RESUMO
The demand for fertility-sparing surgery (FSS) has increased in the last decade due to increased maternal age, increased incidence of ovarian malignancies in younger patients, and technical advances in surgery. Data on oncological safety and fertility outcomes of patients with ovarian cancer after laparoscopic FSS are sparse, but some retrospective studies have shown that open FSS may be offered to selected patients. We assessed the role of minimally invasive FSS in comparison with radical surgery (RS) in terms of oncological safety and reproductive outcomes after FSS in this multicenter study. Eighty patients with FIGO stage I/II ovarian cancer treated with laparoscopic FSS or RS between 01/2000 and 10/2018 at the participating centers (comprehensive gynecological cancer centers with minimally invasive surgical expertise) were included in this retrospective analysis of prospectively kept data. Case-control (n = 40 each) matching according to the FIGO stage was performed. Progression-free survival [150 (3-150) and 150 (5-150) months; p = 0.61] and overall survival [36 (3-150) and 50 (1-275) months; p = 0.65] did not differ between the FSS and RS groups. Eight (25.8%) women became pregnant after FSS, resulting in seven (22.5%) deliveries; three (37.5%) patients conceived after in vitro fertilization, and five (62.5%) conceived spontaneously. Laparoscopic FSS seems to be applicable and oncologically safe for patients with early-stage ovarian cancer, with adequate fertility outcomes.
RESUMO
Incentivized experiments in which individuals receive monetary rewards according to the outcomes of their decisions are regarded as the gold standard for preference elicitation in experimental economics. These task-related real payments are considered necessary to reveal subjects' "true preferences." Using a systematic, large-sample approach with three subject pools of private investors, professional investors, and students, we test the effect of task-related monetary incentives on risk preferences in four standard experimental tasks. We find no significant differences in behavior between and within subjects in the incentivized and non-incentivized regimes. We discuss implications for academic research and forions in the field.

RESUMO
BACKGROUND: Live surgery events serve as a valuable tool for surgical education, but also raise ethical concerns about patient safety and professional performance. In the present study, we evaluate the technical feasibility and didactic benefits of live surgery on body donors compared to real patients. METHODS: A live surgery session performed on a body donor's cadaver embalmed in ethanol-glycerol-lysoformin was integrated into the live surgery program presented at a major gynecological convention of minimally invasive surgery. Surgical procedures carried out in real patients were paralleled in the body donor, including the dissection and illustration of surgically relevant anatomical landmarks. A standardized questionnaire was filled by the participants (n = 208) to evaluate the appropriateness, effectiveness, and benefits of this novel concept. RESULTS: The live surgery event was appreciated as a useful educational tool. With regard to the use of body donors, authenticity was rated high (85.5%), and the overall value of body donors for surgical education and training was rated very high (95.0%). The didactic benefit of simultaneous operations performed on body donors and real patients was considered particularly useful (95.5%), whereas complete replacement of real patients by body donors was not favored (14.5%). CONCLUSIONS: The study demonstrated both the technical feasibility and didactic benefits of performing minimally invasive surgery in body donors as part of live surgery events. This novel concept has the potential to enhance anatomical knowledge, providing insights into complex surgical procedures, and may serve to overcome yet unresolved ethical concerns related to live surgery events.
RESUMO
PURPOSE: This study was performed to assess the practical laparoscopic training in Gynecological Endoscopy Working Group (AGE) certified Training Centers (TC) and evaluate the possible implementation for a manual dexterity skills-training within the Minimal Invasive Surgery (MIC) certification process. MATERIAL AND METHODS: An online questionnaire was developed and the link provided for the heads of the AGE TC. The questionnaire comprised topics on TC organization, practical training performance and perspectives for future training and demographic data. RESULTS: Response rate was 78.9% (15/19) of AGE TC. Grasping for the basic and suturing exercises for the advanced curricula, respectively, are thought to be of highest value (each 1.0 ± 0, on a scale from 1 = very valuable to 6 = not at all valuable). Most valuable parameter in assessing training was thought to be pressure/tension with 1.80 ± 1.08 The most valuable training capacity was considered for box training under supervision (1.27 ± 0.59) and feed-back box training with direct evaluation of various surgical skills (1.40 ± 0.63). Supervised box training was also thought to have the most positive influence on surgical performance (1.33 ± 0.49). The majority of respondents (86.7%) were qualified with the highest MIC certification and additional 66.7% were sub-specialized Gynecological Oncologists. CONCLUSION: The AGE certified TC offer a structured curriculum with emphasis on practical training. The results of this questionnaire and the additional respondents comments on value and future perspectives/changes of practical training support the concept and the implementation of a skills-training to the AGE MIC concept.

