M-TRAP: Safety and performance of metastatic tumor cell trap device in advanced ovarian cancer patients.

OBJECTIVE: Despite radical surgery and chemotherapy, most patients with ovarian cancer die due to disease progression. M-Trap is an implantable medical device designed to capture peritoneal disseminated tumor cells with the aim to focalize the disease. This trial analyzed the safety and performance of the device. METHODS: This first-in-human prospective, multi-center, non-blinded, single-arm study enrolled 23 women with high-grade serous advanced ovarian cancer. After primary or interval debulking surgery, 3 M-Trap devices were placed in the peritoneum of the abdominal cavity. 18-months post-implantation or at disease progression, devices were initially removed by laparoscopy. The primary safety endpoint was freedom from device and procedure-related major adverse events (MAEs) through 6-months post-implantation compared to an historical control. The primary performance endpoint was histopathologic evidence of tumor cells capture. RESULTS: Only one major adverse event was attributable to the device. 18 women were free of device and procedure related MAEs (78.3%). However, the primary safety endpoint was not achieved (p = 0.131), primarily attributable to the greater surgical complexity of the M-Trap patient population. 62% of recurrent patients demonstrated tumor cell capture in at least one device with a minimal tumor cell infiltration. No other long-term device-related adverse events were reported. The secondary performance endpoint demonstrated a lack of disease focalization. CONCLUSIONS: The M-Trap technology failed to meet its primary safety objective, although when adjusted for surgical complexity, the study approved it. Likewise, the devices did not demonstrate the anticipated benefits in terms of tumor cell capture and disease focalization in recurrent ovarian cancer.

Voiding recovery after radical parametrectomy in cervical cancer patients: An international prospective multicentre trial - SENTIX.

OBJECTIVE: Voiding dysfunctions represent a leading morbidity after radical hysterectomy performed in patients with early-stage cervical cancer. The aim of this study was to perform ad hoc analysis of factors influencing voiding recovery in SENTIX (SENTinel lymph node biopsy in cervIX cancer) trial. METHODS: The SENTIX trial (47 sites, 18 countries) is a prospective study on sentinel lymph node biopsy without pelvic lymphadenectomy in patients with early-stage cervical cancer. Overall, the data of 300 patients were analysed. Voiding recovery was defined as the number of days from surgery to bladder catheter/epicystostomy removal or to post-voiding urine residuum ≤50 mL. RESULTS: The median voiding recovery time was three days (5th-95th percentile: 0-21): 235 (78.3%) patients recovered in <7 days and 293 (97.7%) in <30 days. Only seven (2.3%) patients recovered after >30 days. In the multivariate analysis, only previous pregnancy (p = 0.033) and type of parametrectomy (p < 0.001) significantly influenced voiding recovery >7 days post-surgery. Type-B parametrectomy was associated with a higher risk of delayed voiding recovery than type-C1 (OR = 4.69; p = 0.023 vs. OR = 3.62; p = 0.052, respectively), followed by type-C2 (OR = 5.84; p = 0.011). Both previous pregnancy and type C2 parametrectomy independently prolonged time to voiding recovery by two days. CONCLUSIONS: Time to voiding recovery is significantly related to previous pregnancy and type of parametrectomy but it is not influenced by surgical approach (open vs minimally invasive), age, or BMI. Type B parametrectomy, without direct visualisation of nerves, was associated with longer recovery than nerve-sparing type C1. Importantly, voiding dysfunctions after radical surgery are temporary, and the majority of the patients recover in less than 30 days, including patients after C2 parametrectomy.

Laparoscopic Power Morcellation: Techniques to Avoid Tumoral Spread.

