Role of single port robotic surgery in gynecology.

Robot-assisted Single-Site Laparoscopy (R-LSS) is a rapidly evolving minimally invasive technique. Although it is a very recent technology, the use of R-LSS have been increasingly report in gynecology, for both benign and malignant indications. This review aims to summarize the evolution of this innovative technique and to examine its feasibility and safety for gynecological surgical procedures. We evaluated studies dealing about R-LSS in gynecological surgery. We performed a comprehensive literature research on PubMed and the Cochrane Library in February 2024. Based on the study reviewed, R-LSS seems to be a feasible and effective alternative to other mini-invasive approach in gynecological surgery. R-LSS combine the advantages of robotics surgery with the aesthetic result of a single incision. Compare to Single-Site Laparoscopy, it restore triangulation of the instrument and improve visualization and ergonomic. R-LSS seems to be related to favourable intra-e post-operative outcomes. Although, further studies would be necessary allow us to draw any final conclusion.

Sentinel-lymph-node mapping with indocyanine green in robotic-assisted laparoscopic surgery for early endometrial cancer: a retrospective analysis.

BACKGROUND: The therapeutic value of lymphadenectomy in early stage endometrial cancer (EC) is still debated. Sentinel-lymph-node identified with indocyanine green (ICG) can replace lymphadenectomy in the staging of endometrial cancer minimizing the potential morbidity of a complete lymphadenectomy. The aim of this study was to analyze our initial experience using indocyanine green for sentinel-lymph-node mapping in a minimally robotic-assisted laparoscopic approach with Da Vinci XI near-infrared (NIR) fluorescence imaging system. METHODS: A total of 23 patients who underwent robot-assisted laparoscopic surgery with the Da Vinci Xi Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) with NIR imaging and ICG fluorescence detection for early stage EC were retrospectively analyzed. RESULTS: Sentinel-lymph-node mapping was achieved in 18 patients for a detection rate of 78.26%, bilateral pelvic detection was possible in 14 patients (60.9%) and no sentinel-lymph-node mapping was noted in 4 patients (17.4%). We compared 11 patients (Group 1) at intermediate and high- risk of recurrence who underwent sentinel-lymph- node mapping and pelvic lymphadenectomy and 12 patients (Group 2) at low risk of recurrence who underwent only sentinel-lymph-node mapping. A statistically significant difference was found for the average operation time and for the hospital stays. CONCLUSIONS: The high detection rate, absence of intraoperative or postoperative complications, the short time required for mapping and removal of the sentinel-lymph-nodes and the short duration of the hospital stay, support performing sentinel-lymph-node in all women with early endometrial cancer.

Inositol and In Vitro Fertilization with Embryo Transfer.

Recently, studies on inositol supplementation during in vitro fertilization program (IVF) have gained particular importance due to the effect of this molecule on reducing insulin resistance improving ovarian function, oocyte quality, and embryo and pregnancy rates and reducing gonadotropin amount during stimulation. Inositol and its isoforms, especially myoinositol (MYO), are often used as prestimulation therapy in infertile patients undergoing IVF cycle. Inositol supplementation started three months before ovarian stimulation, resulting in significant improvements in hormonal responses, reducing the amount of FSH necessary for optimal follicle development and serum levels of 17beta-estradiol measured the day of hCG injection. As shown by growing number of trials, MYO supplementation improves oocyte quality by reducing the number of degenerated and immature oocytes, in this way increasing the quality of embryos produced. Inositol can also improve the quality of sperm parameters in those patients affected by oligoasthenoteratozoospermia.

Robotic single site staging in endometrial cancer: A multi-institution study.

