Assessing ovarian stimulation with letrozole and levonorgestrel intrauterine system after combined fertility-sparing approach for atypical endometrial lesions: a retrospective case-control study.

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.

Uterine cervical stenosis: from classification to advances in management. Overcoming the obstacles to access the uterine cavity.

BACKGROUND: To date hysteroscopy is the gold standard technique for the evaluation and management of intrauterine pathologies. The cervical canal represents the access route to the uterine cavity. The presence of cervical stenosis often makes entry into the uterine cavity difficult and occasionally impossible. Cervical stenosis has a multifactorial etiology. It is the result of adhesion processes that can lead to the narrowing or total obliteration of the cervical canal. PURPOSE: In this review, we summarize the scientific evidence about cervical stenosis, aiming to identify the best strategy to overcome this challenging condition. METHODS: The literature review followed the scale for the quality assessment of narrative review articles (SANRA). All articles describing the hysteroscopic management of cervical stenosis were considered eligible. Only original papers that reported data on the topic were included. RESULTS: Various strategies have been proposed to address cervical stenosis, including surgical and non-surgical methods. Medical treatments such as the preprocedural use of cervical-ripening agents or osmotic dilators have been explored. Surgical options include the use of cervical dilators and hysteroscopic treatments. CONCLUSIONS: Cervical stenosis can present challenges in achieving successful intrauterine procedures. Operative hysteroscopy has been shown to have the highest success rate, particularly in cases of severe cervical stenosis, and is currently considered the gold standard for managing this condition. Despite the availability of miniaturized instruments that have made the management of cervical stenosis more feasible, it remains a complex task, even for experienced hysteroscopists.

Uterine Tumors Resembling Ovarian Sex Cord Tumors (UTROSCTs): A Scoping Review of 511 Cases, Including 2 New Cases.

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.

Hysteroscopic resection vs ultrasound-guided dilation and evacuation for treatment of cesarean scar ectopic pregnancy: a randomized clinical trial.

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.

Step-by-Step Hysteroscopic Treatment of Complete Uterine Septum Associated or Not with Cervical Anomalies.

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.

Restoring Fertility of Patients with Severe Asherman's Syndrome in the Office Setting: A Step-by-Step Recipe for Success.

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.

Diode laser use in hysteroscopic surgery: current status and future perspectives.

Recent advances in surgical technology and innovative techniques have revolutionized surgical gynecology, including transcervical hysteroscopic procedures. Surgical lasers (Nd-Yag, Argon, diode, and CO2 lasers) have been promoted to remove a variety of gynecological pathologies. For hysteroscopic surgery, the diode laser represents the most versatile and feasible innovation, with simultaneous cut and coagulate action, providing improved hemostasis compared with CO2 laser. The newest diode laser devices exhibit increased power and a dual wavelength, to work precisely with reduced thermal dispersion and minimal damage to surrounding tissues. Their efficacy and safety have been validated both in the hospitals as well as in the office setting. Updated evidence reports that several hysteroscopic procedures, including endometrial polypectomies, myomectomies and metroplasties can be successfully performed with a diode laser. Therefore, this review aimed to give a deeper understanding of the role of laser energy in gynecology and subsequently in hysteroscopy in order to safely incorporate this technology into clinical practice.

Unicornuate Uterus with Noncommunicating Rudimentary Horn (Class U4aC0V0/ESHRE/ESGE Classification) and a Communicating Bladder Endometriotic Nodule.

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.

Ovarian Drilling: Back to the Future.

Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility. The complex metabolic dysregulation at the base of this syndrome often renders infertility management challenging. Many pharmacological strategies have been applied for the induction of ovulation with a non-negligible rate of severe complications such as ovarian hyperstimulation syndrome and multiple pregnancies. Ovarian drilling (OD) is currently being adopted as a second-line treatment, to be performed in case of medical therapy. Laparoscopic ovarian drilling (LOD), the contemporary version of ovarian wedge resection, is considered effective for gonadotropins in terms of live birth rates, but without the risks of iatrogenic complications in gonadotropin therapy. Its endocrinal effects are longer lasting and, after the accomplishment of this procedure, ovarian responsiveness to successive ovulation induction agents is enhanced. Traditional LOD, however, is burdened by the potential risks of iatrogenic adhesions and decreased ovarian reserve and, therefore, should only be considered in selected cases. To overcome these limits, novel tailored and mini-invasive approaches, which are still waiting for wide acceptance, have been introduced, although their role is still not well-clarified and none of them have provided enough evidence in terms of efficacy and safety.

Distension media delivery systems in hysteroscopy: past, present and future.

To examine the uterine cavity and/or to perform hysteroscopic surgery, one has to access the uterine cavity through the cervix, distend the cavity with a fluid (liquid or gas) to visualize it with a telescope and/or a camera system and use energy (mechanical or thermal) to affect and/or remove tissue. Distension of the uterine cavity then is an important component of hysteroscopy, and during the last century, numerous attempts have been made to achieve an undistorted and unobstructed panoramic view of the uterine cavity. In order to achieve this goal, the uterine cavity has been distended with fluids using a variety of techniques, including gravity-assisted systems, pressure cuffed systems, and electronic pumps. Excessive fluid intravasation during hysteroscopy can lead to significant complications, and hence, automated fluid delivery systems have been developed recently to provide a safe and more efficient method of fluid delivery. This review aims to describe the evolution of distension media delivery systems chronologically from the 1900s to the present day.

