How to design effective educational videos for teaching evidence-based medicine to undergraduate learners - systematic review with complementing qualitative research to develop a practicable guide

BACKGROUND

eLearning can be an effective tool to achieve learning objectives. It facilitates asynchronous distance learning, increasing flexibility for learners and instructors. In this context, the high educational value of videos provides an invaluable primary component for longitudinal digital curricula, especially for maintaining knowledge on otherwise rarely taught subjects. Although literature concerning eLearning evaluation exists, research comprehensively describing how to design effective educational videos is lacking. In particular, studies on the requirements and design goals of educational videos need to be complemented by qualitative research using grounded theory methodology.

METHODS

Due to the paucity of randomized controlled trials in this area, there is an urgent need to generate recommendations based on a broader fundament than a literature search alone. Thus, the authors have employed grounded theory as a guiding framework, augmented by Mayring's qualitative content analysis and commonly used standards. An adaptive approach was conducted based on a literature search and qualitative semi-structured interviews. Drawing on these results, the authors elaborated a guide for creating effective educational videos.

RESULTS

The authors identified 40 effective or presumedly effective factors fostering the success of video-based eLearning in teaching evidence-based medicine, providing a ready-to-use checklist. The information collected via the interviews supported and enriched much of the advice found in the literature.

DISCUSSION

To the authors' knowledge, this type of comprehensive guide for video-based eLearning needs has not previously been published. The interviews considerably contributed to the results. Due to the grounded theory-based approach, in particular, consensus was achieved without the presence of a formal expert panel. Although the guide was created with a focus on teaching evidence-based medicine, due to the general study selection process and research approach, the recommendations are applicable to a wide range of subjects in medical education where the teaching aim is to impart conceptual knowledge.

Interceed combined with bone marrow mesenchymal stem cells improves endometrial receptivity of intrauterine adhesion

Background

This study aimed to investigate the impact of intrauterine adhesions (IUA) therapy and endometrial receptivity by implanting autologous bone marrow mesenchymal stem cells (BMSCs) into the Interceed and subsequently placing them in the uterine cavity of rats.

Methods

Fifty rats were divided into 5 groups according to the random number table method (10 rats in each group). Following the development of the IUA model through mechanical injury, the animals were categorized into different treatment groups: the IUA model (intrauterine perfusion of saline), Interceed therapy (intrauterine placement of Interceed), BMSCs therapy (intrauterine perfusion of BMSCs), BMSCs + Interceed therapy (intrauterine placement of BMSCs + Interceed), and a control group (intrauterine perfusion of saline). The Hematoxylin-eosin (HE) staining technique was employed to identify and assess the pathological alterations in the endometrium. Additionally, it facilitated the quantification of endometrial glands and the determination of endometrial thickness. Masson staining was used to detect fibrosis in rat uterus. The number of microvascular density (MVD) was detected by immunohistochemistry (IHC). Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blot were used to detect the levels of leukemia inhibitory factor (LIF), integrin ανβ3, and vascular endothelial growth factor (VEGF) in uterine tissue. Male and female rats were combined in cages for reproductive and conception evaluation.

Results

In comparison to the control, the number of endometrial glands in the IUA model was significantly reduced, and the degree of endometrial thinning and fibrosis was significantly increased (p < 0.05). Compared with the IUA model, the number of endometrial glands did not exhibit any significant alterations in endometrial thickness and MVD number. The expressions of LIF, integrin ανβ3, and VEGF in the uterine tissue were not significantly improved with Interceed therapy, resulting in no significant improvement in the pregnancy rate (p > 0.05). The number of endometrial glands, endometrial thickness, and MVD in the BMSCs therapy group were significantly increased. Moreover, the expressions of LIF, integrin ανβ3, and VEGF in uterine tissue exhibited a significant increase, leading to a comparatively higher pregnancy rate (p < 0.05). In the BMSCs + Interceed therapy group, the number of endometrial glands, endometrial thickness, and MVD were significantly increased, and the expressions of LIF, integrin ανβ3, and VEGF in uterine tissue were significantly increased as well, along with a corresponding rise in the pregnancy rate (p < 0.05).

Conclusion

The intrauterine placement of Interceed combined with BMSCs in IUA rats can thicken the damaged endometrium, increase the number of glands, promote endometrial angiogenesis, improve endometrial receptivity, and increase the rate of pregnancy in IUA rats.

Tissue damage between barbed suture and conventional sutures in animal laboratory model using scanning electron microscopy

This study aimed to compare the tissue damage caused by barbed sutures and conventional sutures using scanning electron microscopy (SEM). Porcine myocardium was incised and sutured using different thread types: barbed suture, (STRATAFIX® Spiral PDS PLUS) and conventional sutures, (VICRYL® and PDS Plus®). Needle hole shapes were examined at magnifications of 30×-100×. VICRYL® suture damaged the tissue and created large gaps around the needle holes. The tissue around the needle holes was smoother and less damaged in the single suture ligations with PDS®; however, a large gap had formed. In the continuous suture with STRATAFIX®, the tissue around the needle holes was significantly smoother and minimally damaged, with no noticeable gaps around the needle holes. Barbed sutures reduced the load on needle holes and minimised tissue damage owing to the dispersion of traction forces by the barbs compared with conventional sutures.

Transvaginal ultrasound and magnetic resonance imaging in the diagnosis of endometrioma: a systematic review and meta-analysis of diagnostic test accuracy studies

INTRODUCTION

The diagnosis of endometriomas in patients with endometriosis is of primary importance because it influences the management and prognosis of infertility and pain. Imaging techniques are evolving constantly. This study aimed to systematically assess the diagnostic accuracy of transvaginal ultrasound (TVUS) and magnetic resonance imaging (MRI) in detecting endometrioma using the surgical visualisation of lesions with or without histopathological confirmation as reference standards in patients of reproductive age with suspected endometriosis.

METHODS

PubMed, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature and ClinicalTrials.gov databases were searched from their inception to 12 October 2022, using a manual search for additional articles. Two authors independently performed title, abstract and full-text screening of the identified records, extracted study details and quantitative data and assessed the quality of the studies using the 'Quality Assessment of Diagnostic Accuracy Study 2' tool. Bivariate random-effects models were used to determine the pooled sensitivity and specificity, compare the two imaging modalities and evaluate the sources of heterogeneity.

RESULTS

Sixteen prospective studies (10 assessing TVUS, 4 assessing MRI and 2 assessing both TVUS and MRI) were included, representing 1976 participants. Pooled TVUS and MRI sensitivities for endometrioma were 0.89 (95% confidence interval 'CI', 0.86-0.92) and 0.94 (95% CI, 0.74-0.99), respectively (indirect comparison p-value of 0.47). Pooled TVUS and MRI specificities for endometrioma were 0.95 (95% CI, 0.92-0.97) and 0.94 (95% CI, 0.89-0.97), respectively (indirect comparison p-value of 0.51). These studies had a high or unclear risk of bias. A direct comparison (all participants undergoing TVUS and MRI) of the modalities was available in only two studies.

CONCLUSION

TVUS and MRI have high accuracy for diagnosing endometriomas; however, high-quality studies comparing the two modalities are lacking.

Impact of haemostasis methods during ovarian cystectomy on ovarian reserve: a pairwise and network meta-analysis

BACKGROUND

Haemostasis during ovarian cystectomy is reported to damage the ovarian reserve, but the comparative impacts of three haemostasis methods (bipolar energy, suture and haemostatic sealant) on ovarian reserve in patients with ovarian cysts are not well known.

METHODS

The Cochrane Library, PubMed and Web of Science databases were searched from the date of inception of the database to June 2022 for literature exploring the impact of haemostasis methods during ovarian cystectomy on ovarian reserve. A traditional meta-analysis was performed using Review Manager software. A network meta-analysis (NMA) was performed using Stata and GemTC software.

RESULTS

The direct meta-analysis comparison indicated that the mean postoperative reduction of anti-Müllerian hormone (AMH) level was significantly higher in the electrocoagulation (bipolar) group than suture and haemostatic sealant group, both in the overall group and subgroup of women with ovarian endometrioma. In NMA, the reduction of postoperative AMH levels in the electrocoagulation (bipolar) group was higher than the suture group at 6 months with a statistical significance, and at 1, 3 and 12 months without a significant difference. The difference in the postoperative decrease of AMH level did not reach statistical significance between suture and sealant, coagulation and haemostatic sealant. The comprehensive ranking results revealed that suture treatment was, with the highest probability, beneficial to the protection of the ovarian reserve.

CONCLUSIONS

There was insufficient research to detect the optimal haemostasis method for ovarian reserve preservation in ovarian cystectomy. Nevertheless, haemostasis by electrocoagulation (bipolar) should be avoided when possible, and the suture might be considered as the best choice.

Incorporating low haemoglobin into a risk prediction model for conversion in minimally invasive gynaecologic oncology surgeries

BACKGROUND

A well-known complication of laparoscopic management of gynaecologic masses and cancers is the need to perform an intraoperative conversion to laparotomy. The purpose of this study was to identify novel patient risk factors for conversion from minimally invasive to open surgeries for gynaecologic oncology operations.

METHODS

This was a retrospective cohort study of 1356 patients ≥18 years of age who underwent surgeries for gynaecologic masses or malignancies between February 2015 and May 2020 at a single academic medical centre. Multivariable logistic regression was used to study the effects of older age, higher body mass index (BMI), higher American Society of Anaesthesiologist (ASA) physical status, and lower preoperative haemoglobin (Hb) on odds of converting from minimally invasive to open surgery. Receiver operating characteristic (ROC) curve analysis assessed the discriminatory ability of a risk prediction model for conversion.

