Procedure definition

A ventral hernia repair fixes a weakness or opening in the abdominal wall that allows internal tissues or organs to bulge outward. These hernias can occur anywhere along the midline of the belly and often develop at the site of a previous surgical incision (called an incisional hernia). Others arise spontaneously from strain, pregnancy, or prior trauma.

The purpose of surgery is to return the herniated tissue to its proper position and strengthen the weakened area of the abdominal wall. There are several approaches:
• Open repair: a single incision is made over the hernia; the surgeon pushes the contents back in, removes scar tissue, and covers the defect with a mesh patch to reinforce the wall.
• Laparoscopic or robotic repair: performed through 3–4 small incisions with a camera and instruments; mesh is placed from the inside. This option usually results in less pain and a faster return to normal activity.
• Component separation or complex abdominal wall reconstruction: used for large or multiple hernias to rebuild muscle layers and achieve durable closure.

Most ventral hernia operations take 1–3 hours, depending on size and complexity.

Why it’s done

A ventral hernia does not heal without surgery. Over time, it can enlarge and cause discomfort, cosmetic bulging, or a sense of abdominal weakness. The main reason for repair is to prevent bowel incarceration (getting stuck) or strangulation (loss of blood flow), which are emergencies.

Many people also choose repair for functional reasons—improving core stability, reducing pain, and restoring a normal abdominal shape.

When hernias are small and cause minimal symptoms, watchful waiting may be reasonable, but studies show that 30–50% of such patients will develop pain or obstruction within several years.

Large or complex hernias often require preoperative optimization—weight loss, smoking cessation, and control of diabetes—to reduce recurrence and infection risks.

Risks & complications

Because ventral hernias vary widely in size and location, complication rates also vary.

Overall complication rate: 10–25% (mostly minor issues such as wound fluid collections).

Typical ranges:
• Recurrence: 5–15% with mesh; higher (20–40%) without mesh or in contaminated fields.
• Seroma (fluid collection): 10–20%.
• Wound infection: 5–10%, more common in large open repairs.
• Mesh infection: 1–3%; may require mesh removal.
• Bleeding or hematoma: 1–3%.
• Chronic pain or stiffness: 5–15%.
• Bowel injury or obstruction: 1–2%.
• Mortality: <0.5% in elective repairs; up to 5% in emergencies with strangulated bowel.

Advances such as biologic mesh, preoperative botulinum toxin to relax muscles, and minimally invasive approaches have reduced complication rates in experienced centers.

Recovery

Hospital stay: 1–2 days for laparoscopic repairs; 3–5 days for large open or complex reconstructions.

Pain & mobility: Expect soreness for a week or two. Early gentle walking is encouraged to prevent clots and lung problems. Avoid lifting >10–15 lbs for 4–6 weeks to protect the repair.

Activity: Most people return to desk work within 2–3 weeks (laparoscopic) or 4–6 weeks (open). Full physical activity or heavy labor may take 6–12 weeks. Wearing an abdominal binder can help support the muscles during early healing.

Wound care: Keep incisions clean; drain tubes (if placed) are removed in 3–5 days. Call your surgeon if swelling, redness, or drainage occurs.

Long-term: Mesh provides durable reinforcement, but proper lifting technique and weight management are crucial to prevent recurrence.

Surgeon types

Ventral hernia repair is performed by General Surgeons or abdominal wall reconstruction specialists. Large or recurrent hernias may be handled by surgeons who focus specifically on complex abdominal wall repair using component separation or robotic methods. Outcomes are best in high-volume centers where multidisciplinary teams can manage wound care, nutrition, and rehabilitation.