The Invisible External Cervical Os. Tips and Tricks to Overcome this Challenge during In-Office Hysteroscopy.

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.

Innovations in hysteroscopic surgery: expanding the meaning of "in-office".

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.

Hysteroscopic endometrial biopsy: from indications to instrumentation and techniques. A call to action.

During the last twenty years, the diagnostic approach to endometrial pathology has radically evolved. For over a century, intrauterine blind biopsy techniques were considered the gold standard procedure for the histopathological diagnosis of intrauterine diseases. The advent of hysteroscopy, which made it possible to directly visualize the uterine cavity, and the subsequent miniaturization of the instruments allowing its use in the office setting without anesthesia are considered game-changers. To date, it is feasible to retrieve a targeted eye specimen of endometrial tissue with little or no discomfort for the patient in the office setting. To pursue this aim, several technological upgrades have improved the diagnostic accuracy of hysteroscopic endometrial biopsy. In this paper we provide an up-to-date review of the latest evidence regarding indications, instrumentations, and techniques for hysteroscopic endometrial biopsy, to help the operator in providing an adequate endometrial sampling for histopathological analysis.

Should endometrial biopsy under direct hysteroscopic visualization using the grasp technique become the new gold standard for the preoperative evaluation of the patient with endometrial cancer?

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.

Laparoscopic treatment of advanced interstitial pregnancy: key steps for a successful management.

OBJECTIVE: To describe a conservative laparoscopic treatment of an advanced case of interstitial pregnancy diagnosed in a woman at 14 weeks of gestational age. DESIGN: A video case report with demonstration of diagnostic workup and laparoscopic management of rare subtypes of ectopic pregnancy. SETTING: University tertiary care hospital. PATIENT(S): A 32-year-old nulliparous woman at 14 weeks of gestational age, presented with moderate abdominal pain. She reported a history of irregular periods; however, no risk factor for ectopic pregnancy was identified. The human chorionic gonadotropin level was 7,345 mIU/mL. Transvaginal ultrasound revealed an empty uterine cavity and a complex heterogeneous mass of 6 cm on the left cornual region. The myometrial thickness surrounding the gestational sac was 4 mm. INTERVENTION(S): There were several critical strategies for this laparoscopic approach. To reduce intraoperative bleeding, the peritoneum was opened, the ureters were identified, and bulldog clamps were used to temporarily reduce uterine vascularization. An intramyometrial injection of vasopressin was performed. After the first cornuostomy attempt, we had to perform a cornual resection to achieve complete removal of the ectopic mass. Multilayer uterine sutures and anatomical restoration to prevent adhesion were then accomplished. Institutional review board approval was not required for this case report as per our institution's policy; patient consent was obtained for publication of the case. MAIN OUTCOME MEASURE(S): Description of laparoscopic management of huge interstitial pregnancy. RESULT(S): The overall operation time was 55 minutes, and the estimated blood loss was 55 mL. A successfully conservative treatment was achieved with no short-term complications. Postoperative ultrasound showed a normal uterus, and complete regression of human chorionic gonadotropin level was achieved 2 weeks after surgery. CONCLUSION(S): Interstitial ectopic pregnancy presents a high risk of maternal mortality considering that the interstitial part of the tube, because of its thickness, has a great capacity to expand before rupture. Despite the dimension of the lesion, in our case, the tube was still intact and the patient was in a stable clinical condition. Although cornuostomy is a more conservative solution, in these cases, cornual resection should be preferred. Through the accomplishment of reproducible key steps, laparoscopic removal of interstitial pregnancy is a feasible method and can be proposed even for advanced cases of interstitial pregnancies.

Myomectomy in infertile women: More harm than good?

Adhesion formation following gynecological surgery remains a challenge. The adoption of minimally invasive surgical approaches, such as conventional or robotic-assisted laparoscopy combined with meticulous microsurgical principles and the application of adhesion-reducing substances, is able to reduce the risk of de novo adhesion formation but do not eliminate it entirely. Myomectomy is the most adhesiogenic surgical procedure and postoperative adhesions can have a significant impact on the ability to conceive. Therefore, when surgery is performed as infertility treatment, attention should be paid to whether the benefits outweigh the risks. Among several factors, the size and the location of fibroids are the most accountable factors in terms of adhesion development and post surgical infertility; therefore, the search for effective strategies against adhesion formation in this setting is of paramount importance. The purpose of this review is to evaluate the incidence and factors of adhesion formation and the best preventive measures current available.

A Bayesian Network Model for Supporting School Managers Decisions in the Pandemic Era.

Due to the dramatic health situation caused by the COVID-19 pandemic, in Italy the emergency remote teaching lasted longer than in other countries. The mandatory teaching modalities have required digital transformation processes in a framework where digital-divide is one of the limitations to school modernization. We believe that the experience can promote a deeper formatting of organizational process. The paper shows results of a multitarget research carried out during the Italian lockdown aiming at animating the debate around school from multi-actors perspectives and at supporting policies. The paper aims at showing the potentiality of a multivariate statistical method as a tool supporting school managers in identifying those challenges they have to face to improve the setting up of internal processes. The main result is a model supporting the decision making process at orienting school managers strategies.
