ABSTRACT

Abstract Objective Gonadotropin-releasing hormone analogues (GnRH-a) have been used preoperatively before hysteroscopic myomectomy to decrease the size and vascularization of the myomas, but evidence to support this practice is weak. Our objective was to analyze the use of GnRH-a in the reduction of submucous fibroid as a facilitator for surgical hysteroscopy from published clinical trials. Data sources Studies from electronic databases (Pubmed, Scielo, EMBASE, Scopus, PROSPERO), published between 1980 and December 2018. The keywords used were fibroid, GnRH analogue, submucous, histeroscopy, histeroscopic resection and their correspondents in Portuguese. Study selection The inclusion criteria were controlled trials that evaluated the GnRH-a treatment before hysteroscopic resection of submucous myomas. Four clinical trials were included in the meta-analysis. Data collection Two review authors extracted the data without modification of the original data, using the agreed form. We resolved discrepancies through discussion or, if required, we consulted a third person. Data synthesis The present meta-analysis included a total of 213 women and showed no statistically significant differences in the use of GnRH-a compared with the control group for complete resection of submucous myoma (relative risk [RR]: 0.94; 95%; confidence interval [CI]: 0.80-1.11); operative time (mean difference [MD]: - 3.81; 95%;CI : - 3.81-2.13); fluid absorption (MD: - 65.90; 95%;CI: - 9.75-2.13); or complications (RR 0.92; 95%;CI: 0.18-4.82). Conclusion The present review did not support the routine preoperative use of GnRH-a prior to hysteroscopic myomectomy. However, it is not possible to determine its inferiority when compared with the other methods due to the heterogeneity of existing studies and the small sample size.


Resumo Objetivo Análogos de hormônio liberador de gonadotrofina (GnRH-a) têm sido usados no pré-operatório de miomectomia histeroscópica para reduzir o tamanho e vascularização dos miomas, mas a evidência que suporta essa prática é fraca. Nosso objetivo foi analisar o uso de GnRH-a na redução do mioma submucoso como um facilitador de histeroscopia cirúrgica em ensaios clínicos publicados. Fonte de dados Estudos de bases de dados eletrônicas (Pubmed, Scielo, EMBASE, Scopus, PROSPERO), publicados entre 1980 e dezembro de 2018. As palavras-chave usadas foram fibroid, GnRH analogue, submucous, histeroscopy, histeroscopic resection e seus correspondentes em português. Seleção dos estudos Os critérios de inclusão foram ensaios clínicos controlados que avaliaram o tratamento com GnRH-a antes da ressecção histeroscópica de miomas submucosos. Quatro ensaios clínicos foram incluídos na meta-análise Coleta de dados Dois autores revisores extraíram os dados, sem modificarem os dados originais, usando a forma acordada. Nós resolvemos as discrepâncias através de discussão ou, se necessário, consultando um terceiro autor. Síntese dos dados A meta-análise incluiu um total de 213 mulheres e não demonstrou diferença estatisticamente significativa no uso de GnRH-a comparado com o grupo controle para ressecção completa de mioma submucoso (risco relativo [RR]: 0.94. índice de confiança [IC] 95%;: 0.80-1.11); tempo cirúrgico (diferença de média [MD]: - 3.81; IC95%;: -3.81-2.13); absorção de fluidos (MD: - 65.90; IC95%;: - 9.75-2.13); ou complicações (RR 0.92; IC95%;: 0.18-4.82). Conclusão A presente revisão sistemática não suporta o uso pré-operatório rotineiro de GnRH-a antes de miomectomia histeroscópica. No entanto, não é possível determinar sua inferioridade quando comparado aos outros métodos devido à heterogeneidade dos estudos existentes e ao pequeno tamanho da amostra.

ABSTRACT

Las malformaciones uterinas congénitas presentan una baja prevalencia en la población general (0,5-6,7 por ciento), el útero septo es la más frecuente. Estas enfermedades pueden afectar a los resultados reproductivos de las pacientes, así como aumentar la incidencia de abortos de repetición, presentaciones fetales anómalas o partos pretérminos. De la misma forma, los miomas uterinos submucosos también pueden producir alteraciones de la fertilidad, aunque la sintomatología más relacionada con los mismos es el sangrado. Constituyen el tumor benigno más frecuente del aparato genital femenino. El diagnóstico de estas patologías puede realizarse mediante pruebas de imagen como la ecografía transvaginal y la resonancia magnética, aunque la visualización directa vía histeroscópica sigue siendo de elección. Esta técnica constituye, además, la primera opción terapéutica, ya que se puede realizar tanto la resección del septo uterino como la miomectomía, sin apenas complicaciones y mediante una técnica quirúrgica segura y poco invasiva. El tratamiento histeroscópico está especialmente indicado en pacientes sintomáticas, con esterilidad o abortos de repetición, incluso antes de iniciar terapias de reproducción asistida. En el siguiente trabajo exponemos el caso de una paciente que presentaba un septo uterino constituido en su mayor parte por un leiomioma submucoso tratado vía histeroscópica; siendo un caso muy raro, dada la infrecuente asociación entre ambas patologías(AU)


