Manejo de las lesiones anexiales en el embarazo y actualización del abordaje laparoscópico / Management of adnexal masses in pregnancy and an update of the laparoscopic approach

Resumen El manejo del tumor anexial en embarazadas sigue siendo un desafío. El objetivo del siguiente trabajo es realizar una revisión bibliográfica, en la que se abordarán las diferentes alternativas en cuanto a diagnóstico y manejo del tumor anexial en embarazadas, así como también indicaciones de abordaje quirúrgico y recomendaciones para una cirugía segura. Los tumores anexiales en embarazadas son poco frecuentes, y la mayoría son benignos y tipo funcionales. La ecografía ha sido fundamental para lograr diferenciar su carácter benigno o maligno. El manejo puede ser expectante o quirúrgico. El manejo quirúrgico se reserva para ciertas características de las lesiones anexiales. En cuanto a la vía operatoria, la literatura apoya la laparoscopia mostrando que existen múltiples beneficios al compararla con la laparotomía. Para el abordaje quirúrgico existen opciones en cuanto a la técnica, siendo estas anexectomía o quistectomía. Resulta fundamental tener consideraciones especiales en la técnica debido a los cambios fisiológicos de las embarazadas, como por ejemplo la altura uterina y el tamaño del tumor anexial. A modo de conclusión, el manejo de los tumores anexiales en el embarazo sigue siendo controversial y se extrapola principalmente basándose en la literatura de pacientes no gestantes u otros procedimientos quirúrgicos en embarazadas.

Abstract Nowadays the management of the adnexal tumors in pregnant women is still a challenge. The purpose of this article is to perform a bibliographic review and present the differential diagnosis, management, and surgical approaches for the women in this condition. Adnexal tumors in pregnant women are rare, most of them are benign corresponding to functional cysts. In order to differentiate benign from malignant tumors, Ultrasonography has been one of the most important imaging advances. The management can be either expectant or surgical. Surgical management is referred for tumors with certain specific characteristics. In relation to surgical management, the literature supports laparoscopy, showing greater benefits in comparison to laparotomy. There are different options for this kind of approach. Its mandatory to have special considerations in the technique due to the physiological changes in pregnant women, some examples are the uterine and the tumor size. The management of the adnexal tumors in pregnancy is still controversial, its based on studies of non-pregnant patients or other kinds of surgeries in pregnant women.

Curva de aprendizaje para el diagnóstico ecográfico específico de masas anexiales / Learning curve for the specific ultrasound diagnosis of adnexal masses

OBJETIVO: Determinar el tiempo que requiere una curva de aprendizaje para diagnóstico ecográfico específico histopatológico en masas anexiales basándonos en cálculos estadísticos no influidos por la prevalencia según diferentes grados de experiencia. MÉTODOS: Estudio observacional, descriptivo, transversal. Se estudiaron imágenes de 108 masas anexiales. La prueba estándar de oro fue el reporte histopatológico definitivo. Se comparó el rendimiento diagnóstico de 4 examinadores con la siguiente experiencia en diagnóstico ecográfico de patología anexial: A > 20 años, B ≤ 20 hasta > 10 años, C ≤ 10 hasta > 5 años y D ≤ 5 años, analizando solo imágenes y sin datos clínicos de las pacientes, para emitir un diagnóstico específico a libre escritura. RESULTADOS: Prevalencia de masas malignas 17,2 % (15/87). Nivel de confianza en los examinadores se consideró según falta de respuesta diagnóstica: alto (<6 %) con experiencia de más de 10 años y moderado a bajo ≤ 10 años. Examinadores con más de 5 años siempre mostraron likelihood ratio positivo mayor a 10, exactitud diagnóstica mayor a 90 % y Odds ratio diagnóstica mayor a 46, no así para examinador con menor tiempo de experiencia, quién presentó resultados con mala utilidad clínica. El cambio de probabilidad de acierto específico pre-test a post-test mejoró consistentemente con los años de experiencia. CONCLUSIÓN: Se necesitarían más de 10 años de experiencia con especial dedicación a ecografía ginecológica avanzada para un rendimiento diagnóstico específico deseado junto con alta confianza en ecografía de masas anexiales.

