AimPostoperative ileus (POI) is a common complication after abdominal surgery. However, the risk factors for POI after laparoscopic colorectal resection are unclear. We therefore investigated the risk factors for POI after laparoscopic colorectal surgery.MethodsThis retrospective study involved 484 patients who underwent laparoscopic surgery for primary colorectal cancer at Hokkaido University Hospital. We categorized the patients into a POI group (n = 19) and non‐POI group (n = 465). We compared sex, age, smoking, chronic obstructive pulmonary disease (COPD), diabetes mellitus, body mass index (BMI), cardiac disorder, serum albumin, American Society of Anesthesiologists‐physical status, tumor location, tumor stage, operative duration, stoma formation, lymph node dissection, operator, and bleeding as potential risk factors for POI between the POI group and non‐POI group by univariate and multivariate analyses.ResultsThe univariate analysis results showed that the POI group had a higher incidence of male sex (P = 0.036), COPD (P = 0.029), and a BMI of <20 kg/m2 (P = 0.0487) as well as a higher bleeding volume (P = 0.014). The multivariate analysis results showed that male sex (odds ratio [OR], 0.2799; 95% confidence interval [CI], 0.089–0.993; P = 0.0298), COPD (0.2866; 0.095–0.862; P = 0.0262), and a BMI of <20 kg/m2 (0.2985; 0.112–0.794; P = 0.0154) were independent risk factors for POI after laparoscopic colorectal resection.ConclusionOur findings suggest that male sex, COPD, and a BMI of <20 kg/m2 are independent risk factors for POI after laparoscopic colorectal surgery for treatment of colorectal cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