Modern surgical strategies aim to reduce trauma by using functional imaging to improve surgical outcomes. This reviews considers and evaluates the importance of the fluorescent dye indocyanine green (ICG) to visualize lymph nodes, lymphatic pathways and vessels and tissue borders in an interdisciplinary setting. The work is based on a selective search of the literature in PubMed, Scopus, and Google Scholar and the authors' own clinical experience. Because of its simple, radiation-free and uncomplicated application, ICG has become an important clinical indicator in recent years. In oncologic surgery ICG is used extensively to identify sentinel lymph nodes with promising results. In some studies, the detection rates with ICG have been better than the rates obtained with established procedures. When ICG is used for visualization and the quantification of tissue perfusion, it can lead to fewer cases of anastomotic insufficiency or transplant necrosis. The use of ICG for the imaging of organ borders, flap plasty borders and postoperative vascularization has also been scientifically evaluated. Combining the easily applied ICG dye with technical options for intraoperative and interventional visualization has the potential to create new functional imaging procedures which, in future, could expand or even replace existing established surgical techniques, particularly the techniques used for sentinel lymph node and anastomosis imaging.
RESUMO
Clusterin (CLU) is expressed in tissues and body fluids and is altered in some pathologies. In endometriosis, a noninvasive test is still lacking, thus, we analyzed CLU in mucus samples of patients. Additionally, we investigated localization of CLU and the putative CLU receptors (apolipoprotein E receptor 2 [ApoER2], megalin, very low-density lipoprotein receptor [VLDLR], and transforming growth factor ß receptor type I and II [TßR1/TßR2]). In mucus samples, CLU levels are modestly, but not significantly, higher in cases with endometriosis compared to cases without endometriosis, however, CLU levels are significantly (P = .02) reduced in patients with endometriosis receiving contraception compared to cases with endometriosis without contraception. Analysis of CLU and CLU receptors showed CLU mainly in the uterine epithelial cells in the majority of glands, but also in endothelial cells. Similarly, ApoER2 and TßR1 could also be found preferentially in the endometrial glands. Whereas ApoER2 staining was strong in the vessels, TßR1 was modestly expressed in vessels and muscle cells. In contrast, staining of VLDLR and TßR2 was modest in the glands but stronger in vessels and muscle cells. Megalin staining was faint in the glands. A similar pattern for these proteins could be observed in adenomyosis. We demonstrate for the first time high concentrations of CLU in mucus samples and significantly reduced CLU levels in cases with endometriosis receiving contraception compared to cases with endometriosis without contraception. Furthermore, we identified uterine epithelial and endothelial cells as the main source of CLU and found different preferential CLU receptor complexes on glands, vessels, and smooth muscle cells.

BACKGROUND: The purpose of this study was to evaluate serum HE4 as a biomarker to detect recurrent disease during follow-up of patients with endometrial adenocarcinoma (EAC). METHODS: We performed a retrospective analysis of 98 EAC patients treated at Innsbruck Medical University, between 1999 and 2009. Twenty-six patients developed recurrent disease. Median follow-up was 5 years. Serum HE4 and CA125 levels were analyzed using the ARCHITECT assay (Abbott, Wiesbaden, Germany) pre-operatively (baseline), post-operative (interval) and after histological confirmation of recurrent disease or when patients returned for clinical review with no evidence of recurrent disease (recurrence/final)). Receiver operator curves (ROC), Spearman rank correlation coefficient, chi-squared and Mann-Whitney tests were used for statistical analysis. RESULTS: HE4 levels decreased after initial treatment (p = 0.001) and increased again at recurrence (p = 0.002). HE4 was elevated (>70 pmol/L) in 21 of 26 (81%) and CA125 was elevated (>35 U/ml) in 12 of 26 (46%) patients at recurrence. In endometrioid histology (n = 69) serum HE4 measured during follow up (Area under the curve (AUC) = 0.87, 95%CI 0.79-0.95) was a better indicator of recurrence than CA125 (AUC = 0.67, 95%CI 0.52-0.83). A HE4 level of 70 pmol/L was associated with a sensitivity of 84%, a specificity of 74% and a negative predictive value of 93% when assessing for recurrent endometrioid EAC. CONCLUSION: This is a preliminary description of HE4 serum levels measured during routine follow up of EAC patients. Serum HE4 measured during clinical follow-up may identify recurrent disease particularly in patients with endometrioid histology. Further prospective validation of HE4 is warranted.

