Application of Deep Learning Model in the Sonographic Diagnosis of Uterine Adenomyosis.

BACKGROUND: This study aims to evaluate the diagnostic performance of Deep Learning (DL) machine for the detection of adenomyosis on uterine ultrasonographic images and compare it to intermediate ultrasound skilled trainees. METHODS: Prospective observational study were conducted between 1 and 30 April 2022. Transvaginal ultrasound (TVUS) diagnosis of adenomyosis was investigated by an experienced sonographer on 100 fertile-age patients. Videoclips of the uterine corpus were recorded and sequential ultrasound images were extracted. Intermediate ultrasound-skilled trainees and DL machine were asked to make a diagnosis reviewing uterine images. We evaluated and compared the accuracy, sensitivity, positive predictive value, F1-score, specificity and negative predictive value of the DL model and the trainees for adenomyosis diagnosis. RESULTS: Accuracy of DL and intermediate ultrasound-skilled trainees for the diagnosis of adenomyosis were 0.51 (95% CI, 0.48-0.54) and 0.70 (95% CI, 0.60-0.79), respectively. Sensitivity, specificity and F1-score of DL were 0.43 (95% CI, 0.38-0.48), 0.82 (95% CI, 0.79-0.85) and 0.46 (0.42-0.50), respectively, whereas intermediate ultrasound-skilled trainees had sensitivity of 0.72 (95% CI, 0.52-0.86), specificity of 0.69 (95% CI, 0.58-0.79) and F1-score of 0.55 (95% CI, 0.43-0.66). CONCLUSIONS: In this preliminary study DL model showed a lower accuracy but a higher specificity in diagnosing adenomyosis on ultrasonographic images compared to intermediate-skilled trainees.

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.

Indocyanine Green Fluorescence Angiography after Full-thickness Bowel Resection for Rectosigmoid Endometriosis-A Feasibility Study.

STUDY OBJECTIVE: To evaluate feasibility of near-infrared (NIR)-indocyanine green (ICG) imaging for bowel vascularization assessment after full-thickness bowel resection for rectosigmoid endometriosis (RSE). DESIGN: This is a prospective, single-center, preliminary study on consecutive patients who were symptomatic submitted to discoid or segmental resection for RSE and NIR-ICG evaluation for vascular assessment of the anastomotic line from May 2018 to January 2020. SETTING: Tertiary university hospital. PATIENTS: Thirty-two women with RSE meeting eligibility criteria were included for study analysis. INTERVENTIONS: NIR-ICG evaluation of anastomotic line vascularization after RSE removal. MEASUREMENTS AND MAIN RESULTS: Fluorescence degree of the anastomotic line was assessed with a 0 to 2 Likert scale, as follows: 0 or "absent" (no fluorescence observed), 1 or "irregular" (not uniform distribution or weak fluorescence), and 2 or "regular" (uniform distribution of fluorescence and similar to the proximal colon). In all the patients included in the study (100%), NIR-ICG imaging allowed the evaluation of fluorescence degree of the anastomotic line. No adverse reaction related to ICG use was recorded. The protocol did not greatly lengthen operating time (median, 4 [range, 3-5] minutes). Excellent interoperator agreement was observed. Most of the patients (31 of 32, 96.9%) showed regular fluorescence on the anastomotic line; in 1 patient with irregular fluorescence at NIR-ICG after discoid excision, the anastomotic suture was reinforced through interrupted stitches. We had 1 case of anastomotic leakage after segmental resection with intraoperative good fluorescence at NIR-ICG evaluation. CONCLUSION: NIR-ICG imaging for anastomotic perfusion assessment after discoid or segmental resection for RSE seems to be a feasible, safe, and reproducible method.

Prevalence of adenomyosis in endometrial cancer patients: a systematic review and meta-analysis.

INTRODUCTION: Several studies have assessed the histological co-existence of endometrial carcinoma (EC) and adenomyosis. However, the significance of this association is still unclear. OBJECTIVE: To assess the prevalence of adenomyosis in women with EC for a better understanding of the association between the two diseases. MATERIALS AND METHODS: A systematic review and meta-analysis was performed by searching electronics databases from their inception to March 2020, for all studies that allowed extraction of data about prevalence of adenomyosis in EC patients. Adenomyosis prevalence was calculated for each included study and as pooled estimate, with 95% confidence interval (CI). RESULTS: Eight retrospective cohort studies assessing 5573 EC patients were included in our analysis. Of total, 1322 were patients with adenomyosis, and 4251 were patients without adenomyosis. Pooled prevalence of adenomyosis in EC patients was 22.6% (95% CI 12.7-37.1%). CONCLUSION: Adenomyosis prevalence in EC patients was not different from that reported for other gynecological conditions. The supposed association between the two diseases appears unsupported.

