Patient reported outcomes and decision regret scores in redo-paraesophageal hernia repair

Introduction: Recurrent paraesophageal hernia (PEH) repair presents significant technical challenges, with limited data weighing the benefit to the operative risk. This study aims to describe our experience with recurrent PEH repair, including long-term surgical and patient reported outcomes (PROs).

Methods: We conducted a retrospective review of recurrent PEH repairs from June 2018-March 2023 using our institutional database. A blinded review of post-operative imaging was conducted to assess for recurrence. Quality of life (QOL) and decision regret were measured using the GERD Health-Related Quality-of-Life (GERD-HRQL) questionnaire and Decision Regret Scale (DRS) at maximum follow up.

Results: Eighty-eight patients underwent recurrent PEH repair at our institution for PEH, classified as type II (13.6%), type III (72.7%) and type IV (13.6%). There was significant heterogeneity in operative techniques used: one-third of patients had mesh placed at the hiatus, 11.4% had a Collis gastroplasty, and one-third of patients underwent fundoplication. Intraoperative complications included gastric (5.7%), esophageal (2.3%), vascular (1.1%) and pulmonary (1.1%) injuries. Follow up was available for 73 patients with median follow up of 35.2 months. Of patients with radiographic follow up, 20 (35.7%) had a radiographic recurrence: 12 (21.4%) were 2-5 cm and 8 (14.3%) were > 5 cm. Patients reporting PROs (53 patients; 60.2%) reported low symptom severity (mean GERD-HRQL 13.1 ± 12) and low decision regret (mean DRS 13.3 ± 19.4) with 75.5% scoring in the lowest quartile (DRS < 25). Radiographic recurrence was associated with worse QOL (p < 0.05), but no significant difference in decision regret (p = 0.125).

Conclusion: We found significant heterogeneity amongst recurrent PEH repair techniques with continued high recurrence rate during follow up. Radiographic recurrence was correlated with worse QOL, yet patients reported low symptom severity and low decision regret, suggesting continued value in these challenging operations. Future studies should aim to identify more effective techniques to reduce recurrence rates in this patient population.
