RESUMEN

RESEARCH QUESTION: Is ovarian stimulation with levonorgestrel intrauterine system (LNG-IUS) in situ and co-treatment with letrozole safe and effective in patients undergoing fertility-sparing combined treatment for atypical endometrial hyperplasia (AEH) or early endometrial cancer limited to the endometrium? DESIGN: Retrospective case-control study recruiting women who had undergone fertility-sparing 'combined' treatment and ovarian stimulation with letrozole and LNG-IUS in situ. The 'three steps' hysteroscopic technique was used. Once complete response was achieved, the ovaries were stimulated, and mature oocytes cryopreserved. The LNG-IUS was removed, and embryos transferred. A comparative analysis was conducted between the two control groups of the initial outcomes of ART (number of oocytes and MII oocytes retrieved): healthy infertile women undergoing ovarian stimulation for IVF/ICSI (control group A); and patients diagnosed with breast cancer who underwent ovarian stimulation with letrozole (control group B). RESULTS: Of the 75 patients analysed, 15 underwent oocyte cryopreservation after achieving a complete response to fertility-sparing treatment (study group); 30 patients in control group A and B, respectively. No statistically significant differences were observed in retrieved oocytes and mature oocytes between the study and control groups. In the nine patients who underwent embryo transfer, clinical pregnancy (55.6%), cumulative live birth (44.4%) and miscarriage (20%) rates were reported. In three patients with AEH, recurrence occurred (12%) at 3, 6 and 16 months after removing the LNG-IUS to attempt embryo transfer, respectively. CONCLUSION: Fertility-sparing hysteroscopic combined treatment and subsequent ovarian stimulation with letrozole and LNG-IUS in situ could be suggested to women with AEH or early endometrial cancer who ask for future fertility preservation.

RESUMEN

Uterine Tumors Resembling Ovarian Sex Cord Tumors (UTROSCTs) are rare uterine mesenchymal neoplasms with uncertain biological potential. These tumors, which affect both premenopausal and postmenopausal women, usually have a benign clinical course. Nevertheless, local recurrences and distant metastases have been described. By analyzing 511 cases retrieved from individual reports and cases series, we provide here the most comprehensive overview of UTROSCT cases available in the literature, supplemented by two new cases of UTROSCTs. Case 1 was an asymptomatic 31-year-old woman who underwent a laparoscopic resection of a presumed leiomyoma. Case 2 was a 58-year-old postmenopausal woman with abnormal vaginal bleeding who underwent an outpatient hysteroscopic biopsy of a suspicious endometrial area. In both cases, immunohistochemical positivity for Calretinin and Inhibin was noted, typical for a sex cord differentiation. In both cases, total laparoscopic hysterectomy with bilateral salpingo-oophorectomy was performed. In light of the available literature, no pathognomonic clinical or imaging finding can be attributed to UTROSCT. Patients usually present with abnormal uterine bleeding or pelvic discomfort, but 20% of them are asymptomatic. In most cases, a simple hysterectomy appears to be the appropriate treatment, but for women who wish to become pregnant, uterus-preserving approaches should be discussed after excluding risk factors. Age, tumor size, lymphovascular space invasion, nuclear atypia, and cervical involvement are not reliable prognostic factors in UTROSCT. The current research suggests that aggressive cases (with extrauterine spread or recurrence) can be identified based on a distinct genetic and immunohistochemical phenotype. For instance, UTROSCTs characterized by GREB1::NCOA1-3 fusions and PD-L1 molecule expression appear to be predisposed to more aggressive behaviors and recurrence, with GREB1::NCOA2 being the most common gene fusion in recurrent tumors. Hence, redefining the criteria for UTROSCTs may allow a better selection of women suitable for fertility-sparing treatments or requiring more aggressive treatments in the future.

