Abstract Introduction: leiomyomas are benign mesenchymal tumors of smooth muscle origin that can develop in various locations. Urethral leiomyomas are rare, with approximately only 120 cases reported in the literature. These tumors often occur in the third and fourth decades of life but are rare in menopausal patients. In general, treatment involves surgery, only three recurrence reports in the literature. Description: a case report on a 56-year-old woman; the patient had type II diabetes mellitus and chronic high blood pressure, was overweight (body mass index, 27.1 kg/m2), and a smoker. Besides this, the patient presented symptoms of urinary obstruction and had a large urethral leiomyoma. The tumor was completely removed with no associated urethral lesions using a complex, combined abdominalvaginal surgical approach. Discussion: the management and treatment on urethral leiomyomas is challenging and have not been established yet due to the rarity of these tumors.

Resumo Introdução: os leiomiomas são tumores mesenquimais benignos de origem muscular lisa, podendo manifestar-se em diversas localizações. Os leiomiomas uretrais são raros, tendo apenas aproximadamente 120 casos relatados na literatura. São mais comuns na terceira e quarta décadas de vida, sendo raros em pacientes menopausadas. Em geral, são tratados cirurgicamente, com apenas três relatos de recidivas na literatura. Descrição: relato de caso de uma paciente do sexo feminino, 56 anos, portadora de diabetes mellitus do tipo II, hipertensão arterial crônica, sobrepeso (IMC 27,1Kg/m2) e tabagismo. Além disso, com quadro de sintomas obstrutivos urinários e portadora de um grande leiomioma uretral, este que foi completamente removido, através de uma desafiadora abordagem cirúrgica combinada (abdominal e vaginal), sem lesões uretrais associadas. Discussão: os leiomiomas uretrais são tumores raros e seu manejo é desafiador e ainda não foi estabelecido.

We report a case of giant hysteromyoma and complex pelvic adhesion treated by robotic assisted laparoscopic total hysterectomy and bilateral salpingectomy. The patient was diagnosed with uterine fibroids after physical examination in 1998 but did not receive any treatment, and regular examinations reported progressive growth of the fibroids. Ultrasound suggested multiple uterine fibroids, and pelvic MRI indicated large uterine fibroids with bleeding. Robot-assisted laparoscopic total hysterectomy and bilateral salpingectomy were performed after relevant examinations, and the operation was completed smoothly. The patient was discharged 4 days after surgery with good appearance of the abdominal wall and good recovery during the follow-up. With its unique advantages, robot-assisted laparoscopy provides a minimally invasive surgical approach for giant hysterectomy with complex pelvic adhesions.

Introducción: Los leiomiomas uterinos son los tumores pélvicos benignos más comunes entre las mujeres. Se estima que 60% de las mujeres llegan a tener miomatosis a lo largo de la vida (1). La necesidad de tratamiento médico y/o quirúrgico es muy importante de evaluar, ya que los fibromas son una fuente importante de morbilidad ginecológica. Objetivos: Describir el caso de un gran mioma uterino con manejo prequirúrgico de análogos de GnRH, analizando los hallazgos obtenidos en el caso según la evidencia actual. Discusión: Se reporta el caso de una mujer de 29 años sin antecedentes mórbidos conocidos, con presencia de una gran masa abdominal, motivo por el cual se realizó una ecotomografía abdominal que evidenció una masa sugerente de un gran mioma uterino subseroso. Se realizó miomectomía vía laparotomía previo tratamiento médico con análogos de GnRH. Actualmente la frecuencia de miomas de gran tamaño es poco frecuente, por lo que se busca discutir el impacto del tratamiento médico previo a la cirugía en mujeres jóvenes. Conclusiones: La experiencia con el uso prequirúrgico de agonistas de GnRH indica una ventaja en el trabajo bien definida y su uso como tratamiento coadyuvante a la cirugía está bien establecido. Sin embargo, se debe tener en cuenta la posibilidad de recurrencia de los miomas