Adenomyosis and endometriosis in adolescents and young women with pelvic pain: prevalence and risk factors.

AIM: To evaluate the prevalence of ultrasound diagnosis of adenomyosis and endometriosis in young women complaining of pelvic pain and to find the symptoms and clinical characteristics associated with these diseases in young women. METHODS: Cross-sectional study, including 100 young women (14-24 years) with a history of chronic pelvic pain. Women were asked detailed medical hystory and pain symptoms scores (Visual Analogue Scale) and underwent gynecological examination and ultrasound evaluation. RESULTS: The prevalence of endometriosis and adenomyosis in young women amounted to 25.0% and 46.0%, respectively. A significant correlation was found between ovarian endometriosis and adenomyosis. Dysmenorrhea and dyspareunia were risk factors for adenomyosis. Dyschezia, dyspareunia, chronic pelvic pain, presence of sonographic soft markers suggestive of pelvic adhesions, being a worker and having a previous surgery were risk factors for endometriosis. Young women (20-24 years) had a higher incidence of both adenomyosis and endometriosis than adolescents (14-19 years). CONCLUSIONS: Our outcomes strengthen the hypothesis of a progressive and common course of the natural history of endometriosis, which initially may manifest with symptoms, then with signs of pelvic adhesions and finally as adenomyosis, ovarian endometriomas or deep infiltrating endometriosis.

Rectosigmoid Endometriosis Vascular Patterns at Intraoperative Indocyanine Green Angiography and their Correlation with Clinicopathological Data.

Introduction. The objective of the study was to evaluate the presence of different rectosigmoid endometriosis (RSE) vascular patterns using intraoperative indocyanine green (ICG) angiography and their correlation with clinicopathological data. Material and Methods. A prospective pilot study on 30 consecutive symptomatic women affected by RSE and scheduled for minimally invasive surgery between May 2018 and January 2019. ICG was used for the intraoperative evaluation of RSE vascularization. Perfusion grade was classified as follows: 0-1 = no or low fluorescence (hypovascular pattern); 2 = regular fluorescence, similar to healthy surrounding rectosigmoid tract (isovascular pattern); and 3-4 = diffuse or abundant fluorescence (hypervascular pattern). Results. Thirty women were intravenously injected with ICG after nodule exposure. No adverse effects related to ICG use were noted. After a 5- to 50-s latency from ICG injection, the real-time direct visualization of RSE perfusion showed diffuse or abundant fluorescence in 12/30 (40%) women, while in the remaining 18/30 (60%), fluorescence was poor or absent. No statistical differences were observed between the 2 groups regarding preoperative, intraoperative, and histological variables analyzed, except for a maximum diameter of bowel lesions and microvessel density (MVD). Hypovascular nodules had a larger maximum diameter (39.5 ± 15.6 mm vs 30.3 ± 11.4 mm, P < .05) and lower MVD (154.6+/43.6 vs 281.1+/-77.4, P < .05) than hypervascular ones. Conclusions. ICG angiography is a feasible and safe technique to intraoperatively assess RSE vascularization. The majority (60%) of endometriotic nodule presented a hypovascular pattern. The hypovascular pattern seems to be associated with a larger nodule size and lower MVD.

Feasibility and safety of two different surgical routes for the eradication of recto-vaginal endometriosis with vaginal mucosa infiltration (Endo-Vag-r study).