RESUMEN

RESEARCH QUESTION: To explore normal uterine contractile function across the menstrual cycle using a novel quantitative ultrasound method. DESIGN: This multicentre prospective observational study took place in three European centres from 2014 to 2022. Uterine contraction frequency (contractions/minute), amplitude, direction (cervix-to-fundus, C2F; fundus-to-cervix; F2C), velocity and coordination were investigated. Features were extracted from transvaginal ultrasound recordings (TVUS) using speckle tracking. Premenopausal women ≥18 years of age, with normal, natural menstrual cycles were included. A normal cycle was defined as: regular (duration 28 ± 2 days), no dysmenorrhoea, no menometrorrhagia. Four-minute TVUS were performed during the menstrual phase, mid-follicular, late follicular phase, early luteal phase and/or late luteal phase. Of the 96 recordings available from 64 women, 70 were suitable for inclusion in the analysis. RESULTS: Contraction frequency (for the posterior wall) and velocity (for the anterior uterine wall in the F2C direction) were highest in the late follicular phase and lowest in the menstrual and late luteal phases (1.61 versus 1.31 and 1.35 contractions/min, P < 0.001 and 0.81 versus 0.67 and 0.62 mm/s, P < 0.001, respectively). No significant difference was found for contraction amplitude. Contraction coordination (simultaneous contraction of the anterior and posterior walls in the same direction) was least coordinated in the mid-follicular phase (P = 0.002). CONCLUSIONS: This is the first study to objectively measure uterine contraction features in healthy women during the natural menstrual cycle on TVUS. Likewise, it introduces contraction coordination as a specific feature of uterine peristalsis. Differences in uterine contractility across the menstrual cycle are confirmed, with highest activity seen in the late follicular phase, and lowest in the late luteal phase.

RESUMEN

BACKGROUND: Cesarean scar ectopic pregnancy is a type of ectopic pregnancy in which the fertilized egg is implanted in the muscle or fibrous tissue of the scar after a previous cesarean delivery. The condition can be catastrophic if not managed on time and can lead to significant morbidity and mortality. Several approaches have been studied for the management of cesarean scar ectopic pregnancy in women who opted for termination of pregnancy with no consensus on the best treatment modality reached so far. OBJECTIVE: This study aimed to compare the success rate of hysteroscopic resection vs ultrasound-guided dilation and evacuation for the treatment of cesarean scar ectopic pregnancy. STUDY DESIGN: This was a parallel group, nonblinded, randomized clinical trial conducted at a single center in Italy. Women with singleton gestations at <8 weeks and 6 days of gestation were included in the study. Inclusion criteria were women with a cesarean scar ectopic pregnancy with positive embryonic heart activity who opted for termination of pregnancy. Patients were randomized 1:1 to receive either hysteroscopic resection (ie, intervention group) or ultrasound-guided dilation and evacuation (ie, control group). Both groups received 50 mg/m2 of methotrexate intramuscularly at the time of randomization (day 1) and another dose at day 3. A third dose of methotrexate was planned in case of persistence of positive fetal heart activity at day 5. Participants received either ultrasound-guided dilation and evacuation or hysteroscopic resection from 1 to 5 days after the last dose of methotrexate. Hysteroscopic resection was performed under spinal anesthesia using a 15 Fr bipolar mini-resectoscope. Dilation and evacuation were performed by vacuum aspiration with a Karman cannula, followed by sharp curettage, if necessary, under ultrasound guidance. The primary outcome was the success rate of the treatment protocol, defined as no further treatment required until the complete resolution of the cesarean scar ectopic pregnancy. Resolution of the cesarean scar ectopic pregnancy was evaluated based on decline of beta-hCG and the absence of residual gestational material in the endometrial cavity. Treatment failure was defined as the necessity for further treatment required until the complete resolution of the cesarean scar ectopic pregnancy. A sample size calculation indicated that 54 participants were required to test the hypothesis RESULTS: A total of 54 women were enrolled and randomized. Number of previous cesarean deliveries ranged from 1 to 3. Overall, 10 women received a third dose of methotrexate with 7 of 27 (25.9%) participants in the hysteroscopic resection group and 3 of 27 (11.1%) in the dilation and evacuation group. The success rate was 100% (27/27) in the hysteroscopic resection group and 81.5% (22/27) in the dilation and evacuation group (relative risk, 1.22; 95% confidence interval, 1.01-1.48). Additional procedures were required in 5 cases of the control group, namely 3 hysterectomies, 1 laparotomic uterine segmental resection, and 1 hysteroscopic resection. The length of stay in the hospital was 9.0±2.9 days in the intervention group and 10.0±3.5 days in the control group (mean difference, -1.00 days; 95% confidence interval, -2.71 to 0.71). No cases of admission to intensive care unit or maternal death were reported. CONCLUSION: Hysteroscopic resection was associated with an increased success rate in the treatment of cesarean scar ectopic pregnancy when compared with ultrasound-guided dilation and evacuation.

