Preoperative Sonographic Prediction of Limited Axillary Disease in Patients with Primary Breast Cancer Meeting the Z0011 Criteria: an Alternative to Sentinel Node Biopsy?

PURPOSE: To assess the accuracy of preoperative sonographic staging for prediction of limited axillary disease (LAD, one or two metastatic lymph nodes) and to identify factors associated with high prediction-pathology concordance in patients with early-stage breast cancer meeting the Z0011 criteria. MATERIALS AND METHODS: Patients treated between January 2015 and January 2020 were included in this retrospective, multicentric analysis of prospectively acquired service databases. The accuracy of LAD prediction was assessed separately for patients with one and two suspicious lymph nodes on preoperative sonography. Test validity outcomes for LAD prediction were calculated for both groups, and a multivariate model was used to identify factors associated with high accuracy of LAD prediction. RESULTS: Of 2059 enrolled patients, 1513 underwent sentinel node biopsy, 436 primary and 110 secondary axillary dissection. For LAD prediction in patients with one suspicious lymph node on preoperative ultrasound, sensitivity was 92% (95% CI 87-95%), negative predictive value (NPV) was 92% (95% CI 87-95%), and the false-negative rate (FNR) was 8% (95% CI 5-13%). For patients with two preoperatively suspicious nodes, the sensitivity, NPV, and FNR were 89% (95% CI 84-93%), 73% (62-83%), and 11% (95% CI 7-16%), respectively. On multivariate analysis, the number of suspicious lymph nodes was associated inversely with correct LAD prediction ([OR 0.01 (95% CI 0.01-0.93), p ≤ 0.01]. CONCLUSIONS: Sonographic axillary staging in patients with one metastatic lymph node predicted by preoperative ultrasound showed high accuracy and a false-negative rate comparable to sentinel node biopsy for prediction of limited axillary disease.

The Prevalence, Management and Impact of Dysmenorrhea on Medical Students' Lives-A Multicenter Study.

INTRODUCTION: Dysmenorrhea is defined as the presence of painful menstruation, and it affects daily activities in different ways. The aims of this study were to assess the prevalence and management of dysmenorrhea and to determine the impact of dysmenorrhea on the quality of life of medical students. MATERIAL AND METHODS: The study conducted was prospective, analytical and observational and was performed between 7 November 2019 and 30 January 2020 in five university centers from Romania. The data was collected using an original questionnaire regarding menstrual cycles and dysmenorrhea. The information about relationships with family or friends, couples' relationships and university activity helped to assess the effects of dysmenorrhea on quality of life. The level of significance was set at p < 0.05. RESULTS: The study comprised 1720 students in total. The prevalence of dysmenorrhea was 78.4%. During their menstrual period, most female students felt more agitated or nervous (72.7%), more tired (66.9%), as if they had less energy for daily activities (75.9%) and highly stressed (57.9%), with a normal diet being difficult to achieve (30.0%). University courses (49.4%), social life (34.5%), couples' relationships (29.6%), as well as relationships with family (21.4%) and friends (15.4%) were also affected, depending on the duration and intensity of the pain. CONCLUSION: Dysmenorrhea has a high prevalence among medical students and could affect the quality of life of students in several ways. During their menstrual period, most female students feel as if they have less energy for daily activities and exhibit a higher level of stress. The intensity of the symptoms varies considerably and, with it, the degree of discomfort it creates. Most student use both pharmacological and non-pharmacological methods to reduce pain (75.7%). University courses, social life, couples' relationships, as well as relationships with family and friends are affected, depending on the duration and intensity of the pain.

Acute Sheehan's syndrome manifesting initially with diabetes insipidus postpartum: a case report and systematic literature review.

