RESUMO
INTRODUCTION: There is a growing emphasis on proficiency-based progression within surgical training. To enable this, clearly defined metrics for those newly acquired surgical skills are needed. These can be formulated in objective assessment tools. The aim of the present study was to systematically review the literature reporting on available tools for objective assessment of minimally invasive gynecological surgery (simulated) performance and evaluate their reliability and validity. MATERIAL AND METHODS: A systematic search (1989-2022) was conducted in MEDLINE, Embase, PubMed, Web of Science in accordance with PRISMA. The trial was registered with the Prospective Register of Systematic Reviews (PROSPERO) ID: CRD42022376552. Randomized controlled trials, prospective comparative studies, prospective single-group (with pre- and post-training assessment) or consensus studies that reported on the development, validation or usage of assessment tools of surgical performance in minimally invasive gynecological surgery, were included. Three independent assessors assessed study setting and validity evidence according to a contemporary framework of validity, which was adapted from Messick's validity framework. Methodological quality of included studies was assessed using the modified medical education research study quality instrument (MERSQI) checklist. Heterogeneity in data reporting on types of tools, data collection, study design, definition of expertise (novice vs. experts) and statistical values prevented a meaningful meta-analysis. RESULTS: A total of 19 746 titles and abstracts were screened of which 72 articles met the inclusion criteria. A total of 37 different assessment tools were identified of which 13 represented manual global assessment tools, 13 manual procedure-specific assessment tools and 11 automated performance metrices. Only two tools showed substantive evidence of validity. Reliability and validity per tool were provided. No assessment tools showed direct correlation between tool scores and patient related outcomes. CONCLUSIONS: Existing objective assessment tools lack evidence on predicting patient outcomes and suffer from limitations in transferability outside of the research environment, particularly for automated performance metrics. Future research should prioritize filling these gaps while integrating advanced technologies like kinematic data and AI for robust, objective surgical skill assessment within gynecological advanced surgical training programs.
RESUMO
OBJECTIVE: To assess the feasibility, safety, oncological, and obstetric outcomes in patients with cervical tumors >2 cm treated with neoadjuvant chemotherapy in preparation for abdominal radical trachelectomy. METHODS: A retrospective analysis of patients with cervical cancer >2 cm (up to 6 cm) was conducted in patients who were selected to receive neoadjuvant chemotherapy before abdominal radical trachelectomy. Surgical and clinical outcomes were examined in relation to radiological and pathological results. In addition, obstetric outcomes were described. The Mann-Whitney U test and Fisher's exact test were performed to compare radiological findings between successful and unsuccessful abdominal radical trachelectomy procedures. International Federation of Gynecology and Obstetrics (FIGO) 2009 staging classification was used for this study. RESULTS: A total of 19 women were treated with neoadjuvant chemotherapy for cervical tumors >2 cm at our institution between May 2006 and July 2018. The median age was 28 years (range 19-36). The distribution of FIGO stages was seven patients stage IB1 (37%), 10 patients stage IB2 (53%), and two patients (10%) stage IIA. Mean clinical tumor size was 4.4 cm (range 3.5-6.0). Histology revealed 74% cases of squamous cell carcinoma. The remaining patients had adenocarcinoma (21%) and only one patient had clear cell adenocarcinoma (5%). Chemotherapy consisted of six weekly cycles of cisplatin (70 mg/m2) and paclitaxel (70 mg/m2). In 15 of the 19 patients (74%) fertility was successfully preserved. In the four patients in whom fertility preservation failed, one patient had stable disease after three cycles and did not meet the criteria for fertility-sparing surgery and three patients had intra- or post-operative indications for adjuvant therapy. Three of the 19 patients (15.7%) had a relapse, two of whom died. One case was in the group of successful abdominal radical trachelectomy. CONCLUSION: Neoadjuvant chemotherapy followed by fertility-sparing surgery may be a feasible and safe option in select patients with cervical tumors >2 cm. Unfavorable prognostic factors are defined as non-responsiveness and non-squamous pathology, which can help in patient selection for fertility-sparing surgery.