RESUMEN

STUDY OBJECTIVE: To demonstrate our hysteroscopic technique using the mini-resectoscope for the treatment of complete uterine septum with or without cervical anomalies. DESIGN: A step-by-step video demonstration of the technique with the use of an educational video. SETTINGS: We present 3 patients diagnosed as having complete uterine septum (U2b according to the ESHRE/ESGE classification) with or without cervical anomalies (C0, normal cervix; C1, septate cervix; C2, double "normal" cervix"), 2 of them with a longitudinal vaginal septum (V1). The first case is a 33-year-old woman with history of primary infertility diagnosed as having a complete uterine septum with normal cervix (class U2bC0V0 according to the ESHRE/ESGE classification). Case 2 is a 34-year-old woman with infertility and abnormal uterine bleeding, diagnosed as having complete uterine and cervical septum and a partial nonobstructive vaginal septum (class U2bC1V1). Case 3 is a 28-year-old woman with infertility and dyspareunia, diagnosed as having a complete uterine septum, double "normal" cervix, and nonobstructive longitudinal vaginal septum (class U2bC2V1) Still 3. The procedures were performed in a tertiary care university hospital. INTERVENTION: The 3 procedures were performed in the operative room using a 15 Fr continuous flow mini-resectoscope and bipolar energy with the patient under general anesthesia Still 1 and Still 2. No complications were encountered in any of the 3 cases. After all procedures, a gel based on hyaluronic acid was applied to minimize postoperative adhesion formation. Patients were discharged home the same day of the procedure after a short period of observation. CONCLUSION: Hysteroscopic treatment of patients with uterine septa associated or not with cervical anomalies using miniaturized instruments is a feasible and effective option for the management of patients with these complex müllerian anomalies.

RESUMEN

OBJECTIVE: To describe an effective in-office hysteroscopic strategy to restore fertility of patients with severe Asherman's syndrome. DESIGN: A step-by-step video demonstration of the technique with an emphasis on the key portions of the procedure. A detailed narrated description of the steps is provided. SETTING: Tertiary care University Hospital. INTERVENTIONS: Three patients were managed by hysteroscopy performed in the office setting without anesthesia. Case 1 is a 34-year-old woman with obstetrical history of first-trimester incomplete abortion treated with Dilation and Curettage (D&C), followed by a tubal ectopic pregnancy treated with laparoscopic partial salpingectomy and a subsequent pregnancy on the tubal stump treated with uterine artery embolization. Case 2 is a 40-year-old woman with history of tubal ectopic pregnancy treated with salpingectomy, a surgical first-trimester voluntary termination of pregnancy with D&C and a full term vaginal delivery complicated with retained products of conception that were removed with D&C. Case 3 is a 35-year-old woman with two previous first-trimester spontaneous miscarriages both treated with D&C. Case 1 and 3 were treated using miniaturized mechanical instruments only; in case 2, miniaturized mechanical instruments and the 15 Fr bipolar mini-resectoscope were used. Preoperative 2D and 3D ultrasound were used to predict the complexity of the cases and to guide the surgeon during the procedure. Intrauterine lysis of adhesions was concluded when both tubal ostia were visualized, and the uterine cavity was determined to have adequate shape and volume. At the end of the procedures, hyaluronic acid-based gel was applied to prevent new intrauterine adhesion formation. Two weeks after the initial procedure, a second look diagnostic hysteroscopy was performed. Only one patient (#1) needed additional lysis of adhesions; in this case, at the end of the procedure, a Word catheter was inserted as a barrier method for the prevention of adhesion formation. Eight weeks later, the word catheter was removed, and additional lysis of adhesions was performed. All the surgical procedures were performed without complication, and a healthy endometrium was observed at the second look hysteroscopy, in all the three patients. All 3 patients conceived after the procedure. Pregnancy was achieved after one IVF cycle with the transfer of one frozen embryo in case 1 and spontaneously in cases 2 and 3. Patient 1 was delivered by elective caesarean section due to placenta previa, while the other two patients had normal vaginal deliveries. Patient 1 had Retained Products of Conception requiring hysteroscopic removal using a 27 Fr Resectoscope. CONCLUSION: When using innovative miniaturized instruments and adequate surgical technique, hysteroscopic lysis of adhesions is a feasible and effective in-office strategy to restore fertility in patients with severe Asherman's syndrome. The use of 2D and 3D ultrasound played an important role in the preoperative workup of the patient with Asherman's syndrome.