OBJECTIVE: The objective of this study was to evaluate the safety and efficacy of SprayShield™ Adhesion Barrier in preventing and/or reducing postoperative adhesion during gynecological surgery. DESIGN: This was a prospective, controlled, blinded, and randomized study. Patient blinding was performed intraoperatively. Subjects were randomly assigned to the SprayShield™ or the control group in a 2:1 ratio. SETTING: The study was conducted at the Clinic of Gynaecology and Obstetrics, at the University Hospital for Gynecology in Germany. PATIENTS: Fifteen patients participated in this study; nine patients were assigned to the SprayShield™ and six patients to the control group. INTERVENTIONS: During first operation (FLL) in the SprayShield™ group, the agent was applied to all myomectomy suture lines. Patients in the control group did not receive any anti-adhesion treatment, only good surgical practice. A second-look laparoscopy (SLL) was performed 8-12 weeks after myomectomy to evaluate adhesion formation. MAIN OUTCOME MEASURES: Main outcome measures were incidence, severity, and extent of uterine adhesions. RESULTS: No significant differences were found between the two study groups. CONCLUSIONS: SprayShield™ is easy to use. No serious adverse event related to SprayShield™ was observed. Efficacy data are inconclusive regarding the performance of SprayShield™. Further studies are needed to better understand this performance.

The present survey was conducted among gynaecological surgeons from several European countries to assess the actual knowledge and practice related to post-surgical adhesions and measures for reduction. From September 1, 2012 to February 6, 2013, gynaecological surgeons were invited to answer an 18-item online questionnaire accessible through the ESGE website. This questionnaire contained eight questions on care settings and surgical practice and ten questions on adhesion formation and adhesion reduction. Four hundred fourteen surgeons participated; 70.8 % agreed that adhesions are a source of major morbidity. About half of them declared that adhesions represented an important part of their daily medical and surgical work. About two thirds informed their patients about the risk of adhesion. Most cited causes of adhesions were abdominal infections and extensive tissue trauma, and endometriosis and myomectomy surgery. Fewer surgeons expected adhesion formation after laparoscopy (18.9 %) than after laparotomy (40.8 %); 60 % knew the surgical techniques recommended to reduce adhesions; only 44.3 % used adhesion-reduction agents on a regular basis. This survey gives a broad picture of adhesion awareness amongst European gynaecological surgeons, mainly from Germany and the UK. The participants had a good knowledge of factors causing adhesions. Knowledge of surgical techniques recommended and use of anti-adhesion agents developed to reduce adhesions need to be improved.
RESUMO
OBJECTIVE: HE4 has emerged as a promising biomarker in gynaecological oncology. The purpose of this study was to evaluate serum HE4 as a biomarker for high-risk phenotypes in a population-based endometrial cancer cohort. METHODS: Peri-operative serum HE4 and CA125 were measured in 373 patients identified from the prospective Australian National Endometrial Cancer Study (ANECS). HE4 and CA125 were quantified on the ARCHITECT instrument in a clinically accredited laboratory. Receiver operator curves (ROC), Spearman rank correlation coefficient, and chi-squared and Mann-Whitney tests were used for statistical analysis. Survival analysis was performed using Kaplan-Meier and Cox multivariate regression analyses. RESULTS: Median CA125 and HE4 levels were higher in stage III and IV tumours (p<0.001) and in tumours with outer-half myometrial invasion (p<0.001). ROC analysis demonstrated that HE4 (area under the curve (AUC)=0.76) was a better predictor of outer-half myometrial invasion than CA125 (AUC=0.65), particularly in patients with low-grade endometrioid tumours (AUC 0.77 vs 0.64 for CA125). Cox multivariate analysis demonstrated that elevated HE4 was an independent predictor of recurrence-free survival (HR=2.40, 95% CI 1.19-4.83, p=0.014) after adjusting for stage and grade of disease, particularly in the endometrioid subtype (HR=2.86, 95% CI 1.25-6.51, p=0.012). CONCLUSION: These findings demonstrate the utility of serum HE4 as a prognostic biomarker in endometrial cancer in a large, population-based study. In particular they highlight the utility of HE4 for pre-operative risk stratification to identify high-risk patients within low-grade endometrioid endometrial cancer patients who might benefit from lymphadenectomy.

