Submucous fibroids classification - STEP-W classification

Objective: To develop a new submucous fibroids classification for evaluating the viability and the degree of difficulty and complexity of a hysteroscopic myomectomy.Methods: We have included more four parameters in addition to penetration the fibroid into the myometrium. The extra-parameters were: size of the fibroid, it topography, it extension of the base in relation the wall was set and the wall it was set. The fibroids were classified according to the Classification of the European Society for Gynaecological Endoscopy (ESGE) and to the new classification (STEP-W) in patients who were submitted to hysteroscopic resection of submucous fibroids. The possibility of total resection of the fibroid, the operating time, the fluid deficit and the frequency of any complications were considered. The Fisher test, the Student t test and the analysis of variance test were used in the statistical analyses. It was considered statistically significant when the p-value was less than 0.05 in the two-tailed test.Results: In group which the hysteroscopic surgery was considered complete there was no significant difference between the three ESGE levels (0, 1 and 2). Using the STEP-W, the difference between the numbers of complete surgeries was significant (p < 0.001) for the two levels (groups I and II). The difference between the operating times was significant for the two classifications. In relation to the fluid deficit, only the STEP-W showed significant differences between the levels (p=0.02).Conclusions: It seems to us that the new classification (STEP-W) gives more clues to the difficulties of a hysteroscopic myornectomy than the standard classification (ESGE).

Miomas submucosos: classificação pré-operatória para avaliação da viabilidade da cirurgia histeroscópica

OBJETIVO: desenvolver uma nova classificação pré-operatória dos miomas submucosos para avaliação da viabilidade e do grau de dificuldade da miomectomia histeroscópica. MÉTODOS: conduzimos um estudo onde quarenta e quatro pacientes foram submetidas a ressecção histeroscópica de 51 miomas submucosos. Foram considerados a possibilidade da ressecção total do mioma, o tempo cirúrgico, o balanço hídrico e a incidência de complicações. Os miomas foram classificados pela classificação da sociedade Européia de Cirurgia Endoscópica (CSECE) e pela Classificação Proposta (CP) pelo nosso grupo, que, além do grau de penetração do mioma no miométrio, adiciona como parâmetros a extensão da base do mioma em relação à parede do útero, o tamanho do nódulo em centímetros e a topografia na cavidade uterina. Para análise estatística foram usados o teste de Fisher, o teste t de Student e a análise de variância. Foi considerado estatisticamente significativo quando o valor de p-valor foi menor que 0,05 no teste bicaudal. RESULTADOS: em 47 miomas a cirurgia histeroscópica foi considerada completa. Não houve diferença significativa entre os três níveis (0, 1 e 2) da CSECE. Pela CP, a diferença quanto ao número de cirurgias completas foi significativa (p=0,001) entre os dois níveis (grupos I e II). A diferença da duração da cirurgia quando se compara as duas classificações foi significativa. em relação ao balanço hídrico, apenas a CP mostrou diferenças entre os níveis (p=0,02). CONCLUSÕES: a CP inclui mais dados sinalizadores das dificuldades da miomectomia histeroscópica do que a CSECE, atualmente em uso. Deve ser enfatizado que o número de miomectomias histeroscópicas usado para essa análise foi modesto, sendo interessante a avaliação do desempenho dessa classificação em séries maiores de casos.

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.

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.

Submucous myomas: A new presurgical classification to evaluate the viability of hysteroscopic surgical treatment - Preliminary report

STUDY OBJECTIVE: To develop a new preoperative classification of submucous myomas for evaluating the viability and the degree of difficulty of hysteroscopic myomectomy.DESIGN: Retrospective study (Canadian Task Force classification II-3)SETTING: University teaching hospitals.PATIENTS: Fifty-five patients who underwent hysteroscopic resection of submucous myomas.INTERVENTION: the possibility of total resection of the myoma, the operating time, the fluid deficit, and the frequency of any complications were considered. The myomas were classified according to the Classification of the European Society for Gynaecological Endoscopy (ESGE) and by our group's new classification (NC), which considers not only the degree of penetration of the myoma into the myometrium, but also adds in such parameters as the distance of the base of the myoma from the uterine wall, the size of the nodule (cm), and the topography of the uterine cavity. The Fisher's exact test, the Student's t test, and the analysis of variance test were used in the statistical analysis. A p value less than .05 in the two-tailed test was considered significant.MEASUREMENTS AND MAIN RESULTS: In 57 myomas, hysteroscopic surgery was considered complete. There was no significant difference among the three ESGE levels (0, 1, and 2). Using the NC, the difference between the numbers of complete surgeries was significant (p < .001) for the two levels (groups I and H). The difference between the operating times was significant for the two classifications. With respect to the fluid deficit, only the NC showed significant differences between the levels (p = .02).CONCLUSIONS: We believe that the NC gives more clues as to the difficulties of a hysteroscopic myomectomy than the standard ESGE classification. It should be stressed that the number of hysteroscopic myomectomies used in this analysis was low, and it would be interesting to evaluate the performance of the classification in a larger number of patients.

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.

