Ventral Hernia

A ventral hernia occurs when abdominal tissue pushes through a weak area in the abdominal wall. Large or recurrent hernias may need minimally invasive, robotic or complex wall reconstruction.

Overview

A ventral hernia is any hernia that occurs through the front wall of the abdomen. It includes primary ventral hernias, such as umbilical and epigastric hernias that develop at natural weak points, and incisional hernias, which form at the site of a previous surgical incision. Incisional hernias are among the most common long-term complications of abdominal surgery, developing after a meaningful share of midline open operations (Liang et al., Annals of Surgery, 2017).

Ventral hernias range from small, fat-containing defects to very large hernias that contain much of the intestine and change the shape of the abdomen. They tend to enlarge over time and do not heal without surgery. Treatment ranges from watchful waiting for small, painless hernias in high-risk patients to minimally invasive mesh repair or complex abdominal wall reconstruction for large or recurrent hernias (Liang et al., Annals of Surgery, 2017).

Obesity is one of the most important factors in ventral hernia formation and repair outcomes, which is why combining hernia care with weight management is often the best strategy.

Types of Ventral Hernias

Umbilical hernia: at the belly button, the most common primary ventral hernia
Epigastric hernia: along the midline between the navel and breastbone, often small and containing fat (Henriksen et al., British Journal of Surgery, 2020)
Incisional hernia: through a previous surgical scar, including small laparoscopic port sites
Spigelian hernia: a rare hernia along the side of the abdominal muscles
Parastomal hernia: next to an ostomy

Groin hernias, such as inguinal hernias, are a separate category with different repair techniques.

Causes

Previous abdominal surgery: the incision may not heal with full strength, particularly after wound infection.
Natural weak points at the navel and along the midline above it
Increased abdominal pressure from obesity, pregnancy, chronic cough, constipation or heavy lifting
Poor tissue healing from smoking, diabetes, steroids or malnutrition
Connective tissue factors that run in families

Risk Factors

Obesity, which increases both the risk of developing a hernia and the risk of recurrence after repair (Liang et al., Annals of Surgery, 2017)
Wound infection after prior surgery
Smoking
Diabetes
Long midline incisions
Older age and male sex for incisional hernias
Previous hernia repair
Steroid or immunosuppressive medication

Who It Affects

Ventral hernias affect people who have had abdominal surgery, people with obesity, and women after pregnancy. Large and recurrent ventral hernias are especially common in patients who have had multiple abdominal operations.

Complications

Incarceration and strangulation of fat or intestine
Bowel obstruction
Skin thinning, ulceration or infection over large hernias
Loss of domain: in very large hernias, so much intestine lives outside the abdominal cavity that returning it requires special techniques
Back pain and posture problems from a weakened abdominal wall
Reduced quality of life and body image concerns

After repair, the most common complications are seroma, wound infection and recurrence. These risks rise with obesity, smoking, diabetes and larger hernias, which is why optimizing these conditions before surgery is a central part of modern hernia care (Liang et al., Annals of Surgery, 2017).

Symptoms

A bulge along or near a scar or the midline of the abdomen
A bulge that grows with standing, coughing or straining
Discomfort or aching, especially with activity
Constipation or bloating when intestine is in the hernia
Episodes of pain with nausea that may signal partial obstruction

Many people with incisional hernias first notice a bulge months to years after their original operation. Some describe a feeling of weakness or lack of support in the abdominal wall, especially when lifting or rising from bed.

Diagnosis

Physical examination
CT scan: the most useful test for planning repair; it measures the defect, shows its contents, identifies multiple hernias and assesses the abdominal wall muscles (Liang et al., Annals of Surgery, 2017)
Ultrasound for small hernias
Review of prior operative reports, especially for recurrent hernias or previous mesh

Differential Diagnosis

Diastasis recti (separation of the abdominal muscles without a true defect)
Lipoma
Seroma or fluid collection after surgery
Abdominal wall abscess
Spigelian hernia on the side of the abdomen

Lifestyle Modifications

Optimizing health before elective repair improves outcomes and lowers recurrence (Liang et al., Annals of Surgery, 2017):

Weight loss: reaching a lower BMI before repair reduces wound complications and recurrence.
Stop smoking at least four weeks before surgery.
Control blood sugar, ideally with HbA1c below about 8%.
Improve nutrition and protein intake.
Avoid heavy lifting and use proper technique.

Treatment Options

Watchful Waiting

Small hernias that cause few symptoms can sometimes be observed, especially when the patient has high surgical risk or is working on weight loss before repair.

Minimally Invasive Repair

Laparoscopic and robotic repairs use small incisions to close the defect and reinforce it with mesh. Robotic techniques allow mesh to be placed behind the muscle layers, and are well suited to many small and medium hernias, multiple hernias and patients with obesity (Liang et al., Annals of Surgery, 2017). See hernia repairs and robotic surgery.

Open Repair and Abdominal Wall Reconstruction

Large, complex or recurrent hernias may require open repair with component separation, a technique that releases layers of the abdominal wall muscles so the midline can be closed without tension, combined with mesh reinforcement (Liang et al., Annals of Surgery, 2017).

Combining Hernia Repair With Weight Loss

For patients with severe obesity, a staged approach, with weight loss through medication or bariatric surgery first and definitive hernia repair afterward, often gives the best long-term result. Small hernias may be repaired at the time of bariatric surgery.

Recovery After Ventral Hernia Repair

Recovery depends on the size of the repair. After minimally invasive repair of a small or moderate hernia, most patients go home the same day or the next day, return to desk work within one to two weeks and resume full activity within four to six weeks. Complex reconstructions may require several days in the hospital and two to three months before heavy lifting. An abdominal binder may be recommended for comfort.

What If I Already Have Mesh?

Recurrent hernias after previous mesh repair can usually be repaired again, often with a different approach that works through untouched tissue planes. Mesh infections are uncommon but may require removal of the old mesh before a new repair. Prior operative reports help your surgeon plan safely (Liang et al., Annals of Surgery, 2017).

When to See a Doctor

See a surgeon for any new bulge near a scar or along the midline of the abdomen, a hernia that is growing or causing pain, or a hernia that has come back after repair.

When to Seek Treatment

Seek emergency care if a hernia becomes painful, firm or discolored, cannot be pushed back, or is accompanied by vomiting, fever, bloating or inability to pass gas.

Long-Term Outlook

A well-planned repair, performed after addressing modifiable risk factors, gives most patients lasting relief and a stronger, more functional abdominal wall.

Prognosis

Most ventral hernias can be repaired successfully. Recurrence risk depends on hernia size, prior repairs, obesity, smoking and diabetes, which is why preoperative optimization matters (Liang et al., Annals of Surgery, 2017).

For large hernias in patients with severe obesity, studies show substantially higher recurrence after repair at a high BMI, supporting weight loss before definitive repair when it is safe to wait.
