Poliquistosis renal autosómica dominante: ¿quiénes se benefician del tratamiento con tolvaptán?. Estado del arte / Autosomal dominant polycystic kidney disease. Who can benefit from tolvaptan therapy? State of the art / Doença renal policística autossômica dominante: quem se beneficia do tratamento com tolvaptano? Estado da arte

Resumen: La poliquistosis renal autosómica dominante es la enfermedad renal hereditaria más frecuente. Se caracteriza por la progresiva aparición de quistes renales que suelen conducir a la enfermedad renal crónica extrema en la edad adulta. La aprobación del uso de tolvaptán (antagonista del receptor V2 de la vasopresina) ha marcado un cambio significativo en el tratamiento de esta enfermedad. En los últimos años apareció evidencia que demuestra el beneficio en iniciar tratamiento con tolvaptán en pacientes que presentan una enfermedad con rápida evolución. Se realiza una revisión descriptiva de los principales estudios clínicos publicados en el periodo 2012-2022 y se sugiere un esquema de utilidad para seleccionar aquellos pacientes que pueden beneficiarse del inicio de tratamiento.

Abstract: Autosomal dominant polycystic kidney disease is the most common hereditary kidney disease. It is characterized by the progressive appearance of renal cysts that usually lead to extreme chronic kidney disease in adulthood. The approval of the use of tolvaptán (V2 vasopressin receptor antagonist) has meant a significant change in the treatment of this disease. In recent years, evidence has proved the benefits of initiating treatment with tolvaptán in patients with a rapidly evolving disease. A descriptive review of the main clinical studies published in 2012-2022 period is carried out and a useful scheme is suggested to select those patients who can benefit from the start of treatment.

Subfenótipos baseados em dados clínicos de beira-leito de pacientes críticos com COVID-19: um estudo de coorte / Bedside clinical data subphenotypes of critically ill COVID-19 patients: a cohort study

RESUMO Objetivo: Identificar apresentações mais graves de COVID-19. Métodos: Pacientes consecutivamente admitidos à unidade de terapia intensiva foram submetidos à análise de clusters por meio de método de explorações sequenciais Resultados: Analisamos os dados de 147 pacientes, com média de idade de 56 ± 16 anos e Simplified Acute Physiological Score 3 de 72 ± 18, dos quais 103 (70%) demandaram ventilação mecânica e 46 (31%) morreram na unidade de terapia intensiva. A partir do algoritmo de análise de clusters, identificaram-se dois grupos bem definidos, com base na frequência cardíaca máxima [Grupo A: 104 (IC95% 99 - 109) batimentos por minuto versus Grupo B: 159 (IC95% 155 - 163) batimentos por minuto], frequência respiratória máxima [Grupo A: 33 (IC95% 31 - 35) respirações por minuto versus Grupo B: 50 (IC95% 47 - 53) respirações por minuto] e na temperatura corpórea máxima [Grupo A: 37,4 (IC95% 37,1 - 37,7)ºC versus Grupo B: 39,3 (IC95% 39,1 - 39,5)ºC] durante o tempo de permanência na unidade de terapia intensiva, assim como a proporção entre a pressão parcial de oxigênio no sangue e a fração inspirada de oxigênio quando da admissão à unidade de terapia intensiva [Grupo A: 116 (IC95% 99 - 133) mmHg versus Grupo B: 78 (IC95% 63 - 93) mmHg]. Os subfenótipos foram distintos em termos de perfis inflamatórios, disfunções orgânicas, terapias de suporte, tempo de permanência na unidade de terapia intensiva e mortalidade na unidade de terapia intensiva (com proporção de 4,2 entre os grupos). Conclusão: Nossos achados, baseados em dados clínicos universalmente disponíveis, revelaram dois subfenótipos distintos, com diferentes evoluções de doença. Estes resultados podem ajudar os profissionais de saúde na alocação de recursos e seleção de pacientes para teste de novas terapias.

