2 Usually benign (0.01% are sarcomas) muscle growths of the uterus Most common gyn tumor present in 30% of women in reproductive age Majority are asymptomatic However, 75% of hysterectomies are performed for menorrhagia with fibroids Can occur on a stalk on the outside of the uterus. In the uterine wall, or on the inside of the uterus Exam Ultrasound MRI CT Laparoscopy Pressure to pain Menorrhagia Dyspareunia Infertility 2

3 Endometrial ablation Myomectomy open, laparoscopic, da Vinci, or hysteroscopic Uterine artery occlusion da Vinci or embolization Myolysis Medical GnRH agonist (Lupron) Hysterectomy open, vaginal, straight stick laparoscopic or da Vinci Presence of endometrial tissue outside the lining of the uterine cavity or Proliferation of endometrium in any site other than the uterine mucosa Age: common in reproductive period True Incidence Unknown:? 1-5% & % infertility. Does NOT Discriminate by Race. Histology: Endometrial Glands with Stroma +/- Inflammatory Reaction. Hereditary ( among sisters). 3

5 Abnormal cells Cervix (dysplasia) Endometrial lining (hyperplasia) Symptoms Cervix (dysplasia) is asymptomatic Diagnosed by PAP smear Endometrial lining (hyperplasia) often cause abnormal bleeding Diagnosed by office biopsy or D&C 5

6 Treatment options Cervix dysplasia often treated by removing part of the cervix Endometrial hyperplasia treated by hysterectomy Hormonal treatment is an experimental, short-term option Malignant growth or tumor Uterus or endometrium Cervix Ovary Ovarian Cancer Endometrial Cancer Cervical Cancer The most common gynecologic cancer Usually detected in an early stage Commonly causes post-menopausal bleeding Almost always treated with surgery 6

7 Can be detected by an abnormal PAP smear Symptoms include abnormal bleeding, discharge, or bleeding after intercourse Early stages usually treated with surgery Advanced stages treated with radiation/ chemotherapy Sometimes known as the silent killer Early cases are often curable Most women are diagnosed with advanced disease There is no screening test for ovarian cancer Hysterectomy* Supracervical hysterectomy Total hysterectomy Radical hysterectomy *Removal of ovaries & fallopian tubes depends upon pathology Lymph node removal for cancer staging Myomectomy Vaginal suspension 7

8 Most common female surgery Definitive solution for many uterine conditions 650,000 procedures annually Most performed through abdominal (open) incision Advances in minimally invasive surgery (MIS) for hysterectomy More GYN surgeons performing MIS for hysterectomy Open (abdominal) surgery Minimally invasive surgery (MIS) Vaginal surgery Conventional laparoscopic surgery da Vinci Hysterectomy (robot-assisted surgery) Reduced blood loss Fewer complications Shorter LOS Faster recovery Less scarring Circa

9 Pros Minimally invasive Less pain compared to abdominal hysterectomy Short length of stay (LOS) Cons Difficult to perform Reduced visualization Not indicated for many patients Nulliparious Multiple fibroids (or large masses) Cancer Adhesions, e.g., endometriosis, prior pelvic surgery Obesity Laparoscopic Surgery Minimally invasive surgery (MIS) Ability to operate through small keyhole incisions Camera and instruments fit through the keyhole incisions Better visualization than open surgery Evolution of Surgical Access Minimally invasive Ability to operate through small, keyhole incisions Better visualization than open surgery Open Vertical Incision Open Transverse Incision Laparoscopic Incision or da Vinci Surgical Incision 9

10 Surgeon operates from a 2D image Straight, rigid instruments (limited range of motion) Instrument tips controlled at a distance Reduced dexterity, precision & control Unsteady camera controlled by assistant Dependent on assistant for surgical support through accessory port Greater surgeon fatigue Makes complex operations more difficult How do we overcome these drawbacks? Better visualization Better instrument control Better dexterity for technically challenging aspects of the procedure Better ergonomics State-of-the-art robotic technology Surgeon in control Assistant has direct access 10