Hysteroscopic myomectomy in a submucous fibroid 3 mm from the serosa: A case report - Case report from the endoscopy service of Ginendo-RJ

This is a case report of a 39-year-old black woman, nulliparous, married who presented a heavy menstrual flow with clots and dysmenorrhea. Gynaecological examination of the uterus revealed RVF, mobility, no pain, slight enlargement, and right displacement. Magnetic resonance imaging (MRI) of the pelvis showed a 40 mm submucous fibroid with intramural component less than 50%, type 1, with a 3 mm distance from serosa. In an office hysteroscopy, it was noted a 40 mm submucous fibroid with an intramural component with less than 50%, type 1, classified in STEP-W submucous fibroids classification as a Score 6, Group II. The patient was submitted to partial hysteroscopic myomectomy, removing 60% of the fibroid volume in a 48.75-minute surgery. GnRH analogue was indicated for 3 months before another intervention. In the second evaluation MRI revealed a 22 mm-fibroid with intramural component more than 50%, type 2, with a 7 mm distance from serosa. Hysteroscopy found a 20 mm submucous fibroid, with intramural component more than 50%, type 2, Score 4, Group I on STEP-W classification. The patient was submitted to a second hysteroscopic myomectomy with complete removal and 10.5 minutes operating time, without complications. © 2006 Springer-Verlag.

Hysteroscopic myomectomy in a submucous fibroid near from tubal ostia and 5 mm from the serosa: A case report from the Endoscopy Service of Ginendo-RJ

This is a case report of a 27-year-old white woman, nuliparous, single, who presented a heavy menstrual flow with clots, dysmenorrhoea and anaemia. Gynaecological examination of the uterus revealed anteverted position, mobility, no pain, slight enlargement and right displacement. Magnetic resonance imaging of the pelvis showed a 29-mm submucous fibroid with intramural component more than 50%, type 2, in the posterior wall, with a 5-mm distance from serosa. In office hysteroscopy, a 30-mm submucous fibroid with an intramural component with more than 50%, type 2, near around 5 mm from left tubal ostia, classified in STEP-W submucous fibroids classification as score 6, group II, was noted. GnRH analogue was indicated for 3 months before intervention to treat anaemia. The patient was submitted to hysteroscopic myomectomy with direct mobilisation technique, with the fibroid completely removed without complications in a surgery which lasted for 52 min and 20 s. © 2008 Springer-Verlag.

Avaliação histeroscópica em pacientes com infertilidade

PURPOSE: to describe hysteroscopy findings in infertile patients. METHODS: this was a retrospective series of 953 patients with diagnosis of infertility evaluated by hysteroscopy. A total of 957 patients investigated for infertility were subjected to hysteroscopy, preferentially during the first phase of the menstrual cycle. When necessary, directed biopsies (under direct visualization during the exam) or guided biopsies were obtained using a Novak curette after defining the site to be biopsied during the hysteroscopic examination. Outcome frequencies were determined as percentages, and the χ2 test was used for the correlations. The statistical software EpiInfo 2000 (CDC) was used for data analysis. RESULTS: a normal uterine cavity was detected in 436 cases (45.8%). This was the most frequent diagnosis for women with primary infertility and for women with one or no abortion (p<0.05). Abnormal findings were obtained in 517 of 953 cases (54.2%), including intrauterine synechiae in 185 patients (19.4%), endometrial polyps in 115 (12.1%), endocervical polyps in 66 (6.0%), submucosal myomas in 47 (4.9%), endometrial hyperplasia in 39 (4.1%), adenomyosis in five (0.5%), endometritis (with histopathological confirmation) in four (0.4%), endometrial bone metaplasia in two (0.4%), and cancer of the endometrium in one case (0.1%). Morphological and functional changes of the uterus were detected in 5.6% of the cases, including uterine malformations in 32 (3.4%) and isthmus-cervical incompetence in 21 (2.2%). CONCLUSIONS: intrauterine synechiae were the most frequent abnormal findings in patients evaluated for infertility. Patients with a history of abortion and infertility should be submitted to hysteroscopy in order to rule out intrauterine synechiae as a possible cause of infertility.

Acurácia da histerossonografia versus ultrassonografia transvaginal em mulheres inférteis candidatas às técnicas de reprodução assistida

PURPOSE: To compare the diagnostic accuracy of sonohysterography (HSN) and conventional transvaginal ultrasound (USG) in assessing the uterine cavity of infertile women candidate to assisted reproduction techniques (ART). METHODS: Comparative cross-sectional study with 120 infertile women candidate to ART, assisted at Centro de Reprodução Assistida (CRA) of Hospital Regional da Asa Sul (HRAS), Brasília-DF, from August 2009 to November 2010. Sonohysterography was performed with saline solution infusion in a close system. The sonohysterography finding was compared to previous USG results. The uterine cavity was considered abnormal whenthe endometrium was found to be thicker than expectedduring the menstrual cycle and whenan endometrial polyp, a submucous myoma and an abnormal shape of the uterine cavity were observed. The statistical analysis was doneusing absolute frequencies, percentage values and the χ 2, with the level of significance set at5%. RESULTS:HSN revealed that 92 (76.7%) infertile women candidate to ARThad anormal uterine cavity, while 28 (23.3%) had the following abnormalities: 15 polyps (12.5%).