OBJECTIVE: To determine the time required for a learning curve of histopathological specific ultrasound diagnosis in adnexal masses based on statistical calculations not influenced by prevalence according to different degrees of experience. METHODS: Observational, descriptive, cross-sectional study. Images of 108 adnexal masses were studied. The gold standard test was the definitive histopathological report. The diagnostic performance of 4 examiners with the following experience in ultrasound diagnosis of adnexal pathology: A > 20 years, B ≤ 20 to > 10 years, C ≤ 10 to > 5 years and D ≤ 5 years was compared, analyzing only images and blinded of clinical data of the patients, to issue a specific diagnosis with free writing. RESULTS: Prevalence of malignant masses 17.2% (15/87). The level of confidence in the examiners was considered according to the lack of diagnostic response: high (<6%) with experience of more than 10 years and moderate to low ≤ 10 years. The examiners with more than 5 years always showed likelihood ratio positive greater than 10, diagnostic accuracy greater than 90% and diagnostic Odds ratio greater than 46, not so for the examiner with less experience time who presented results with little clinical utility. The change in specific probability from pre-test to post-test improved consistently with years of experience. CONCLUSION: More than 10 years of experience with special dedication to advanced gynecological ultrasound are probably needed for a desired specific diagnostic performance coupled with high confidence in adnexal mass ultrasound.

Massas anexiais: descrição e interpretação ultrassonográfica por IOTA / Adnexal masses: IOTA ultrasound description and interpretation

Este artigo visa apresentar ao médico ginecologista (clínico e/ou cirurgião), de forma prática, a normatização internacional da prática da ultrassonografia ginecológica para avaliação das massas anexiais. Desde 2000, o grupo europeu IOTA (International Ovarian Tumor Analysis) vem colhendo dados e difundindo conhecimento nessa área, de forma a padronizar o exame ultrassonográfico. Quais descritores ecográficos devem ser valorizados, como devem ser descritos e medidos, como aplicar o estudo Doppler e como interpretar a presença ou ausência desses descritores ecográficos na diferenciação das massas anexiais benignas de malignas, inferindo o risco de malignidade das massas, tudo isso está bem definido.(AU)

The main aim of this article is to present to gynecologists (clinicians and/or surgeons) the practical international gynecological ultrasound standardization for adnexal masses assessment. Since 2000, European group IOTA (International Ovarian Tumor Analysis) has been collecting data and disseminating knowledge in order to standardize ultrasound examination. It is already well-defined which ultrasound features should be described and measured, how power/color Doppler have to be applied and how the presence or absence of these features can differentiate benign from malign masses, inferring tumors malignancy risk.(AU)

GIRADS: método de clasificación de masas anexiales, revisión sistemática y metanálisis. 10 años de experiencia / GIRADS: adnexal masses classification method, systematic review and metanalysis. 10 years of experience

OBJETIVO: evaluar la experiencia en la utilización del método GIRADS para clasificar masas anexiales a diez años de su primera publicación. MÉTODO: Se realizó búsqueda de estudios que utilizan el sistema GIRADS: Medline (Pubmed), Google Scholar y Web of Science, desde enero de 2009 hasta diciembre de 2019. Se calculó la sensibilidad y especificidad agrupada, Likelihood ratio (LR) (+) y LR (-) y Odds ratio de diagnóstico (DOR). La calidad de los estudios se evaluó con QUADAS-2. RESULTADOS: Se identificaron 15 estudios y se incluyeron 13 de ellos con 4473 masas, 878 de ellas malignas. La prevalencia media de malignidad ovárica fue del 23 % y la agrupada de 19.6%. El riesgo de sesgo fue alto en cuatro estudios para el dominio "selección de pacientes" y fue bajo en todos en todos los estudios para los dominios "prueba índice" y "prueba de referencia". La sensibilidad, especificidad, LR (+) y LR (-) agrupadas y el DOR del sistema GIRADS para clasificar las masas anexiales fueron: 96.8% (intervalo de confianza [IC] 95% = 94% - 98%), 91.2 % (IC 95 % = 85% - 94%), 11.0 (IC 95% = 6.9 -13.4) y 0.035 (IC 95% = 0.02- 0.09), y 209 (IC 95% = 99-444), respectivamente. La heterogeneidad fue alta para la sensibilidad y especificidad. De acuerdo a la metaregresión, la heterogeneidad entre los estudios se explica por la prevalencia de malignidad, múltiples observadores y la ausencia de diagnóstico histopatológico para todos los casos incluidos en un determinado estudio. CONCLUSIÓN: el sistema GIRADS tiene un buen rendimiento diagnóstico para clasificar masas anexiales.

