BACKGROUND AND OBJECTIVE: Studies on the role of laparoscopy in secondary or tertiary cytoreduction for recurrent ovarian cancer are limited. Our objective is to describe our preliminary experience with laparoscopic secondary/tertiary cytoreduction in patients with recurrent ovarian, fallopian, and primary peritoneal cancers. METHODS: This is a retrospective analysis of a prospective case series. Women with recurrent ovarian, fallopian tube, or primary peritoneal cancers deemed appropriate candidates for laparoscopic debulking by the primary surgeon(s) were recruited. The patients underwent exploratory video laparoscopy, biopsy, and laparoscopic secondary/tertiary cytoreduction between June 1999 and October 2009. Variables analyzed include stage, site of disease, extent of cytoreduction, operative time, blood loss, length of hospital stay, complications, and survival time. RESULTS: Twenty-three patients were recruited. Only one surgery involved conversion to laparotomy. Seventeen (77.3%) of the patients had stage IIIC disease at the time of their initial diagnosis, and 20 (90.9%) had laparotomy for primary debulking. Median blood loss was 75 mL, median operative time 200 min, and median hospital stay 2 d. No intraoperative complications occurred. One patient (4.5%) had postoperative ileus. Eighteen (81.8%) of the patients with recurrent disease were optimally cytoreduced to 1cm. Overall, 12 patients have no evidence of disease (NED), 6 are alive with disease (AWD), and 4 have died of disease (DOD), over a median follow-up of 14 mo. Median disease-free survival was 71.9 mo. CONCLUSIONS: In a well-selected population, laparoscopy is technically feasible and can be utilized to optimally cytoreduce patients with recurrent ovarian, fallopian, or primary peritoneal cancers.

With the continued expansion of endoscopic techniques and instruments, laparoscopy and minimally invasive techniques are quickly emerging as a feasible alternative to laparotomy in managing adnexal masses and ovarian cancer.Laparoscopy has the potential to completely and successfully treat both benign and malignant adnexal pathology while decreasing unnecessary morbidity among patients. Further advances in technology, techniques, and instruments can only increase this potential.

OBJECTIVES: To describe our experience with laparoscopic primary or interval tumor debulking in patients with presumed advanced ovarian, fallopian tube, or peritoneal cancers. METHODS: This is a retrospective analysis of a prospective case series. Women with presumed advanced (FIGO stage IIC or greater) ovarian, fallopian tube, or primary peritoneal cancers deemed appropriate candidates for laparoscopic debulking by the primary surgeon(s) were recruited. RESULTS: The study comprised 32 patients who underwent laparoscopic evaluation. Seventeen underwent total laparoscopic primary or interval cytoreduction, with 88.2% optimal cytoreduction. Eleven underwent diagnostic laparoscopy and conversion to laparotomy for cytoreduction, with 72.7% optimal cytoreduction. Four patients had biopsies, limited cytoreduction, or both. In the laparoscopy group, 9 patients have no evidence of disease (NED), 6 are alive with disease (AWD), and 2 have died of disease (DOD), with mean follow-up time of 19.7 months. In the laparotomy group, 3 patients are NED, 5 are AWD, and 3 are DOD, with mean follow-up of 25.8 months. Estimated blood loss and length of hospital stay were less for the laparoscopy group (P=0.008 and P=0.03), while operating time and complication rates were not different. Median time to recurrence was 31.7 months for the laparoscopy group and 21.5 months for the laparotomy group (P=0.3). CONCLUSIONS: Laparoscopy can be used for diagnosis, triage, and debulking of patients with advanced ovarian, fallopian tube, or primary peritoneal cancer and is technically feasible in a well-selected population

The objectives of this article were to review the published scientific literature about robotics and its application to gynecologic oncology to date and to summarize findings of this advanced computerenhanced laparoscopic technique. Relevant sources were identified by a search of PUBMED from January 1950 to January 2009 using the key words Robot or Robotics and Cervical cancer, Endometrial cancer, Gynecologic oncology, and Ovarian cancer. Appropriate case reports, case series, retrospective studies, prospective trials, and review articles were selected. A total of 38 articles were identified on the subject, and 27 were included in the study. The data for gynecologic cancer show comparable results between robotic and laparoscopic surgery for estimated blood loss, operative time, length of hospital stay, and complications. Overall, there were more wound complications with the laparotomy approach compared with laparoscopy and robotic-assisted laparoscopy. There were more lymphocysts, lymphoceles, and lymphedema in the robotic-assisted laparoscopic group compared with the laparoscopy and laparotomy groups in patients with cervical cancer. Infectious and lung-related morbidity, postoperative ileus, and bleeding or clot formation were more commonly reported in the laparotomy group compared with the other 2 cohorts in patients with endometrial cancer. Computer-enhanced technology may enable more surgeons to convert laparotomies to laparoscopic surgery with its associated benefits. It seems that in the hands of experienced laparoscopic surgeons, final outcomes are the same with or without use of the robot. There is good evidence that robotic surgery facilitates laparoscopic surgery, with equivalent if not better operative time and comparable surgical outcomes, shorter hospital stay, and fewer major complications than with surgeries using the laparotomy approach

