Minimal invasive laparoscopic hysterectomy with ultrasonic scalpel

Background: The purpose of the study was to assess whether total laparoscopic hysterectomy with the ultrasonic scalpel offers advantages in term of intraoperative and postoperative outcomes over the conventional abdominal hysterectomy. Methods: A case-control study to compare patients undergoing total laparoscopic hysterectomy and women undergoing abdominal hysterectomy for benign conditions was designed. Matching criteria were the menopausal status, the need of adnexectomy, and the uterus weight. The laparoscopic procedure was carried out using an ultrasonically activated scalpel and the amputated uterus was removed transvaginally. Every part of the operation was carried out via laparoscopy, from the adnexal phase to the colpotomy. Abdominal hysterectomy was performed using a conventional laparotomic technique. Intraoperative and postoperative characteristics were analyzed. Results: One hundred forty-four patients were enrolled, of whom 48 underwent total laparoscopic hysterectomy and 98 abdominal hysterectomy. No difference was found between groups in terms of operating time or intraoperative and postoperative infectious and noninfectious complications. The median (range) total consumption of morphine (0 mg [0 to 16] versus 15 mg [0 to 100], P <0.01) during the first 3 postoperative days was significantly lower in the laparoscopic group than in the laparotomic group. The median (range) time to regular diet (1[0 to 4] versus 2 [0 to 5], P <0.05) and the time to passage of stool (1[1 to 2] versus 2 [1 to 5], P <0.05) was shorter in the laparoscopic than in the laparotomic group. Conclusions: Total laparoscopic hysterectomy with the ultrasonic scalpel is feasible and safe, and offers not only cosmetic benefits but also reduces the need of analgesia and the time to return to a normal gastrointestinal function in comparison with the conventional abdominal hysterectomy.
