This Video demonstrate a dangerous way of Performing Laparoscopic Cholecystectomy by Harmonic Scalpel In Mass Shearing. Ideally a nice dissection of calot's triangle with critical view of safety should be done. World wide laparoscopic cholecystectomy (LC) has become the customary method for treating gallstones, some incidents and complications appear rather more frequently than with the open technique. Several aspects of these complications and their treatment possibilities are analysed and clipless cholecystectomy with Harmonic scalpel is one of them. During the past decade world wide laparoscopic cholecystectomy has become the procedure of choice in the surgical treatment of symptomatic gallstone. The operation is not completely risk-free, some incidents and complications being more frequent than with open cholecystectomy. The use of the Harmonic scalpel is deemed safe and comparable to clip placement at the discretion of the surgeon for cystic duct ligation. According to the article published by many author, harmonic shears is effective and safe in laparoscopic cholecystectomy as a sole instrument for sealing and division of the artery and cystic duct. The main advantages could be related to the safety and decreased operative time. Further research with larger homogeneous studies and assessments of cost-effectiveness would further enhance the increasing use of the Harmonic scalpel in laparoscopic cholecystectomy.
