Ovarian tissue biopsy for cryopreservation by vaginal natural orifice transluminal endoscopic surgery: a new approach for a minimal invasive ovarian biopsy.

OBJECTIVE: Vaginal natural orifice transluminal endoscopic surgery (vNOTES) is an emerging surgical procedure that combines the advantages of the vaginal approach with laparoscopic vision and instrumentation. Shorter hospitalization and lesser postoperative pain associated with vNOTES may be explained by the advantages of this innovative surgical approach (e.g., absence of abdominal incisions, shorter operative time, and lower insufflation pressure). Ovarian tissue cryopreservation allows to preserve reproductive and endocrine functions in young women with oncological disease at risk of premature ovarian insufficiency (POI) caused by gonadotoxic treatments. Ovarian tissue biopsy for cryopreservation consists of a large biopsy of 1 or both ovaries that is usually performed by laparoscopy. Then, the removed ovarian tissue is cryopreserved for the future transplant after cancer remission. The volume of ovarian biopsy ranges from 50% of the ovary for women at moderate risk of POI to 70%-100% of it for those at high risk. The inclusion criteria for ovarian tissue cryopreservation are women aged <35 years who cannot delay start of oncological treatments for follicle cryopreservation, with a moderate or high risk of POI and good chance of 5-year survival. Ovarian tissue cryopreservation cannot be performed if tumor treatments include uterine irradiation or for tumors at risk of ovarian metastases (as in the case of ovarian cancer, leukemia, neuroblastoma, or Burkitt lymphoma). Despite widespread adoption of vNOTES in gynecology, ovarian biopsy for cryopreservation has never been performed using this route. DESIGN: Step-by-step explanation of the procedure with descriptive text and narrated video footage. SETTING: Tertiary-level referral academic center. PATIENT(S): A 27-year-old patient recently diagnosed with low-grade follicular non-Hodgkin lymphoma was referred to our center for ovarian tissue cryopreservation before chemotherapy. The patient included in this study gave informed consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites (e.g., PubMed, ScienceDirect, and Scopus), and other applicable sites. Because of the nature of the study, institutional review board approval was not required. INTERVENTION(S): Access to the peritoneal cavity was created by a 3-cm posterior colpotomy. The peritoneum was then opened using cold scissors and temporarily fixed to the posterior vaginal wall. The GelPOINT Mini Advanced Access Platform (Applied Medical, Rancho Santa Margarita, CA), with 1 10-mm and 2 5-mm trocars, was used as the vNOTES port. The inner Alexis ring of the GelPOINT was inserted through the colpotomy into the pouch of Douglas. A hysterometer was placed into the uterine cavity to keep the uterus anteverted during the surgery. A pneumoperitoneum was created to a pressure of 8 mm Hg, and the operating table was tilted to a 20° Trendelenburg position. A 10-mm rigid 30° camera was inserted in the inferior and larger trocar, and both ovaries were visualized. Seventy percent of the left ovary was removed with cold scissors to minimize trauma on the surgical specimen. After removal of the GelPOINT cap, ovarian biopsy was immediately picked up by the biologist of our fertility center. The ovary was coagulated with a bipolar instrument. The hysterometer was then replaced by a uterine manipulator to perform tubal patency test, and blue dye passage through both salpinges was observed. Finally, the Alexis retractor and stich on the posterior peritoneum were removed, and the vagina was sutured using interrupted stiches. The total operative time was 25 minutes. MAIN OUTCOMES MEASURE(S): Ovarian tissue biopsy for cryopreservation by vNOTES. RESULT(S): No intraoperative and postoperative complications were reported, and the patient was discharged after 24 hours from surgery. CONCLUSION(S): Vaginal natural orifice transluminal endoscopic surgery may be a feasible alternative approach to laparoscopy for ovarian tissue cryopreservation: it allows an easy access to the ovaries and removal of different tissue volumes. Patients undergoing ovarian cryopreservation may benefit from the vNOTES approach because a rapid postoperative recovery is crucial to start chemotherapy in a short time. As for other vNOTES procedures, accurate selection of patients seems to be crucial for a successful ovarian tissue cryopreservation. We believe that the inclusion and exclusion criteria reported for other gynecologic procedures performed through vNOTES may also be valid for ovarian tissue cryopreservation by vNOTES. Women at high risk of pelvic adhesions (e.g., coexistent endometriosis, previous pelvic surgery, or inflammatory pelvic disease), those with an increased body mass index or enlarged uterus, and those with cervical, vaginal, or uterine cancer cannot be considered for this approach because all these factors are associated with failure of vNOTES. On the other hand, women with no history of surgery, endometriosis, and large myomas may benefit from the vNOTES approach, and these women represent most of patients who undergo ovarian tissue cryopreservation. Further and larger studies are needed to assess the efficacy and safety of this new approach.

