Comparison of Use of Ultrasonic Surgical and Bipolar Coagulator System on Laparoscopic Assited Vaginal Hysterectomy.

Objective: 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 test and student t-test as appropriate. Statistical significance was defined as p3 vs 484 years. The mean operating time was 5413 min vs 376 min. The mean weight of uterus was 320135 g vs 315121 g. The mean hemoglobin drop was 2.420.85 g/dL vs 1.970.74 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.
