Emergency surgery for hiatus hernias: does technique affect outcomes? A single-centre experience.

BACKGROUND: Emergency surgery for a hiatus hernia is usually a high-risk procedure in acutely unwell patients. Common surgical techniques include reduction of the hernia, cruropexy then either fundoplication or gastropexy with a gastrostomy. This is an observational study in a tertiary referral centre for complicated hiatus hernias to compare recurrence rates between these two techniques.

METHODS: Eighty patients are included in this study, from October 2012 to November 2020. This is a retrospective review and analysis of their management and follow-up. Recurrence of the hiatus hernia that mandates surgical repair was the primary outcome of this study. Secondary outcomes include morbidity and mortality.

RESULTS: In total, 38% of the patients included in the study had fundoplication procedures, 53% had gastropexy, 6% had complete or partial resection of the stomach, 3% had fundoplication and gastropexy and one patient had neither (n = 30, 42, 5, 2,1, respectively). Eight patients had symptomatic recurrence of the hernia which required surgical repair. Three of these patients had acute recurrence and 5 after discharge. 50% had undergone fundoplication, 38% underwent gastropexy and 13% underwent a resection (n = 4, 3, 1) (p value = 0.5). 38% of patient had no complications and 30-day mortality was 7.5% CONCLUSION: To our knowledge, this is the largest single centre review of outcomes following emergency hiatus hernia repairs. Our results show that either fundoplication or gastropexy can be used safely to reduce the risk of recurrence in the emergency setting. Therefore, surgical technique can be tailored based on the patient characteristics and surgeon experience, without compromising the risk of recurrence or post-operative complications. Mortality and morbidity rates were in keeping with previous studies, which is lower than historically documented, with respiratory complications most prevalent. This study shows that emergency repair of hiatus hernias is a safe operation which is often a lifesaving procedure in elderly comorbid patients.