BACKGROUND: We analysed the prevalence of the most common hereditary thrombophilia (hTP) - factor V Leiden (FVL) mutation, prothrombin 20210 G>A substitution (PT) - and the 677 C>T replacement in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene in Caucasian patients with a history of two and more consecutive recurrent miscarriages (RMs) as compared to healthy controls with an identical ethnic background and at least one live birth. METHODS: A multicenter analysis of three hTP was performed in 641 RM patients identically screened at specialized university centres. RESULTS: The study groups consisted of 240 patients with 2 (1) and 401 patients with >2 miscarriages (2) and were compared with 157 controls. There was no significant difference in the prevalence of the hTP between RM patients and controls nor within the two study groups. Subgroup analysis showed that the homozygous MTHFR polymorphism was significantly more prevalent in the study group 2 as compared to study group 1 (13.9 versus 7.9%, P = 0.02). CONCLUSION: In Caucasians, maternal FVL or PT mutations do not seem to contribute to the pathophysiology of RM, irrespective of the number of miscarriages. However, the role of the homozygous MTHFR polymorphism merits further investigation.

OBJECTIVE: Abdominopelvic infiltrative disease may require aggressive surgical procedures. This study reports on our experience with distal ureterectomy, ureteroureterostomy, and extravesical ureteroneocystostomy as part of radical surgery for infiltrating gynecologic disease. PATIENTS AND METHODS: Twenty-one women required surgery to the distal ureter at the Queensland Centre for Gynecological Cancer, Australia, from January 2006 to September 2012. Details of the patient's history, operation record, inpatient notes, and follow-up data were obtained through chart review. RESULTS: Patients' median age was 57.8 ± 14.7 years (range, 30-80 years). Seventeen patients had gynecologic cancer. Mean operating time was 3.9 ± 0.9 hours (range, 2.5-5.5 hours). Restoration of continuity was achieved through extravesical ureteroneocystostomy and ureteroureterostomy in 18 and 3 patients, respectively. Boari flap was used in 3 patients, and psoas hitch was the technique chosen in 11 patients. Urinary tract infection was the most common clinical adverse event. Albeit clinically irrelevant, 38% of the patients showed structural renal tract changes postoperatively. CONCLUSIONS: To achieve maximal surgical radicalness, resection of the distal ureter with subsequent ureteroureterostomy or extravesical ureteroneocystostomy is feasible and safe. Radical surgery to the urinary tract should be considered as a legitimate part of a gynecologic oncologist's surgical armamentarium to increase a patient's probability of survival and its positive effect on kidney function.

OBJECTIVE: Evaluating the presence of possible malignant disease in women with ovarian masses relies on medical imaging and serum marker findings. This study considers the role of serum Human Epididymal Protein 4 (HE4) antigen in combination with other serum markers to more effectively estimate the risk of malignancy in patients with isolated pelvic masses. METHODS: We used prospectively collected biospecimens held by the Australian Ovarian Cancer Study (AOCS). Serum samples of patients with FIGO stage 1 epithelial ovarian cancer or with a benign condition were analysed for levels of circulating HE4 antigen, CA 125, and CEA, and test results were used to predict the presence of malignancy and to differentiate benign from malignant pelvic masses. RESULTS: HE4 levels were significantly elevated amongst postmenopausal women and amongst patients with malignancy compared to premenopausal women and those with benign disease (p<0.001 for both). The combination of CA125 and age, achieved an area under the ROC curve of 0.677 (95% CI: 0.584 to 0.770, p=0.778), whilst HE4+CA125+CEA in combination with patient's age showed significantly higher AUC of 0.797 (95% CI: 0.721 to 0.874, p=0.0052). By adjusting the ROMA cut-off values the percentage of correctly classified premenopausal patients into low and high risk groups increased from 36.99% to 69.86%. CONCLUSIONS: In patients with isolated pelvic masses, the combination of HE4, CA 125 and age with or without CEA provides higher diagnostic value compared to CA125 and age alone. It may therefore be considered for continuous evaluation in patients with adnexal masses.