PURPOSE: Acute Sheehan's syndrome is a rare, but potentially life-threatening, obstetric event that can be complicated by diabetes insipidus. Little information on the diagnosis and treatment of Sheehan's syndrome with diabetes insipidus is available. We report on a 28-year-old patient who developed acute Sheehan's syndrome with diabetes insipidus after giving birth, and on a systematic review of similar cases. METHODS: We performed a systematic review of the literature cataloged in PubMed and Google Scholar using the keywords "Sheehan syndrome" OR "Sheehan's syndrome" AND "diabetes insipidus" to identify relevant case reports published between 1990 and 2021. Eight Reports met the inclusion criteria (English-language abstracts available, onset in the puerperium, information about the day of the onset). RESULTS: In the present case, postpartum curettage was necessary to remove the residual placenta. The total amount of blood loss was severe (2500 ml). On the second day postpartal, the patient developed polyuria. Laboratory analysis revealed hypernatremia with increased serum osmolality and decreased urinary osmolality. Hormone analysis showed partial hypopituitarism involving the thyroid, corticotropic, and gonadotropic axes. The prolactin level was elevated. Brain magnetic resonance imaging showed pituitary gland infarction. Desmopressin therapy was initiated and resolved the polyuria. Hormone replacement therapy was administered. Four months later, the patient was well, with partial diabetes insipidus. The literature review indicated that this case was typical in terms of symptoms and disease onset. Most reported cases involve hypotension and peripartum hemorrhage, but some patients without hemorrhage also develop Sheehan's syndrome. Elevated prolactin levels are uncommon and associated with poor prognosis in patients with Sheehan's syndrome. CONCLUSION: Acute Sheehan's syndrome with diabetes insipidus involves nearly all pituitary hormone axes, indicating severe disease. Prolactin elevation could suggest that a case of Sheehan's syndrome is severe.

Evaluation of the SF-36 questionnaire for assessment of the quality of life of endometriosis patients undergoing treatment: A systematic review and meta-analysis.

Endometriosis has a negative influence on the physical, psychological, and social aspects of a patient's life; therefore, it affects the health-related quality of life (HRQoL). The current review aimed to investigate the efficiency of a 36-item generic questionnaire survey (SF-36) for patients with endometriosis who were undergoing medical or surgical treatment. A search strategy including the key words 'endometriosis', 'quality of life' (QOL), and 'questionnaire SF-36' was applied using the PubMed/MEDLINE, EMBASE, and Cochrane databases in order to include articles that evaluated the QOL among women with endometriosis using the SF-36. Only articles that included interviews of patients both before and after surgical or medical endometriosis treatment or those articles that compared study groups were considered. The qualitative analysis was based on 37 articles, whereas the quantitative analysis utilized 14 articles. The research participants included 11,101 women, among whom 6,888 patients were diagnosed with endometriosis. The analysis recorded 17 studies dealing with all types of endometriosis, 9 studies dealing with deep infiltrative endometriosis (DIE), and 9 studies dealing with bowel endometriosis or DIE with bowel involvement. QOL was evaluated using only SF-36 in 12 studies that collectively included 1,912 women and using SF-36 in association with other questionnaires in 25 studies that collectively included 8,022 women. For patients with endometriosis, physical functioning [odds ratio (OR), 78.87; 95% confidence interval (CI), 68.97-88.77; I2=98.77%; P≤0.001] was the most affected life parameter. This parameter showed the highest improvement after surgical intervention (OR, 63.39; 95% CI, 48.71-78.07; I2=97.65%; P≤0.001) or hormonal treatment (OR, 38.65; 95% CI, 14.39-62.91; I2=38.65%; P≤0.001). The 36-item survey generic questionnaire seems to be an efficient tool for assessment of the QOL of life of women with endometriosis who are undergoing surgical or medical treatment. It can be applied before and after the procedure, and it can also be used for comparing study groups.

HPV Status as Prognostic Biomarker in Head and Neck Cancer-Which Method Fits the Best for Outcome Prediction?

