BACKGROUND: There are limited data available to indicate whether oncological outcomes might be influenced by the uterine manipulator, which is used at the time of hysterectomy for minimally invasive surgery in patients with endometrial cancer. The current evidence derives from retrospective studies with limited sample sizes. Without substantial evidence to support its use, surgeons are required to make decisions about its use based only on their personal choice and surgical experience. OBJECTIVE: To evaluate the use of the uterine manipulator on oncological outcomes after minimally invasive surgery, for apparent early-stage endometrial cancer. STUDY DESIGN: We performed a retrospective multicentric study to assess the oncological safety of uterine manipulator use in patients with apparent early-stage endometrial cancer, treated with minimally invasive surgery. The type of manipulator, surgical staging, histology, lymphovascular space invasion, International Federation of Gynecology and Obstetrics stage, adjuvant treatment, recurrence, and pattern of recurrence were evaluated. The primary objective was to determine the relapse rate. The secondary objective was to determine recurrence-free survival, overall survival, and the pattern of recurrence. RESULTS: A total of 2661 women from 15 centers were included; 1756 patients underwent hysterectomy with a uterine manipulator and 905 without it. Both groups were balanced with respect to histology, tumor grade, myometrial invasion, International Federation of Gynecology and Obstetrics stage, and adjuvant therapy. The rate of recurrence was 11.69% in the uterine manipulator group and 7.4% in the nomanipulator group (P<.001). The use of the uterine manipulator was associated with a higher risk of recurrence (hazard ratio, 2.31; 95% confidence interval, 1.27e4.20; P¼.006). The use of uterine manipulator in uterus-confined endometrial cancer (International Federation of Gynecology and Obstetrics [FIGO] IeII) was associated with lower disease-free survival (hazard ratio, 1.74; 95% confidence interval, 0.57e0.97; P¼.027) and higher risk of death (hazard ratio, 1.74; 95% confidence interval, 1.07e2.83; P¼.026). No differences were found regarding the pattern of recurrence between both groups (chi-square statistic, 1.74; P¼.63). CONCLUSION: In this study, the use of a uterine manipulator was associated with a worse oncological outcome in patients with uterusconfined endometrial cancer (International Federation of Gynecology and Obstetrics IeII) who underwent minimally invasive surgery. Prospective trials are essential to confirm these results.
total of 13,324 patients were used to verify the feasibility and effectiveness of the treatment using data from three hospital tumor registries. Additionally, five machine learning approaches were used to develop prediction models, including LADT (Logical Analysis of Data Trees), NBT (Naïve Bayes Trees), RF (Random Forests), RT (Random Trees), and FT (Functional Trees). ResultsThe experimental results indicate that the RF model was of the highest accuracy. The results suggest that six of the most important recurrent risk factors were behavior, age, tumor metastasis, grade, surgical margins, and pathological stage. Conclusion These risk factors should be monitored for early detection and the clinical features summarized in this study as additional effective treatments and appropriate interventions.
BackgroundAdolescent women are a special age group affected by human papilloma virus (HPV). Most guidelines recommend surgical treatment for high-grade cytological lesions. However, some reports have attempted to demonstrate that the immune system is fully capable of clearing the virus without using conization. Our aim in this study was to describe the outcome of women <25 years old with high-grade cytology pap smears and no histologically confirmed cervical intraepithelial neoplasm [CIN] III.MethodsThis prospective cohort study, carried out at the Department of Obstetrics and Gynecology, Hospital 12 de Octubre, included 29 women aged 25 years or younger with high-grade cytological lesions recruited in screening programs and were followed up at 15 months. This study describes the clinical course of the women, and we determined the percentage of cytological, histological, and microbiological lesions produced by HPV that were cleared without surgical treatment in these women during their follow-up.ResultsDuring follow-up, 63% of high-grade cytological lesions and all high-grade histological lesions were cleared. HPV was eliminated from 23% of patients with one HPV serotype and 27% with multiple HPV serotypes without any treatment.ConclusionThese results suggest that there is no need to use surgical treatment to clear high-grade cytological and cervical lesions in adolescent women, thus preventing damage to their reproductive future.
Nasal tip surgery has been evaluated with respect to correction of the lower lateral cartilages. Indications, techniques, results, and complications related to three generic approaches to the lower lateral cartilages are described. In 673 consecutive rhinoplasties the commonest type of nasal tip surgery was excisional, utilizing either a marginal or cartilage splitting technique. These techniques were utilized: 1. to accomplish debulking, and 2. to accomplish the installation of facets. The excisional technique found its greatest utility in primary rhinoplasties. The version technique, utilizing a change of direction of the thrust of the lower lateral cartilages was utilized in a variety of situations, particularly for the correction of moderately congenitally hypoplastic tip cartilages. It also found great utility in surgery of the Negro or cleft palate nose, increasing tip projection, correcting unacceptable bifidity, and in revision rhinoplasty. Augmentation rhinoplasty, utilizing conchal cartilage as an elastic strut was particularly useful for severe hypoplastic cartilage deficits, the Negro nose, columellar retraction, and alar rim deficits. The overall complication rate of lower lateral rhinoplasty was 17.4 percent. The rate of unacceptable complications related to lower lateral rhinoplasty was 2.7 percent.
Frequencies of MMR loss of expression were: MLH1/PMS2 loss in 14, MSH2/MSH6 loss in 5, MSH6 loss in 5, and PMS2 loss in 2. Six patients (5.6%) had germline mutations suggestive of LS with 2 (1.9%) among them having positive family history. Stage at diagnosis did not differ significantly between dMMR and pMMR. Lymphovascular invasion (LVI) (p = 0.003), and grade 2-3 (p = 0.002) were significantly more frequent in the dMMR group. Two-year recurrence-free survival (RFS) in pMMR and dMMR groups were 86% and 91% (p=0.8) respectively, while median RFS was not reached in either group. Conclusion Almost one in four EC tumours is dMMR, with higher MMR reflexed detection of LS than by family history criteria. Higher grade and LVI were more common in dMMR but short-term outcomes were similar in dMMR and pMMR.
Background: The inflammatory reaction after a surgical intervention could exacerbate the course of the COVID-19. We aim to determine the rate of COVID-19 and its complications among gynecological surgeries in the context of different measures taken during the pandemic period in our department. Methods: A retrospective longitudinal observational study was conducted. Clinical records of patients who underwent gynecological surgery from March 1 st to April 10 th , 2020 were reviewed. During this period, three different approachs were made: first phase, without any screening or surgical restrictions; second phase, with presurgical epidemiological screening using a specific questionnaire; and third phase, also with presurgical SARS-COV-19 RT-PCR. During the second and third phases the surgical activity and complexity were restricted, and different workflows were established for patient with suspected/confirmed infection. After hospital discharge, telephone follow-up was performed and screening for COVID-19 was carried out. Complications from the disease were analyzed. Results : Of the 118 patients that underwent gynecological surgeries, 10 (8.5%) were perioperatively diagnosed with COVID-19. Of these patients, 8 (80%) were not pre-surgical screened for SARS-CoV-2 infection, neither clinical nor with RT-PCR. The other 2 (20%) were preoperative screened with RT-PCR, one of them with a positive test result. Screening false negative rate was 0.8%. No postoperative complications derived from COVID-19 were observed. Conclusions: The establishment of different surgical workflows, the reduction of surgical complexity, and the use of a pre-surgical screening to detect patient at SARS-CoV-2 infection risk, could reduce the postoperative complications derived from that infection and improve surgical outcomes.
