Frank W. Jansen, Chair
Faculty: Amy N. Broach, Sarah L. Cohen, Kimberly A. Kho,
Cara R. King, Suketu Mansuria, Lukas van den Haak This course is designed to provide participants with a systematic and comprehensive overview of laparoscopic hysterectomy from leading experts in the field. The course will focus on practical skills that will help surgeons become more efficient and safe, as well as advanced surgical strategies to tackle more difficult cases (i.e., large fibroid uteri, adhesions, etc.) without conversion. The course will emphasize education using surgical videos to enhance the applicability of the techniques taught and demonstrate practical utilization of these methods. Participants will bridge the gap that separates novice from expert surgeons through a thoughtful overview of proper surgical technique, retroperitoneal anatomy, complication avoidance and management, laparoscopic suturing, and laparoscopic instrumentation. The afternoon cadaveric lab will include the opportunity to immediately apply skills presented in the didactic course to the “real world.” In order to support AAGL’s tissue extraction statement, this course will discuss the following tissue extraction methods: Contained vaginal morcellation, contained minilaparotomy morcellation and contained power morcellation. Learning Objectives: At the conclusion of this course, the clinician will be able to: 1) Describe and perform fundamental laparoscopic skills, including but not limited to, identification and dissection of the retroperitoneal space, laparoscopic ureterolysis, laparoscopic suturing, and refining surgical strategies for success when faced with intra‐operative challenges; 2) demonstrate the proficiency to identify retroperitoneal anatomy, especially the uterine artery from its origin, in order to complete difficult cases and minimize conversion to laparotomy; and 3) employ time‐tested tips and tricks to improve surgical efficiency and patient outcomes.

Quality and LH?
Measuring quality for LH is difficult
Objective quality measurement tools are not available
Case‐mix
Relevancy, Evidence, Feasibility & Steerable
www.QUSUM.org
Types of Quality Indicatorsaccording to Donabedian
15‐okt‐15
• Structure: reflect the setting• Case volume• Access to specific technologies • Staff certification
• Process: include complete care system• Multidisciplinary team management• Protocols/guidelines
• Outcome: refer to direct clinical outcomes• Complications• Morbidity• Mortality• Quality of life (PROMS)
Most used to assess the quality of surgical care
Problem of Quality IndicatorsLack of case‐mix correction
15‐okt‐1515
Patients are heterogeneous
Incorrect comparison of outcomes between hospitals and surgeons!
Quality indicators for LH
Conversion associated with worse outcomes
• Prolonged length of surgery
• More postoperative adverse events
• Prolonged hospital admission

Consensus on definition of conversionBlikkendaal et al Surg Endosc 2014
Conversion to laparotomy is an intra‐operative switch from a laparoscopic to an open abdominal approach that meets the criteria of one of the two subtypes:
– Strategic conversion: a standard laparotomy that is made directly after the
assessment of the feasibility of completing the procedure laparoscopically* and because of anticipated operative difficulty or logistic considerations
– Reactive conversion: the need for a laparotomy because of a complication or
(extension of an incision) because of (anticipated) operative difficulty after a considerable amount of dissection (i.e. in time >15 minutes)
•A laparotomy after a diagnostic laparoscopy (i.e. to assess the curability of the disease) should not be considered as a conversion
•<5% Strategic (indication) <1% reactive (complication risk)

Cystosufflation technique6
• Urinary catheter must remain within the sterile field
• Remove urethral catheter from drainage bag
• Under direct visualization, “back fill” the bladder with carbon dioxide gas
• Use as much gas as necessary to define the borders of the bladder
• May “hold” the air in the bladder with a Kelly clamp to work with an inflated bladder or release and refill as many times as necessary
All Rights Reserved, Duke Medicine 2007
Diagnostic tool for bladder and ureteral injury
• 25% of all visceral injuries are diagnosed post-operatively 7
• Bladder and ureteral injuries are the most common visceral complications of laparoscopic hysterectomy 8
• Simple technique to evaluate the bladder and ureters: “Poor Man’s Cystoscopy” 9
– Took 13 minutes longer
– Diagnosed bladder and ureteral injuries
– Will not diagnose fistulas
All Rights Reserved, Duke Medicine 2007
Poor Man’s Cystoscopy