STUDY OBJECTIVE: To show 3 different techniques for achieving an endobag morcellation without adding extra time and cost to the surgery. DESIGN: Stepwise demonstration of the 3 techniques with narrated video footage. SETTING: Morcellation is a useful procedure for fragmenting and extracting specimens during laparoscopic surgery without the need to perform a laparotomy. Patients who otherwise would not be eligible for minimally invasive surgery (i.e., those with a large uterus or myomas) could benefit from laparoscopic advantages. However, morcellation has a major limitation: the risk of dissemination of unsuspected malignancies. In 2017, the Food and Drug Administration released an updated assessment of the use of laparoscopic power morcellators for treatment of leiomyomas. A total of 23 studies were included in the analysis, and 20 studies (90 910 women) contributed to the estimated prevalence of leiomyosarcoma at the time of surgery for presumed leiomyomas. Depending on the modeling methodology used, the estimated prevalence of uterine sarcoma was 1 in 305 to 1 in 360 women, and for leiomyosarcoma, the estimated prevalence was 1 in 570 to 1 in 750 women [1]. Currently available evidence has suggested that if an undiagnosed uterine malignancy is intra-abdominally morcellated, there is a risk of intraperitoneal dissemination of the disease [2]. Therefore, the European Society of Gynecological Oncology emitted a statement in 2016 recommending avoiding morcellation if there is any suspicion of sarcoma and using endobag containers for morcellation of the surgically removed uterine myomas [3]. In addition, in the United States, the Food and Drug Administration recommends performing laparoscopic power morcellation for myomectomy or hysterectomy only with a tissue containment system, legally marketed in the United States [4]. INTERVENTIONS: There are several techniques described in the literature for contained uterine myomas morcellation [5]. In this video, we present 3 of them: First, an indirect-view morcellation is described. In this technique, we placed the myoma in the bag and exteriorize it through one of the trocars. Once outside the abdomen, we placed the morcellator through the bag opening and did the morcellation inside the bag while checking through the umbilicus camera. Special attention must be paid to avoid any damage to the bag because the visualization is limited in this technique. Second, a direct-view technique is described, in which we exteriorized the opening of a 15-mm bag through the suprapubic trocar and a closed end of the bag through the umbilicus. We made a hole in the umbilicus end of the bag and introduced the camera trocar through it. Once done, we introduced the morcellator through the opening and the camera in the umbilicus port. Third, a single-port-contained morcellation is explained. The bag was exteriorized through the umbilicus, and a skin retractor was placed. A glove was placed outside the retractor to isolate the bag. Once placed, 2 of the fingers were opened and used as trocars (one for the morcellator and the other for a 30° camera). After using this technique, the scope should be replaced to minimize the risk of contamination. The following are possible limitations of each technique: in the indirect-view technique, owing to the limited visualization, the surgeon must pay special attention to avoid tearing the bag while morcellating the specimen. In the direct-view technique method, the surgeon needs to ensure the proper closure of the bag before removing it from the abdomen to avoid possible dissemination risk. Finally, in the single-port technique, the surgeon must have previous experience in this type of approach, minimizing the risk of contamination by changing the scope after the morcellation process. CONCLUSION: Laparoscopic power morcellation may provide several benefits for our patients, when performing a hysterectomy or a multiple myomectomy. We presented 3 different and feasible techniques for laparoscopic power morcellation using an endobag container.

COVID-19: gynecologic cancer surgery at a single center in Madrid.

OBJECTIVES: While numerous medical facilities have been forced to suspend oncological surgery due to system overload, debate has emerged on using non-surgical options on cancer cases during the pandemic. The goal of our study was to analyze, in a retrospective cohort study, the results of gynecological cancer surgery and evaluate postoperative complications in a single center in one of the most affected areas in Europe. METHODS: We retrospectively analyzed the records of patients who were referred between March 2020 and May 2020 for primary surgical treatment of breast, endometrial, ovarian, cervical, or vulvar cancer. RESULTS: The study included a total of 126 patients. Median age was 60 years (range 29-89). Patients were referred with breast (76/126, 60.3%), endometrial (29/126, 23%), ovarian (14/126, 11.1%), cervical (5/126, 4%), or vulvar cancer (2/126, 1.6%). Polymerase chain reaction (PCR) test for detection of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) was only conducted in 50% of cases due to the low availability of tests during the first phase of our study, and was indicated only in suspected cases according to the healthcare authorities' protocol. Median hospital stay was 1 day (range 0-18). Excluding breast surgery, laparoscopy was the most used procedure (43/126, 34.1%). 15 patients had a postoperative complication (15/126, 11.9%); only in 2 patients (2/15 13.3%) were there reports of Clavien-Dindo grade 3 or 4 complications. 6 patients tested positive for COVID-19 following a PCR diagnostic test, and these surgeries were cancelled. CONCLUSIONS: Adequate protective measures in the setting of COVID-19 free institutions enabled the continuity of cancer surgery without significant compromise of the safety of patients or healthcare workers.

Genomic Profiling of Uterine Aspirates and cfDNA as an Integrative Liquid Biopsy Strategy in Endometrial Cancer.

