**6. Concept of safe cholecystectomy**

Over the years, there have been many methods for reducing the risk of biliary structures injuries while performing cholecystectomy. Fisher's method, in which the surgeon removes the gallbladder from the gallbladder bed and then identifies the cystic artery and cystic duct which are sequentially ligated, is deemed overcome due to 95% penetration of laparoscopy in the gallbladder surgery [12]. The introduction of the Strassberg method in 1995 meant firstly the preparation of cystic artery and cystic duct in a hepatocystic triangle with identification of cystic duct entering the gallbladder infundibulum [20]. This method is currently called the critical view of safety technique (**Figure 4**) [20].