The incidence of human papillomavirus (HPV)-related head and neck cancer (HNSCC) is rising globally, presenting challenges for optimized clinical management. To date, it remains unclear which biomarker best reflects HPV-driven carcinogenesis, a process that is associated with better therapeutic response and outcome compared to tobacco/alcohol-induced cancers. Six potential HPV surrogate biomarkers were analyzed using FFPE tissue samples from 153 HNSCC patients (n = 78 oropharyngeal cancer (OPSCC), n = 35 laryngeal cancer, n = 23 hypopharyngeal cancer, n = 17 oral cavity cancer): p16, CyclinD1, pRb, dual immunohistochemical staining of p16 and Ki67, HPV-DNA-PCR, and HPV-DNA-in situ hybridization (ISH). Biomarkers were analyzed for correlation with one another, tumor subsite, and patient survival. P16-IHC alone showed the best performance for discriminating between good (high expression) vs poor outcome (low expression; p = 0.0030) in OPSCC patients. Additionally, HPV-DNA-ISH (p = 0.0039), HPV-DNA-PCR (p = 0.0113), and p16-Ki67 dual stain (p = 0.0047) were significantly associated with prognosis in uni- and multivariable analysis for oropharyngeal cancer. In the non-OPSCC group, however, none of the aforementioned surrogate markers was prognostic. Taken together, P16-IHC as a single biomarker displays the best diagnostic accuracy for prognosis stratification in OPSCC patients with a direct detection of HPV-DNA by PCR or ISH as well as p16-Ki67 dual stain as potential alternatives.

Students' attitudes toward digital learning during the COVID-19 pandemic: a survey conducted following an online course in gynecology and obstetrics.

PURPOSE: The purpose of this survey was to assess medical students' opinions about online learning programs and their preferences for specific teaching formats during COVID 19 pandemic. METHODS: Between May and July 2020, medical students who took an online gynecology and obstetrics course were asked to fill in a questionnaire anonymously. The questionnaire solicited their opinions about the course, the teaching formats used (online lectures, video tutorials featuring real patient scenarios, and online practical skills training), and digital learning in general. RESULTS: Of 103 students, 98 (95%) submitted questionnaires that were included in the analysis. 84 (86%) students had no problem with the online course and 70 (72%) desired more online teaching in the future. 37 (38%) respondents preferred online to traditional lectures. 72 (74%) students missed learning with real patients. All digital teaching formats received good and excellent ratings from > 80% of the students. CONCLUSION: The survey results show medical students' broad acceptance of the online course during COVID 19 pandemic and indicates that digital learning options can partially replace conventional face-to-face teaching. For content taught by lecture, online teaching might be an alternative or complement to traditional education. However, bedside-teaching remains a key pillar of medical education.

Incidence of and risk factors for vaginal cuff dehiscence following total laparoscopic hysterectomy: a monocentric hospital analysis.

PURPOSE: Vaginal cuff dehiscence (VCD) is one of the major surgical complications following hysterectomy with data on incidence rates varying largely and studies assessing risk factors being sparse with contradictive results. The aim of this study was to assess the incidence rate of and risk factors for VCD in a homogenous cohort of women treated for benign uterine pathologies via total laparoscopic hysterectomy (TLH) with standardized follow-up. METHODS: All patients undergoing TLH at the Department of Gynecology and Obstetrics, Saarland University Hospital between November 2010 and February 2019 were retrospectively identified from a prospectively maintained service database. RESULTS: VCD occurred in 18 (2.9%) of 617 patients included. In univariate and multivariate analyses, a lower level of surgeon laparoscopic expertise (odds ratio 3.19, 95% confidence interval (CI) 1.0-9.38; p = 0.03) and lower weight of removed uterus (odds ratio 0.99, 95% CI 0.98-0.99; p = 0.02) were associated positively with the risk of VCD. CONCLUSION: In this homogenous cohort undergoing TLH, laparoscopic expertise and uterine weight influenced the risk of postoperative VCD. These findings might help to further reduce the rate of this complication.

Clinical Data on Immunotherapy in Breast Cancer.