The incidence and mortality of endometrial cancer (EC) have risen in recent years, hence more precise management is needed. Therefore, we combined different types of liquid biopsies to better characterize the genetic landscape of EC in a non-invasive and dynamic manner. Uterine aspirates (UAs) from 60 patients with EC were obtained during surgery and analyzed by next-generation sequencing (NGS). Blood samples, collected at surgery, were used for cell-free DNA (cfDNA) and circulating tumor cell (CTC) analyses. Finally, personalized therapies were tested in patient-derived xenografts (PDXs) generated from the UAs. NGS analyses revealed the presence of genetic alterations in 93% of the tumors. Circulating tumor DNA (ctDNA) was present in 41.2% of cases, mainly in patients with high-risk tumors, thus indicating a clear association with a more aggressive disease. Accordingly, the results obtained during the post-surgery follow-up indicated the presence of ctDNA in three patients with progressive disease. Moreover, 38.9% of patients were positive for CTCs at surgery. Finally, the efficacy of targeted therapies based on the UA-specific mutational landscape was demonstrated in PDX models. Our study indicates the potential clinical applicability of a personalized strategy based on a combination of different liquid biopsies to characterize and monitor tumor evolution, and to identify targeted therapies.

Lack of Survival Benefit of Para-Aortic Lymphadenectomy in Advanced Cervical Cancer.

INTRODUCTION: The presence of positive para-aortic lymph nodes in advanced cervical cancer remains the most important prognostic factor for survival and also defines the treatment. Our aim was to define the influence of staging para-aortic lymphadenectomy in patients' survival. MATERIAL AND METHODS: The medical records of 74 patients with advanced cervical cancer (FIGO IIB-IVA) were reviewed. In 31 patients (41.9%), the assessment of lymph nodes was performed with imaging test (group 1) and in 43 (58.1%) within a surgical staging para-aortic lymphadenectomy (group 2). We compared both groups according to stage of disease, treatment, progression-free survival (PFS), and overall survival (OS). RESULTS: The extended-field radiotherapy was performed in 44.2 and 19.4% of patients in surgical and imaging staging group, respectively (p = 0.045). The disease-free survival rate was 17.4 ± 17.4 months in group 1 and 14.4 ± 12.6 months in group 2 (p = 0.456). No differences in OS were found between these 2 groups (p = 0.676). CONCLUSIONS: Despite the higher diagnostic accuracy of surgical staging and the higher number of patient who received extended field radiotherapy, we did not find differences between the overall and PFS rates in both the studied groups. Further prospective study on a higher number of patients would be necessary.

Left Lateral Endosurgical Extraperitoneal Total Hysterectomy with Para-Aortic and Pelvic Lymphadenectomy: A Novel Approach for the Obese Patient with Endometrial Cancer.

STUDY OBJECTIVE: To describe the left lateral extraperitoneal approach to perform complete para-aortic and pelvic lymphadenectomy and transverse total hysterectomy from left to right as a novel approach to treat obese patients with endometrial cancer. Laparoscopic management of obese patients represents a challenge for the gynecologic surgeon. The extraperitoneal approach is technically easier in the obese patient because it naturally creates a bowel-free operative field. DESIGN: A prospective pilot bicentric and descriptive study (Canadian Task Force classification III) evaluating the feasibility and reproducibility of the transverse total hysterectomy and complete lymphadenectomy through left endoscopic extraperitoneal approach in obese patients with endometrial cancer. SETTING: A comprehensive cancer center in Toulouse and a teaching university hospital in Madrid. PATIENTS: Sixteen consecutive overweight or obese patients (body mass index > 25 kg/m2) with high-risk endometrial cancer. INTERVENTIONS: Currently, the left extraperitoneal approach is routinely used to perform complete para-aortic and pelvic lymphadenectomy. It provides direct access to the left ureter and uterine pedicle. This access can be extended to the right side when performing a transverse extrafascial hysterectomy from left to right. The procedure starts from the left extraperitoneal space, where the left uterine artery is sectioned and the vesicovaginal and rectovaginal septa are developed, without opening the peritoneum. Colpotomy is performed from the left to the right side. Once the right ureter is identified, the right uterine artery can be safely transected. Alternatively, the right uterine artery can be sealed and sectioned during the right pelvic lymphadenectomy. At the end of the procedure the peritoneum is opened to complete the surgery. MEASUREMENTS AND MAIN RESULTS: Between May 2015 and February 2016, 16 consecutive obese patients were successfully treated using this technique. Median patient age was 62 years (range, 44-78), and median body mass index was 32.5 kg/m2 (range, 26-42). In 3 cases the right uterine artery was sealed during the right pelvic lymphadenectomy, in 11 cases after completing vaginal opening, and in 2 cases after peritoneal opening. The median operative time was 137.5 minutes (range, 66-260). The median blood loss was 85 mL (range, 0-260), and no blood transfusion was required in any of our 16 patients. No significant complications occurred. CONCLUSION: The full extraperitoneal approach represents an interesting alternative strategy for the surgical treatment of obese patients with high-risk endometrial cancer.

