LiNA OperaScope^(TM) for microwave endometrial ablation for endometrial polyps with heavy menstrual bleeding: A case report

BACKGROUND The procedure for microwave endometrial ablation(MEA)follows established MEA practice guidelines but requires hysteroscopic observation of the uterine lumen before and after MEA.When a luminal uterine lesion is recognized,its removal requires preoperative dilation of the cervix because the outer diameter of a conventional rigid hysteroscope is 8.7 mm.Recently,a fully disposable rigid hysteroscope(LiNA OperaScope^(TM))with a narrow diameter(4.4 mm)and forceps capable of extracting endometrial lesions has become available.CASE SUMMARY Here,we report a case of heavy menstrual bleeding(HMB)complicated by endometrial polyps where MEA was performed after removing endometrial polyps using the LiNA OperaScope^(TM) device.A 48-year-old woman with three prior pregnancies and three deliveries was referred to our hospital for further examination and treatment after being diagnosed with HMB 2 years earlier.The patient underwent MEA following endometrial polypectomy using LiNA OperaScope^(TM).After MEA,endometrial cauterization was again examined using the LiNA OperaScope^(TM),and the procedure was completed.No preoperative cervical dilation was performed.The patient’s clinical course was favorable,and she was discharged 3 h after surgery.One month after surgery,menstruation resumed,and both HMB and dysmenorrhea improved markedly from 10 preoperatively to 1 postoperatively,as assessed subjectively using the visual analog scale.The patient’s postoperative course was uneventful with no complic-ations.CONCLUSION LiNA OperaScope^(TM) can be a minimally invasive treatment for MEA of HMB with uterine lumen lesions.

Application of Whole-Process Management in Day Surgery for Endometrial Polyp

Objective:To explore the effect of whole-process management model in nursing management of endometrial polyp day surgery.Methods:266 patients that underwent endometrial polyp day surgery from January to December 2022 were selected for this study,and they were separated into an observation group(131 patients)and a control group(135 patients);the clinical data of the two groups were compared.Results:After intervention,the scores of Hamilton Anxiety Scale(HAM-A)of the patients in the observation group were lower than those in the control group(P<0.05).The rate of postoperative complications in the observation group was lower than that in the control group(P<0.05),and the satisfaction degree of the patients in the observation group was higher than that in the control group(P<0.05).Conclusion:The application of the whole-course management model in endometrial polyp day surgery can alleviate patients’anxiety,ensure the quality and safety of day surgery nursing,and improve patients’satisfaction.

Multicentric Study on Endometrial Polyps and Endometriosis: Are They True or False Friends?

Many authors have reported an epidemiologic relationship between endometrial polyps and endometriosis. The joining link could be an unopposed and unbalanced estrogenic milieu. The prevalence of both, endometrial polyps and endometriosis, is quite high among general population. The presence of endometrial polyps and endometriosis could affect infertile women. We performed a retrospective multicentric study, based on data collected from three Hospitals (S. Antonio Abate, Trapani, Civico-Ascoli, Palermo, and Cannizzaro, Catania). We analyzed 285 women undergoing diagnostic/office hysteroscopy. Clinical history demographic and hysteroscopic data were collected in the same sheet, containing within informed consent. On the base of our results no relationship exists between endometrial polyps and endometriosis nor cervical polyps. It’s the first time that none correlation is proved for the coexistence of endometrial polyps and endometriosis. Further research is needed.

Vascular markers CD31,CD34,actin,VEGFB,and VEGFR2,are prognostic markers for malignant development in benign endometrial polyps

