Estadiaje ganglionar en el adenocarcinoma gástrico / Lymph node stage in gastric adenocarcinoma

Resumen Objetivos: El sistema linfático del estómago es complejo y multidireccional, siendo difícil predecir el patrón de diseminación linfática en el adenocarcinoma (ADC) gástrico. Los objetivos de este trabajo son determinar si el analizar los grupos ganglionares de la pieza quirúrgica por separado tiene implicaciones en el estadiaje, además estudiar la afectación de diferentes grupos ganglionares. Materials y Método: Estudio observacional retrospectivo de pacientes intervenidos de gastrectomía y linfadenectomía con intención curativa por ADC en un hospital de referencia (2017-2021).,_Se han comparado aquellos pacientes cuya pieza quirúrgica se estudió en su totalidad (grupo A) con aquellos en los que se separaron los grupos ganglionares para su análisis (grupo B). En el grupo B, se ha analizado la afectación ganglionar de diferentes grupos ganglionares en base a la localización tumoral y el estadio pT. Resultados: Se incluyeron 150 pacientes. La media de ganglios analizados fue significativamente mayor cuando se separaron los grupos ganglionares (grupo B) (24,01 respecto a 20,49). La afectación ganglionar fue del 45,8%, 58,3% y 55,5% en los tumores de tercio superior, medio e inferior respectivamente, y los grupos difirieron en base a la localización tumoral. El riesgo de afectación ganglionar fue significativamente mayor y hubo más grupos ganglionares perigástricos afectos cuanto mayor era el estadio pT. Conclusiones: Separar los grupos ganglionares previo a su análisis aumenta el número de ganglios analizados mejorando el estadiaje ganglionar. Existen diferentes rutas de drenaje linfático dependiendo de la localización tumoral y la afectación ganglionar aumenta de forma paralela al estadio pT.

Objectives: The lymphatic system of the stomach is complex and multidirectional, making it difficult to predict the pattern of lymphatic spread in gastric adenocarcinoma (GAC). The aim of this paper is to determine if analyzing the lymph node groups of the surgical specimen separately has implications in the pathological staging, as well as to study the involvement rate of different lymph node groups. Material and Method: Retrospective observational study of patients who underwent curative intent gastrectomy and lymphadenectomy for GAC in a reference hospital (2017-2021). Those patients whose surgical specimen was studied as a whole (group A) were compared with those in whom the lymph node groups were separated by surgeons before analysis (group B). In group B, the involvement of different lymph node groups was analyzed based on tumor location and pT stage. Results: 150 patients were included. The mean number of lymph nodes analyzed was significantly higher when the lymph node groups were separately analyzed (group B) (24.01 compared to 20.49). Lymph node involvement was 45.8%, 58.3%, and 55.5% in tumors of the upper, middle, and lower third, respectively, and the involved groups differed depending on the tumor location. The higher the pT stage was, the risk of lymph node involvement was significantly higher and there were more perigastric lymph node groups affected. Conclusions: Separating lymph node groups prior to their analysis increases the number of lymph nodes analyzed and therefore improves lymph node staging. There are different lymphatic drainage routes depending on the tumor location and lymph node involvement increases in parallel with the pT stage.

Esofagectomía con linfadenectomía guiada por fluorescencia con verde de indocianina en cáncer de esófago. Experiencia inicial en la Argentina / Esophagectomy with lymphadenectomy guided by fluorescence imaging with indocyanine green in esophageal cancer. Initial experience in Argentina

RESUMEN Antecedentes: en la última década ha comenzado a investigarse el uso de la captación de fluorescencia mediante luz infrarroja para la visualización de ganglios linfáticos en tumores de estómago y esófago. Objetivo: evaluar la factibilidad de la evaluación del drenaje linfático de cáncer de esófago mediante el uso de fluorescencia y verde de indocianina (ICG). Material y métodos: se realizó un estudio prospectivo que incluyó pacientes con tumores de la unión gastroesofágica resecables (estadios I, II y III). Antes de comenzar la cirugía se inyectaron por endoscopia 4 mL de ICG doblemente diluida en agua estéril (1,25 mg/mL = 5 mg) en la submucosa del esófago en los cuatro cuadrantes (1 mL por cuadrante) alrededor del tumor. Resultados: se incluyeron en total 6 pacientes. En todos ellos se logró identificar el drenaje linfático del tumor hacia la primera estación ganglionar: en 6/6 (100%), el drenaje linfático con fluorescencia se detectó en las estaciones ganglionares N°s 3 y 7 (curvatura menor y arteria gástrica izquierda). En ningún paciente se identificó fluorescencia en ganglios mediastinales. Conclusión: la visualización del drenaje linfático de tumores de la unión gastroesofágica mediante el uso de fluorescencia con ICG es factible.