Utility and Actual Use of European and Spanish Guidelines on the Management of Endometrial Cancer Among Gynecologic Oncologists in Spain.

OBJECTIVE: The aim of the study was to analyze the current management of endometrial cancer across Spain and to evaluate the use and applicability of the national and international guidelines. MATERIALS AND METHODS: An electronic 30-question survey was distributed among all Spanish Society of Obstetrics and Gynecology-registered specialists dedicated to gynecologic oncology in Spain by e-mail. Data were collected anonymously and analyzed using SPSS program. RESULTS: One hundred forty-five (17.8%) surveys were collected. Significant differences were observed between tertiary hospitals and secondary or private hospitals in terms of appropriate (according to European Society of Gynaecologic Oncology guidelines) nodal staging in low-risk cases (96 [95%] vs 27 [61.4%], respectively; P < 0.001), appropriate nodal staging in intermediate-risk cases (96 [95%] vs 39 [88.6%], respectively; P = 0.004), appropriate treatment in advanced-stage cases (63 [67.7%] vs 13 [40.6%], respectively; P < 0.001), and surgical treatment of relapses (87 [93.5%] vs 18 [56.3%], respectively; P = 0.004) but nonsignificant in the rate of complete paraaortic lymphadenectomy performance (82 [81.2%] vs 28 [63.6%], respectively; P = 0.056). Similar results have been observed when comparing centers with less than 20 cases per year to centers with more than 40 cases annually, with significant differences in the management of low-risk and intermediate-risk endometrial cancers. CONCLUSIONS: This cross-sectional study demonstrates a broad heterogeneity of care giving between the clinical national and international guidelines and the actual practice in Spain. Although most of the responders refer to base their endometrial cancer management on Spanish and European Society of Gynaecologic Oncology guidelines (64.1%), many discrepancies have been observed, mainly in the management of intermediate-risk cases and follow-up. It may be caused by the lack of consensus on certain points, lack of facilities in lower case load centers, and also due to disagreement or unawareness on the current knowledge.

Utility of Three-Dimensional Ultrasonography to Assess the Position of Essure Tubal Occlusion Device and Its Complications.

BACKGROUND: To determine the utility of three-dimensional (3D) sonography to control the position of hysteroscopic sterilizing device compared to hysterosalpingography (HSG). METHODS: A prospective observational study was carried out on 139 patients who underwent hysteroscopic tubal occlusion method between February 2012 and May 2013. Patients underwent 3D ultrasound scan to control device positioning, and they also underwent HSG as an additional control method. Comparison between both methods was carried out. RESULTS: In all, 17 (12.2%) devices were inserted due to a hydrosalpinx and 122 (87.8%) due to sterilization purposes. In 124 (89.2%) cases, sonography correlated completely to HSG findings. Sonography-positive predictive value was 89.5% to detect correct device positioning. Just 4 (2.8%) patients did not present complete tubal occlusion 3 months after device insertion; one of them presented device expulsion, 2 of them presented previous hydrosalpinx (tubal occlusion was confirmed after 6 months), and the last case rejected to undergo further controls but device seem to be effective. CONCLUSIONS: 3D sonography seems to be effective for the control of sterilization device positioning, but it also detects insertion complications and device migration. Further studies would be required to assess our findings and the role of sonography in case of hydrosalpinx.

Novel Technique for Contained Power Morcellation through Umbilicus with Insufflated Bag.

