title: Laparoscopic appendectomy by ultrasonically activated scalpel in acute appendicitis: preliminary report.
abstract: OBJECTIVE
  Laparoscopic appendectomy (LA) is increasingly being used in treating acute appendicitis. New instruments such as the ultrasonically activated scalpel (UAS) have been introduced for most laparoscopic procedures. We evaluated the use of UAS in the performance of LA, as the potential of this instrument in this type of surgery remains to be defined.
  
  
  METHODS
  Three patients with acute right lower abdominal pain were managed by the laparoscopic approach. Once the diagnosis of acute appendicitis was established, laparoscopic appendectomy was performed with the UAS.
  
  
  RESULTS
  The mean operative time was 42.3 minutes (range 32-49 minutes). There were no complications related to the treatment with UAS of either the vascular pedicle or the appendicecal stump. No electrosurgical coagulation, clips, loops, or endostapler was used in any patient.
  
  
  CONCLUSIONS
  Total LA performed with UAS is feasible. Use of the UAS may make dissection and resection of the appendix easier, helping to reduce the mean operative time.