Detection and Classification of Hysteroscopic Images Using Deep Learning.

BACKGROUND: Although hysteroscopy with endometrial biopsy is the gold standard in the diagnosis of endometrial pathology, the gynecologist experience is crucial for a correct diagnosis. Deep learning (DL), as an artificial intelligence method, might help to overcome this limitation. Unfortunately, only preliminary findings are available, with the absence of studies evaluating the performance of DL models in identifying intrauterine lesions and the possible aid related to the inclusion of clinical factors in the model. AIM: To develop a DL model as an automated tool for detecting and classifying endometrial pathologies from hysteroscopic images. METHODS: A monocentric observational retrospective cohort study was performed by reviewing clinical records, electronic databases, and stored videos of hysteroscopies from consecutive patients with pathologically confirmed intrauterine lesions at our Center from January 2021 to May 2021. Retrieved hysteroscopic images were used to build a DL model for the classification and identification of intracavitary uterine lesions with or without the aid of clinical factors. Study outcomes were DL model diagnostic metrics in the classification and identification of intracavitary uterine lesions with and without the aid of clinical factors. RESULTS: We reviewed 1500 images from 266 patients: 186 patients had benign focal lesions, 25 benign diffuse lesions, and 55 preneoplastic/neoplastic lesions. For both the classification and identification tasks, the best performance was achieved with the aid of clinical factors, with an overall precision of 80.11%, recall of 80.11%, specificity of 90.06%, F1 score of 80.11%, and accuracy of 86.74 for the classification task, and overall detection of 85.82%, precision of 93.12%, recall of 91.63%, and an F1 score of 92.37% for the identification task. CONCLUSION: Our DL model achieved a low diagnostic performance in the detection and classification of intracavitary uterine lesions from hysteroscopic images. Although the best diagnostic performance was obtained with the aid of clinical data, such an improvement was slight.

Comparison of perioperative surgical outcomes between contained and free manual vaginal morcellation of large uteruses following total laparoscopic hysterectomy.

OBJECTIVE: To compare contained and free manual vaginal morcellation of large uteruses after total laparoscopic hysterectomy (TLH) in women at low risk of uterine malignancy in terms of feasibility and safety. METHODS: A single-center, observational, retrospective, cohort study was carried out including all patients undergoing TLH requiring manual vaginal morcellation for specimen extraction of large uteruses from January 2015 to August 2021 at the Division of Gynecology and Human Reproduction Physiopathology, IRCCS Azienda Ospedaliero-Universitaria of Bologna, Bologna, Italy. Patients were divided into two groups according to the type of manual vaginal morcellation (contained or free), and compared in terms of demographic, clinical, and perioperative data. RESULTS: In all, 271 patients were included: 186 (68.6%) in the contained morcellation group and 85 (31.4%) in the free morcellation group. The mean operative time was significantly lower in the contained morcellation group compared with the free morcellation group (median [interquartile range] 130 [45] vs. 155 [60] min; P < 0.001). No significant difference was found in complications related to the morcellation step, overall, intraoperative and postoperative complications, estimated blood loss, length of hospital stays, uterine weight, and rate of occult malignancy between the two groups. CONCLUSION: Contained vaginal manual morcellation of the uterus after total laparoscopic hysterectomy using a specimen retrieval bag appears to be a safe procedure with significantly lower operative time than free vaginal manual morcellation.

Molecular Signature of Endometrial Cancer with Coexistent Adenomyosis: A Multicentric Exploratory Analysis.

Adenomyosis has been associated with better survival outcomes in women with endometrial cancer. However, although the endometrial cancer patients' risk stratification has been revolutionized by molecular findings, the impact of the molecular signature on the favorable prognosis of endometrial cancer patients with coexistent adenomyosis is unknown. The aim of our study was to compare the prevalence of molecular groups at poor and intermediate prognosis between endometrial cancer patients with and without coexistent adenomyosis. A multicentric, observational, retrospective, cohort study was performed to assess the differences in the prevalence of p53-abnormal expression (p53-abn) and mismatch repair protein-deficient expression (MMR-d) signatures between endometrial cancer patients with and without coexistent adenomyosis. A total of 147 endometrial cancer patients were included in the study: 38 in the adenomyosis group and 109 in the no adenomyosis group. A total of 37 patients showed the MMR-d signature (12 in the adenomyosis group and 25 in the no adenomyosis group), while 12 showed the p53-abn signature (3 in the adenomyosis group and 9 in the no adenomyosis group). No significant difference was found in the prevalence of p53-abn (p = 1.000) and MMR-d (p = 0.2880) signatures between endometrial cancer patients with and without coexistent adenomyosis. In conclusion, the molecular signature does not appear to explain the better prognosis associated with coexistent adenomyosis in endometrial cancer patients. Further investigation of these findings is necessary through future larger studies.