In April 2014, the US Food and Drug Administration published a safety communication warning of the risk of an unsuspected uterine sarcoma being morcellated during a laparoscopic procedure and therefore advising against the use of power morcellation. These statements have encouraged the scientific community to look for new techniques that allows performing this procedure in a safer way, decreasing the risk of malignant dissemination thorough the abdominal cavity. We describe a new technique for power morcellation using a plastic bag through umbilicus using a latex glove and skin retractor as a single port device. This new procedure was performed in 4 women diagnosed with myomatous uterus. Median age was 40.5 years. No intraoperative complications, conversion to laparotomy or bag rupture occurred. Median surgical time was 195 min and median morcellation time was 48 min. Median in-hospital stay was 4.5 days. This new technique could be an acceptable and feasible alternative for specimen delivery during laparoscopic hysterectomy and myomectomy. However, it is still necessary to increase the number of procedures to assess its safety in case of uterine sarcoma. The video and supplemental contents demonstrate the safety and feasibility of the technique.

Sentinel lymph node mapping in patients with stage I endometrial carcinoma: a focus on bilateral mapping identification by comparing radiotracer Tc99m with blue dye versus indocyanine green fluorescent dye.

PURPOSE: The aim of this study was to compare technetium radiocolloid (Tc99m) + blue dye (BD) versus Indocyanine green (ICG) fluorescent dye in terms of the overall detection rate and bilateral sentinel lymph node (SLN) mapping in patients with endometrial carcinoma. METHODS: Patients from five European centers with apparently confined clinical stage I endometrial cancer were reviewed. A comparison was made between women who received SLN mapping with pelvic and/or aortic lymphadenectomy (LND), and women who underwent SLN algorithm (SA), was also performed between the two groups. RESULTS: Three hundred and forty-two (342) women were involved (147 in the Tc99m + BD group and 195 in the ICG group). The overall detection rate of SLN biopsy was 97.3% (143/147) for women in the Tc99m + BD group and 96.9% (189/195) for women in the ICG group (p = 0.547). The bilateral mapping rate for ICG was 84.1%-significantly higher with respect to the 73.5% obtained with Tc99m + BD (p = 0.007). No differences in overall sensitivity (OS) and overall false negative rate (FNR) were seen between LND and SA (p value = 0.311), whereas the negative predictive value (NPV) was in favor of SA group (p value = 0.030). CONCLUSIONS: In this study, fluorescent mapping using ICG resulted equivalent to the standard combined radiocolloid and BD, but real-time SLN mapping achieves a higher bilateral detection rate. The added value that this fast emerging technology promises to give certainly warrants future studies to further consolidate the advantages there are over the standard technique.

The role of surgery in advanced epithelial ovarian cancer.

Nowadays, the standard management of advanced epithelial ovarian cancer is correct surgical staging and optimal tumour cytoreduction followed by platinum and taxane-based chemotherapy. Standard surgical staging consists of peritoneal washings, total hysterectomy, and bilateral salpingo-oophorectomy, inspection of all abdominal organs and the peritoneal surface, biopsies of suspicious areas or randomised biopsies if they are not present, omentectomy and para-aortic lymphadenectomy. After this complete surgical staging, the International Federation of Gynaecology and Obstetrics (FIGO) staging system for ovarian cancer is applied to determine the management and prognosis of the patient. Complete tumour cytoreduction has shown an improvement in survival. There are some criteria to predict cytoreduction outcomes based on serum biomarkers levels, preoperative imaging techniques, and laparoscopic-based scores. Optimised patient selection for primary cytoreduction would determine patients who could benefit from an optimal cytoreduction and might benefit from interval surgery. The administration of intraperitoneal chemotherapy after debulking surgery has shown an increase in progression-free survival and overall survival, especially in patients with no residual disease after surgery. It is considered that 3-17% of all epithelial ovarian carcinoma (EOC) occur in young women that have not fulfilled their reproductive desires. In these patients, fertility-sparing surgery is a worthy option in early ovarian cancer.

Utility of Laparoscopic Indocyanine Green-Guided Sentinel Node Biopsy in Open Cervical Cancer Surgery.