RESUMEN

STUDY OBJECTIVE: To describe the diagnostic workup and laparoscopic management of a noncommunicating left uterine rudimentary horn (class U4aC0V0 European Society of Human Reproduction and Embryology/European Society of Gastrointestinal Endoscopy Classification) with communicating endometriotic bladder nodule. DESIGN: Step-by-step description of the surgical treatment. PATIENT: A 33-year-old woman with unicornuate uterus and a left-side noncommunicating rudimentary horn affected by primary infertility, mild dysmenorrhea (visual analog scale score 6), severe catamenial dysuria (visual analog scale score 10), and catamenial hematuria. SETTING: Noncommunicating rudimentary horns are rare Müllerian anomalies present in 20% to 25% of women with a unicornuate uterus. It is associated with severe dysmenorrhea, pelvic pain, subfertility, and poor obstetric outcomes and usually presents with cyclic pelvic pain that starts early after the menarche. Endometriotic bladder nodules are present in 1% to 2% of patients with endometriosis. In the literature, there are no reported cases of noncommunicating rudimentary horn with communicating endometriotic bladder nodules. Surgical excision of the rudimentary horn is the treatment of choice. In our case, the 2-dimensional/3-dimensional ultrasound revealed a right unicornuate uterus with a left noncommunicating rudimentary horn with hematometra. The uterine fundus presented «gamma sign¼ vascularization. In addition, a bladder endometriotic nodule (16 × 15 mm) communicating with hematometra was displayed. Magnetic resonance imaging demonstrated no additional malformations. Diagnostic hysteroscopy revealed a single cervix without vaginal malformation and small right uterine cavity with single tubal ostium. At laparoscopy, using hysteroscopic transillumination, a clear plane of dissection was identified between the rudimentary horn and the uterus confirming the presence of a noncommunicating horn. Evaluation of the abdominal cavity showed bilateral normal adnexa with normal ovaries. Chromopertubation showed a patent right Fallopian tube and obstructed left tube. INTERVENTIONS: A left salpingectomy using bipolar and the ultrasonic energy was performed. The utero-ovarian ligament was transected, and the left ovary was preserved. The left ovary was suspended at the pelvic wall, the retroperitoneum was opened, the ureter was identified, and the left uterine artery was temporary occluded. The left round ligament was transected and the left paravesical space was developed. With a lateromedial approach, we opened the vesicouterine septum to dissect the bladder from the rudimentary horn. The endometriotic bladder nodule was gently detached from the uterine horn with a lateromedial approach. The left uterine artery was coagulated and dissected at level of the cervix. A solution of vasopressin was injected between the uterine horn and the uterus. Resection of the rudimentary horn was performed. The peritoneum was closed. The temporary occlusion of the uterine artery was removed. The specimen was placed in a bag and removed using an extracorporeal tissue extraction technique. CONCLUSION: The late clinical presentation of our patient with only mild dysmenorrhea could be explained by the drainage of the hematometra from the noncommunicating horn into the endometriotic bladder nodule. The bladder symptoms in patients with Müllerian anomalies should be carefully investigated. The laparoscopic removal of rudimentary horn with mobilization of communicating bladder nodule when present is a safe and feasible method to improve symptomatology.