Introduction: Uterine leiomyomas are the most common benign pelvic tumors in women. It is estimated that 60% of women develop myomatosis throughout life (1). The need for medical and / or surgical treatment is very important to assess, since fibroids are an important source of gynecological morbidity. Objectives: To describe the case of a large uterine myoma with presurgical management of GnRH analogues and to summarize updated evidence on their use. Discussion: The case of a 29-year-old woman with no known morbid history is reported, with the presence of a large abdominal mass, which is why an abdominal ultrasound scan was performed, which revealed a mass suggestive of a large subserous uterine myoma. Myomectomy was performed via laparotomy after medical treatment with GnRH analogues. Currently, the frequency of large fibroids is rare, so we seek to discuss the impact of medical treatment prior to surgery in young women. Conclusions: Experience with the presurgical use of GnRH agonists indicates a well-defined treatment advantage and its use as adjunctive treatment to surgery is well established. However, the possibility of recurrence of fibroids should be taken into account

Abstract Uterine leiomyoma is themost prevalent benign type of gynecological tumor. It affects more than 80% of women worldwide and, within this group, more than 50% may be asymptomatic. However, large fibroid volumes may be associated with symptoms of extrinsic compression, and most of the cases do not present atypical cells. We present the case of a 49-year-old woman who underwent a total abdominal hysterectomy of a 13.5-kg uterine leiomyoma with no malignancies at histopathology and review the literature about giant uterine leiomyomas and their clinical repercussion. We concluded that large volumes do not always pose a threat regarding malignancy; however, future molecular studies are needed to investigate giant uterine fibroids.

Resumo Leiomioma uterino é o tumor benigno ginecológico de maior prevalência. Ele afeta mais de 80% das mulheres no mundo e, deste grupo, mais de 50% podem ser assintomáticas. Contudo, miomas de grande volume podem ser associados com sintomas de compressão extrínseca, e a maioria dos casos não apresentam células atípicas. Nós apresentamos o caso de uma mulher de 49 anos que foi submetida a histerectomia total abdominal de um espécime de 13,5 quilos sem malignidades ao exame histopatológico. Também revisamos a literatura sobre leiomiomas uterinos de grande volume e sua repercussão clínica. Concluímos que grandes volumes nem sempre representam um risco relacionado à malignidade; contudo, estudos moleculares futuros são necessários para investigar leiomiomas uterinos gigantes.

Objective: To investigate the safety and feasibility of laparoscopic double-flap technique (Kamikawa) in digestive tract reconstruction after proximal gastrectomy for esophagogastric junction (EGJ) leiomyoma and gastrointestinal stromal tumor (GIST) with the maximum diameter >5 cm. Methods: A descriptive case-series study was used to retrospectively analyze the data of patients with EGJ leiomyoma and GIST undergoing laparoscopic-assisted proximal gastrectomy and double-flap technique (Kamikawa) at the Department of Gastrointestinal Surgery, Guangdong Hospital of Traditional Chinese Medicine from September 2017 to March 2019. All the tumors invaded the cardia dentate line, and the maximum diameter was >5 cm. After the exclusion of patients requiring emergency surgery and complicating with severe cardiopulmonary diseases, a total of 4 patients, including 3 males and 1 female with age of 29-49 years, were included in this study. After laparoscopic-assisted proximal gastrectomy, the residual stomach was pulled out of the abdominal cavity and marked with methylene blue at the proximal end 3~4 cm from the anterior wall of the residual stomach in the shape of "H". The gastric wall plasma muscular layer was cut along the "H" shape, and the space between the submucosa and the muscular layer was separated to both sides along the longitudinal incision line to make the seromuscular flap. The residual stomach was put back into the abdominal cavity. Under laparoscopy, 4 stitches were intermittently sutured at the upside of "H" shape and 4-5 cm from the posterior wall of the esophageal stump. The stump of the esophagus was cut open, and the submucosa and mucosa were cut under the "H" shape to enter the gastric cavity. The posterior wall of the esophageal stump was sutured continuously with the gastric stump mucosa and submucosa under laparoscopy. The anterior wall of the esophageal stump was sutured continuously with the whole layer of the residual stomach. The anterior wall of the stomach was sutured to cover the esophagus. The anterior gastric muscle flap was sutured and embedded in the esophagus to complete the reconstruction of digestive tract. The morbidity of intraoperative complications and postoperative reflux esophagitis and anastomosis-related complications were observed. Results: All the 4 patients completed the operation successfully, and there was no conversion to laparotomy. The median operative time was 239 (192-261) minutes, the median Kamikawa anastomosis time was 149 (102-163) minutes, and the median intraoperative blood loss was 35 (20-200) ml. The abdominal drainage tube and gastric tube were removed, and the fluid diet was resumed on the first day after surgery in all the 4 patients. The median postoperative hospitalization time was 6 (6-8) days. Postoperative pathology revealed 3 leiomyomas and 1 GIST. There were no postoperative complications such as anastomotic leakage or stenosis, and no reflux symptoms were observed. The median follow-up time was 22 (11-29) months after the operation, and no reflux esophagitis occurred in any of the 4 patients by gastroscopy. Conclusion: For >5 cm EGJ leiomyoma or GIST, double-flap technique (Kamikawa) used for digestive tract reconstruction after proximal gastrectomy is safe and feasible.

