BackgroundAs the life expectancy in the United States continues to increase, more elderly, sometimes frail patients present with sub-acute surgical conditions such as a symptomatic paraesophageal hernia (PEH). While the outcomes of PEH repair have improved largely due to the proliferation of laparoscopic surgery, there is still a defined rate of morbidity and mortality. We sought to characterize the outcomes of both elective and emergent PEH repair using a large population-based data set.MethodsThe Nationwide Inpatient Sample was queried for primary ICD-9 codes associated with PEH repair (years 2006-2008). Outcomes were in-hospital mortality and the occurrence of a pre-identified complication. Multivariate analysis was performed to determine the risk factors for complications and mortality following both elective and emergent PEH repair.ResultsA total of 8,462 records in the data, representing 41,723 patients in the US undergoing PEH repair in the study interval, were identified. Of these procedures, 74.2% was elective and 42.4% was laparoscopic. The overall complication and mortality rates were 20.8 and 1.1%, respectively. Emergent repair was associated with a higher rate of morbidity (33.4 vs. 16.5%, p < 0.001) and mortality (3.2 vs. 0.37%, p < 0.001) than elective repair. Emergent repair patients were more likely to be male, were older, and more likely to be minority. Logistic modeling revealed that younger age, elective case status, and a laparoscopic approach were independently associated with a lower probability of complications and mortality.ConclusionsPatients undergoing emergent PEH repair in the United States tend to be older, more likely a racial minority, and less likely to undergo laparoscopic repair. Elective repair, younger age, and a laparoscopic approach are associated with improved outcomes. Considering all of the above, we recommend that patients consider elective repair with a surgeon experienced in the laparoscopic approach, especially when symptoms related to the hernia are present.
