Open Incisional Hernia Repair

Open incisional hernia repair is a surgical procedure used to repair a hernia that occurs through a previous surgical incision. This type of hernia is also known as an incisional or ventral hernia.

Causes and Risk Factors

Incisional hernias can occur due to various factors, including:

• Weakened abdominal muscles
• Poor wound healing after surgery
• Obesity
• Chronic coughing or straining
• Previous abdominal surgery
• Aging
• Genetic predisposition

Symptoms

The symptoms of an incisional hernia may include:

• A bulge or lump in the abdomen, usually near the site of a previous surgical incision
• Pain or discomfort in the abdomen, especially when coughing, straining, or lifting heavy objects
• Nausea and vomiting
• Constipation or difficulty passing stools
• Abdominal tenderness or swelling

Surgical Procedure

The open incisional hernia repair procedure typically involves the following steps:

1. The patient is given general anesthesia to ensure comfort and relaxation during the procedure.
2. A surgical incision is made near the site of the hernia, usually along the previous scar line.
3. The surgeon carefully dissects the tissue to locate the hernia sac and any surrounding adhesions or scar tissue.
4. The hernia sac is then isolated and removed, and the defect in the abdominal wall is repaired using sutures or mesh material.
5. The mesh material is usually made of a synthetic or biologic material that provides additional support to the weakened area.
6. The surgeon may also use a technique called "component separation" to repair larger hernias, which involves separating and advancing the abdominal muscles to close the defect.
7. The incision is then closed in layers using sutures or staples, and the skin is usually closed with sutures or staples as well.

Types of Mesh Material

There are several types of mesh material that can be used for open incisional hernia repair, including:

• Polypropylene mesh: a synthetic mesh made from polypropylene fibers
• Polyester mesh: a synthetic mesh made from polyester fibers
• Biologic mesh: a mesh made from natural tissues, such as animal-derived collagen or human donor tissue
• Composite mesh: a mesh that combines different materials, such as polypropylene and polyester

Benefits and Risks

The benefits of open incisional hernia repair include:

• Relief from symptoms such as pain and discomfort
• Prevention of complications, such as bowel obstruction or strangulation
• Improved quality of life

The risks and potential complications of open incisional hernia repair include:

• Bleeding or hematoma
• Infection
• Adhesions or scar tissue formation
• Recurrence of the hernia
• Nerve damage or numbness
• Bowel injury or obstruction

Recovery and Follow-up

After open incisional hernia repair, patients typically require several weeks to recover. The following are some general guidelines for recovery:

• Avoid heavy lifting, bending, or straining for 4-6 weeks
• Avoid driving for 1-2 weeks
• Take pain medication as directed by the surgeon
• Follow a healthy diet and stay hydrated
• Attend follow-up appointments with the surgeon to monitor healing and remove sutures or staples

Outcomes and Prognosis

The outcomes of open incisional hernia repair are generally good, with most patients experiencing significant improvement in symptoms and quality of life. However, the prognosis depends on various factors, including:

• The size and location of the hernia
• The presence of any underlying medical conditions
• The type of mesh material used
• The surgeon's experience and skill level

Overall, open incisional hernia repair is a safe and effective procedure for treating incisional hernias. However, it's essential to discuss the potential benefits and risks with a qualified surgeon to determine the best course of treatment for each individual case.

Frequently Asked Questions (FAQs)

What is an open incisional hernia repair?
A surgical procedure to repair a hernia that occurs through a previous surgical incision.

What are the indications for open incisional hernia repair?
Typically performed for symptomatic or large hernias, or those causing bowel obstruction or strangulation.

How is the procedure typically performed?
Under general anesthesia, with an incision made near the site of the hernia to repair the defect.

What type of anesthesia is usually used?
General anesthesia, but sometimes regional or local anesthesia may be used.

Are there different types of open incisional hernia repairs?
Yes, including primary closure, mesh repair, and component separation techniques.

What are the benefits of using mesh in open incisional hernia repair?
May reduce recurrence rates and provide additional strength to the repair.

What are the potential risks and complications of the procedure?
Include infection, bleeding, bowel injury, and recurrence of the hernia.

How long does the recovery typically take?
Usually several weeks, with some patients taking longer to fully recover.

Are there any alternative treatments to open incisional hernia repair?
Laparoscopic hernia repair may be an option for some patients, depending on the size and location of the hernia.

Can the procedure be performed on an outpatient basis?
Sometimes, but often requires a short hospital stay for monitoring and recovery.
