Endometrial Cancer in a Patient With Didelphys Uterus and a History of Renal Cancer: A Case Report and Literature Review

Müllerian duct anomalies (MDAs) concurrent with endometrial cancer are exceptionally rare, with only a few documented cases. Here, we present a case of endometrial cancer in both horns of a didelphys uterus in a 54-year-old woman with a history of renal cancer, who underwent left radical nephrectomy and left salpingo-oophorectomy. The patient sought medical evaluation due to postmenopausal vaginal bleeding. Hysteroscopy with dilation and curettage revealed the presence of two cervixes and two endometrial cavities, with pathology results indicating endometrioid adenocarcinoma (G1). Preoperative MRI staging confirmed the diagnosis of a double cervix and uterus. Subsequently, an open abdominal hysterectomy and a right salpingo-oophorectomy were performed, revealing a didelphys uterus (International Federation of Gynaecology and Obstetrics 2018, stage IA). This manuscript aims to explore the potential correlation between renal and endometrial malignancies in the presence of MDAs.

Air Embolism: A Rare Lethal Complication of Hysteroscopy in a Young Woman Undergoing Infertility Workup

Compared to operative hysteroscopy, diagnostic hysteroscopy rarely leads to issues. However, one very uncommon yet potentially fatal complication is air embolism, with an incidence rate of three in 17,000 cases. This report describes an unexpected complication discovered during diagnostic hysteroscopy surgery. In the course of routine infertility testing, a 29-year-old woman underwent a diagnostic hysteroscopy under general anesthesia. Intraoperatively, her end-tidal carbon dioxide (EtCO2) levels decreased, oxygen saturation dropped, and heart rate increased, leading the anesthesiologists and critical care team to terminate the procedure and manage her further. Subsequent transesophageal echocardiography confirmed the diagnosis of air embolism. She was managed with 100% oxygen and inotropes and cardiopulmonary resuscitation but despite aggressive medical interventions, her condition did not improve, and she unfortunately passed away. To diagnose, prevent, and manage the potentially devastating consequences associated with diagnostic hysteroscopy, gynecologists and surgical teams must maintain vigilance. The focus should be on proper patient selection, optimal surgical techniques, and the use of high-quality equipment to mitigate the risk of air embolism.

Training in Diagnostic Hysteroscopy: The "Arbor Vitae" Method

Background and Objectives: Diagnostic hysteroscopy is the gold standard in the diagnosis of intrauterine pathology and is becoming an essential tool in the daily practice of gynecology. Training programs for physicians are necessary to ensure adequate preparation and learning curve before approaching patients. The aim of this study was to describe the "Arbor Vitae" method for training in diagnostic hysteroscopy and to test its impact on the knowledge and skills of trainees using a customized questionnaire. Materials and Methods: A three-day hysteroscopy workshop combining theory and practical "hands on "sessions with dry and wet labs has been described. The aim of the course is to teach indications, instruments, the basic principles of the technique by which the procedure should be performed, and how to recognize and manage the pathologies that can be identified by diagnostic hysteroscopy. To test this training method and its impact on the knowledge and skills of the trainees, a customized 10-question questionnaire was administered before and after the course. Results: The questionnaire was administered to 34 participants. All trainees completed the questionnaire, and no missing responses were recorded. Regarding the characteristics of the participants, 76.5% had less than 1 year of experience in performing diagnostic hysteroscopy and 55.9% reported performing fewer than 15 procedures in their career. For 9 of the 10 questions embedded in the questionnaire, there was a significant improvement in the scores between pre- and post-course, demonstrating a perceived significant improvement in theoretical/practical skills by the trainees. Conclusions: The Arbor Vitae training model is a realistic and effective way to improve the theoretical and practical skills required to perform correct diagnostic hysteroscopy. This training model has great potential for novice practitioners to achieve an adequate level of proficiency before performing diagnostic hysteroscopy on live patients.

Limitations of imaging screening tests in the detection of incomplete uterine septum or arcuate uterine anomaly

OBJECTIVES

To determine the detection rates of hysterosalpingogram (HSG), transvaginal 2D ultrasound (TV 2D US), transvaginal 3D ultrasound (TV 3D US) in diagnosing of incomplete uterine septum (IUS) and significant arcuate uterine anomaly (AUA).

METHODS

This retrospective cohort study included patients with infertility or recurrent pregnancy loss (516) that were found to have IUS (317) or significant AUA (199) on diagnostic hysteroscopy (DHS). We compared the detection rate of the various radiological tests in all patients with documented IUS or AUA on DHS.

