Botulinum Toxin in the Surgical Treatment of Complex Abdominal Hernias: A Surgical Anatomy Approach, Current Evidence and Outcomes.

BACKGROUND/AIM: Abdominal wall hernias represent a common problem in surgical practice. A significant proportion of them entails large defects, often difficult to primarily close without advanced techniques. Injection of botulinum toxin preoperatively at specific points targeting lateral abdominal wall musculature has been recently introduced as an adjunct in achieving primary fascia closure rates.

MATERIALS AND METHODS

A literature search was conducted investigating the role of botulinum toxin in abdominal wall reconstruction focusing on anatomic repair of hernia defects.

RESULTS

Injecting botulinum toxin preoperatively achieved chemical short-term paralysis of the lateral abdominal wall muscles, enabling a tension-free closure of the midline, which according to anatomic and clinical studies should be the goal of hernia repair. No significant complications from botulinum injections for complex hernias were reported.

CONCLUSION

Botulinum is a significant adjunct to complex abdominal wall reconstruction. Further studies are needed to standardize protocols and create more evidence.
