Normal preoperative levels of gamma-glutamyltransferase predict the absence of common bile duct stones in patients scheduled for laparoscopic cholecystectomy: a retrospective cohort study.

Unlabelled: Laparoscopic cholecystectomy, nowadays, is considered the gold standard option for management in patients diagnosed with symptomatic cholelithiasis. Nevertheless, some patients may have coexisting choledocholithiasis, which manifests later in life with grave complications such as cholangitis and pancreatitis. The objective of this study is to evaluate the role of preoperative gamma-glutamyltransferase (GGT) in predicting choledocholithiasis in patients undergoing laparoscopic cholecystectomy.