Race and ethnicity reporting in endometrial cancer literature.

OBJECTIVES: There is evidence that there are differences in survival outcomes among patients with endometrial cancer of different ethnic groups. We aimed to assess the quantity and quality of race/ethnicity reporting in the literature on endometrial cancer published from January 2020 to December 2020. METHODS: In this systematic review, electronic searches of PubMed, MEDLINE, Web of Sciences, Scopus, and Cochrane Library databases were performed for all articles published in 2020. A total of 3330 articles were reviewed, of which 949 (35%) peer-reviewed human-based articles focusing on endometrial cancer were included. Non-research-focused articles, review articles, meta-analyses, case reports, and non-human studies were excluded. We analyzed the proportion of studies reporting race/ethnicity and assessed the quality of reporting with regard to the adherence to the International Committee of Medical Journal Editors (ICMJE) recommendations. We evaluated the influence of study characteristics on race/ethnicity reporting and compared articles published in journals which adhere to the ICMJE recommendations against those that did not explicitly state that they did. RESULTS: Of the 949 (28.5%) included articles, 166 (17.5%) reported race/ethnicity of patients, with low quality of reporting. The reporting rate of race/ethnicity was similar when comparing articles from ICMJE and non-ICMJE journals (62 (20.4%) vs 104 (16.1%); p=0.11), prospective versus retrospective studies (53 (22.7%) vs 113 (15.8%); p=0.02), and national versus international studies (147 (17.5%) vs 19 (17.4%); p=0.99). Studies performed in the WHO region of Americas were significantly more consistent in reporting race compared with other regions (119 (44.7%) vs 23 (6.8%) European, 2 (7.4%) Eastern Mediterranean, 21 (7.1%) Western Pacific, 0 (0%) South-East Asia; p<0.001). Female corresponding authors were significantly more consistent in reporting race than male authors (94 (22.5%) vs 72 (13.6%); p<0.001). CONCLUSIONS: Human-based articles focusing on endometrial cancer have a low frequency and quality of race/ethnicity reporting, even in journals claiming to follow ICMJE recommendations.

Endometrial Cancer Arising in Adenomyosis (EC-AIA): A Systematic Review.

Endometrial cancer arising in adenomyosis (EC-AIA) is a rare uterine disease characterized by the malignant transformation of the ectopic endometrium within the adenomyotic foci. Clinicopathological and survival data are mostly limited to case reports and a few cohort studies. We aimed to assess the clinicopathological features and survival outcomes of women with EC-AIA through a systematic review of the literature. Six electronic databases were searched, from 2002 to 2022, for all peer-reviewed studies that reported EC-AIA cases. Thirty-seven EC-AIA patients from 27 case reports and four case series were included in our study. In our analysis, EC-AIA appeared as a rare disease that mainly occurs in menopausal women, shares symptoms with endometrial cancer, and is challenging to diagnose preoperatively. Differently from EC, it shows a higher prevalence of the non-endometrioid histotype, advanced FIGO stages, and p53-signature, which might be responsible for its worse prognosis. Future studies are necessary, to confirm our findings and further investigate this rare condition.

Prevalence and Risk Factors of Central Sensitization in Women with Endometriosis.