All Rights Reserved, Duke Medicine 2007
Poor Man’s Cystoscopy 9
• Back fill the bladder with ~200 mL of normal saline or sterile water*
– Using suction-irrigator tip
– Through the urethral catheter*
• Insert 30 degree laparoscope into the bladder to evaluate mucosa, efflux of ureteral urine
– 2.5 mL of indigo carmine may be required when using normal saline

Practical Review of Retroperitoneal Anatomy
Suketu Mansuria, M.D.
Associate Professor
Assistant Director Gyn MIS
UPMC
Disclosures
I have no financial relationships to disclose
Objectives
• Review pelvic sidewall (retroperitoneal) anatomy
• Review techniques to develop avascular spaces of the pelvis and identify uterine artery from its origin
• Review importance of retroperitoneal anatomy– In the management of commonly seen pathology during laparoscopic hysterectomies
– In minimizing conversion to laparotomy and minimizing complications
Pelvic Sidewall
• Why is retroperitoneal anatomy important?
– Important structures in the retroperitoneum:
• Uterine artery‐control of the uterine blood supply is 75% of a hysterectomy
• Ureter‐knowledge of its retroperitoneal course will minimize ureteral injury
– Very rarely does pelvic pathology affect the retroperitoneal anatomy
• Adhesions
• Endometriosis
Pelvic Sidewall
• Uncertainty regarding retroperitoneal structures often leads to conversion to laparotomy
– Bleeding
– Concern for ureter
• THE ANATOMY ISN’T EASIER OPEN!!!
• Intra‐pelvic pathology can often be managed through a retroperitoneal approach!!!
• FOR EXAMPLE:
Pelvic Sidewall• Fibroid uterus
– Limited access to the traditional coagulation point
• Usually due to very wide uterus or lower uterine segment/cervical fibroids
• Control uterine artery at its origin
– Better exposure
– Decreased risk of ureteral injury
– Control blood supply prior to myomectomy
• Prior to traditional myomectomy
• Prior to removing fibroids to improve exposure during a laparoscopic hysterectomy
17
Pelvic Sidewall• Obliterated cul de sac/Scarred bladder flap
– Leave the adhesions for the last step of the case
• “Do the easy stuff first, and the hard stuff becomes easy!”
– Devascularize the uterus before attempting adehesiolysis
• Control the uterine blood supply without injuring the bowel or bladder
• Devascularizing the uterus prior to adhesiolysis will minimize bleeding/improve visualization‐decreasing the risk of bowel/bladder injury
Pelvic Sidewall• Bleeding
– Control bleeding uterine pedicle
• Decreased risk of ureteral injury
• Endometriosis‐can alter course of ureter
• Adnexa adherent to sidewall
– Allows complete removal of sidewall
– Minimize risk of ovarian remnant syndrome
• Allows for complete ureterolysis
– Ureter travels beneath the uterine artery/allows for dissection thru the parametria
Pelvic Sidewall
• Two important structures in the pelvic sidewall/retroperitoneum
– Ureter‐ALWAYS found along the posterior leaf of the broad ligament
– Uterine Artery‐ALWAYS crosses above the ureter(water under the bridge)
Pelvic Sidewall
• Two Important Avascular Spaces
– Pararectal space
– Paravesical space
• Both spaces are triangles and share a common base – the uterine artery
• As long as you can identify one boundary of either space, you can develop both spaces and identify all the other boundaries

