[Use of ultrasonic surgery in laparoscopic cholecystectomy].

Introduction: Laparoscopic cholecystectomy now represents a valid alternative to traditional surgery in the treatment of gallstone diseases. For the past twenty years laparotomic cholecystectomy has represented the golden standard of gallstone treatment given its extremely low mortality rate (0.5%) and equally acceptable morbidity rate. Laparoscopic cholecystectomy now appears to have taken over the position of elective treatment. Sophisticated techniques, such as ultrasound scalpels make this form of surgery particularly safe.
Materials and Methods: The authors report a series of 50 patients who underwent laparoscopic cholecystectomy in which ultrasound surgery was used in 40 cases using the CUSA system. The gallbladder hilus is prepared using ultrasound manipulation following the secure identification, respect and clipping of the cystic artery and duct.
Discussion and Conclusions: Laparoscopic cholecystectomy appears to be the ideal treatment for gallstone diseases. In the series reported here the use of the ultrasound scalpel allowed the gallbladder hilus to be reach skeletization, preserving the main structures and keeping the operating field clean and blood-free, without increasing operating times. The possibility of severe accidents, such as vascular lesions to the hepatic artery or vena portae, or damage to the common bile duct or other abdominal organs are reduced using this technique.
