title: Comparison the efficacy of laparosonic coagulating shears and electrosurgery in laparoscopically assisted vaginal hysterectomy: preliminary results.
abstract: OBJECTIVE
  To compare the safety and effectiveness of laparosonic coagulating shears (LCS) and electrosurgery for use in laparoscopically assisted vaginal hysterectomy (LAVH).
  
  
  METHODS
  In this prospective study, patients undergoing LAVH performed by one of the authors from October 1997 to January 1998 were assigned at random to the electrosurgery group (n = 20) or the LCS group (n = 20). Procedures performed with LCS or electrosurgery included coagulation and separation of infundibulopelvic or utero-ovarian round ligaments, vesico-uterine-visceral peritoneal fold dissection, and anterior and posterior colpotomy. Outcome measures were operative time, blood loss, decrease in hemoglobin values, and length of hospitalization.
  
  
  RESULTS
  The mean operative time (90+/-22.9 min versus 80.3+/-17.1 min, P = 0.391), blood loss (308+/-167 ml versus 250+/-104 ml, P = 0.11), and hemoglobin decrease (1.57+/-0.769 mg/dl versus 1.36+/-0.886 mg/dl, P = 0.55) were slightly greater in the LCS group than in the electrosurgery group, although these differences were not statistically significant. The length of hospital stay was similar in the two groups (5 days). No patients developed serious complications related to electrosurgery or LCS.
  
  
  CONCLUSIONS
  Our findings indicate that LCS is as safe and effective as electrosurgery, and may offer an alternative option for patients undergoing LAVH.
