Reoperation following urgent and emergent colectomy in the State of Michigan

Background: Reoperation is associated with unfavorable outcomes and increased healthcare utilization. This study seeks to investigate the incidence and factors related to reoperation in patients undergoing urgent/emergent colectomies. Methods: The Michigan Surgical Quality Collaborative (MSQC) database was used to identify patients undergoing urgent/emergent colectomies. Outcomes and risk factors of patients who underwent reoperation within 30 days were compared to those who did not. Results: 16,004 patients undergoing urgent/emergent colon resection were identified. Reoperation occurred in 12.4% and was associated with increased 30-day mortality (16.7% vs. 9.6%, p < .0001), median hospital length of stay (17 vs. 10 days, p < .0001), readmission rate (21.0% vs. 12.1%, p < .001), and discharge to a location other than home (62.3% vs. 36.8%, p < .0001). Reoperation rate was highest for vascular-related indications (23.5%), and was associated with several clinical factors (male gender, low albumin, ASA classification, and presence of pre-operative sepsis, dialysis or ventilator dependence) Conclusions: Reoperation following urgent/emergent colectomy occurs frequently. Additional study into strategies to reduce reoperations in this population is warranted.