Pelvic Sidewall
• Three main surgical approaches to identifying the uterine artery from its origin off the hypogastric artery
– Posterior approach
– Lateral approach
– Anterior approach
• Choice of approach will be determined by visualization and anatomy
Pelvic Sidewall
• Posterior Approach– Make a peritoneal incision between the IP ligament and the ureter (If there is difficulty identifying the ureter, start at the pelvic brim)
– Extend the peritoneal incision from the pelvic brim towards the uterus‐have your assistant pull the peritoneum medially
– Develop the pararectal space
– Identify all borders of the pararectal space and use them to identify the paravesicle space
Pelvic Sidewall
• Lateral Approach‐the approach most familiar to most gynecologist
– Make a peritoneal incision from the round ligament parallel to the IP ligament
– Have your assistant pull the peritoneal edge medially
– Develop the pararectal space
– Identify all borders of the pararectal space and use them to identify the paravesicle space
19
Pelvic Sidewall
• Anterior Approach‐Used when the other two approaches are not possible (ie. obliterated cul‐de‐sac, very large and broad uterus)– The medial umbilical ligament is identified– The MUL is skeletonized and followed retrograde towards the uterine artery
• Concentrate dissection on the medial side of the ligament (the paravesicle space will be developed)
• Superior vesicle artery will be encountered before the uterine artery – SVA originates from the posterolateral aspect of the hypogastric artery and runs upwards to the bladder
– Once the uterine artery identified, use it to identify all other structures

Laparoscopic Instrumentation:The Pros and Cons of Various Energy Devices
Kimberly Kho, MD, MPH
University of Texas Southwestern Medical Center
Dallas, TX
Disclosures
• Contracted/Research: Applied Medical
• Other: Pivotal Protocol Advisor: Actamax
Learning Objectives
• Review available laparoscopic energy devices
• Examine mechanism of action and indications for use of various devices
• Compare pros and cons of devices
• Discuss various surgeon preferences, specific circumstances and reasons for use
History
• 1989 1st LAVH by Reich using suture for vessel ligation
• With lasers, traditional bipolar and monopolar initial concerns about:
– Thermal spread/damage
– Consistency of hemostasis
Principles of Electrosurgery
• Ohm’s law: V = I x R• Electrosurgery vs electrocautery• Monopolar vs. Bipolar Electrosurgery• Ultrasonic Energy• Laser
– Light Amplification by Stimulated Emission of Radiation
• Tissue effect = time, power density (power settings, spot size)
• + : accuracy, lack of thermal spread• ‐ : cost, availability, maintenance, training
Monopolar Electrosurgery
Law KS, Abbott JA, Lyons SD. Obstet Gynecol Surv. 2014. 69(12): 764‐776.
21
Bipolar Electrosurgery
• Developed to decrease risk of stray current
• Advantages:
– “Closed circuit”
– Lower voltage for tissue effect
– Thermal effect more evenly distributed
• Disadvantages:
– Larger electrodes (2)
– Tissue sticking
Advanced Bipolar Devices
• “Advanced” because of feedback‐controlled dessication
• Utilize pulsatile, impedence‐controlled – Lowest possible power for tissue effects
• Denatures collagen and elastin in vessel walll ‐> forms coagulum
• Ligasure adjusts I and V based on real‐time impedence
• Gyrus employs pulse/cool‐off period to reduce drying/sticking
• Enseal RX uses proprietary electrode w/ temperature sensitive conductive particles
Levy BS. OBG Mgt, Sept 2009.
Vessel Sealing Devices
• How are they assessed? – Seal time
• Shortest w/ Ligasure w/ Force Triad generator
– Burst pressure • 6‐7mm vessels, no significant difference
– % failure rate (consistency)• Highest Gyrus
• Lowest Ligasure, Enseal
– Thermal spread • Coagulation necrosis noted :
– <3mm for LS, HS, PK
– 6mm for Gyrus Plasma
– Other authors up to 22 mm for non‐impedence bipolar
Newcomb WL, Hope, WW, Schmelzer TM et al. Comparison of blood vessel sealing among new electrosurgical and ultrasonic devices. Surg Endsoc 2009.
Ultrasonic Devices
• Harmonic Scalpel – pizoelectric ceramic tip
– converts electrical impulses to mechanical energy, vibrates @ 55K cycles/second
– Set power (e.g. excursion distances) for modification of cutting and coagulation
– Seals created by breaking hydrogen bonds btw tissue proteins ‐> coagulum
• Creates water vapor
Comparison of Devices Comparative Costs of Vessel Sealing Devices
Reusables Disposables
5‐mmLigaSure $17,000 Base station/generator $230
Harmonic scalpel $15,750 Base station/generator $341

