Three-dimensional transvaginal ultrasound vs magnetic resonance imaging for preoperative staging of deep myometrial and cervical invasion in patients with endometrial cancer: systematic review and meta-analysis.

OBJECTIVES: To evaluate and compare the diagnostic test accuracy (DTA) of three-dimensional transvaginal ultrasound (3D-TVS) and magnetic resonance imaging (MRI) for deep myometrial infiltration (DMI) and cervical invasion for preoperative staging and surgery planning in patients with endometrial cancer (EC). METHODS: This systematic review and meta-analysis investigated the DTA of MRI and 3D-TVS for DMI and cervical invasion in patients with EC. A literature search was performed using MEDLINE, Scopus, EMBASE, ScienceDirect, The Cochrane library, ClinicalTrials.gov, Cochrane Central Register of Controlled Trials, EU Clinical Trials Register and World Health Organization International Clinical Trials Registry Platform to identify relevant studies published between January 2000 and December 2021. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. RESULTS: Five studies, including a total of 450 patients, were included in the systematic review. All five studies compared the DTA of 3D-TVS vs MRI for DMI, and three studies compared the DTA of 3D-TVS vs MRI for cervical invasion. Pooled sensitivity, positive likelihood ratio and negative likelihood ratio for detecting DMI using 3D-TVS were 77% (95% CI, 66-85%), 4.57 and 0.31, respectively. The respective values for detecting DMI on MRI were 80% (95% CI, 73-86%), 4.22 and 0.24. Bivariate metaregression indicated a similar DTA of 3D-TVS and MRI (P = 0.80) for the correct identification of DMI. Pooled ln diagnostic odds ratio for detecting cervical invasion was 3.11 (95% CI, 2.09-4.14) for 3D-TVS and 2.36 (95% CI, 0.90-3.83) for MRI. The risk of bias was low for most of the four domains assessed in QUADAS-2. CONCLUSION: 3D-TVS demonstrated good diagnostic accuracy in terms of sensitivity and specificity for the evaluation of DMI and cervical invasion, with results comparable with those of MRI. Thus, we confirmed the potential role of 3D-TVS in the preoperative staging and surgery planning in patients with EC. © 2022 The Authors.

Pituitary block with gonadotrophin-releasing hormone antagonist during intrauterine insemination cycles: a systematic review and meta-analysis of randomised controlled trials.

BACKGROUND: Several randomised controlled trials (RCTs) have investigated the usefulness of pituitary block with gonadotrophin-releasing hormone (GnRH) antagonists during intrauterine insemination (IUI) cycles, with conflicting results. OBJECTIVE: The aim of the present systematic review and meta-analysis of RCTs was to evaluate the effectiveness of GnRH antagonist administration as an intervention to improve the success of IUI cycles. SEARCH STRATEGY: Electronic databases (MEDLINE, Scopus, EMBASE, Sciencedirect) and clinical registers were searched from their inception until October 2017. SELECTION CRITERIA: Randomised controlled trials of infertile women undergoing one or more IUI stimulated cycles with GnRH antagonists compared with a control group. DATA COLLECTION AND ANALYSIS: The primary outcomes were ongoing pregnancy/live birth rate (OPR/LBR) and clinical pregnancy rate (CPR). Pooled results were expressed as odds ratio (OR) or mean differences with 95% confidence interval (95% CI). Sources of heterogeneity were investigated through sensitivity and subgroups analysis. The body of evidence was rated using GRADE methodology. Publication bias was assessed with funnel plot, Begg's and Egger's tests. MAIN RESULTS: Fifteen RCTs were included (3253 IUI cycles, 2345 participants). No differences in OPR/LBR (OR 1.14, 95% CI 0.82-1.57, P = 0.44) and CPR (OR 1.28, 95% CI 0.97-1.69, P = 0.08) were found. Sensitivity and subgroup analyses did not provide statistical changes in pooled results. The body of evidence was rated as low (GRADE 2/4). No publication bias was detected. CONCLUSION: Pituitary block with GnRH antagonists does not improve OPR/LBR and CPR in women undergoing IUI cycles. TWEETABLE ABSTRACT: Pituitary block with GnRH antagonists does not improve the success of IUI cycles.