RESULTS

A total of 704 planned minimally invasive surgeries were included with an overall conversion rate of 6.1% (43/704). Preoperative Hb was lowest for conversion cases, compared to minimally invasive and open cases (11.6 ± 1.9 vs 12.8 ± 1.5 vs 11.8 ± 1.9 g/dL, p<.001). Patients with preoperative Hb <10 g/dL had an adjusted odds ratio (OR) of 3.94 (CI: 1.65-9.41, p=.002) for conversion while patients with BMI ≥30 kg/m2 had an adjusted OR of 2.86 (CI: 1.50-5.46, p=.001) for conversion. ROC curve analysis using predictive variables of age >50 years, BMI ≥30 kg/m2, ASA physical status >2, and preoperative haemoglobin <10 g/dL resulted in an area under the ROC curve of 0.71. Patients with 2 or more risk factors were at highest risk of requiring an intraoperative conversion (12.0%).

CONCLUSIONS

Lower preoperative haemoglobin is a novel risk factor for conversion from minimally invasive to open gynaecologic oncology surgeries and stratifying patients based on conversion risk may be helpful for preoperative planning.

The oncological and reproductive outcomes of fertility-preserving treatments for stage 1 grade 1 endometrial carcinoma: a systematic review and meta-analysis

INTRODUCTION

The number of patients desiring fertility-preserving treatment for endometrial cancer rather than standard surgical management continues to increase.

OBJECTIVE

We aimed to evaluate the efficacies of fertility-preserving treatments on the live birth rate, remission and relapse rates for women with stage 1a grade 1 endometrial carcinoma to support patient counselling.

METHODS

We performed a meta-analysis for our primary outcomes of overall remission and relapse rate, and for secondary analysis, we divided papers into treatment type: systemic progestins, intrauterine progestins or hysteroscopic resection and adjuvant hormonal treatment.

RESULTS

Thirty-five observational studies met inclusion criteria, with a total of 624 patients. Overall, conservative treatment of endometrial cancer showed a remission rate of 77% (95% CI: 70-84%), a relapse rate of 20% (95% CI: 13-27%) and a live birth rate of 20% (95% CI: 15-25%) with more favourable outcomes for the hysteroscopic resection group.

CONCLUSIONS

Hysteroscopic resection and adjuvant hormonal treatment had the most favourable fertility and oncological outcomes. Further high-quality prospective multi-centre trials are warranted to determine the optimal treatment regimen and dosage and risk stratification for these patients.

Prediction of outcomes after chemoradiotherapy for cervical cancer by neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio

BACKGROUND

Cervical cancer ranks as the second most fatal tumour globally among females. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been widely applied to the diagnosis of cancers.

METHODS

The clinicopathologic data of 180 patients with stage IB2-IIB cervical cancer who underwent radical concurrent chemoradiotherapy from January 2018 to December 2019 were retrospectively analysed. Receiver operating characteristic (ROC) curves were plotted to analyse the optimal cut-off values of NLR and PLR for predicting the therapeutic effects of concurrent chemoradiotherapy. The associations of PLR and other clinicopathological factors with 1-year survival rates were explored through univariate analysis and multivariate Cox regression analysis, respectively.

RESULTS

NLR was significantly associated with the therapeutic effects of neoadjuvant therapy, with the optimal cut-off value of 2.89, area under the ROC curve (AUC) of 0.848 (95% confidence interval [CI]: 0.712-0.896), sensitivity of 0.892 (95% CI: 0.856-0.923) and specificity of 0.564 (95% CI: 0.512-0.592). PLR had a significant association with the therapeutic effects of neoadjuvant therapy, with the optimal cut-off value of 134.27, AUC of 0.766 (95% CI: 0.724-0.861), sensitivity of 0.874 (95% CI: 0.843-0.905) and specificity of 0.534 (95% CI: 0.512-0.556). Lymphatic metastasis ([95% CI: 1.435-5.461], [95% CI: 1.336-4.281], depth of invasion ([95% CI: 1.281-3.546], [95% CI: 1.183-3.359]) and tumour size ([95% CI: 1.129-3.451], [95% CI: 1.129-3.451]) were independent factors influencing the overall survival and disease-free survival (DFS) of patients with cervical cancer. NLR (95%CI: 1.256-4.039) and PLR (95%CI:1.281-3.546) were also independent factors affecting DFS.

CONCLUSION

NLR and PLR in the peripheral blood before treatment may predict DFS of patients with stage IB2-IIB cervical cancer.

Advanced repair of recurrent and low-large hysterotomy defects using a myometrial glide flap

BACKGROUND

The resolution of factors linked to the recurrence of cesarean section defects can be accomplished through a comprehensive technique that effectively addresses the dehiscent area, eliminates associated intraluminal fibrosis, and establishes a vascularized anterior wall by creating a sliding myometrial flap.

OBJECTIVE

Propose a comprehensive surgical repair for recurrent and large low hysterotomy defects in women seeking pregnancy or recurrent spotting.

STUDY DESIGN

A retrospective cohort analysis included 54 patients aged 25-41 with recurrent large cesarean scar defects treated at Otamendi, CEMIC, and Valle de Lili hospitals. Comprehensive surgical repair was performed by suprapubic laparotomy, involving a wide opening of the vesicouterine space, removal of the dehiscent cesarean scar and all intrauterine abnormal fibrous tissues, using a glide myometrial flap, and intramyometrial injection of autologous platelet-rich plasma. Qualitative variables were determined, and descriptive statistics were employed to analyze the data in absolute frequencies or percentages. The data obtained were processed using the InfostatTM statistic program.

RESULTS

Following the repair, all women experienced normal menstrual cycles and demonstrated an adequate lower uterine segment thickness, with no evidence of healing defects. All patients experienced early ambulation and were discharged within 24 h. Uterine hemostasis was achieved at specific points, minimizing the use of electrocautery. The standard duration of the procedure was 60 min (skin-to-skin), and the average bleeding was 80-100 ml. No perioperative complications were recorded. A control T2-weighted MRI was performed six months after surgery. All patients displayed a clean, unobstructed endometrial cavity with a thick anterior wall (Median: 14.98 mm, IQR 13-17). Twelve patients became pregnant again, all delivered by cesarean between 36.1 and 38.0 weeks, with a mean of 37.17 weeks. The thickness of the uterine segment before cesarean ranged between 3 and 7 mm, with a mean of 3.91 mm. No cases of placenta previa, dehiscence, placenta accreta spectrum (PAS), or postpartum hemorrhage were reported.

CONCLUSIONS

The comprehensive repair of recurrent low-large defects offers a holistic solution for addressing recurrent hysterotomy defects. Innovative repair concepts effectively address the wound defect and associated fibrosis, ensuring an appropriate myometrial thickness through a gliding myometrial flap.

A decade of progress: bringing mixed reality image-guided surgery systems in the operating room

Advancements in mixed reality (MR) have led to innovative approaches in image-guided surgery (IGS). In this paper, we provide a comprehensive analysis of the current state of MR in image-guided procedures across various surgical domains. Using the Data Visualization View (DVV) Taxonomy, we analyze the progress made since a 2013 literature review paper on MR IGS systems. In addition to examining the current surgical domains using MR systems, we explore trends in types of MR hardware used, type of data visualized, visualizations of virtual elements, and interaction methods in use. Our analysis also covers the metrics used to evaluate these systems in the operating room (OR), both qualitative and quantitative assessments, and clinical studies that have demonstrated the potential of MR technologies to enhance surgical workflows and outcomes. We also address current challenges and future directions that would further establish the use of MR in IGS.

Prolonged adhesiolysis to pregnancy interval is associated with placenta accreta spectrum in women with intrauterine adhesion

BACKGROUND

Both the trauma of endometrium and hysteroscopic adhesiolysis can lead to a high rate of placenta accreta spectrum (PAS) in women with intrauterine adhesion (IUA). This study analysed the impact of time interval from adhesiolysis to pregnancy on PAS in IUA women.

METHODS

Patients diagnosed with IUA who underwent adhesiolysis in Anhui Women and Children's Medical Centre between January 2016 and December 2020 were included in this case-series study. Clinical data were obtained from electronic medical records and telephone interviews.

RESULTS

Among a total of 102 IUA women with successful pregnancies, 8 (7.8%) suffered from miscarriages with PAS, and 94 (92.2%), 47 with PAS and 47 without PAS, had successful delivery. The total prevalence of PAS in pregnant women with IUA was 53.9% (55/102). The average time from adhesiolysis to pregnancy in the PAS group was significantly longer than in the non-PAS group (14.2 ± 5.7 vs. 10.3 ± 4.4 months, p = 0.000). Regression analysis showed that AFS grade (OR = 7.40, 95% CI 1.38-39.73, p = 0.020) and adhesiolysis to pregnancy interval time between 12 and 24 months (OR = 12.09, 95% CI 3.76-38.83, p = 0.000) were closely related to PAS. A Kaplan-Meier analysis showed the median interval time to PAS was 16.00 months (95% CI 15.11-16.89).

CONCLUSIONS

We assume that prolonged adhesiolysis to pregnancy interval may be considered a significant risk factor for PAS in IUA women.

Characterising umbilical abdominal wall endometriosis as a distinct subgroup of abdominal wall endometriosis - retrospective cohort study

Abdominal wall endometriosis (AWE) is one of the rarest forms of endometriosis. Little is known about differences between umbilical AWE (U-AWE) and non-umbilical AWE (non-U-AWE) patients. This retrospective cohort study included patients treated for AWE at tertiary endometriosis centre between 2012 and 2020. Patients were divided into two groups - umbilical AWE and non-umbilical AWE.We identified 14 U-AWE and 45 non-U-AWE patients who mostly had lesions in caesarean section scar (38, 64.4%), rarely at other locations (7, 11.9%). Infertility rates for U-AWE patients and non-U-AWE patients were 57.1% and 17.8%, respectively. Concurrent or previous peritoneal endometriosis was noted in 85.7% of U-AWE and 24.4% of non-U- AWE patients. In addition, U-AWE patients and non-UAWE patients significantly differed in following: parity, number of previous caesarean sections, lesion size, prevalence of concurrent or previous deep infiltrating endometriosis, bleeding from abdominal wall, cyclic pain, continuous pain.Infertility and pelvic endometriosis were more prevalent in U-AWE patients. Our data suggests that U-AWE may be a specific marker for a patient highly prone to pelvic endometriosis and subsequent infertility. Findings suggests that clinician should consider comprehensive evaluation of U-AWE patients.

