The aim of this study is to report recurrence-free and overall survival for women with endometrial adenocarcinoma who were surgically staged using robotic-assisted laparoscopy.A retrospective chart review was performed for all consecutive endometrial adenocarcinoma patients surgically staged with robotic-assisted laparoscopy at the University of North Carolina Hospital from 2005 to 2010. Demographic data, 5-year survival, and recurrence-free intervals were analyzed. Statistical analysis using Chi-square, t-test, and Kaplan-Meier curves were performed with SAS software. Study results were compared to endometrial cancer statistics from the Surveillance Epidemiology and End Results database from the National Cancer Institute.A total of 499 patients were identified and included in the study. Recurrence-free intervals after robotic-assisted surgical staging were 85.2% for stage IA, 80.2% for stage IB, 69.8% for stage II, and 69% for stage III. Projected 5-year survival was 88.7% for all patients included in the study. Nearly 82% of cases were endometrioid adenocarcinoma, with papillary serous, clear cell or mixed histology comprising 17.4% of cases. Median follow up time was 23 months, with a range of 0 to 80 months. Among stage IA, IB, II, and III patients, projected overall survival was 94.2%, 85.9%, 77.4%, and 68.6%, respectively.The results from this study demonstrate that robotic-assisted surgical staging for endometrial cancer does not adversely affect rates of recurrence or survival. These findings provide further evidence that robotic-assisted laparoscopic surgical staging is not associated with inferior results when compared to laparotomy or traditional laparoscopy.Copyright © 2012 Elsevier Inc.

Minimally invasive surgery continues to transform the field of gynecologic oncology and has now become the standard of care for many early-stage malignancies. The proven benefits of minimally invasive surgery are driving the rapid introduction and dissemination of novel technologies and the increasing ability to perform even the most complex procedures less invasively. In this article, we will review the current literature on traditional multiport laparoscopy, robotic-assisted laparoscopy, laparoendoscopic single-site surgery as well as robotic-assisted laparoendoscopic single-site surgery, with a specific focus on their role in the treatment of gynecologic malignancies.

Elderly endometrial cancer (EEC) patients represent a challenging clinical situation because of the increasing number of clinical morbidities. In this setting of patients, minimally invasive surgery (MIS) has been shown to improve surgical and clinical outcomes. The aim of this study was to evaluate the peri-operative and oncological outcomes of EEC patients who had undergone laparoscopic (LS) or robotic surgery (RS).

Laparoendoscopic single-site (LESS) surgery has been established for various procedures. Shortcomings of LESS surgery include loss of triangulation, instrument collisions, and poor ergonomics, making advanced laparoscopic tasks especially challenging. We compared a LESS system with a robotic single-site surgery platform in performance of a suturing and knot-tying task under clinically simulated conditions.Each of five volunteer minimally invasive surgeons was tasked with suturing a 5 cm longitudinal enterotomy in porcine small intestine with square knots at either end, using a laparoendoscopic or da Vinci robotic single-site surgery platform, within a 20 min time limit. A saline leak test was then performed. Each surgeon performed the task twice using each system. The time to completion of the task and presence of a leak were noted. Fisher's exact test was used to compare the overall completion rate within the defined time limit, and a Wilcoxon rank test was used to compare the specific times to complete the task. A p value of <0.05 was considered significant.All surgeons were able to complete the task on the first try within 20 min using the robot system; 60% of surgeons were able to complete it after two attempts using the LESS surgery system. Time to completion using the robot system was significantly shorter than the time using the standard LESS system (p < 0.0001). There were no leaks after closure with the robot system; the leak rate following the standard LESS system was 90%.Surgeons demonstrated significantly better suturing and knot-tying capabilities using the robot single-site system compared to a standard LESS system. The robotic system has the potential to expand single-site surgery to more complex tasks.

妇科恶性肿瘤易发生淋巴结转移。盆腔、腹主动脉旁及腹股沟区域是最常发生转移的部位。大多数妇科恶性肿瘤手术需行淋巴结切除或活检，但是目前对于盆腔、腹主动脉旁及腹股沟区域淋巴结解剖命名尚不规范，淋巴转移的常见途径尚未充分阐明，常见恶性肿瘤的淋巴结转移规律亦有争议。文章针对该问题进行探讨。

Background: The oncological outcome of surgery for the treatment of pelvic malignancies can be improved by performing pelvic lymphonodectomy. However, the extent and regions of lymph node harvest are debated and require profound knowledge of anatomy in order to avoid collateral damage. Methods: The embryological development and topographic anatomy of pelvic compartments in relation to pelvic lymphonodectomy for rectal, uterine, and prostate cancer are reviewed. Based on pre-dissected anatomical specimens, lymph node regions and drainage routes of the posterior and urogenital pelvic compartments are described in both genders. Anatomical landmarks are highlighted to identify structures at risk of injury during pelvic lymphonodectomy. Results: The ontogenesis of urogenital and anorectal compartments and their lymphatic supply are key factors for adequate lymphonodectomy, and have led to compartment-based surgical resection strategies. However, pelvic lymphonodectomy bears the risk of injury to somatic and autonomic nerves, vessels, and organs, depending on the regions and extent of surgery. Conclusion: Embryologically defined, compartment-based resection of pelvic malignancies and their lymphatic drainage routes are based on clearly delineated anatomical landmarks, which permit template-oriented pelvic lymphonodectomy. Comprehensive knowledge of pelvic anatomy, the exchange of surgical concepts between specialties, and minimally invasive techniques will optimize pelvic lymphonodectomy and reduce complications.

Robotic surgery has been approved as an alternative to laparoscopy to improve surgical outcomes. There is neither a consensus nor a systematic assessment of the literature about the superiority of the robotic approach over the laparoscopic one for sentinel lymph node (SLN) biopsy in endometrial carcinoma (EC) women. Therefore, a systematic review and meta-analysis was performed to compare the laparoscopic and robotic approaches for SLN biopsy in EC patients. Five electronic databases were queried from their inception to May 2022 for peer-reviewed studies, comparing such approaches in SLN biopsy in EC patients. The rate of detected SLN, dissected SLN, intraoperative and postoperative complications, conversion to laparotomy, number of dissected SLN, and SLN identification and dissection time were compared between the laparoscopic and robotic approaches for SLN biopsy in EC patients. Odds ratios with 95% confidence intervals were calculated when possible. Two studies with 660 EC women (364 who had undergone laparoscopy, and 296 who had robotic surgery) were included. No assessed outcome showed significant differences between the two approaches. In conclusion, the laparoscopic and robotic approaches for SLN biopsy in EC patients appeared to not differ, in terms of SLN detection, intraoperative and postoperative complications, conversion to laparotomy, number of dissected SLN, and SLN identification and dissection time.