OBJECTIVE: To evaluate the feasibility and the safety of robotic single site hysterectomy (RSSH) plus or less pelvic lymphadenectomy in FIGO stage I-II endometrial cancer. MATERIALS AND METHODS: We prospectively collected patient demographics, operative times, complications, pathologic results, and length of stay on all patients who underwent RSSH plus or less pelvic lymphadenectomy for clinical FIGO stage I or occult stage II endometrial carcinoma. RESULTS: From January 2012 to February 2015, 125 patients were included in our study. The median age of the patients was 59 years (range, 35-84 years) and the median body mass index was 27 kg/m(2) (range, 19-52 kg/m(2)). One patient was converted to vaginal surgery due to problems of hypercapnia. The median docking time, console time, and total operative time was 11 min (range, 4-40 min), 80 min (range, 20-240 min) and 122 min (range, 35-282 min), respectively. The median blood loss was 50 ml (range, 10-250 ml). No laparoscopic/laparotomic conversion was registered. Twenty one patients underwent pelvic lymphadenectomy (16.8%) and the median pelvic lymph nodes was 13 (range, 3-32). The median time to discharge was 2 days (range, 1-3 days). No intra-operative complications occurred, while we observed 10 (8%) early post-operative complications. CONCLUSION: RSSH plus or less pelvic lymphadenectomy is technically feasible, safe and reproducible and could be the treatment of choice for patients affected by FIGO stage I-II endometrial cancer. However, randomized controlled trials are needed to confirm these results.

[Robotic-assisted laparoscopy for deep infiltrating endometriosis: the Register of the Society of European Robotic Gynaecological Surgery]. / Place de la robotique dans l'endométriose pelvienne profonde : à propos du registre de la SERGS.

OBJECTIVES: To assess the interest of robotic-assisted laparoscopy in the context of deep infiltrating endometriosis and to investigate perioperative results. PATIENTS AND METHODS: From November 2008 to April 2012, 164 women with stage IV endometriosis who underwent robotic-assisted laparoscopy (DA VINCI Intuitive Surgical System(®)) were included by eight international participating clinical centers. Patients were divided in 4 groups according to the localization of the nodule(s): rectum (n=88), bladder (n=23), ureter and uterosacral ligaments (n=115) et hysterectomy (n=28). We evaluated the procedures performed, the duration of intervention, the complications, the recurrence and the impact on fertility. RESULTS: In the rectum group, there was a laparotomy conversion, 2 sutured rectal injuries and a red cells blood transfusion. In the bladder group, there was a vesicovaginal hematoma and a prolongated intermittent self-catheterization. In the ureter and uterosacral ligaments group, there was 2 ureteral fistulas and there was no complication in the hysterectomy group. DISCUSSION AND CONCLUSION: This study is the largest series published in the literature on robotic-assisted laparoscopy for deep infiltrating endometriosis. The interest of robotic-assisted laparoscopy in deep infiltrating endometriosis seems to be promising while no increase in surgical time, blood loss, and intra- and postoperative complications were observed.

Hysterectomy for benign uterine pathology: comparison between robotic assisted laparoscopy, classic laparoscopy and laparotomy.

OBJECTIVE: Hysterectomy is one of the most important surgeries in gynecology and requires a lot of care and skill. In this study we attempt to make a comparison between laparoscopic hysterectomy, robotic assisted hysterectomy and abdominal hysterectomy for treatment of uterine pathology. MATERIALS AND METHODS: We conducted a study comparing 29 patients who were treated by robotic assisted laparoscopic hysterectomy in Cisanello Hospital, Pisa, Italy, 30 patients who were treated by laparoscopy in General Surgery Clinic, Craiova and 30 patients who were treated by abdominal hysterectomy in General Surgery Clinic, Craiova. RESULTS: Comparing the surgeries, it was noticed that the operative time of a robotic assisted interventions is the largest, 183.9 minutes. Even if the duration was greater, the time needed to perform vaginal suture was lower, 17.75 minutes to 22.79 minutes by classic laparoscopic approach. In terms of blood loss we concluded that intraoperative blood loss was lowest during a robotic surgery, 199.3 ml versus 285 ml in the laparoscopic group and 417 ml in the laparotomic group. CONCLUSIONS: Robotic assisted laparoscopic hysterectomy is a feasible method that can be used very successfully to treat patients diagnosed with benign uterine pathology.

Robotic single-site hysterectomy: feasibility, learning curve and surgical outcome.

