Abstract Purpose  Patients with liver cirrhosis (LC) are at an increased risk for postoperative complications after open inguinal hernia repair (OIHR). It is possible that orthotopic liver transplant (OLT) recipients may have better outcomes, given reversal of liver failure pathophysiology. Therefore, we sought to compare mortality risk, complications, length of stay (LOS), and cost associated with OIHR in OLT recipients versus LC. Methods  From the National Inpatient Sample (NIS), using ICD-9 codes, we found 83 OLT recipients and 764 patients with LC who underwent OIHR between 2002 and 2014. We used logistic, negative binomial, and multiple linear regression models to compare peri-operative mortality risk, postoperative complications, and LOS, and cost associated with OIHR in OLT recipients versus LC patients. Models were adjusted for patient demographic and clinical characteristics, and hospital factors. Results  OLT recipients were younger (58 vs 61, p = 0.02), more likely to be privately insured (42.0% vs 24.6%, p = 0.006), less likely to have ascites at time of surgery (5.1% vs 18.9%, p = 0.003), and have surgery at large (84.3% vs 65.2%, p = 0.01) and teaching hospitals (84.2% vs 47.9%, p