Abstract Objective: To identify more severe COVID-19 presentations. Methods: Consecutive intensive care unit-admitted patients were subjected to a stepwise clustering method. Results: Data from 147 patients who were on average 56 ± 16 years old with a Simplified Acute Physiological Score 3 of 72 ± 18, of which 103 (70%) needed mechanical ventilation and 46 (31%) died in the intensive care unit, were analyzed. From the clustering algorithm, two well-defined groups were found based on maximal heart rate [Cluster A: 104 (95%CI 99 - 109) beats per minute versus Cluster B: 159 (95%CI 155 - 163) beats per minute], maximal respiratory rate [Cluster A: 33 (95%CI 31 - 35) breaths per minute versus Cluster B: 50 (95%CI 47 - 53) breaths per minute], and maximal body temperature [Cluster A: 37.4 (95%CI 37.1 - 37.7)°C versus Cluster B: 39.3 (95%CI 39.1 - 39.5)°C] during the intensive care unit stay, as well as the oxygen partial pressure in the blood over the oxygen inspiratory fraction at intensive care unit admission [Cluster A: 116 (95%CI 99 - 133) mmHg versus Cluster B: 78 (95%CI 63 - 93) mmHg]. Subphenotypes were distinct in inflammation profiles, organ dysfunction, organ support, intensive care unit length of stay, and intensive care unit mortality (with a ratio of 4.2 between the groups). Conclusion: Our findings, based on common clinical data, revealed two distinct subphenotypes with different disease courses. These results could help health professionals allocate resources and select patients for testing novel therapies.

Tratamiento quirúrgico de la endocarditis infecciosa activa / Active infective endocarditis: surgical treatment

Resumen: La endocarditis infecciosa, la infección cardiovascular en general, es una enfermedad médico-quirúrgica compleja que requiere un tratamiento multidisciplinario precoz, específico y agresivo. A pesar de los avances médicos, ésta sigue siendo una enfermedad con una morbi-mortalidad elevada, por lo que el tratamiento antibiótico se complementa en un 40-50% de los pacientes mediante intervención quirúrgica. Por lo tanto, es necesario conocer las opciones que pueden llegar a ser utilizadas para extirpar el tejido infectado. El objetivo de este trabajo es discutir aspectos de interés en la cirugía de la endocarditis infecciosa.

Abstract: Infective endocarditis (IE) is a complex disease that requires a multidisciplinary approach and early and aggressive treatment. Despite médical and surgical advances, this disease still has high morbidity and mortality. The antibiotic treatment is complemented in 40-50% of the cases with surgical intervention. Thus, it is useful to be aware of the possibilities that might be contemplated in order to excise the infected tissues. The aim of this work is to discuss current surgical aspects of interest in the surgery IE.

Consensus on diagnosis and management of non-metastatic castration resistant prostate cancer in Brazil: focus on patient, selection, treatment efficacy, side effects and physician's perception according to patient comorbidities

ABSTRACT Background: Non-metastatic castration resistant prostate cancer (M0 CRPC) has seen important developments in drugs and diagnostic tools in the last two years. New hormonal agents have demonstrated improvement in metastasis free survival in M0 CRPC patients and have been approved by regulatory agencies in Brazil. Additionally, newer and more sensitive imaging tools are able to detect metastasis earlier than before, which will impact the percentage of patients staged as M0 CRPC. Based on the available international guidelines, a group of Brazilian urology and medical oncology experts developed and completed a survey on the diagnosis and treatment of M0 CRPC in Brazil. These results are reviewed and summarized and associated recommendations are provided. Objective: To present survey results on management of M0 CRPC in Brazil. Design, setting, and participants: A panel of six Brazilian prostate cancer experts determined 64 questions concerning the main areas of interest: 1) staging tools, 2) treatments, 3) side effects of systemic treatment/s, and 4) osteoclast-targeted therapy. A larger panel of 28 Brazilian prostate cancer experts answered these questions in order to create country-specific recommendations discussed in this manuscript. Outcome measurements and statistical analysis: The panel voted publicly but anonymously on the predefined questions. These answers are the panelists' opinions, not a literature review or meta-analysis. Therapies not yet approved in Brazil were excluded from answer options. Each question had five to seven relevant answers including two non-answers. Results were tabulated in real time. Conclusions: The results and recommendations presented can be used by Brazilian physicians to support the management of M0 CRPC patients. Individual clinical decision making should be supported by available data, however, for Brazil, guidelines for diagnosis and management of M0 CRPC patients have not been developed. This document will serve as a point of reference when confronting this disease stage.

