Ginecomastia: Consideraciones médicas y quirúrgicas en cirugía general / Gynecomastia: Medical and surgical considerations in general surgery

La ginecomastia, definida como el crecimiento del tejido glandular mamario en los hombres, aparece desde la etapa neonatal hasta la senil, puede ser unilateral o bilateral, y es de causa multifactorial, incluyendo aquellos pacientes asociados al uso de medicamentos, donde predomina un desbalance en la relación testosterona­estrógeno. Relativamente, la idiopática es la más frecuente. La mayoría involucionan espontáneamente, las neonatales por perdida del influjo transplacentario en las primeras semanas, y las puberales entre 12 a 24 meses. Se presenta como un aumento del tamaño mamario, asintomático o con hipersensibilidad por inflamación durante el crecimiento del tejido fibroglandular mamario, con una repercusión psicológica enorme, sobre todo en la etapa de la adolescencia. El estudio y manejo es interdisciplinario y se ofrece de acuerdo con las condiciones y la etiología. Aquellos pacientes púberes en quienes no involuciona reciben tratamientos médicos, o tratamientos quirúrgicos cuando falla la terapéutica o hay presión social, e incluso radioterapia en casos donde desarrollan ginecomastia con hipersensibilidad al tratamiento hormonal del cáncer de próstata

Gynecomastia, defined as the growth of breast glandular tissue in men, appears from the neonatal to senile stage, can be unilateral or bilateral, and is of multifactorial cause, including those patients associated with the use of medications, where an imbalance in the testosterone ­ estrogen ratio. Relatively, idiopathic is the most common. Most regress spontaneously, neonatals due to loss of transplacental influx in the first weeks, and pubertal ones between 12 to 24 months. It presents as an increase in breast size, asymptomatic or with hypersensitivity due to inflammation during the growth of the mammary fibroglandular tissue, with an enormous psychological repercussion, especially in adolescence. The study and management is interdisciplinary and offered according to conditions and etiology. Those pubertal patients in whom it does not regress receive medical treatments, or surgical treatments when therapy fails or there is social pressure, and even radiotherapy in cases where they develop gynecomastia with hypersensitivity to hormonal treatment of prostate cancer

Trends in breast cancer surgery in private patients under opportunistic screening / Tendências na cirurgia de câncer de mama em pacientes de um serviço privado sob rastreio oportunístico

Objective: This study aims to determine the evolution of staging and surgical treatment in patients with breast cancer in a private clinic over the last 40 years. Methods: Retrospective descriptive observational study, through statistical analysis of the medical records of 2105 patients treated at a private clinic in Curitiba, Paraná, between 1977 and 2017. Results: Data analyzed from 2,105 patients diagnosed with breast cancer revealed that, over time, radical surgeries predominated when compared to conservative ones. However, when analyzed proportionally over the years, it is possible to observe an inversion of the surgical modalities. It was demonstrated that from 1977 to 2017, there was a 273% increase in the number of conservative surgeries and a 45.5% decrease in mastectomies. In addition to this data, there was a decrease in the number of axillary emptying and, consequently, of positive sentinel lymph nodes. In addition, tumors diagnosed early (T1) have increased over the years. Conclusion: Patients had an early diagnosis of the disease, resulting in less invasive surgical treatments and, consequently, lower morbidity and mortality.

Objetivo: A pesquisa visa determinar a evolução do estadiamento e do tratamento cirúrgico em pacientes com câncer de mama em uma clínica privada, nos últimos 40 anos. Métodos: Estudo observacional descritivo retrospectivo, por meio da análise estatística dos prontuários de 2105 pacientes atendidas em clínica privada em Curitiba, Paraná, entre 1977 e 2017. Resultados: Dados analisados de 2.105 pacientes diagnosticadas com câncer de mama revelaram que, ao longo do tempo, as cirurgias radicais predominaram quando comparadas às cirurgias conservadoras. No entanto, quando analisadas proporcionalmente ao longo dos anos, é possível constatar uma inversão das modalidades cirúrgicas. Demonstrou-se que de 1977 a 2017, houve aumento de 273% do número das cirurgias conservadoras e queda de 45,5% das mastectomias. Associado a esse dado, notou-se diminuição do número de esvaziamento axilar e consequentemente de linfonodos sentinela positivos. Além disso, os tumores diagnosticados em fase inicial (T1) aumentaram ao longo dos anos. Conclusão: As pacientes tiveram um diagnóstico em estadiamento mais precoce da doença, proporcionando tratamentos cirúrgicos menos invasivos e, consequentemente, menor morbidade.

