â¢Predicting surgical duration is important for OR scheduling and utilization.â¢Patient factors can aid in scheduling of laparoscopic cholecystectomies (LC).â¢BMI, age, gender, ASA, and LFT are significant predictors of LC >60 minutes.
BackgroundPatient factors impact laparoscopic cholecystectomy (LC) difficulty, specifically operative duration. This study quantifies the impact of patient factors on LC duration.MethodsThe national surgery database (American College of Surgeons National Surgical Quality Improvement Program) was reviewed for all elective LC for biliary colic from 2005 to 2013. Multivariate general linear model and logistic regression were used to evaluate patient factors as predictors of operative duration greater than 60Â minutes, adjusted for resident involvement and cholangiography.ResultsA total of 24,099 LC met inclusion criteria. Regression analysis found procedure duration greater than 60Â minutes was less likely for patients age greater than 40 and less than 30 (PÂ < .001) and more likely for men (P < .05), body mass index (BMI) greater than 30 compared with BMI 18.5 to 24.9 (P < .05), abnormal liver function test (LFT) (P < .05), and higher ASA class (PÂ <Â .05). Smoking, cardiovascular disease, chronic obstructive pulmonary disease, diabetes, and abnormal white blood cell count were not significant predictors.ConclusionsHigher BMI, younger age, male gender, higher ASA, and abnormal LFTs are possible predictors of prolonged LC duration and can aid in operating room scheduling and utilization.
