Analysis of risk factors for surgical site infections after laparoscopic cholecystectomy / 中国实用护理杂志

ABSTRACT

Objective To identify the risk factors for surgical site infections after operation of laparoscopic cholecystectomy (LC), so as to provide warning signs for preventing such incidents. Methods The data of 4042 LC patients from January 2003 to December 2015 were analyzed retrospectively. The risk factors for surgical site infections were identified among demographic data, preoperative patients′history, and operative data using multivariate Logistic regression analysis. Results Surgical site infections after LC was seen in 7.2% (291/4042) of the patients. Multivariate analysis identified the following parameters as risk factors for surgical site infections additional surgical procedure ( OR 4.011, 95%CI 2.149-7.486), age over 55 years (OR 2.398, 95%CI 1.777-3.235), conversion to open procedure (OR 2.647, 95%CI 1.935-3.621), postoperative hematoma (OR 1.910, 95%CI 1.192-3.060), duration of operation >60 min (OR 2.493, 95%CI 1.710-3.635), cystic stump insufficiency (OR 12.451, 95%CI 4.169-37.189), gallbladder perforation (OR 6.161, 95%CI 2.365-16.047), gallbladder empyema (OR 1.704, 95%CI 1.080-2.689), and surgical revision (OR 15.725, 95%CI 10.439-23.686). Surgical site infections were associated with a significantly prolonged hospital stay (P60 min, age >55 years, conversion to open procedure, cystic stump insufficiency, postoperative hematoma, gallbladder perforation, gallbladder empyema, or surgical revision were identified as specific risk factors for surgical site infections after LC.