BACKGROUND: The field of laparoscopy has undergone several changes to improve the morbidity and cosmesis of laparoscopic surgery. The robotic single-site surgery is the inevitable hybridization of robotic technology with laparoendoscopic single-site surgery. METHODS: Perioperative information of 12 robotic single-site hysterectomies (R-SSH) were collected to evaluate the surgical feasibility and the possible influence of the body mass index (BMI) and the uterine weight on operative times. RESULTS: The mean operative time was 85 ± 33 min (range, 355 to 149 min), the mean docking time was 9 ± 3 min, and the mean console time was 76 ± 33 min. The mean blood loss was 80 ± 18 mL, and the median weight of resected uteri was 220 ± 45 g. No serious postoperative complications occurred. The CUSUM learning curve was observed to consist of two different phases: phase 1 (the initial 6 cases) and phase 2 (the last 6 cases) with significant reduction in operative and console time observed between the two phases. For BMI, no correlation was found with operative times, console times, and docking times, and no correlation was found between uterine weight and operative time. CONCLUSIONS: This series, identifying two different phases of the learning curve and suggesting that the initial learning phase for the procedure can be achieved after six cases, confirms the feasibility and safety of a robotic approach for single-site hysterectomy. However, the limits of this study mainly rely on the limited casuistic and short follow-up, although the preliminary results appear promising. Larger series and prospective studies comparing R-SSH hysterectomy with standard robotic multiport hysterectomy are necessary to define properly the role of this innovative surgical technique.

Steroid hormones and BDNF.

Brain-derived neurotrophic factor (BDNF) is a neurotrophin abundantly expressed in several areas of the central nervous system (CNS) and is known to induce a lasting potentiation of synaptic efficacy, to enhance specific learning and memory processes. BDNF is one of the key molecules modulating brain plasticity and it affects cognitive deficit associated with aging and neurodegenerative disease. Several studies have shown an altered BDNF production and secretion in a variety of neurodegenerative diseases like Alzheimer's and Parkinson's diseases but also in mood disorders like depression, eating disorders and schizophrenia. Plasma BDNF is also a biomarker of impaired memory and general cognitive function in aging women. Gonadal steroids are involved in the regulation of several CNS processes, specifically mood, affective and cognitive functions during fertile life and reproductive aging. These observations lead many scientists to investigate a putative co-regulation between BDNF and gonadal and/or adrenal steroids and their relationship with gender difference in the incidence of mental diseases. This overview aims to summarize the current knowledge on the correlation between BDNF expression/function and both gonadal (progesterone, estrogens, and testosterone) and adrenal hormones (mainly cortisol and dehydroepiandrosterone (DHEA)) with relevance in clinical application.

Endocrine and clinical effects of myo-inositol administration in polycystic ovary syndrome. A randomized study.

OBJECTIVE: To evaluate the effects the administration of myo-inositol (MYO) on hormonal parameters in a group of polycystic ovary syndrome (PCOS) patients. DESIGN: Controlled clinical study. SETTING: PCOS patients in a clinical research environment. PATIENTS: 50 overweight PCOS patients were enrolled after informed consent. INTERVENTIONS: All patients underwent hormonal evaluations and an oral glucose tolerance test (OGTT) before and after 12 weeks of therapy (Group A (n»10): MYO 2 g plus folic acid 200 mg every day; Group B (n»10): folic acid 200 mg every day). Ultrasound examinations and Ferriman-Gallwey score were also performed. MAIN OUTCOME MEASURES: Plasma LH, FSH, PRL, E2, 17OHP, A, T, glucose, insulin, C peptide concentrations, BMI, HOMA index and glucose-to-insulin ratio. RESULTS: After 12 weeks of MYO administration plasma LH, PRL, T, insulin levels and LH/FSH resulted significantly reduced. Insulin sensitivity, expressed as glucose-to-insulin ratio and HOMA index resulted significantly improved after 12 weeks of treatment. Menstrual cyclicity was restored in all amenorrheic and oligomenorrheic subjects. No changes occurred in the patients treated with folic acid. CONCLUSIONS: MYO administration improves reproductive axis functioning in PCOS patients reducing the hyperinsulinemic state that affects LH secretion.

Fertility and endocrine outcome after robot-assisted laparoscopic myomectomy (RALM).

INTRODUCTION: Laparoscopic myomectomy has recently gained wide acceptance but this procedure remains technically highly demanding and concerns have been raised about the increased blood loss and an higher risk of postoperative uterine rupture of the pregnant uterus. OBJECTIVE: The aim of the present study is to evaluate the fertility and endocrine outcome in women underwent robot-assisted laparoscopic myomectomy (RALM). METHODS: Data from 48 RALM performed in our department between the years 2007 and 2011 have been collected. Conception rate, abortion rate, incidence of feto-maternal morbidity or severe pregnancy and labor-related complications were reported; FSH and AMH levels and ultrasound valuation of AFC has been made before and 6 months after operation. Number of cesarean sections and vaginal deliveries were described. RESULTS: The average age of the patients was 35 years and median Body Mass Index was 23 kg/m(2) (range 18-35 kg/m(2)). Seven women (13%) became pregnant after RALM with eight pregnancies. One pregnancy is actually on going; there were six deliveries with caesarian section and one spontaneous delivery. No spontaneous abortions. No uterine ruptures occurred. No significant modification of ovarian function was found after myomectomy. CONCLUSION: RALM seems to have a favorable impact on the reproductive outcome of young patients with no impact on the ovarian function.

