The value of endocervical curettage during large loop excision of the transformation zone in combination with endocervical surgical margin in predicting persistent/recurrent dysplasia of the uterine cervix: a retrospective study

Abstract Background Cervical cancer often originates from cervical cell dysplasia. Previous studies mainly focused on surgical margins and high-risk human papillomavirus persistence as factors predicting recurrence. New research highlights the significance of positive findings from endocervical curettage (ECC) during excision treatment. However, the combined influence of surgical margin and ECC status on dysplasia recurrence risk has not been investigated. Methods In this retrospective study, data from 404 women with high-grade squamous intraepithelial lesions (HSIL) who underwent large loop excision of the transformation zone (LLETZ) were analyzed. Records were obtained retrospectively from the hospital’s patient database including information about histopathological finding from ECC, endocervical margin status with orientation of residual disease after LLETZ, recurrent/persistent dysplasia after surgical treatment and need for repeated surgery (LLETZ or hysterectomy). Results Patients with cranial (= endocervical) R1-resection together with cells of HSIL in the ECC experienced re-surgery 17 times. With statistical normal distribution, this would have been expected to happen 5 times ( p  < 0.001). The Fisher’s exact test confirmed a statistically significant connection between the resection status together with the result of the ECC and the reoccurrence of dysplasia after surgery ( p  < 0,001). 40,6% of the patients with re-dysplasia after primary LLETZ had shown cranial R1-resection together with cells of HSIL in the ECC. Investigating the risk for a future abnormal Pap smear, patients with cranial R1-resection together with dysplastic cells in the ECC showed the greatest deviation of statistical normal distribution with SR = 2.6. Conclusion Our results demonstrate that the future risk of re-dysplasia, re-surgery, and abnormal Pap smear for patients after LLETZ due to HSIL is highest within patients who were diagnosed with cranial (endocervical) R1-resection and with cells of HSIL in the ECC in their primary LLETZ. Consequently, the identification of patients, who could benefit of intensified observation or required intervention could be improved.

Assessment of psychological distress in patients with cervical dysplasia according to age, education, information acquisition and information level

Abstract Purpose This study aims to investigate the psychological distress experienced by patients with an initial diagnosis of abnormal Pap smears or dysplastic changes of the cervix uteri. It investigated whether patients’ age, education, information level and approach to information acquisition have an impact on their psychological distress. Methods A total of 364 female patients, aged 20–80 years, referred to the special dysplasia consultation hour at the Department of Obstetrics and Gynecology, Wuerzburg, completed a questionnaire containing validated items to assess information level, information acquisition, information needs and psychological distress, including a distress thermometer. Data from questionnaires and medical reports were used for analysis. Results The study found that 56.9% of patients experienced psychological distress before their first visit. Patients under 44 years of age, especially those with concerns about fertility and sexuality, and those with lower levels of education showed higher levels of distress ( p -value = 0.018 and p -value = 0.037). 40.9% of patients felt poorly informed and 53.7% of patients wanted more information before their visit. Correlational analysis showed that the method of obtaining information correlated with the desire for more information ( p -value < 0.001). Those who received information via the Internet felt less informed, wanted more information and experienced more anxiety. Conclusion These findings highlight the need for improved patient education strategies and effective doctor-patient communication to address the knowledge gap and reduce patient distress. In addition, healthcare providers should ensure that patients have access to reliable online resources for accurate information.

Introducing a novel model for simulating large loop excision of the transformation zone (LLETZ) using 3D printing technique

Abstract Purpose Electrosurgery is the gold-standard procedure for the treatment of cervical dysplasia. The quality of the outcome depends on the accuracy of performance, which underlines the role of adequate training of surgeons, especially, as this procedure is often performed by novice surgeons. According to our knowledge, medical simulation has up until now lacked a model, which focuses on realistically simulating the treatment of cervical dysplasia with the concerning anatomy. Methods and result In our work, we present a model created using 3D printing for holistically simulating diagnostic, as well as surgical interventions of the cervix, as realistically as possible. Conclusion This novel simulator is compared to an existing model and both are evaluated. By doing so, we aim to provide novice gynecologists with standardized and high-quality simulation models for practicing to improve their proficiency.