Advanced Techniques for Tackling the Large Uterus or
Complex Pelvis
Suketu Mansuria, M.D.
Associate Professor
University of Pittsburgh Medical Center
Disclosures
• I have no financial relationships to disclose
Objectives
• Discuss surgical strategies utilizing the retroperitoneum to accomplish difficult hysterectomies
• Discuss techniques to minimize conversion to laparotomy and minimize complications
• Review pelvic sidewall anatomy
– Identify the uterine artery from its origin to facilitate difficult cases
The Retroperitoneum
• Why is knowledge of the retroperitoneumimportant?
– Uterine artery
– Ureter
• Allows you to accomplish difficult cases
– Fibroid uteri
– Scarred bladder flaps
– Obliterated cul‐de‐sacs/endometriosis
– When a ureterolysis is necessary
Uterine Manipulators
• Most important assistant is the uterine manipulator
– I prefer the Pelosi manipulator
• Heavy duty
• Great anteversion/retroversion and lateral deflection
• Different size tips
Pelosi Manipulator
24
Difficult Hysterectomies
• Ureteral Stents
– Helps with identification of the course of the ureter along the pelvic sidewall
– Helpful when visualization of the ureters may be compromised due to low fibroids and endometriosis (and obesity!)
– Placement of stents does NOT absolve the surgeon from needing to know where the uretersare‐it just makes finding them easier
– Can aide in ureterolysis
• Ureters more rigid and more easily bluntly dissected out of harm’s way
Port Placement• Port Placement
– Rarely does the port placement need to be modified for large uteri less than 24 weeks size (larger than that may require the optical port to be placed more cephalad)
• Keep in mind that 90% of the case is securing the blood supply
– Upper pedicles‐even in large uteri the upper pedicles are rarely much above the level of the pelvic brim
– Lower pedicles‐often the more difficult pedicles to secure and even in larger uteri the lower pedicles are still deep in the pelvis. Therefore if the ports are positioned too cephalad, this may compromise access to the deep pelvis (where the majority of the case will be performed)
Port Placement
5 mm
10 mm
Difficult Hysterectomies
• Surgical approach– 90% of the case is securing the blood supply
• 4 Vessels need to be secures– 2 upper pedicles (utero‐ovarians or IP’s)
– 2 lower pedicales (uterine)
• If the four vessels cannot be secured within 1.5‐2 hrs convert to laparotomy
– Secure the blood supply first and then perform:• Removal of the fibroids prior to hysterectomy
• Adhesiolysis for scarred bladders or bowel adhesions in the posterior cul‐de‐sac
• Ureterolysis
– “Do the easy part first and then the hard parts become easy!”
Fibroid Uteri
• Securing the blood supply– Upper pedicles are usually very easy
• In patients where the ovaries are to be removed, it is often easier to initially leave them in place (ie. secure the utero‐ovarian ligament) and then remove the ovaries after the hysterectomy has been completed
– Often easier to access the utero‐ovarian ligament compared to the IP ligament when a large uterus is in situ
– Don’t have to worry about the location of the ureters when your visualization is compromised
– Taking down the upper pedicles will often improve the mobility of the uterus (esp. the round ligaments)
Fibroid Uteri
• Securing the lower pedicles (ie. uterine arteries)
– Often if the fibroids are all in the upper part of the uterus, the anatomy/course of the uterine artery is not different from normal size uteri and can be controlled in the traditional fashion
• Make sure the uterus is pushed “up” (cephalad) as much as possible
• Stents can help give you reassurance that the uretersare well out of the way
25
Difficult Hysterectomies
• Securing the lower pedicles (ie. uterine arteries)
– Securing the uterine artery at its origin off the hypogastric (internal iliac) can be helpful when dealing with fibroids:
• Easier to control large vessels (ie. decreased bleeding)
– Able to “get around” the whole vessel
• Often sidewall exposure is better than at the traditional coagulation point
• Sidewall anatomy often less distorted
• Able to control uterine blood supply before performing myomectomies to aide in hysterectomy
Difficult Hysterectomies
• Securing the lower pedicles (ie. uterine arteries)
– Securing the uterine artery at its origin off the hypogastric (internal iliac) can be helpful when dealing with a scarred bladder flap or obliterated cul‐de‐sac:
• Sidewall anatomy often less distorted
• Able to control the uterine blood supply when bowel or bladder is in close proximity to the traditional coagulation point
• Once the uterus is devascularized, able to perform adhesiolysis with less bleeding (thereby improving visualization and decreasing the risk of bowel/bladder injury)
Ureterolysis
• Knowledge of retroperitoneal anatomy can help:
– Aide in the identification of the ureter
– Aide in ureterolysis
• Since the uterine artery crosses over the ureter, controlling the artery laterally allows the surgeon to completely dissect the ureter without encountering bleeding from inadvertant injury to the uterine artery

