair may be performed through an open or minimally invasive approach, including laparoscopic techniques. The objective is not simply to close the opening but to restore the strength and function of the abdominal wall as safely as possible.

WHAT IS A VENTRAL HERNIA?

The abdominal wall is formed by several layers of muscle, fascia and connective tissue that contain and support the abdominal organs.

When one of these layers becomes weak or develops an opening, abdominal contents may push outward and create a visible or palpable bulge.

Ventral hernias include:

Umbilical hernias
Epigastric hernias
Incisional hernias
Other less common defects of the abdominal wall

An incisional hernia develops in an area previously operated on, where the abdominal wall has failed to maintain its original strength.

A hernia generally does not repair itself. It may remain stable for a long period, become progressively larger, or eventually cause symptoms or complications.

Not every ventral hernia requires immediate surgery. Small, reducible and minimally symptomatic hernias may sometimes be observed after appropriate surgical evaluation.

HOW DO YOU KNOW IF YOU HAVE A VENTRAL HERNIA?

The most common finding is a bulge or swelling of the abdominal wall, which may become more noticeable when standing, coughing, exercising or straining.

Symptoms may include:

A visible or palpable abdominal bulge
Pressure or heaviness in the affected area
Discomfort with physical activity
Pain when lifting or straining
Progressive enlargement of the bulge
Difficulty performing normal activities

Some hernias cause very little discomfort and are discovered incidentally.

However, a hernia may occasionally become incarcerated, meaning that its contents can no longer return into the abdomen. If the blood supply to the trapped tissue becomes compromised, the condition is called strangulation and requires urgent medical attention.

Seek immediate medical evaluation if you develop:

Sudden or severe pain
A previously reducible hernia that becomes firm or cannot be pushed back
Progressive abdominal distension
Persistent nausea or vomiting
Redness or significant tenderness over the hernia
Inability to pass stool or gas
Fever associated with increasing abdominal pain

These symptoms may indicate intestinal obstruction, incarceration or strangulation.

DOES EVERY VENTRAL HERNIA NEED SURGERY?

No.

Surgery is the only definitive way to repair the anatomical defect, but immediate surgery is not necessary for every patient.

Observation may be reasonable in selected patients with a reducible hernia that produces little or no discomfort, particularly when the risks of surgery outweigh the expected benefit.

Surgical repair is more commonly considered when the hernia:

Causes pain or significant discomfort
Is progressively enlarging
Limits physical activity
Becomes difficult to reduce
Has experienced episodes of incarceration
Causes intestinal obstruction
Significantly affects quality of life
Has anatomical characteristics that make future complications more concerning

The decision should be individualized.

ARE YOU A CANDIDATE FOR LAPAROSCOPIC REPAIR?

Possibly.

There is no single technique that is best for every ventral hernia.

Modern abdominal wall surgery includes several options:

Open repair
Laparoscopic repair
Other minimally invasive abdominal wall reconstruction techniques
Robotic repair in centers where the technology and expertise are available

The best approach depends on:

Size of the defect
Location of the hernia
Number of defects
Previous abdominal operations
Amount of scar tissue or adhesions
Previous hernia repairs
Presence and location of previous mesh
Obesity
Diabetes and other medical conditions
Smoking
Infection or contamination
Loss of abdominal domain
Overall surgical risk
Experience of the surgical team

Obesity does not automatically exclude a patient from minimally invasive surgery, although obesity increases the complexity of abdominal wall reconstruction and may increase the risk of wound complications and recurrence.

In selected elective cases, weight reduction, smoking cessation, improvement of diabetes control and nutritional optimization may reduce surgical risk before repair.

HOW IS A VENTRAL HERNIA REPAIRED?

Open repair

An incision is made over or near the hernia.

The surgeon identifies the hernia sac and abdominal wall defect, returns the abdominal contents to their normal position and reconstructs the abdominal wall.

Depending on the characteristics of the hernia, repair may involve sutures, surgical mesh, or more extensive reconstruction of the different muscular and fascial layers.

Large or complex hernias may require specialized abdominal wall reconstruction techniques.

Laparoscopic repair

Several small incisions are made away from the hernia.

A camera and specialized instruments are introduced into the abdomen. The abdominal contents are separated from the hernia, the defect is evaluated and the abdominal wall is reconstructed.

Mesh may be used to reinforce the repair.

Modern minimally invasive techniques increasingly attempt to restore the normal anatomy of the abdominal wall rather than simply placing a patch across an open defect.

Laparoscopic ventral hernia repair is generally performed under general anesthesia.

WHY IS MESH USED?

Surgical mesh provides reinforcement while the patient's tissues heal and integrate with the prosthetic material.

For many incisional and ventral hernias, especially larger defects, mesh significantly reduces the risk of recurrence compared with closure using sutures alone.

Mesh can be placed in different anatomical planes of the abdominal wall.

