Prevalence of hysteroscopic findings and histologic diagnoses in patients with abnormal uterine bleeding

Objective: To describe the prevalence of hysteroscopic findings and histologic diagnoses inpatients with abnormal uterine bleeding (AUB).Design: Retrospective series of consecutive patients.Setting: Tertiary care University hospital and private office.Patient(s): Four thousand fifty-four hysteroscopies with biopsy in patients with AUB evaluated between June 1993 and December 2004.Intervention(S): Hysteroscopies were performed using 2.9-mm or 4-mm telescopes with CO2 or saline as the distension media. Biopsies were (lone with a 5-mm grasper or with a Novak's curette.Main Outcome Measure(s): Prevalence of hysteroscopic findings and histologic analysis of biopsies.Result(S): Endometrial polyp was the most frequent hysteroscopic finding, accounting for 1,374 (33.9%) cases. Normal uterine cavity and cervical canal were found in 814 (20.1%) patients. Submucous fibroids were diagnosed in 302 (7.5%) women. Normal endometrium was the most frequent histologic diagnosis, accounting for 1,888 (46.6%) cases. Endometrial polyp was found in 1, 115 (27.5%) patients. Endometrial hyperplasia was diagnosed in 613 (15.1%) and endometrial cancer in 105 (2.6%) women.Conclusion(s): Endometrial polyps are the most frequent hysteroscopic findings in patients with AUB, whereas normal endometrium is the most frequent histologic diagnosis.

Validation of hysteroscopic view in cases of endometrial hyperplasia and cancer in patients with abnormal uterine bleeding

STUDY OBJECTIVE: To validate hysteroscopic view with histology in cases of endometrial hyperplasia and cancer in patients with abnormal uterine bleeding (AUB)DESIGN: Retrospective study.(Canadian Task Force classification II-3).SETTING: University teaching hospitals in Rio de Janeiro and São Paulo, and private office in Rio de Janeiro.PATIENTS: Four thousand and fifty-four patients with AUB in whom hysteroscopic views were complete and the histologic result was conclusive.INTERVENTION: Four thousand and fifty-four office hysteroscopies with complete views and conclusive histologic results. The material for histologic examination was obtained through biopsy of the lesion in an outpatient unit or through the resection of the entire lesion in patients who underwent surgery. Histology was considered the gold standard and compared with the hysteroscopic view.MEASUREMENTS AND MAIN RESULTS: In the histology of the 4054 examinations, 613 (15.2%) were endometrial hyperplasia, and 105 (2.6%) were endometrial cancer. The most frequent hysteroscopic finding was endometrial polyps (31.2%). In endometrial hyperplasia, the sensitivity of the hysteroscopic view was 56.3% (95% CI 52.21-60.2%), specificity was 89.1% (95% CI 88.0%-90.1%), positive predictive value (PPV) was 48.0% (95% CI 44.3%-51.7%), negative predictive value (NPV) was 92.0% (95% Cl 90.1%-92.9%), and accuracy was 72.7% (95% CI 70.7%-74.7%). Accuracy was defined as the proportion of correct results among the hysteroscopic examinations. In endometrial cancer, the sensitivity of the hysteroscopic view was 80.0% (95% Cl 71.1%-87.2%), specificity was 99.5% (95% CI 99.2%-99.7%), PPV was 81.5% (95% Cl 72.7%-88.5%), NPV was 99.5% (95% CI 99.2%-99.7%), and accuracy was 89.8% (95% CI, 85.9%-93.6%). In the 814 patients (20.0%) in whom the hysteroscopic view was normal, there were no false negatives for endometrial cancer; however, there were 37 (4.5%) false negatives for endometrial hyperplasia. In the histologic cases of endometrial cancer, 101 (96.2%) hysteroscopic views were compatible with cancer or hyperplasia (80.0% and 16.2%, respectively). Ninety-seven out of 103 hysteroscopic views with cancer findings (94.2%) had histologic diagnosis of cancer or hyperplasia (81.5% and 12.6%, respectively).CONCLUSION: It seems that even in face of good validity of hysteroscopic view for endometrial hyperplasia and cancer, histologic study is mandatory in the presence of any lesion as the hysteroscopic view cannot completely replace the histologic study in patients with AUB.