Pelvic Sidewall
• Three main surgical approaches to identifying the uterine artery from its origin off the hypogastric artery
– Posterior approach
– Lateral approach
– Anterior approach
• Choice of approach will be determined by visualization and anatomy
Bladder Flap
• Rooney, et al (2005) case‐control study examining relationship between history of prior cesarean and GU injury during subsequent hysterectomy
– Cesarean is significant risk factor for incidental cystotomy (OR 2.04)
– Greater risk of cystotomy in laparoscopic vs. abdominal approach (OR 7.5 vs 1.26) in patients with prior cesarean
Rooney, et al Am J Obstet Gynecol, 2005
National Trends in Cesareans
• 53% increase in rate of cesarean section from 1996 until 2006
• Decrease in VBAC from 28.3% in 1996 to 8.5% in 2006
• Increase in maternal request for cesarean
Barber, et al Obstet Gynecol, 2011Gregory, et al Semin Perinatol, 2010
Bladder Flap
• When a difficult bladder flap is encountered, the approach can be broken down into discrete steps:
• Secure the blood supply
• Delineate borders of the bladder
• Initiate dissection laterally and inferiorly
Bladder Flap
• Secure the blood supply
– Secure the 4 main blood supplies to the uterus prior to initiating dissection
• This will minimize blood loss during the dissection
• Leave the bladder flap dissection for the last step prior to colpotomy
• If the bladder is severely scarred, it may be in close proximity to the location where the uterine artery is traditionally controlled. In these cases, control the uterine artery at its origin prior to making the bladder flap
27
Bladder Flap
• Delineate the borders of the bladder
• Two main techniques
– Pass a uterine sound gently through the urethra and into the bladder
• Use it to “probe” the bladder to see its borders
– Retrograde fill the bladder with 300‐400cc
• I use my suction‐irrigator and connect it to the end of the foley and clamp the foley when the bladder is full
– Once the borders are delineated, dissection can continue safely
Bladder Flap
• Initiate the dissection laterally and inferiorly
• Why?
– The bladder is usually pulled up in the midline by scarring from previous cesarean sections
– When dealing with scar tissue, it is important to find the proper plane for dissection=endopelvicfascia
– By initiating the dissection inferiorly and laterally, the endopelvic fascia can more easily be identified