OBJECTIVE: To evaluate the effects of different suture materials and techniques on soft tissue in relation to defined tensions and time points. MATERIALS AND METHODS: Two bovine intestine samples, 4 × 4 cm size and ~3 mm thickness, were adapted with interrupted and continuous techniques using three types of suture materials: Vicryl (polyglactin 910), PDS II (polydioxanone), and V-Loc 180 (knotless, barbed polyglyconate). Four stitches or loops 9 mm apart with three knots, and 10 mm end length were performed by one gynecologist. Forces were applied from 6 newtons (N) to 14 N continuously. Outcome measures included breakage of tissue, tearing of thread, and shortening of the end length of thread. They were evaluated immediately and then at first, third, and fifth minute. RESULTS: Tissue breakage using No. 3/0 suture materials appears in the applied force from 10 N. polydioxanone causes more tissue tearing than polyglactin 910. The least to withstand tension is knotless polyglyconate. Interrupted stitches hold the sutured sites better than continuous stitches in all groups of threads. Shortening of the knotless polyglyconate end length by half took place with 6 N force. CONCLUSION: Simulating reparation of colpotomy, the ex vivo study supports that polyglactin 910 appears better in holding soft tissue than polydioxanone and knotless polyglyconate.

OBJECTIVES: Obesity is associated with the incidence of endometrial cancer. At present it is unclear whether it is also associated with cancer recurrence. This analysis evaluated the consequences of weight changes after diagnosis of endometrial cancer during the follow-up. METHODS: Records of patients with endometrial cancer (n = 705) were reviewed for body weight after the diagnosis of cancer during the follow-up and related to recurrence-free survival. RESULTS: About two-thirds of all endometrial patients gained more or less weight after the diagnosis of endometrial cancer. Patients with moderate weight gain (≤ 1 kg/m(2)) 6 months after the diagnosis had the best prognosis, followed by patients with greater weight gain (>1 kg/m(2)) and those with moderate weight loss (≤ 1 kg/m(2)). The fact that weight loss was associated with poor prognosis also persisted when the analysis was restricted to recurrences which occurred more than 18 months later. CONCLUSIONS: Weight loss after the diagnosis and treatment of cancer may be an adverse prognostic factor. Although it was impossible to distinguish between intentional and non-intentional weight loss, these results argue against weight loss for risk reduction in patients with confirmed endometrial cancer. However, it may be reasonable regarding the risk reduction of non-cancer related morbidity and mortality. Detailed, prospective randomised trials are warranted.

BACKGROUND: Adhesions lead to considerable patient morbidity and are a mounting burden on surgeons and the health care system alike. Although adhesion formation is the most frequent complication in abdominal and pelvic surgery, many surgeons are still not aware of the extent of the problem. To provide the best care for their patients, surgeons should consistently inform themselves of anti-adhesion strategies and include these methods in their daily routine. METHODS: Searches were conducted in PubMed and The Cochrane Library to identify relevant literature. FINDINGS: Various complications are associated with adhesion formation, including small bowel obstruction, infertility and chronic pelvic pain. Increasingly, an understanding of adhesion formation as a complex process influenced by many different factors has led to various conceivable anti-adhesion strategies. At present, a number of different anti-adhesion agents are available. Although some agents have proved effective in reducing adhesion formation in randomised controlled trials, none of them can completely prevent adhesion formation. CONCLUSION: To fulfil our duty to provide best possible care for our patients, it is now time to regard adhesions as the most common complication in surgery. Further research is needed to fully understand adhesion formation and to develop new strategies for adhesion prevention. Large clinical efficacy trials of anti-adhesion agents will make it easier for surgeons to decide which agent to use in daily routine.

