BN SO53 - Thoracotomy for the Repair of Giant Paraesophageal and Hiatal Hernias: A Systematic Review

Abstract

Abstract Background The utilisation of transthoracic approaches for the repair of large hiatus hernias remains a topic of clinical debate. This study aims to evaluate and compare the efficacy, safety, and recovery metrics for transthoracic hiatal hernia repair and comparisons to the laparoscopic approach. Method A literature search was conducted using the key terms "hiatus hernia," "thoracotomy," "thoracic approach," and "Belsey Mark IV." The databases searched included MEDLINE, EMBASE, and Web of Science, covering the period from 2000 to June 2024. Extracted data included patient demographics, study design characteristics, length of stay, complication rate and mortality rate. Results A total of 5 citations were selected comprising a total of 560 patients of which 164 were male (29.3%) with an overall mean age was 64.9 (pooled SD = 1.93) and weighted mean follow-up length was 56.4 months (pooled SD = 39.1 months). The weighted overall mean length of stay was 14.5 days (Pooled SD = 7.42). The overall rate of minor complications was 19% (95% CI [6%, 31%]). The overall rate of major complications was 13% (95% CI [6%, 21%]). There were 4 reported mortalities in total and an overall leak rate of 1% (95% CI [0%, 2%]). Conclusion Both thoracotomy and laparoscopy have unique benefits and risks in the context of hiatal hernia surgery. Access via thoracotomy is associated with a higher incidence of complications. However, for large or emergent paraesophageal hernias, the transthoracic approach may represent a viable option in select patients.