Alternatives to laparoscopic power morcellation
Sarah L. Cohen MD MPH
Division of Minimally Invasive Gynecologic SurgeryBrigham and Women’s Hospital
I have no financial relationships to disclose
1. Analyze rationale behind contained tissue extraction
2. Review tips and tricks for:– Contained vaginal morcellation– Contained minilaparotomy morcellation– Contained power morcellation
3. Discuss future directions
Defining the problem• FDA statement 11/2014
– “Laparoscopic power morcellators are contraindicated for removal of uterine tissue containing suspected fibroids in patients who are peri- or post-menopausal, or are candidates for en bloc tissue removal”
• Industry response– Johnson and Johnson: Gynecare (Morcellex TM) 80%
market share of morcellation products, as of July 2014-recalls the Morcellex
• Insurance limitations– Aetna, United Healthcare require Peer to Peer review
Possible SolutionsCan we identify patients who are high risk for occult malignancy?
Should we avoid morcellation altogether?
Can we better minimize risks of morcellation via tissue containment?
– Allow patients benefits of minimally invasive surgery– Minimize risk of tissue dissemination- both benign and malignant tissue
– Has been reported in general surgery, urology and even gyn – even for malignancy
TAH
What about vaginal morcellation?
Studies on worsened prognosis with tumor disruption NOT limited to power morcellation
–Include myomectomy, LAVH, TVH, scalpel morcellation
Limitations for myomectomy, supracervicalhysterectomy
Unclear how various forms of morcellation affect risk
38
Option 1: Contained Vaginal Morcellation
• Insert containment bag of choice – Based on specimen size, use abdominal wall incision (12-15mm) or colpotomy site
• Place specimen into bag with cervix directed to opening of bag
Option 1: Contained Vaginal Morcellation
• Exteriorize bag at introitus• May utilize self retaining retractor to facilitate
unhindered exposure• Rocking motion during manual morcellation with scalpel
Contained Vaginal Morcellation: Videos
Option 2: Contained Minilaparotomy Morcellation
• Umbilicus or suprapubic, 2.5-5cm
• Tips to extend port at umbilicus– deflate abdomen, open skin, use S retractor and bovie over finger to open fascia
• Insert containment bag of choice
Option 2: Contained Minilaparotomy Morcellation
• Single port device helpful to allow for return to LSC view
• Place specimen in bag, exteriorize bag at abdominal wall
• 11 blade scalpel, morcellate in strips allowing specimen to roll

CULTURAL AND LINGUISTIC COMPETENCY Governor Arnold Schwarzenegger signed into law AB 1195 (eff. 7/1/06) requiring local CME providers, such as
the AAGL, to assist in enhancing the cultural and linguistic competency of California’s physicians
(researchers and doctors without patient contact are exempt). This mandate follows the federal Civil Rights Act of 1964, Executive Order 13166 (2000) and the Dymally-Alatorre Bilingual Services Act (1973), all of which
recognize, as confirmed by the US Census Bureau, that substantial numbers of patients possess limited English proficiency (LEP).
California Business & Professions Code §2190.1(c)(3) requires a review and explanation of the laws
identified above so as to fulfill AAGL’s obligations pursuant to California law. Additional guidance is provided by the Institute for Medical Quality at http://www.imq.org
Title VI of the Civil Rights Act of 1964 prohibits recipients of federal financial assistance from
discriminating against or otherwise excluding individuals on the basis of race, color, or national origin in any of their activities. In 1974, the US Supreme Court recognized LEP individuals as potential victims of national
origin discrimination. In all situations, federal agencies are required to assess the number or proportion of LEP individuals in the eligible service population, the frequency with which they come into contact with the
program, the importance of the services, and the resources available to the recipient, including the mix of oral
and written language services. Additional details may be found in the Department of Justice Policy Guidance Document: Enforcement of Title VI of the Civil Rights Act of 1964 http://www.usdoj.gov/crt/cor/pubs.htm.
Executive Order 13166,”Improving Access to Services for Persons with Limited English
Proficiency”, signed by the President on August 11, 2000 http://www.usdoj.gov/crt/cor/13166.htm was the genesis of the Guidance Document mentioned above. The Executive Order requires all federal agencies,
including those which provide federal financial assistance, to examine the services they provide, identify any
need for services to LEP individuals, and develop and implement a system to provide those services so LEP persons can have meaningful access.
Dymally-Alatorre Bilingual Services Act (California Government Code §7290 et seq.) requires every
California state agency which either provides information to, or has contact with, the public to provide bilingual
interpreters as well as translated materials explaining those services whenever the local agency serves LEP members of a group whose numbers exceed 5% of the general population.
~
If you add staff to assist with LEP patients, confirm their translation skills, not just their language skills.
A 2007 Northern California study from Sutter Health confirmed that being bilingual does not guarantee competence as a medical interpreter. http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=2078538.
