Core Tip

Core tip: The clinical benefits, in terms of efficacy and safety, of performing the additional intraoperative cholangiography (IOC) procedure during laparoscopic cholecystectomy (LC) treatment in patients with symptomatic cholelithiasis are not definitively established. This prospective randomized trial was designed to compare the operative and outcome features of patients treated by routine LC or LC + IOC. No statistically significant benefits were found for rates of common bile duct (CBD) stone retainment, CBD injury or other complications, or length of hospital stay, but the LC + IOC treatment required significantly longer operative time.