SLAP en pacientes no deportistas. Resultados funcionales con un mínimo de dos años de seguimiento y factores de riesgo para retorno a las actividades / Non-athlete patients treated for SLAP lesion. Results with a minimum of two years of follow-up and risk factors for return-to-activity

Introducción: el objetivo de este trabajo es reportar y analizar los resultados con un mínimo de dos años de seguimiento en pacientes no deportistas tratados por lesión SLAP. Secundariamente, analizar las variables: tipo se lesión, score ASES y antecedente de trauma y su relación con el retorno a las actividades habituales.Materiales y métodos: se evaluaron veintinueve pacientes tratados por lesiones de SLAP con seguimiento mínimo de veinticuatro meses, operados por dolor, sin inestabilidad evidente, 82.76% fueron hombres. La edad promedio fue 36.82 años. Se evaluó la función en el preoperatorio y en el último seguimiento con el score de ASES, movilidad y retorno a las actividades previas. Se analizaron los resultados y los factores de riesgo para impedir este retorno.Resultados: catorce pacientes (48.28%) asociaron un trauma. Fueron ocho (27.59%) SLAP tipo I, diecisiete (58.62%) tipo II y cuatro pacientes (13.79) tipo V. Retornaron a su actividad previa veintiuno de ellos (72.41%). Se repararon las lesiones SLAP tipo II y V y se realizó desbridamiento en aquellas tipo I. Se obtuvo una diferencia estadísticamente significativa entre los valores pre y postoperatorios con mejoría de la movilidad en flexión anterior de 163.96 a 173.4°, rotación interna de 58.27 a 71.72°, rotación externa de 61.55 a 76.89° (p <0.05) y en el score ASES preoperatorio 56.51 a 90.24 (p <0.05). No así en el subgrupo que no retornó a su actividad previa. La complejidad de la lesión SLAP influyó negativamente en dicho retorno.Conclusión: los resultados con la reparación o desbridamiento artroscópico son funcionales, con alta tasa de retorno a la actividad previa. Los peores resultados se relacionaron a las lesiones SLAP de mayor severidad

Introduction: The objective of this work will be to report and analyze the results with a minimum of two years of follow-up in non-athlete patients treated for SLAP lesion and to analyze the following variables: type of SLAP, ASES score and history of trauma with the return to normal activities. Materials and methods: twenty-nine patients treated for SLAP lesions with a minimum follow-up of twenty-four months, operated due to pain, without evident instability were evaluated, 82.76% were male. The average age was 36.82. The function was evaluated in the preoperative period, and in the last follow-up with the ASES score and mobility. The results and risk factors for not returning to their previous activity were analyzed as well. Results: fourteen patients (48.28%) had associated trauma. There were eight (27.59%) SLAPS type I, seventeen (58.62) type II and four (13.79) type V. Twenty-one (72.4%) patients returned to their previous activity. SLAP type II and V were repaired and type I were debrided. A statistically significant difference was obtained between the preoperative and final evaluation of anterior flexion (163.96 to 173.4°), internal rotation (58.27 to 71.72°), external rotation (61.55 to 76.89°) ( p <0.05) and ASES score (56.51 to 90.24) (p <0.05). Instead, this does not occur in the subgroup that did not return to its previous activities. The complexity of the SLAP lesion influenced this return. Conclusions: the results of SLAP lesion arthroscopic reconstruction are functional with a high rate of return to the patient previous activity. The worst results are related to greater slap severity

Abstract Objective To evaluate the functional outcomes of patients diagnosed with femoroacetabular impingement (FAI) older than 60 years, compared with those of patients of age 40 years or younger. Methods This was a retrospective review of patients with FAI who underwent hip arthroscopy between 2010 and 2015. The patients were adults aged over 60 years with Tönnis ≤ 1 matched in a 1:1 ratio with adults aged 40 years or younger, according to the type of deformity (cam, pincer, or mixed), sex, and the date when the surgery was performed. Results Thirty-four patients were included in each group. The mean age was 30.6 ± 6.9 years and 65.6 ± 4.6 years in the control and case groups, respectively. There were no significant differences between the groups at 1-year follow-up (p > 0.05). In the group with older patients (case group), we observed a change in the total Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score from 46.3 to 22.0 in the 1st postoperative year, while the control cases improved in the WOMAC score from 38.1 to 7.2 in relation to the preoperative stage. Conclusion In the group of patients ≤ 40 years old, a considerable change was observed in the WOMAC score without a statistical significance compared with the > 60 years group. This observation suggests that hip arthroscopy is beneficial when there is an appropriate selection of patients with FAI, regardless the age of the patient.

