Abstract
Abstract. Aim: to assess the safety of mini-laparoscopic cholecystectomy (MLC) compared to traditional laparoscopic cholecystectomy (LC) based on a critical view of safety (CVS).
 Materials and methods: an analysis of 46 video recordings of MLC surgeries and 156 LC surgeries performed for chronic calculous cholecystitis and gallbladder polyps between 2015 and 2022 was conducted, using the concept of CVS and the quality of its achievement. An analysis of anatomical variations was also performed.
 Results and discussion: the average age was 38.5 years in the MLC group and 53.8 years in the LC group, with an average operation time of (59.4±2.13) minutes and (63.01±2.01) minutes, respectively. CVS was achieved in 97.8 % of cases in MLC and 93.0 % in LC. Anatomical variations were present in 31.1 % of cases in MLC and 30.1% in LC. There were no complications of MLC, conversions from MLC to LC, or open surgery.
 Conclusions: The frequency of achieving CVS in MLC was higher than in LHE (97.8 % vs. 93.0 %). Anatomical variations of the biliary system should always be considered for the safe cholecystectomy. MLC is a safe technique that is not inferior to standard LCE in elective surgery in patients with a normal BMI, and at the same time has better cosmetic results.