Polycystic ovary syndrome: brain-derived neurotrophic factor (BDNF) plasma and follicular fluid levels.

Polycystic ovary syndrome is one of the most common endocrine disorders in women of reproductive age. Features of PCOS are hyperandrogenism, chronic anovulation and polycystic ovaries on ultrasonography. Follicle development is a complex and carefully orchestrated phenomenon, involving gonadotropins and a rapidly expanding list of other intraovarian regulators, such as brain-derived neurotrophic factor (BDNF). The aim of this study is to evaluate BDNF in plasma and in follicular fluid in women affected by PCOS and in normal menstruating women. In PCOS patients the BDNF levels in plasma and in follicular fluid are higher than values obtained in healthy controls. Therefore we can hypothsize that high levels of luteinizing hormone, probably increase the secretion of BDNF in PCOS patients.

Best methods for identification and treatment of PCOS.

The polycystic ovarian syndrome (PCOS) includes a wide spectrum of clinical symptoms and signs. Three different diagnostic classifications have been proposed to define this disease. The first one, published in 1990, known as the "NIH criteria" requires the simultaneous presence of hyperandrogenism and menstrual dysfunction in order to diagnose PCOS. Later on, in 2003, an expert panel met in Rotterdam and added to the previous criteria the presence of polycystic ovarian morphology detected by transvaginal ultrasonography. The later classification broadened the spectrum of PCOS and also included women with oligomenorrhea and PCO without hyperandrogenism or hyperandrogenism and PCO without menstrual dysfunction. Finally, the Androgen Excess Society, published in 2006 new diagnostic criteria which required the presence of clinical or biochemical hyperandrogenism, with either PCO or menstrual dysfunction to diagnose PCOS. This review focuses on the diagnostic techniques and methods of treatment for PCOS patients. Special attention is given to the role of insulin resistance and the potential utility of insulin sensitizers in management of the syndrome. The benefit and utmost importance of lifestyle modification for the long-term health of these women is stressed as well. It is hoped that some clarity in this regard will allow more women to not only be diagnosed and managed properly for their presenting symptoms (hirsutism, irregular menses, etc.), but also to be educated and managed for the continuing health risk of insulin resistance throughout their lives.

Daily variation of brain-derived neurotrophic factor and cortisol in women with normal menstrual cycles, undergoing oral contraception and in postmenopause.

BACKGROUND: Plasma brain-derived neurotrophic factor (BDNF) levels are associated with the hormonal status of women. Moreover, the suprachiasmatic nucleus appears to be implicated in the modulation of BDNF central levels. We aimed to investigate whether BDNF circadian rhythms exist in women and if there is a relationship with cortisol circadian rhythmicity. Moreover, we aimed to establish whether the hormonal status influences BDNF diurnal variations. METHODS: A total of 30 women were studied: 10 fertile ovulatory women, 10 women undergoing oral contraceptive (OC) therapy and 10 post-menopausal women. Basal BDNF and estradiol levels were assayed in blood samples collected after overnight fasting at regular intervals (08:00, 12:00, 16:00, 20:00, 24:00). BDNF and cortisol levels were measured in samples collected during the follicular and luteal phases in ovulatory women and once a month in OC and post-menopausal women. RESULTS: Luteal BDNF levels were significantly higher than follicular levels in fertile women (P < 0.001). In OC women, BDNF levels were similar to the follicular BDNF levels, whereas in post-menopausal women, they were significantly lower (P < 0.001). BDNF showed a diurnal rhythm in the follicular phase and in women undergoing OC, although the diurnal rhythm was blunted in the luteal phase. In post-menopausal women, BDNF and cortisol levels significantly decreased during the day. CONCLUSIONS: BDNF has a diurnal variation in women that is somewhat analogous to cortisol variation; however, the amplitude of the variation in BDNF levels appears to be influenced by ovarian function. Interactions between BDNF, the hypothalamus-pituitary-adrenal axis and sex steroids might play a critical role in the human homeostasis and adaptation.

