Abstract: Objective To determine the incidence and risk factors of prolonged postoperative ileus (PPOI) after major abdominal surgery in our hospital. Methods From July 2016 to December 2017, 123 patients who underwent radical operation of open digestive tract tumor were enrolled in the general surgery department of Beijing Friendship Hospital, Capital Medical University. Patients with PPOI were set as the case group (13 cases), otherwise it was the control group (110 cases). Univariate and multivariate logistic regression models were used to analyze the risk factors of PPOI. Results Univariate analysis showed that body mass index (BMI) <18.5 kg/m2 (χ2=6.824, P=0.009) and postoperative hypokalemia (χ2=3.872, P=0.049) were related to PPOI. Multivariate regression analysis showed that BMI <18.5 kg/m2 was an independent risk factor for PPOI. Conclusion The risk factors of PPOI may include BMI <18.5 kg/m2 and postoperative hypokalemia. According to the chi-square test and logistic regression analysis, BMI is an independent risk factor for PPOI. The patients will be more at risk of PPOI when BMI<18.5 kg/m2.
