Background:
Hispanic ethnicity is associated with increased incidence of gallbladder disease. Additionally, ethnicity has been shown to be an outcome determinant in several conditions and procedures but has never been studied as a potential determinant of morbidity or mortality after laparoscopic or open cholecystectomy.
Methods:
Using the American College of Surgeons National Surgical Quality Improvement Program database, patients who underwent cholecystectomy and related procedures were studied in Hispanic and non-Hispanic cohorts. Mortality and postoperative complication rates were calculated and adjusted for patient demographics and comorbidities through multivariate analysis.
Results:
Hispanics had decreased morbidity following cholecystectomy as compared to non-Hispanics on univariate analysis in combined, laparoscopic, and open cohorts (RR 0.64, P value < 0.001; 0.68, <0.001; 0.77, <0.001, respectively). The reduction was not found to be statistically significant in multivariate analysis. A similar reduction was seen for mortality (RR 0.30, <0.001; 0.39, <0.001; 0.28, <0.001, respectively) which remained on multivariate analysis in both combined and open cohorts (RR 0.63, 0.008 and 0.48, 0.021, respectively). Additionally, the rates of several postoperative complications were found to be reduced in Hispanic patients. Though our study demonstrates a lower rate of established comorbidities for poor outcomes in Hispanics, after adjustment in multivariate analysis, the entirety of the reduced risk could not be accounted for.
Conclusions:
While the Hispanic cohort has an increased incidence in gallbladder disease as compared to non-Hispanics, the complication, morbidity, and mortality rates are lower in unadjusted analysis. With adjustment, morbidity was not statistically significant and mortality was only significant in combined and open cohorts. This suggests that increased incidence rates do not equate with worse outcomes, but Hispanic ethnicity may be associated with better outcomes.
