Objective The aim of this study is to investigate whether origins of ethnicity affect the outcomes of surgery for diverticulitis in the USA. Design The American College of Surgeons National Surgical Quality Improvement Programme database from 2008 to 2017 was used to identify patients undergoing colectomy for diverticulitis. Patient demographics, comorbidities, procedural details and outcomes were captured and compared by ethnicity status. Results A total of 375 311 surgeries for diverticulitis were included in the final analysis. The average age of patients undergoing surgery for diverticulitis remained consistent over the time frame of the study (62 years), although the percentage of younger patients (age 18–39 years) rose slightly from 7.8% in 2008 to 8.6% in 2017. The percentage of surgical patients with Hispanic ethnicity increased from 3.7% in 2008 to 6.6% of patients in 2017. Hispanic patients were younger than their non-Hispanic counterparts (57 years vs 62 years, p<0.01) at time of surgery. There were statistically significant differences in the proportion of laparoscopic cases (51% vs 49%, p<0.01), elective cases (62% vs 66%, p<0.01) and the unadjusted rate of postoperative mortality (2.8% vs 3.4%, p<0.01) between Hispanic patients compared with non-Hispanic patients, respectively. Multivariable logistic regression models did not identify Hispanic ethnicity as a significant predictor for increased morbidity (p=0.13) or mortality (p=0.80). Conclusion Despite a significant younger population undergoing surgery for diverticulitis, Hispanic ethnicity was not associated with increased rates of emergent surgery, open surgery or postoperative complications compared with a similar non-Hispanic population. Data may be obtained from a third party and are not publicly available. All of our data were obtained from the National Surgical Quality Improvement Program database. It is only available for participating hospitals.

西班牙裔种族对美国憩室手术的结果有影响吗？

目的 本研究的目的是调查种族起源是否影响美国憩室炎手术的结果。设计 美国外科医生学会 2008 年至 2017 年国家手术质量改进计划数据库用于识别因憩室炎而接受结肠切除术的患者。患者的人口统计数据、合并症、手术细节和结果均按种族状况进行记录和比较。结果最终分析憩室炎手术375 311例。尽管年轻患者（18-39 岁）的比例从 2008 年的 7.8% 略有上升至 2017 年的 8.6%，但接受憩室炎手术的患者的平均年龄在研究期间保持一致（62 岁）。西班牙裔手术患者的比例从 2008 年的 3.7% 增加到 2017 年的 6.6%。手术时，西班牙裔患者比非西班牙裔患者年轻（57 岁 vs 62 岁，p<0.01）。腹腔镜病例比例（51% vs 49%，p<0.01）、择期病例比例（62% vs 66%，p<0.01）以及未经调整的术后死亡率（2.8% vs 3.4%，p<0.01）差异有统计学意义。西班牙裔患者与非西班牙裔患者之间的差异分别为 p<0.01。多变量逻辑回归模型并未将西班牙裔种族视为发病率 (p=0.13) 或死亡率 (p=0.80) 增加的显着预测因素。结论 尽管接受憩室炎手术的人群显着年轻化，但与类似的非西班牙裔人群相比，西班牙裔种族与急诊手术、开放手术或术后并发症发生率增加无关。数据可能从第三方获得，并且不公开。我们所有的数据均来自国家手术质量改进计划数据库。仅适用于参与的医院。