Resumo Objetivo Avaliar os resultados funcionais de pacientes diagnosticados com impacto femoroacetabular (IFA) e com mais de 60 anos de idade em comparação aos resultados de pacientes com até 40 anos de idade. Métodos Esta é uma revisão retrospectiva de pacientes com IFA submetidos à artroscopia do quadril entre 2010 e 2015. Os pacientes eram adultos com mais de 60 anos de idade e Tönnis ≤ 1, alocados na proporção de 1:1 com adultos de até 40 anos de idade, de acordo com o tipo de deformidade (came, pincer, ou misto), sexo e data de realização da cirurgia. Resultados Trinta e quatro pacientes foram incluídos em cada grupo. A idade média foi de 30,6 ± 6,9 anos e 65,6 ± 4,6 anos nos grupos controle e de casos, respectivamente. Não houve diferenças significativas entre os grupos no acompanhamento de 1 ano (p > 0.05). No primeiro ano após a cirurgia, a pontuação Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) passou de 46,3 para 22,0 no grupo de pacientes mais velhos (casos) e de 38,1 para 7,2 no grupo controle em comparação ao estágio pré-operatório. Conclusão O grupo de pacientes com até 40 anos de idade apresentou uma mudança considerável na pontuação WOMAC, mas sem significado estatístico em comparação ao grupo de pacientes acima de 60 anos. Essa observação sugere que a artroscopia do quadril é benéfica quando a seleção de pacientes com IFA é apropriada, independentemente da idade dos indivíduos.

Identificación y análisis de los ensayos clínicos intervencionales planificados y registrados sobre COVID-19 / Identification and analysis of ongoing registered clinical intervention trials on COVID-19

Introducción La infección por SARS CoV-2 fue declarada pandemia el 11 de marzo de 2020. Desde entonces, se han propuesto e iniciado numerosos estudios, cuyo propósito incluye prevención, diagnóstico, manejo y tratamiento de esta nueva enfermedad. Objetivo Identificar y categorizar los estudios intervencionales hasta mayo de 20202 relacionados con la infección por SARS-CoV-2, de acuerdo con población y ubicación geográfica (con énfasis en Latinoamérica) y comprobar si existe correlación según el propósito, fase y estado de reclutamiento de los mismos. Metodología Se seleccionaron 1672 de los 1705 estudios disponibles en la plataforma de ensayos clínicos de la Organización Mundial de la Salud (OMS) relacionados con COVID-19. Se utilizaron las herramientas Jupyter y Python para el procesamiento y depuración de datos. Resultados Se encontraron 1672 estudios de tipo intervencional relacionados con la infección por SARS-CoV-2. China, Estados Unidos, Irán, Francia y España son los países que participan en mayor cantidad de estudios, mientras que solamente 4,1% proviene de América Latina (mayoritaria-mente brasileños). Las investigaciones que se centran únicamente en adultos mayores son 28, y solamente 10 estudios se basan exclusivamente en población menor de 19 años. Conclusión El interés mundial por esta nueva enfermedad se ve reflejado en la cantidad creciente de estudios intervencionales que se han realizado hasta la fecha. Sin embargo, los estudios analizados no abarcan proporcionalmente los grupos etarios más vulnerables, y no cuentan con una participa-ción equitativa de los países del orbe. En el caso de América Latina se agudiza esta problemática debido a las limitaciones sociales, económicas y políticas de la región. Debido a que es una enfermedad emergente, aún no existe suficiente información para poder establecer correlaciones contundentes entre las variables estudiadas. La estandarización definitiva de protocolos resulta prematura, ya que la mayoría de los estudios se encuentran en curso.

Introduction The World Health Organization declared the disease caused by the novel coronavirus (SARS-CoV-2), a pandemic on March 11, 2020. Several studies have been proposed and started since then, mainly covering prevention, diagnosis, management, and treatment. Objective To identify and categorize all intervention studies up to the end of May related to SARS-CoV-2 infection, according to population and geo-graphical location (emphasis in Latin America) and to verify if there is any correlation according to purpose, phase, and recruitment status. Methods One thousand six hundred seventy-two trials were selected from 1705 until May 24 on the World Health Organization clinical trials platform related to COVID-19. Jupyter and Python tools were used for data processing and cleaning. Results One thousand six hundred seventy-two intervention studies related to SARS-CoV-2 infection were found. China, The United States, Iran, France, and Spain are the countries participating in the largest number of studies, while only 4,1% are from Latin America (mostly Brazilian). 28 studies are focusing only on older adults, and ten studies are based exclusively on populations under 19 years of age. Conclusion The worldwide interest in this new disease is reflected in the increasing number of intervention studies that are being carried out to date. How-ever, the studies analyzed do not cover the most vulnerable age groups proportionally and do not have equitable participation of all the coun-tries. In Latin America, this problem is exacerbated by the region's social, economic, and political limitations. Because it is an emerging disease, there is still not enough information to establish strong correlations between the analyzed variables, and the standardization of protocols is not yet definite because most of the studies are in progress.