Criteria for the diagnosis of diffuse uterine myohypertrophy

Objectives: Diffuse uterine myohypertrophy (DUMH) is a condition clinically diagnosed by the presence of uterine bleeding, homogeneous and diffuse uterine enlargement, and absence of any myoendometrial cause of bleeding. Since the morphologic criteria for the diagnosis of this entity are still controversial, this study aimed to investigate the clinical presentation and the morphologic findings of the cases of DUMH presenting at the University Hospital of Botucatu, São Paulo, Brazil, Methods: We retrospectively studied 43 consecutive patients with DUMH submitted to hysterectomy (test group) and compared the findings with those obtained from 28 patients submitted to hysterectomy due to a prolapsed uterus (control group). There were no significant differences in age, weight or height between the two groups. Results: the uterine weight of the DUMH group (mean +/- S.D. 157.4 +/- 46.4 g) was significantly heavier than that of the control group (99.5 +/- 35.4 g) and myometrial thickness was significantly greater in the DUMH group (2.5 +/- 0.5 cm) than in the control group (1.9 +/- 0.4 cm). No positive correlation was observed between increased uterine weight and parity, but there was a positive correlation between uterine weight and myometrial thickness. on the basis of the present study, we suggest that the diagnosis of DUMH be made clinically and in cases of uterine weight greater than or equal to 120 g and myometrial thickness greater than or equal to 2.0 cm. In addition, 10 cases of each group were analyzed by morphometry to evaluate interstitial fibrosis and myometrial hypertrophy. The data showed that the increase in uterine weight in DUMH is caused by enlargement of individual myometrial fibers rather than accumulation of interstitial collagen. Conclusion: Discriminant analysis to estimate the diagnostic significance of a number of clinical and pathologic variables (age, parity, uterine weight and morphometric parameters) was able to differentiate cases of DUMH from controls in 100% of the patients.

Association between concurrent genital bleeding and cervical cancer: a cross-sectional study

Genital bleeding may be a common symptom among women with cervical cancer. Cross-sectional study evaluating whether the prevalence of cervical smear results is different in women with and without clinical information about concurrent genital bleeding. The sample consisted of 2 324 836 smears; of these, 0.4% had clinical information on genital bleeding. When stratified by age group, women with genital bleeding had a higher chance of a cytological result of a high-grade squamous intraepithelial lesion [30-49 years odds ratio (OR) 2.38; 95% confidence interval (CI) 1.60-3.53 and ≥50 years OR 6.30; 95%CI 3.72-10.67), of squamous cell carcinoma (SCC) (30-49 years OR 24.70; 95%CI 11.96-51.03 and ≥50 years OR 48.91; 95%CI 31.28-76.47) and of atypical glandular cells (30-49 years OR 5.72; 95%CI 3.30-9.93 and ≥50 years OR 11.56; 95%CI 5.96-22.45); there was also a higher chance of adenocarcinoma for women ≥50 years (OR 53.13; 95%CI 28.08-100.51). The sensitivity of genital bleeding for women aged 18-29 years was 0.4% for high-grade squamous intraepithelial lesion (HSIL); for women 30-49 years old the rate was 0.9% for HSIL, 8.6% for SCC and 2.1% for atypical glandular cells of undetermined significance (AGUS), while for women aged from 50 years or more the rates were 2.0% for HSIL, 13.7% for SCC, 3.6% for AGUS and 14.7% for adenocarcinoma. Women ≥30 years old with genital bleeding should be referred for colposcopy to rule out the possibility of cervical cancer.

