Complex Abdominal Wall Hernias: Structured Use of Adjuvant Therapies

Area of Science:

• Abdominal Wall Reconstruction
• Surgical Innovation
• Hernia Repair

Background:

• Complex midline hernias pose significant surgical challenges.
• Component Separation Techniques (CST) are often necessary for tension-free closure.
• Adjuvant therapies like botulinum toxin type A (BTA), preoperative progressive pneumoperitoneum (PPP), and intraoperative fascial traction (IFT) aim to improve abdominal wall compliance and reduce surgical complexity.

Purpose of the Study:

• To evaluate the rate of CST utilization in abdominal wall reconstruction for complex midline hernias following adjuvant therapies.
• To assess the impact of combined adjuvant therapies on surgical approach.

Main Methods:

• A cross-sectional study included 44 patients undergoing midline complex abdominal hernia repair between June 2020 and June 2024.
• Patients received BTA, PPP, or/and IFT as adjuvant therapies.
• Exclusion criteria included non-midline hernias, non-elective surgeries, and follow-up less than 3 months.

Main Results:

• 61.4% of patients avoided CST after adjuvant therapies.
• Combined adjuvant techniques (BTA + PPP or BTA + IFT) were used in 45.5% of cases.
• Low recurrence rate (4.5%) and manageable complication rates (20.5% early, 9.1% late) were observed after a median 13-month follow-up.

Conclusions:

• Adjuvant therapies can significantly influence the surgical approach for abdominal wall reconstruction.
• Synchronous application of pre- and intraoperative adjuvant therapies may enhance effectiveness, enabling less disruptive surgical techniques.