Risk of recurrent menorrhagia after hydrothermoablation: role of GnRH analogues neoadjuvant treatment in long-term successful rate.

OBJECTIVE: To evaluate the long-term effectiveness of presurgical therapy with GnRH analogues in patients who underwenthydrothermal endometrial ablation (HTA) for menorrhagia and assess the relationship between sonographically measured myometrium thickness and pelvic pain. MATERIALS AND METHODS: A prospective randomized control study comparing 15 women (Group A) with presurgical subcutaneous triptorelin depot injection before HTA with controls (Group B, n = 15). Inclusion criteria were: recurrent menorrhagia, uterus length < 12 cm, no previous hormonal therapy for at least six month, and family plan completed. Student's t test was applied, as appropriate, to compare continuous variables. Proportion were compared with chi-squared. RESULTS: After 12 months of follow-up, Group A showed a significantly lower (0% vs 20%; p = 0.03) failure rate after hydrothermoablation than the Group B and a generally higher successful rate at 24 and 48 months. The discomfort, evaluated with VAS, showed a mean value of 47.6 +/- 15.9 +/- SD); 96.7% of women reported a mild-moderate postoperative pain. No perioperative and late complications were recorded. CONCLUSIONS: Presurgical treatment with GnRH analogues seems to improve long-term efficacy of HTA. Perioperative pelvic pain seems to not be affected by myometrium thickness.

Accuracy of hysteroscopy made by young residents in detecting endometrial pathologies in postmenopausal women.

PURPOSE OF INVESTIGATION: The aim of the study was to analyze the diagnostic value of hysteroscopy made by young residents in evaluating uterine cavity compared to experienced hysteroscopists with histological diagnosis as reference in postmenopausal women, with particular attention to endometrial hyperplasia and cancer. MATERIALS AND METHODS: A total of 600 postmenopausal women that underwent diagnostic hysteroscopy (DH) between January 2011 and December 2013 were evaluated. The authors compared the first 200 hysteroscopic findings of each young resident with those of seniors that supervised all the procedures, regarding the same patients. Subsequent histological evaluation was obtained by operative hysteroscopy or endometrial biopsy. Residents' and seniors' data were compared with the final histological diagnosis established by anatomopathologist. RESULTS: No adverse effects such as vaso-vagal reactions or uterine perforations in DH neither in operative hysteroscopic procedures were reported. Hysteroscopy made by residents had 60%, 9.09%, and 70.4% sensitivity (SE) and 97.1%, 98.8%, and 99.1% specificity (SP) in detecting hyperplasia without atypia, hyperplasia with atypia, and endometrial cancer, respectively. On the other hand, DH made by seniors resulted in 85%, 72.7%, and 96.3% SE and 99.8%, 99.8%, and 100% SP, in detecting the same three histological findings. CONCLUSION: Outpatient hysteroscopy made by residents at their endoscopic experience beginning has good accuracy in detecting clear endometrial malignant lesions, unlike in detecting premalignant lesion as hyperplasia with atypia. This could signify that more than 200 hysteroscopies are necessary for a resident to well recognize premalignant and malignant lesions.

Laparoscopic surgical staging of endometrial cancer: does obesity influence feasibility and perioperative outcome?

AIM: Laparoscopic treatment of early-stage endometrial cancer is the gold standard to reduce perioperative morbidity. Obesity is a well-known risk factor for endometrial cancer and anesthesiological and surgical complications. The authors' aim was to examine the effect of body mass index (BMI) on perioperative parameters and complications in laparoscopically-treated patients with endometrial cancer. MATERIALS AND METHODS: A consecutive series of patients affected by endometrial cancer and their demographic and clinicopathological data were collected. Patients were divided in 41 non-obese (BMI or= 30) groups. All patients had been preoperatively evaluated with hysteroscopic procedures and toraco-abdominal computed tomography (CT) and had been submitted to laparoscopic radical hysterectomy according to Querleu-Morrow, pelvic lymphadenectomy, peritoneal washing, and bilateral adnexectomy. RESULTS: There was no statistically significant difference in blood loss, number of lymph nodes removed, and hospital stay between the groups, but there was a trend towards a lengthening of surgical time in the obese women. There were no major intraoperative and postoperative complications. DISCUSSION: This study demonstrates that laparoscopic approach is feasible and safe in obese women evaluating the anesthesiological risk.

