Incisional Hernia Repair

Incisional Hernia Repair

An Incisional Hernia Repair is a surgical procedure to fix a protrusion of tissue or an organ (usually the intestine) through a previously made surgical scar. This occurs when the abdominal wall muscles fail to heal completely or weaken over time following an earlier surgery.

When You Should Consider Incisional Hernia Repair

• A visible bulge or lump at the site of a previous surgical scar.

• A bulge that becomes more prominent or painful when coughing, straining, or lifting.

• Persistent aching or pressure at the previous incision site.

• Nausea or vomiting if the protruding tissue becomes trapped (incarcerated).

• Confirmation of a muscle "defect" via CT scan or physical examination.

Methods of Incisional Hernia Repair

• Open Repair: A traditional approach involving an incision over the old scar, often used for very large hernias or complex cases.

• Laparoscopic Repair: A minimally invasive method using small "keyhole" incisions, CO2 gas, and a camera to repair the defect from the inside.

• Robotic-Assisted Repair: A modern variation of laparoscopic surgery offering enhanced precision for medium to large hernias.

• Tension-Free Mesh Repair: The use of synthetic or biologic mesh to reinforce the abdominal wall, significantly reducing the risk of recurrence.

How Incisional Hernia Repair Is Performed

• Sac Reduction: The surgeon identifies the hernia sac and carefully pushes the protruding tissue or intestine back into the abdominal cavity.

• Adhesiolysis: Freeing the intestine from old scar tissue or adhesions that may have formed since the previous surgery.

• Mesh Placement: A flexible, permanent screen (mesh) is secured over or under the muscle layer to act as a scaffold for new tissue growth.

• Fixation: The mesh is secured using sutures, tacks, or specialized surgical staples to ensure it remains in a "tension-free" position.

• Abdominal Wall Reconstruction: In complex cases, the surgeon may rearrange muscle layers to achieve a more natural and strong closure.

Pre-Procedure Preparation

• Quitting smoking for several weeks to improve blood flow and tissue healing.

• Weight management and stabilization of blood sugar levels to minimize the risk of repair failure.

• Fasting (NPO) as directed before undergoing general anesthesia.

• Evaluation of the old surgical site to plan the best approach (open vs. minimally invasive).

Tests Before Incisional Hernia Repair

• Physical Exam: To feel for the bulge and assess the strength of the surrounding abdominal wall.

• CT Scan: The primary imaging tool used to measure the exact size of the muscle defect and identify the contents of the hernia.

• Blood Panels: To check for signs of infection or uncontrolled diabetes that could affect recovery.

• Pre-Surgical Optimization Review: Assessment of lifestyle factors (BMI, smoking status) that impact surgical success.

Life After Incisional Hernia Repair

• Hospital stays range from same-day discharge for laparoscopic cases to 3–5 days for large open repairs.

• Use of an abdominal binder (elastic wrap) for 4–6 weeks to support the new repair.

• Strict activity restrictions, including no heavy lifting (>5 kg) for 6–8 weeks.

• Immediate encouragement of gentle walking to prevent blood clots during the early recovery phase.

• Monitoring for seromas (fluid collection) or signs of mesh infection at the incision site.

Benefits of Incisional Hernia Repair

• Significantly reduces the risk of hernia recurrence from 30–50% (without mesh) to below 10% (with mesh).

• Restores the structural integrity and strength of the abdominal wall.

• Eliminates the risk of life-threatening complications such as bowel obstruction or strangulation.

• Relieves chronic pain and discomfort associated with the protruding tissue.
