Hiatal hernia repair with biosynthetic mesh reinforcement: a qualitative systematic review.

Abstract

INTRODUCTION:

Reinforcement of crural closure with synthetic resorbable mesh has been proposed to decrease recurrence rates after hiatal hernia repair, but continues to be controversial. This systematic review aims to evaluate the safety, efficacy, and intermediate-term results of using biosynthetic mesh to augment the hiatus.

METHODS:

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed throughout this systematic review. The Risk of Bias in Non-Randomized Studies of Interventions and Risk of Bias in Randomized Trials tools were used to perform qualitative assessment of all studies included in this review. Recommendations were then summarized for the following pre-defined key items: protocol, research question, search strategy, study eligibility, data extraction, study design, risk of bias, publication bias, and statistical analysis.

RESULTS:

The systematic literature search found 520 articles, 101 of which were duplicates and 355 articles were determined to be unrelated to our study and excluded. The full text of the remaining 64 articles was thoroughly assessed. A total of 18 articles (1846 patients) were ultimately included for this review, describing hiatal hernia repair using three different biosynthetic meshes-BIO-A, Phasix ST, and polyglactin mesh. Mean operative time varied from 127 to 223 min. Mean follow up varied from 12 to 54 months. There were no mesh erosions or explants. One mesh-related complication of stenosis requiring reoperation was reported with BIO-A. Studies showed significant improvement in symptom and quality-of-life scores, as well as satisfaction with surgery. Recurrence was reported as radiologic or clinical recurrence. Overall, recurrence rate varied from 0.9 to 25%.

CONCLUSION:

The use of biosynthetic mesh is safe and effective for hiatal hernia repair with low complications rates and high symptom resolution. The reported recurrence rates are highly variable due to significant heterogeneity in defining and evaluating recurrences. Further randomized controlled trials with larger samples and long-term follow-up should be performed to better analyze outcomes and recurrence rates.