ABSTRACT Background: Over the past decade, fluorescence imaging with infrared light has been used to visualize lymph nodes in tumors of the stomach and esophagus. Objective: The aim of our study was to evaluate the feasibility of evaluating lymphatic drainage in esophageal cancer using fluorescence and indocyanine green (ICG). Material and methods: We conducted a prospective study of patients with resectable tumors of the gastroesophageal junction (stage I, II and III). Before surgery, 4 mL of ICG double diluted in sterile water (1.25 mg/mL = 5 mg) were injected via endoscopy into the esophageal submucosa in the four quadrants (1 mL per quadrant) around the tumor. Results: A total of 6 patients were included. Lymphatic drainage from the tumor to the first lymph node station was identified in all patients: in 6/6 (100%), fluorescent lymphatic drainage was detected in nodal stations number 3 and 7 (lesser curvature and left gastric artery) Fluorescence was not identified in the mediastinal lymph nodes in any patient. Conclusion: Visualization of lymphatic drainage of gastroesophageal junction tumors to the lesser curvature nodes using fluorescence imaging is feasible.

Prevención del linfedema posquirúrgico en cáncer de mama mediante rehabilitación fisioterapéutica: estudio comparativo entre drenaje linfático manual y kinesiotape / Prevention of postsurgical lymphedema in breast cancer through physiotherapeutic reha- bilitation: a comparative study between manual lymphatic drainage and kinesiotape

Se realizó un estudio con diseño cuantitativo, de tipo observacional descriptivo; cuya población de estudio estuvo constituida por 142 pacientes de sexo femenino, diagnosticadas con cáncer de mama en la Unidad Oncológica Solca-Chimborazo, durante el período 2014-2019; con el objeti - vo de describir el tratamiento fisioterapéutico en ese contexto de investigación. Los datos fueron recolectados a partir de las respectivas historias clínicas. A partir de 2015, se observó un predo- minio de pacientes adultos con edades comprendidas entre 36 y 65 años. De las 142 pacientes que conformaron la población estudiada, solo 5 desarrollaron linfedema posquirúrgico. La mayoría de las pacientes incluidas en el estudio fueron intervenidas quirúrgicamente (65); 59 de las cuales recibieron tratamiento de drenaje linfático manual. Entre la población elegida en la Unidad Oncológica de Solca-Chimborazo se evidenció que la aplicación de terapia de rehabili - tación mediante drenaje linfático manual posquirúrgico reduce la posibilidad de aparición de linfedema a largo plazo.

This research aimed to describe the physiotherapeutic treatment in this research context. A study was carried out with a quantitative design, of a descriptive observational type. The study popula- tion consisted of 142 female patients, diagnosed with breast cancer at the Solca-Chimborazo Oncology Unit, during the period 2014-2019. The data were collected from the respective medi- cal records. Since 2015, a predominance of adult patients aged between 36 and 65 years was observed. From the 142 patients that made up the study population, only 5 developed postsurgi- cal lymphedema. Most of the patients included in the study underwent surgery (65); 59 received manual lymphatic drainage treatment. Among the population chosen in the Solca-Chimborazo Oncology Unit, it was evidenced that the application of rehabilitation therapy through postope- rative manual lymphatic drainage reduces the possibility of long-term lymphedema develop - ment.

Efetividade da drenagem linfática manual associada a bandagem funcional na melhora clínica do fibro edema gelóide em gestantes: ensaio clínico, controlado e randomizado / Effectiveness of manual lymphatic drainage associated with functional banding in the clinical improvement of gynoid lipodystrophy in pregnant women: a clinical, controlled and randomized trial

No período gestacional, mulheres podem desencadear disfunções hormonais que induzem ao acúmulo de edema e nódulos fibróticos, favorecendo a formação de relevos cutâneos ocasionando sensação dolorosa. Sendo assim, este estudo visou comparar a efetividade da drenagem linfática manual com ou sem o uso da bandagem funcional no fibro edema gelóide (FEG) em gestantes no segundo e terceiro trimestre gestacional. Trata-se de um ensaio clínico randomizado, composta por três grupos: G1: Drenagem Linfática Manual (DLM); G2: DLM + Bandagem Funcional (BF); G3: Grupo Controle. Critério de inclusão: gestantes no segundo e terceiro trimestre, primípara e multípara e gestação de feto único. Realizou-se a DLM na região dos glúteos e membros inferiores e a BF aplicada da região inguinal em forma de teia direcionada a região medial dos glúteos, usando uma tensão superficial de 10%. Utilizou-se um protocolo de avaliação do fibro edema gelóide (PAPEG), anamnese, exame físico com inspeção, teste de preensão, teste de sensibilidade tátil (monofilamento de semmes ­ weinstein), avaliação da sensibilidade, grau, dor, recomendação e satisfação da paciente. Foram realizadas fotos da região do glúteo do antes e depois e avaliadas por 10 especialistas através da fotogrametria. Observou-se uma melhora clínica significativa no grupo drenagem e na associação com a bandagem quando comparado ao grupo controle pelos 10 especialistas. Houve uma melhora significativa nas notas dos especialistas nos grupos G1 e G2, quando comparado ao G3. Portanto, o presente estudo demonstrou uma melhora clínica no fibro edema gelóide das gestantes que receberam a DLM isolada, e na associação com a BF, quando comparado ao grupo controle.

