A Clinical Risk Analysis of Postoperative Nausea and Vomiting After Colorectal Cancer Surgery

Abstract

Objective Postoperative nausea and vomiting (PONV) is a frequent complication following colorectal surgery. The present study investigated the risk factors for PONV after colorectal cancer surgery. Methods A retrospective study of 204 patients who underwent surgery for colorectal cancer was conducted. Univariate and multivariate analyses were performed to determine the clinicopathological factors associated with PONV. Results The overall incidence of postoperative nausea (PON) and postoperative vomit (POV) was 26.5% (54/204), and 12.3% (25/204), respectively. The univariate analysis showed that female gender (p < 0.001), no current alcohol drinking habit (p = 0.003), and no stoma creation (p = 0.023) were associated with PON. Postoperative vomit was significantly correlated with female gender (p = 0.009), high body mass index (p = 0.017), and right-sided colon cancer (p = 0.001). The multivariate logistic regression analysis revealed that female gender (odds ratio [OR]: 4.225; 95% confidence interval [CI]: 2.170–8.226; p < 0.001) was an independent risk factor for PON. A high body mass index (OR: 1.148; 95%CI: 1.018–1.295; p = 0.025), and right-sided colon cancer (OR: 3.337; 95%CI: 1.287–8.652; p = 0.013) were independent risk factors for POV. Conclusion Our findings suggest that female gender for PON and a high body mass index and right-sided colon cancer for POV are risk factors after colorectal cancer surgery. An assessment using these factors might be helpful for predicting PONV.
