Experiencia en reconstrucción del paciente gran quemado agudo con microcirugía

Introducción: Las quemaduras son un trauma frecuente de ocurrencia en todo el mundo, que ha experimentado importantes aumentos de sobrevida. Su manejo requiere la reposición de la barrera cutánea, lo que se logra en la mayoría de los casos con el uso de injertos dermo-epidérmicos. Sin embargo, existen algunas veces lesiones complejas que no logran sanar mediante injertos, arriesgando la funcionalidad o vitalidad del área comprometida, que requerirán reparaciones complejas con el uso de colgajos microqui- rúrgicos (CM). Metodología: Estudio descriptivo retrospectivo en que incluimos todos los pacientes gran quemados agudos admitidos en Hospital de Urgencia de la Asistencia Pública, Servicio de Quemados y Rehabilitación, desde abril de 2019 hasta diciembre de 2020 los que fueron manejados con colgajo micro- quirúrgico. Revisión de ficha clínica para obtención de variables demográficas y del procedimiento con análisis de frecuencia de ocurrencia. Resultados: En nuestro período de estudio hubo 376 ingresos y 21 pacientes recibieron 25 CM. La mayoría hombres (96%), edad promedio 40 años, superficie comprometida promedio 16%, mecanismo más frecuente electricidad (64%) y fuego (32%). La ubicación más frecuente del colgajo fue en extremidades inferiores (64%) y el colgajo más utilizado fue el anterolateral de muslo (80%). Tiempo medio a reconstrucción fueron 40 días, no hubo pérdida total del colgajo. Discusión: se realizó un CM en 5,6% de nuestros ingresos, la mayoría durante el intervalo primario tardío, sin pérdidas totales. Estos resultados representan la consolidación de la técnica que permite su uso en el paciente gran quemado durante su etapa aguda, permitiendo coberturas complejas y manteniendo riesgo quirúrgico y tasa de complicaciones adecuada con enfoque en rehabilitación precoz.

Introduction: Burns are the fourth most common trauma. Microsurgery has evolved as a valuable tool in the acute setting allowing early closure of complex wounds in order to avoid infection, maintain function or even for limb salvage in one stage reconstruction. We present our experience at our burn center in Chile. Method: We performed a retrospective analysis of all major burn patients admitted in the National Burn Center in Chile who received a microsurgical flap in the period between April 2019 to December 2020. Results: A total of 21 patients had 25 free flaps. All patients but one were male (96%), mean age 40 years (range 20-69 years). Total body surface area means 16% (range 1-64%). Most of the injuries were caused by high voltage electricity (64%) and fire (32%). 64% were performed in lower limbs and 36% in upper limbs. In 80% of the cases, anterolateral thing flap was chosen. Mean time to reconstruction was 40 days. We didn't experience a total flap lost in this series. Discussion: In the acute phase microsurgery proved to be safe and feasible albeit a small surgical indication. We performed a flap in 5.6% of our admissions, mostly during late primary interval with no flaps lost. Our results acknowledge the consolidation of the technique for its use in the acutely burned setting, allowing complex coverage while maintaining the surgical risk and an internationally acceptable rate of losses and complications.

Cambios en la calidad de vida en mujeres sometidas a aumento mamario: resultados preliminares de un estudio de cohortes / Changes in quality of life in women subjected to augmentation mammoplasty: preliminary results of a cohort study

Objetivo Determinar los cambios en calidad de vida en mujeres sometidas a mamoplastia de aumento o mastopexia con prótesis, usando el instrumento validado Breast-Q®. Materiales y métodos Estudio de cohortes prospectivo. Se incluyeron todas las pacientes operadas de mamoplastia de aumento o mastopexia de aumento en el Hospital Clínico de la Universidad de Chile entre octubre de 2013 y mayo de 2014. La calidad de vida (CdV) se midió con el instrumento validado Breast-Q®. Se realizó estadística descriptiva y analítica para evaluar el cambio global en CdV y por dominios considerando estadísticamente significativo un valor p < 0,05. Resultados En el periodo estudiado se operaron 58 pacientes, 33 (56,9%) completaron el instrumento Breast-Q® en el preoperatorio y 25 (75,7%) de ellas en el postoperatorio. La CdV subió de un 49,7% a un 82,5% (p < 0,001); analizando por dominio hubo mejoría en autoestima (52% a 88%, p < 0,001), autoimagen (22% a 80%, p < 0,001) y vida sexual (31% a 86%, p < 0,001). Los síntomas físicos empeoraron desde un 94% a 75% (p < 0,001). Conclusiones El aumento mamario mejora la CdV, específicamente la autoestima, la autoimagen y la vida sexual, pero las molestias físicas aumentan. La satisfacción global fue alta.

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.

The Body-QoL(®): patient reported outcomes in body contouring surgery patients [corrected].

BACKGROUND: This study aimed to design a new patient-reported outcome (PRO) instrument to measure patient satisfaction after body-contouring procedures such as liposculpture, abdominoplasty, body-lift, thigh-lift, and arm-lift. METHODS: Phase 1a involved an extensive literature review, 16 in-depth patient interviews, and expert focus groups with 5 plastic surgeons to develop a conceptual framework for the outcomes deemed important for body image and preliminary PRO instruments. In phase 1b, the preliminary instrument was tested with a second independent sample of 29 patients with whom simple interviews were additionally performed. In the second sample, scale reliability was calculated. RESULTS: In phase 1a, the domains identified for the conceptual framework included clothing and body image, sexual and affective life, self-image and self-esteem, social relationships, and physical symptoms. In phase 1b, the scale internal consistency was 91.5 %. CONCLUSIONS: When psychometric evaluation is completed, the Body-Shape-Related Quality of Life instrument and its subscales will provide a reliable tool for plastic surgeons, researchers, and patients to use in measuring the impact and effectiveness of body-contouring procedures from the patient's perspective.