RESUMEN

OBJECTIVE: Hysteroscopy is considered the gold standard technique for the diagnosis and management of intrauterine pathology allowing to "see and treat" patients in 1 session if desired [1-3]. Pain and the inability to enter the uterine cavity are the most common limitations of hysteroscopy, especially when performed in an office setting [4-7]. Cervical stenosis is a common hysteroscopic finding frequently encountered in postmenopausal women, especially in patients with a history of cervical procedures such as cone biopsy [8]. It represents a challenge even for the most expert hysteroscopist. Overcoming the stenosis of the external cervical os is technically more demanding than facing the obliteration of the internal os. The aim of this video article is to illustrate the use of simple techniques that allow the hysteroscopist to safely identify the location of the external cervical os and to overcome the difficulties in entering the uterine cavity during in-office hysteroscopy in patients with severe cervical stenosis including those with complete obliteration of the external cervical os. These techniques are easy to adopt and can be used in different clinical situations in which the hysteroscopic evaluation of the uterine cavity is needed in women with severe cervical stenosis. DESIGN: A series of videos of challenging cases with severe cervical stenosis with complete obliteration of the external cervical os are presented that demonstrate maneuvers to properly identify and enter the cervical canal, unfolding key aspects of the procedure. Tips and tricks to facilitate the adoption of these useful maneuvers into clinical practice are highlighted. SETTING: In-office diagnostic hysteroscopy was performed using a 5-mm rigid continuous flow operative hysteroscope. Patients were placed in a dorsal lithotomy position. The vaginoscopy "no touch" technique was used [9]. No anesthesia or sedation was administered to any of the patients. Normal saline was used as distention media. INTERVENTIONS: Taking advantage of the magnification provided by the hysteroscope, the location of the external cervical os was determined. In cases in which the external cervical os was not clearly recognized, the cervix was gently probed with the use of the uterine palpator, grasper, or scissors (Fig. 1). Recognition of the landmarks of the cervical canal provides reassurance of the adequate identification of the external cervical os and facilitates the use of the correct plane of dissection that leads into the uterine cavity (Fig. 2). Additional maneuvers that are useful to navigate the endocervical canal to overcome stenosis of the internal cervical os are also illustrated. CONCLUSION: The combination of a delicate technique and operator experience aids in overcoming the challenge of cervical stenosis in an office setting. Adopting the presented tips and tricks to enter the uterine cavity in the presence of severe cervical stenosis will reduce the rate of failed hysteroscopic procedures, decreasing the need to take patients to the operating room and the use of general anesthesia.

RESUMEN

Polycystic ovary syndrome (PCOS) is a complex and heterogeneous endocrine disease. The hypothesis that alterations in the microbiome are involved in the genesis of PCOS has been postulated. Aim of this review is to summarize the available literature data about the relationship between microbiome and PCOS. A search on PubMed and Medline databases was performed from inception to November 20Most of evidence has focused on the connection of intestinal bacteria with sex hormones and insulin-resistance: while in the first case, a relationship with hyperandrogenism has been described, although it is still unclear, in the second one, chronic low-grade inflammation by activating the immune system, with increased production of proinflammatory cytokines which interfere with insulin receptor function, causing IR (Insulin Resistance)/hyperinsulinemia has been described, as well as the role of gastrointestinal hormones like Ghrelin and peptide YY (PYY), bile acids, interleukin-22 and Bacteroides vulgatus have been highlighted. The lower genital tract microbiome would be affected by changes in PCOS patients too. The therapeutic opportunities include probiotic, prebiotics and synbiotics, as well as fecal microbiota transplantation and the use of IL-22, to date only in animal models, as a possible future drug. Current evidence has shown the involvement of the gut microbiome in PCOS, seen how humanized mice receiving a fecal transplant from women with PCOS develop ovarian dysfunction, immune changes and insulin resistance and how it is capable of disrupting the secondary bile acid biosynthesis. A future therapeutic approach for PCOS may involve the human administration of IL-22 and bile acid glycodeoxycholic acid.

RESUMEN

Surgical innovations in hysteroscopic surgery have radically changed the way of treating intrauterine pathologies, throughout the advent of the 'see-and-treat' philosophy, which transferred the advantages of inpatient surgery to the office setting. However, in-office operative hysteroscopy was mainly limited to minor pathology as a supplement to its diagnosis, whereas commonly larger abnormalities were left to be treated in the operating room. Nowadays, pre-surgical assessment of uterine pathology is based on modern ultrasound evaluation and the evolving role of in-office hysteroscopy as a well-planned treatment modality for larger lesions and more complex procedures. Office operative hysteroscopy has been accepted as a feasible, cost-effective, practical way to treat almost any intrauterine disease. Despite the growing role of other imaging tools in the proper evaluation of benign uterine diseases, especially extended beyond to direct hysteroscopic visualization, diagnostic hysteroscopy remains a valuable tool of direct endometrial sampling and may be used as the first line in the diagnosis of endometrial cancer and hyperplasia. Our aim is to describe the most recent innovations and future perspectives in the field of outpatient operative hysteroscopy: mini-resectoscopes, intrauterine morcellators, tissue retrieval systems, diode laser, new miniaturized mechanical instruments, endometrial ablation devices and portable and entry-level hysteroscopes.

