[Technical standards in surgical procedures]

Laparoscopic cholecystectomy is the "gold standard" for treatment of symptomatic cholelithiasis. Trocar placement and position of the operating team depend from the chosen patient positioning (French/American). After testing the technical equipment, the pneumoperitoneum is established, a 10 mm camera trocar is inserted in the umbilicus, the peritoneal cavity is explored, tension to Calot's triangle is applied, blunt dissection of d. cyst and a. cyst with exposition of the common bile duct, clipping, selective use of cholangiography, retrograde removal of the gallbladder.
