Background: An informed consent is mandatory to obtain any clinical audiovisual material from patients. Although there are some documents created for this purpose, there are some barriers for their application, such as the context in which they were created, the language and download availability. Aim: To create a proposal for an informed consent form (ICF) for the capture and different uses for audiovisual material from patients. Material and Methods: A bibliographic search was carried out to obtain different ICFs in Spanish and English, which were subjected to a process of translation, counter-translation and fragmentation. Subsequently, a panel of experts was formed by members of the Chilean Society of Plastic Surgery with extensive experience in social networks. Delphi methodology was applied to reach a consensus about the definitive content of the ICF based on the previously selected fragments. Results: ICFs available for download were identified. The panel was made up of seven Plastic Surgeons and two Delphi rounds were carried out through electronic surveys. At the end of the process, an ICF proposal was obtained for therapeutic, academic or scientific purposes and another for dissemination or education in the mass media. Conclusions: The proposed ICFs were liberated for their use among health care professionals in Chile, who could use them, provided that they are approved by the local healthcare ethics committees.

Abstract Acute compartment syndrome (ACS) is the increase of pressure in a closed osteofascial space. This reduces capillary perfusion below the level necessary for tissue viability. Injury could be irreversible if proper treatment is not performed. Hand ACS secondary to cutaneous loxoscelism with edematous predominance is extremely infrequent. We present a clinical case of a 22-year-old patient who started a hand compartment syndrome secondary to cutaneous loxoscelism (CL), requiring emergency surgical treatment with dorsal and palmar fasciotomy.

Resumen El síndrome compartimental agudo (SCA) es el aumento de la presión en un espacio osteofascial cerrado. Esto reduce la presión capilar bajo el nivel necesario para la viabilidad de los tejidos del compartimento. El SCA de mano como complicación de un loxoscelismo cutáneo (LC) de predominio edematoso es muy poco frecuente. Presentamos el caso de una mujer de 22 años que presentó un SCA de la mano secundario a un LC y que requirió tratamiento quirúrgico de urgencia mediante una fasciotomía dorsal y palmar.

Abstract Background and objective Unlike oncological results there are no standard methods to evaluate aesthetic results. Many studies have evaluated cosmetic results and quality of life after breast cancer surgery with very inconsistent results perhaps due to the use of unconfirmed subjective evaluations, the small size of the population study, the retrospective design of the studies and differences in measures of quality of life. Our objective is to determine the quality of life status with Breast-Q® instrument (previously authorized by 2018 Mapi Research Trust© and also validated for its application in Spanish), in women with post-mastectomy breast reconstruction in 2013-2018. Methods Cohort study including patients diagnosed with breast cancer who underwent breast reconstruction. Quality of life was measured by the Breast-Q® instrument in its Spanish version. The quantitative variables are shown as averages and standard deviation. Qualitative data such as frequencies and percentages. The analysis of the before and after breast reconstruction with the Wilcoxon test. A value p<0.05 was taken as significant. The statistical package SPSS version 22 was used to analyze the data. Results Satisfaction regarding their nipples, their thorax, the referred information, and in general is above 75 points out of 100. Interestingly, psychological well-being is also above 75 on average. When comparing the before and after satisfaction with their breasts and sexual well-being, a statistically significant increase was found. Conclusions The evaluation using the Breast-Q® instrument among our study group showed that breast reconstruction improves the quality of life of patients undergoing this procedure.

