| Interventions |
Participants were randomly assigned to two groups.
Group 1: day‐case laparoscopic cholecystectomy (n = 34).
Group 2: overnight stay laparoscopic cholecystectomy (n = 39).
Participants in the day‐surgery group were admitted to the outpatient surgery department in the morning on the day of surgery and laparoscopic cholecystectomy (LC) was performed before 11:00 a.m. Participants were discharged when they were able to meet standard discharge criteria (adequate pain control: visual analogue scores (VAS) < 4), able to walk, and able to void and tolerate oral liquids. |
