During liver surgery (hepatectomy), surgeons often temporarily clamp the blood vessels supplying the liver to maintain a clear surgical field and reduce bleeding. This common technique is known as the Pringle maneuver. However, this maneuver also temporarily cuts off the blood supply to the gallbladder. Currently, doctors debate whether to routinely remove a healthy gallbladder during liver surgery to prevent future gallbladder problems, or to preserve it.\n\nThe primary purpose of this multicenter retrospective cohort study is to evaluate whether using the Pringle maneuver during liver surgery increases the risk of patients developing gallbladder diseases (such as gallstones or inflammation) later on. Researchers will review the past medical records of patients who underwent liver surgery with their gallbladder preserved between January 2012 and January 2022. By comparing patients who had the Pringle maneuver with those who did not, the study aims to provide reliable clinical evidence to help surgeons make better decisions about whether to preserve or remove the gallbladder during liver surgery.",[174,175],"Gallbladder Diseases","Cholelithiasis",[20,177,24],"Hepatectomy","2026-03-01",{"date":180,"type":181},"2026-03-05","ACTUAL",{"date":178,"type":170},{"date":184,"type":170},"2026-08",{"name":5,"class":6},8]
