Abdominal Wall Reconstruction: Advances in the Last Decade

Abstract

The incidence of abdominal wall hernia (AWH) is increasing because of the aging population, obesity, and the increasing number of abdominal surgeries performed. Over the last decade, there have been many improvements with the introduction of novel techniques in the management of AWH. The development of component separation and bioprosthetic mesh has transformed the management of complex ventral hernias. An increased number of complex ventral hernia repairs are being done using minimally invasive methods, including component separation. With the introduction of three-dimensional laparoscopic technique and robotic platform, the technique of component separation for abdominal wall reconstruction (AWR) has become more reproducible. In the past decade, the prosthetic materials have greatly improved, including bioengineered smart scaffold tissues such as hydrogel and electrospun fibers that have shown promising results even in infected environment. Apart from advances in complex abdominal wall repair, patient-centric outcomes and the cost-effectiveness of hernia surgery also have gained focus in the management of AWH. Today, the field of hernia has become a discipline in itself due to a better understanding of the biomechanics and pathophysiology of AWHs. There has been a tremendous development in diverse surgical techniques for complex abdominal wall repair with huge advancements in the development of hernia implants transforming it from a simple hernia repair to the science of AWR. This review aims to summarize recent developments in the field of AWR, incorporating a brief overview of the management of AWH.
