Summary Recurrence after laparoscopic hiatus hernia repair (LHR) is high, with few symptomatic patients undergoing redo LHR. Morbidity is higher in redo surgery compared with the primary operation. Tens of studies have explored the safety of redoing LHR. However, the impact of existing mesh on operative risk is rarely examined. We aim to assess the impact of mesh at the hiatus on the safety of redo LHR. This was a cohort study examining redo LHR patients from a prospectively maintained database from January 2002 to December 2023. The primary outcome was intra-/postoperative complications. Follow-up was extracted from clinical records. Predictors of complications were assessed using univariable and multivariable logistic regression analyses. Redo LHR was performed in 100 patients; 22 had previous mesh. One encountered mortality with 23 complications. Five patients had absorbable mesh, with the remainder nonabsorbable. Overall complications were significantly higher with mesh at nine (40.9%) compared to no mesh redo at 14 (17.9%), P = 0.023. There was no difference in rates of visceral injury with mesh at four (18.2%) and no mesh at six (7.7%), P = 0.22. The median follow-up was 7 months; there was no difference in reflux rates (P = 0.70) but higher rates of dysphagia (P = 0.010). Higher overall complications were noted in patients with previous hiatal mesh repair at the time of LHR. However, major visceral complications were similar regardless of mesh use. Mesh at the hiatus should not be a deterrent for reoperative hiatus surgery.