Recomendaciones en el manejo de pacientes de medicina reproductiva en tiempos de SARS-CoV-2: Un resumen de la literatura / Management recommendation of reproductive medicine patients in SARS-CoV-2 time: A literature summarize

La pandemia de SARS-CoV-2 es una emergencia sanitaria sin precedentes, que ha implicado un reordenamiento en la priorización de procedimientos médicos electivos, frente a un potencial colapso del sistema de salud a nivel mundial y riesgo de contagio del personal y pacientes. Al igual que en el resto del mundo, en Chile la mayoría de los centros de medicina reproductiva han debido suspender sus diferentes terapias de reproducción asistida (TRA). Sin embargo, a raiz de la disminución del número de contagios y mayor evidencia científica disponible, la Sociedad Europea de Reproducción Humana y Embriología (ESHRE) ha recomendado reiniciar los ciclos de medicina reproductiva de forma gradual, a través de sistemas de triage, priorizando pacientes por medio de la generación de distintos escenarios. Considerando esta recomendación, se realizó una revisión sobre la evidencia existente respecto a SARS-CoV-2 / COVID-19 en medicina reproductiva recopilando diferentes directrices de las principales sociedades internacionales, con el objetivo de generar una recomendación ajustada a la realidad nacional.

SARS-CoV-2 pandemic is an unprecedented health emergency, which involves a reorganization of elective procedures, facing a potential global health system collapse. In Chile, as in the rest of the world. most reproductive medicine centers have suspended their different assisted reproduction therapies (ART). However, due to the decrease in the number of infections and due to a greater collection of scientific evidence, the European Society for Human Reproduction and Embryology (ESHRE) have recommended restarting cycles gradually through triage systems, prioritizing patients through the generation of different scenarios. With this in mind, we carried out a review of the existing evidence so far regarding SARS-CoV-2 and reproductive medicine, and we tried to compile the different guidelines of the main international societies, to generate a recommendation adjusted to our local scenario.

Cirugía bariátrica en adolescentes con obesidad severa: recomendaciones de la Rama de Nutrición, Sociedad Chilena de Pediatría / Bariatric surgery in adolescents with severe obesity: recommendations of the Nutrition Branch, Chilean Pediatric Society

Resumen: En los últimos años, la obesidad severa en adolescentes ha aumentado a nivel mundial y Chile no es la excepción a este fenómeno. Es conocido que esta condición aumenta exponencialmente los riesgos para la salud y se asocia a mortalidad prematura. Desde el año 2008, diversas guías de tratamiento de obesidad pediátrica han incluido a la cirugía bariátrica como una estrategia de tratamiento para adolescentes obesos severos seleccionados. Estos procedimientos han mostrado ser seguros y eficaces en adultos. Un cuerpo emergente de evidencia demuestra que, en centros especializados, en el corto y mediano plazo se obtendrían resultados similares en adolescentes. Sin embargo, en este grupo de pacientes, la cirugía bariátrica tiene implícitos otros riesgos inherentes a la etapa de desarrollo en que se encuentran, y los resultados y complicaciones especialmente de largo plazo en gran medida son aún desconocidos. Por lo anterior y para el logro de los resultados esperados, es muy importante que la selección de pacientes, la cirugía y el seguimiento, sean realizados por equipos multidisciplinarios calificados, en centros hospitalarios que cuenten con la infraestructura adecuada, siendo imprescin dible la adherencia de por vida al seguimiento médico y nutricional. El objetivo de este documento es presentar la postura de la Rama de Nutrición de la Sociedad Chilena de Pediatría (SOCHIPE) frente a las diversas aristas a considerar para la adecuada indicación de estos procedimientos en adolescentes obesos severos.