Laparoscopy was used for a second-look assessment in ovarian cancer patients back in the 1970s. However, it is only with the advent of new developments in equipment in the late 1980s and early 1990s along with the vision of pioneers in laparoscopic surgery that has made operative laparoscopy in gynecologic oncology feasible. Laparoscopy has multiple benefits in the cancer patients, including image magnification to visualize metastatic or recurrent disease and improved dissection in challenging areas such as the paravesical and pararectal spaces. There is limited bleeding from small vessels because of the pressure from pneumoperitoneum, decreased hospital stay, and rapid recovery. Postoperative chemotherapy or radiation can be initiated earlier, and radiation complications from bowel adhesions are minimized. Significant progress has been made in the last 2 decades in gynecologic malignancy. In this study, the application of laparoscopy in cervical, endometrial, and ovarian cancer will be presented

OBJECTIVE: To report the novel technique of periumbilical ultrasound-guided saline infusion (PUGSI). DESIGN: Prospective study of two noninvasive diagnostic tests to detect obliterating subumbilical adhesions. SETTING: Tertiary care center. PATIENT(S): One hundred fifty patients were included in the study. Patients without risk factors for adhesions were used as a control group (n = 38), whereas the study group had risk factors for intra-abdominal adhesions (n = 112). INTERVENTION(S): Preoperative examination with the visceral slide and the PUGSI. MAIN OUTCOME MEASURE(S): The presence of obliterating subumbilical adhesions in the high-risk patient and the ability of the PUGSI to detect them preoperatively. RESULT(S): There were no obliterating umbilical adhesions in the control group. The prevalence of obliterating umbilical adhesions in the risk group was 3.6%. The visceral slide test had an accuracy of 96.4%, a sensitivity of 50%, and a specificity of 98.1%, with a negative predictive value of 98.1% and a positive predictive value of 50%. The PUGSI test was able to detect all cases of obliterating subumbilical adhesions, demonstrating sensitivity and specificity of 100%. CONCLUSION(S): The PUGSI test has excellent negative and positive predictive values and is useful in determining patients who have obliterating subumbilical adhesions. Use of both tests preoperatively appears to be helpful in identifying patients at risk for visceral injury during laparoscopic surgery

BACKGROUND: An initial presentation of inguinal metastasis in primary fallopian tube cancer in an asymptomatic patient is uncommon. All previously described palpable lymphadenopathies in fallopian tube cancer have been associated with widely disseminated intra-abdominal disease. CASE: This is the first case of inguinal node metastasis from fallopian tube cancer in a 72-year-old asymptomatic patient with a previous hysterectomy with no evidence of intra-abdominal disease. The metastasis was detected in the contralateral inguinal area. CONCLUSION: Fallopian tube cancer can present with inguinal metastasis, although this is an uncommon occurrence. A high index of suspicion must be maintained, especially in asymptomatic patients with negative imaging studies

OBJECTIVE: Intrinsically poor maternal adaptation to pregnancy and dysregulated processes have been postulated to occur as a consequence of an immune response to the feto-placental unit as 'foreign' material. The aim of our study was to compare placental pathology and pregnancy outcomes of in vitro fertilization (IVF) pregnancies conceived by donor oocytes with those conceived by non-donor oocytes. STUDY DESIGN: We conducted a retrospective, case-control study on 91 placentas from IVF pregnancies (36 from donor oocytes and 55 from non-donor cycles). All placentas were examined by a single pathologist for signs indicative of an immune response, including chronic villitis, chronic deciduitis, increased perivillous fibrin, ischemic change/infarction, decidual vasculopathy, increased syncytial knots, intervillous thrombi, and retroplacental hematomas. RESULTS: Placentas from donor cycles were significantly more likely to demonstrate certain pathologic findings: chronic villitis (P<0.001), chronic deciduitis (P=0.034), increased perivillous fibrin (P=0.001), ischemic change/ infarction (P=0.001), and intervillous thrombi (P =0.008). There was no statistical significance with respect to decidual vasculopathy, increased syncytial knots, or retroplacental hematomas. CONCLUSION: Pathologic evidence of an immune-mediated process is much more pronounced in donor oocyte IVF pregnancies compared to non-donor cycles. Clinical implications of these findings have yet to be determined

OBJECTIVE: The relationship between amniotic fluid volume and gestational age has been described previously. The association of body weight and urine output has been observed in human neonates. Our goal was to assess the correlation of the amniotic fluid index (AFI) with estimated fetal weight (EFW) in the third trimester. METHODS: We conducted a retrospective observational study on 426 pregnant women with singleton gestations who were referred to our unit for sonographic evaluation in the third trimester. The AFI, EFW, and EFW percentile corrected for gestational age were evaluated. The sonographic examinations were stratified into 3 gestational age categories: 28 through 33.9 weeks, 34 through 37.9 weeks, and 38 weeks and later. Maternal and fetal outcome variables were collected from medical records. Linear regression, Mann-Whitney U, and Kruskal-Wallis tests were used for statistical analysis. RESULTS: There was no significant relationship between the AFI and EFW in the entire group of patients (R = 0.08; P = .096). There was a significant relationship between the AFI and EFW after 38 weeks' gestation (R = 0.30; P = .003). In addition, in female fetuses the EFW percentile correlated with higher AFI values at all gestational ages (R = 0.31; P < .001); this, however, was not observed in male fetuses. CONCLUSIONS: There is no relationship between the AFI and EFW during the third trimester, although a positive relationship between the AFI and EFW was noted late in gestation. In pregnancies with female fetuses, the AFI was positively associated with EFW percentile before 38 weeks' gestation
