Prevalência e fatores de risco para lipedema no Brasil / Lipedema prevalence and risk factors in Brazil

Resumo Contexto O lipedema é caracterizado por deposição anormal de gordura em glúteos e pernas bilateralmente, que pode ser acompanhada por edema, dor e sensibilidade ao toque. Ainda é frequentemente confundido com condições mais frequentes, como obesidade e linfedema. A prevalência estimada na Europa varia entre 0,06% e 39%. Objetivos Avaliar a prevalência do lipedema na população brasileira e identificar fatores de saúde relacionados a essa doença. Métodos Foi aplicado um questionário de rastreamento on-line, previamente validado em amostra representativa da população geral. O questionário de rastreamento foi distribuído e aplicado em voluntárias anônimas representativas da população geral brasileira por software dedicado a análises populacionais. Resultados Um total de 253 mulheres respondeu ao questionário, e 12,3 ± 4% (intervalo de confiança de 95%) apresentaram sintomatologia compatível com alta probabilidade de diagnóstico de lipedema. Ansiedade, depressão, hipertensão e anemia foram correlacionadas com a alta probabilidade diagnóstica da doença. Conclusões A prevalência estimada do lipedema na população de mulheres brasileiras é de 12,3%.

Abstract Background Lipedema is characterized as an abnormal deposition of fat in the buttocks and legs bilaterally that may be accompanied by swelling, pain, and tenderness. It is still often confused with more frequent conditions such as obesity and lymphedema. The estimated prevalence in Europe varies between 0.06% and 39%. Objectives To evaluate the prevalence of lipedema and identify health factors related to it in the Brazilian population. Methods Administration of a previously validated online screening questionnaire to a representative sample of the general population. The questionnaire was distributed and administered to anonymous volunteers representing the general Brazilian population using software designed for population analyses. Results 253 women answered the questionnaire, 12.3 ± 4% (Confidence Interval [CI] 95%) of whom presented symptoms compatible with a high probability of being diagnosed with lipedema. Furthermore, anxiety, depression, hypertension, and anemia were also correlated with a high probability of the diagnosis. Conclusions The estimated prevalence of lipedema in the population of Brazilian women is 12.3%.

Tratamiento supermicroquirúrgico del linfocele inguinal con linfedema intercurrente: restauración de la fisiología linfática / Supermicrosurgical approach to inguinal lymphocele with lymphedema: restoring the lymphatic physiology

Resumen Introducción: El linfocele es una patología que puede ocurrir por la disrupción linfática durante una cirugía, siendo frecuente luego de una linfadenectomía inguinal. Existen diversos enfrentamientos para prevenirlo o minimizarlo, sin embargo, los resultados son inconsistentes. Caso clínico: Reportamos el caso de una mujer, con linfocele recurrente en zona inguinal derecha y linfedema distal de la extremidad secundario a una biopsia ganglionar, tratado exitosamente mediante supermicrocirugía para restaurar el drenaje linfático. La extremidad inferior tenía un exceso de volumen de 7,03%. Se realizaron estudios preoperatorios con linfografía por resonancia magnética y linfografía con verde de indocianina para identificar los vasos linfáticos y realizar anastomosis linfático-venosas (ALV). Se identificaron tres vasos linfáticos aferentes y se realizó una capsulectomía total. Se realizaron tres ALV término-terminales supermicroquirúrgicas en zona inguinal y una ALV distal en pierna. Durante seguimiento no hubo recidiva del linfocele, evidenciándose una reducción del exceso de volumen de la extremidad afectada de un 105,26%. El linfocele inguinal y linfedema pueden ser tratados exitosamente mediante supermicrocirugía, restaurando el flujo linfático de manera fisiológica, evitando la recurrencia de linfocele y mejorando los síntomas del linfedema.