INTRODUCCIÓN: Los leiomiomas uterinos son el tumor pélvico más frecuente en la mujer, derivan de las células musculares lisas del miometrio y pueden localizarse en cualquiera de las porciones uterinas. Se clasifican según su relación con las diferentes capas del útero mediante la clasificación de la FIGO. Pueden ser asintomáticos o producir síntomas como sangrado, problemas reproductivos o dolor por compresión de estructuras vecinas. El tratamiento puede ser médico o quirúrgico, teniendo dentro de este último grupo, la posibilidad de realizar una miomectomía o una histerectomía total o subtotal. La histerectomía subtotal permite mantener el cérvix uterino, de tal forma que la técnica quirúrgica es más sencilla, sin embargo, requiere de la morcelación de la pieza para su extracción; mientras que la histerectomía total elimina el riesgo de recidiva de la patología uterocervical, aunque precisa de una mayor curva de aprendizaje. CASO CLÍNICO: Presentamos el caso de una paciente de 52 años a la que se le realizó una histerectomía supracervical laparoscópica por miomas. Posteriormente, se objetivó la aparición de un nuevo mioma en el remanente cervical, que requirió de una traquelectomía vía vaginal. CONCLUSIÓN: La histerectomía subtotal laparoscópica en úteros con múltiples miomas puede tener como efecto adverso la recidiva miomatosa en el cérvix o la aparición de miomas parasitarios secundarios a la morcelación uterina no estanca. Además, implica continuar con el cribado para la prevención del cáncer de cérvix uterino.

BACKGROUND: Uterine leiomyomas are the most frequent pelvic tumor in women. They derive from smooth muscle cells of the myometrium and can be in any of the uterine parts. They are classified according to their relationship with the different layers of the uterus by the FIGO classification. Uterine leiomyomas can be asymptomatic or produce symptoms such as compression pain, reproductive problems and metrorrhagia. The treatment can be medical or surgical. Within this last group there is the possibility of performing a myomectomy or a total or subtotal hysterectomy. The subtotal hysterectomy allows the uterine cervix to be maintained and therefore the surgical technique is simpler. However, it requires the morcellation of the piece for its removal. Alternatively, total hysterectomy eliminates the risk of recurrence of uterocervical pathology, but this procedure presents a steeper learning curve. CLINICAL CASE: We present the case of a patient of 52 years who underwent a laparoscopic supracervical hysterectomy for myomas. Subsequently, the appearance of a new myoma in the cervical remnant was observed, which required a vaginal trachelectomy. CONCLUSION: Laparoscopic subtotal hysterectomy in myomatous uterus can have as an adverse effect myomatous recurrence in the cervix or the appearance of parasitic myomas secondary to non-contained uterine morcellation. In addition, it involves continuing screening for the prevention of cervical cancer.

Abstract Objective To evaluate the obstetric outcomes of singleton high-risk pregnancies with a small size uterine fibroid. Methods This retrospective cohort study was conducted among 172 high-risk pregnant women who were followed-up by a single surgeon between 2016 and 2019. Pregnant women with preconceptionally diagnosed small size (< 5 cm) single uterine fibroids (n = 25) were compared with pregnant women without uterine fibroids (n = 147) in terms of obstetric outcomes. Results There was no statistically significant difference between the groups in terms of adverse pregnancy outcomes. The size of the fibroids was increased in 60% of the cases, and the growth percentage of the fibroids was 25% during pregnancy. Intrapartum and short-term complication was not observed in women who underwent cesarean myomectomy. Conclusion Small size uterine fibroids seem to have no adverse effect on pregnancy outcomes even in high-risk pregnancies, and cesarean myomectomy may be safelyperformed in properly selected cases.