RESULTS

The diagnosis of IUS and AUA was made in 49.7% on HSG, 54.2% on TV 2D US and 69.5% on TV 3D US. When both HSG and TV 2D US or HSG and TV3D US were used, the diagnosis was correct in 67.7% and 82.6% of patients, respectively.

CONCLUSION

Although HSG, TV 2D US, TV 3D US are useful in the screening for IUS/AUA, none of these imaging tests alone or in combination are accurate enough to rule out the diagnosis of such congenital uterine anomalies. In patients with a history of infertility or RPL and negative radiologic tests, DHS is the only reliable method to rule out IUS or significant AUA.

Diagnostic office hysteroscopy; why is it still painful procedure despite the surgical experience and mini-hysteroscope?

AIM

To evaluate the effect of cervical canal features on pain during outpatient hysteroscopy performed by experienced surgeons using mini-hysteroscope.

METHODS

A prospective observational study was conducted on 303 women undergoing diagnostic hysteroscopy without anesthesia. Pain intensity was evaluated using the visual analog scale (VAS) when the cervical canal was passed. The patients were divided into two groups according to the VAS score: painless or mild pain (VAS <4) and moderate or severe pain (VAS ≥ 4). The relationship between cervical canal characteristics (length, version, and flexion positions, history of cervical intervention, stenosis, synechiae), obstetric and gynecological history, preoperative anxiety level, procedure duration, and pain intensity was examined.

RESULTS

Moderate pain (4 ≤ VAS < 7) was observed in 38% of patients (n = 117) and 14 patients (5%) experienced severe pain (VAS ≥ 7). In multivariate analysis, nulliparity (p = 0.01; OR, 4.6; 95% CI, 1.7-13.2), postmenopausal state (p = 0.02; OR, 2.2; 95% CI, 1.2-4.3), excessive flexion of the cervix and retroverted uterus (p <0.001; OR, 4.1; 95% CI, 2.0-8.5) were identified as risk factors for a painful procedure. Diagnostic hysteroscopy was successful in 98% of the patients. The pain was the primary cause of the failed hysteroscopy.

CONCLUSION

In addition to nulliparity and postmenopausal status, unfavorable features of the cervical canal, such as the excessive flexion position of the cervix and uterine retroversion are significant causes of pain during outpatient hysteroscopy.

Impact of a Province-wide Endometrial Cancer Guideline on Daily Practice

BACKGROUND/AIM

Most women are managed by a general gynaecologist rather than being centralized in an oncogynaecology unit, resulting in different clinical management. In 2006, a hub & spoke model was introduced in the Provincial Healthcare System of Reggio Emilia, and shared guidelines were written. We aimed to verify the adherence to guidelines and the consequent improvements in quality care.

PATIENTS AND METHODS

All patients who underwent a hysterectomy for endometrial cancer in the Reggio Emilia Province hospitals from 2000 to 2016 were included in the study. Clinical and pathological data were carefully recorded for each patient included.

RESULTS

This study included 132 and 277 patients in the periods before and after the implementation of the guideline, respectively. In the post-guideline period, the use of hysteroscopy, magnetic resonance, laparoscopy and adjuvant treatment significantly increased.

CONCLUSION

Common shared guidelines and a clinical audit can help in improving centralization, resulting in an increased quality of care.

Endometrial Cancer Risk Prediction According to Indication of Diagnostic Hysteroscopy in Post-Menopausal Women

We conducted a prospective observational study investigating the clinical relevance of endometrial thickness (ET) and abnormal uterine bleeding (AUB) on endometrial cancer (EC) risk in a cohort of postmenopausal patients undergoing diagnostic hysteroscopy and endometrial biopsy. Patients were divided into two groups according to the indication of diagnostic hysteroscopy: ET_Group (asymptomatic patients with endometrial thickness ≥ 4 mm) and AUB_Group (patients with a history of abnormal uterine bleeding). We further divided the AUB_Group into two subgroups based on endometrial thickness (AUB_Subgroup1: ET < 4 mm; AUB_Subgroup2: ET ≥ 4 mm). The primary outcome was the risk of endometrial cancer and atypical hyperplasia according to the indications of diagnostic hysteroscopy (AUB, ET ≥ 4 mm or both). The secondary outcome was to determine the best cut-off value of endometrial thickness to predict endometrial cancer in asymptomatic postmenopausal women. The prevalence of endometrial cancer and atypical hyperplasia in AUB_Group and ET_Group was 21% and 6.7% respectively. As well as for EC alone, higher prevalence of both conditions was observed in AUB_Subgroup2 (29.3%) in comparison to AUB_Subgroup1 (10.6%; p < 0.001). In asymptomatic patients the cut-off of endometrial thickness that showed the best sensitivity and specificity to diagnose endometrial cancer (100% and 80% respectively) was 11 mm (AUC of 91.4%; Expβ: 1067; CI 95%). In conclusion, considering the high risk of neoplasia, diagnostic hysteroscopy with endometrial biopsy should be mandatory in cases of abnormal uterine bleeding in postmenopausal patients. Moreover, we want to emphasize the need for further evidence stating the clinical relevance of endometrial thickness value in asymptomatic patients and the impact of individual risk factors on endometrial cancer development.

