Current state of repair of large hiatal hernia

Abstract

Large hiatus hernias are encountered with increasing frequency in aging Western populations. If certain steps are followed, repair can be safely and reliably achieved using laparoscopic approaches. However, surgeons disagree about some key steps, including the use of mesh for repair of the hiatus, lengthening of the esophagus, and the addition of a fundoplication. A narrative review of literature pertinent to laparoscopic repair of large hiatus hernia was undertaken, with priority given to information available from randomized trials. All surgeons agree that the hiatal sac should be fully dissected from the chest to reduce the stomach, and the majority add a fundoplication of some sort. Opinions diverge significantly for the addition of a Collis procedure or the use of mesh. Evidence cited to support these opinions can be prioritized differently by different individuals, and the same evidence is often be cited to support either view. Nevertheless, randomized trials of mesh versus sutured hiatal repair have yielded divergent outcomes, with the more recent studies reporting longer term outcomes failing to support the use of mesh. Surgeons seeking 'anatomical perfection' will often add a Collis procedure and are more likely to use mesh. However, the alternative view is that patient satisfaction with the clinical outcome should be prioritized. When this view is taken, a Collis procedure is rarely required. The author concludes that surgeons should aim to keep this operation simple, and an approach which prioritizes careful dissection to protect hiatal structures, followed by sutured repair will deliver a good clinical outcome for most patients.