RESUMEN Los leiomiomas esofágicos gigantes son neoplasias raras con un curso clínico impreciso; la mayoría se origina en la porción media e inferior del órgano. Para identificar el diagnóstico y tratamiento adecuado se utilizan pruebas de imágenes y endoscópicas. Compartir y divulgar un nuevo reporte de leiomioma esofágico gigante es el propósito de este trabajo, basado en un nuevo caso. El paciente ingresó por disfagia. Las pruebas para el diagnóstico incluyeron radiografía de esófago, estómago y duodeno, endoscopía digestiva superior, tomografía axial computarizada y resonancia magnética nuclear. El paciente se sometió a cirugía mediante toracotomía derecha, se realizó enucleación de un tumor de 10x6x5cm, y se constató integridad de la mucosa. No hubo evidencias de malignidad en el estudio histopatológico. Fue dado de alta ocho días después de cirugía. La toracotomía con enucleación del tumor esofágico es un procedimiento eficaz para tratar a pacientes con leiomioma gigante.

ABSTRACT Giant esophageal leiomyomas are rare neoplasms with an imprecise clinical course; most originate from the middle and lower portion of the organ. Imaging and endoscopic tests are used to identify the proper diagnosis and treatment. The purpose of this work, based on a new case, is to share and disseminate a new report of giant esophageal leiomyoma. The patient was admitted for dysphagia. Diagnostic tests included radiography of the esophagus, stomach, and duodenum, upper digestive endoscopy, computed tomography, and MRI. The patient underwent surgery by right thoracotomy, enucleation of a 10x6x5cm tumor was performed, and the integrity of the mucosa was verified. There was no evidence of malignancy in the histopathological study. He was discharged eight days after surgery. Thoracotomy with enucleation of the esophageal tumor is an effective procedure to treat patients with giant leiomyoma.

RESUMEN: El Leiomioma es una neoplasia benigna originada en el tejido muscular liso por lo que puede manifestarse en cualquier región del cuerpo humano que contenga músculo liso, siendo el sitio más común el útero, la piel y en el tracto gastrointestinal. La escasa cantidad de tejido muscular liso en boca hace que su manifestación oral sea infrecuente, representando solo 0.06 % del total de este tipo de tumores. Los sitios más afectados suelen ser los labios, las mejillas, el paladar, la lengua y encías. Histológicamente se distinguen tres tipos: el Leiomioma Sólido, Angioleiomioma (Vascular) y Leiomioma Epitelioide (Leiomioblastoma). El origen de esta neoplasia en boca suele ser la túnica media de los vasos sanguíneos. El Leiomioma intraóseo suele ser aún menos frecuente, y con un diagnóstico diferencial complejo, con histopatología que en varias ocasiones no suele ser fácil de clasificar. Si bien es definida como un tumor benigno, su manifestación intraósea puede llegar a ser localmente agresiva y con un diagnóstico controversial, debiendo abordarse muchas veces como una neoplasia maligna. El objetivo de este artículo es presentar una revisión de la literatura de esta variante intraósea de Leiomioma situada en mandíbula, sus consideraciones clínicas y un algoritmo de tratamiento.

ABSTRACT: Leiomyoma is a benign neoplasm, the origin is the smooth muscle tissue that can be found in any area of the human body, which contains smooth muscle tissue. The most common regions it can be located, are the uterus, the skin and the gastrointestinal tract. The low quantity of muscle tissue in the mouth leads to infrequent oral manifestation, representing only 0.06 % of these tumors. The most affected regions are the lips, cheeks, palate, tongue and gums. The Histologic classification is: Solid Leiomyoma, Angioleiomyoma (vascular) and Epithelioid Leiomyoma (Leiomyoblastoma). The origin of this tumor in the mouth is the tunica media of the blood vessels. Nevertheless, and in spite of being defined as a benign tumor, it can be extremely aggressive, be subject to controversial diagnosis, and must often be treated as a malign neoplasm. The Intraosseous Leiomyoma is infrequent and presents a complicated differential diagnosis, with a histopathology that many times cannot be easily classified. The aim of this article is to present a review of intraosseous variant Leiomyoma in the mandible, the clinicians´ considerations and a treatment algorithm.