STUDY OBJECTIVE: To assess prevalence of central sensitization (CS) and its association with demographic and clinical factors in patients with endometriosis. DESIGN: Single-center, observational, cross-sectional study. SETTING: Tertiary center. PATIENTS: Consecutive patients with endometriosis referred to the center from January 15, 2022, to April 30, 2022. INTERVENTIONS: For each enrolled patient, demographic and clinical data were collected, and the presence of CS was measured using the CS Inventory questionnaire (score ≥40). MEASUREMENTS AND MAIN RESULTS: Primary study outcome was CS prevalence, and secondary study outcomes were the associations between demographic and clinical factors and CS. The 95% confidence intervals for CS prevalence were obtained with Bayesian-derived Jeffreys method, and the associations between CS and demographic and clinical factors were evaluated with the chi-square test and Fisher's exact test, where appropriate. The variables significantly associated with CS were then included in a multivariable logistic regression model. The significance level was set at .05 for all analyses. During the study period, 285 eligible women were enrolled. CS prevalence was 41.4% (95% confidence interval, 35.8-47.2). At univariable analysis, infertility, moderate to severe pain symptoms (except for dyschezia), altered bowel movements, posterolateral parametrium involvement, hormonal therapy failure (HTF), and most of central sensitivity syndromes were significantly associated with CS occurrence. Multivariable analysis only confirmed the significant association of CS with moderate to severe chronic pelvic pain, posterolateral parametrium involvement, HTF, migraine or tension-type headache, irritable bowel syndrome, and anxiety or panic attacks. CONCLUSION: CS has a high prevalence in patients with endometriosis, especially in those with moderate to severe chronic pelvic pain, posterolateral parametrium involvement, HTF, and 3 central sensitivity syndromes (i.e. migraine or tension-type headache, irritable bowel syndrome, anxiety or panic attacks). Given the association with HTF, identifying CS through CS Inventory might be useful to counsel the patient and to choose multimodal treatment.

Clinical, laboratory and ultrasonographic risk factors for uterine artery arteriosclerosis: Insights for uterus transplantation.

OBJECTIVE: To assess uterine artery arteriosclerosis prevalence in women undergoing total hysterectomy for benign diseases, and any associations between clinical, laboratory, and ultrasound factors and uterine artery arteriosclerosis occurrence. METHODS: A single center, observational, prospective, cohort study was performed enrolling all symptomatic patients scheduled for total hysterectomy from May to December 2021. Our outcomes were: uterine artery arteriosclerosis prevalence and the difference in clinical, laboratory, and ultrasonographic factors between patients with and without uterine artery arteriosclerosis. RESULTS: Forty women were included. Uterine artery arteriosclerosis prevalence was 70%. Body mass index (BMI) (P = 0.04) and triglycerides (P = 0.04) were significantly higher in patients with uterine artery arteriosclerosis than in patients without; while high-density lipoprotein (HDL) (P = 0.02) was significantly lower. Uterine arteries with arteriosclerosis showed higher peak systolic velocity (PSV) values compared with vessels without arteriosclerosis (P = 0.05). CONCLUSIONS: Uterine artery arteriosclerosis shows a high prevalence in women undergoing total hysterectomy for benign diseases. Higher BMI, serum triglycerides, and PSV, and lower serum HDL appear as risk factors for uterine artery arteriosclerosis.

Laparoscopic entry techniques: Which should you prefer?

BACKGROUND: Despite a debate spanning two decades, no consensus has been achieved about the safest laparoscopic entry technique. OBJECTIVES: To update the evidence about the safety of the main different laparoscopic entry techniques. SEARCH STRATEGY: Six electronic databases were searched from inception to February 2021. SELECTION CRITERIA: All randomized controlled trials (RCTs) comparing different laparoscopic entry techniques were included. DATA COLLECTION AND ANALYSIS: Entry-related complications and total time for entry were compared among the different methods of entry calculating pooled odds ratios (ORs) and mean differences, with 95% confidence intervals (CIs); P < 0.05 was considered significant. MAIN RESULTS: In total, 25 RCTs (6950 patients) were included. Complications considered were vascular, visceral and omental injury, failed entry, extraperitoneal insufflation, bleeding and infection at the trocar site bleeding, and incisional hernia. Compared to direct trocar, the OR for Veress needle was significantly higher for omental injury (OR 3.65, P < 0.001), for failed entry (OR 4.19, P < 0.001), and for extraperitoneal insufflation (OR 5.29, P < 0.001). Compared to the open method, the OR for Veress needle was significantly higher for omental injury (OR 4.93, P = 0.001), for failed entry (OR 2.99, P < 0.001), for extraperitoneal insufflation (OR 4.77; P = 0.04), and for incisional hernia. Compared to the open method, the OR for direct trocar was significantly lower for visceral injury (OR 0.17, P = 0.002) and for trocar site infection (OR 0.27, P = 0.001). CONCLUSIONS: The direct trocar method may be preferred over Veress needle and open methods as a laparoscopic entry technique since it appears associated to a lower risk of complications.

The impact of hysterectomy on oncological outcomes in postmenopausal patients with borderline ovarian tumors: A multicenter retrospective study.