BACKGROUND: Breast cancer has traditionally been considered to have a low immunogenic potential compared to other tumor entities. SUMMARY: The most extensively studied immunotherapeutic agents for breast cancer to date are immune checkpoint inhibitors, with the results of the IMpassion130 trial leading to the approval of atezolizumab plus nab-paclitaxel for first-line treatment of programmed cell death ligand 1-positive, metastatic, triple-negative breast cancer, and studies in earlier stages have yielded promising results. Other immunotherapeutic options being assessed in phases 2 and 3 trials include vaccine-based therapies and treatment with anti-human epidermal growth factor receptor 2 (H-directed immune-linked antibodies) and substances evaluated in early clinical trials as cellular therapies (adoptive cell therapy and chimeric antigen receptor T cells). KEY MESSAGES: Immunotherapy is an emerging modality for the treatment of breast cancer, as evidenced by the plethora of preclinical and clinical concepts and ongoing trials. Early studies established the role of immunotherapeutic agents in the metastatic setting. Ongoing studies will expand our knowledge about the timing of administration, best partners for combination therapy, and predictive biomarkers to guide immunotherapy for breast cancer.

Use of a microsurgical vascular clip system (Yasargil clip) in laparoscopic fibroid enucleation

This video demonstrates the use of a microsurgical temporary vascular clip system to facilitate laparoscopic enucleation of uterine fibroids. Throughout the course of the last three decades, the laparoscopic route has been established as the approach of choice in the surgical treatment of uterine fibroids. Laparoscopic fibroid enucleation is characterized by a low morbidity rate and a high patient satisfaction level. Especially when treating a large fibroid or multiple fibroids, the well-vascularized myometrium can constitute a technical challenge in endoscopic fibroid enucleation. Diffuse bleeding may lead to significant intraoperative hemorrhage. The extensive use of bipolar or monopolar diathermy, in order to achieve hemostasis, might lead to post-operative uterine wall necrosis with a potential risk of uterine rupture during subsequent pregnancies. To address this clinical challenge, we developed a technique with temporary interruption of the uterine blood supply by applying a microsurgical vascular clip (Yasargil vascular clip system, Aesculap, Tuttlingen, Germany) to the uterine artery and the utero-ovarian vessel arcade to minimize bleeding during endoscopic fibroid enucleation.

Significant improvement of laparoscopic knotting time in medical students through manual training with potential cost savings in laparoscopy - an observational study

Objective: Laparoscopy is a standard procedure in operative gynaecology, but laparoscopic simulator training for novices/junior surgeons is not currently well-established. The aims of this study were to demonstrate that a laparoscopic knot course for trainees can significantly shorten the knotting time and to perform a counter-value calculation for the clinic's costs. Material and Methods: An observational study was performed with exercises on a laparoscopic box trainer as part of the practical clerkship in gynaecology and obstetrics between 07.10.2019-31.01.2020. At the beginning and at the end of the exercises, the participants made a laparoscopic knot and the difference in knotting time, Δt in seconds (s) was measured. Results: Eighty-eight medical students needed an average of 247.1 s for the first laparoscopic knot at the beginning of the course and an average of 45.43 s for the second at the end of the course. Mean shortening of the knotting time was 201.67 s or 81.6% (p=0.02). Calculating costs of an average of €40-50 for an operation minute would mean a cost saving of at least €120-150 for a partial node. Conclusion: Trainees can significantly improve their operative skills in a short time with the aid of surgical simulation training. Such training can be beneficial for clinics by reducing the operating time if the basics, such as sewing and instrument guidance, are learned on a simulator. We therefore suggest that operative simulation training should be mandatory in medical education.

Correlation between total sperm count and sperm motility and pregnancy rate in couples undergoing intrauterine insemination.

The frequency and significance of sterility is increasing due to different socio-demographic factors in the industrialized countries. At the same time, the patients' demand for more natural and less invasive fertility treatments is increasing. The most common method used in subfertility is intrauterine insemination (IUI). Retrospectively, the data from the patients were analyzed, in which at least one insemination and a maximum of eight inseminations were performed in the last five years (observation period 01.01.2014-31.12.2018) at the Women's University Hospital Homburg. The primary endpoint was the onset of a clinical pregnancy. Clinical pregnancy was correlated with the partner's total sperm count (sperm density in millions), sperm concentration and motility during insemination. These three parameters were evaluated according the World Health Organization (WHO) 2010 guidelines. The results of the spermiograms were correlated with clinical pregnancy outcome. The data were examined for 138 women with sterility, in which a total of 345 inseminations were performed (median 2.5 per woman, range 8 inseminations). There was no correlation found between spermiogram parameters and pregnancy probability in any of the inseminations. After 5 inseminations no further pregnancy occurred. The present study showed no correlation between the conception probability of intrauterine insemination (IUI) and the total sperm count/concentration/motility. After the sixth IUI, we no longer found conceptions in our patient collective. Therefore, data from this study indicate that intrauterine inseminations can be performed at all severity levels of oligoasthenozoospermia. However, the treatment should be limited to five attempts.