OBJECTIVE: to evaluate the experience of using GIRADS method to classify adnexal masses ten years after its publication. METHOD: A search was carried out for studies reporting on the use of the GIRADS system in the Medline (Pubmed), Google Scholar and Web of Science databases, from January 2009 to December 2019. Pooled sensitivity and specificity, Likelihood ratio (LR) (+) and LR (-) and Diagnostic Odds ratio (DOR) were calculated. The quality of the studies was assessed by QUADAS-2. RESULTS: 15 studies were identified, and 13 of them were included with 4473 masses, of which 878 were malignant. The mean prevalence of ovarian malignancy was 23% and the prevalence pooled. of 19.6%. The risk of bias was high in four studies for the domain 'patient selection' and low for all studies for the domains 'index test' and 'reference test'. The sensitivity, specificity, pooled LR (+) and LR (-) and the DOR of the GIRADS system to classify adnexal masses were 96.8% (95% confidence interval [CI] = 94% -98%), 91.2 % (95% CI = 85% -94%), 11.0 (95% CI = 6.9-13.4) and 0.035 (95% CI = 0.02-0.09), and 209 (95% CI = 99-444), respectively. Heterogeneity was high for both sensitivity and specificity. According to meta-regression, this heterogeneity was explained by the prevalence of malignancy, the use of multiple observers, and the absence of histopathological diagnosis for all cases included in a given study. CONCLUSION: the GIRADS system has a good diagnostic performance to classify adnexal masses.

Added Value of Using a CT Coronal Reformation to Diagnose Adnexal Torsion

OBJECTIVE: To evaluate the increased value of using coronal reformation of a transverse computed tomography (CT) scan for detecting adnexal torsion. MATERIALS AND METHODS: This study included 106 woman suspected of having adnexal torsion who underwent CT with coronal reformations and subsequent surgical exploration. Two readers independently recorded the CT findings, such as the thickening of a fallopian tube, twisting of the adnexal pedicle, eccentric smooth wall thickening of the torsed adnexal mass, eccentric septal thickening of the torsed adnexal mass, eccentric poor enhancement of the torsed adnexal mass, uterine deviation to the twisted side, ascites or infiltration of pelvic fat, and the overall impression of adnexal torsion with a transverse scan alone or combined with coronal reformation and a transverse scan. The areas under the receiver operating characteristic curves (AUCs), sensitivity, specificity, and positive predictive value were used to compare diagnostic performance. RESULTS: Fifty-two patients were confirmed to have adnexal torsion. The addition of coronal reformations to the transverse scan improved AUCs for readers 1 and 2 from 0.74 and 0.75 to 0.92 and 0.87, respectively, for detecting adnexal torsion (p < 0.001 and p = 0.004, respectively). Sensitivity of CT for detecting twisting of the adnexal pedicle increased significantly for readers 1 and 2 from 0.27 and 0.29 with a transverse scan alone to 0.79 and 0.77 with a combined coronal reformation and a transverse scan, respectively (p < 0.001 and p < 0.001, respectively). CONCLUSION: Use of a coronal reformation with transverse CT images improves detection of adnexal torsion.

Multidetector Computed Tomography for the Assessment of Adnexal Mass: Is Unenhanced CT Scan Necessary?

OBJECTIVE: To compare the diagnostic performance and radiation dose between contrast-enhanced CT (ECT) alone, and combined unenhanced and contrast-enhanced CT (UE + ECT) for the assessment of adnexal mass. MATERIALS AND METHODS: This retrospective study was approved by the Institutional Review Board. A total of 146 consecutive patients (mean age, 41.1 years) who underwent preoperative unenhanced and contrast-enhanced multidetector CT of the pelvis and had adnexal masses found at surgery were included. Two readers independently evaluated the likelihood of adnexal malignancy on a 5-point scale on two different imaging datasets (ECT alone and UE + ECT). The area under the receiver operating characteristic curve (AUC) was used to evaluate diagnostic performance. Radiation dose to patients was calculated by the volume CT dose index (CTDIvol) and the dose length products (DLP) on each dataset. RESULTS: Of the total 178 adnexal masses, 133 masses were benign and 45 masses were malignant. For both readers, there is no significant difference of AUC values between ECT alone and UE + ECT for the detection of adnexal malignancy (reader 1, 0.93 vs. 0.95; reader 2, 0.92 vs. 0.91) (p > 0.05). The mean CTDIvol (12.6 +/- 2.2 mGy) and DLP (641.2 +/- 137.2 mGy) of ECT alone was significantly lower than the mean CTDIvol (21.5 +/- 2.7 mGy) and DLP (923.6 +/- 158.8 mGy) of UE + ECT (p < 0.0001). CONCLUSION: The use of unenhanced CT scan in addition to contrast-enhanced CT scan does not improve the detection of adnexal malignancy, but increases radiation exposure.