Data about the oncological outcomes in women with borderline ovarian tumor (BOT) undergoing uterine-sparing surgery without ovarian preservation are poor. We aimed to assess the oncological outcomes in women with BOT undergoing uterine-sparing surgery without ovarian preservation. A multi-center observational retrospective cohort study was performed including all consecutive postmenopausal patients who underwent surgical treatment for BOT at three tertiary level referral centers for gynecologic oncology from January 2005 to December 2016. Patients were divided into two groups for comparisons: patients undergoing hysterectomy (hysterectomy group) and patients undergoing uterine-sparing surgery (no hysterectomy group). Study outcomes were disease-free survival (DFS), overall survival (OS), disease-specific survival (DSS) and surgical complications rate. Ninety-eight patients were included: 44 in the hysterectomy group and 54 in the no hysterectomy group. The 5- and 10-year DFS rates were 97.7% (95% CI: 84.9-99.7) and 92.3% (95% CI: 69.7-98.2), in the hysterectomy group, and 86.8% (95% CI: 74.3-93.5) and 86.8% (95% CI: 74.3-93.5), in the no hysterectomy group, respectively, without significant differences (p=0.16). Hazard ratio for DFS was 0.26 (95% CI: 0.06-1.68) for the hysterectomy group. The 5- and 10-year OS rates were 100.0% (95% CI: -) and 100.0% (95% CI: -), in the hysterectomy group, and 98.2% (95% CI: 87.6-99.7) and 94.4% (95% CI: 77.7-98.7), in the no hysterectomy group, respectively, without significant differences (p=0.23). No significant difference in complication rate was reported among the groups (p=0.48). As hysterectomy appears to not impact survival outcomes of women with BOT, it might be avoided in the surgical staging.

Sentinel Lymph Node Biopsy in Surgical Staging for High-Risk Groups of Endometrial Carcinoma Patients.

BACKGROUND: In endometrial carcinoma (EC) patients, sentinel lymph node (SLN) biopsy has shown the potential to reduce post-operative morbidity and long-term complications, and to improve the detection of low-volume metastasis through ultrastaging. However, while it has shown high sensitivity and feasibility in low-risk EC patient groups, its role in high-risk groups is still unclear. AIM: To assess the role of SLN biopsy through the cervical injection of indocyanine green (ICG) in high-risk groups of early-stage EC patients. MATERIALS AND METHODS: Seven electronic databases were searched from their inception to February 2021 for studies that allowed data extraction about detection rate and accuracy of SLN biopsy through the cervical injection of ICG in high-risk groups of early-stage EC patients. We calculated pooled sensitivity, false negative (FN) rate, detection rate of SLN per hemipelvis (DRh), detection rate of SLN per patients (DRp), and bilateral detection rate of SLN (DRb), with 95% confidence interval (CI). RESULTS: Five observational cohort studies (three prospective and two retrospective) assessing 578 high risk EC patients were included. SLN biopsy sensitivity in detecting EC metastasis was 0.90 (95% CI: 0.03-0.95). FN rate was 2.8% (95% CI: 0.6-11.6%). DRh was 88.4% (95% CI: 86-90.5%), DRp was 96.6% (95% CI: 94.7-97.8%), and DRb was 80% (95% CI: 75.4-83.9). CONCLUSION: SLN biopsy through ICG cervical injection may be routinely adopted instead of systematic pelvic and para-aortic lymphadenectomy in surgical staging for high-risk groups of early-stage EC patients, as well as in low-risk groups.

Histological Prognostic Factors of Endometrial Cancer in Patients with Adenomyosis: A Systematic Review and Meta-Analysis.

BACKGROUND: A better endometrial cancer (EC) prognosis in patients with coexistent adenomyosis has been hypothesized based on a different prevalence of favorable EC histological prognostic factors. However, pooled risk of EC unfavorable histological prognostic factors in patients with adenomyosis has never been calculated. OBJECTIVES: We aimed to assess the risk of EC unfavorable histological prognostic factors in patients with adenomyosis. METHODS: All studies with data about histological prognostic factors of EC in patients with and without adenomyosis were included. Relative risk for each unfavorable histological prognostic factor of EC, such as nonendometrioid histotype, FIGO grade 3, FIGO stage II-IV, lymphovascular space invasion (LVSI), and deep myometrial invasion, was calculated in patients with adenomyosis compared to patients without adenomyosis. RESULTS: Seven studies with 4,439 patients were included in the quantitative analysis. EC patients with adenomyosis showed a pooled RR of 0.77 (p = 0.05) for nonendometrioid histotype, 0.55 (p < 0.00001) for FIGO grade 3, 0.60 (p = 0.005) for FIGO stage II-IV, 0.75 (p = 0.004) for LVSI, and 0.65 (p = 0.001) for deep myometrial invasion. CONCLUSION: EC patients with adenomyosis have a significantly decreased risk for unfavorable histological prognostic factors of EC compared to EC patients without adenomyosis. Such findings might explain the supposed better EC prognosis in patients with adenomyosis.

