Training in Diagnostic Hysteroscopy: The "Arbor Vitae" Method

The use of oral nomegestrol acetate/estradiol in rapid and random start preparation of endometrium before office hysteroscopic polypectomies: A multicenter, prospective, randomized controlled trial

OBJECTIVE

To evaluate the use of oral nomegestrol acetate/estradiol in random start rapid preparation of endometrium before office hysteroscopic polypectomy.

STUDY DESIGN

Multicenter, prospective, randomized controlled trial.

SETTING

University hospitals.

PARTICIPANTS

80 adult women undergoing office hysteroscopic polypectomy between January 2023 and March 2024 were randomized to intervention (n = 40) or control (n = 40). Exclusion criteria included the presence of endouterine pathology other than endometrial polyps solely.

METHODS

Subjects in the intervention group were treated with oral nomegestrol acetate/estradiol 1.5 mg/2.5 mg/day started taking the drug from an indefinite time in the menstrual cycle (random start) for 14 days. Subjects in the control group did not receive any pharmaceutical treatment and underwent polypectomy between days 8 and 11 of the menstrual cycle.

RESULTS

On the day of the procedure, the difference in pre- and post-office hysteroscopic polypectomy endometrial ultrasound thickness was statistically significant between the two groups, with endometrial thickness in both measurements being thinner for the intervention group (p < 0.001). In the nomegestrol acetate/estradiol-treated group, compared with the control, there was also a statistically significant difference in the physician's assessment of the quality of endometrial preparation (p < 0.001), the quality of visualization of the uterine cavity (p < 0.001), and satisfaction with the performance of the procedure (p < 0.001). Finally, all surgical outcomes analyzed were better in the treatment group.

CONCLUSION

Treatment with nomegestrol acetate/estradiol could provide rapid, satisfactory and low-cost preparation of the endometrium before office polypectomy, thus improving surgical performance and woman's compliance.

Evaluation of the benefit of indocyanine green as an educational and practical tool for ureteral identification in laparoscopic pelvic surgery: a cross-sectional study

BACKGROUND

Indocyanine green (ICG) is a visible near-infrared fluorescent dye. Several studies have reported its benefit in identifying important anatomical structures, tissue vascularization, and sentinel lymph nodes in the case of tumors. Studies have shown that ICG is critical and safe in gynecologic surgeries. However, research on how ICG dye can help surgeons in laparoscopic surgeries correctly identify the course of the ureter has yet to be further investigated.

METHOD

This cross-sectional study enrolled 62 gynecology attending and resident surgeons who were asked to identify the course of the ureter on images of laparoscopic surgeries. The results were then compared with images in which ICG dye highlighted the course of the ureter. The purpose of this study was to detect the ability of surgical assistants and residents to adequately identify the course of the ureter in laparoscopic pelvic surgeries.

RESULTS

No statistically significant differences were found in terms of year of residency, years of experience, number of laparoscopic procedures attended, and correct identification of ureter course. ICG proved useful in identifying the correct ureteral trajectory.

CONCLUSIONS

ICG can be a valuable tool to improve the correct identification of ureters and improve surgical outcomes.

Characteristics of hysteroscopic training models: A review of the literature

Objectives

The purpose of this review is to summarize the characteristics and applications of current hysteroscopic training models.

Methods

We conducted a systematic search of PubMed, Embase, and Cochrane Library for eligible studies published before March 2024. Manual screening of references and citation tracking were also performed.

Results

Reported hysteroscopic training models included virtual reality simulators, non-biological material models, plant tissue models, animal tissue models, and human tissue models. No training model was distinctly superior in terms of realism, haptic feedback, availability of standardized scoring of operations, preparation difficulty, reusability of surgical procedure, and prices. Utilizing any type of models for hysteroscopy simulation training could assist trainees in enhancing relevant knowledge, skills, self-confidence, and comfort, but virtual reality models had an advantage in training capacity.

Conclusions

Each hysteroscopic training model has its advantages and disadvantages. An appropriate training curriculum is needed to efficiently leverage the merits of different models. The realism and training effectiveness of various training models need to be compared using rigorously designed studies and standard evaluation tools.

Reproductive Outcomes in Young Women with Early-Stage Cervical Cancer Greater than 2 cm Undergoing Fertility-Sparing Treatment: A Systematic Review

Background and Objectives: Despite advancements in detection and treatment, cervical cancer remains a significant health concern, particularly among young women of reproductive age. Limited data exists in the literature regarding fertility-sparing treatment (FST) of cervical cancers with tumor sizes greater than 2 cm. The objective of this systematic review was to evaluate the reproductive outcomes of women diagnosed with cervical cancer greater than 2 cm who underwent FST. Materials and Methods: A comprehensive search of the literature was carried out on the following databases: MEDLINE, EMBASE, Global Health, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), the Health Technology Assessment Database, and Web of Science. Only original studies (retrospective or prospective) that reported reproductive outcomes of patients with cervical cancer >2 cm were considered eligible for inclusion in this systematic review (CRD42024521964). Studies describing only the oncologic outcomes, involving FST for cervical cancers less than 2 cm in size, and case reports were excluded. Results: Seventeen papers that met the abovementioned inclusion criteria were included in the present systematic review. In total, 443 patients with a cervical cancer larger than 2 cm were included in this systematic review. Eighty pregnancies occurred, with 24 miscarriages and 54 live births. Conclusions: FST appears to be a viable option for women of childbearing age diagnosed with cervical cancer larger than 2 cm. However, careful consideration is advised in interpreting these encouraging results, as they are subject to limitations, such as variability in study designs and potential biases. In addition, reproductive outcomes should be further cross-referenced with oncologic outcomes to clarify the potential risk-benefit ratio. It is critical to conduct further research using standardized approaches and larger participant groups to strengthen the validity of the conclusions drawn.

