INTRODUCTION Robotic surgery has been applied in managing various types of gynecologic cancers. The purpose of this study is to compare the surgical outcomes of robotic surgery, laparoscopy and laparotomy for managing endometrial cancer. METHODS A total of 365 patients received surgical staging for treating IA to IIIC endometrial cancer were(More)
BACKGROUND Currently, benefits of robotic surgery in patients with benign gynecological conditions remain unclear. In this study, we compared the surgical outcome of robotic and laparoscopic total hysterectomies and evaluated the feasibility of robotic surgery in cases with pelvic adhesions or large uterus. MATERIALS AND METHODS A total of 216 patients(More)
BACKGROUND Laparoscopic bipolar coagulation of uterine vessels (LBCUV) has been employed for women with symptomatic uterine myomas, but its effect on subsequent pregnancy has not been characterized. METHODS Four-hundred and twenty-three women entered the study between March 1999 and December 2001. Of these, 142 women (33.6%) were under the age of 40 years(More)
Several cases in which uteruses have been preserved in women with placenta percreta have been reported. We herein report a 38-year-old woman with a history of previous cesarean section who was admitted with lower abdominal pain and vaginal bleeding at 31 weeks of gestation. An urgent exploratory laparotomy revealed active bleeding from the uterine rupture(More)
STUDY OBJECTIVE To evaluate whether laparoscopic bipolar coagulation of uterine vessels (LBCUV) and supracervical amputation improve laparoscopic-assisted vaginal hysterectomy (LAVH). DESIGN Prospective, randomized, longitudinal study (Canadian Task Force classification II-1). SETTING Private practice, university-affiliated hospital. PATIENTS(More)
OBJECTIVE The aim of this study was to compare the outcomes of robotic surgery, laparoscopy, and laparotomy for the surgical treatment of stage IA to IIB cervical cancer. METHODS This retrospective study was carried out in a university-affiliated teaching hospital. A total of 100 women with an initial diagnosis of stage IA to IIB cervical cancer, without(More)
Postpartum hemorrhage (PPH) is a big challenge for obstetricians. Fertility-preserving procedures are encouraged, especially in young women. Bilateral hypogastric (internal iliac) artery ligation, bilateral uterine artery ligation after vaginal delivery or after cesarean delivery, and uterine artery embolization are well documented vascular occlusive(More)
Degenerative changes occur relatively frequently in uterine leiomyomas. Morphologic changes such as necrosis, hyalinization, and alterations in cellularity are described after uterine artery embolization. A modified method to interrupt the uterine blood supply is laparoscopic bipolar coagulation of uterine vessels (LBCUV). Although the success rate is good,(More)
OBJECTIVE The aim of this study was to evaluate the short-term therapeutic outcome of women with symptomatic uterine myomas treated with laparoscopic uterine vessel occlusion (LUVO) or laparoscopic myomectomy (LM). METHODS Ninety-five patients with symptomatic, uncomplicated myomas warranting surgical treatment who expressed a strong desire to retain(More)
Successful fertilization is tightly regulated by capacitation and decapacitation processes. Without appropriate decapacitation regulation, sperm would undergo a spontaneous acrosome reaction which leads to loss of fertilization ability. Seminal plasma is known to negatively regulate sperm capacitation. However, the suppressive mechanisms still remain(More)