INTRODUCTION: Recto-vaginal endometriosis surgical management needing partial colpectomy is a surgically challenging condition and has been associated with a notable risk of major postoperative complications. In the present study we sought to compare feasibility and safety of total laparoscopic (TL) and vaginal-assisted (VA) routes in women affected by symptomatic recto-vaginal endometriosis with vaginal mucosa infiltration scheduled for minimally invasive surgery. MATERIAL AND METHODS: Multi-centric, retrospective cohort study on medical records of consecutive reproductive age women submitted to complete macroscopic eradication of symptomatic recto-vaginal endometriosis with vaginal mucosa infiltration between March 2013 and November 2017. The two groups were compared in terms of preoperative data and surgical outcomes. RESULTS: 84 women were included in the study (TL = 57 and VA = 27). The two groups were comparable in terms of preoperative, surgical and postoperative data. The major postoperative complications rate was 5.3% (3 of 57) in the TL group and 7.4% (2 of 27) in the VA group, without a significant difference. In the TL group we reported one case of bowel anastomosis dehiscence and two cases of pelvic abscess. In the VA group, one case of small bowel perforation after extensive adhesiolysis treated with ileal resection and one case of rectal sub-occlusion after segmental resection and mechanical anastomosis were noticed. CONCLUSIONS: In women affected by recto-vaginal endometriosis with vaginal mucosal infiltration, perioperative outcomes do not seem to be influenced by the surgical route adopted.

Transvaginal Ultrasound and Doppler Features of Intraligamental Myomas.

OBJECTIVES: To describe the ultrasound (US) features of intraligamental myomas (IMs) using Morphological Uterus Sonographic Assessment group standardized terminology. METHODS: This was a retrospective monocentric study. A total of 125 consecutive women with a preoperative US diagnosis of a myoma located close to the uterine isthmus (International Federation of Gynecology and Obstetrics stages 5, 6, and 7) from 2016 to 2019 who underwent laparoscopic or laparotomic myomectomy or hysterectomy were included for study analyses. The US data were retrieved from US reports and stored digital images by 2 authors. Ultrasound features of myomas were described according to Morphological Uterus Sonographic Assessment terminology. Clinical data for the study population were retrieved from the patients' records. RESULTS: Nineteen women with a surgical confirmation of an IM were included in the study group; the remaining population constituted the control group (n = 106). Non-uniform echogenicity was detected in 17 of 19 (89%) of IMs compared to 26 of 106 (25%) fibroids in the control group (P < .001). The presence of shadowing was detected in 12 of 19 (63%) IMs compared to 94 of 106 (89%) cases in the control group (P = .004). Intraligamental myomas were more vascularized tumors compared to myomas in the control group (P = .004). Transvaginal US showed high specificity for the diagnosis of an IM (0.93; 95% confidence interval, 0.87-0.96). CONCLUSIONS: On US imaging, IMs appear as vascularized solid tumors with nonuniform echogenicity; cones of shadows were less frequent in IMs than the control group, and this finding can help in the differential diagnosis. Knowledge of their specific US features could help sonographers make an accurate diagnosis, allowing them to plan correct surgery and avoid severe complications.

Dienogest or Norethindrone acetate for the treatment of ovarian endometriomas: Can we avoid surgery?

OBJECTIVE: To compare the effects of Dienogest (D) and Norethindrone acetate (N) in symptomatic women with ovarian endometriomas, analyzing the efficacy in reducing endometrioma size and symptom relief and drug tolerability. STUDY DESIGN: Retrospective study including 135 symptomatic women with ultrasonographic diagnosis of ovarian endometrioma. Women were divided into two groups: 1) women who received D 2 mg/day (group D); 2) women who received N 2.5 mg/day (group N). Women were evaluated at therapy prescription and after 6 and 12 months of treatment: transvaginal ultrasound was performed to assess the mean diameter of endometriomas, a Visual Analogue Scale was used to rank endometriosis related symptoms (dysmenorrhea, dyspareunia, chronic pelvic pain). The main outcome measure was the comparison between the 2 groups in terms of variations in endometrioma size and endometriosis related symptoms during the follow-up. Drug tolerability was also analyzed in terms of side effects. RESULTS: A reduction in ovarian endometrioma size was observed during treatment in both groups, with no significant differences between groups D and N. Endometriosis related symptoms decreased in both groups, but the decrease was significantly higher in group D than in group N for all symptoms, both at 6 and 12 months of treatment. Regarding drug tolerability, uterine bleeding/spotting and weight gain were reported more frequently by women in the group N than women in the group D, both at 6 and 12 months of treatment. CONCLUSION: Progestin therapy with D or N appears to be effective in reducing the size of endometriomas and related symptoms, with a greater effect on symptoms relief and higher tolerability in women treated with D.