No ano de 2018, aproximadamente 549.000 cirurgias robóticas em ginecologia foram realizadas no mundo, ocupando o segundo lugar em volume de procedimentos. Estudos sugerem superioridade ou equivalência dessa tecnologia em relação à cirurgia laparoscópica, porém o custo, a disponibilidade e o treinamento limitam sua adoção. Nesta revisão narrativa, os principais benefícios e limitações dos procedimentos ginecológicos robóticos foram analisados. O uso de robôs na histerectomia para o tratamento de lesões benignas apresentou menor incidência de lesões iatrogênicas e de sangramentos em relação à laparoscopia convencional. Na miomectomia robótica, além de menor taxa de complicações, maior volume de miomas retirados foi observado. A cirurgia robótica tem sido bem-sucedida para cirurgias de estadiamento no câncer de endométrio em estágios precoces (I e II), devido à menor taxa de complicações em relação à cirurgia aberta e aos resultados satisfatórios obtidos em mulheres obesas. A histerectomia robótica realizada no tratamento de câncer de colo do útero apresentou menor perda sanguínea em parte dos estudos, porém um ensaio clínico recente demonstrou maior mortalidade no grupo dos procedimentos minimamente invasivos. Espera-se que, com a redução dos custos e a ampliação dos treinamentos, a cirurgia robótica seja uma ferramenta complementar às modalidades já existentes.(AU)

In 2018, 549,000 robotic gynecology surgeries were done in the world, ranking second in volume of procedures. Studies suggest the superiority or equivalence of this technology over laparoscopic surgery, but its cost, availability, and training limit its adoption. In this narrative review, the benefits and limitations of robotic gynecological procedures were investigated. Using robots in hysterectomy for the management of benign lesions showed a lower incidence of iatrogenic lesions and bleeding compared to conventional laparoscopy. In robotic myomectomy, besides a lower complication rate, a larger volume of removed fibroids was noted. Robotic surgery has been successful in the early stages (I and II) endometrial cancer staging surgeries, because of the lower complication rate compared to open surgery and the satisfactory results achieved in obese women. Robotic hysterectomy performed in the treatment of cervical cancer showed less blood loss in part of the studies, but a recent clinical trial showed higher mortality in the minimally invasive procedures group. It is desired that with the reduction of costs and the spread of training robotic surgery will be a complementary tool to existing modalities.(AU)

Abstract Objective To evaluate the factors associated with complete myomectomy in a single surgical procedure and the aspects related to the early complications. Methods A cross-sectional study with women with submucous myomas. The dependent variables were the complete myomectomy performed in a single hysteroscopic procedure, and the presence of early complications related to the procedure. Results We identified 338 women who underwent hysteroscopic myomectomy. In 89.05% of the cases, there was a single fibroid to be treated. According to the classification of the International Federation of Gynecology and Obstetrics (Fédération Internationale de Gynécologie et d'Obstétrique, FIGO, in French),most fibroids were of grade 0 (66.96%), followed by grade 1 (20.54%), and grade 2 (12.50%). The myomectomies were complete in 63.31% of the cases, and the factors independently associated with complete myomectomy were the diameter of the largest fibroid (prevalence ratio [PR]: 0.97; 95% confidence interval [95%CI]: 0.96-0.98) and the classification 0 of the fibroid according to the FIGO (PR: 2.04; 95%CI: 1.18-3.52). We observed early complications in 13.01% of the hysteroscopic procedures (4.44% presented excessive bleeding during the procedure, 4.14%, uterine perforation, 2.66%, false route, 1.78%, fluid overload, 0.59%, exploratory laparotomy, and 0.3%, postoperative infection). The only independent factor associated with the occurrence of early complications was incomplete myomectomy (PR: 2.77; 95%CI: 1.43-5.38). Conclusions Our results show that hysteroscopic myomectomy may result in up to 13% of complications, and the chance of complete resection is greater in small and completely intracavitary fibroids; women with larger fibroids and with a high degree of myometrial penetration have a greater chance of developing complications from hysteroscopic myomectomy.

