End Stage Renal Disease Is Associated with Increased Mortality in Perforated Gastroduodenal Ulcers

Patients with end stage renal disease (ESRD) represent a growing subset of surgical candidates and ESRD status has been associated with increased morbidity and mortality in other operations. Using a national database, we examined outcomes and risk factors for patients presenting with perforated gastroduodenal ulcers undergoing omentopexy. We identified adult and emergent patients with perforated duodenal and gastroduodenal ulcers that underwent omentopexy using the 2005 to 2012 Nationwide Inpatient Sample. We identified patients with ESRD status and assessed comorbidity status using the Elixhauser-van Walraven score. Univariate and multivariable logistic regression analyses were performed. Inpatient mortality was the primary outcome. Six thousand five hundred and twenty-one patients were identified. Median age was 59.0 years, majority were male (55.56%), 79 (1.21%) patients had ESRD, 367 (5.63%) patients died during admission. Multivariable logistic regression showed age (OR 2.71, P < 0.0001), Elixhauser-van Walraven score (OR 2.69, P < 0.0001), and ESRD status (OR 3.88, P < 0.0001) as independent risk factors for mortality. ESRD was associated with increased mortality in patients undergoing omentopexy for perforated gastroduodenal ulcers. Future studies are necessary to identify methods to increase perioperative survival.
