Fibroids: Myomectomy and New Approaches (Didactic) PROGRAM CHAIR Tommaso Falcone, MD Ted L. Anderson, MD Jon I. Einarsson, MD Sponsored by AAGL Advancing Minimally Invasive Gynecology Worldwide 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.

Anderson, Jon I. Einarsson Course Description This course is designed for all gynecologists who wish to expand their experience in the management of myomas. The course is designed to be case-based and each presentation will include several illustrative cases. The program will emphasize practical information with multiple video demonstrations of surgical techniques. The program will begin with a fundamental review of preoperative evaluation of patients with leiomyomas and appropriate selection of patients for intervention. Minimally invasive surgical and non-surgical approaches will be presented. Case presentations will show when medical or radiologicbased approaches may be acceptable. Conventional, robotic and single port laparoscopic approaches as well as laparotomy will be discussed within the context of specific cases. Course Objectives At the conclusion of this course, the participant will be able to: 1) Identify the concepts of selecting patients appropriately for surgery or other intervention; 2) analyze the role of different surgical and non-surgical minimally invasive techniques for the treatment of uterine fibroids; 3) assess techniques to safely perform laparoscopic myomectomy; 4) appraise the surgical approach to single port myomectomy; and 5) identify when myomectomy by laparotomy is indicated.

Faster recovery Faster recovery ‐ ?? Disadvantages/limitations Increased cost and disposable instruments Triangulation is limited with traditional instruments Challenging to perform suturing and fine dissection Longer operative times for some procedures May add value for certain procedures Cholecystectomy Adnexectomy Hysterectomy? – Has been difficult to get gynecologists in USA Robotic surgery may enable more suture intense tasks to be performed g y y p through a single incision IF the only benefit of single incision surgery is cosmetic who should absorb the added cost?

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). US Population Language Spoken at Home California Language Spoken at Home Spanish English Spanish Indo-Euro Asian Other Indo-Euro English Asian Other 19.7% of the US Population speaks a language other than English at home In California, this number is 42.5% 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. 55
