Text: With increasing experience in laparoscopic surgery, a number of centers have reported on the use of laparoscopic cholecystectomy for acute cholecystitis, suggesting that it is technically feasible but at the expense of a high conversion rate, which can be up to 35 per cent and common bile duct lesions. The HARMONIC SCALPEL (H) is the leading ultrasonic cutting and coagulating surgical device, offering surgeons important benefits including : minimal lateral thermal tissue damage, minimal charring and desiccation. Harmonic Scalpel technology reduces the need for ligatures with simultaneous cutting and coagulation : moreover there is not electricity to or through the patient Harmonic Scalpel has a greater precision near vital structures and it produces minimal smoke with improved visibility in the surgical field. In retrospective series LC performed with H was demonstrated feasible and effective with minimal operating time and blood loss : it was reported also a low conversion rate (3. 9 %).
