Laparoscopic cholecytectomy can be by starting the dissection at the triangle of calots or as a fundus first dissection.

Dissection can be with electrocutery or ultrasonic. The optimal technique or the optimal way of dissection has to be established. Patients are at 4 hospitals randomised to the different techniques and the different methods of dissection.
