After the introduction of the revolutionary laparoscopic methods in the early 90s, cholecystectomy data radically changed. In this method, a laparoscope (a small telescope connected to a specialized camera) is introduced through a 5-10mm diameter tube, and permits to the surgeon to visualize patients  internal organs 10 to 15 times larger than their real dimensions.  At the same time, two or three 3-5mm diameter tubes are also inserted through the abdominal wall and permit to the surgeon to operate in the abdominal cavity.  If according to the surgeons judgement an intraoperative cholangiography or common bile duct exploration (choledochoscopy) will be needed, this can be established throught the same incisions.
