This study was to evaluate the effectiveness and value of Ultrasonic surgical system on Laparoscopic assited vaginal hysterectomy (LAVH). METHODS: Retrospective study of 42 cases of LAVH with bipolar coagulator and 85 cases of LAVH with ultrasonic surgical system in Dept of OB/GYN, Chosun University Hospital from January 2001 to December 2002 was carried out and postoperative results were compared between 2 methods. Statistical analysis was performed using x2 test and student t-test as appropriate. Statistical significance was defined as p<0.05. RESULTS: The mean age of patients (bipolar coagulator vs ultrasonic surgical system) was 49+/-3 vs 48+/-4 years. The mean operating time was 54+/-13 min vs 37+/-6 min. The mean weight of uterus was 320+/-135 g vs 315+/-121 g. The mean hemoglobin drop was 2.42+/-0.85 g/dL vs 1.97+/-0.74 g/dL. CONCLUSION: In case of LAVH of myoma or adenomyosis using bipolar coagulator or ultrasonic surgical system. The advantages of ultrasonic surgical system were shortening of operation time, less bleeding during operation and less smoke caused by high temperature coagulation.