Congenital uterine malformations present low prevalence in the general population (0.5-6.7 percent), and uterus septum is the most frequent. These pathologies can affect the reproductive outcomes of patients, as well as increase the incidence of repeating abortions, abnormal fetal presentations or preterm deliveries. In the same way, submucosal uterine fibroids can also produce alterations in fertility, although the most related symptomatology is bleeding. They are the most frequent benign tumor of the female genital tract. Diagnosis can be carried out through imaging tests such as transvaginal ultrasound and magnetic resonance imaging, although direct visualization, via hysteroscopy, is still the preferred option. This technique is also the first therapeutic option, since both, resection of the uterine septum and myomectomy can be performed with few complications and a safe and minimally invasive surgical technique. Hysteroscopy is especially indicated in symptomatic patients, with sterility or repeated abortions, even before initiating assisted reproduction therapies. In the following paper, we present the case of a patient who presented a uterine septum formed mostly by a submucosal leiomyoma. She was treated by hysteroscopy. This case is very rare given the infrequent association between both pathologies(AU)

ABSTRACT

El dolor torácico es un motivo frecuente de consulta en los servicios de urgencias, sin embargo, el hematoma esofágico es una causa muy poco frecuente. Se manifiesta más frecuentemente en mujeres de edad media y avanzada, con una triada de dolor torácico súbito, disfagia u odinofagia y hematemesis. Presentamos un caso de una mujer de 89 años con antecedentes de hipertensión arterial en tratamiento, usuaria de antihipertensivos y aspirina, con una historia de dos días de evolución de dolor retroesternal, sensación febril, disnea y tos productiva secundario a un hematoma esofágico.


Thoracic pain is a frequent reason for consultation in the emergency department, however, esophageal hematoma is a very rare cause. It manifests more commonly in women of middle and advanced age, with a triad of sudden chest pain, dysphagia or odynophagia and hematemesis. We present a case of a 89 years old female patient, with a history of arterial hypertension in treatment, user of antihypertensive drugs and aspirin with a two day history of retrosternal pain, febrile sensation, dyspnea and productive cough due to a esophageal hematoma.

ABSTRACT

Resumen Introducción Los tumores submucosos del tracto gastrointestinal alto tienen potencial de malignidad y también pueden ser una carga para el paciente, por lo que se requiere disponer de un tratamiento seguro y eficaz. El surgimiento de la técnica de resección endoscópica por tunelización submucosa (STER) en los últimos años ha mostrado resultados prometedores. Caso clínico Se presenta el caso de un hombre de 47 años asintomático, en quien, en el contexto de un estudio preoperatorio de cirugía bariátrica, se pesquisa una lesión subepitelial en la unión gastroesofágica. La endosonografía alta es compatible con un leiomioma esofágico. Se realiza STER con éxito y sin complicaciones; a las 48 h es dado de alta. El estudio histopatológico confirmó un leiomioma esofágico. Discusión La técnica STER ha demostrado consistentemente ser segura y eficaz en el tratamiento de los tumores submucosos de la unión gastroesofágica. El desafío es difundir la técnica por el resto del país, para mayor beneficio de los pacientes.


Introduction Upper gastrointestinal submucosal tumors are potentially malignant lesions; so safe and efficient treatments are needed. In recent years, submucosal tunneling endoscopic resection (STER) has emerged as a novel therapeutic technique, with promising results. Case report 47-year-old male patient, previously asymptomatic, who was found to have a subepithelial lesion at the gastroesophageal junction. Upper endoscopic ultrasound was compatible with a leiomyoma. He underwent STER to remove the tumor and recovered with any complications. The biopsy confirmed an esophageal leiomyoma. Discussion STER has become a highly feasible and safe therapeutic option for submucosal tumors of the gastroesophageal junction. The challenge is to spread knowledge about this technique, to maximize patient's benefit.

