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 2017â¯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 ratioâ¯=â¯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.