Progestogens and brain: an update.

Each synthetic progestins has its own specific activities on different tissues, which can vary significantly between progestins of different classes and even within the same class. Indeed, different progestins may support or oppose the effects of estrogen depending on the tissue, thereby supporting the concept that the clinical selection of progestins for HRT is critical in determining potential positive or detrimental effects. These actions might be particularly relevant in the central nervous system (CNS) where progesterone (P) has pivotal roles besides reproduction and sexual behavior, going from neuropsychological effects to neuroprotective functions. Growing evidence supports the idea that synthetic progestins differ significantly in their brain effects, and clinical studies indicate that these differences also occur in women. Molecular and cellular characterization of the signaling properties of synthetic progestins in brain cells is therefore required and is hoped will lead to a better clinical utilization of the available compounds, as well as to new concepts in the engineering of new molecules. The aim of the present paper is to briefly review and compare neuroendocrine effects of progestogens with special reference to P metabolism into neuroactive steroids and the opioids system.

Brain derived neurotrophic factor circulating levels in patients undergoing IVF.

PURPOSE: The aim of the study was to measure circulating BDNF levels, a neurotrophin recently identified in the ovary, in parallel with estradiol, to verify if assessing this factor could add any predictive value to the outcome of in vitro fertilization. METHODS: Blood sampling for BDNF and estradiol was performed in 23 subjects undergoing IVF on day 1 (D1), day 8 (D8), day of HCG administration (DHCG) and day of oocyte retrieval.(DOR). RESULTS: There was a positive correlation between BDNF and estradiol throughout the stimulation cycle in all subjects. In both pregnant and nonpregnant patients, the values of BDNF grew significantly only between D8 and DHCG and remained constant until DOR. Between-group comparisons showed no statistically significant differences in both BDNF and estradiol values throughout the IVF cycle. CONCLUSION: Although BDNF plasma concentrations are not seemingly predictive of IVF outcome, this neurotrophin is highly correlated to estradiol levels and seems to be an important factor especially in the periovulatory period.

Impact of Italian legislation regulating assisted reproduction techniques on ICSI outcomes in severe male factor infertility: a multicentric survey.

BACKGROUND: In 2004, a law regulating assisted reproduction techniques (ART) was passed in Italy. The new rules allow for the formation and transfer of a maximum of three embryos at one time, whereas embryo selection and embryo storage are prohibited. The aim of this study is to evaluate the impact of these restrictions on ICSI outcome in couples affected by severe male factor infertility. METHODS: Thirteen Italian ART Units were involved in this study. Data were collected on ICSI cycles performed during 2 years before (control group) and 2 years after (study group) the enforcement of the law. Only cases of obstructive azoospermia (OA), non-obstructive azoospermia (NOA) and severe oligoastenoteratozoospermia (OAT) (sperm count

Vascular endothelial growth factor and its soluble receptor in ovarian pathology.

OBJECTIVE: The soluble form of the vascular endothelial growth factor (VEGF) receptor, s-VEGFR-1, may negatively regulate the action of VEGF. Our purpose was to better understand the regulation of angiogenetic processes in ovarian cysts. METHODS: Seventy-three women, 36 with serous cystoadenoma, 30 with ovarian endometriosis and seven with cystoadenocarcinoma, were enrolled. We calculated both VEGF and s-VEGFR-1 levels in cystic fluid and a VEGF activity index by means of the ratio VEGF/s-VEGFR-1. Student's t test was used for the statistical analysis. RESULTS: We found higher VEGF concentration in both endometriotic and malignant lesions than in serous cystoadenoma (p=0.03 and 0.001, respectively). Also s-VEGFR-1 concentration was higher in endometrioma than in serous cysts (p=0.005); however, there was no statistically significant difference between cystoadenoma and the malignant lesions (p=0.15). VEGF activity index in cystoadenoma, endometriotic and malignant lesions was 0.61, 0.27 and 0.50, respectively. CONCLUSIONS: VEGF certainly has an important role in both ovarian endometriosis and for cancer progression; however, the activity index may be better to investigate the real role of VEGF in the pathology we have considered.
