Abstract:
This was a review of 512 consecutive cases of laparoscopic-assisted vaginal hysterectomy (LAVH) for benign gynecologic conditions with the Biswas uterovaginal elevator (BUVE) from February 2003 through June 2008. A single operator, using the BUVE and a standard surgical protocol, performed all hysterectomies. Variables analysis included patient demographics, operative times, uterine weight, hospital stay, intraoperative blood loss, and intraoperative and postoperative complications. LAVH was successfully performed for all patients. The median operative time was 62 [corrected] minutes, range 35 to 250 minutes. The median uterine weight was 231 [corrected] g (range 43-1690 g). The median estimated blood loss was 100 [corrected] mL (range 5-1600 mL). The median length of hospital stay was 1 [corrected] days (range 1-6 days). [corrected] No case sustained injury to the ureter or major vessels or required conversion. LAVH with the BUVE eliminates the need for laparotomy in performing hysterectomies for benign gynecologic disorders. The BUVE can achieve a full range of uterine manipulation. It allows safe and easy dissection of the bladder and precise colpotomy through simultaneous uterine elevation and delineation of vaginal fornices. Prevention of ureteric injury is made possible by moving the surgical field away from the ureter. The technique described can be used to handle a wide variety of diseases and situations and has been shown to be safe, fast, easy to learn, and reproducible and carries few complications.
