Open inguinal hernia repair outcomes in liver transplant recipients versus patients with cirrhosis

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 < 0.001). There were no mortalities among OLT recipients, but 19 (2.5%) deaths among LC patients. OLT recipients had a similar risk of overall complications (adjusted odds ratio aOR = 0.71 1.30 2.41) and hospital-associated costs (adjusted cost ratio = 0.71 0.88 1.09). However, LOS was significantly different with OLT recipients having shorter LOS (adjusted LOS ratio = 0.56 0.70 0.89). Conclusion Delaying OIHR in patients with LC until after OLT decreases LOS and may carry decreased mortality.