Torsión anexial sin patología ovárica en gestante del primer trimestre / Adnexal torsion without ovarian pathology in a pregnant woman in the first trimester

La torsión anexial durante el embarazo es una entidad muy poco frecuente y casi siempre ocurre en el contexto de una masa anexial. Es importante establecer el diagnóstico mediante ecografía y en caso de duda se recomienda la utilización de laparoscopia diagnóstica para realizar el tratamiento lo más precozmente posible.

Adnexal torsion during pregnancy is a rare entity and usually occurs in the context of an increase in the mass of the annex. It is important to establish the diagnosis by ultrasound and in case of doubt we recommend the use of diagnostic laparoscopy for treatment as early as possible.

Masas anexiales y embarazo: un desafío para el ultrasonografista / Adnexal masses and pregnancy: a challenge for the ultrasonographer

Se presentan 5 casos de embarazadas con masas anexiales complejas diagnosticadas entre las 5 y 34 semanas de gestación. Una de ellas tuvo indicación quirúrgica por abdomen agudo secundario a torsión anexial izquierda y cuatro, por sospecha de malignidad, que se confirmó en un caso. Dos pacientes tenían patología anexial benigna y la otra, una pseudo masa secundaria a un proceso inflamatorio pelviano crónico.

Five pregnant patients, with complex adnexal masses diagnosed between 5 and 34 weeks of gestation, are presented. One of them had surgical indication due to an acute abdominal pain, secondary to the torsion of the adnexal mass; and the other four, because of suspected malignancy, which was confirmed in one. Two patients had benign adnexal masses, and the other a pseudo cyst secondary to a cronic inflamatoty pelvic process.

Sonographic morphology scores (SMS) for differentiation between benign and malignant adnexal masses.

OBJECTIVE: To determine the sensitivity and specificity of a scoring system for distinguishing between benign and malignant adnexal masses and to detect threshold scores for prediction of malignant ovarian tumors. STUDY DESIGN: Cross-sectional diagnostic testing. SETTING: Department of Obstetrics and Gynecology, Faculty of Medicine, Chiang Mai University. SUBJECTS: A total 158 patients scheduled for elective surgery due to ovarian tumors at Maharaj Nakorn Chiang Mai Hospital between June 16, 2002 and August 8, 2004 were recruited into the study. METHODS: All patients were sonographically examed within 72 hours before surgery by the same sonographer to evaluate the morphology including wall structure, shadowing, septum, echogenicity and score the tumors. The final diagnosis was based on either pathological or operative findings. MAIN OUTCOME MEASURE: Sensitivity and specificity of the best cut-off score. RESULTS: A score of 5 from the receiver operating characteristic curve was found to be the best cut-off score, giving a sensitivity and a specificity of 85% and 70%, respectively. CONCLUSION: Sonographic morphology scores are useful in distinguishing adnexal malignancies from benign lesions in some selected cases.

X-ray diagnosis of salpingian diverticulum--a report of 7 cases / 华中科技大学学报（医学）（英德文版）

Seven cases of typical salpingian diverticulum were identified by hysterosalpinography (HSG). The differentiation diagnosis of the disease was discussed. HSG is believed to be the method of choice for the diagnosis of this disease.

Diagnostic value of transvaginal and color doppler ultrasonography in cases with adnexal masses and abdominal pain: diagnostic tools in emergency room

Over a period of four years, 91 patients presented with abdominal pain and adnexal mass were included in this study. Serum beta subunit human chorionic gonadotrophin [BhCG] values were obtained. The cohort was classified into two groups: Group I with a clinical suspicion of tubal pregnancy [n = 45], all of them had positive results in quantitative BhCG test and Group II with ovarian mass and abdominal pain [n = 46], no one of them had positive BhCG test. Transvaginal sonography [TVS] and color Doppler [CDS] were done. Patients were referred for laparoscopy and/or laparotomy. It was concluded that CDS has a limited value in addition to conventional TVS in diagnosing tubal pregnancy, however it is a good supplementary diagnostic tool for monitoring the viability of trophoblast. On the other hand, CDS is crucial in patients with suspected ovarian torsion for an early and accurate diagnosis to save reproductive organs

The value of ultrasonography in the diagnosis of adnexal masses.

Seventy patients with palpable adnexal masses were subjected to ultrasonographic examination. Three patients with negative ultrasound and no disease were excluded from the final analysis. Correct diagnosis was obtained in 58.2% patients; contributory information in 16.4%. Ultrasonography is valuable in diagnosing functional and benign ovarian neoplasms. It is also useful in suspecting malignant ovarian neoplasms and confirming diagnosis of ectopic pregnancy, if correlated with the clinical findings.