Atypical endometrial lesions: hysteroscopic resection as an alternative to hysterectomy.

BACKGROUND: Endometrial hyperplasia is a precursor to endometrial carcinoma: the risk of progression to invasive endometrial cancer is increased in postmenopausal women and much more in cases of atypical endometrial hyperplasia (25%-30%). In addition, in 12.7% to 42.6% of cases according to various studies, endometrial cancer coexists in patients with diagnosis of atypical endometrial hyperplasia. The aim of this study was to evaluate the correlation between radical hysteroscopic resection of atypical endometrial lesions and the histopathological examination of the uterus. MATERIALS AND METHODS: The authors collected 25 patients referring to the Department of Woman and Child Health, in the University of Padua (Italy) from January 2008 to June 2012, undergoing hysteroscopic resection for atypical polyps and focal atypical endometrial hyperplasia, and following hysterectomy within 30 days. Average age, menopausal status, hormone replacement therapy, body mass index (BMI), presence of hypertension and diabetes, and taking tamoxifen were reported. RESULTS: After hysteroscopic resection in all patients atypical polyps and focal endometrial hyperplasia were confirmed. The hystopathologic evaluation of the uterus reported: in only two (8%) cases, the persistence of atypical endometrial lesion, whereas in 23 (92%) cases the endometrial tissue was negative for atypia or malignancy. CONCLUSIONS: Radical endometrial resection by hysteroscopy may serve as an alternative to hysterectomy in selected patients with atypical focal endometrial lesions, not only in fertile women, but also in patients who refuse hysterectomy or present high anesthesiologic and surgical risks, regardless of the risk of recurrence, and with the necessity of undergoing hysteroscopic close follow-up.

Comparison between transvaginal sonography, saline contrast sonovaginography and magnetic resonance imaging in the diagnosis of posterior deep infiltrating endometriosis.

OBJECTIVE: To compare clinical evaluation, transvaginal sonography (TVS), saline contrast sonovaginography (SCSV) and magnetic resonance imaging (MRI) in the diagnosis of posterior deep pelvic endometriosis (DPE). METHODS: Women suspected of having posterior DPE on the basis of subjective symptoms and clinical evaluation underwent digital vaginal and rectal examination, TVS, SCSV and MRI. Laparoscopy was performed and specimens were sent for histological examination. Sensitivity, specificity, positive and negative predictive value, as well as positive and negative likelihood ratios were analyzed for each diagnostic method. RESULTS: Fifty-four out of 102 women suspected of having posterior DPE underwent laparoscopic surgery. Among these, in 46 (85.2%) cases DPE was confirmed at laparoscopic and histological examination. SCSV correctly identified 43 (93.5%) cases, presenting higher accuracy than did the other procedures. SCSV and MRI were more accurate in diagnosing and discriminating between the different locations of endometriotic lesions, with respective sensitivities of 94.7 and 73.1% for vaginal fornix, 88.9 and 66.7% for the uterosacral ligaments and 80.6 and 83.3% for involvement of the rectovaginal septum. The specificity of SCSV and MRI, respectively, was 97.1 and 94.3% for vaginal fornix, 95.6 and 95.6% for uterosacral ligaments and 100 and 77.8% for involvement of the rectovaginal septum. In the diagnosis of rectal endometriosis, we found a sensitivity of 66.7% for both techniques and specificity of 93.8% for SCSV and 95.8% for MRI. CONCLUSION: TVS should be used as the first-line diagnostic technique and SCSV and/or MRI as second-line methods in the diagnosis of posterior DPE.

Lipid patterns in the saliva of smoking young adults.