Depending on the operation, it may be positioned:

Above the muscular fascia
Between muscular or fascial layers
Behind the abdominal muscles
In the preperitoneal space
In selected techniques, inside the abdominal cavity

Whenever technically appropriate, modern abdominal wall reconstruction often favors placement of the mesh within or behind the muscular layers, limiting direct contact between prosthetic material and the abdominal organs.The type, size and position of the mesh should therefore be selected according to the specific repair rather than using the same technique for every patient.

WHAT SHOULD YOU EXPECT AFTER SURGERY?

Recovery varies considerably.

A small primary hernia repaired electively is very different from reconstruction of a large recurrent incisional hernia.

Many patients can walk within hours after surgery and progressively resume normal daily activities.

Pain or discomfort is expected during the first few days and should gradually improve.

Depending on the operation, patients may be discharged the same day or remain hospitalized for observation.

You should follow your surgeon's instructions regarding:

Wound care
Showering
Driving
Exercise
Lifting
Returning to work
Diet
Medication
Use of an abdominal binder when indicated

There is no single lifting restriction appropriate for every hernia repair. Activity should be progressively increased according to the procedure performed, symptoms and your surgeon's instructions.

IS SWELLING AFTER SURGERY NORMAL?

Some swelling around the surgical area is common.

A seroma, or collection of clear fluid in the space previously occupied by the hernia, may develop after repair.

Many seromas are absorbed naturally over several weeks.

They should not automatically be punctured or drained because introducing a needle may increase the risk of infection, particularly when surgical mesh is present.

Persistent, painful, enlarging or clinically concerning fluid collections should be evaluated by the surgeon.

WHAT COMPLICATIONS CAN OCCUR?

Ventral hernia repair is generally safe, but no surgical procedure is free of risk.

Possible complications include:

Bleeding
Hematoma
Seroma
Surgical-site infection
Mesh infection
Injury to the intestine or other abdominal organs
Urinary retention
Respiratory complications
Deep-vein thrombosis or pulmonary embolism
Cardiovascular complications
Persistent or chronic pain
Adhesions
Bowel obstruction
Recurrence of the hernia
Need for another operation

The probability of these complications varies considerably according to the patient's health, size and complexity of the hernia, previous operations and type of reconstruction performed.

Mesh infection is uncommon but can be a serious complication. Some infections can be treated without removing the prosthesis, while others may require partial or complete mesh removal.

WHEN SHOULD YOU CONTACT YOUR SURGEON AFTER SURGERY?

Contact your surgical team promptly if you develop:

Fever
Increasing rather than decreasing pain
Persistent vomiting
Progressive abdominal distension
Shortness of breath
Difficulty urinating
Significant wound redness
Purulent or foul-smelling drainage
Persistent bleeding
Sudden enlargement of the surgical area
Any symptom that concerns you

FREQUENTLY ASKED QUESTIONS

How long does recovery take?

It depends on the hernia and the operation performed.

Some patients undergoing relatively small repairs resume many routine activities within a few days. Larger abdominal wall reconstructions may require several weeks of progressive recovery.

Your occupation is also important. Returning to office work is different from returning to construction, heavy lifting or strenuous exercise.

Is laparoscopic surgery always better than open surgery?

No.

Minimally invasive surgery may decrease wound complications and shorten hospitalization in appropriately selected patients, but open surgery remains the best option for many complex hernias.

The objective is not to make the smallest incision possible. The objective is to obtain a safe, durable and anatomically appropriate repair.

Can the hernia come back?

Yes.

No technique can guarantee that a hernia will never recur.

Recurrence depends on several factors, including the size and complexity of the original hernia, surgical technique, obesity, smoking, diabetes, wound infection, tissue quality and previous repairs.

Appropriate technique and optimization of modifiable risk factors can reduce this risk.

Will I need mesh?

Not necessarily, but mesh is recommended for many ventral and particularly incisional hernia repairs because it decreases recurrence compared with suture repair alone.

The decision depends on the type and size of the hernia, tissue quality, contamination and surgical technique.

Will my insurance cover the operation?

Coverage depends entirely on your individual insurance policy, deductible, coinsurance, waiting periods, exclusions and medical-necessity criteria.

Our team can help provide the medical documentation required for evaluation by your insurance company, but authorization and reimbursement ultimately depend on your insurer and policy.

SPECIALIZED EVALUATION IS IMPORTANT

A ventral or incisional hernia is not simply a “hole that needs a patch.”

Proper treatment requires evaluation of the abdominal wall as a whole, including the location and dimensions of the defect, previous operations, muscle function, existing mesh, associated medical conditions and the patient's individual needs.

The appropriate solution may range from observation of a small asymptomatic hernia to laparoscopic repair or complex abdominal wall reconstruction.

The safest approach is determined after a complete surgical evaluation.
