Secondary Outcome Measures

Name	Time	Method
opinion of operating surgeon in form of survey (score 1-10)<br>-Do you think 3D system improve your operation?<br>-Do you think 3D system is easy to handle?<br>-How do you rate the quality of 3D image?<br>-How do you rate the depth perception of the 3D image<br>-Do you get dizzy with 3D images?<br>-Do you find the 3D dual channel endoscope user-friendly?<br>-Do you prefer to work with 3D system in the future?[review immediately after procedure (skill board and lap cholecystectomy)]