Cost-effectiveness analysis of ovarian tissue cryopreservation and transplantation for preservation of fertility in post-pubertal oncological women submitted to high-risk gonadotoxic chemotherapy.

OBJECTIVE: To study the economic impact of ovarian tissue cryopreservation and transplantation (OTC) in post-pubertal patients who underwent high-risk gonadotoxic chemotherapy. METHODS: A decision tree model was used to determine the live birth rate and cost-effectiveness of OTC versus non-OTC. The incremental cost-effectiveness ratio (ICER) was calculated. A sensitivity analysis was performed under the assumption that the costs of ovarian cortex retrieval, cryopreservation, and storage for patients with cancer might be covered by the national health system or health insurance. RESULTS: Patients had the greatest probability of achieving live birth after high-risk chemotherapy when they underwent OTC versus non-OTC. Although cryopreservation of ovarian tissue results in higher live birth rates, it is always more expensive. Cost-effectiveness increases when the majority of patients completes the path of tissue cryopreservation plus transplantation after 5 years. CONCLUSION: Although OCT has been demonstrated as a procedure for effective fertility preservation in fertility-age women with cancer, no cost-effectiveness analysis has been performed until now. This model could help healthcare systems to allocate coverage for OCT.

3D Patient-Specific Virtual Models for Presurgical Planning in Patients with Recto-Sigmoid Endometriosis Nodules: A Pilot Study.

Background and Objective: In recent years, 3D printing has been used to support surgical planning or to guide intraoperative procedures in various surgical specialties. An improvement in surgical planning for recto-sigmoid endometriosis (RSE) excision might reduce the high complication rate related to this challenging surgery. The aim of this study was to build novel presurgical 3D models of RSE nodules from magnetic resonance imaging (MRI) and compare them with intraoperative findings. Materials and Methods: A single-center, observational, prospective, cohort, pilot study was performed by enrolling consecutive symptomatic women scheduled for minimally invasive surgery for RSE between November 2019 and June 2020 at our institution. Preoperative MRI were used for building 3D models of RSE nodules and surrounding pelvic organs. 3D models were examined during multi-disciplinary preoperative planning, focusing especially on three domains: degree of bowel stenosis, nodule's circumferential extension, and bowel angulation induced by the RSE nodule. After surgery, the surgeon was asked to subjectively evaluate the correlation of the 3D model with the intra-operative findings and to express his evaluation as "no correlation", "low correlation", or "high correlation" referring to the three described domains. Results: seven women were enrolled and 3D anatomical virtual models of RSE nodules and surrounding pelvic organs were generated. In all cases, surgeons reported a subjective "high correlation" with the surgical findings. Conclusion: Presurgical 3D models could be a feasible and useful tool to support surgical planning in women with recto-sigmoidal endometriotic involvement, appearing closely related to intraoperative findings.

Pelvic floor dysfunction at transperineal ultrasound and chronic constipation in women with endometriosis.

OBJECTIVE: To assess the association between sonographic findings at transperineal ultrasound (TPU) and chronic constipation (CC) in women with endometriosis. METHODS: An observational prospective cohort study was performed by enrolling all women with endometriosis scheduled for surgery between September 2019 and October 2020. Women underwent TPU at rest and during Valsalva maneuver evaluating levator-hiatal-area (LHA), antero-posterior diameter (APD), and levator ani muscle (LAM) coactivation. Ultrasound findings were compared between women with and without CC in the whole study population, and subsequently in two subgroups (only ovarian endometriosis and deep infiltrating endometriosis [DIE]). RESULTS: In all, 87 women were enrolled: 29 (33%) with CC and 58 (67%) without CC. Women with endometriosis and CC showed a smaller LHA during Valsalva, less LHA and APD enlargement from rest to maximum Valsalva, and a higher prevalence of LAM coactivation compared with women without CC. In the ovarian subgroup, women with CC had smaller LHA at Valsalva, less enlargement of LHA and APD from rest to maximum Valsalva, and higher prevalence of LAM coactivation compared with non-CC patients. In the DIE subgroup, TPU did not significantly differ between CC and non-CC patients. CONCLUSION: TPU signs of pelvic floor muscle hypertonia are more frequent in endometriosis patients with CC compared with those without constipation, particularly in women affected by isolated ovarian endometriosis.

Impact of nerve-sparing posterolateral parametrial excision for deep infiltrating endometriosis on postoperative bowel, urinary, and sexual function.

