Complex Abdominal Wall Reconstruction & Hernia Surgery

Complex abdominal wall reconstruction addresses hernias and abdominal wall defects that go beyond a routine repair. Patients are typically referred with large incisional hernias following previous abdominal surgery, recurrent hernias after one or more failed repairs, or complex defects associated with stoma reversal, previous mesh complications or infection.

The aim is to restore the form and function of the abdominal wall, reduce the risk of recurrence, and improve symptoms and quality of life. Treatment is planned individually after careful assessment of the hernia, the patient’s history and any prior repairs.

Symptoms vary with the size and location of the hernia and any previous repairs.

• A visible bulge in the abdominal wall, often at a previous scar.
• Discomfort or pain, particularly with activity, lifting or coughing.
• A feeling of heaviness or dragging in the abdomen.
• Difficulty with daily activities, posture or core strength.
• Episodes of obstruction, severe pain or skin changes. These require urgent review.

Assessment begins with a detailed history, including previous operations, mesh used, episodes of infection and any prior recurrences. Examination is supplemented by cross-sectional imaging (typically a CT of the abdomen and pelvis) to define the size and location of the defect, the quality of the surrounding tissues and the relationship of the hernia to other structures.

Where appropriate, multidisciplinary input is coordinated, including with anaesthetics, plastic surgery, stomal therapy and physiotherapy. Optimisation of weight, smoking, nutrition and diabetes is an important part of preparation for major reconstructive surgery.

Treatment is individualised. Smaller defects may be repaired using laparoscopic or open techniques with mesh reinforcement. Larger or more complex defects often require formal abdominal wall reconstruction, including component separation techniques to mobilise the abdominal wall layers and allow tension-free midline closure.

Mesh selection and position are tailored to the defect, the patient’s history and any previous contamination or infection. The rationale for the recommended approach, alternatives, expected benefits and risks are discussed in detail before any decision is made.

Recovery from complex abdominal wall reconstruction is more involved than for a standard hernia repair. Most patients stay in hospital for several days, with structured pain management, early mobilisation and a graded return to activity over several weeks to months.

Heavy lifting and strenuous exercise are typically restricted for 6 to 8 weeks, with a longer reconditioning period to rebuild core strength. A written recovery plan and clear follow-up arrangements are provided.