Tratamento Clínico e Seguimento das Hiperplasias de Endométrio

Objetivos: avaliar a eficácia do acetato de medroxiprogesterona e do acetato de megestrol nas hiperplasias de endométrio. Métodos: foram incluídas, retrospectivamente 47 pacientes com sangramento uterino anormal, submetidas a curetagem uterina diagnóstica e/ou biópsia de endométrio, cujo achado histopatológico foi de hiperplasia de endométrio. Nas pacientes com hiperplasia sem atipia foi iniciado a terapêutica com acetato de medroxiprogesterona por via oral, na dose de 10 mg/dia durante 10-12 dias por mês. Nas com atipia, era utilizado o acetato de megestrol por via oral, dose de 160 mg/dia, uso contínuo. O período de tratamento variou de 3 a 18 meses. Biópsia de endométrio e/ou curetagem uterina de controle foram realizadas entre três e seis meses do início do tratamento e periodicamente para avaliar a resposta terapêutica. Resultados: foram analisadas 42 pacientes com hiperplasia endometrial sem atipia e cinco com atipia. A média de idade das pacientes foi de 49,5 ± 10,6 anos, sendo 70,2% com idade superior a 45 anos. O acetato de medroxiprogesterona foi eficaz em fazer regredir as hiperplasias sem atipias em 83,2% (35/42) e o acetato de megestrol em 80% (4/5) das hiperplasias com atipia. em 16,8% (7 casos) das hiperplasias sem atipia e em 20% (1 caso) das com atipia, ocorreu persistência das lesões, apesar do tratamento. em nenhum caso ocorreu progressão para câncer de endométrio, durante o período de seguimento que foi de 3 meses a 9 anos. No acompanhamento dessas pacientes, verificamos que 18 (38,3%) apresentaram amenorréia, em 12 (25,5%) ocorreu regularização do ciclo menstrual e 17 (36,2%) permaneceram com sangramento uterino anormal, sendo submetidas a histerectomia total abdominal. O exame anatomopatológico mostrou a persistência da lesão hiperplásica em oito casos, leiomioma em quatro, adenomiose em três, mio-hipertrofia uterina difusa em um caso e útero normal em outro, tendo havido regressão das lesões hiperplásicas nesses últimos nove casos. Conclusões: o tratamento das hiperplasias de endométrio com acetato de medroxiprogesterona e/ou acetato de megestrol, representa uma alternativa satisfatória para mulheres que desejam preservar o útero ou que tenham risco cirúrgico elevado. Entretanto, é necessário monitorização cuidadosa do endométrio, o que deve ser realizado pela avaliação dos sintomas, ultra-sonografia transvaginal e biópsia periódica.

Balão Térmico para Ablação Endometrial: Resultados Preliminares

Objetivos: os autores mostram a experiência preliminar com o uso do balão térmico para ablação do endométrio em pacientes com queixas de menorragia. Pacientes e Métodos: foram submetidas a este procedimento 20 pacientes. Após exame pélvico completo e ultra-sonografia endovaginal, todas as pacientes foram submetidas à histeroscopia diagnóstica com biópsia de endométrio para excluir causas de malignidade. Das 20 pacientes que se submeteram ao tratamento com balão térmico, 16 foram submetidas em regime ambulatorial com anestesia local. O procedimento teve duração de 8 minutos e 30 segundos. Resultados: duas das 20 pacientes mostraram-se insatisfeitas, mantendo o quadro hemorrágico inalterado, e 18 pacientes referiram melhora da sintomatologia. Não houve complicações do procedimento. Conclusões: o uso do balão térmico para ablação endometrial mostrou-se seguro e eficaz para o tratamento da menorragia de causa benigna.