OBJECTIVE: To evaluate the functional outcomes of nerve-sparing surgery for deep infiltrating endometriosis (DIE) with or without posterolateral parametrectomy. METHODS: A multicenter, observational, retrospective, cohort study was performed including all symptomatic women who underwent nerve-sparing laparoscopic excision of DIE and preoperative and postoperative assessment of functional outcomes through validated questionnaires between April 2019 and March 2020. Women with posterolateral parametrial DIE (P-group) and women with no parametrial involvement (NP-group) were compared in terms of preoperative and postoperative functional outcomes related to pelvic organs assessed through validated questionnaires (KESS and GIQLI for bowel function, BFLUTS for urinary function, and FSFI for sexual function); pain symptoms at 3-month follow up assessed through an 11-point visual analogue scale (VAS) for dyschezia, dysmenorrhea, dyspareunia and chronic pelvic pain; surgical outcomes; and rate of urinary voiding dysfunction at 3-month follow up. RESULTS: One-hundred patients were included: 69 in the P-group and 31 in the NP-group. Preoperative and postoperative values of questionnaires, pain symptoms, and postoperative complication rates were comparable between the two groups, except for postoperative dyspareunia and sexual dysfunction, which were statistically higher in the P-group. Only patients in the P-group experienced urinary voiding dysfunction, but no statistical significance was reached (P = 0.173). CONCLUSION: Posterolateral parametrectomy for DIE appears to be associated with a higher risk of postoperative dyspareunia and sexual dysfunction.

The impact of hysterectomy on oncological outcomes in patients with borderline ovarian tumors: A systematic review and meta-analysis.

BACKGROUND: Surgical management of Borderline ovarian tumors (BOT) can range from unilateral cystectomy to a more extensive surgical staging. However, the role of hysterectomy within the surgical staging is still debated. AIM: To assess the impact of hysterectomy on survival outcomes in BOT patients. MATERIALS AND METHODS: 5 electronic databases were searched from their inception to April 2021 for all peer-reviewed, retrospective or prospective studies, which compared treatment including hysterectomy versus treatment not including hysterectomy for BOT, in terms of recurrence and/or death. Pooled odds ratios (OR) with 95% confidence interval for recurrence, death due to BOT and death of any cause were calculated comparing hysterectomy group versus no hysterectomy group. Subgroup analyses for recurrence were based on BOT histotype (mucinous and serous) and FIGO stage (I and II-III). RESULTS: Twelve studies assessing 2223 patients were included. Compared to no hysterectomy group, hysterectomy group showed an OR of 0.23 (p = 0.00001) for recurrence, 1.26 (p = 0.77) for death due to BOT and 4.23 (p = 0.11) for death of any cause. At subgroup analyses, compared to no hysterectomy group, hysterectomy group showed an OR for recurrence of 0.21 (p = 0.003) in serous subgroup, of 0.46 (p = 0.18) in mucinous subgroup, of 0.23 (p = 0.0006) in FIGO stage I subgroup, and of 0.29 (p = 0.04) in FIGO stage II-III subgroup. CONCLUSIONS: Uterine-sparing surgery might be recommended in all BOT patients since it seems to increase the risk of recurrence, but not those of death due to disease or death of any cause.

Lymphovascular space invasion in endometrial carcinoma: A prognostic factor independent from molecular signature.

BACKGROUND: The 2020 ESGO/ESTRO/ESP guidelines stratify the prognosis of endometrial carcinoma (EC) patients combining The Cancer Genome ATLAS (TCGA) molecular signature and pathological factors, including lymphovascular space invasion (LVSI). However, little is known about the prognostic independence of LVSI from molecular signature. AIM: To assess whether the prognostic value of LVSI is independent from the TCGA signature. MATERIAL AND METHODS: A systematic review and meta-analysis was performed by searching 5 electronic databases from their inception to March 2021. All peer-reviewed studies reporting assessing LVSI as a prognostic factor independent from the TCGA groups in EC were included. Multivariate HRs with 95% confidence interval (CI) were pooled separately for overall survival (OS), disease-specific survival (DSS) and disease-free survival (DFS). The absence of LVSI was considered as a reference. In DFS analyses, locoregional and distant recurrence were separately considered for one study. RESULTS: Six studies with 3331 patients were included in the systematic review and three studies with 2276 patients in the meta-analysis. LVSI showed a pooled multivariate HR of 1.818 (CI 95%, 1.378-2.399) for OS, 1.849 (CI 95%, 1.194-2.863) for DSS, 1.377 (CI 95%, 1.008-1.880) for DFS excluding one study, 1.651 (CI 95%, 1.044-2.611) for DFS additionally considering locoregional recurrence from one study, and 1.684 (CI 95%, 1.05-2.701) for DFS additionally considering distant recurrence from the same study. CONCLUSION: LVSI has a prognostic value independent of TCGA signature, as well as age and adjuvant treatment, increasing the risk of death of any cause, death due to EC and recurrent or progressive disease by 1.5-2 times.

