Abstract
Aim
Postoperative 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.
Methods
This 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.
Results
The 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.
Conclusion
Our 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.
