A Collective Review of Gore Bio-A Absorbable Synthetic Mesh in Cruroplasty Reinforcement.

Background: Laparoscopic repair of hiatal hernia (HH) is associated with a considerable failure rate. Compared to suture repair alone, mesh-reinforced cruroplasty may be associated with fewer short-term recurrences, yet its use remains controversial. The aim of this study was to analyze the current literature assessing the use of Bio-A absorbable synthetic mesh in the reinforcement of primary crural closure after laparoscopic HH repair. Methods: A systematic review of primary literature in the MEDLINE and PubMed databases was conducted. We searched for investigations reporting patient outcomes in laparoscopic HH repair with onlay Gore Bio-A tissue reinforcement (W. L. Gore & Associates, Inc.) published between January 2008 and December 2019. The primary outcome was anatomical recurrence rate. Secondary outcomes were complication rate, symptomatic outcomes, and mortality. Results: Eight studies met inclusion criteria. There were two prospective and six retrospective cohort studies. In the included studies, laparoscopic HH repair was performed with Bio-A absorbable synthetic mesh in 734 patients. The anatomical recurrence data were extracted across all studies, and an objective recurrence was identified in 21/280 (7.5%) patients. There was only 1 (0.17%) mesh-related complication in the included studies. Conclusions: The use of Bio-A absorbable synthetic mesh in the repair of HHs may be promising, as it offers low rates of anatomical recurrence and mesh-related complications, but more data are still necessary to validate these findings. This collective review of literature is a basis for future randomized controlled trials to identify the most effective and safe mesh in the long term.
