Background
Patients with Barrett’s esophagus (BE) are more likely to have associated hiatal hernia (HH) compared to the general population. Studies show that HH are typically longer and wider in patients with BE.
Aims
To determine whether patients with HH have associated increased odds of coexistence of BE by examining inpatient prevalence, as well as determining other inpatient outcomes.
Methods
This was a case–control study using the NIS 2016, the largest public inpatient database in the USA. All patients with ICD10CM codes for BE were included. None were excluded. The primary outcome was determining the association between BE and HH in hospitalized patients, stratified by grade of dysplasia. Secondary outcomes included measuring use of endoscopic ablation in patients with BE and HH compared to patients with BE and no HH, determining the degree of association between HH and esophagitis in patients with or without BE, as well as the association between esophagitis and dysplasia in patients with BE and HH.
Results
A total of 118,750 patients with BE were identified, of which 24,030 had associated HH. Adjusted odds of having associated BE in patients with HH was 10.9 (p < 0.01) compared to patients without HH. Patients with HH also displayed significantly higher odds of both low-grade dysplasia (aOR 34.5, p < 0.01) and high-grade dysplasia (aOR 14.7, p < 0.01). For secondary outcomes, the odds of undergoing ablation for BE was higher 4.77 (p < 0.01) in patients with HH.
Conclusions
Patients with HH have significantly higher odds of having associated BE, regardless of the level of dysplasia. Furthermore, the odds of undergoing ablation are much higher, likely reflecting higher odds of dysplasia. This highlights the importance of BE in patients with HH, and potentially consider these patients as higher risk.