OBJECTIVE: Multiple tracers have been used to improve lymphatic mapping and to reduce the false-negative rate of the sentinel node detection in gynecologic cancers. Nowadays, 99mTc colloids combined with blue-dye technique is the most extended technique. New alternatives such as the fluorescent indocyanine green and near-infrared fluorescent imaging detection have been introduced in lymphatic mapping staging procedures because of its easier visualization compared with the previous tracers. METHODS: We used the laparoscopic infrared camera for the indocyanine green-guided sentinel node biopsy in a laparotomic radical hysterectomy in a pregnant patient after a cesarean section, with the aim of improving the detection rate of sentinel node biopsy in open surgery. RESULTS: The technique was used in the first patient with accurate detection of sentinel node and no complications during the procedure. CONCLUSIONS: The use of laparoscopic indocyanine green in open surgery may be a useful tool for the detection of sentinel node biopsy.

One-step nucleic acid amplification (OSNA) for the detection of sentinel lymph node metastasis in endometrial cancer.

OBJECTIVE: To evaluate the efficacy of one-step nucleic acid amplification (OSNA) for the diagnosis of sentinel lymph node (SLN) metastasis compared with histopathological examination in patients with endometrial carcinoma. METHODS: A total of 94 SLNs from 34 patients with endometrial carcinoma were enrolled. The central 1-mm portion of each node was subjected to semi-serial sectioning, sliced at 200-µm intervals and examined by hematoxylin and eosin and cytokeratin 19 (CK19) immunohistochemical staining, and the remaining tissue was analysed by OSNA using CK19 mRNA. The accuracy of the OSNA assay was evaluated based on histopathological diagnosis. RESULTS: Histologically, 89 SLNs were determined to be metastasis negative, and the remaining five SLNs were metastasis positive. Using the breast cancer cutoff value for detecting lymph node metastasis (OSNA criteria for breast cancer, >250copies/µl) the sensitivity of the OSNA assay was 100%; specificity was 87.6%; diagnostic accuracy was 88.3%. Discordant results were recorded for 11 of 94 SLNs. In all 11 cases, a positive result was given by the OSNA assay but not by histopathological examination. In two SLNs from the same patient, histopathological examination revealed the presence of benign epithelial inclusions that were CK19 positive; both SLNs yielded a positive result in the OSNA assay (true-false positive). All remaining nine histologically-negative/OSNA-positive SLNs were classified as micrometastasis (+) by the OSNA assay. CONCLUSION: The OSNA assay shows high sensitivity and specificity, which suggests its utility as a novel tool for the molecular detection of SLN metastasis in patients with endometrial carcinoma.

Validation of a structured intensive laparoscopic course for basic and advanced gynecologic skills training.

OBJECTIVE: To describe and validate a gynecologic laparoscopic-surgery training model. METHODS: The present prospective observational study was conducted at the Minimally Invasive Surgery Centre Jesús Usón, Cáceres, Spain, between January 2011 and June 2013. Novice gynecologists attended a 3-day course including simulation and animal training. Participants' were assessed before and after training using a virtual reality simulator; during training, gynecologists were timed and assessed using an Objective and Structured Assessment of Technical Skills score. The virtual reality simulator-assessed skills were eye-hand coordination, hand-hand coordination, and transference of objects. Participants were asked to rate various elements of the training program using a five-point scale. RESULTS: The study enrolled 21 gynecologists. Participants performed all tasks faster (P<0.001), using fewer movements (P<0.05 for left and right instruments), after receiving training. During participants' final animal and simulator training sessions, completion times were reduced (P<0.001) and assessment scores (P<0.001) increased for all techniques and tasks. Participants considered suturing to be the most useful aspect of the basic-skills training (4.95±0.22); animal training received a higher rating than simulator training for practicing new techniques (4.81±0.40 vs 4.05±0.86) and maintaining skills (4.76±0.54 vs 3.95±0.97). CONCLUSION: Combining proficiency-based physical simulation and animal training models under expert guidance is an efficient model for improving basic and advanced laparoscopic skills. Suturing and animal models were the preferred training components.

Novel technique for the complete staging of endometrial cancer by single-port laparoscopy.

OBJECTIVE: Our aim was to evaluate the feasibility of a novel technique using single-port laparoscopy for the complete surgical staging of endometrial cancer. METHODS: Total hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy and para-aortic lymphadenectomy was performed using a single-port device in two steps: first, a retroperitoneal para-aortic dissection was conducted, followed by a transperitoneal pelvic lymphadenectomy and a total hysterectomy. Conventional laparoscopic instruments were used in all cases. Perioperative details were collected. RESULTS: Four consecutive patients with endometrial cancer underwent single-port laparoscopic staging procedure. All cases were high-risk endometrial cancers (two FIGO stage IA and two IB). Histologic types included three adenocarcinomas and one carcinosarcoma. The median operating time was 280min (ranged 240-320min), and the median length of stay was 3.5days (ranged 3-6days). No complications or conversion to conventional multiport laparoscopy were reported. CONCLUSIONS: Single-port laparoscopic surgical staging for endometrial cancer is a feasible procedure, even when the procedure included a para-aortic lymph node dissection.

