Risk stratification for complications of laparoscopic cholecystectomy based on associations with sociodemographic and clinical variables in a public hospital
2019
Abstract Background Cholelithiasis is the most common disease of the biliary tract. We aimed to associate complications resulting from laparoscopic cholecystectomy with patients’ sociodemographic and clinical data, stratifying risk based on this association. Methods We retrospectively reviewed the medical records of 2520 patients undergoing laparoscopic cholecystectomy from January 2013 to March 2017 at our institution. Sociodemographic, clinical, and surgical complication data were collected. Unadjusted and adjusted logistic regression models were used to determine independent factors associated with the outcomes of interest. Based on the results, we proposed a risk stratification model, a treatment flowchart, and a severity score. Results Mean age was 48.9 years; 83.53% were female. Intraoperative complications occurred in 206 (8.17%) patients, and postoperative complications in 54 (2.14%). Male sex, older age, diabetes, multiple previous operations, and urgent surgery (odds ratio = 23.77) were significantly associated with surgical complications in both unadjusted and adjusted models. Conclusions We could propose a flowchart based on our risk stratification model and develop a severity score based on the association between complications of laparoscopic cholecystectomy and sociodemographic/clinical data.