The predictors of successful methotrexate treatment of tubal ectopic pregnancy

BACKGROUND

The pre-treatment characteristics of the patient and ectopic pregnancy to determine the patients who are likely to successfully respond to methotrexate (MTX) therapy remain controversial. This study investigated the outcomes of ectopic pregnancy after one and two MTX doses and their independent predictors.

METHODS

Retrospective cross-sectional study of women who consented to MTX treatment in 2017-2018 at our institution (N = 317). Of these, patients with Caesarean scar pregnancies were excluded because they require different treatment protocols (n = 25). All patients were treated according to our institution's protocol based on international guidelines and standardised across the three hospitals included in the current study. We retrieved patients' demographics, laboratory, ultrasonography, and clinical characteristics from our hospital database. Serum β-human chorionic gonadotropin (β-hCG) was measured using electrochemiluminescence immunoassay; ectopic pregnancy was diagnosed using ultrasonography (transvaginal probe).

RESULTS

Two ninety-two patients were included in the current analysis. Age, pre-treatment β-hCG levels, sonographic presence of yolk sac, presence of foetal cardiac activity, and pelvic pain were significantly different between patients with successful and unsuccessful outcomes. Younger age (adjusted odds ratio [aOR] 2.33, 95% confidence interval (CI) 1.16-4.66, p = .017), no pelvic pain (aOR 2.65, 95%CI 1.03-6.83, p = .043), lower initial β-hCG level (aOR 1.32, 95%CI 1.08-1.59, p = .005), and absence of foetal cardiac activity (aOR 12.63; 95% CI 1.04-153.6; p = .047) were independently associated with success. Treatment failure odds were >2 folds higher for each 10-year age increase (p = .017), 32% higher for each 1000 IU/L increase in initial β-hCG level (p = .005), and >2 folds higher in presence of pelvic pain (p = .043).

CONCLUSIONS

MTX is effective in most patients, averting invasive surgery, which might affect fertility. Pre-treatment β-hCG levels, age, pelvic pain, and foetal cardiac activity was independently associated with outcomes. Research should assess the relationship between the ectopic pregnancy size and treatment outcomes and refine β-hCG titres where treatment would be ineffective.

Impact of trainees involvement on surgical outcomes of abdominal and laparoscopic myomectomy

BACKGROUND

To determine the association of trainees involvement with surgical outcomes of abdominal and laparoscopic myomectomy including operative time, rate of transfusion, and complications.

METHODS

A retrospective cohort study of 1145 patients who underwent an abdominal or laparoscopic myomectomy from 2008-2012 using the American College of Surgeons National Surgical Quality Improvement Program database (Canadian Task Force Classification II-2).

RESULTS

Overall, 64% of myomectomies involved trainees. Trainees involvement was associated with a longer operative time for abdominal myomectomies (mean difference 20.17 minutes, 95% Confidence Interval (CI) [11.37,28.97], p < 0.01) overall and when stratified by fibroid burden. For laparoscopic myomectomy, there was no difference in operative time between trainees vs no trainees involvement (mean difference 4.64 minutes, 95% CI [-18.07,27.35], p = 0.67). There was a higher rate of transfusion with trainees involvement for abdominal myomectomies (10% vs 2%, p < 0.01; Odds Ratio (OR) 5.62, 95% CI [2.53,12.51], p < 0.01). Trainees involvement was not found to be associated with rate of transfusion for laparoscopic myomectomy (4% vs 5%, p = 0.86; OR 0.82, 95% CI [0.16,4.14], p = 0.81). For abdominal myomectomy, there was a higher rate of overall complications (15% vs 5%, p < 0.01; OR 2.96, 95% CI [1.77,4.93], p < 0.01) and minor complications (14% vs 4%, p < 0.01; OR 3.71, 95% CI [2.09,6.57], p < 0.01) with no difference in major complications (3% vs 2%, p = 0.23). For laparoscopic myomectomy, there was no difference in overall (6% vs 10% p = 0.41; OR 0.59, 95% CI [0.18,2.01], p = 0.40), major (2% vs 0%, p = 0.38), or minor (5% vs 10%, p = 0.32; OR 0.52, 95% CI [0.15,1.79], p = 0.30) complications.

CONCLUSION

Trainees involvement was associated with increased operative time, rate of transfusion, and complications for abdominal myomectomy, however, did not impact surgical outcomes for laparoscopic myomectomy.

Hysteroscopy needs of indigenous communities in Northern Quebec: a retrospective cohort study

We aimed to determine the surgical output for patients from Nunavik undergoing transfer to an urban centre for hysteroscopy, and associated costs. We performed a retrospective chart review of all patients from the 14 villages of Nunavik transferred for hysteroscopic surgery from 2016 to 2021. Diagnoses, surgical intervention, and nature of the procedure were all extracted from the patient charts, and costs/length of stay obtained from logisticians and administrators servicing the Nunavik region. Over a 5-year period, 22 patients were transferred from Nunavik for hysteroscopy, of which all were elective save one. The most common diagnosis was endometrial or cervical polyp and the most common procedure was diagnostic hysteroscopy. The average cost for patient transfer and lodging to undergo hysteroscopy in Montreal ranged from $6,000 to $15,000 CDN. On average, 4-5 patient transfers occur annually for hysteroscopy, most commonly for management of endometrial polyps, at a cost of $6,000 to $15,000 CDN, suggesting the need to investigate local capacity building in Nunavik and assess cost-effectiveness.

The impact of caesarean scar niche on fertility - a systematic review

BACKGROUND

The trend of increasing caesarean section (CS) rates brings up questions related to subfertility. Research regarding the influence of CS on assisted reproduction techniques (ART) is conflicting. A potential mechanism behind CS-induced subfertility is intra uterine fluid resulting from a caesarean scar defect or niche. The vaginal microbiome has been repeatedly connected to negative ART outcomes, but it is unknown if the microbiome is changed in relation to a niche.

METHODS

This systematic review describes literature investigating the effect of a niche on live birth rates after assisted reproduction. Furthermore, studies investigating a difference in microbial composition in subfertile persons with a niche compared to no niche are evaluated. Pubmed, Embase and Web of Science were searched on March 2023 for comparative studies on both study questions. Inclusion criteria were i.e., English language, human-only studies, availability of the full article and presence of comparative pregnancy data on a niche. The quality of the included studies and their risk of bias were assessed using the Newcastle-Ottawa scale for cohort studies. The results were graphically displayed in a forest plot.

RESULTS

Six retrospective cohort studies could be included on fertility outcomes, with a total of 1083 persons with a niche and 3987 without a niche. The overall direction of effect shows a negative impact of a niche on the live birth rate (pooled aOR 0.58, 95% CI 0.48-0.69) with low-grade evidence. Three studies comparing the microbiome between persons with and without a CS could be identified.

CONCLUSION

There is low-grade evidence to conclude that the presence of a niche reduces live birth rates when compared to persons without a niche. The theory that a caesarean has a negative impact on pregnancy outcomes because of dysbiosis promoted by the niche is interesting, but there is no sufficient literature about this.

Evidence based management of patients with endometriosis undergoing assisted conception: British fertility society policy and practice recommendations

Endometriosis is a chronic inflammatory condition in women of reproductive age, which can lead to infertility and pelvic pain. Endometriosis associated infertility is multifactorial in nature adversely affecting each step of the natural reproductive physiology and thereby processes and outcomes of Assisted Reproductive Technology (ART) cycles. These outcomes are further complicated by the subtype of endometriosis, being peritoneal, deep infiltrating and ovarian, which bear negative effects on ovarian reserve, response to stimulation, accessibility for oocyte retrieval, intraoperative safety and endometrial receptivity. There is still a lack of clear guidance about the role of surgery for ovarian endometriosis/endometriomas. This guideline evaluates the evidence of the impact of pelvic endometriosis and endometriomas on the outcome of ART and provides recommendations for management options before and during ART including intra-uterine insemination. Recommendations are made based on the current evidence for the management of patients with endometriosis across each step of ART with the primary aim of improving ART outcomes.

Factors associated with dysmenorrhoea and menorrhagia improvement in patients with adenomyosis after uterine artery embolisation

BACKGROUND

This study examined the improvement of dysmenorrhoea and menorrhagia after uterine artery embolisation (UAE) in women with symptomatic adenomyosis and identified factors that could predict the improvement of dysmenorrhoea and menorrhagia.

METHODS

This retrospective study included women with adenomyosis who underwent bilateral UAE between December 2014 and December 2016. The percentage of the volume of the absence of contrast enhancement on T1-weighted images was evaluated 5-7 days after UAE. A receiver operating characteristic (ROC) analysis was used to determine a cut-off point and predict the improvement of dysmenorrhoea and menorrhagia.