Resumen Introducción y objetivo A diferencia de los resultados oncológicos, no existen métodos estándar para evaluar los resultados estéticos. Muchos estudios han evaluado resultados cosméticos y calidad de vida después de la cirugía de cáncer de mama; los resultados fueron muy inconsistentes, tal vez debido al uso de evaluaciones subjetivas no confirmadas, al pequeño tamaño poblacional del estudio, al diseño retrospectivo y las diferencias en las medidas de calidad de vida. El objetivo del presente estudio es determinar el estado de calidad de vida con el instrumento Breast-Q® (previamente autorizado por 2018 Mapi Research Trust© y validado también para su aplicación en español) en mujeres sometidas a reconstrucción mamaria postmastectomía entre 2013-2018. Material y método Estudio de cohorte que incluye pacientes con diagnóstico de cáncer de mama sometidas a reconstrucción mamaria. Medimos su calidad de vida con el instrumento Breast-Q® en su versión en español. Mostramos las variables cuantitativas como promedios y desviación estándar. Los datos cualitativos como frecuencias y porcentajes. El análisis del antes y después de la reconstrucción mamaria con la prueba de Wilcoxon. Tomamos como significativo un valor p <0.05. Para el análisis de los datos utilizamos el paquete estadístico SPSS versión 22. Resultados La satisfacción en cuanto a sus pezones, tórax, la información referida y en general, fue superior a 75 puntos sobre 100. De manera interesante, también el bienestar psicológico estuvo por encima del 75 de promedio. Al comparar el antes y después de la satisfacción con sus senos y del bienestar sexual encontramos un aumento significativamente estadístico. Conclusiones La evaluación mediante el instrumento Breast-Q® entre nuestro grupo de estudio demostró que la reconstrucción mamaria mejora la calidad de vida de las pacientes sometidas a este procedimiento.

RESUMO Racional: A identificação de fatores prognósticos do câncer gástrico (GC) permitiu predizer a evolução dos pacientes. Objetivo: Avaliar a confiabilidade do índice linfoparietal na predição de sobrevida em longo prazo em pacientes tratados com intenção curativa. Método: Estudo prospectivo do Hospital das Clínicas da Universidade de Chile, entre maio de 2004 e maio de 2012. Todas as operações de câncer gástrico foram com intenção curativa. Os critérios de exclusão foram: gastrectomia por lesões benignas, cânceres estágio 4, ressecções R1, procedimentos paliativos, esofagogastrectomias completas e operações de emergência. Resultados: Foi incluído um total de 284 pacientes; da amostra 65,4% eram homens, com média de idade de 64,5 anos, 75% eram cânceres avançados, 72,5% necessitaram de gastrectomia total e 30 coletas de linfonodos. A morbimortalidade cirúrgica foi de 17,2% e 1,7%. Sobrevida em cinco anos foi de 56,9%. O índice N +/T pôde predizer a sobrevida em longo prazo em todos os subgrupos (p<0,0001), embora tivesse previsão confiável em GC precoce (p=0,005), GC avançado (p<0,0001), célula GC de anel de sinete (p< 0,0001), GC proximal (p<0,0001) e GC distal (p<0,0001). As curvas ROC N +/T, LNR e T apresentaram áreas abaixo da curva de 0,789, 0,786 e 0,790, respectivamente, sem diferença estatística significativa (p=0,96 ). Conclusão: O índice N +/T é um quociente confiável no prognóstico na avaliação de pacientes com adenocarcinoma gástrico que foram ressecados com intenção curativa.

ABSTRACT Background: The identification of prognostic factors of gastric cancer (GC) has allowed to predict the evolution of patients. Aim: Assess the reliability of the lymphoparietal index in the prediction of long-term survival in GC treated with curative intent. Method: Prospective study of the Universidad de Chile Clinical Hospital, between May 2004 and May 2012. Included all gastric cancer surgeries with curative intent. Exclusion criteria were: gastrectomies due to benign lesions, stage 4 cancers, R1 resections, palliative procedures, complete esophagogastrectomies and emergency surgeries. Results: A total of 284 patients were included; of the sample 65.4% were male,mean age of 64.5 years,75% were advanced cancers, 72.5% required a total gastrectomy, 30 lymph nodes harvest. Surgical morbidity and mortality were 17.2% and 1.7%. 5-year survival was 56.9%. The N+/T index could predict long-term survival in all de subgrups (p<0.0001), although had a reliable prediction in early GC (p=0.005), advanced GC (p<0.0001), signet ring cell GC (p<0.0001), proximal GC (p<0.0001) and distal GC (p<0.0001). The ROC curves N+/T index, LNR and T classification presented areas below the curve of 0.789, 0.786 and 0,790 respectively, without a significant statistical difference (p=0.96). Conclusion: The N+/T index is a reliable quotient in the prognostic evaluation of gastric adenocarcinoma patients who have been resected with curative intent.