Reproductive and Oncologic Outcomes in Young Women with Stage IA and Grade 2 Endometrial Carcinoma Undergoing Fertility-Sparing Treatment: A Systematic Review

BACKGROUND

Endometrial cancer (EC) is the most common gynecological malignancy in both Europe and the USA. Approximately 3-5% of cases occur in women of reproductive age. Fertility-sparing treatment (FST) options are available, but very limited evidence regarding grade 2 (G2) ECs exists in the current literature. This systematic review aimed to comprehensively evaluate reproductive and oncologic outcomes among young women diagnosed with stage IA or G2EC disease who underwent FST.

METHODS

A comprehensive search of the literature was carried out on the following databases: MEDLINE, EMBASE, Global Health, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), the Health Technology Assessment Database, and Web of Science. Only original studies that reported the oncologic and reproductive outcomes of patients with stage IA and G2EC tumors who underwent FST were considered eligible for inclusion in this systematic review (CRD42023484892). Studies describing only the FST for endometrial hyperplasia or G1 EC were excluded.

RESULTS

Twenty-two papers that met the abovementioned inclusion criteria were included in the present systematic review. Preliminary analysis suggested encouraging oncologic and reproductive outcomes after FST.

CONCLUSIONS

The FST approach may represent a feasible and safe option for women of childbearing age diagnosed with G2EC. Despite these promising findings, cautious interpretation is warranted due to inherent limitations, including heterogeneity in study designs and potential biases. Further research with standardized methodologies and larger sample sizes is imperative for obtaining more robust conclusions.

Use of Diode Laser in Hysteroscopy for the Management of Intrauterine Pathology: A Systematic Review

Background: Hysteroscopy currently represents the gold standard for the diagnosis and treatment of intrauterine pathologies. Recent technological progress has enabled the integration of diagnostic and operative time, leading to the "see and treat" approach. Diode laser technology is emerging as one of the most innovative and intriguing techniques in this context. Methods: A comprehensive search of the literature was carried out on the main databases. Only original studies reporting the treatment of intrauterine pathologies using diode laser were deemed eligible for inclusion in this systematic review (PROSPERO ID: CRD42023485452). Results: Eight studies were included in the qualitative analysis for a total of 474 patients undergoing laser hysteroscopic surgery. Eighty-three patients had female genital tract abnormalities, 63 had submucosal leiomyomas, 327 had endometrial polyps, and one patient had a scar pregnancy. Except for leiomyomas, whose technique already included two surgical times at the beginning, only seven patients required a second surgical step. Cumulative rates of intraoperative and postoperative complications of 2.7% and 0.6%, respectively, were reported. Conclusions: Diode laser through "see and treat" hysteroscopy appears to be a safe and effective method. However, additional studies with larger sample sizes and improved designs are needed to consolidate the evidence currently available in the literature.

Comparison of Secondary Prevention Following Hysteroscopic Adhesiolysis in the Improvement of Reproductive Outcomes: A Retrospective Cohort Study

Intrauterine adhesion (IUA) is primarily caused by endometrial injury, and hysteroscopic adhesiolysis is presently the main treatment. However, postoperative recurrence and poor pregnancy outcomes remain intractable. In this study, we aim to assess the effects of different treatments on clinical symptoms and reproductive outcomes in IUA. This retrospective study was conducted in a tertiary university-affiliated women's hospital. The study included 1449 consecutive women who desired to have a baby and were diagnosed with IUA through hysteroscopy from January 2016 to December 2021. Patients with IUA underwent hysteroscopic electric resection (E) or cold scissors separation (C), as well as hormone therapy and one or both of the following secondary prevention measures: intrauterine devices (IUD) and hyaluronic acid gel (HA). The pregnancy rate (PR) was significantly higher in the E + IUD + HA (90.23% CI: 85.82, 94.64%) than in other groups (p = 0.000) groups. The rates of full-term birth (p = 0.000) and live birth (p = 0.000) were significantly higher in the E + IUD + HA (67.82% and 68.97%, respectively) and E + HA (62.41% and 63.91%, respectively) groups. Multivariate logistic regression analysis revealed a significantly higher PR in women who received second-look hysteroscopy (OR 1.571, 95% CI: 1.009-2.224, p = 0.013) and E + IUD + HA (OR 4.772, 95% CI: 2.534-8.987, p = 0.000). Combining hysteroscopic electric resection with IUDs and HA gel could prevent adhesion recurrence and improve postoperative pregnancy and live birth outcomes in IUA. Furthermore, postoperative second-look hysteroscopy may increase the PR and shorten the waiting period.
