Objective: To compare the incidence of venous thromboembolism (VTE) before and after the implementation of standardized extended duration prophylaxis guidelines in women undergoing laparotomy for gynecologic cancer., Methods: In October 2009, departmental practice guidelines were implemented for VTE prevention. Patients undergoing laparotomy for gynecologic cancer were started on low molecular weight heparin (LMWH) within 24h of surgery and it was continued for a total of 28 days postoperatively. The incidence of VTE diagnosed within 30 and 90 days of surgery was determined and compared to a historic cohort of patients who underwent surgery prior to implementation of the guidelines., Results: The incidence of VTE within 30 days of surgery decreased from 2.7% (8/300) to 0.6% (2/334) following implementation of VTE prevention guidelines (78% reduction, p=0.040). However, when the pre and post-guideline implementation groups were compared for the development of VTE within 90 days of surgery, there was no significant difference (11/300 (3.7%) vs. 10/334 (3.0%) respectively, p=0.619). The median time between surgery and VTE diagnosis was 12 days in the pre-guideline implementation group, compared with 57 days in the post-guideline implementation group (p=0.012)., Conclusion: Patients receiving extended duration LMWH were found to have significantly lower rates of VTE within 30 days of surgery when compared with similar patients who did not receive extended duration LMWH. However, this effect was not sustained when the groups were compared for VTE diagnosis within 90 days of surgery. Additional study is needed to further reduce long-term VTE rates in this high-risk population., (Copyright © 2012 Elsevier Inc. All rights reserved.)

Background: The aim of this study was to evaluate single-port laparoscopy (SPL) for the surgical treatment of presumed early-stage endometrial cancer and to compare surgical outcomes to laparoscopy and robotics., Methods: A multi-institutional, matched retrospective cohort study was performed. All patients with clinical stage I or occult stage II endometrial cancer who underwent SPL hysterectomy, bilateral salpingo-oophorectomy +/- lymphadenectomy from April 2009 to September 2010 were identified. Outcomes were compared with patients matched by age, body mass index (BMI), tumor histology, and grade, who underwent laparoscopy or robotic surgery. Data was analyzed using Kruskal-Wallis 1-way analysis of variance and chi-square test for frequency data. A P value of <.05 was considered significant., Results: A total of 90 matched patients (30 SPL, 30 LSC, and 30 robotic) were included in the study. There were no significant differences in median operating time or estimated blood loss between the 3 groups. The median number of pelvic lymph nodes obtained was significantly higher in the robotic (17.0 [8-36] and SPL group (16.0 [11-21]) compared with the laparoscopy group (13.0 [3-18]) P = .04. However, there was no significant difference in the median number of para-aortic nodes obtained between the 3 groups. There was no significant difference between the groups in length of hospital stay, comorbid conditions, complication rates, or operative times., Conclusions: Our findings suggest SPL surgery for endometrial carcinoma is feasible with similar operating times, hospital length of stay, complication rates, and estimated blood loss when compared with laparoscopy and robotics.

Background: Women with the Lynch syndrome (hereditary nonpolyposis colorectal cancer) have a 40 to 60 percent lifetime risk of endometrial cancer and a 10 to 12 percent lifetime risk of ovarian cancer. The benefit of prophylactic gynecologic surgery for women with this syndrome has been uncertain. We designed this study to determine the reduction in the risk of gynecologic cancers associated with prophylactic hysterectomy and bilateral salpingo-oophorectomy in women with the Lynch syndrome., Methods: Three hundred fifteen women with documented germ-line mutations associated with the Lynch syndrome were identified. Women who had undergone prophylactic hysterectomy (61 women) and women who had undergone prophylactic bilateral salpingo-oophorectomy (47 women) were matched with mutation-positive women who had not undergone the procedure in question (210 women for the analysis of endometrial cancer and 223 for the analysis of ovarian cancer). Women who had undergone prophylactic surgery and their matched controls were followed from the date of the surgery until the occurrence of cancer or until the data were censored at the time of the last follow-up visit., Results: There were no occurrences of endometrial, ovarian, or primary peritoneal cancer among the women who had undergone prophylactic surgery. Endometrial cancer was diagnosed in 69 women in the control group (33 percent), for an incidence density of 0.045 per woman-year, yielding a prevented fraction (the proportion of potential new cancers prevented) of 100 percent (95 percent confidence interval, 90 to 100 percent). Ovarian cancer was diagnosed in 12 women in the control group (5 percent), for an incidence density of 0.005 per woman-year, yielding a prevented fraction of 100 percent (95 percent confidence interval, -62 to 100 percent)., Conclusions: These findings suggest that prophylactic hysterectomy with bilateral salpingo-oophorectomy is an effective strategy for preventing endometrial and ovarian cancer in women with the Lynch syndrome., (Copyright 2006 Massachusetts Medical Society.)