RESUMEN

OBJECTIVE: To investigate the diagnostic accuracy of endometrial biopsy performed with hysteroscopic direct visualization using the "grasp technique" for the detection of endometrial carcinoma (EC) histology type and tumor grade. METHODS: A cross-sectional study including the clinical and pathology records of patients with confirmed EC who underwent definitive surgery at University of Naples was performed. The preoperative diagnosis of endometrial tumor type and grade obtained using the hysteroscopy grasp technique was correlated with the final pathology specimens. Those results were compared to the diagnostic accuracy of the biopsies collected in a cohort of patients who underwent preoperative diagnostic hysteroscopy followed by blind endometrial biopsy using the Novak curette with subsequent surgical definitive treatment at University of Pisa. Statistical analysis was based on frequency data and diagnostic agreement of the pathology results. RESULTS: A total of 129 patients were included in the final analysis. An agreement rate of 104/106 (98.1%) for endometrioid type and 15/23 (65.2%) for non-endometrioid type was obtained between preoperative hysteroscopic grasp endometrial biopsy specimens and the final pathology with a coefficient k for G1, G2 and G3 tumors of 0.928, 0.925 and 0.974, respectively. When compared to 121 patients undergoing preoperative blind Novak endometrial biopsy, the hysteroscopic grasp technique was superior in agreement rates for tumor histotype [diagnostic accuracy (0.922 vs 0.890); K value (0.705 vs 0.642)] and grade when in presence of endometrioid type EC (K Cohen 0.354 for G1, 0.263 for G2 and 0.488 for G3). CONCLUSIONS: Preoperative hysteroscopic guided "grasp" endometrial biopsy provides a more accurate diagnosis of EC histology type and tumor grade when in presence of endometrioid type tumor compared to blind endometrial biopsy obtained using the Novak curette.

RESUMEN

OBJECTIVE: To evaluate the long-term reproductive outcomes in patients with dysmorphic uterus treated by hysteroscopic metroplasty with miniaturized instruments. DESIGN: Retrospective multicenter cohort study. SETTING: Tertiary care university hospitals. PATIENTS: The study was conducted on 214 women with a dysmorphic uterus (T-shaped, infantilis, or other type of dysmorphic uterus according to the European Society of Human Reproduction and Embryology and the European Society for Gynaecological Endoscopy classification system) with history of primary unexplained infertility (group 1) or repeated (>2) early miscarriages (group 2). Dysmorphic uteri were diagnosed by office hysteroscopy and 3-dimensional transvaginal ultrasound (3D-TVS). INTERVENTIONS: All patients underwent in office hysteroscopic metroplasty using a continuous-flow hysteroscope with a 5 Fr operating channel introduced into the uterine cavity using the vaginoscopic approach. Longitudinal incisions were performed on the fibromuscular constriction rings in the isthmic area and in some cases on the other uterine walls with a 5 Fr bipolar electrode or scissors. At the end of the procedure, an antiadhesive gel was applied into the uterine cavity to minimize adhesion formation. Postsurgical assessment of the uterine cavity was carried out through office hysteroscopy and 3D-TVS. All patients were followed for at least 24 months. MEASUREMENTS AND MAIN RESULTS: The metroplasty was completed in all cases, resulting in a significant increase of uterine cavity volume (100%) and optimization of uterine morphology in 211 of 214 women (98.6%). After 60 months, the overall clinical pregnancy rate was 72.9% (n = 156/214), and the live birth rate was 80.1% (n = 125/156). Specifically, 74 of 156 women (47.4%) conceived spontaneously (with a median time to pregnancy of 5.5 months), of whom 32.4% had previously failed 1 or more attempts at in vitro fertilization/intracytoplasmic sperm injection. CONCLUSION: Our long-term follow-up data demonstrate that the hysteroscopic correction of dysmorphic uteri may result in a high live birth rate in women suffering from unexplained infertility or repeated miscarriages.

RESUMEN

The aim of this study is to summarize evidence on the effectiveness of virtual reality simulators for experienced and novice surgeons in improving their hysteroscopic skills. Three types of hysteroscopic simulators were evaluated: Hyst Sim VR, Virtual Reality Uterine Resectoscopic Simulator, Essure Sim TM. Virtual reality simulators have been assessed to be highly relevant to reality and all surgeons attained significant improvements between their pre-test and post-test phases, independent of their previous level of experience, demonstrating more improvement among novices than experts. Available evidence supports the effectiveness of virtual simulators in increasing the diagnostic and surgical skills of gynaecologists, independent from their starting level of expertise.