Resumo Objetivo Avaliar os fatores associados a miomectomia por histeroscopia completa em um único procedimento e as suas complicações. Métodos Estudo de corte transversal com mulheres submetidas a histeroscopia para exérese de miomas submucosos. As variáveis dependentes foram a miomectomia completa realizada em um tempo cirúrgico único, e a presença de complicações precoces relacionadas ao procedimento. Resultados Analisamos 338 mulheres que foram submetidas a miomectomia histeroscópica. Em 89,05% dos casos, o mioma a ser tratado era único. Quanto à classificação da Federação Internacional de Ginecologia e Obstetrícia (Fédération Internationale de Gynécologie et d'Obstétrique, FIGO, em francês), a maioria era de grau 0 (66,96%), seguidos pelos graus 1 (20,54%) e 2 (12,50%). As miomectomias foram completas em 63,31% das mulheres, sendo que os fatores independentemente associados à miomectomia completa foram o diâmetro do maior mioma (razão de prevalência [RP]: 0,97; intervalo de confiança de 95% [IC95%]: 0,96-0,98) e a classificação FIGO grau 0 (RP: 2,04; IC95%: 1,18-3,52). Foram observadas complicações precoces em 13,01% dos procedimentos (4,44% apresentaram sangramento excessivo durante o procedimento, 4,14%, perfuração uterina, 2,66%, falso pertuito, 1,78%, intoxicação hídrica, 0,59%, laparotomia exploradora, e 0,3%, infecção pósoperatória). O único fator independentemente associado à ocorrência de complicações precoces foi a realização de miomectomia incompleta (RP: 2,77; IC95%: 1,43-5,38). Conclusão Nossos resultados mostram que as complicações da miomectomia por histeroscopia podem ocorrer em até 13% dos procedimentos. A chance de ressecção completa é maior em miomas pequenos e completamente intracavitários; mulheres com miomas maiores e com maior grau de penetração miometrial têm maiores chances de desenvolver complicações.

SUMMARY Uterine inversion is an uncommon complication of the puerperium and it is an even rarer complication of the non-puerperal period. In this way, uterine inversions are classified into two groups, being of puerperal origin due to obstetric problems and non-puerperal origin due to gynecological problems. In general, a non-puerperal uterine inversion occurs as a possible complication of a sub mucosal leiomyoma, after an expansive process, a dilation of the cervix occurs and thus its protuberance over the vaginal canal.

RESUMO A inversão uterina é uma complicação incomum do puerpério e é uma complicação ainda mais rara do período não puerperal. Dessa forma, as inversões uterinas são classificadas em dois grupos, sendo as de origem puerperal decorrentes de problemas obstétricos e as inversões de origem não puerperal decorrentes de problemas ginecológicos. Em geral, a inversão uterina não puerperal decorre como uma possível complicação de um leiomioma submucoso — após o processo expansivo, ocorre a dilatação do colo uterino e, dessa forma, a sua protusão sobre o canal vaginal.

SUMMARY OBJECTIVE: This study retrospectively reviewed 46 cases of gastric gastrointestinal stromal tumors treated by endoluminal endoscopic full-thickness resection (EFR) microsurgery in our gastrointestinal endoscopy center. We aimed to evaluate the EFR for the treatment of gastric gastrointestinal stromal tumors originating from the muscularis propria. METHODS: A total of 46 patients with gastric gastrointestinal stromal tumors originated from the muscularis propria layer from January 2012 to June 2015 were treated with EFR. The patients were followed up with gastroscope and computed tomography (CT) for evaluation of therapeutic effect and safety. RESULTS: EFR was successfully accomplished to remove all tumors in 46 patients. The mean procedure time was 82.5±39.8min (56-188min). Except in 3 leiomyomas, pathological examination confirmed gastrointestinal stromal tumor (GIST) in 43 cases. None of the patients had occurred bleeding, peritonitis and other complications after EFR. Thereafter, all patients were followed up with gastro-scope after 1, 6,12 months. CONCLUSIONS: EFR is effective and safe for patients with gastric gastrointestinal stromal tumors originated from muscularis propria layer and has the advantage of less invasive treatment and higher tumor resection rate. It should be considered for further application.

RESUMO OBJETIVO: Este estudo revisou retrospectivamente 46 casos de tumores gástricos estromáticos gastrointestinais tratados por microcirurgia endoluminal endoscópica de ressecção completa (EFR) em nosso centro de endoscopia gastrointestinal. Pretendemos avaliar a EFR para o tratamento de tumores gastrointestinais estromáticos originários da muscularis própria. MÉTODOS: Um total de 46 pacientes com tumores gástricos estromáticos gastrointestinais originários da camada muscular própria, de janeiro de 2012 a junho de 2015, foi tratado com EFR. Os pacientes foram acompanhados com gastroscópio e tomografia computadorizada (TC) para avaliação de efeitos terapêuticos e segurança. RESULTADOS: A EFR foi realizada com sucesso para remover todos os tumores em 46 pacientes. O tempo médio de procedimento foi de 82,5±39,8 min (56-188 min). Exceto em três leiomiomas, exame patológico confirmou tumor estromal gastrointestinal (Gist) em 43 casos. Em nenhum paciente ocorreu sangramento, peritonite e outras complicações após EFR. Posteriormente, todos os pacientes foram acompanhados com gastroscópio após um, seis e 12 meses. CONCLUSÕES: A EFR é eficaz e segura para pacientes com tumores gastrointestinais originários da camada muscular própria e tem a vantagem de ser um tratamento menos invasivo e com maior taxa de ressecção tumoral. Deve ser considerada para posterior aplicação.