Laparoscopic Sentinel Node Biopsy Using Real-time 3-dimensional Single-photon Emission Computed Tomographic Guidance in Endometrial Cancer.

In endometrial cancer, the histopathological analysis of the lymphatic nodes is essential to establish a correct prognosis and tailored adjuvant treatment. It is well-known that patients with early-stage endometrial cancer have a low incidence of nodal disease. In this group, systematic lymphadenectomy is not recommended. To improve the detection rate of sentinel nodes in clinical practice, new techniques are emerging like real-time 3-dimensional single-photon emission computed tomographic (SPECT) imaging. We report our experience using this innovative technique for intraoperative detection of sentinel nodes in endometrial cancer. The real-time 3-dimensional SPECT sentinel node biopsy seems to be feasible and accurate in endometrial cancer although further studies are needed to set the precision and predictive values compared with the current differed SPECT techniques and blue dye techniques.

Pelvic Exenteration in Gynecologic Cancer: La Paz University Hospital Experience.

BACKGROUND: Pelvic exenteration is an ultraradical surgery involving the en bloc resection of the pelvic organs, including the internal reproductive organs, the distal urinary tract (ureters, bladder, urethra), and/or anorectum. It is mainly applied as a salvage surgery for recurrent gynecologic tumors of any origin (vulva, vagina, cervix, uterine, and also ovary). Our aim was to establish the most favorable cases for this type of surgery by means of a review of our institution experience. METHODS: Retrospective analyses of all patients treated with pelvic exenteration for recurrent gynecologic cancer from 2008 to 2014 at La Paz University Hospital. RESULTS: Ten patients underwent pelvic exenteration for recurrent gynecologic cancers including uterine, cervical, vaginal, vulvar, and ovarian cancer. All patients had received prior treatment: surgery, radiotherapy, and/or chemotherapy. Eight patients underwent total pelvic exenteration, one anterior and one posterior pelvic exenteration. Urinary diversions technique consisted of ileal conduits in all cases. Permanent colostomy was performed in all cases. Postoperative complications were related to the urinary diversion in 50% of the cases, to the reconstructive technique in 30%, and to systemic or pelvic infections in 20%. CONCLUSIONS: Despite the high morbidity and mortality rates, pelvic exenteration is feasible, and in selected cases of cancer recurrence is the last possible treatment.

Laparoscopic Removal of an Intramyometrial Fetus After Uterine Curettage.

STUDY OBJECTIVE: To show the removal of an intramyometrial fetus after uterine curettage using laparoscopy as a safe surgical technique that offers excellent results and fewer complications than laparotomy. DESIGN: Presentation of the clinical case and step-by-step explanation of the technique. SETTINGS: Uterine curettage is a frequently performed gynecologic abortion procedure. Dilatation and curettage is considered to be a safe surgical technique, with a low percentage of complications. The most common is uterine perforation, with higher risks in advanced gestational age, retroflexed uterus, or uterine leiomyomas. INTERVENTIONS: After institutional review board approval, we present the case of a 29-year-old women referred to our hospital from another clinic with a suspected uterine perforation after an elective curettage for a 14-week pregnancy. She presented with moderate abdominal pain. Vaginal ultrasound revealed intramyometrial fetal parts on isthmus and right parametrium and minimal free fluid in the pouch of Douglas. A laparoscopic approach was chosen. After a complete revision of the abdominal cavity, the right paravesical space was dissected, confirming no right uterine artery or ureter injury. One cavity was objectified in the posterior leaf of the broad ligament related to a uterine perforation and containing fetal bone parts, which were removed. The myometrial defect and the peritoneum were closed with intracorporeal sutures. The removal of fetal parts was done with a surgical glove thimble. After the procedure, the patient was treated with clindamycin and gentamycin, with a satisfactory recovery. CONCLUSION: The presence of an intramyometrial fetus is not a common complication of curettage. The use of laparoscopy is feasible and offers excellent results and advantages versus laparotomy regarding its treatment.