Is vimentin a potential prognostic factor for patients with triple-negative breast cancer?

OBJECTIVE: To evaluate the prognostic potential of vimentin, p53, EGFR, CK5/6, CK 14, and CK 17 in patients with triple-negative breast cancer (TNBC). MATERIAL AND METHODS: Tumor specimens of 60 patients with histologically confirmed TNBC were retrospectively analyzed. Formalin-fixed paraffin-embedded blocks of the tumor tissue were used to prepare tissue microarrays (TMAs). After immune-histochemical staining, protein expression of vimentin, p53, EGFR, CK5/6, CK 14, and CK 17 was determined and the immunoreactive score (IRS) was calculated. The protein expression was correlated to overall (OS) and disease-free survival (DFS). RESULTS: Ninety percent of patients suffered from an invasive ductal carcinoma T1 or T2, 66.7% were N0, and 70% had a G3 tumor with Ki67 of > 14%. Vimentin expression was found in 28/60 patients (46.7%), p53 expression in 30/60 patients (50%), and EGFR expression in 3/60 patients (5%). CK5/6, CK14, and CK17 expression was found in 60.0%, 63.3%, and 66.7%, respectively. Vimentin expression vs no expression was associated with significantly higher mean Ki67 values (52.5% vs. 31.1%; p = 0.0013) and significantly higher p53 expression (67.9% vs. 34.4%; p = 0.0097). No significant association between vimentin expression and OS (p = 0.7710) or DFS (p = 0.5558) was found during a mean follow-up of 92 months. CONCLUSION: None of the six proteins proved to be suitable prognostic factors for OS and DSF in patients with TNBC.

Postoperative non-traumatic compartment syndrome (PNCS) in gynecologic surgery.

PURPOSE: The postoperative non-traumatic compartment syndrome (PNCS) is a rare, but serious postoperative complication. Etiology, risk factors and clinical manifestation of PNCS are not well characterized since data in gynecologic and obstetric patients are limited. METHODS: We performed a retrospective monocentric study of patients who underwent surgery for gynecologic or obstetrics conditions and identified five cases of PNCS, which were analyzed and compared to a control cohort in regard of incidence, clinical presentation, risk factors and clinical outcome. RESULTS: Five cases of PNCS were identified among 19.432 patients treated between 2008 and 2019 with an incidence rate of 0.026%. The clinical examination was shown to be unreliable, lacking sensitivity in most clinical signs. Young age, obesity and long operation time were risk factors for the development of a PNCS. Fasciotomy for the treatment of a PNCS should not be delayed, since permanent function loss may occur early. CONCLUSION: A low threshold of clinical suspicion might be prudent to identify PNCS following gynecologic surgery. In the presence of the described risk factors, any suspicion of a PNCS should be evaluated further and if necessary treated with fasciotomy urgently.

The Onset of Urinary Incontinence in Different Subgroups and its Relation to Menopausal Status: A Hospital-based Study.

