   description

   Laparoscopic radical hysterectomy with pelvic lymphadenectomy are performed with Thunderbeat technology: using Thunderbeat technique, surgeons can avoid changing instruments during surgery since Thunderbeat combines bipolar energy for haemostasis and ultrasound for dissection and cut. Thunderbeat is used to divide the round ligaments, to seal ovarian pedicles, to open the anterior and posteriors leaves of the broad ligaments peritoneum, to incise the bladder peritoneum, to develop the paravesical and pararectal spaces, to seal uterine arteries and uterine pedicles, to dissect the bladder and develop rectovaginal septum, to unroof the ureter, to cut parametria, and to divide the uterosacral ligaments. Monopolar hook is used in the culdotomy. Thunderbeat is also used to perform pelvic lymphadenectomy.

   Laparoscopic radical hysterectomy with pelvic lymphadenectomy are performed with standard bipolar electrosurgery. A 10 mm port is inserted at the umbilicus for the telescope. Once pneumoperitoneum (12 mmHg) is achieved, intra-abdominal visualization will be obtained with a 0° high-definition telescope. Two additional 5 mm ports are placed under direct visualization. One more 5-mm trocar is inserted in the right mid abdomen at the level of the umbilicus. The instruments used include bipolar grasper, monopolar scissors, monopolar hook, various graspers and a suction irrigation system.