Introduction: Lymphocele may occur after the disruption of lymphatic channels during a surgical procedure. After inguinal lymphadenectomy are very common, and many different approaches have been tried to prevent or minimize the formation of lymphoceles with inconsistent results. Clinical Case: We report a case of a female patient who presented with right recurrent inguinal lymphocele and lower limb lymphedema after lymph-node biopsy that was successfully treated with lymphatic supermicrosurgery restoring the lymph flow. Lower extremity had an excess volume of 7,03% compared to the healthy contralateral limb. Preoperative study with magnetic resonance lymphangiography and indocyanine green lymphography were done to identify intraoperatively lymphocele afferent and distal lymphatic vessels to perform lymphovenous anastomosis (LVA). Three different afferent lymphatics were identified and total capsulectomy was performed. Three end-to- end supermicrosurgical LVA in the groin and one distal LVA on the leg were performed. The surgery was uneventful, and there were no postoperative complications. In the follow-up, no lymphocele was noticed and lymphedema had visibly reduced with a reduction of excess volume of 105.26%. Inguinal lymphocele and lymphedema can be successfully treated with supermicrosurgery since it is a physiological approach to restore the lymphatic flow, in order to avoid lymphocele recurrence and to improve lymphedema symptoms.

Tratamiento quirúrgico del linfedema de miembro superior postratamiento del cáncer de mama / Surgical treatment of lymphedema of the upper limb after breast cancer

Introducción. El linfedema de miembro superior postratamiento del cáncer de mama es una afección progresiva y crónica que compromete a una gran cantidad de pacientes causando efectos físicos, psicológicos y sociales. El linfedema secundario se da en un 20-40% de los casos luego de la cirugía del cáncer de mama con vaciamiento y radioterapia. Este es un problema desafiante. El tratamiento conservador ha demostrado no ser suficientemente exitoso por lo que su tratamiento quirúrgico es una buena opción. La transferencia microquirúrgica de nódulo linfático vascularizado (TNLV) brindó una nueva esperanza para este grupo de pacientes. Material y métodos. En el periodo comprendido entre marzo 2016 y agosto 2018 se analizaron 16 pacientes con una edad promedio de 50,25. Se realizó tratamiento quirúrgico basándose en la transferencia de nódulo linfático vascularizado (TNLV) de la ingle a la axila por medio de una anastomosis microquirúrgica de la arteria circunfleja ilíaca superficial en pacientes que presentaron linfedema secundario al tratamiento del cáncer de mama. Se realizó simultáneamente a la cirugía reconstructiva de la mama con colgajo libre DIEP y también en un segundo tiempo quirúrgico. Tiempo quirúrgico de 4,3 horas y una estadía en internación de 2,3 días. Resultados. La vitalidad de los colgajos fue 100%. Como morbilidad, se presentaron cuatro casos de seroma, una infección y una dehiscencia en la zona dadora. Con un seguimiento promedio de 10,43 meses y una reducción significativa de volumen del miembro afectado del 27.47% en comparación con el preoperatorio. La incidencia de celulitis descendió. La linfografía posoperatoria indicó una mejoría en el drenaje linfático del miembro afectado. Conclusiones. La transferencia linfática vascularizada al miembro afectado en conjunto con la cirugía reconstructiva mamaria DIEP es un procedimiento seguro y eficaz en el tratamiento del linfedema de miembro superior en pacientes mastectomizadas con vaciamiento ganglionar y radioterapia.

Purpose: Upper limb lymphedema post breast cancer treatment is a progressive and chronic condition that involves a large number of patients causing psychological, physical and social effects. The incidence of secondary lymphedema is about 20-40% before breast cancer treatment. This is a challenging problem. The conservative treatment has shown not to be successful enough so the surgery is a really good option. The vascularized lymph node transfer (VLNT) offers some hope to this group of patients. The purpose of the investigation is to demonstrate that te VLNT is an efficacious approach to treating postmastectomy upper limb lymphedema. Methods: From March 2016 to August 2018 were analyzed sixteen patients with a mean age of 50.25 years. They all have secondary lymphedema. They underwent surgical treatment based on vascularized lymph node transfer from the groin to the axially area or elbow as a recipent site. The deep inferior epigastric perforator flap was made at the same time, as a stacked flap. In only six cases, the VLNT was made on a second surgical time. The serrato's vessels were used as a recipient vessels in the axilary area and a radial artery branch and the cephalic vein were used in the elbow. Results: The flaps vitality was 100%. There were four seroma cases, one infection and one dehiscence. At a mean follow up of 10.43, the mean circumference reduction rate of the lymphedematous limb was about 27.47% between the preoperative and the postoperative groups. The postoperative lymphoscintigrapy showed a little improvement. The follow up of the vitality of the nodes was made by a lymphatic contrast tomography, and it showed all nodes survived. Conclusions: The vascularized lymph node transfer and the DIEP flap were confirmed as an effective and safe treatment to the secondary lymphedema in this type of patients, and it really improves postmastectomy upper limb lymphedema