Introduction: One of the most important outcomes in patients undergoing body-contouring surgery is quality of life. Data on long-term quality of life is deficient. The main purpose of this study is to determine if short-term QoL after body contouring surgery maintains in the long-term follow up. Methods: A cohort study was designed; patients with at least one-year follow-up from the surgery were included. Quality of life was measured with the Body-Qol© instrument. All patients answered the preoperative Body-Qol© and at least one measurement after one year of follow-up from body contouring surgery. The preoperative scores, short-term scores and long-term follow-up scores were compared. The statistical analysis was made with Kruskal-Wallis y Kolmogorov-Smirnov tests. Results: The cohort was integrated by 112 patients; the long-term follow-up was of 75%. Quality of life improved between the preoperative measure (43.9 ± 14.1 points) and both short-term and long-term measures (85.2 ± 16.8 early postoperative y 83.6 ± 13.5 late postoperative), which was statistically significant (P< .0001). There was no difference between the short-term and long-term measures (P = .112). The domain analysis demonstrated the same tendency. Massive weight loss patients had lower preoperative scores but improved more after BCS, reaching almost cosmetic values. Conclusions: Quality of life improves soon after surgery and is stable over time. This was observed for both massive weight loss and cosmetic patients.

Introducción: La calidad de vida es uno de los resultados en cirugía de contorno corporal más importantes. La evidencia sobre la calidad de vida de estos pacientes a largo plazo es escasa. El objetivo de este estudio fue determinar si la calidad de vida obtenida en el postoperatorio temprano posterior a la cirugía de contorno corporal se mantiene a largo plazo. Métodos: Se diseñó un estudio de cohorte prospectiva compuesta por pacientes postoperados de cirugía de contorno corporal con más de un año de seguimiento. La calidad de vida fue medida con el instrumento Body-Qol®. Se compararon los puntajes preoperatorios, postoperatorios tempranos y postoperatorios tardíos. Se realizó el análisis estadístico con las pruebas de Kruskal-Wallis y Kolmogorov-Smirnov. Resultados: La cohorte se compuso de 112 pacientes con un seguimiento a largo plazo del 75%. En toda la cohorte la calidad de vida mejoró entre el preoperatorio (43,9 ± 14,1 puntos) y ambas mediciones postoperatorias (85,2 ± 16,8 postoperatorio temprano y 83,6 ± 13,5 postoperatorio tardío), siendo estadísticamente significativo (p < 0,0001). Entre el postoperatorio temprano y tardío no existió diferencia (p = 0,112). El análisis por dominios demostró la misma tendencia. Los pacientes con pérdida masiva de peso tuvieron puntajes preoperatorios menores, pero igualaron a la población estética en ambas mediciones postoperatorias. Conclusiones: La calidad de vida mejora significativamente posterior a la cirugía de contorno corporal de forma temprana, y esta mejoría es estable en el tiempo. Esto se observa tanto en los pacientes estéticos como en los posteriores a la pérdida masiva de peso.

Objective To determine the changes in the quality of life of women subjected to augmentation mammoplasty or a prosthesis mastopexy, using the validated tool Breast-Q®. Materials and methods A prospective cohorts study was conducted that included operated on for augmentation mammoplasty or augmentation mastopexy in the Hospital Clínico de la Universidad de Chile (HCUCH) between October 2013 and May 2014. The quality of life (QoL) was measured using the Breast-Q® validated tool. Descriptive and analytic statistics were performed to evaluate the overall change in QoL and by domains, considering a p<.05 as statistically significant. Results A total of 58 patients were operated on, of whom 33 (56.9%) completed the Breast-Q® questionnaire before surgery, and 25 (75.7%) of them in the post-operative period. The quality of life increased from 49.7% to 82.5% (p<.001). When analysed by domain, there was an improvement in Self-esteem (52% to 88%, p<.001), Self-image (22% to 80%, p<.001) and Sex Life (31% to 86%, p<.001). The physical symptoms increased from 75% to 94% (p<.001). Conclusions Breast augmentation improves the quality of life, in particular, self-esteem, self-image, and sex life, but physical discomforts increased. The overall satisfaction was high.