Reconstrução mamária com implantes e tela sintética / Breast reconstruction with implants and synthetic mesh

Introdução: As mastectomias com reconstruções mamárias imediatas podem proteger a paciente de um período de estresse psicossocial, imagem corporal negativa e insatisfação sexual. O advento e utilização de novos materiais como os implantes, expansores e matrizes dérmicas acelulares também contribuíram para o sucesso das reconstruções mamárias. Porém, o uso das matrizes dérmicas acelulares é restrito no Brasil pela legislação e seu alto custo. O objetivo do estudo foi relatar a experiência do autor na reconstrução mamária com implantes e tela sintética como uma alternativa às matrizes dérmicas acelulares. Método: Foi realizada uma análise retrospectiva de 12 pacientes consecutivas (20 mamas reconstruídas) que foram submetidas à reconstrução mamária imediata ou tardia pela técnica descrita com implantes e tela sintética, entre novembro de 2015 e dezembro de 2016. Resultados: Doze pacientes (20 mamas) foram operadas pela técnica apresentada no estudo. O tempo médio de follow-up foi de 14 meses. Nesta série, 15% apresentaram complicações menores como hematoma, deiscência de sutura e rippling. O número de complicações, apesar do número restrito de casos, é compatível com a literatura. O grau de satisfação global com a cirurgia foi, em média, de 75,2 pontos em uma escala de 0-100, sendo a nota mais alta atribuída à aparência das mamas (85 pontos). Conclusão: A reconstrução mamária com implantes e tela sintética se mostrou uma técnica com baixo índice de complicações, alto grau de satisfação das pacientes com o resultado estético e com menores custos em relação ao uso de matrizes dérmicas acelulares.

Introduction: Mastectomy with immediate breast reconstruction may prevent patients from experiencing a period of psychosocial stress, negative body image, and sexual dissatisfaction. The advent and implementation of novel materials such as implants, expanders, and acellular dermal matrices have also contributed to the success of breast reconstruction procedures. However, the use of acellular dermal matrices in Brazil is restricted by law and by their high cost. The objective of the present study was to report the author's experience in breast reconstruction with implants and synthetic mesh as an alternative to acellular dermal matrices. Method: This was a retrospective analysis of 12 consecutive patients (20 reconstructed breasts) who underwent immediate or delayed breast reconstruction using the described technique with implants and synthetic mesh between November 2015 and December 2016. Results: Twelve patients (20 breasts) were operated on using the technique described in this report. The mean time of follow-up was 14 months. In this series, 15% of patients had minor complications, including hematoma, suture dehiscence, and rippling. The rate of complications was similar to the rates reported in the literature, despite the limited number of cases. The average degree of overall satisfaction with the surgery was 75.2 points on a scale of 0-100, and the highest score was given to breast appearance (85 points). Conclusion: Breast reconstruction with implants and synthetic mesh was shown to be a technique with a low rate of complications, high degree of patient satisfaction with the cosmetic result, and decreased cost relative to acellular dermal matrices.

En este centro solo se ha diagnosticado este caso desde 1985

Introduction: primary angiosarcoma of the breast is a rare tumor of blood vessels, which account 8 per cent of breast sarcomas and 1 per cent of malignant breast lesions. It occurs between the third and fourth decades of life, with a mortality approaching 90 per cent two years later. The etiology is not well specified. It spreads mainly hematogenously to the lungs and bones and rarely by the lymphatic via. Surgery offers the best chance of treatment, while radio and chemotherapy are not associated with good response. The reported mean survival is about 20 months.Objective: to report the case of a patient with a diagnosis of angiosarcoma of the breast, and this case behavior and evolution.Methods: a literature review was carried out on the subject. Details of the diagnosis of angiosarcoma of the breast and its treatment in an 85 year-old patient treated at Guanabacoa Teaching Hospital is presented here.Results: a simple mastectomy without axillary clearance was performed on February 9, 2009. No adjuvant was used. This patient was followed up for two years until her death due to lung metastases.Conclusion: the histological diagnosis was angiosarcoma of the breast.