Funcionalidade e qualidade de vida em indivíduos com linfedema unilateral em membro inferior: um estudo transversal / Functionality and quality of life of patients with unilateral lymphedema of a lower limb: a cross-sectional study

O linfedema de membros inferiores é uma doença crônica decorrente de dano no sistema linfático que influencia a mobilidade, a funcionalidade e a qualidade de vida dos indivíduos. Questionários e o teste físico são métodos bastante práticos, de fácil aplicação e baixo custo, que fornecem dados importantes para a avaliação desses pacientes. Objetivos Avaliar a influência do linfedema unilateral de membro inferior na funcionalidade e na qualidade de vida, correlacionando três ferramentas de avaliação. Métodos Estudo descritivo com 25 indivíduos com linfedema unilateral em membro inferior, de ambos os sexos. Foi avaliada a perimetria e foram aplicados The Medical Outcome Study Short Form-36 Health Survey (SF-36) para avaliação da qualidade de vida, Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema (Lymph-ICF-LL) para estudo das habilidades físicas, mentais e sociais relacionadas ao linfedema e o Timed Up and Go (TUG) para avaliação da funcionalidade. Resultados Houve a presença de linfedema em todo o membro inferior dos participantes. Os domínios mais prejudicados pelo linfedema foram os aspectos físicos (25,0 ± 31,4) e emocionais (36,0 ± 42,9) no SF-36 e o domínio mobilidade (6,0 ± 2,6) no Lymph-ICF-LL. O TUG foi realizado em 9,88 ± 1,98 s. Houve correlação entre o TUG e os questionários e entre os dois questionários utilizados. Conclusões Indivíduos com linfedema unilateral em membro inferior apresentam um impacto negativo na qualidade de vida e na funcionalidade avaliadas através de questionários, que correlacionam entre si. Não foi encontrada alteração no TUG, mas houve correlação entre ele e os questionários utilizados

Lymphedema of the lower limbs is a chronic disease caused by damage to the lymphatic system that influences people's mobility, functionality, and quality of life. Questionnaires and physical test are very practical, easy to apply, and low cost methods that provide important data for evaluation of these patients. Objectives To evaluate the influence of unilateral lower limb lymphedema on functionality and quality of life, correlating 3 assessment tools. Methods This was a descriptive study investigating 25 patients of both sexes with unilateral lymphedema in a lower limb. Limb volume was assessed using circumferential tape measurements, the Medical Outcomes Study Short Form-36 Health Survey (SF-36) was used to assess quality of life, the Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema (Lymph-ICF-LL) was used to assess physical, mental, and social skills related to lymphedema, and the Timed Up and Go (TUG) test was used for functional assessment. Results Lymphedema was present throughout the affected lower limb of participants. The domains most affected by lymphedema were physical aspects (25.0 ± 31.4) and emotional aspects (36.0 ± 42.9) from the SF-36 and the mobility domain (6.0 ± 2.6) from the Lymph -ICF-LL. Patients performed the TUG in 9.88 ± 1.98 seconds. The TUG was correlated with the questionnaires and the questionnaires were correlated with each other. Conclusions People with unilateral lower limb lymphedema exhibited negative impacts on quality of life and functionality, as evaluated by questionnaires, which were correlated with each other. TUG performance was within normal limits, but results correlated with the questionnaires used
