Why FDA hearing on morcellation safety could drive innovation
Reaction from Cheryl Iglesia, MD, Advisory Panel Member, to FDA’s 2-Day Hearing
Solution #3: Illuminate the cavity
The deep pelvic cavity can be easily illuminated using a lighted suction tip, a flexible light source (as part of the cystoscopy set) held with a Babcock clamp (FIGURE 3), or a malleable illuminating mat taped to the retractor blades (such as Lightmat surgical illuminator, Lumitex, Inc., Strongsville, Ohio).
Solution #4: Project the image
Cameras attached to an overhead boom or operating room light handles (FIGURE 4) and an external telescope with integrated illumination, such as a standard cystoscope or VITOM Exoscope (Karl Storz, El Segundo, California) (FIGURE 5) provide both magnification and projection of the procedure to an overhead monitor.
Glass technology (Google, Mountain View, California) also has been utilized in surgery and can be a good application of simultaneous projection and recording of the procedure to an external monitor (FIGURE 6). Google Glass is a wearable computer with an optical head-mounted display. The device, similar to eyeglasses, is voice-activated, thereby allowing the surgeon to record the procedure hands-free. Simultaneous projection to an external monitor allows the entire team in the operating room to be aware of the flow of the procedure.
Challenge: Working in a narrow vaginal vault
Without correct instrumentation, this challenge can be especially daunting. Laparoscopy and robotics have changed the way we perform pelvic surgery by providing advanced instrumentation.
Solution #5: Adapt your instruments
Modified vaginal instruments can be used to facilitate a case. Watch the accompanying VIDEO on the use of improved vaginal instruments during morcellation.

Among the instruments adaptable for vaginal surgery:
- curving, articulating instruments
- long, curved, and rounded knife handles, which allow for better ergonomics during prolonged morcellation
- modified long retractors and use of a single long vaginal pack provide retraction of loops of bowel and easy access to secure pedicles deep in the pelvis.
All of these instruments are available through Marina Medical in Sunrise, Florida.
Challenge: Securing vascular and thick tissue pediclesA narrow introitus and vaginal vault can be difficult to manage during vaginal surgery. Another challenge is a uterus that is large or deformed by multiple fibroids.
Solution #6: Vaginal incision
A simple superficial 2- to 3-cm incision on the distal posterior aspect of the vaginal wall can widen the introitus and vault to facilitate the procedure (FIGURE 7)
Solution #7: Vessel-sealing tools
The use of energy is integral to laparoscopy and robotics for dissection and securing vessels. In a meta-analysis that included seven randomized controlled trials, advanced vessel-sealing devices proved useful in vaginal surgery by decreasing blood loss and operative time.8
In the setting of a difficult vaginal hysterectomy with a narrow introitus and large uterus, the use of vessel-sealing technology allows the surgeon to skeletonize the uterine arteries while allowing progressive descensus to secure the upper pedicles.
In my experience, the use of an advanced vessel-sealing device, compared with traditional clamp-cut-tying technique, facilitated successful completion of vaginal hysterectomy in 650 patients with relative contraindications to the vaginal approach, such as nulliparity, a uterus weighing more than 250 g, and a history of cesarean delivery (Mayo Clinic data; yet unpublished).
We must change with the times
The rate of vaginal hysterectomy will continue to decline unless we modify our technique to incorporate new technology. The current generation of practicing gynecologists and recent graduates are choosing the laparoscopic and robotic approaches because of the advantages these technologies offer. It is time we incorporate relevant features from these minimally invasive approaches while maintaining patient safety and containing costs by performing vaginal hysterectomy whenever possible. A willingness to change and ability to think outside the usual box will help us train new generations of vaginal surgeons who can bring back vaginal hysterectomy as the preferred route to the benign hysterectomy.
