  • Rates of successful clearance of the bile duct were the same between groups. Length of stay was significantly shorter for LC+LCBDE performed at night. Data presented as median and IQR.

  • Alk Phos, alkaline phosphatase; ALT, alanine transaminase; AST, aspartate transaminase; BMI, body mass index; LC+LCBDE, laparoscopic cholecystectomy with laparoscopic common bile duct exploration; T Bili, total bilirubin.