Intention of the study: The prevalence of endometrial polyps has been demonstrated in between 10% and 35% of all women, but knowledge regarding malignant potential within polyps is limited. Even though premalignant and malignant changes have been reported in up to 24% of all cases, no objective tissue markers have ever been developed for routine diagnostics to select high risk cases. As vascular changes and activation of endometrial angiogenesis has been demonstrated in former studies, our main objective was to evaluate different members of the angiogenic pathway as potential risk factors for cancer development. Patients and methods: Formalin-fixed, paraffin-embedded tissue from 15 women with benign endometrial polyps, and 16 women diagnosed with endometrial cancer were included. Immunohistochemical investigation with antibodies against VEGF, VEGF-B, VEGFR2, VEGFR3, CD31, CD34, actin, and factorVIII was performed, followed by evaluation of staining intensity of microvessels, evaluation of H-score in glands (cell membrane, cytoplasm) and stroma, and measurement of micro vessel density. Results: Expression of CD31 in microvessels was significantly stronger in cancers compared to endometrial polyps (P = 0.006 for arterioles, P = 0.038, for venyles, and P = 0.002 for capillaries, respectively), whereas, a reverse change was shown for CD34. Expression of actin in capillary walls was also significantly increased in cancers compared to polyps (P = 0.002). No significant difference was found for staining intensity in microvessels (arterioles, venyles or capillaries) in endometrial benign polyps compared with endometrial cancers for VEGF, VEGFB, VEGFR2, VEGFR3, or Factor VIII. Also no difference in H-score values between benign polyps and endometrial cancers could be detected in glandular epithelium, in epithelial cell membrane or in stroma for VEGFR3, CD31 or Factor VIII. Conclusions: The present study strongly indicates that activation of angiogenesis differs in benign endometrial polyps and endometrial cancers. Thus, immunohistochemical expression of specific angiogenic markers may be of great importance as prognostic factors in the routine diagnostics of this lesion. The ratio between stromal expression of CD34 and actin might be of particular interest to select polyps with increased malignant potential.

Endometrial Polyps:Which Patients Should Be Selected for Hysteroscopic Surgery?--A Study Using Data from the Swedish National Quality Registry of Gynecological Surgery

Objective: To illuminate the findings after hysteroscopic surgery of endometrial polyps. Method: Data were extracted from The Swedish National Quality Registry of Gynecological Surgery. Endometrial polyps were identified in 1934 cases in a total of 4512 hysteroscopic operations. Data on all hysteroscopic procedures registered as surgery of endometrial polyps between 1997 and January 2013 were analyzed with logistic regression analysis and effect size was calculated. Main outcome measure was malignancy in endometrial polyps. Results: The most frequently reported symptoms of endometrial polyps were: postmenopausal bleeding, metrorrhagia, pain, and infertility. Among the registered biopsies, there were: 30 malignancies (1.8%), and 41 dysplasias (2.5%). The remaining polyps were benign. Only 1/30 cancer patients were <52 years old (p < 0.001). Among those women with dysplasia, 12/41 (29%) were p = 0.07). All cancer patients at age ≥52 had postmenopausal bleeding. The <52-year-old cancer patient had treatment-resistant bleeding. Increasing weight was a risk factor associated with tissue alterations in endometrial polyps (p = 0.014), controlling for age as a confounding factor. Conclusion: Hysteroscopic surgery should be recommended for women with postmenopausal bleeding and presence of endometrial polyps according to the findings of this study. The results further indicate a low risk of malignancy in premenopausal women <52 years with endometrial polyps. In those cases, it seems to be safe to refrain from surgery.

Effects of Huayu Xiaozheng Therapy on Recurrence of Multiple Endometrial Polyps After Electrotomy

Objective:To investigate the preventive effect of Huayu Xiaozheng therapy method of traditional Chinese medicine on the recurrence of multiple endometrial polyps after hysteroscopic electro resection.Methods:A total of 120 patients with blood stasis diagnosed with multiple endometrial polyps after hysteroscopic electroresection were divided into Traditional Chinese medicine group(38 people),Manyuele group(27 people),contraceptive pill group(34 people)and control group(21 people),and the endometrial thickness,polyp recurrence cases and TCM syndrome points were observed in 4 groups after treatment in 3 months,6 months and 12 months..Results:The endometrial thickness was statistically significant(P<0.05)before and after treatment in the Chinese medicine group,the Manyuele group and the contraceptive group,and the endometrial thickness was statistically significant(P<0.05)in the 1 year after treatment,and the endometrial thickness of the Chinese medicine group was compared with the contraceptive group and the Manyuele group in the 1 year after treatment,and the difference was not statistically significant.The differences in TCM symptoms in the Chinese medicine treatment group were statistically significant compared with those in the contraceptive group and the Manyuele group(P<0.05).The recurrence rate of polyps in the 1 year after treatment was statistically significant compared with the control group(P<0.05),and the difference between the three groups was not statistically significant(P>0.05).Conclusion:The traditional Chinese medicine stasis elimination method has a preventive effect on the recurrence of endometrial polyps,and its preventive effect is no different from that of Western medicine,and can significantly improve clinical symptoms.