Repercussões hemodinâmicas do posicionamento em litotomia exagerada para histerectomia vaginal em paciente cardiopata: relato de caso

JUSTIFICATIVA E OBJETIVOS: A técnica de histerectomia vaginal possibilita menor tempo operatório e o uso do bloqueio do neuro-eixo, com os benefícios de melhor analgesia pós-operatória e menor resposta sistêmica ao procedimento cirúrgico. O objetivo deste relato foi descrever as alterações hemodinâmicas decorrentes do posicionamento em litotomia exagerada em paciente cardiopata. RELATO do CASO: Paciente de 33 anos, G0P0A0, com história de sangramento uterino anormal e anemia. A ultra-sonografia evidenciava útero miomatoso com volume estimado de 420 cm³. Ela era portadora de trombofilia e miocardiopatia dilatada, com passado de dois acidentes vasculares encefálicos isquêmicos e dois infartos agudos do miocárdio. Foi monitorizada com pressão arterial invasiva e cateter de artéria pulmonar com medida de débito cardíaco contínuo. Realizada raquianestesia com bupivacaína hiperbárica e morfina. A paciente foi posicionada em litotomia exagerada sendo realizada histerectomia total pela técnica de Heaney e salpingectomia bilateral. Como intercorrência intra-operatória apresentou diminuição do índice cardíaco e aumento das pressões de câmaras direitas após o posicionamento, necessitando do uso de dobutamina. CONCLUSÕES: O posicionamento em litotomia exagerada pode ocasionar alterações hemodinâmicas que devem ser consideradas na escolha da técnica cirúrgica.

Avaliação da cavidade uterina com histerossonografia, uma revisão

Sonohysterography was firstly described three decades ago. The saline solution infusion into the uterine cavity favors its use and provides excellent visualization of the anatomy and the inner cavity of the uterus better than the conventional transvaginal sonography To check the current role of sonohysterography in the uterine cavity assessment in women with abnormal uterine bleeding and asymptomatic, a literature review comparing sonohysterograph with conventional transvaginal sonography and/or ambulatory diagnostic hysteroscopy was carried out. To this end, relevant studies were researched in electronic databases Medline/PubMed, SciELO/LILACS. The sonohysterography is an ambulatory procedure, non-invasive, better cost-benefit, better sensitivity and specificity to identify uterine abnormalities, causing minimal discomfort and low complications rate. It was subject to revision which there is no more doubt about its accuracy. It can be concluded that the sonohysterography is a useful tool in the propedeutics to assess uterine cavity of symptomatic patients with abnormal uterine bleeding, infertility, recurrent miscarriages, and embryonic implantation failures in assisted reproduction treatment / in vitro fertilization and in any other intra and extra uterine cavity alteration. Hence, conventional transvaginal sonography is indicated as an initial method of assessment of the uterine cavity previously to ambulatory diagnostic hysteroscopy.

Caratteristiche cliniche ed ecografiche dei Sarcomi Uterini

Obiettivo: descrivere le caratteristiche ecografiche e flussimetriche dei sarcoma uterini Materiali e Metodi: Dall'archivio anatomopatologico di due cliniche Universitarie sono state reclutate retrospettivamente tutte le pazienti con diagnosi anatomopatologica di sarcoma uterino. Tutte le cartelle cliniche, le immagini e i filmati digitalizzati sono stati analizzati e dati raccolti in un database. Risultati: Sono stati inclusi nello studio 49 casi, che comprendono 17 leiomiosarcoma, 14 sarcoma dello stroma endometriale e 18 carcinosarcoma. L'età media alla diagnosi è stata 62 anni (range 35-87). L'ottanta per cento delle pazienti erano in menopausa al momento della diagnosi. Circa la metà delle pazienti presentavano sanguinamento anomalo e il 20% dolore pelvico. La maggior parte delle lesioni sono apparse iso-ipoecogene, senza coni d’ombra (47/49;96%). Conclusioni: I sarcomi uterini sono un gruppo eterogeneo di tumori che presentano aspetti ecografici diversi anche in relazione all’istotipo. Conoscere le diverse caratteristiche può essere utile ai fini di una corretta diagnosi. Nel nostro studio l’assenza dei coni d’ombra risulta essere l’aspetto più significativo.