Abstract: In recent years, severe obesity in adolescents has been rising worldwide, and Chile is no exception to this phenomenon. This condition exponentially increases health risks and it is associated with prema ture mortality. Since 2008, several guidelines on pediatric obesity treatment have included bariatric surgery as a treatment strategy for certain severely obese adolescents. These procedures have proven to be safe and efficient in adults. Recent evidence shows that, when done in specialized centers, the re sults would be similar in adolescents in the short and medium term. Nonetheless, in this group of pa tients, bariatric surgery has risks related to their stage of development, and data on long-term results and complications are still lacking. Therefore, to achieve the expected results, the patient selection, surgery, and follow-up must be carried out by qualified multidisciplinary teams, in hospitals centers that have the appropriate infrastructure, It is essential for the patients a life-long adherence to medi cal and nutritional monitoring. The objective of this document is to present the position statement of the Nutrition Branch of the Chilean Society of Pediatrics on the different issues to be considered for the adequate indication of these procedures in severely obese adolescents.

Histeroscopía quirúrgica: experiencia, resultados y complicaciones según clasificación Clavien-Dindo / Surgical hysteroscopy: experience, results and complications according to Clavien-Dindo classification

OBJETIVO: Describir y analizar la experiencia clínica, resultados y complicaciones según Clavien-Dindo de las histeroscopías quirúrgicas realizadas en pabellón. MÉTODOS: Estudio descriptivo retrospectivo de las histeroscopías quirúrgicas realizadas entre el 1 de enero de 2012 y 1 de enero de 2018 en el Hospital Clínico de la Universidad de Chile. RESULTADOS: Hubo 613 histeroscopías quirúrgicas en el período analizado, de las cuales 593 cumplieron con los requisitos para incluirse en este estudio. Las indicaciones para realizar el procedimiento fueron: pólipo endometrial (56,3%), miomas uterinos (22,1%), sangrado uterino anormal (4,3%) y otras (17,7%). Hubo un 89,2% de concordancia entre el diagnóstico intraoperatorio y el estudio histopatológico. Se pesquisaron 11 hiperplasias endometriales sin atipías, 3 con atipías y 10 neoplasias malignas. Cabe destacar que, del total de pólipos resecados, hubo 8 casos (2,5%) con potencial malignidad (atipías o neoplasia maligna). Según la clasificación Clavien Dindo, hubo 22 complicaciones intraoperatorias (3,7%) grado I o II, cuyo diagnóstico fue realizado en el acto quirúrgico. No hubo complicaciones grado III o más (severas, con reintervención). CONCLUSIÓN: La tasa de éxito, correlación histeroscópica - anatomopatológica final y complicaciones fue similar a lo publicado en la literatura disponible. El diagnóstico intraoperatorio de la lesión y su reparación en el mismo acto quirúrgico, disminuye el riesgo de morbimortalidad de las pacientes, haciéndolo similar al de una paciente sin complicación. Utilizar la clasificación Clavien Dindo para evaluar las complicaciones nos permitirá en adelante, objetivar, mejorar aspectos del procedimiento quirúrgico y plantear estrategias de prevención y manejo de dichos eventos adversos.

OBJECTIVE: To describe and analyze the clinical experience, results and complications according to Clavien-Dindo of surgical hysteroscopies performed in the ward. METHODS: Retrospective descriptive study of surgical hysteroscopies performed between January 1, 2012 and January 1, 2018 at the Hospital Clinico of the University of Chile. RESULTS: There were 613 surgical hysteroscopies in the analyzed period of which 593 fulfilled the requirements to be included in this study. The indications to perform the procedure were: endometrial polyp (56.3%), uterine fibroids (22.1%), abnormal uterine bleeding (4.3%) and others (17.7%). There was an 89.2% agreement between the intraoperative diagnosis and the histopathological study. Eleven endometrial hyperplasias without atypia, 3 with atypia and 10 malignant neoplasms were investigated. It should be noted that, of the total of resected polyps, there were 8 cases (2.5%) with potential malignancy (atypia or malignant neoplasm). According to the Clavien Dindo classification, there were 22 intraoperative complications (3.7%) grade I or II, the diagnosis of which was made during surgery. There were no grade III or more complications (severe, with reoperation). CONCLUSION: The success rate, final hysteroscopic-pathological correlation and complications was similar to that published in the available literature. The intraoperative diagnosis of the lesion and its repair in the same surgical act, reduces the risk of morbidity and mortality of the patients, making it similar to that of a patient without complication. Using the Clavien Dindo classification to assess complications will henceforth allow us to objectify, improve aspects of the surgical procedure and propose strategies for the prevention and management of such adverse events.
