Professional Education Information Target Audience Educational activities are developed to meet the needs of surgical gynecologists in practice and in training, as well as, other allied healthcare professionals in the field of gynecology. Accreditation AAGL is accredited by the Accreditation Council for Continuing Medical Education to provide continuing medical education for physicians. The AAGL designates this live activity for a maximum of 3.75 AMA PRA Category 1 Credit(s)™. Physicians should claim only the credit commensurate with the extent of their participation in the activity. DISCLOSURE OF RELEVANT FINANCIAL RELATIONSHIPS As a provider accredited by the Accreditation Council for Continuing Medical Education, AAGL must ensure balance, independence, and objectivity in all CME activities to promote improvements in health care and not proprietary interests of a commercial interest. The provider controls all decisions related to identification of CME needs, determination of educational objectives, selection and presentation of content, selection of all persons and organizations that will be in a position to control the content, selection of educational methods, and evaluation of the activity. Course chairs, planning committee members, presenters, authors, moderators, panel members, and others in a position to control the content of this activity are required to disclose relevant financial relationships with commercial interests related to the subject matter of this educational activity. Learners are able to assess the potential for commercial bias in information when complete disclosure, resolution of conflicts of interest, and acknowledgment of commercial support are provided prior to the activity. Informed learners are the final safeguards in assuring that a CME activity is independent from commercial support. We believe this mechanism contributes to the transparency and accountability of CME.

PG 103 Pelvic Anatomy: Skill Set for the Savvy Minimally Invasive Surgeon –
Generalist, Urogynecologist, Oncologist (Didactic)
Jubilee Brown, Chair Faculty: Peter M. Lotze, R. Wendel Naumann
Course Description
This course is designed for advanced minimally invasive gynecologic surgeons who want to enhance their knowledge base and apply it to minimally invasive surgical procedures. The didactic portion of this course will provide detailed instruction on intra- and retroperitoneal pelvic anatomy as it applies to successful general, urogynecologic, and oncologic surgery. Experts in each subspecialty will focus on anatomy and dissection techniques to improve the surgical skills of generalists and subspecialists alike. Practical anatomy will be highlighted with MIS videos throughout, and tips and tricks of optimal dissection will be emphasized.
Learning Objectives At the conclusion of this course, the participant will be able to: 1) Identify and interpret pelvic and retroperitoneal structures; 2) discuss and analyze pelvic support defects, minimally invasive repair techniques, and avoidance of injury during such procedures; 3) detect successful approaches for surgical dissection of pelvic sidewall and retroperitoneal anatomical structures (e.g., ureter, nerves, blood vessels) in patients with complex anatomy; and 4) distinguish retroperitoneal spaces and apply these landmarks to minimally invasive surgical dissection.

Pelvic BonesPelvic BonesPelvic BonesPelvic Bones Ilium• Uppermost / largest bone
• Divisible into body, ala• Separation indicated on top surface by curved line (arcuate line), and on external surface by margin of acetabulum
• Body - part of acetabulum (< 2/5)• Wing (ala) - large expanded portion; bounds greater pelvis laterally
4
Ischium• Lower / back part of hip bone (os coxae)
• Situated below ilium / behind pubis• Superior portion forms ~1/3 of acetabulum
Pubis• Covered by mons pubis.• Body, superior and inferior ramus• Body forms 1/5 of acetabulum
SacrumSacrumSacrumSacrum• Typically 5 vertebrae - initially unfused and fuses at ~16–18 y/o (done by 34)
• Sacral promontory - projects forward and articulates with last lumbar vertebra (sacrovertebral angle)
• Centrally - curved posteriorly (allows greater room in pelvis)
• Ala (“wings”) - project laterally
5
Ala ( wings ) project laterally and articulate with ilium at sacroiliac joints
• Upper vs. Lower Half– Lower forms greater angle – Upper half nearly straight– Lower half with greatest
amount of curvature
• In the female sacrum is shorter and wider than a male

– Paresthesia over the appropriate nerve distribution
– Pain relief after infiltrating with local anesthetic
– Symptoms often worse with Valsalva and can be relieved with hip flexion
• Requires weekly injection with analgesic/steroids, neurolysis, or resection

33Morgan K, Br J Obstet Gynaecol 102:665, 1995
Obturator Nerve Injury• Most often injured during obturator node dissection
–Often due to lack of identification or bleeding
• Mostly motor with injury resulting in hip dd t k
34
adductor weakness
• If injured repair with 8‐0 to 10‐0 nylon to achieve captation without perineurial gaps or tension
–physiotherapy should be imployed
–recovery is often possible

Neuro‐Anatomy
• Pelvic viscera are innervated via the autonomic nervous system
• Sympathetic fibers
–originate in the thoracic and lumber segments of the
43
spinal cord and reach the pelvis via the hypogastric plexus
• Parasympathetic fibers
–originate in sacral nerve roots 2, 3, and 4
43
Sympathetic Nerves to the Bladder
•Long post‐ganglionic nerves
–T 11 and T 12
–L 1 and L 2
•Pre‐sacral (hypogastric nerves)
44
–beta‐androgenic fibers causing relaxation of detrusor
–alpha androgenic fibers causing contraction of the urethra
–Stimulation prevents voiding
Para‐sympathetic Nervesto the Bladder
•Motor fibers from the Sacral Nerves
–S2, S3, and S4
–course through the pelvic nerve plexus and join the hypogastric nerves to form the vesical plexus
45
the hypogastric nerves to form the vesical plexus
–Excitement of the Para‐sympathetic nerves causes contraction of the bladder resulting in micturition
•Somatic and Sensory innervation also occurs through S2 ‐ S4

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.