Decreasing Diagnostic Hysteroscopy Performed in the Operating Room: A Quality Improvement Initiative

OBJECTIVES

At our institution, diagnostic hysteroscopy (DH), often combined with uterine curettage, commonly has been performed in the main OR with the patient under general anaesthesia. Our objective was to create targeted interventions aimed at decreasing the number of DHs performed in the OR by 75% over one year.

METHODS

This quality improvement initiative had a quasi-experimental (time-series) design. To obtain baseline numbers of DHs performed each month, we conducted a retrospective chart audit at a university teaching hospital. We implemented the following three groups of interventions: (1) staff education and case review, (2) accessible sonohysterography, and (3) an operative hysteroscopy education program. Procedures were tracked prospectively over a 12-month intervention period and an additional 12-month maintenance period.

RESULTS

One hundred eleven DHs were performed at baseline. During the intervention period, 33 DHs were performed, a 70% reduction from baseline. This resulted in related savings of $126 984 and 12.5 surgical days. In the final quarter of the intervention period, there was an 81% reduction in the number of DHs with adequate preoperative evaluation compared with baseline. Twenty DHs were performed in the maintenance period, an 82% reduction from baseline. The absolute number of complications from DH remained constant during the study period.

CONCLUSION

Carefully planned and targeted interventions to change the culture at our institution decreased the number of DHs performed in the main OR. These initiatives improved patient care, saved costs, and improved OR utilization. Long-term follow-up showed maintenance of the improvements in the year subsequent to the interventions.

Diagnostic hysteroscopy - a retrospective study of 1545 cases

INTRODUCTION

The development of hysteroscopy has provided a minimally invasive approach to common gynecologic problems, such as abnormal uterine bleeding. Diagnostic hysteroscopy is considered now "the gold standard" by the Association of Professors of Gynecology and Obstetrics (2002) in investigation of abnormal uterine bleeding (AUB) in order to rule out organic endouterine causes of AUB. Although the World Health Organization (WHO) recommends hysterosapingography (HSG) alone for management of infertile women many specialists use hysteroscopy as a first-line routine exam for infertility patients regardless of guidelines.

MATERIAL AND METHOD

This paper is a retrospective study of 1545 diagnostic hysteroscopies performed in the "Prof. Dr. Panait Sirbu" Obstetrics and Gynecology Hospital between January 1, 2008 and June 30, 2011. The following parameters were studied: diagnostic hysteroscopy indications, type of anesthesia used, correlation between pre-and postoperative diagnoses.

OUTCOMES

Of 1545 diagnostic hysteroscopies, 78% of cases were performed without anesthesia; of the total of 299 cases of primary infertility diagnostic hysteroscopy showed in 34% of cases tubal obstruction and endouterine pathology; of the total 396 cases of secondary infertility under investigation, diagnostic hysteroscopy showed in 40% of cases tubal obstruction and endouterine pathology; the highest accuracy of HSG was noted for uterine malformation and minimal accuracy was observed for intrauterine adhesions.

CONCLUSIONS

Our experience supports the opinion that diagnostic hysteroscopy should be a first-line routine exam in infertility.Because of the high rate of false positive results for HSG in our study and considering the other studies in specialty literature, we always perform a diagnostic hysteroscopy before Assisted Human Reproduction procedures regardless of the HSG aspect.

Diagnostic hysteroscopy as a primary tool in a basic infertility workup

OBJECTIVE

To assess the value of diagnostic hysteroscopy in a primary workup of infertility.

METHODS

We performed a retrospective analysis (Canadian Task Force Classification II-2) of 221 infertile patients referred to the Outpatient Center for Uterine Cavity Evaluation and the Tel-Aviv University affiliated Assaf Harofe Medical Center for evaluation of the uterine cavity. Patients underwent a diagnostic office hysteroscopy.

RESULTS

Hysteroscopy revealed an abnormal uterine cavity in 30% of women evaluated for either primary or secondary infertility. No significance was found regarding the total number of intrauterine pathologies when comparing the groups of primary versus secondary infertility.

CONCLUSION

Routine diagnostic hysteroscopy should be part of an infertility workup in primary and secondary infertility.
