Analysis of risk factors related to anastomotic leakage after rectal cancer surgery / 中国现代医生

ABSTRACT

Objective To investigate the risk factors related to postoperative anastomotic leakage(AL)of rectal cancer.Methods The clinical data of 392 patients with rectal cancer diagnosed and treated in Linyi People's Hospital from January 2019 to December 2021 were retrospectively analyzed.They were divided into AL group(n=17)and non-AL group(n=375)according to whether AL occurred.The relevant clinical data of patients were collected,and the risk factors of postoperative AL in rectal cancer patients were analyzed by binary Logistic regression.Results The proportion of body mass index(BMI)≥25kg/m2,preoperative intestinal obstruction,perioperative blood transfusion history,operation duration≥3h and postoperative white blood cell count≥10×109/L in AL group were significantly higher than those in non-AL group(P<0.05).Binary Logistic regression analysis showed that BMI≥25kg/m2,preoperative intestinal obstruction,and operation duration≥3h were all independent risk factors for postoperative AL in rectal cancer patients(P<0.05).Conclusion Patients with rectal cancer who are obese,have preoperative intestinal obstruction,and have long operation duration have a higher risk of postoperative AL.Corresponding preventive measures should be taken according to the above risk factors to reduce the incidence of AL and improve the quality of life of patients.