OBJECTIVES: This study was done to analyze the frequency of use of acupuncture and other complementary and alternative medicine (CAM) methods during labor and to investigate the different characteristics of women being treated with or without acupuncture and CAM methods, as well as try to analyze birth-related outcome measures. STUDY DESIGN: Data were analyzed from 409,413 deliveries, registered between 2001 and 2008 by the agency for quality assurance in Hesse (the Hessian Perinatal Registry [HEPE] survey), which made up more than 95% of all deliveries in this German state during the given time period. RESULTS: Interest in the use of CAM seems to have decreased within the given time period. On average, acupuncture was used in 3.7% (15,345/409,295) of all deliveries and other CAM methods in 4.8% (19,507/409,295). The most important determinant for the use of one or both methods was the type of hospital. It was also found that German women with higher job qualifications were more likely to receive CAM treatment during delivery. Interestingly, application of CAM methods was associated with a higher use of analgesics during labor. The risk status of the pregnancy or the delivery was of minor importance. CONCLUSIONS: This analysis shows that the determinants of CAM use are similar to those in the field of oncology. In order to assess the efficacy of acupuncture or other CAM methods in the field of obstetrics, it seems necessary to extend the HEPE survey to cover these areas.

AIM: The impact of postsurgical intra-abdominal adhesions, which represent a considerable burden for patients and health services, is often underestimated. Various factors influence adhesion formation, including the surgical approach. This study aimed to further understand the condition by investigating surgeons' perceptions of adhesion formation, particularly differences after laparoscopic and open surgery, and by performing a selective literature review. MATERIALS AND METHODS: South Asian surgeons attending endoscopy symposia in India and in Germany completed Likert-scale-based questionnaires on awareness of adhesion formation and associated consequences in gynecology. MEDLINE and PubMed were searched for articles published in 2000-2010 comparing laparoscopy and laparotomy in relation to adhesion formation. The results of the questionnaire study were then considered in view of findings from this review. RESULTS: In total, 43.1% (97/225) of questionnaires were completed. Respondents considered that laparoscopy caused fewer adhesions than laparotomy for all gynecological procedures. Although they believed their knowledge of adhesion formation was satisfactory, they widely underestimated the risk, giving estimated rates of 12.5% after laparoscopy and 36.3% after laparotomy. Twenty-eight studies were identified in the review. Most concluded that laparoscopy was less likely to cause adhesions than laparotomy but further statistical analysis was precluded because so many different definitions and classifications of adhesions had been used. CONCLUSIONS: The risk of adhesion formation was widely underestimated in the study group. Both the questionnaire study and the review concluded that laparoscopy results in less adhesion than laparotomy but further statistical comparison necessitates the development of standard definitions and classifications of adhesions.

PURPOSE: Ovarian small cell carcinoma of the hypercalcaemic type is a very rare and highly aggressive malignant disease, mainly affecting young women. Due to the rarity of this tumour entity, prospective randomised trials are unlikely to be conducted, and the only retrospective analysis based on a large case series is from 1994. Since diagnostic and treatment modalities may have changed, we initiated this analysis. METHODS: The aim of our study was to review and analyse cases published since 1975 to validate former findings and to gather more information about therapy options, diagnostic and prognostic factors. A systematic literature search of the PubMed/Medline database was performed assessing all articles until September 2010. All retrieved articles were evaluated and cross-checked for references on the topic. In total, 135 cases were included, selected from 62 case reports and smaller case studies. RESULTS: Small cell carcinoma mostly affects women with a mean age of 23.4 years. They present with unspecific symptoms like abdominal pain or palpable mass, sometimes accompanied by an elevated calcium or CA-125 serum concentration. The tumour appears nearly almost unilaterally, mostly affecting the right ovary. Tumour stage is a clearly prognostic factor. Adjuvant chemotherapy consisting of etoposide, cisplatinum/carboplatinum or vinca alkaloids has shown improved survival, whereas radiotherapy has not. CONCLUSIONS: In spite of limitations this analysis provides new insights especially with respect to therapeutic aspects. This review underlines the importance of case reports in rare tumour entities in order to answer open questions.
