Incisional Hernias

An incisional hernia occurs when an organ or tissue protrudes through a weakened area in the abdominal wall that has been previously surgically incised. This type of hernia develops at the site of a previous surgical incision, where the abdominal wall has not fully healed or where there is a natural weakness. If left untreated, incisional hernias can cause discomfort and pain and lead to complications.

Indications for Treatment

Treatment of an incisional hernia is typically indicated based on several factors:

Symptoms

Patients with symptoms such as pain, discomfort, or a noticeable bulge at the site of the previous incision may require treatment. The hernia can cause discomfort during physical activities or while straining.

Risk of Complications

Complications such as incarceration (trapping of the hernia content) or strangulation (compromised blood supply to the herniated tissue) necessitate prompt surgical intervention to prevent serious health issues

Impact on Quality of Life

When an incisional hernia affects daily activities, work, or overall quality of life, surgical repair is often recommended.

Prevention of Progression

Surgical repair is advised to prevent the hernia from enlarging or causing further complications, which could complicate treatment.

Steps Involved in the Treatment of Incisional Hernias

1. Diagnosis and Evaluation

Diagnosis is typically made through a physical examination, with imaging studies like ultrasound, CT scans, or MRI providing detailed information about the hernia’s size and extent.

2. Conservative Management

Conservative management may be recommended for small, asymptomatic hernias. This involves monitoring the hernia without immediate surgical intervention.

3. Surgical Repair

Surgical repair is the primary treatment for symptomatic or complicated incisional hernias. The two main surgical approaches are:

  1. Open Hernia Repair: An incision is made near the hernia site to access and repair the defect. The mesh may be used to reinforce the abdominal wall and reduce the risk of recurrence.
  2. Laparoscopic Hernia Repair: A minimally invasive technique using small incisions and a camera to guide the repair. The mesh is placed to support the abdominal wall from within.

4. Postoperative Care

After surgery, patients receive care that includes pain management, wound care, and follow-up visits to monitor healing and detect any potential complications.

Who Treats Incisional Hernias?

  • General Surgeons: Specialists in the surgical treatment of hernias. They perform both open and laparoscopic hernia repairs.
  • Gastroenterologists: They may be involved in the diagnosis and management of gastrointestinal issues related to the hernia but do not perform surgery.
  • Radiologists: Provide essential imaging services to diagnose and assess the hernia, aiding in treatment planning.
  • Primary Care Physicians: These are often the first point of contact for hernia symptoms and can refer patients to specialists for further evaluation and treatment.

Preparation for Incisional Hernia Surgery

  • Preoperative Evaluation: Includes a thorough physical examination, imaging studies, and blood tests to assess overall health and surgical suitability.
  • Informed Consent: Patients are informed about the procedure, including its risks, benefits, and alternatives, and must provide consent before surgery.
  • Lifestyle Adjustments: Patients may be advised to avoid certain activities or medications that could impact the surgery or recovery.
  • Dietary Instructions: Before surgery, patients may need to follow specific dietary guidelines, such as fasting or avoiding certain foods.

Recovery After Hernia Surgery

  • Hospital Stay: Most hernia repairs are done on an outpatient basis, but some patients may require an overnight stay for observation.
  • Pain Management: Pain management is essential, and patients may be prescribed medications or advised to use over-the-counter pain relievers.
  • Activity Restrictions: Patients are typically advised to avoid heavy lifting and strenuous activities for several weeks to allow for proper healing.
  • Wound Care: Proper care of the surgical site is crucial to prevent infection and promote healing.
  • Follow-Up Appointments: Regular follow-up visits are necessary to monitor recovery and address any issues that may arise.

Lifestyle Changes After Surgery

  • Activity Modification: A gradual return to normal activities is recommended, with attention to avoiding activities that could strain the abdominal wall.
  • Dietary Changes: Maintaining a healthy diet supports healing and prevents weight gain, which can stress the abdominal wall.
  • Weight Management: Achieving and maintaining a healthy weight reduces pressure on the abdominal wall and lowers the risk of recurrence.
  • Avoiding Heavy Lifting: Long-term avoidance of heavy lifting or straining activities to prevent recurrence.

Frequently Asked Questions

1. What is an incisional hernia?

An incisional hernia occurs when tissue protrudes through a weakened area in the abdominal wall at the site of a previous surgical incision.

2. What causes an incisional hernia?

Causes include a weak spot from a previous surgery, increased intra-abdominal pressure, or inadequate healing of the incision site.

3. How is an incisional hernia diagnosed?

Diagnosis involves a physical examination and may include imaging studies such as ultrasound or CT scans.

4. What are the symptoms of an incisional hernia?

Symptoms include a bulge at the incision site, pain or discomfort, and symptoms that worsen with physical activity or straining.

5. What are the treatment options for an incisional hernia?

Treatment options include conservative management for asymptomatic cases and surgical repair for symptomatic or complicated hernias.

6. What does hernia surgery involve?

Surgery involves repairing the hernia defect, often with mesh reinforcement. It can be performed via open surgery or laparoscopically.

7. Is hernia surgery painful?

Postoperative pain is common but manageable with prescribed medications and should gradually improve.

8. How long does recovery take after hernia surgery?

Recovery typically involves several weeks of avoiding heavy lifting and strenuous activities, with a gradual return to normal activities.

9. Are there risks associated with hernia surgery?

Risks include infection, bleeding, recurrence of the hernia, and complications related to anesthesia.

10. Can an incisional hernia come back after surgery?

Although surgery reduces the risk, hernias can recur, especially if underlying factors are not addressed.

11. How can I prevent an incisional hernia from recurring?

Prevent recurrence by maintaining a healthy weight, avoiding heavy lifting, and following postoperative care instructions.

12. How much does incisional hernia surgery cost?

Costs range depending on the type of surgery and healthcare facility.

13. Will insurance cover hernia surgery?

Many insurance plans cover hernia surgery, but coverage details and out-of-pocket expenses vary.

14. What lifestyle changes are recommended after hernia surgery?

Recommended changes include avoiding heavy lifting, maintaining a healthy diet, and managing weight.

15. What should I do if I experience complications after surgery?

Contact your healthcare provider immediately if you experience severe pain, fever, or signs of infection.