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 Objective: This article presents the first series of robotic single-port hysterectomy cases performed at a hospital in Brazil. Methods: From November 2014 to October 2016, 11 patients were indicated to undergo, and nine of them were submitted to single-port hysterectomy using da Vinci Single-Site® platform. However, in two patients, due to multiple previous abdominal surgeries, large uterine volume, and/or a uterus with no mobility, a pneumoperitoneum was performed with a Verres needle, and the pelvic cavity was assessed using a 5mm optics endoscope. In these cases, single-port surgery was not recommended; therefore, multiportal robotic access was chosen, and no intercurrent events were reported. Nine single-port cases were operated on by the same surgeon at Hospital Israelita Albert Einstein. Patient data analyzed included age, body mass index, previous surgeries, and clinical diagnosis. Surgical data included operative time, skin incision, report of intraoperative complications, need for conversion to laparotomy, need for transfer to intensive care unit, need for blood transfusion, inadvertent injury to other organs, length of hospital stay, and death. Results: All cases were completed with da Vinci Single-Site® system, with no intercurrent events. Four patients presented with adenomyosis as the surgical indication, two had uterine myoma, one endometrial cancer, one endometrial polyp, and one desquamative inflammatory vaginitis. The mean age of patients was 44 years (range, 40 to 54 years), and body mass index varied between 23.4 and 33.2kg/m2 (mean 26.4). No complications occurred in any of the cases, such as intestinal or bladder injury, bleeding, or the need for a second surgery. All nine procedures were completed with the robotic single-port access, and no patient required a blood transfusion. Conclusion: Although this study merely presented an initial series of patients submitted to robotic single-port surgery, it demonstrated that the method is feasible and safe, suggesting the possible use of this technique in elective hysterectomy and other gynecological procedures in the future, as described in large reference centers of advanced surgery worldwide. Specifically, in gynecological practice, existing evidence on the use of robot-assisted, single-port surgery seems promising, and although it is not indicated in all cases, it should be considered as a surgical option. Nonetheless, further randomized and controlled clinical studies are necessary to establish the preeminence of robot-assisted, single-port surgery versus single-incision and conventional laparoscopy.

RESUMO Objetivo: Apresentar a primeira série de casos de histerectomia usando sistema robótico de portal único (single-port) em hospital no Brasil. Métodos: No período de novembro de 2014 a outubro 2016, de modo inédito no Brasil, 11 pacientes tiveram indicação inicial e 9 delas foram submetidas à histerectomia por portal único, com a plataforma da Vinci Single-Site®. Em duas pacientes, devido a múltiplas cirurgias abdominais prévias, grande volume uterino e/ou útero sem mobilidade, optou-se pela instalação de pneumoperitônio com agulha de Verres e inspeção da cavidade pélvica com ótica de 5mm, constatando-se, nestes casos, não ser viável a cirurgia por single-port, levando-se, assim, à opção pela técnica robótica multiportal, sem intercorrências. Os nove casos single-port foram operados por um mesmo cirurgião, no Hospital Israelita Albert Einstein. Os dados analisados das pacientes foram idade, índice de massa corporal, cirurgias anteriores e diagnóstico clínico. Os dados relacionados à cirurgia foram tempo operatório, incisão da pele, registro de complicações intraoperatórias, necessidade de conversão para laparotomia, necessidade de transferência para unidade de terapia intensiva, necessidade de transfusão sanguínea, lesão inadivertida de outros órgãos, tempo de internação e óbito. Resultados: Todos os casos foram concluídos sem intercorrências com a plataforma da Vinci Single-Site®. Quatro pacientes apresentavam adenomiose como indicação cirúrgica, duas apresentavam mioma uterino, uma câncer de endométrio, um pólipo endometrial e uma hidrorreia. A média de idade das pacientes foi 44 anos (variando de 40 a 54 anos) e o índice de massa corporal variou entre 23,4 a 33,2kg/m2 (média de 26,4). Nenhum caso teve qualquer tipo de complicação, como lesão intestinal ou vesical, sangramento ou necessidade de reabordagem cirúrgica. Todos os nove procedimentos foram concluídos com o portal único robótico, e nenhuma paciente necessitou de transfusão sanguínea. Conclusão: Apesar deste trabalho apresentar apenas uma série inicial de pacientes operadas por portal único robótico, ele demonstra a factibilidade do método e indica a possibilidade futura de adotar esta técnica em histerectomias eletivas e em outros procedimentos ginecológicos, assim como descrito em grandes centros de referência em cirurgia avançada no mundo. Especificamente na prática ginecológica, a evidência existente sobre o uso de portal único robô-assistido parece ser promissora e, ainda que nem todos os casos tenham indicação, é necessário que exista esta opção no arsenal cirúrgico. No entanto, estudos clínicos aleatorizados e controlados são necessários, a fim de se estabelecer a superioridade da cirurgia robótica por portal único diante da cirurgia laparoscópica com incisão única e da cirurgia laparoscópica convencional.

