Abstract
Objective: To analyze the risk factors of postoperative intestinal obstruction (POI) in patients undergoing robot-assisted laparoscopic radical prostatectomy (RARP). Methods: The clinical data of 573 patients receiving RARP from January to December 2019 in Nanjing Drum Tower Hospital were analyzed retrospectively. According to the occurrence of POI, the cases were divided into the occurrence group and the non-occurrence group. The clinical data of the two groups were compared and the risk factors of POI were investigated by multivariate logistic regression. Results: Forty-five of 573 patients (7.9%) had POI. Between the two groups, preoperative underlying diseases (cardiopathy, COPD, hypoalbuminemia), preoperative chemotherapy, preoperative WBC, operation time, blood loss, blood transfusion rate, postoperative early fever, length of stay were statistically significant (P<0.05). Multivariable logistic regression analysis showed that heart disease (OR=2.331, P=0.036), COPD (OR=4.285, P=0.001), hypoalbuminemia(OR=2.142, P=0.026), blood loss (≥4.26 ml/kg) (OR=2.388, P=0.010), operative time (≥225 min) (OR=4.200, P<0.001), and postoperative early fever (OR=2.773, P=0.004) were independent risk factors for POI after RARP. Conclusions: The incidence of POI following RARP is related to multiple perioperative factors. Improving the preoperative heart and lung function, correcting hypoalbuminemia, reducing intraoperative bleeding, shortening the operation time, and preventing early postoperative infection may be important measures to reduce the risk of POI in RARP patients.
