1. Indications

The procedure for repairing a recurrent incisional or ventral hernia is indicated in the following situations:

• Recurrent Incisional Hernia The patient has a hernia that has reappeared at the site of a previous surgical incision.
• Incarcerated Hernia The hernia contents cannot be pushed back into their normal position within the abdominal cavity.
• Strangulated Hernia The hernia is associated with compromised blood supply to the herniated tissue, requiring immediate surgical intervention.

2. Procedure

The surgical procedure for repairing a recurrent incisional or ventral hernia involves several critical steps to ensure effective correction of the hernia and restoration of the abdominal wall integrity.

• Step 1: Preparation and Anesthesia The patient is positioned appropriately, and anesthesia is administered to ensure comfort during the procedure. The surgical area is then prepared and draped to maintain a sterile environment.
• Step 2: Incision and Exposure An incision is made over the site of the recurrent hernia. The old scar tissue is excised, and the skin on either side of the incision is carefully freed to expose the hernia sac. This step is crucial for accessing the underlying structures.
• Step 3: Dissection of the Hernia Sac The hernia sac is opened, and any adherent omentum or bowel is meticulously dissected away from the inner surface of the sac and the abdominal wall. This dissection allows for a clear view of the hernia contents and the surrounding tissues.
• Step 4: Excision of the Sac The hernia sac, along with its peritoneal lining, scar tissue, and any residual suture material from previous surgeries, is excised. This step is essential to remove any potential sources of recurrence.
• Step 5: Repair of the Abdominal Wall Once the sac is removed, the normal tissue of the linea alba is exposed. The abdominal wall is then sutured closed, ensuring that the layers are properly aligned. If there is excess skin, it is also removed before final suturing.
• Step 6: Closure Techniques For larger defects, the shoelace technique may be employed, where incisions are made in the anterior rectus sheaths to expose the rectus muscles. The hernia contents are returned to the abdominal cavity, and the linea alba is reconstructed by suturing the muscle strips together. In cases where the defect is significant, mesh reinforcement may be utilized to provide additional support.

3. Post-Procedure

After the procedure, the patient is monitored for any signs of complications, such as infection or recurrence of the hernia. Pain management is provided as needed, and the patient is given specific instructions regarding activity restrictions and wound care. Follow-up appointments are scheduled to assess the healing process and ensure that the abdominal wall is recovering appropriately. Patients are typically advised to avoid heavy lifting and strenuous activities for a specified period to promote optimal healing.
