목적: To evaluate the feasibility of robot-assisted laparoscopic myomectomy in multiple myomas over 10 in number and to compare outcomes with open myomectomy. 방법: This study is a retrospective chart review of 216 patients who underwent robot assisted laparoscopic myomectomy by a single operator at St. Mary's Fibroid Center in Seoul between October 1, 2010 and January 31, 2014; in the selected patients, 10 or more uterine myomas were removed. We reported the characteristics of the removed myomas including the with maximum diameter of the myomas, the sum of the diameter of each myoma, and the types of the combined surgeries. we organized surgical outcomes that were measured including the operative time, estimated intraoperative blood loss, length of hospital stay, and perioperative complications. And we compared these surgical outcomes with cases of open myomectomy. 결과: A total of 13 women underwent the removal of 10 or more uterine myomas by robotics. The patient age was 37.6±3.6 years, and all of the patients were nulliparous. The operation time was 389.8±100.6 min. The number of removed myomas for each case was 13.1±3.8 (range 10-20). The myoma with the maximum diameter was 6.5±0.7 centimeters (range 5.0-8.0 centimeters). The sum of the diameters was 34.9 ±9.6 centimeters (range 20.0-54.5 centimeter. The Estimated blood loss during operation was 219.2±158 milliliter. . The postoperative hospital stay was 2.6±0.6 days. Compared to laparotomic adenomyomectomy, robotic surgery has strengths that enables less blood loss, shorter hospital stay and decreasing risk of blood transfusion although it takes more operation time. 결론: This report is the first to describe the feasibility of robot-assisted laparoscopic myomectomy in multiple myomas over 10 in number. In robot- assisted laparoscopic myomectomies, supplementary techniques including preoperative MRI assessment, intraoperative sonographic navigation, and palpation by an assistant to localize the myomas are helpful in overcoming the absence of haptic perception. This technique is considered to be an alternative to laparotomy for more than 10 myomas.

Development of therapeutic technology through analysis of growth factor of myoma
( Jungyoon Park ),( Youngsin Han ),( Hyejin Hwang ),( Suhyun Shim ),( Yoon Jee Cheung ),( Hyun Hee Cho ),( Jang Heub Kim ),( Mee Ran Kim ) 대한산부인과학회 2018 대한산부인과학회 학술대회 Vol.104 No.-
Objective: The purpose of this study was to compare the level of expression of various growth factors in myoma and to investigate the effect of growth factor inhibitor and to compare the effect of conventional regimens. Methods: The expression levels of growth factors in normal myometrium and myoma were compared by immunohistochemical staining. After primary culture of normal myometrial cells and myoma cells, cell viability was confirmed by treatment with 100 nM Ulipristal acetate (UPA) and Mifepristone (RU486) for 48 hours. Western blot analysis was performed to determine the protein expression of each of these growth factors. Cell viability was determined by treatment with 10uM TGF inhibitor(LY364947) and 5uM VEGF inhibitor(Axitinib) for 24 hours in cultured normal myometrial cells and myoma cells. Results: Immunohistochemical staining revealed that TGF expression was 20% in normal myometrium and 60% in myoma. VEGF expression was 1% in normal myometrium and 16% in myoma respectively. Cell viability was the most significant decrease with 58.59% mifepristone treatment in myoma tissue, and 57.20% in normal myometrium with UPA treatment. In the protein expression, EGF was significantly increased by 80% and IGF was significantly increased by 250% when UPA treated to normal myometrial cells. The expression of VEGF was decreased by 70% when Mifepristone treated to myoma cells. In normal myometrial cell, cell viability was significantly decreased by 60% of the TGF inhibitor treated cells and by 70% of the VEGF inhibitor treated cells. Cell viability of myoma cells was significantly decreased by 27.69% treated with TGF inhibitor and 27.34% treated with VEGF inhibitor. Conclusion: In myoma, TGF was the most expressed among the various growth factors, and VEGF was next increased to be expressed. The administration of inhibitor significantly inhibited the growth of myoma cells, and the suppressive effect was significantly greater than that of conventional drug therapy.