BACKGROUND/AIM: Numerous risk factors have been reported to influence the development of urinary incontinence (UI). In this study, we took a closer look on the different forms of UI and tried to identify differences in regard to potential risk factors. Of special interest was the onset of UI symptoms and its relation to menopausal status. PATIENTS AND METHODS: This was a hospital-based analysis of patients who presented with urinary incontinence in the outpatient ward of a tertiary hospital. The diagnosis of urinary incontinence was based on the subjective complaints of patients. Data concerning menopausal status, hormone replacement therapy, prior hysterectomy were assessed. RESULTS: The mean age was 53.8 years in the SUI group, 62.7 years in the MUI group and 66.1 years in the UUI group, respectively (p<0.001). The proportion of patients with UUI was higher in the postmenopausal group, whereas the proportion of SUI was higher in the premenopausal group (p<0.001). The mean age in which complaints occurred was significantly lower in the SUI group (45.4 years) compared to the MUI (51.0 years) and UUI groups (54.7 years) (p<0.001). There was no correlation between menopausal status and onset of urinary incontinence (p=0.143). CONCLUSION: Additional anamnestic information help further characterize the different types of urinary incontinence that can lead to an optimization of treatment options. Younger age and premenopausal status were accompanied by milder forms of UI while menopausal status itself had no influence on the onset of UI symptoms indicating that age-related changes may lead to different types of incontinence.

VEGF-A165b levels are reduced in breast cancer patients at primary diagnosis but increase after completion of cancer treatment.

The antiangiogenic splice variant VEGF-A165b is downregulated in a variety of cancer entities, but little is known so far about circulating plasma levels. The present analysis addresses this question and examines circulating VEGF-A/VEGF-A165b levels in a collective of female high-risk breast cancer patients over the course of treatment. Within the SUCCES-A trial 205 patients were recruited after having received primary breast surgery. Using ELISA VEGF-A/VEGF-A165b concentrations were determined and correlated to clinical characteristics (1) before adjuvant chemotherapy, (2) four weeks and (3) two years after therapy and compared to healthy controls (n = 107). VEGF165b levels were significantly elevated after completion of chemotherapy. Within the breast cancer cohort, VEGF-A165b levels increased two years after completion of chemotherapy. VEGF-A plasma concentrations were significantly elevated in the breast cancer cohort at all examined time points and decreased after treatment. VEGF-A levels two years after chemotherapy correlated with increased cancer related mortality, no such correlation could be found between VEGF-A165b and the examined clinical characteristics. Compared to controls, VEGF-A/VEGF-A165b ratios were decreased in patients before and after chemotherapy. Our data suggests that circulating VEGF-A165b is significantly reduced in women with primary breast cancer at time of diagnosis; furthermore, levels change during adjuvant treatment.

A standardized simulation training program to type 1 loop electrosurgical excision of the transformation zone: a prospective observational study.

PURPOSE: To evaluate a simulation-based standardized training program for type 1 loop electrosurgical excision procedure (LEEP) under direct colposcopic vision in postgraduate teaching. METHODS: Seventeen participants (five experienced and 12 novice surgeons) performed 170 simulated cervical excisional procedures. Each participant performed 10 type 1 (cone length between 8 and 10 mm) excisional procedures under direct colposcopic vision on a low-fidelity simulator. Length of specimen was measured after each excision allowing the surgeons a subsequent resection to ensure a cone length of more than 8 mm. Main outcome measures were cone length, specimen fragmentation, and a self-developed score (LEEP score), which allowed the simultaneous evaluation of both measured parameters. RESULTS: The precision of the excision showed statistically significant improvement in the novice group during the training procedures after five procedures [LEEP score 1.61 (SD 1.34) vs. 0.46 (SD 0.58); p = 0.023], while experts showed consistently high performance. Inexperienced surgeons performed more frequently cuts that were too deep than experienced surgeons (33/120, 27.5% vs. 4/50, 8%; p = 0.003). CONCLUSIONS: Low-fidelity simulation training seems to be an effective method for learning the accurate cone length for a type 1 excision for novice surgeons. As excessive excisions are related with high risk for premature delivery in subsequent pregnancies, in our opinion, LEEP should be practiced in simulation training, especially before performing in woman of reproductive age.

Patient satisfaction with personal patient care (PPC) in the inpatient treatment of endometriosis.