RESULTS

Forty-eight patients were included. At 24 and 36 months after UAE, the improvement rates for dysmenorrhoea and menorrhagia were 60.4% (29/48) and 85.7% (30/35), and the recurrence rates were 19.4% (7/36) and 9.1% (3/33), respectively. Only the percentage of the volume of the absence of contrast enhancement on T1-weighted images was associated with the improvement of dysmenorrhoea (p = 0.001, OR = 1.051; 95% CI: 1.02-1.08) and menorrhagia (p = 0.006, OR = 1.077; 95% CI: 1.021-1.136). When the cut-off value of the ROC analysis was 73.1%, sensitivity, specificity, positive predictive value, and negative predictive value for the improvement of dysmenorrhoea were 58.6%, 94.7%, 94.4%, and 60%, while they were 58.9%, 80%, 100%, 100%, and 45.5% for the improvement of dysmenorrhoea.

CONCLUSION

Bilateral UAE for symptomatic adenomyosis led to good improvement of dysmenorrhoea and menorrhagia. The percentage of the volume of the absence of contrast enhancement on T1-weighted images of the uterus in postoperative magnetic resonance imaging might be associated with the improvement of dysmenorrhoea and menorrhagia.

It's complicated: The relationship of non-narcotic medications and postoperative opioid use in radical cystectomy patients

INTRODUCTION

The effect of individual non-narcotic analgesics in cystectomy enhanced recovery after surgery (ERAS) is unknown. Additionally, many non-narcotic medications are associated with side effects pertinent to the cystectomy population. To better understand the actual use and utility of these medications, we sought to characterize the association between non-narcotic medications and milligram morphine equivalent (MME) narcotic score during the postoperative inpatient stay.

METHODS

We reviewed 260 consecutive ERAS cystectomy patients. The MME impact of non-narcotic compliance and cumulative dose of medication received was evaluated separately with general linear models. We also assessed relationship of non-narcotic compliance to patient reported pain score, length of stay (LOS), and time to return of bowel function (ROBF) and performed manual review of postoperative documentation to identify reasons for medication noncompliance.

RESULTS

Compliance with postoperative acetaminophen, gabapentin, and ketorolac was low. There was an inverse relationship between ketorolac dose and MME on postoperative day 1 (-0.026 MME/mg; P = 0.004) and postoperative day 2 (-0.33 MME/mg; P < 0.001). Compliance with ketorolac was associated with lower MME on postoperative day 1 (26.1 MME v. 33.6 MME; P = 0.023). There were no such associations identified with gabapentin or acetaminophen. Gabapentin compliance was associated with earlier ROBF (3.7 days v. 4.3 days; P = 0.006). Ketorolac compliance was associated with lower pain score on POD1 (3.25 VAS v. 4.07 VAS; P = 0.019) and POD2 (3.05 VAS v. 3.85 VAS; P = 0.040) There was no association between medication compliance and LOS. The most common reasons identified for non-compliance with gabapentin and ketorolac were renal function concerns (38% and 40% respectively), bleeding concerns with ketorolac (20%) and concerns for neurologic adverse effect with gabapentin (16%).

CONCLUSION

Compliance with non-narcotic medications in our ERAS cystectomy protocol was poor. There was a modest association with ketorolac and postoperative MME but no association with gabapentin or acetaminophen. Further study will clarify the role of these medications for cystectomy patients. Component specific analysis of protocolized care is valuable and may alter care pathways.

Uterine artery pseudoaneurysm caused by hysteroscopic surgery: A case report

BACKGROUND

We report a case of uterine artery pseudoaneurysm (UAP) occurrence during hysteroscopic endometrial polypectomy and its treatment via uterine artery embolization (UAE).

CASE SUMMARY

A 48-year-old primigravid, primiparous patient was incidentally found to have an endometrial polyp during a health checkup, and underwent a hysteroscopic polypectomy at another hospital. Her cervix was dilated with a Laminken-R^® device. After the Laminken-R^® was withdrawn, a large amount of genital bleeding was observed. This bleeding persisted after the hysteroscopic polypectomy, and, as hemostasis became impossible, the patient was transferred to our hospital by ambulance. On arrival, transvaginal ultrasonography revealed a 3-cm hypoechoic mass with a swirling internal pulse on the right side of the uterus, and color Doppler ultrasonography showed feeder vessels penetrating the mass. Pelvic contrast-enhanced computed tomography (CT) confirmed the presence of a mass at this site, and vascular proliferation was observed within the uterine cavity. Consequently, UAP was diagnosed, and UAE was performed. The patient’s postoperative course was uneventful, and 6 mo post-UAE, no recurrence of blood flow to the UAP was observed.

CONCLUSION

When abnormal genital bleeding occurs during hysteroscopic surgery, ultrasonography and contrast-enhanced CT can assist in the detection of early UAPs.

Injectable polyamide-amine dendrimer-crosslinked meloxicam-containing poly-γ-glutamic acid hydrogel for prevention of postoperative tissue adhesion through inhibiting inflammatory responses and balancing the fibrinolytic system

Establishing a physical barrier between the peritoneum and the cecum is an effective method to reduce the risk of postoperative abdominal adhesions. Meloxicam (MX), a nonsteroidal anti-inflammatory drug has also been applied to prevent postoperative adhesions. However, its poor water solubility has led to low bioavailability. Herein, we developed an injectable hydrogel as a barrier and drug carrier for simultaneous postoperative adhesion prevention and treatment. A third-generation polyamide-amine dendrimer (G3) was exploited to dynamically combine with MX to increase the solubility and the bioavailability. The formed G3@MX was further used to crosslink with poly-γ-glutamic acid (γ-PGA) to prepare a hydrogel (GP@MX hydrogel) through the amide bonding. In vitro and in vivo experiments evidenced that the hydrogel had good biosafety and biodegradability. More importantly, the prepared hydrogel could control the release of MX, and the released MX is able to inhibit inflammatory responses and balance the fibrinolytic system in the injury tissues in vivo. The tunable rheological and mechanical properties (compressive moduli: from ∼ 57.31 kPa to ∼ 98.68 kPa;) and high anti-oxidant capacity (total free radical scavenging rate of ∼ 94.56 %), in conjunction with their syringeability and biocompatibility, indicate possible opportunities for the development of advanced hydrogels for postoperative tissue adhesions management.

Laparoscopy combined with hysteroscopy in the treatment of Robert’s uterus accompanied by adenomyosis: A case report

BACKGROUND

Gynaecologists should be aware of a rare obstructive Mullerian duct abnormality like Robert’s uterus and perform further surgery when necessary.

CASE SUMMARY

We report a 41-year-old mother of two children with Robert’s uterus who was examined and treated by laparoscopy and hysteroscopy. Unlike the existing cases reported in the literature, this patient had a late onset of Robert’s uterus symptoms. Due to right tubal ectopic pregnancy 3 years previously, the patient was treated with right salpingectomy and left tubal ligation but suffered aggravated left lower abdominal pain. She was examined and treated by laparoscopy and hysteroscopy, and is completely asymptomatic at 5-year follow-up.

CONCLUSION

The typical obstructive Mullerian abnormality requires further surgery. Combined laparoscopy and hysteroscopy is an effective, minimally invasive technique with better recovery outcomes than traditional transabdominal procedures.

Perioperative adverse events in adult patients with obstructive sleep apnea undergoing ambulatory surgery: An updated systematic review and meta-analysis

BACKGROUND

The suitability of ambulatory surgery for patients with obstructive sleep apnea (OSA) remains controversial. This systematic review and meta-analysis aimed to evaluate the odds of perioperative adverse events in patients with OSA undergoing ambulatory surgery, compared to patients without OSA.

METHODS

Four electronic databases were searched for studies published between January 1, 2011 and July 11, 2023. The inclusion criteria were: adult patients with diagnosed or high-risk of OSA undergoing ambulatory surgery; perioperative adverse events; control group included; general and/or regional anesthesia; and publication on/after February 1, 2011. We calculated effect sizes as odds ratios using a random effects model, and additional sensitivity analyses were conducted.

RESULTS

Seventeen studies (375,389 patients) were included. OSA was associated with an increased odds of same-day admission amongst all surgery types (OR 1.94, 95% CI 1.46-2.59, I2:79%, P < 0.00001, 11 studies, n = 347,342), as well as when only orthopedic surgery was considered (OR 2.68, 95% CI 2.05-3.48, I2:41%, P < 0.00001, 6 studies, n = 132,473). Three studies reported that OSA was strongly associated with prolonged post anesthesia care unit (PACU) length of stay (LOS), while one study reported that the association was not statistically significant. In addition, four studies reported that OSA was associated with postoperative respiratory depression/hypoxia, with one large study on shoulder arthroscopy reporting an almost 5-fold increased odds of pulmonary compromise, 5-fold of myocardial infarction, 3-fold of acute renal failure, and 5-fold of intensive care unit (ICU) admission.

CONCLUSIONS

Ambulatory surgical patients with OSA had almost two-fold higher odds of same-day admission compared to non-OSA patients. Multiple large studies also reported an association of OSA with prolonged PACU LOS, respiratory complications, and/or ICU admission. Clinicians should screen preoperatively for OSA, optimize comorbidities, adhere to clinical algorithm-based management perioperatively, and maintain a high degree of vigilance in the postoperative period.

Understanding the patient experience in nonsurgical management of endometrial cancer and complex atypical hyperplasia due to obesity: A qualitative analysis

Objectives

Patients with class 3 obesity (BMI ≥ 40) and significant medical comorbidities with complex atypical hyperplasia (CAH) and early-stage endometrial cancer (EC) present challenges in standard surgical management. Progestin therapy is an alternative used for patient-centered reasons, including the desire for uterine preservation or because surgery is not a safe option. Our objective was to gain insights into the patient experience when undergoing this treatment approach.

Methods

We identified and recruited patients who received oral or IUD progesterone in the last 5 years for EC or CAH. We conducted semi-structured phone interviews regarding patients' experience with non-surgical management as well as decision-making factors to start progesterone and weight loss. Interviews were audio-recorded and transcriptions were analyzed for common themes.