Salivary lipids are important for the maintenance of oral cavity health. Elevated salivary lipid levels are associated with an increase of caries incidence, plaque development, calculus formation and periodontal disease. However, the regulation of lipid salivary levels is scarcely known. Cigarette smoke is considered a risk factor for oral cavity diseases. We study how cigarette smoke may affect the secretion of salivary lipids. To this purpose, we determine the salivary levels of cholesterol and of glycerolipids in saliva sampled from smokers and non-smokers at various times of day. We observe an increase of glycerophospholipid and a decrease of cholesterol levels in the smokers' saliva collected at 10 p.m. On the other hand, unsaturated fatty acids in chief phospholipids of saliva are lower in smokers at 7 a.m. Therefore, for the first time, we demonstrate that cigarette smoke induces variations of saliva lipid pattern in young people even moderately smoking.

Hysteroscopic permanent tubal sterilization using a nitinol-dacron intratubal device without anaesthesia in the outpatient setting: procedure feasibility and effectiveness.

BACKGROUND: Hysteroscopic permanent tubal sterilization has recently been introduced, resulting in a non-invasive, safe and effective technique. The aim of this study was to assess the feasibility of outpatient hysteroscopic tubal sterilization using a nitinol-dacron intratubal device without anaesthesia and to assess patient procedure compliance. MATERIALS AND METHODS: We untertook a prospective study of 36 consecutive cases of outpatient hysteroscopic tubal sterilization using a nitinol-dacron intratubal device without anaesthesia. Tubal sterilization was performed by placing the device with the aid of a 5.2-mm continuous-flow operative hysteroscope. At the end of the procedure women were asked to rate the pain experienced on a visual analogue scale (VAS) (0, no discomfort to 100, severe discomfort). Successful device placement was assessed after 3 months by hysterosalpingography and diagnostic hysteroscopy. RESULTS: Successful bilateral placement was obtained in 32 patients (88.9%); in one (2.8%) the placement was monolateral; and in three (8.3%) the procedure failed. Mean operating time was 8.6 +/- 5.3 min. A mean VAS of 36.1 +/- 23.9 was recorded. CONCLUSIONS: The nitinol-dacron intratubal device is safe, appears to be effective long-term, is non-invasive and can be used in the outpatient setting without anaesthesia. Low-level discomfort was experienced by the patients. Limitations of its use include that it is not effective immediately, it is irreversible, it requires special equipment and training, and it is difficult to use in cases of uterine anomalies. We conclude that this method may be offered to all woman asking for permanent tubal sterilization, particularly those who refuse or have contraindications for anaesthesia.

Adenosarcoma of the ovary. A case report.

Adenosarcoma of the ovary is a rare condition. We report a case of a 32-year-old patient that has been treated in our Department. The diagnosis of ovarian adenosarcoma was carried out after laparoscopy with removal of an ovarian endometriotic cyst. Laparoscopic homolateral ovariectomy was then performed and conservative treatment was decided on considering the young age, low stage and low grade of the disease. Second-look laparoscopy, clinical evaluation and ultrasound were performed for four years of follow-up. No recurrence has been detected. Conservative treatment should be proposed in fertile age with low-grade ovarian adenosarcoma, but a strict follow-up is always necessary.

Laparoscopic management of early stage endometrial cancer.

PURPOSE OF INVESTIGATION: The purpose of this study was to evaluate the feasibility of laparoscopic hysterectomy versus the transabdominal approach with systemic pelvic lymphadenectomy in early stage endometrial cancer. METHODS: From January 1996 to April 2002, 59 women were treated for endometrial cancer at the Department of Gynecology in Padova, Italy (29 by the laparoscopic technique and 30 by laparotomy). Every patient underwent hysterosalpingo-oophorectomy with systemic pelvic lymphadenectomy. RESULTS: Comparing the two techniques, operating time was longer and hospital stay was significantly shorter for laparoscopy; no differences were observed about the number of removed lymph nodes (range 5-33) or intra-postoperatory complications. CONCLUSION: The laparoscopic approach to endometrial cancer is certainly to be considered appropriate and efficacious, even if it requires skilled surgeons and adequate oncologic training. It is important to perform pelvic lymphadenectomy in all cases of early stage cancer.
