Access to common laparoscopic general surgical procedures: do racial disparities exist?

backgroundLaparoscopy has become the standard of care for the majority of cases for inguinal hernia repair, cholecystectomy, appendectomy, and colectomy due to the shortened patient recovery time compared to open surgery. This study sought to determine if there exists racial disparity in access to a laparoscopic approach to these common surgeries.

methodsThis was an IRB-approved retrospective study utilizing data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Individuals who underwent inguinal hernia repair, cholecystectomy, appendectomy, and colectomy in 2016 were identified. Information on self-reported race and ethnicity and other demographic and pre-operative clinical covariates were recorded. Propensity matching was conducted to evaluate the association between race and a laparoscopic approach to surgery.

resultsThere were 44,522, 60,444, 50,523, and 58,012 cases of inguinal hernia repair, cholecystectomy, appendectomy, and colectomy identified, respectively. Of these patients, 8.38, 8.76, 6.69, and 9.02% self-identified as black, respectively. Confounding effects of variables other than race were balanced by propensity matching. After propensity matching, there were 7460, 10,574, 10,470, and 6758 cases of hernia repair, cholecystectomy, colectomy, and appendectomy, respectively. On univariate (Chi square) analysis with laparoscopic surgery as the primary outcome, black race was significantly associated with lower likelihood of undergoing a minimally-invasive surgical approach in all four surgical procedures under investigation (33.86% of white patients and 21.69% of black patients, p < 0.0001 for hernia repair; 97.98% of white patients and 94.29%, p < 0.0001 of black patients for cholecystectomy; 70.93% of white patients and 48.60% of black patients, p < 0.0001 for colectomy; and 98.85% of white patients and 92.81% of black patients, p < 0.0001 for appendectomy).

conclusionsThere appears to be a significant racial disparity in the application of a laparoscopic approach to routine intra-abdominal surgery. This warrants further investigation into the barriers preventing access to laparoscopic general surgical procedures that certain populations face.