Results

A total of 20 interviews were performed. We enrolled nine patients with CAH, eight with grade 1 EC, and three with grade 2 EC. The majority of patients (18/20) were managed with IUD. We identified the following 5 common themes support in diagnostic workup and long-term outcomes, autonomy in care, thoroughness in counseling, emotional impact of diagnosis, and perception of obesity as a defining identity.

Conclusion

The themes identified in the present study highlight the challenges and the stigma these patients face. It also demonstrates areas of opportunity in their counseling and care, which will help to build a more effective therapeutic relationship and ultimately lead to greater adherence in care.

Cutting-edge care: unleashing artificial intelligence's potential in gynecologic surgery

PURPOSE OF REVIEW

Artificial intelligence (AI) is now integrated in our daily life. It has also been incorporated in medicine with algorithms to diagnose, recommend treatment options, and estimate prognosis.

RECENT FINDINGS

AI in surgery differs from virtual AI used for clinical application. Physical AI in the form of computer vision and augmented reality is used to improve surgeon's skills, performance, and patient outcomes.

SUMMARY

Several applications of AI and augmented reality are utilized in gynecologic surgery. AI's potential use can be found in all phases of surgery: preoperatively, intra-operatively, and postoperatively. Its current benefits are for improving accuracy, surgeon's precision, and reducing complications.

Ergonomic considerations for unique surgeon populations

PURPOSE OF REVIEW

Surgeons are rapidly diversifying as a population, introducing new ergonomic challenges. This review describes the challenges that are experienced by special populations of surgeons including small-handed surgeons, pregnant surgeons, and trainees, and evidence-based solutions to overcome them.

RECENT FINDINGS

Small-handed and female surgeons report more musculoskeletal complaints compared with their male counterparts. Pregnant surgeons frequently report development or worsening of musculoskeletal disorders such as carpal tunnel syndrome and low back pain. Trainees also report high rates of musculoskeletal complaints with minimal autonomy to alter their environment. Limited objective data exists regarding the ideal instruments currently available for special populations. Several small, randomized studies have proposed exercise regimens targeting the upper extremities and pregnancy-related pain syndromes with improvements in symptoms. Various methods of ergonomic education have been studied in trainees with improvements in operating room posture and performance.

SUMMARY

Limited objective data is available to recommend specific surgical instruments for high-risk surgeon populations. Beneficial exercise regimens have been described for musculoskeletal disorders commonly plaguing surgeons but have yet to be studied explicitly in small-handed or pregnant surgeons and trainees.

Risks and benefits of sentinel lymph node evaluation in the management of endometrial intraepithelial neoplasia

INTRODUCTION

Endometroid intraepithelial neoplasia (EIN) is a premalignant lesion to endometrial cancer. Increasing number of gynecologic oncologists are performing sentinel lymph node (SLN) evaluation during hysterectomy for EIN to ensure complete staging if there is cancer on the final specimen. However, there are no clear guidelines and the benefits and risks to performing SLN evaluation for EIN patients are unclear.

AREAS COVERED

This narrative review examines the advantages and disadvantages of SLN evaluation for EIN patients and provides an algorithm to assist clinicians in selectively applying the procedure for maximal patient benefit. Relevant articles up to March 2024 were obtained from a PubMed search on SLN use with endometrial pathology.

EXPERT OPINION

Sentinel lymph node evaluation for patients with EIN is safe, feasible, and particularly important for the approximately 10% of patients with high-risk endometrial carcinoma on final pathology. However, as most diagnosed carcinomas are low-risk, SLN evaluation would have limited oncologic benefit. While SLN assessment may overtreat most patients with EIN, a significant minority of patients will be improperly staged. We propose an algorithm highlighting the importance of maximal preoperative endometrial sampling and stratifying patients via risk factors to selectively identify those who would benefit most from SLN evaluation.

Efficacy, safety, and feasibility of the treatment of intrauterine pathologies with the mini-resectoscope: A systematic review

BACKGROUND

Hysteroscopy represents the gold standard for the diagnosis and treatment of intrauterine pathologies. The advent of the mini-resectoscope heralded a new era in intrauterine surgery, both in inpatient and outpatient settings.

OBJECTIVES

To evaluate the effectiveness, safety, and feasibility of the mini-resectoscope for the treatment of intrauterine pathologies.

SEARCH STRATEGY

Electronic databases were searched for English-language trials describing surgical procedures for uterine pathologies performed with a mini-resectoscope until 30 April 2023.

SELECTION CRITERIA

Retrospective or prospective original studies reporting the treatment of uterine pathologies with mini-resectoscope were deemed eligible for the inclusion.

DATA COLLECTION AND ANALYSIS

Data about study features, characteristics of included populations, surgical procedures, complications, and results/outcomes were collected.

RESULTS

Seven papers that met the inclusion criteria were included in this systematic review. Quantitative analysis was not possible due to data heterogeneity. A descriptive synthesis of the results was provided accordingly to the pathology hysteroscopically removed/corrected: polyps and myomas, uterine septum, intrauterine synechiae, and isthmocele.

CONCLUSIONS

The mini-resectoscope is poised to play a leading role in hysteroscopic surgery for many pathologies, both in inpatient and outpatient settings. Since some applications of the mini-resectoscope have not yet been thoroughly investigated, future studies should address current knowledge gaps, designing high-quality comparative trials on specific applications.

The relationship between serum levels of epidermal growth factor and β-human chorionic gonadotropin and the type and prognosis of ectopic pregnancy

PURPOSE

This work aimed to explore the relationship between epidermal growth factor (EGF) and β-human chorionic gonadotropin (β-HCG) and ectopic pregnancy types and impact on prognosis.

METHODS

Twenty women with normal pregnancies (NPs) were recruited as control group, and twenty women each with tubal pregnancy (TP) and cervical pregnancy (CP) were recruited. Blood samples were collected to detect EGF and β-HCG. Data on length of hospital stay and incidence of complications were collected. The differences in serum EGF and β-HCG levels were compared among groups and within various types of ectopic pregnancy using analysis of variance and Pearson correlation analysis.

RESULTS

Serum EGF and β-HCG were notably lower in TP and CP group vs. controls (P < 0.05). In subgroup analysis within the types of ectopic pregnancy, serum EGF levels were drastically higher in TP group vs. CP group (P < 0.05). Serum EGF levels were negatively correlated with pregnancy outcomes and incidence of complications (P < 0.05). In patients with TP and CP, serum EGF and β-HCG recovery time and hospital stay differed drastically (P < 0.05). Serum EGF and β-HCG levels showed optimal cutoff values identified at 2.65 μg/L and 11,745.35 IU/L, respectively. The corresponding area under the curve (AUC) values were 0.885 and 0.841.

CONCLUSION

Elevated levels of EGF may be associated with the occurrence of ectopic pregnancy and may impact the type of ectopic pregnancy, pregnancy outcomes, and the incidence of complications. Further clinical research is warranted to investigate these findings.

Factors Associated With Isolated Fallopian Tube Torsion in Pediatric Patients

BACKGROUND

Isolated fallopian tube torsion (IFTT) is a rare form of adnexal torsion that is more difficult to diagnose, which may lead to delays in treatment. Our objectives were to identify clinical and radiologic factors associated with surgically-confirmed IFTT and compare them with those of patients without torsion and with adnexal torsion (AT) in a large pediatric population.

METHODS

We conducted a retrospective chart review of all patients who underwent surgery for suspected adnexal torsion from 2016 to 2019. Torsion was determined intraoperatively, with IFFT defined as those with only tubal but no ovarian torsion and AT defined as those with ovarian torsion, with or without involvement of the ipsilateral fallopian tube. Clinical and radiologic variables were compared between patients with IFTT and those without torsion and with AT using descriptive statistics. A previously-described composite score to predict torsion based on the presence of vomiting and adnexal volume (VVCS) was calculated for each patient.

RESULTS

Of 291 patients who underwent surgery for suspected torsion, 168 had confirmed torsion: 33 (19.6%) IFTT and 135 (80.4%) AT. Patients with IFTT were more likely to be younger (12.8 vs. 14.2 years, P = 0.02), premenarchal (29.0% vs. 10.7%, P = 0.009), experience nausea (90.6% vs. 70.9%, P = 0.02) and vomiting (81.3% vs. 32.8%, P < 0.001), have a paratubal cyst on imaging (18.8% vs. 2.5%, P = 0.003), and have larger adnexal volume (143.3 vs. 64.9 ml, P < 0.001) than those without torsion. Higher BMI (26.6 vs. 22.9 kg/m2, P = 0.03), a paratubal cyst on imaging (18.8% vs. 1.5%, P < 0.001), presence of arterial (65.5% vs. 44.1%, P = 0.04) and venous Doppler flow (79.3% vs. 55.9%, P = 0.02), and radiologic impression indicating lack of torsion (37.9% vs. 16.8%, P = 0.04) were more common in IFTT than AT. The accuracy of the VVCS in predicting torsion for the IFFT group was 83.9%.

CONCLUSIONS

IFTT has a similar clinical presentation to AT but with a higher likelihood of a paratubal cyst and preserved Doppler flow on imaging. IFTT should be strongly considered in patients who present with pain, nausea, and vomiting and have an adnexal mass separate from the ovary on imaging, regardless of Doppler flow.

Pregnancy with endometriosis: Assessment of national-level trends, characteristics, and maternal morbidity at delivery

OBJECTIVE

To examine pregnancy characteristics and maternal morbidity at delivery among pregnant patients with a diagnosis of endometriosis.

STUDY DESIGN

This cross-sectional study queried the Healthcare Cost and Utilization Project's National Inpatient Sample. Study population was 17,796,365 hospital deliveries from 2016 to 2020, excluded adenomyosis and uterine myoma. The exposure was endometriosis diagnosis. Main outcome measures were clinical and pregnancy characteristics and severe maternal morbidity at delivery related to endometriosis, assessed with multivariable regression model.

