Background: Due to the rise in diverticular disease, the ASCRS developed practice parameters to ensure high-quality patient care. Our study aims to evaluate the impact of the 2014 practice parameters on the treatment of non-emergent left-sided diverticular disease.
Methods: This is a retrospective cohort study using the ACS-National Surgical Quality Improvement Project (ACS-NSQIP). Elective sigmoid resections performed by year were evaluated and compared before and after practice parameters were published.
Results: Overall, 46,950 patients met inclusion criteria. There was a significant decrease in the number of non-emergent operations when evaluating before and after guideline implementation (P < .001). There was a significant decrease in the number of patients younger than 50 years of age operated electively for diverticular disease (25.8% vs. 23.9%, P = .005). Adoption of minimally invasive surgery continued to increase significantly throughout the study period.
Conclusions: Publication of the 2014 ASCRS practice parameters is associated with a change in management of diverticular disease in the non-emergent setting.
