The State of Prophylactic Mesh Augmentation.

Prophylactic mesh augmentation (PMA) is the implantation of mesh during closure of an index laparotomy to decrease a patient's risk for developing incisional hernia (IH). The current body of evidence lacks refined guidelines for patient selection, mesh placement, and material choice. The purpose of this study is to summarize the literature and identify areas of research needed to foster responsible and appropriate use of PMA as an emerging technique. We conducted a comprehensive review of Scopus, Cochrane, PubMed, and clinicaltrials.gov for articles and trials related to using PMA for IH risk reduction.We further supplemented our review by including select papers on patient-reported outcomes, cost utility, risk modeling, surgical techniques, and available materials highly relevant to PMA. Five-hundred-fifty-one unique articles and 357 trials were reviewed. Multiple studies note a significant decrease in IH incidence with PMA compared with primary suture-only--based closure. No multicenter randomized control trial has been conducted in the United States, and only two such trials are currently active worldwide. Evidence exists supporting the use of PMA, with practical cost utility and models for selecting high-risk patients, but standard PMA guidelines are lacking. Although Europe has progressed with this technique, widespread adoption of PMA requires large-scale pragmatic randomized control trial research, strong evidence-based guidelines, current procedural terminology coding, and resolution of several barriers.
