Can Preoperative Characteristics Predict the Outcomes of Laparoscopic Cholecystectomy?

Intraoperative findings during laparoscopic cholecystectomy (LC) are highly unpredictable and operative difficulty varies from straightforward to very challenging procedures. Several studies described predictors of technical difficulty and graded intraoperative findings of LC; however, none specifically reported on the effect of such factors on clinical outcomes. This study aims to evaluate if preoperative characteristics of patients undergoing LC predict how likely they are to fail to be day case (DC). Data of patients who underwent LC from 2015 to 2017 were retrospectively analyzed. Subjects were divided into four groups, according to Nassar's classification of intraoperative difficulty. Differences in frequencies were evaluated with the the chi square and chi square tests or Fisher's exact test; logistic regression analysis was used to identify independent variables that were predictors of intraoperative complexity, postoperative morbidity, and length of stay. A total of 1043 patient were included with male to female ratio of 1:2.5. Older age, male gender, and comorbidities were associated with higher Nassar score (
