RESUMO

Resumen Antecedentes: La cirugía de aumento mamario con lipoinjerto se ha incrementado debido a que evita usar prótesis. Es utilizado para aumentos moderados con fines estéticos, no retarda el diagnóstico de cáncer ni aumenta el riesgo de sufrirlo. Objetivo: Revisar nuestra experiencia en aumento mamario estético con lipoinjerto, en una sesión y con seguimiento superior a un año. Materiales y Método: Se diseñó una cohorte prospectiva de mujeres. Se excluyeron aquellas con alteraciones congénitas, mesenquimopatías y fumadoras. La lipoinyección se efectuó con principios de Coleman. Para la medición del volumen mamario preoperatorio se utilizó la aplicación Breast-V. Volumen de aumento, tasa de retención y tasa de aumento fueron calculados. Resultados: 73 pacientes fueron lipoinjertadas, 35 superaron seguimiento a un año. Volumen mamario inicial fue 219,5 ± 44,1 cc. Volumen de aumento fue 99,9 ± 29,8 cc, tasa de retención grasa injertada 41,4%, tasa de aumento del volumen mamario 48,1%. 41 pacientes presentaron imágenes posoperatorias: quistes 15 pacientes (36,6%); necrosis grasa 2 pacientes (4,9%); macrocalcificaciones 8 pacientes (19,5%); microcalcificaciones 1 paciente (2,5%), cuya biopsia fue negativa para malignidad. Discusión: El lipoinjerto mamario es un procedimiento seguro, con resultados adecuados cuando se realiza en una sesión y por el mismo cirujano, siguiendo principios de Coleman. El aumento porcentual es el índice más significativo para evaluar su éxito. Conclusiones: Lipoinyección mamaria en una sesión es una técnica segura que logra aumento moderado del volumen mamario. Es útil para aumentos moderados o corrección de asimetrías leves. No hay evidencia de que interfiera con el diagnóstico precoz del cáncer de mama.


Background: Lipograft breast augmentation has increased due to avoidance of prosthetics. It is used for moderate increases for aesthetic purposes, it does not delay the diagnosis of cancer or increase the risk of suffering it. Aim: To review our experience in cosmetic breast augmentation with lipograft, in one session and with a follow-up of more than one year. Materials and Method: A prospective cohort of women was designed. Those with congenital alterations, mesenchymopathies and smokers were excluded. Lipoinjection was carried out with Coleman's principies. The Breast-V application was used to measure preoperative breast volume. Volume of increase, retention rate and rate of increase were calculated. Results: 73 patients were lipografted, 35 had a one-year follow-up. Initial breast volume was 219.5 ± 44.1 cc. Volume increase was 99.9 ± 29.8 cc, grafted fat retention rate 41.4%, breast volume increase rate 48.1%. 41 patients presented postoperative images: cysts 15 patients (36.6%); fat necrosis 2 patients (4.9%); macrocalcifiations 8 patients (19.5%); microcalcifiations 1 patient (2.5%), whose biopsy was negative for malignancy. Discussion: The mammary lipograft is a safe procedure, with adequate results when performed in one session and by the same surgeon, following Coleman principles. The percentage increase is the most significant index to evalúate your success. Conclusions: Breast lipoinjection in one session is a safe technique that achieves a moderate increase in breast volume. It is useful for moderate magnification or correction of slight asymmetries. There is no evidence that it interferes with the early diagnosis of breast cancer.

RESUMO

Resumen Objetivo: Analizar la participación de los residentes de cirugía plástica de Chile en la publicación científica de los últimos 20 años y evaluar su experiencia durante la residencia. Materiales y Método: Revisión de la literatura desde 1998-2018 bajo los términos: Cirugía Plástica, Plastic Surgery y Chile. Se incluyeron aquellos con al menos un autor cirujano plástico con filiación en Chile. Se registró la participación reportada de residentes y analizaron sus autores según su período de residencia y fecha de publicación, agregándolos como residentes no reportados. Se analizó tema, año de publicación y revista. Se aplicó una encuesta a residentes de cirugía plástica y postbecados recientes para conocer la percepción sobre su participación en actividades científicas. Se comparó la participación entre residentes con y sin año de investigación mediante el test exacto de Fisher. Resultados: Predominó la temática reconstructiva (48,2%), en adultos (68,6%) y en centros universitarios (48,7%). La participación reportada de residentes fue de 8,4%, subiendo a 38,2% al ampliarla a los no explicitados como residentes. Los encuestados expusieron la falta de tiempo como principal impedimento a la publicación y participación en congresos. Discusión: La participación en actividades científicas resulta beneficiosa para residentes, sus tutores y la reputación académica de sus centros. La mayoría de los residentes cree que su participación podría haber sido mayor en caso de que se hubiesen dado más facilidades. Conclusiones: La participación de residentes de cirugía plástica se encuentra subreportada. Programas de investigación, tiempos protegidos y mayor tutorización podrían aumentar esta cifra.


Aim: Evalúate the participation of Chilean plastic surgery residents in scientific publication in the last 20 years and assess their experience during residency. Materials and Method: Literature review from 1998-2018 under the terms: Cirugia Plastica AND Plastic Surgery AND Chile. Publications with at least one plastic surgeon author with filiation reported in Chile were considered. Those with reported participation of residents were registered and their authors were also analyzed according to their period of residence and date of publication, adding them as unreported residents. Subjects, year of publication and journals were analyzed. A survey was applied to plastic surgery residents and recent plastic surgery graduates to evaluate the perception of their participation in scientific activities. Residents participation with and without a previous research fellow was compared using Fisher's exact test. Results: Reconstructive themed studies (48.2%), in adults (68.6%) and in university centers (48.7%) prevailed among the included articles. The reported participation of residents was 8.4%, which rised to 38.2% when it was extended to those not explicitly reported as residents among the authors. Residents exposed the lack of time as the main barrier to publication and congress participations. Discussion: Participation in scientific activities is beneficial for residents, their mentors and the academic reputation of their centers. The majority of residents believe that their participation could have been greater if more facilities had been given. Conclusions: Participation of plastic surgery residents in scientific publications is under reported. The implementation of research programs, protected times and active mentoring could increase this number.

RESUMO

Anatomic variations of the hepatic artery, which occur in 30 to 50% of patients, are a very important factor to be considered for Whipple procedure. The most common variations are those coming from the superior mesenteric artery, left gastric artery and the aorta. We report a 58-year-old woman with a story of one month of epigastric pain, jaundice and progressive itching. Magnetic resonance imaging showed a mass in the head of the pancreas. During pancreatoduodenectomy a left hepatic artery (LHA) emerging from the gastroduodenal artery and an accessory LHA emerging from the left gastric artery, were observed. The rest of the surgery was performed with no incidents. The patient had an uneventful postoperative evolution.