ABSTRACT

Abstract Objective To evaluate the accuracy of transvaginal ultrasonography, hysteroscopy and uterine curettage in the diagnosis of endometrial polyp, submucous myoma and endometrial hyperplasia, using as gold standard the histopathological analysis of biopsy samples obtained during hysteroscopy or uterine curettage. Methods Cross-sectional study performed at the Hospital Universitário de Brasília (HUB). Data were obtained from the charts of patients submitted to hysteroscopy or uterine curettage in the period from July 2007 to July 2012. Results One-hundred and ninety-one patients were evaluated, 134 of whom underwent hysteroscopy, and 57, uterine curettage. Hysteroscopy revealed a diagnostic accuracy higher than 90% for all the diseases evaluated, while transvaginal ultrasonography showed an accuracy of 65.9% for polyps, 78.1% for myoma and 63.2% for endometrial hyperplasia. Within the 57 patients submitted to uterine curettage, there was an accuracy of 56% for polyps and 54.6% for endometrial hyperplasia. Conclusion Ideally, after initial investigation with transvaginal ultrasonography, guided biopsy of the lesion should be performed by hysteroscopy, whenever necessary, in order to improve the diagnostic accuracy and subsequent clinical management.


Resumo Objetivo avaliar a acurácia da ultrassonografia transvaginal, da histeroscopia e da curetagem uterina no diagnóstico de pólipo endometrial, mioma submucoso e hiperplasia de endométrio, utilizando como padrão-ouro a análise histopatológica de amostras obtidas por biópsia realizada durante a histeroscopia ou a curetagem. Métodos estudo transversal realizado no Hospital Universitário de Brasília (HUB), cujas informações foram obtidas nos prontuários das pacientes que foram submetidas à histeroscopia ou curetagem uterina no período de julho de 2007 a julho de 2012. Resultados Foram avaliadas 191 pacientes, sendo que 134 foram submetidas à histeroscopia e 57 à curetagem uterina. Observou-se acurácia diagnóstica maior que 90% para todas as patologias avaliadas por histeroscopia, enquanto que por ultrassonografia transvaginal observou-se acurácia de 65,9% para pólipo, 78,1% para mioma e 63,2% para hiperplasia endometrial. Nas 57 pacientes submetidas a curetagem uterina, observou-se acurácia de 56% para pólipo e de 54,6% para hiperplasia endometrial. Conclusão Idealmente, após a investigação inicial com ultrassonografia transvaginal, deveria, sempre que necessário, ser realizada histeroscopia com biópsia guiada da lesão, o que melhoraria a acurácia diagnóstica e posterior conduta clínica.

ABSTRACT

Objetivo: presentar una técnica quirúrgica para la resección de miomas submucosos de gran tamaño por vía histeroscópica. Materiales y métodos: reportamos el caso de una paciente con dos miomas submucosos de gran tamaño, con componente intramiometrial, que fue sometida a miomectomía histeroscópica en la Clínica SOMA, centro de alta complejidad, ubicado en Medellín, Colombia. Se presenta una técnica de miomectomía por histeroscopia con el uso del resectoscopio para disminución del volumen tumoral acompañado de disección roma para crear un plano de clivaje adecuado para la enucleación y extracción completa del tumor. Conclusión: la técnica que combina el uso de la resectoscopia con la enucleación del mioma permitiría la resección de tumores de gran tamaño con menor tiempo quirúrgico, un menor gasto de glicina y, por ende, menor riesgo de intoxicación hídrica y de perforaciones.


Objective: To present a surgical technique for excising large submucosal fibroids using histeroscopy. Materials and methods: We report the case of a patient with two large submucosal fibroids with intramyometrial component, undergoing hysteroscopic myomectomy at Clínica SOMA, a high-complexity institution in Medellin, Colombia. We present a hysteroscopic myomectomy technique using the resectoscope for tumor volume reduction, and the use of a dissection technique that allows to create an adequate cleavage plane for complete tumor removal. Conclusion: A technique combining the use of resectoscopy with fibroid enucleation would allow to resect large tumors with shorter operating time, lower glycine use and, consequently, a lower risk of fluid toxicity and perforations.

ABSTRACT

O esôfago é o local mais comum de tumor de células granulares de origem no trato gastrintestinal. Cerca de 270 casos de tumores de células granulares do esôfago têm sido relatados na literatura. A maioria é encontrada incidentalmente durante a endoscopia. Apesar de ser reconhecido facilmente por suas características endoscópicas, tem que ser diferenciado de outras lesões benignas e malignas da mucosa e submucosa. A maioria dos tumores de células granulares é assintomática e benigna, e o acompanhamento endoscópico pode ser considerado suficiente como manejo terapêutico. Novas opções terapêuticas devem ser consideradas especialmente para lesões maiores. Três casos são relatados de paciente com tumores de células granulares de esôfago inferior, diagnosticados por endoscopia digestiva alta.