Uterine leiomyoma is the most frequently occurring solid pelvic tumor in women during the reproductive period. Magnetic resonance-guided high-intensity focused ultrasound is a promising technique for decreasing menorrhagia and dysmenorrhea in symptomatic women. The aim of this study is to review the role of Magnetic resonance-guided high-intensity focused ultrasound in the treatment of uterine fibroids in symptomatic patients. We performed a review of the MEDLINE and Cochrane databases up to April 2016. The analysis and data collection were performed using the following keywords: Leiomyoma, High-Intensity Focused Ultrasound Ablation, Ultrasonography, Magnetic Resonance Imaging, Menorrhagia. Two reviewers independently performed a quality assessment; when there was a disagreement, a third reviewer was consulted. Nineteen studies of Magnetic resonance-guided high-intensity focused ultrasound-treated fibroid patients were selected. The data indicated that tumor size was reduced and that symptoms were improved after treatment. There were few adverse effects, and they were not severe. Some studies have reported that in some cases, additional sessions of Magnetic resonance-guided high-intensity focused ultrasound or other interventions, such as myomectomy, uterine artery embolization or even hysterectomy, were necessary. This review suggests that Magnetic resonance-guided high-intensity focused ultrasound is a safe and effective technique. However, additional evidence from future studies will be required before the technique can be recommended as an alternative treatment for fibroids.

Abstract Leiomyomas are smooth muscle tumors and may occur in places where these fibers are present, while the anorectal location is rare. They are commonly incidental imaging findings and in most cases, patients are asymptomatic. The therapeutic recommendation is tumor resection and postoperative follow-up. Case report: a 38-year-old Black woman had, one year ago, a swelling in perianal right region, which showed slow and progressive growth. She denied bowel habit alterations, local pain, hematochezia, or tenesmus. Proctologic examination showed a fibroelastic, regular, mobile, painless nodule measuring 10 cm at its largest diameter in the right perianal region, next to the anal verge. The soft tissue ultrasound image identified a solid, hypoechoic, and discreetly vascularized nodule in the perianal, superficial right gluteal region that did not reach the adjacent muscles. A complete resection of perineal tumor was carried out in the ventral position. Histological and immunohistochemical analyses disclosed a leiomyoma with a positive finding for actin smooth muscle and negative for desmin. She is currently asymptomatic and undergoing outpatient follow-up.

Resumo Os leiomiomas são tumores da musculatura lisa podendo ocorrer nos locais onde essas fibras estão presentes, sendo rara a localização anorretal. Na maioria dos casos os pacientes são assintomáticos, sendo comumente achados de exame de imagem. A recomendação terapêutica é a ressecção tumoral e o seguimento pós-operatório. Relato do caso: mulher, 38 anos, negra. Há um ano, apresentou abaulamento em região perianal direita, de crescimento lento e progressivo. Negava alteração do hábito intestinal, dor local, hematoquezia, puxo ou tenesmo. Ao exame proctológico, apresentava nodulação fibroelástica, regular, móvel, indolor, com 10 cm de diâmetro em região perianal à direita, próxima à borda anal. Realizou ultrassonografia de partes moles que identificou imagem nodular, sólida, hipoecogênica e discreta vascularização em parte superficial perianal e glútea direita, não envolvendo musculatura adjacente. Foi submetida à ressecção completa do tumor via perineal, em posição ventral. O laudo histológico e imuno-histoquímico revelou leiomioma, com achado positivo para actina de músculo liso e negativo para desmina. Atualmente está assintomática, em seguimento ambulatorial.
