Background and purpose: The introduction of laparoscopic cholecystectomy in 1989 marked the beginning of the laparoscopic revolution. Despite of the rapid learning curve, the complication rates of bile duct injuries after laparoscopic cholecystectomy count from 0.4% to 0.5% compared to 0.2% after open cholecystectomy. Strasberg et al., introduced an important method to reduce BDIs in1995, who described how a critical view of safety (CVS). Materials and Methods: This study was carried on 30 patients with chronic calcular cholecystitis in the department of General Surgery, Zagazig University Hospitals during the period from September 2015 to September 2016. The patients divided into two groups : Group (A): was managed by critical view of safety technique .Group (B): was managed by conventional infundibular technique. Results: The age of the studied patients in group (A) ranging from 25-56 years old with mean 37.8±9.9 and most of the studied patients are females(73.3%) and in group (B) ranging from 23-51 years old with mean 39.5±8.2 and most of the studied patients are females(73.3%). infundibular technique has significantly longer Operative time. no significant association between bleeding and groups. no significant association as all cases with no intraoperative bile injury. there is significant association as regard drain insertion between CVS and infundibular groups . no significant difference in hospital stay as all cases discharged on the 1st postopratve day. Conclusions: The critical view of safety has an important role in decreasing the operative time because of the safe accurate identification of the anatomy that allow the surgeon to proceed without fear of misidentification