Impact of adenomyosis on the prognosis of patients with endometrial cancer.

BACKGROUND: Despite the high prevalence of adenomyosis in hysterectomy specimens of endometrial carcinoma (EC) patients, the relationship between adenomyosis and EC prognosis appears unclear. OBJECTIVE: To assess the prognostic value of coexistent adenomyosis in patients with EC. METHODS: A systematic review and meta-analysis was performed by searching six electronic databases for studies reporting data on prognosis of EC patients with and without coexistent adenomyosis. Studies with patient selection based on prognostic factors were excluded. Pooled univariate hazard ratio (HR) analyses for overall survival (OS) and disease-free survival (DRF) were performed, using EC patients without adenomyosis as a control group. For DFS, pooled multivariate HR analysis was also evaluable. RESULTS: Three studies of 2505 EC patients (553 with and 1952 without adenomyosis) were included. Compared with EC patients without adenomyosis, EC patients with coexistent adenomyosis showed a pooled HR of 0.533 (CI 95%, 0.329-0.864) for OS at univariate analysis; 0.536 (CI 95%, 0.334-0.859) for DFS at univariate analysis; and 0.875 (CI 95%, 0.331-2.315) for DFS at multivariate analysis. CONCLUSION: In EC patients with coexistent adenomyosis, the risk of death is halved compared with EC patients without adenomyosis. However, the independence of this association needs to be verified in future studies.

C-reactive Protein for Predicting Early Postoperative Complications in Patients Undergoing Laparoscopic Shaving for Deep Infiltrating Endometriosis.

STUDY OBJECTIVE: To assess the accuracy of C-reactive protein (CRP) in predicting early postoperative complications in patients undergoing elective laparoscopic shaving for rectosigmoid deep infiltrating endometriosis (DIE). DESIGN: A single-center observational retrospective cohort study. SETTING: Third-level referral center for endometriosis. PATIENTS: A total of 294 patients were included in the study. All of them underwent elective laparoscopic shaving for rectosigmoid DIE. INTERVENTIONS: Postoperative CRP levels (assessed from day 3 onward, every 48 hours, until hospital discharge) and early postoperative complications were reviewed to assess CRP as a predictive marker of postoperative complications. MEASUREMENTS AND MAIN RESULTS: The study outcomes were the association between early postoperative complications and CRP levels, the optimal CRP cutoff, and its predictive accuracy. Twenty-five patients (8.5%) experienced early postoperative complications. Five patients with postoperative complications within 2 days of surgery were excluded from the analysis. On postoperative day 3 the difference in the means of CRP levels between patients with and without complications was 2.5 mg/dL (95% CI, 1.0-4.1), whereas on day 5 the difference was 5.3 mg/dL (95% CI, 3.3-7.5), with a significant increase of 2.8 mg/dL (95% CI, 0.2-5.5). On postoperative day 7 the difference was 11.4 mg/dL (95% CI, 8.2-14.6), with an increase of 6.1 mg/dL (95% CI, 2.2-9.9) from day 5. The mean CRP level in the group with complications showed an increase of 1.2 mg/dL (95% CI, -1.3 to 3.8) from day 3 to day 5 and of 6.2 mg/dL (95% CI, 2.6-9.8) from day 5 to day 7. The optimal cutoff for the CRP level in predicting early postoperative complications was 3.1 mg/dL on postoperative day 3 and 5.2 mg/dL on postoperative day 5, with a sensitivity of 87.5% (95% CI, 52.9-97.8) and 80% (95% CI, 37.6-96.4), a specificity of 62.5% (95% CI, 52.1-71.9) and 91.2% (95% CI, 81.1-96.2), a positive predictive value of 17.5% (95% CI, 8.7-31.9) and 44.4% (95% CI, 18.9-73.3), a negative predictive value of 98.2% (95% CI, 90.6-99.7) and 98.1% (95% CI, 90.1-99.7), and an area under the receiver operating characteristic curve of 75.0% (95% CI, 61.9-80.1) and 85.6% (95% CI, 74.1-96.5), respectively. CONCLUSION: CRP on postoperative day 5 seemed to be a moderately accurate predictive marker of early postoperative complications in the patients who had undergone elective laparoscopic shaving for rectosigmoid DIE.
