Hidden blood loss and the influencing factors after laparoscopic cholecystectomy.

Background: A small amount of bleeding usually occurs during laparoscopic cholecystectomy (LC), but the occurrence of perioperative hidden blood loss (HBL) is ignored. So our objective is to investigate the amount of HBL and find out the influential factors in LC.

Methods: From January 2017 to May 2019, 139 patients scheduled for LC were enrolled in the study.
