BackgroundPlacement of paraesophageal type of "mesh" in paraesophageal hernia repair is controversial. This study examines the trends and outcomes of mesh placement in paraesophageal hernia repair.MethodsThe American College of Surgeons National Surgical Quality Improvement Program was queried for patients who underwent paraesophageal hernia repair with or without mesh (2010-2017). Demographics, operative approach, and outcomes were compared over time.ResultsOf 25,801, most paraesophageal hernia repair cases were elective (89.3%), without mesh (61.9%), and performed laparoscopically (91.3%).When compared with open paraesophageal hernia repair patients, the patients undergoing laparoscopic paraesophageal hernia repair had lesser rates of reoperation, readmission, mortality, overall complications and major complications (2.7% vs 4.8%, 6.2% vs 9.6%, 0.6% vs 2.9%, 7.1% vs 21.3%, 3.8% vs 11.1%, respectively; all P < .0001). Mesh placement was more common in laparoscopic paraesophageal hernia repair (38.9 vs 29.7, P < .0001) than opern paraesophageal hernia repair. During 2010-2017, mesh placement decreased from 46.2% to 35.2% of laparoscopic paraesophageal hernia repair (P < .0001). Operative times for laparoscopic paraesophageal hernia repair decreased over time, and laparoscpic paraesophageal hernia repair without mesh was consistently less (with mesh: 176.0 ± 71.0 to 149.9 ± 72.5 min, without mesh: 148.6 ± 71.4 to 134.6 ± 70.4). We observed no changes in comorbidities or adverse outcomes over time. Using multivariate analysis to control for potential confounding factors, chronic obstructive pulmonary disease was associated most strongly with adverse outcomes, including mortality (OR 2.53, CI 1.55-4.14), any complications (OR 1.80, CI 1.51-2.16), major complications (OR 1.80, CI 1.51-2.16), readmission (OR 1.63, CI 1.33-1.99) and reoperation (OR 1.49, CI 1.10-2.02). Mesh placement was not associated with adverse outcomes.ConclusionThe placement of mesh during laparoscopic paraesophageal hernia repair is not associated with adverse outcomes. Use of mesh with laparoscopic paraesophageal hernia repair is decreasing with no apparent adverse impact on short-term patient outcomes. Further research is needed to investigate patient factors not captured by this national database, such as characteristics of the hernia, patient symptoms, and hernia recurrence.Copyright © 2019 Elsevier Inc.