RESUMEN

Ovarian cancer is considered the leading cause of death among gynecologic neoplasias. Breast metastases from primary ovarian cancer have been reported in only 0.03-0.6% of all breast cancers. A 38-year-old female, multipara, affected by advanced ovarian cancer and undergone a total abdominal hysterectomy with bilateral salpingo-oophorectomy, omentectomy, and pelvic peritonectomy two years earlier, was discovered to have a breast metastasis. She underwent a quadrantectomy (QSI) with an open biopsy of nodularity attached to the pectoral muscle fascia: on definitive histological characterization the breast lesions showed a high-grade invasive carcinoma, with papillary serum differentiation, and the immunohistochemistry study of breast lesion showed positivity for cytokeratin 7 and an extensive positivity for Wilm's tumor (WT)-1 and paired box 8 (PAX8). These aspects are indicative of mammary metastasis from carcinoma of ovarian origin. Despite their rarity, metastases to breast from ovarian cancer should be considered possible because their recognition and differentiation compared to primary tumors are crucial for prognosis. Future clinical studies on MOCB should be performed to discover new specific markers for a more accurate histopathological diagnosis and to establish the real need of surgical treatment.

RESUMEN

STUDY OBJECTIVES: To describe and demonstrate a technique for laparoscopic removal of a perforating intrauterine device (IUD) during pregnancy, and to provide tips to facilitate safe laparoscopic surgery during pregnancy. DESIGN: Video presentation of the technique for laparoscopic removal of a perforating IUD in a pregnant woman. SETTING: Department of Neuroscience, Reproductive Sciences, and Dentistry, University of Naples Federico II, Naples, Italy. INTERVENTION: A 30-year-old woman, gravida 3, para 2, with a copper T IUD (Nova T 380; Bayer, Leverkusen, Germany) perforating the left adnexa presented to the emergency room complaining of left lower quadrant pain. The patient had the IUD inserted by her gynecologist 3 months before the onset of the symptoms. Ultrasound revealed a 6-week intrauterine pregnancy with the presence of fetal cardiac activity along with the IUD perforating the left adnexa. The patient returned at 11 weeks of gestation complaining of worsening abdominal pain and excruciating left lower quadrant pain. She was scheduled for laparoscopic excision of the perforating IUD [1-3]. Considering her pregnancy, laparoscopy under regional anesthesia was performed in the minimal Trendelenburg position at 12 degrees, through open laparoscopic access [4]. Intra-abdominal pressure of 8 mmHg and ultrasound energy to cut and coagulate, avoiding monopolar/bipolar energy owing to the presence of a copper IUD, were used. The IUD and tube were extracted in an endobag through umbilical access, under a 5-mm, 0-degree telescope in left lateral access [5]. The procedure was carried out uneventfully, and the IUD was removed. Fetal viability was confirmed after the procedure. At the time of this report, the patient was in the 23rd week of gestation, and the pregnancy was progressing without any problems. CONCLUSION: Laparoscopic removal of perforated IUD during pregnancy under regional anesthesia is a feasible and safe option that should be considered when needed.

RESUMEN

STUDY OBJECTIVE: To evaluate safety and effectiveness of the combination of hysteroscopic endometrial focal resection with levonorgestrel-releasing intrauterine device (LNG-IUD) for International Federation of Gynecology and Obstetrics stage IA G1 early endometrial cancer (EEC) and atypical endometrial hyperplasia (AEH) in young women to preserve their fertility. DESIGN: Retrospective case series (Canadian Task Force classification II-3). SETTING: University Federico II, Naples, Italy. PATIENTS: The medical records of 69 consecutive patients treated from 2007 to 2017 with diagnosis of EEC (n = 14) or AEH (n = 55) meeting inclusion criteria were reviewed. INTERVENTIONS: Patients with focal EEC were treated by hysteroscopic resection of the lesion according to Mazzon's technique; patients with AEH were treated by superficial endometrial resection, preserving the basal layer of the endometrium. An LNG-IUD was inserted in all patients after surgery. Patients were followed for 24 months with serial hysteroscopic biopsies. MEASUREMENTS AND MAIN RESULTS: Rates of response, live birth, and recurrence were assessed. Of the 14 patients with EEC, 11 (78.6%) achieved a complete response, 2 (18.2%) of whom had subsequent relapse, 1 (7.1%) showed partial response, whereas 2 (14.3%) were nonresponders (1 stable disease and 1 progression). Of the 55 patients with AEH, 51 (92.7%) achieved a complete response, 2 (3.9%) of whom had subsequent relapse, 3 (5.5%) showed partial response, whereas only 1 (1.8%) was nonresponder with stable disease. Among 25 patients who had removed the LNG-IUD, 10 (40%) gave birth after natural conception in the last 12 months of follow-up. CONCLUSION: The combination of hysteroscopic resection with an LNG-IUD as fertility-sparing treatment of EEC and AEH showed similar response and live birth rates compared with those reported in literature for progestins alone, but with considerably lower relapse rate. We advocate the use of this combined approach as an alternative fertility-sparing option in patients with ECC and AEH.

