Abstract
Objective
Enhanced Recovery ERP protocols (ERP) have improved surgical outcomes in patients undergoing elective colon cancer (CC) surgery; however, efficacy in different populations may vary. We examined the impact of an ERP in a population with high rates of obesity and multiple comorbidities.
Methods
We performed a retrospective analysis of factors associated with postoperative complications (PoC) and length of stay (LOS) following CC surgery from 2011 to 2019 in a 5-hospital healthcare system which serves a population with higher rates of obesity (body mass index ≥30kg/m2) and multi-comorbidities, as compared to published studies. Univariable and multivariable analyses were performed.
Results
A total of 408 elective CC surgery patients with complete oncologic surgical data were identified. Of these, 191 (46.81%) were under ERP. Factors independently associated with PoC included obesity (OR=1.66, P=.029), laparoscopic (OR=.52, P=.020), and hybrid (OR=.38, P=.012) versus open surgery and ASA (American Society of Anesthesiologists) class ≥3 (OR=1.98, P=.006). ERP did not impact PoC but was associated with a reduction in LOS (β=−1.02 days, 95%CI: −1.75 – -.30, P=.006). ERP had an impact on LOS in both the non-obese and obese groups (P<.001 and P=.034, respectively). PoC significantly increased LOS (β=6.67 days, 95%CI: 5.41-7.03, P<.001).
Conclusions
Following elective CC surgery, obesity and medical comorbidities were associated with increased PoC and in turn, as expected, increased LOS. ERP was associated with a reduction in LOS in both obese and non-obese patients. In high-risk populations, application of ERP may be particularly important to optimize surgical outcomes following CC surgery.