Impact of gonadotropin-releasing hormone agonist and hormone replacement therapy on pregnancy outcomes in single euploid frozen-thawed embryo transfer for patients with endometrial polyps

Objective:Although consensus on the optimal endometrial preparation protocol for frozen-thawed embryo transfer(FET)is lacking,this is particularly true for patients with infertility and a history of endometrial polyps(EPs).In this study,we aimed to investigate whether a gonadotropin-releasing hormone agonist combined with hormone replacement therapy(GnRHa-HRT)could improve pregnancy outcomes in single euploid FET for patients with a history of EPs.Methods:In this retrospective cohort study,395 women who underwent their first single euploid FET cycle were divided into groups according to endometrial preparation protocols as follows:natural cycle(NC)(n=220),hormone replacement therapy(HRT)(n=122),and GnRHa-HRT groups(n=53).Subsequently,the FET cycles in the three groups were subdivided according to maternal age.All patients underwent hysteroscopic polypectomy before FET,and their EPs were confirmed by pathology.Results:No statistically significant differences were observed in live birth rates among the three groups(58.64%vs.58.20%vs.56.60%,P=0.964).Furthermore,the rates of miscarriage,ectopic pregnancy,premature live birth,and pregnancy complications were comparable among the three groups(P>0.05).After adjusting for potential confounding factors,no significant differences in pregnancy outcomes were reported between the groups(adjusted odds ratios[OR]and 95%credible intervals[CI]for live birth rate,HRTvs.NC:1.119,0.660–1.896,P=0.677;GnRHa-HRTvs.NC:1.165,0.610–2.226,P=0.643).Additionally,the pregnancy outcomes of the FET cycle were not influenced by the endometrial preparation protocols in the subgroups when stratified by maternal age(P>0.05).Conclusion:GnRHa-HRT did not improve the pregnancy outcomes of the single euploid FET in patients with a history of EPs.

Diagnostic value of endometrial thickness determined by transvaginal sonography in infertile women with endometrial polyps

Background Endometrial polyps （EPs） occur in approximately 34.9% of infertile women. Transvaginal sonography （TVS） is a routine, non-invasive component of fertility evaluation. Most ultrasonographic studies of EPs have focused on abnormal uterine bleeding; few have assessed EPs in infertile women. Furthermore, no studies have explored endometrial thickness and its correlation with EPs in infertile women. This study aimed to assess transvaginal sonographic assessment of endometrial thickness and its value in diagnosis and prediction of EPs in infertile women. Methods A retrospective study on 314 infertile women was conducted from June to December 2010. After TVS, endometrial biopsies were obtained by hysteroscopy. Pathologically confirmed EPs were taken as the gold standard. Results Based on recognized criteria, TVS had a sensitivity of 37.04%, specificity of 98.71%, positive predictive value of 90.91%, negative predictive value of 81.85%, and accuracy of 82.80% for diagnosing EPs. Mean endometrial thickness was significantly different in patients with and without EPs （P=0.0001）. In women in the mid and late-proliferative phase, the endometrial thickness was significantly greater in those with EPs than in those without them （P=0.0001 and 0.024）. Receiver operating characteristic analysis showed that endometrial thickness had a sensitivity of 85.2% and specificity of 38% in the diagnosis of EPs, the area under the curve being 0.64. In the mid-proliferative phase, sensitivity was up to 90.9%, the area under the curve being 0.70. Conclusions TVS is poor at detecting EPs in infertile women; however, transvaginal sonographic measurement of endometrial thickness is helpful. It is suggested that the diagnostic value of TVS for EPs in infertile women could be improved by adding the measurement of endometrial thickness to the variables that are routinely assessed.

Actual Use of Rigid Hysteroscope Intrauterine BIGATTI Shaver (IBS^®) with a Morcellator System

Hysteroscopic resection of endometrial lesions has recently gained popularities. We here report the usefulness and safety of hysteroscopic surgery using Intrauterine BIGATTI Shaver (IBS®). We performed this surgery for 6 patients: 4 endometrial polyps and 2 intrauterine myoma. The average operation time was 25.7 ± 13.2 minutes. Only a small amount of bleeding was noted in all cases. There were no surgical complications. Two out of four patients who desired childbearing became pregnant. Hysteroscopic surgery using IBS® can safely and reliably remove intrauterine protruding lesions under aspiration without using a heat source. Less endometrial damage may help preserve fertility.
