Abstract:

Objective

To analyze the influencing factors of prolonged postoperative ileus (PPOI) in postoperative patients with colorectal cancer.

Methods

The clinical data of 402 patients with colorectal cancer who underwent radical resection in Shanghai Fifth People's Hospital affiliated to Fudan University from January 2017 to December 2021 were analyzed retrospectively. Patients were divided into PPOI group and non-PPOI group according to whether they had prolonged postoperative ileus (PPOI) or not. Univariate analysis was used to compare the differences of different factors between the two groups, and Logistic regression analysis was used to determine the independent risk factors of PPOI.

Results

In univariate analysis, compared with the non-PPOI group, PPOI group had a lower stoma ratio (χ2=9.419, P<0.05), a higher postoperative hypoalbuminemia ratio (χ2=-2.299, P<0.05) and a higher postoperative hypokalemia ratio (χ2=-8.516, P<0.05). The CRP value on the first day after operation was high (t=4.967, P<0.05), the proportion of diabetes mellitus was high (χ2=17.074, P<0.05). The results of multivariate analysis suggest that postoperative CRP increase, diabetes mellitus and hypoproteinemia are independent risk factors for PPOI. Stoma is a protective factor of PPOI independence.

Conclusion

Patients with colorectal cancer complicated with diabetes, low albumin and elevated CRP after operation have an increased risk of PPOI. Colostomy can reduce the occurrence of PPOI.
