3D HD Versus 2D HD in Cholecystectomy

Three-dimensional High-definition (3DHD) Laparoscopy Versus Two-dimensional High-definition (2DHD) Laparoscopy in Cholecystectomy: a Clinical Controlled Randomized Double Blinded Trial.

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.

Inclusion Criteria:

• Patients scheduled for elective cholecystectomy (out-patient treatment)
