The Visu-Loc spring clip is being used to occlude the cystic duct at the time of laparoscopic cholecystectomy. A HIDA scan will be completed on post operative day one to check for biliary leaks.

Null hypothesis: There is no difference in subclinical or clinical leak rate between spring and crush clips used for cystic duct ligation.

Alternative hypothesis: Titanium spring clips decrease the rate of subclinical or clinical biliary leak from the cystic duct stump after laparoscopic cholecystectomy.
