Background:
Revisional antireflux surgery, including hiatus hernia repair, is increasingly common. Mesh-augmented hiatal closure at the time of index operation is controversial but commonly performed. Although a meta-analysis of randomized data has demonstrated no additional benefit of routine mesh placement, it is unclear whether this practice results in harm, particularly at the time of revisional antireflux surgery. We determined whether pre-existing mesh at the hiatus increases morbidity during and after revisional antireflux surgery.
Methods:
Analysis of prospectively-maintained databases of all elective revisional antireflux surgery cases in 36 hospitals across Australia took place over 10 years. Intraoperative and postoperative outcomes of patients with and without prior hiatal mesh were compared. Propensity score-matched analysis was used to validate primary findings.
Results:
A total of 346 revisional cases (35 with pre-existing mesh) were analyzed. The 2 groups had comparable baseline characteristics. In total, 77 (22.2%) patients had 148 intraoperative adverse events. Pre-existing mesh was associated with a higher risk of intraoperative complications (48.6% vs 22.5%, odds ratio 3.25, 95% confidence interval 1.63-6.38, P = .002), secondary to bleeding, and lacerations to pleura, lung, and liver. Overall, 63 (18.2%) patients developed postoperative complications. Pre-existing mesh was associated with increased postoperative morbidity (37.1% vs 16.1%, odds ratio 3.09, 95% confidence interval 1.50-6.43, P = .005), particularly due to bleeding and respiratory complications. Importantly, pre-existing mesh independently predicted the occurrence of intraoperative and postoperative complications.
Conclusion:
Prior hiatal mesh significantly increases morbidity during and after revisional antireflux surgery. Given that revisional surgery is increasingly being performed, our findings discourage routine mesh use during primary antireflux surgery.