RESULTS

Endometriosis was diagnosed in 17,590 patients. The prevalence of endometriosis increased by 24 % from one in 1,191 patients in 2016 to one in 853 patients in 2020 (adjusted-odds ratio [aOR] 1.24, 95% confidence interval [CI] 1.19-1.30). Clinical and pregnancy characteristics that had greater than two-fold association to endometriosis included polycystic ovary syndrome, placenta previa, cesarean delivery, maternal age of ≥30 years, prior pregnancy loss, and anxiety disorder. Pregnant patients with endometriosis were more likely to have the diagnosis of measured severe maternal morbidity during the index hospitalization for delivery (47.8 vs 17.3 per 1,000 deliveries, aOR 1.91, 95%CI 1.78-2.06); these associations were more prominent following vaginal (aOR 2.82, 95%CI 2.41-3.30) compared to cesarean (aOR 1.85, 95%CI 1.71-2.00) deliveries. Among the individual morbidity indicators, endometriosis was most strongly associated with thromboembolism (aOR 5.05, 95%CI 3.70-6.91), followed by sepsis (aOR 2.39, 95%CI 1.85-3.09) and hysterectomy (aOR 2.18, 95%CI 1.85-2.56). When stratified for endometriosis anatomical site, odds of thromboembolism was increased in endometriosis at distant site (aOR 9.10, 95%CI 3.76-22.02) and adnexa (aOR 7.37, 95%CI 4.43-12.28); odds of sepsis was most increased in endometriosis at multi-classifier locations (aOR 7.33, 95%CI 2.93-18.31) followed by pelvic peritoneum (aOR 5.54, 95%CI 2.95-10.40); and odds of hysterectomy exceeded three-fold in endometriosis at adnexa (aOR 3.00, 95%CI 2.30-3.90), distant site (aOR 5.36, 95%CI 3.48-8.24), and multi-classifier location (aOR 4.46, 95%CI 2.11-9.41).

CONCLUSION

The results of this nationwide analysis suggest that pregnancy with endometriosis is uncommon but gradually increasing over time in the United States. The data also suggest that endometriosis during pregnancy is associated with increased risk of severe maternal morbidity at delivery, especially for thromboembolism, sepsis, and hysterectomy. These morbidity risks differed by the anatomical location of endometriosis.

Three-Dimensional Printing in Surgical Education: An Updated Systematic Review of the Literature

INTRODUCTION

Three-dimensional printing (3DP) is being integrated into surgical practice at a significant pace, from preprocedural planning to procedure simulation. 3DP is especially useful in surgical education, where printed models are highly accurate and customizable. The aim of this study was to evaluate how 3DP is being integrated most recently into surgical residency training.

METHODS

We performed a structured literature search of the OVID/MEDLINE, EMBASE, and PUBMED databases following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Articles published from 2016 to 2023 that met predefined inclusion and exclusion criteria were included. Data extracted included surgical subspecialty using 3DP, application of 3DP, and any reported satisfaction measures of trainees. A thorough analysis of pooled data was performed to evaluate satisfaction rates among studies.

RESULTS

A total of 85 studies were included. The median number of participants was 18 (interquartile range 10-27). Fourteen surgical disciplines were represented, with ear, nose, and throat/otolaryngology having the highest recorded utilization of 3DP models among residents and medical students (22.0%), followed by neurosurgery (14.0%) and urology (12.0%). 3DP models were created most frequently to model soft tissue (35.3%), bone (24.7%), vessel (14.1%), mixed (16.4%), or whole organs (6.66%) (Fig.1). Feedback from trainees was overwhelmingly positive regarding the fidelity of the models and their support for integration into their training programs. Among trainees, the combined satisfaction rate with their use in the curriculum was 95% (95% confidence interval, 0.92-0.97), and the satisfaction rate with the model fidelity was 90% (95% confidence interval, 0.86-0.94).

CONCLUSIONS

There is wide variation in the surgical specialties utilizing 3DP models in training. These models are effective in increasing trainee comfort with both common and rare scenarios and are associated with a high degree of resident support and satisfaction. Plastic surgery programs may benefit from the integration of this technology, potentially strengthening future surgical curricula. Objective evaluations of their pedagogic effects on residents are areas of future research.

Violence in the healthcare workplace

PURPOSE OF REVIEW

Healthcare workers experience a disproportionate frequency of workplace violence. Identifying commonalities among incidents of workplace violence provides an opportunity for change to prevent and mitigate future violence.

RECENT FINDINGS

Despite a continued decline in overall workplace violence, the rate of violence in the healthcare sector is steadily rising. While healthcare workers make up 13% of the workforce, they experience 60% of all workplace assaults. Environmental, structural, and staffing issues may all contribute to the increased rates of workplace violence affecting healthcare workers.

SUMMARY

Comprehensive proactive workplace violence prevention programs can significantly reduce the frequency of violence and the negative impact on employees and institutions. Analyzing the factors that contribute to violence in the healthcare workplace provides the potential to mitigate these risks and reduce episodes of violence.

Treatment of uterine artery (pseudo)aneurysm during pregnancy: A case report and review of the literature

PURPOSE

To describe the management of uterine artery (pseudo)aneurysm, ruptured or unruptured, during pregnancy.

METHODS

After reporting a case about this rare pathology, a review of the literature was performed. The search was applied to PubMed databases.

RESULTS

A total of eighteen articles met the inclusion criteria. Eighteen patients were reported. Eight (44.4 %) patients didn't have prior medical or surgical history. Fifteen (83.3 %) beneficed interventional radiology method during pregnancy including two cases (13.3 %) with repeated embolization because of recanalization of the (pseudo)aneurysm. Nine patients (50 %) beneficed a planned cesarean between 34 and 39 weeks of gestation. One (15.8 %) patient was diagnosed with fetal death before treatment of the uterine artery (pseudo)aneurysm.

CONCLUSION

The decision to proceed to the treatment of the (pseudo)aneurysm must consider several factors, associated or not with a good fetal vitality and a hemodynamically stable patient. Embolization appears to be the method of choice. Mode of delivery and term remain not clear and contraindication of expulsive efforts in case of a uterine artery (pseudo)aneurysm merit further investigations.

Ovarian Tissue Collection for Fertility Preservation in Children: The Need for Standardised Surgical Practice Guidance

BACKGROUND

Chemotherapy, pelvic radiotherapy (including total body irradiation) and novel compounds used to treat children and teenagers with benign or malignant diseases can lead to impaired fertility. For prepubertal female patients at high risk of treatment-related infertility, upfront storage of ovarian tissue is increasingly being recognised as standard of care. No surgical guidelines exist to ensure best practice technique. We reviewed current UK practice to assess surgical management.

METHODS

A ten-item, anonymous multiple-choice survey was distributed to the lead surgeons in all paediatric centres in England/Wales undertaking ovarian procurement for cryopreservation.

RESULTS

There are currently 18 centres in England and Wales that provide ovarian procurement for cryopreservation. Responses were received from 100% of the invited paediatric surgical oncology centres in England and Wales. 39.3% of participants stated that in their centre <10 cases of ovarian harvest are performed annually. In 32.1% of centres >20 cases are undertaken per year. In 64% of centres surgery is performed by a paediatric surgeon with interest in oncology or fertility preservation. The majority of cases were performed by a Consultant or Senior Registrar (89%). Regarding the surgical technique, 82% of respondents stated they gain access to the abdominal cavity using standard 3-port laparoscopy, 7% use single-port laparoscopy. Most frequently used energy devices for ovary/ovarian tissue resection were Ligasure™ (44%) and Harmonic Scalpel™ (18.5%). 96% of respondents perform a total oophorectomy, 1 respondent stated they perform a hemi-oophorectomy. 53% stated they place the ovary into a retrieval bag only if the ovary was too big for easy removal via the camera port, 28.5% always place it in a retrieval bag. Most surgeons use the umbilical port site for retrieval (82%).

CONCLUSION

This national survey shows significant heterogeneity in the surgical management of ovarian procurement for cryopreservation. To ensure best outcomes, research into the various surgical methods is necessary to provide data for a standardised best practice approach.

LEVEL OF EVIDENCE

This is a level II evidence study. In itself, it is a national survey of specialists, which was undertaken in a prospective manner.

Sexual quality of life and postoperative deep dyspareunia after vNOTES benign adnexal procedures

OBJECTIVE

This study aimed to investigate the impact of vNOTES on postoperative sexual dysfunction in patients undergoing adnexal procedures.

METHODS

We analyzed data from patients who underwent vNOTES adnexal surgeries for benign conditions between May 2020 and May 2023. The primary outcome was the presence of new postoperative deep dyspareunia (DD) or other sexual dysfunctions, which were assessed through a phone survey conducted 6 to 24 months after surgery. Secondary outcomes included surgical feasibility, operative times, complications rate, and postoperative pain evaluation.

RESULTS

We included 103 patients for primary and secondary outcomes and 111 patients for secondary outcomes analysis only. Newly postoperative DD was reported by three patients (2.9%), remained present at 12 postoperative months in one case (1.0%), and spontaneously disappeared in two cases (1.9%) after four and 10 postoperative months, respectively. In the remaining 100 patients (97.1%), no new DD or other sexual function disorders were reported after surgery. vNOTES procedures were successfully performed in all cases, with a mean operative time of 38.2 ± 19.6 min and a conversion rate to conventional laparoscopy of 0.9%. No significant complication was observed.

CONCLUSION

This study suggests a very limited risk of developing postoperative sexual dysfunction after vNOTES benign adnexal procedures.

Opportunistic salpingectomy at the time of vaginal hysterectomy: A systematic review and meta-analysis

BACKGROUND

Despite the rising rates of opportunistic salpingectomy at the time of surgery for non-malignant conditions, salpingectomy is not widely adopted during vaginal hysterectomy (VH) and has not been extensively investigated.