The esophagus is the most common site of origin of gastrointestinal tract granular cell tumors. Approximately 270 cases of esophageal granular cell tumors have been reported in the literature. Most esophageal granular cell tumors are found incidentally during endoscopy. Although granular cell tumor of the esophagus has become easily recognizable by its endoscopic features, it has to be differentiated from other benign and malignant mucosal and submucosal lesions. The majority of esophageal granular cell tumors are asymptomatic and benign; thus, close follow-up of the patients with endoscopy could be considered sufficient as a therapeutic management. New therapeutic options should be considered especially for larger lesions. Three cases of granular cell tumors with complaints of epigastric discomfort, regurgitation, nausea, and vomiting, which were detected in the lower part of the esophagus on upper gastrointestinal tract endoscopy, are discussed.

ABSTRACT

OBJECTIVE: To study the aging of submucous plexus of the small intestine (jejunum-ileum) of the guinea pigs from the quantitative, structural and ultrastructural perspective. METHOD: Chemical preparations of membrane of the jejunum-ileum of old and young animals with the use of light and electronic microscope. RESULTS: The ganglia of young animals presented between 1 and 56 neurons and the old animals presented from 1 to 30 neurons. The mean density of the ganglia by cm² in the young jejunum-ileum was of 551±36.89 and in the old one 413±11.86. The density of the neurons was 5011±291.11 neurons/cm² average in young animals and 2918±120.70 neurons/cm² in the old ones. The size of the neurons varied in both age groups. The collagen fibers in the ganglia of old animals they were condensed. Degenerated mitochondrias in the interior of the cell were frequent in the old animals. CONCLUSION: In submucous plexus of the jejunum-ileum there is a loss of 38 percent of the neurons with aging.


OBJETIVO: Estudar o envelhecimento do plexo submucoso do intestino delgado (jejuno-íleo) das cobaias do ponto de vista quantitativo, estrutural e ultra-estrutural. MÉTODO: Preparados de membrana do jejuno-íleo de animais jovens e velhos com a utilização de microscopia de luz e eletrônica. RESULTADOS: Os gânglios de animais jovens apresentaram entre 1 e 56 neurônios e os animais velhos apresentaram de 1 a 30 neurônios. A densidade média dos gânglios por cm² no jejuno-íleo jovem foi de 551±36,89 e no velho foi de 413±11,86. A densidade dos neurônios foi de 5011±291,11 neurônios/cm² em média nos animais jovens e 2918±120,70 neurônios/cm² nos velhos. O tamanho dos neurônios variou em ambos os grupos etários. As fibras colágenas nos gânglios de animais velhos estavam mais condensadas. Mitocôndrias degeneradas no interior da célula foram freqüentes nos animais velhos. CONCLUSÃO: No plexo submucoso do jejuno-íleo há uma perda de 38 por cento dos neurônios com o envelhecimento.

ABSTRACT

Los tumores estromales del tracto gastrointestinal (GIST), aunque infrecuentes, son tumores mesenquimatosos importantes de origen mesodérmico. Macroscópicamente se presentan como una masa intramural submucosal, siendo los mas comunes dentro de los tumores mesenquimatosos. La forma maligna, típicamente agresiva y resistente al tratamiento, es afortunadamente rara. Un importante avance ha sido la caracterización del marcador oncogénico KIT y su relación a la patogénesis del Tumor Estromal Gastrointestinal. Sin embargo, recientes investigaciones han demostrado la génesis de los GIST que son KIT negativos. Por lo tanto, la positividad del marcador oncogénico KIT, si bien es altamente sensible, no es requerimiento indispensable para el diagnóstico de GIST. Presentamos nuestra paciente con un GIST del intestino delgado y negatividad al c-KIT(CD 117).


Gastrointestinal stromal tumors (GIST) are uncommon but important mesenchymal tumors of the Gastrointestinal Tract, defined as being of mesodermal origin. Macroscopically they present as intramural submucosal masses, being the most common mesenchymal tumors to arise from the gastrointestinal tract. The malignant form, typically aggressive and resistant to treatment, in fortunately rare. An important development has been the characterization of the oncogene marker KIT, and its relation to the pathogenesis of GIST. However recent research has shed light on the genesis of GIST that is KIT negative. KIT is highly sensitive for GIST (though not 100%) but is not a marker of malignancy or essential requirement to the diagnosis of GIST. We show a patient with a GIST of the small intestine, KIT- negative.
