The aim of this study is to compare 3D-laparoscopy versus 2D-laparoscopy with the use of HD resolution in cholecystectomy in terms of error rating, performance time and subjective assessment.
Conventional laparoscopy can be very challenging, especially with the requirement of converting the two-dimensional image of the operating field to a three-dimensional perception. This can potentially lead to a detrimental effect on the learning curve as well for the feasibility of the operation for the more inexperienced surgeon. In our hospital, the high frequency of cholecystectomy serves as a basis for the minimally experienced surgeons to explore whether three-dimensional laparoscopy provides a better ability for solving complex intraoperative tasks than the conventional laparoscopy.

RECRUITINGNumber of errors during the dissection of the Calot´s triangle
The unedited videos of the operations will be assessed according to GERT (Generic Error Rating Tool) by three surgeons, blinded to which optical modalities is used during the operations as done in a previous pilot study.
Time frame: Expected duration: 20 minutes
Duration of the dissection of the Calot´s triangle
Time frame: Expected duration: 20 minutes
Duration of surgery
Time frame: Expected duration: 1 hour
The need for conversion to open surgery
Time frame: intraoperative, expected duration of surgery: 1 hour
Estimated blood loss in ml
Time frame: intraoperative, expected duration of surgery: 1 hour
Intraoperative complications
e.g. leakage of bile, leakage of gallstone, injury to the bile ducts, injury to organs.

Subjective assessment (Assessment of fatigue and perceived exertion)
The surgeon will fill out questionnaires and scales.
Time frame: an expected average of 15 minutes before and after the operation
Subjective assessment (optical modality and mental load assessment)
The surgeon will fill out questionnaires and scales.
Time frame: an expected average of 15 minutes after the operation
