Background:
Parastomal hernia repair is technically complex and associated with substantial morbidity, yet disparities in outcomes among racial groups have not been evaluated. Identifying inequalities in this population may inform strategies to improve access and perioperative care.
Methods:
The ACS-NSQIP database from 2013 to 2023 was queried for adults undergoing parastomal hernia repair. Demographics, comorbidities, and operative details were compared among White patients, Black patients, and Hispanic patients. Primary outcomes included 30-day morbidity, infectious complications, and length of stay (LOS). Multivariable logistic and linear regression models were performed using a two step forward selection model adjusting for comorbidities and surgical details.
Results:
A total of 3,513 patients were included (White 85, Black 8, Hispanic 7%). Black patients had higher unadjusted rates of morbidity (38 vs 30 White, 32% Hispanic; p = 0.023), serious complications (20 vs 13% white vs 13% Hispanic, p = 0.008), infectious complications (20 vs 13 White, 15% Hispanic; p = 0.004), and longer median LOS (6 vs 5 days White, 6 days Hispanic; p = 0.005). On multivariable analysis, Black race remained independently associated with increased odds of overall morbidity (aOR 1.31, 95% CI 1.01-1.70; p = 0.043), serious complications (aOR 1.65; CI 1.15-2.34, p = 0.006), and infectious complications (OR 1.44, 95% CI 1.04-1.98, p = 0.026) compared to white patients.
Conclusion:
This is the first national study to characterize racial disparities in parastomal hernia repair. Black patients experienced higher morbidity, infectious complications, and length of stay compared to White patients, while Hispanic patients did not differ from White patients. Disparities were emphasized in emergent cases, suggesting that barriers to timely elective repair possible drive imbalances in parastomal hernia repair, warranting interventions for underserved populations, with early referral, equal access, and tailored perioperative support.