11 Surgeon immersed in 3D image of the surgical field Surgeon directs precise movements of the instruments using Console controls Conventional laparoscopic instruments are rigid with no wrists EndoWrist Instrument tips move like a human wrist Allows surgeon to operate with increased dexterity & precision 11

12 Small Wristed Instruments Through Keyhole Incisions da Vinci System patented EndoWrist instruments are small and fit through keyhole incisions EndoWrist Instruments fit through dime-sized incisions A wide range of instruments are available Double-click to view video Surgeon has Improved visualization Better instrumentation, surgical control & precision Better surgical dexterity for complex aspects of procedure Easier & faster suturing Better ergonomics 12

13 General laparoscopic surgery (2000) Radical prostatectomy (2001) Thoracoscopically assisted cardiotomy procedures (2002) Intracardiac procedures (2002) Coronary revascularization (2004) Urologic surgery (2005) Gynecologic laparoscopic surgery (2005) Total abdominal hysterectomy (TAH) Laparoscopically-assisted vaginal hysterectomy (LAVH) Total laparoscopic hysterectomy (TLH) Total supracervical hysterectomy (TSH) Now there is davinci Hysterectomy da Vinci Surgery appropriate for a broader range of gynecologic conditions & patient situations compared to conventional laparoscopy Cervical cancer Conventional laparoscopy not widely accepted Endometrial cancer Conventional laparoscopy accepted, but technically difficult to perform Vaginal or uterine prolapse Conventional laparoscopic suturing not reliable Endometriosis Uterine fibroids Obese patients 13

14 Goals of da Vinci Hysterectomy Enable more precise, meticulous dissection Around ureters & bladder Colpotomy Increase ability to visualize & dissect compromised anatomy & tissue planes Endometriosis, prior pelvic surgery (e.g., C-sections) Suture more easily & quickly Better vaginal cuff closure Provide benefits of minimally invasive surgery to vast majority of hysterectomy candidates 1 day LOS, minimal pain, quick recovery, cosmesis Enables GYNs to treat complex pathology endoscopically Unsurpassed precision, dexterity & control offer potential for: More precise & efficient dissections Ureters, vesico-uterine reflection, colpotomy Quicker, easier vaginal cuff closure Greater ability to perform MIS on more patient types Compromised anatomy & tissue planes, e.g., due to endometriosis & adhesive disease from prior pelvic surgeries Larger pathology Obese patients Enables GYNs to offer the potential benefits of MIS to more of their hysterectomy patients Short hospital stay Minimal blood loss Fewer complications Less risk of infection Significantly less pain Faster recovery Improved cosmesis Equivalent or better outcomes 14

15 40,000 procedures performed annually Most performed through abdominal (open) incision Size, number & location of fibroids may require complete removal of uterus Advances in minimally invasive surgery (MIS) for myomectomy More GYN surgeons performing MIS for myomectomy Goals of da Vinci Myomectomy Enable minimally invasive surgery (MIS) approach Conventional laparoscopy for myomectomy is very difficult to learn & perform Most myomectomies performed through open incision Enable women to retain their uterus* Provide means for women to preserve their fertility Provide benefits of MIS to myomectomy patients Short hospital stay Minimal pain & scarring Quick recovery & return to normal activities *Assumes women is a surgical candidate for myomectomy. da Vinci Myomectomy Enables MIS approach for myomectomy Open is standard; laparoscopy very difficult to learn/perform Effective 3-layer suture reconstruction difficult Concern over conversions & uterine rupture Most GYNs perform open or opt for hysterectomy instead Advantages over laparoscopy Better suture reconstruction & faster than laparoscopy Advantages over laparotomy Potential patient benefits associated with MIS Longer procedure times outweighed by improved outcomes Short LOS, min EBL, min comps or conversions, quick recovery, better cosmesis 15