RESUMEN

STUDY OBJECTIVE: To demonstrate our technique for surgical hysteroscopy performed with a standard-size resectoscope or miniresectoscope in 3 cases of isthmocele. DESIGN: Step-by-step demonstration of the technique using slides, pictures, and video (educative video) (Canadian Task Force classification III). SETTING: Isthmocele is a characteristic semidiverticular anomaly of the anterior isthmic wall of the uterus, located at the site of a previous cesarean delivery scar. The etiopathogenesis of isthmocele remains poorly understood, although several hypotheses have been proposed. Factors that may possibly play a role in niche development include a very low incision through cervical tissue, inadequate suturing technique during closure of the uterine scar, surgical interventions that increase adhesion formation, and patient-related factors that impair wound healing or increase inflammation or adhesion formation. The treatment of isthmocele focuses on relieving symptoms (i.e., postmenstrual spotting, suprapubic pelvic pain, dysmenorrhea, dyspareunia, and infertility), and, consequently, asymptomatic cases should not be treated. Various surgical approaches have been described to treat isthmocele-related symptoms, including hysteroscopy, laparoscopy, vaginal, robotic, and combined techniques. INTERVENTION: Our local Institutional Review Board approved the study protocol. The procedures were performed in operative room using a 26 Fr and 16 Fr continuous-flow resectoscope under general anesthesia. The surgical technique involves resection of the fibrotic tissue of the lower margin and then the upper margin of the pouch using a cutting loop, until the underlying muscular tissue is reached, followed by resection of the inflamed and necrotic tissue of the base of the pouch. Similar surgical maneuvers are performed on the contralateral side (right anterolateral wall) for complete ablation of the isthmic region (inverted ablation). CONCLUSION: According to the most recent literature, hysteroscopic hystmoplasty appears to be a safe and effective treatment option in cases of isthmocele with a niche at least 2 mm deep and a residual myometrial thickness of at least 3 mm to improve postmenstrual bleeding. When residual myometrial thickness is <3 mm, the hysteroscopic approach is not recommended, mainly because of the risk of bladder injury. In these symptomatic cases, laparoscopic or vaginal repair may be considered.

RESUMEN

STUDY OBJECTIVE: To describe safety, tolerability, and effectiveness results through a minimum 2-year follow-up of patients who underwent permanent sterilization with the Essure insert. DESIGN: A retrospective multicenter study (Canadian Task Force classification II2). SETTING: Seven general hospitals and 4 clinical teaching centers in Italy. PATIENTS: A total of 1968 women, mean age 39.5 years (range, 23-48 years) who underwent office hysteroscopic sterilization using the Essure insert between April 1, 2003, and December 30, 2014. INTERVENTION: The women underwent office hysteroscopic bilateral Essure insert placement, with satisfactory device location and tube occlusion based on hysterosalpingography or hysterosalpingo-contrast sonography (HyCoSy). MEASUREMENTS AND MAIN RESULTS: Placement rate, successful bilateral tubal occlusion, perioperative adverse events, early postoperative (during the first 3 months of follow-up), and late complications were evaluated. Satisfactory insertion was accomplished in 97.2% of women and, in 4, perforation and 1 expulsion were detected during hysterosalpingography. Three unintended pregnancies occurred before the 3-month confirmation test. Two pregnancies were reported among women relying on the Essure inserts. Postprocedure pain was minimal and brief; in 9 women, pelvic pain became intractable, necessitating removal of the devices via laparoscopy. On telephone interviews, overall satisfaction was rated as "very satisfied" by the majority of women (97.6%), and no long-term adverse events were reported. CONCLUSION: The findings from this extended Italian survey further support the effectiveness, tolerability, and satisfaction of Essure hysteroscopic sterilization when motivated women are selected and well informed of the potential risks of the device. Moreover, the results do not demonstrate an increased incidence of complications and pregnancies associated with long-term Essure use. Patients with a known hypersensitivity to nickel may be less suitable candidates for the Essure insert.
