Paraesophageal Hernia: To Mesh or Not to Mesh? The Controversy Continues

Abstract

Introduction:

Paraesophageal hernias represent 5%–10% of all primary hiatal hernias and are becoming increasingly more common with the aging of the population. Surgical treatment includes closure of the wide hiatal gap. Achieving tension-free closure is difficult, and several studies have reported lower recurrence rates with the use of mesh reinforcement. The use of this technique, however, is controversial.

Objective and Materials and Methods:

Narrative revision of the literature revising: (1) evidence-based surgery and clinical studies, (2) what the experts say (Delphi), (3) complications of mesh, and (4) long-term results of laparoscopic treatment impact on the quality of life.

Results:

Consensus about the type of mesh continues to be elusive, and we clearly need a higher level of evidence to address the controversy.

Conclusion:

Mesh reinforcement can effectively reduce the hernia recurrence rate. Mesh-associated complications are few, but because they are serious, most experts recommend mesh use only in specific circumstances, particularly those in relation to the size of the hiatal defect and the quality of the crura.
