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

Condition or disease Intervention/treatment Phase
Healthy Device: 5mm spring clip Not Applicable

Detailed Description:

The purpose of this study is to evaluate how effective the Visu-Lock clip is at preventing leakage of bile (liquid made by liver and stored in gall bladder) after gallbladder surgery. It is not known if the Visu-Lock clip stops leaks better than other clips that have been used during gallbladder surgery.

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.