OBJECTIVES

The aim of the primary study was to determine the feasibility of bilateral opportunistic salpingectomy at the time of VH. Secondary aims included surgical outcomes, factors associated with patient selection, and the prevalence of incidental tubal malignancies.

SEARCH STRATEGY

In this systematic review and meta-analysis we searched Pubmed, Embase and ClinicalTrials.gov databases from inception to September 1, 2023, using relevant keywords.

SELECTION CRITERIA

Original articles with no language restriction reporting outcomes of women undergoing planned VH with opportunistic salpingectomy, were considered eligible. Studies including patients undergoing VH with and without opportunistic salpingectomy were also included.

DATA COLLECTION AND ANALYSIS

The Newcastle-Ottawa scale was used to assess quality of observational studies. DerSimonian-Laird random effects meta-analysis was performed and pooled effect estimates and proportions with corresponding 95% confidence intervals were computed. Heterogeneity was assessed using the I2 statistic.

RESULTS

Seven observational cohort studies including 4808 women undergoing opportunistic salpingectomy at the time of VH and 10 295 patients undergoing VH alone were selected. The pooled proportion of success was 81.83 per 100 observations (95% CI: 75.35-87.54). Opportunistic salpingectomy at the time of VH, when feasible, was associated with a significant reduction in intraoperative complications (OR 0.06, 95% CI: 0.01, -0.37, P = 0.03) and total operative time (95% CI: -17.80, -1.07, P = 0.03) compared to those where it failed. Successful salpingectomy was significantly hindered by nulliparity (OR 0.12, 95% CI: -17.69, -1.21, P < 0.001) and favored by pelvic organ prolapse (OR 3.20, 95% CI: 1.35, 7.55, P = 0.008). Immunohistochemical tubal abnormalities were found in 13/579 (2.1%) patients. The overall quality of the evidence, according to the GRADE assessment, was low.

CONCLUSION

Opportunistic salpingectomy is safe, effective, and feasible at the time of VH. Nulliparity and pelvic organ prolapse are factors potentially influencing surgical outcomes.

Evaluation of urological and gynecological surgeons as force multipliers for mass casualty trauma care

BACKGROUND

The clinical demands of mass casualty events strain even the most well-equipped trauma centers and are especially challenging in resource-limited rural, remote, or austere environments. Gynecologists and urologists care for patients with pelvic and abdominal injuries, but the extent to which they are able to serve as "force multipliers" for trauma care is unclear. This study examined the abilities of urologists and gynecologists to perform 32 trauma procedures after mentored training by expert trauma educators to inform the potential for these specialists to independently care for trauma patients.

METHODS

Urological (6), gynecological surgeons (6), senior (postgraduate year 5) general surgery residents (6), and non-trauma-trained general surgeons (8) completed a rigorous trauma training program (Advanced Surgical Skills Exposure in Trauma Plus). All participants were assessed in their trauma knowledge and surgical abilities performing 32 trauma procedures before/after mentored training by expert trauma surgeons. Performance benchmarks were set for knowledge (80%) and independent accurate completion of all procedural components within a realistic time window (90%).

RESULTS

General surgery participants demonstrated greater trauma knowledge than gynecologists and urologists; however, none of the specialties reached the 80% benchmark. Before training, general surgery, and urology participants outperformed gynecologists for overall procedural abilities. After training, only general surgeons met the 90% benchmark. Post hoc analysis revealed no differences between the groups performing most pelvic and abdominal procedures; however, knowledge associated with decision making and judgment in the provision of trauma care was significantly below the benchmark for gynecologists and urologists, even after training.

CONCLUSION

For physiologically stable patients with traumatic injuries to the abdomen, pelvis, or retroperitoneum, these specialists might be able to provide appropriate care; however, they would best benefit trauma patients in the capacity of highly skilled assisting surgeons to trauma specialists. These specialists should not be considered for solo resuscitative surgical care.

Perioperative urinary ketosis and metabolic acidosis in patients fasted for undergoing gynecologic surgery

BACKGROUND

Our bodies have adaptive mechanisms to fasting, in which glycogen stored in the liver and muscle protein are broken down, but also lipid mobilisation is triggered. As a result, glycerol and fatty acids are released into the bloodstream, increasing the production of ketone bodies in liver. However, there are limited studies on the incidence of perioperative urinary ketosis, the intraoperative blood glucose changes and metabolic acidosis after fasting for surgery in non-diabetic adult patients.

METHODS

We conducted a retrospective cohort study involving 1831 patients undergoing gynecologic surgery under general anesthesia from January to December 2022. Ketosis was assessed using a postoperative urine test, while blood glucose levels and acid-base status were collected from intraoperative arterial blood gas analyses.

RESULTS

Of 1535 patients who underwent postoperative urinalysis, 912 (59.4%) patients had ketonuria. Patients with ketonuria were younger, had lower body mass index, and had fewer comorbidities than those without ketonuria. After adjustments, younger age, higher body mass index and surgery starting late afternoon were significant risk factors for postoperative ketonuria. Of the 929 patients assessed with intraoperative arterial blood gas analyses, 29.0% showed metabolic acidosis. Multivariable logistic regression revealed that perioperative ketonuria and prolonged surgery significantly increased the risk for moderate-to-severe metabolic acidosis.

CONCLUSION

Perioperative urinary ketosis and intraoperative metabolic acidosis are common in patients undergoing gynecologic surgery, even with short-term preoperative fasting. The risks are notably higher in younger patients with lower body mass index. Optimization of preoperative fasting strategies including implementation of oral carbohydrate loading should be considered for reducing perioperative metabolic derangement due to ketosis.

Application of a Malecot drain in the management of a vaginal cuff dehiscence: A case report and review of the literature

Background

Vaginal cuff dehiscence (VCD) in the setting of acute infection is an uncommon but serious complication of total hysterectomy without clear guidelines for management. There is a need for further documentation of best practices around treatment, particularly when it comes to surgical drain utilization and placement.

Case description

We present a case of a 68-year-old with primary peritoneal carcinoma who underwent a robot-assisted total laparoscopic hysterectomy as part of an interval debulking surgery and had a VCD. The cuff was repaired vaginally in the operating room with placement of a Malecot catheter for pelvic abscess drainage.

Discussion

The literature is sparse in regard to clear guidelines for management of VCD. Surgical and expectant management approaches are dependent on patient stability, surgical experience, local practice norms, and evidence of intra-abdominal injury. Interventional radiology has become a primary source of drain placement in management of VCD and vaginal cuff abscess. Malecot drains are a low cost, and effective intervention for such management and an important resource for the gynecologic surgeon.

Beyond vulvodynia: from a correct diagnosis to a multidisciplinary care program. A referral center experience

BACKGROUND

Vulvodynia is a chronic pain condition without an identifiable cause. As such, it is a diagnosis of exclusion, and all other causes of vulvar pain should be excluded. Although a standard treatment for vulvodynia has not been established yet, multidisciplinary care programs appear to be effective.

PUROPOSE

The aim of this retrospective monocentric study was to analyze the prevalence of vulvodynia among women referred to our institution for a suspected diagnosis and to evaluate the efficacy of a multidimensional treatment plan. The primary outcome was the prevalence of vulvodynia following differential diagnosis. Secondary outcomes included: prevalence of the differential diagnoses, symptom resolution rate following treatment, and the relation between persistence of symptoms and (a) patients' age; (b) coexisting chronic overlapping pain conditions (COPCs).

RESULTS

After having ruled out all other causes of vulvar pain, only 40.1% of women were considered as affected by vulvodynia. The most frequent differential diagnoses included lower genital tract infections (25.3%), vulvar lichen sclerosus (17.6%) and vulvovaginal atrophy (8.2%). Following a multidisciplinary care program, resolution of symptoms was observed in 13.6% cases, improvement in 64.3% and persistence in 21.9%. We did not find a statistically significant association between persistence of symptoms and age > 38 years (OR 2.10; p = 0.30). Women with one or more COPCs other than vulvodynia had a 75% increased risk of not obtaining a resolution of symptoms (OR 1.75; p = 0.44).

CONCLUSION

A thorough differential diagnosis and a multidisciplinary care program may represent a first way out of the muddle in the management of these patients.

Evaluating the effect of preoperative interventions on sleep health in the perioperative period: a systematic review

Surgery and general anaesthesia have deleterious effects on sleep and disrupted perioperative sleep health is a risk factor for poor surgical outcomes. The objective of this systematic review was to summarise preoperative interventions that report sleep outcomes. Studies that delivered an intervention initiated >24 h prior to surgery among an adult sample without a diagnosed sleep disorder were included. Studies were excluded if they were preclinical or were not published in English. MEDLINE, MEDLINE ePubs Ahead of Print and In-process Citations, Embase, Cochrane Central Register of Controlled Trials, APA PsycINFO, CINAHL, and the Web of Science were searched on February 2, 2023. This review was reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses and was registered with the International Prospective Register of Systematic Reviews (identifier: CRD42021260578). Risk of bias was assessed using the Cochrane Risk-of Bias 2 tool for randomised trials and the Risk Of Bias In Non-randomised Studies - of Interventions for non-randomised trials. Certainty of findings were assessed using the Grading of Recommendations, Assessment, Development and Evaluation framework. The searching yielded 10,938 total citations, and after screening resulted in 28 randomised and 19 non-randomised trials (47 total) with 4937 participants. Sleep was a primary outcome in 16 trials; a sleep outcome was significantly improved relative to comparator in 23 trials. This review demonstrates that preoperative sleep is modifiable via a variety of interventions, including pharmacological, non-pharmacological, and nursing interventions delivered preoperatively or perioperatively. Our results should be considered with caution due to an overall intermediate to high risk of bias in the included trials, and low to very low certainty of evidence. This review supports the modifiability of sleep health among surgical patients and provides the groundwork for preoperative sleep optimisation research.