PURPOSE: The aim of this retrospective cohort study was to validate patient's satisfaction and surgical complication rate in patients treated at a certified endometriosis centre with personal patient care (PPC). METHODS: The implementation of PPC at a gynaecologic treatment centre was retrospectively evaluated by analysing perioperative complications using the Clavien Dindo (CD) classification and patient satisfaction utilizing the Picker Patient Experience Questionnaire (PPE-15) for a total of 219 symptomatic endometriosis patients treated surgically at a certified endometriosis centre (Agaplesion Diakonie Hospital, Kassel, Germany) between November 2018 and April 2019. Data from our sample on complication rates and satisfaction were compared with those from reference samples published by Radosa et al. and Jenkinson et al. RESULTS: An overall complication rate of 10.96% (24 out of 219 patients) was observed. Four endometriosis patients (1.83%) had major complications with complications grade III according to the CD classification system. 155 patients out of 219 chose to answer the PPE-15 (return rate 70.78%). 92 patients (59.35%) reported about problems during their treatment in our hospital in their PPE-15. "Doctors sometimes talked as if I was not here" was the best rated item (1.2%) in our cohort. "Staff gave conflicting information" was the most mentioned item (33.55%) by patients during their hospital stay in relation to patient dissatisfaction. CONCLUSION: Incorporation of PPC in the surgical inpatient treatment of endometriosis patients resulted in a low postoperative complication rate and a high patient satisfaction in our study cohort. Furthermore, nursing staff of endometriosis patients also needs particular attention.

Conisation course for medical students-experience from a German University Hospital

Objective: Conisation of the cervix is one of the most common surgical procedures in gynaecology. Nevertheless, surgical expertise is required because if the cone is too small, the oncological risk increases and if the cone is too large, the obstetric risk increases. The aim of this prospective study was to investigate the suitability of an in-house conisation simulator for teaching medical students the practical performance of conisation. Material and Methods: Following a demonstration, students performed a loop conisation with a target depth of 8-10 mm using the simulator. Cone biopsy dimensions were analysed and a loop electrosurgical excision procedure (LEEP) score was calculated. The students were surveyed using a questionnaire of 12 items with five possible responses for each in order to investigate the suitability and realism of the teaching experience. Results: Eighty-nine students participated in the course. The median (range) cone depth was 8 (3-25) mm with a standard deviation of 3.3 mm. The observed LEEP score amounted to 1.5. The questionnaire was answered by 88 students and completed by 86. Survey results showed the course was consistently rated as positive, especially towards the increase in practical skills. The questionnaire item producing the highest score was "I enjoyed the course" while the statement "I have gained enough self-confidence for the application of high-frequency surgery" received the lowest approval score. Students considered the course to be realistic and a helpful teaching exercise. Conclusion: Practical surgery exercises on the surgical simulator were received positively. Simulation training could be extended to other gynaecological operations and to other medical subjects.

Evaluating the use of Clavien-Dindo classification and Picker Patient Experience Questionnaire as quality indicators in gynecologic endoscopy.

PURPOSE: Over the last few decades, laparoscopy has become a standard procedure within gynecological surgery. Validated quality indicators for the determination of the objective (perioperative complications) and subjective (patient satisfaction) quality of treatment as a surrogate parameter for the success of the treatment have so far found no regular application in the clinical routine. The purpose of this study was to evaluate the use of the Clavien-Dindo (CD) classification for postoperative complications and the Picker Patient Experience Questionnaire (PPE-15) as tools in the evaluation of endoscopic therapies in clinical routine. METHODS: Retrospectively, perioperative complications using the CD classification and patient satisfaction utilizing the PPE-15 were reviewed for a total of 212 consecutive patients at a gynecologic endoscopic referral center (Agaplesion Diakonie Kliniken, Kassel, Germany) in September 2018. RESULTS: An overall complication rate of 13.21% (28 out of 138 patients) was observed. Five patients (2.36%) had complications grade III and above according to the CD classification system. 138 patients out of 212 chose to answer the PPE-15 (return rate 65.01%). 112 patients (81.16%) reported about problems during their treatment in our hospital in their PPE-15. "Purpose of medicines not explained" was the most mentioned item (28.99%) by patients during their hospital stay. CONCLUSION: CD classification and PPE-15 may be helpful instruments to evaluate the quality of care in gynecology. The application of both instruments for the assessment of treatment quality in clinical routine should be further investigated in prospective studies.