Laparoscopic surgery for endometrial cancer is oncologically safe and improves hospital stay duration: a retrospective single-center study over a 16-year period

OBJECTIVE

To investigate changes in surgical procedures and patient outcomes of patients diagnosed with endometrial cancer (EC) at a German university hospital between 1998 and 2014.

METHODS

A monocentric, retrospective review was conducted to identify patients diagnosed and treated with EC during the aforementioned period at the Department of Gynecology and Obstetrics at the University Hospital Kiel, Germany.

RESULTS

303 patients were identified. Patient demographics, risk factors, histological subtypes and stages of EC remained consistent over time. The most common surgical procedure was total abdominal hysterectomy (TAH) (81.9%). In 2011, the institution carried out its first total laparoscopic hysterectomy (TLH) for EC, resulting in a significant increase in laparoscopic surgical procedures (2011-2014: N = 70; TAH 44.2%; TLH 51.4%). Although the total number of lymph node stagings remained consistent over time, there was a significant increase in the performance of simultaneous pelvic and para-aortic lymphonodectomy (LNE) compared to pelvic LNE alone (2.6 in 2001-2005 vs. 18.0% in 2011-2014, p ≤ 0.001). The duration of hospital stays significantly decreased over time, with a mean of 20.9 days in the first and 8.5 days in the last period. When comparing surgical procedures, TLHs resulted in significantly shorter postoperative stays with an average of 6.58 vs. 13.92 days for TAH. The surgical procedure performed did not affect 5-year overall survival rates in this study (84.9% for TAH and 85.3% for TLH, p = 0.85).

CONCLUSIONS

Our retrospective single-center study demonstrates that laparoscopic surgery for endometrial cancer is oncologically safe and shortens hospital stays.

Predicting Endometrial Hyperplasia and Endometrial Cancer on Recurrent Abnormal Uterine Bleeding

OBJECTIVE

To develop predictive models for endometrial hyperplasia and endometrial cancer in patients with recurrent abnormal uterine bleeding (AUB).

METHODS

This retrospective cohort study analyzed patients with recurrent AUB who had previous endometrial sampling that showed benign results between January 2013 and December 2021. A model was constructed from the significant factors associated with endometrial hyperplasia and endometrial cancer using multivariate logistic regression. Risk scores were calculated from the log odds of each significant predictive factor and were subsequently subcategorized into risk groups. The overall performance and internal validation of the model were assessed with the area under the receiver operating characteristic curve (AUC) and bootstrap methods.

RESULTS

Of the total 456 patients with recurrent AUB, endometrial hyperplasia and endometrial cancer were detected in 8.3% and 2.2% of cases, respectively. The average interval between the first and second endometrial samplings was 25.1 months. Factors significantly associated with endometrial hyperplasia and endometrial cancer included age older than 45 years (odds ratio [OR] 2.86, 95% CI, 1.31-7.03), nulliparity (OR 3.50, 95% CI, 1.76-6.85), a history of endometrial polyp (OR 3.69, 95% CI, 1.93-7.05), and an interval of less than 12 months between sampling (OR 2.36, 95% CI, 1.25-4.42). Predictive factors were scored and categorized into three groups: 0-3, 5-8, and 9-11 points. The corresponding risks for endometrial hyperplasia and endometrial cancer in these groups were 4.7%, 15.5%, and 57.1%, respectively. The AUC was 73.1%, with a mean absolute error of 0.01.

CONCLUSION

Endometrial hyperplasia and endometrial cancer occur at low incidence among one-fifth of patients with AUB who experience recurrent bleeding. Older age, nulliparity, a history of endometrial polyps, and an interval of less than 12 months between samplings are predictive factors for endometrial hyperplasia and endometrial cancer in this cohort.

A rare case of spontaneous rupture of the uterine artery

Spontaneous rupture of the uterine artery is extremely rare in nonpregnant women, and bleeding can be rapidly controlled by laparoscopy.

Fertility preservation in hematological cancer patients

Among adolescents and young adults, hematological malignancies are the most common malignancies. Although the survival rate of hematological malignancies in young patients has been dramatically improved, due to the continuous improvement and development of tumor diagnosis and treatment options, cytotoxic therapies can significantly reduce a patient's reproductive capacity and cause irreversible infertility. The most two established solutions are embryo cryopreservation and oocyte cryopreservation which can be considered in single female. Sperm or testicular tissue cryopreservation in adult male are feasible approaches that must be considered before gonadotoxic therapy. A comprehensive consultation with reproductive specialists when once diagnosed is a significantly issue which would help those survivors who want to have children. In this article, we review germ cell toxicity, which happens during the treatment of hematological malignancies, and aims to propose safety, efficacy fertility preservation methods in younger patients with hematological malignancies.

Barbed Versus Nonbarbed Suture for Posterior Colporrhaphy: A Randomized Controlled Trial

IMPORTANCE

There is limited literature or even consensus on the suture material used for posterior vaginal repairs.

OBJECTIVES

This study aimed to compare outcomes of barbed versus nonbarbed delayed absorbable suture used for posterior colporrhaphy.

STUDY DESIGN

This study conducted a randomized controlled trial of 72 women undergoing posterior repair using standardized technique-concurrent procedures permitted with barbed (n = 36) or nonbarbed (n = 36) suture. Standardized examinations, validated questionnaires, and a visual analog scale (VAS) were completed at baseline, 6 weeks, and 12 months, and a telephone interview was conducted at 6 months. The primary outcome was posterior compartment pain at 6 weeks, measured by a VAS.

RESULTS

Seventy-two women enrolled, with follow-up rates 6 weeks (100%), 6 months (90.3%), and 12 months (73.6%). Demographics were similar between groups. A VAS with movement was not different between groups at 6 weeks. The odds of experiencing vaginal pain, having myofascial pain on examination, or being sexually active postoperatively were not different between the groups. There were no differences in the length of posterior colporrhaphy, surgical times, or hospital length of stay between the groups. Suture passes were lower in the nonbarbed group (median, 4 vs 7; P = <0.001), and suture burden was higher in the nonbarbed group (median, 26.9 vs 10.5 cm; P = <0.001). There was overall improvement in Pelvic Floor Distress Inventory Short Form 20 prolapse and colorectal subscores but no differences between groups. Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire Short Form 12 scores improved, and dyspareunia decreased at 6 and 12 months in both groups. In addition, there were few anatomic recurrences at 6 weeks (0%) and 12 months (3.4%) and few adverse events.

CONCLUSIONS

This study found no differences in primary or secondary outcomes; however, both suture types resulted in clinical improvements in quality-of-life measures and sexual function.

Laparoscopic Uterine Preservation and Vaginal Reconstruction in a 13-Year-Old Girl with Uterus Didelphys, Bilateral Vesicovaginal Fistulas, and Transverse Vaginal Septum

BACKGROUND

Complex female genital tract malformations account for 1.2% of all female genitourinary malformations. Although exceedingly rare, they can cause severe gynecologic symptoms in young women and lead to fertility problems.

CASE

We present the case of a 13-year-old girl with primary amenorrhea referred for cyclic abdominal lower pain and menouria. Detailed diagnostics revealed uterus didelphys, transverse vaginal septum, and bilateral vesicovaginal fistulas. Laparoscopic left hemi-hysterectomy and salpingectomy were performed. The vesicovaginal fistula on the right side was excised, and the proximal vagina was anastomosed with the distal dimple. Since the operation, the patient has been pain-free and menstruating regularly from the right uterus.

SUMMARY AND CONCLUSION

Preservation of the uterus should be considered in any case of complex female genital tract malformation and, as successful laparoscopic treatment advocates, a minimally invasive approach is feasible.

Preterm birth and uterine fibroid necrosis: The clinical presentation illustrated in a case series

OBJECTIVE

Uterine fibroids increase the risk of preterm birth. The current study highlights uterine fibroid necrosis as a possible cause of (extreme) preterm birth.

STUDY DESIGN

Retrospective cohort study in one Dutch academic hospital. Cases were selected from the 526 participants of the MyoFert study (Netherlands Trial Register, NL7990), which included patients who presented between 2004 and 2018 and were between the age of 18 and 45 years at the time of diagnosis of uterine fibroids. Of these participants, 414 women became pregnant. A retrospective chart review of the first pregnancies was performed. The main outcomes were (imminent) preterm birth and signs of fibroid necrosis on ultrasound. In women with signs of fibroid necrosis, the following data were collected systematically: fibroid characteristics, clinical presentation, pregnancy outcome, and postpartum period.

RESULTS

In total, 66 women had a preterm birth (16 %, 66/414), of which 25 pregnancies ended between 16 and <24 weeks (38 %, 25/66) and 41 pregnancies ended between 24 and <37 weeks of gestation (62 %, 41/66). Of all women with preterm birth and available ultrasound images, 15 % (7/48) had fibroid necrosis at the time of labour. These seven patients, supplemented with three patients with fibroid necrosis during their first pregnancy and at least one episode of imminent preterm birth, are described in more detail. In these ten patients, the fibroids increased substantially in size during the first and second trimester, leading to severe abdominal pain in all patients and hospital admission in seven patients. Ultrasound examination of the fibroids showed heterogenic changes and focal transonic areas in the fibroid, which are characteristics that indicate fibroid necrosis. In four patients, myomectomy was performed and necrosis was confirmed histologically.

CONCLUSION

Fibroid necrosis during pregnancy is likely associated with (imminent) preterm birth. Clinicians are advised to structurally evaluate the myometrium in pregnancy, specifically in women presenting with abdominal pain in the second trimester.