During pregnancy, women can trigger hormonal dysfunctions that induce the accumulation of edema and fibrotic nodules, favoring the formation of rifted skin causing a painful sensation. Therefore, this study aimed to compare the effectiveness of manual lymphatic drainage with or without the use of functional bandages in gynoid lipodystrophy (GLD) in pregnant women in the second and third trimester. This was a randomized clinical trial, composed of three groups: G1: Manual Lymphatic Drainage (MLD); G2: MLD + Functional Bandage (FB); G3: Control Group. Inclusion criteria: pregnant women in the second and third trimester, primiparous or multiparous and a single fetus pregnancy. MLD was performed in the gluteal region and lower limbs, and FB was applied from the inguinal region in the form of a web directed to the medial gluteal region, using a surface tension of 10%. An evaluation protocol for gynoid lipodystrophy (EPGLD) with anamnesis, a physical examination with an inspection, a grip test, tactile sensitivity test (Semmes-Weinstein monofilament test), assessing the patient's sensitivity, grade, pain, recommendation, and satisfaction was used. Photos were taken of the gluteus region before and after and were then evaluated by 10 specialists through photogrammetry. There was a significant clinical improvement in the drainage group and in the association with the bandage when compared to the control group by the 10 specialists. There was a significant improvement in the scores of specialists in groups G1 and G2, when compared to G3. Therefore, the present study demonstrated a clinical improvement in gynoid lipodystrophy of pregnant women who received MLD alone, and in association with FB, when compared to the control group.

Observouse que 63.5% relataram que realizou a abdominoplastia por flacidez de pele, 53.3% realizaram a abdominoplastia associada à lipoaspiração, 61% relataram que não realizaram procedimentos pré-operatórios, 59.9% relataram não saber se havia fisioterapeuta no centro cirúrgico durante o intraoperatório, 70.6% das pacientes realizaram procedimentos pós-operatórios, sendo 37.4% com fisioterapeuta, a complicação mais comum foi edema representando 84.2%. Conclusão: A principal indicação para a abdominoplastia foi por flacidez de pele, sendo mais frequentemente associada à lipoaspiração. A maior parte das pacientes não realizou procedimentos pré-operatórios e realizou pós-operatório iniciado após 1 a 3 dias, com fisioterapeuta, por indicação de um conhecido, com frequência de três vezes na semana, pela queixa de edema, sendo que os procedimentos mais realizados foram a drenagem linfática manual e o ultrassom terapêutico.

Introduction: abdominoplasty is the third most performed cosmetic surgery in Brazil. Its surgical planning involves the pre, intra, and postoperative moments with the performance of several specialized professionals. Therefore, the objective of this study was to analyze the patients' perception of their professional performance and the procedures performed before, during, and after the abdominoplasty. Methods: This is a cross-sectional and observational study. Data collection was done through an online questionnaire made available digitally to women aged between 18 and 60 years, who underwent abdominoplasty in the last 12 months. Results: A total of 376 patients answered the questionnaire; however, 22 were excluded, totaling 354 questionnaires answered. It was observed that 63.5% reported having undergone abdominoplasty due to skin flaccidity, 53.3% had undergone abdominoplasty associated with liposuction, 61% reported that they had not undergone preoperative procedures, 59.9% reported not knowing whether there was a physiotherapist in the operating room during the intraoperative period. , 70.6% of the patients underwent postoperative procedures, 37.4% of whom were physiotherapists, the most common complication being edema representing 84.2%. Conclusion: The main indication for abdominoplasty was sagging skin, which is most often associated with liposuction. Most of the patients did not undergo preoperative procedures. They were performed after 1 to 3 days after the operation, with a physiotherapist, on the advice of an acquaintance, often three times a week, due to the complaint of edema. The most performed procedures were manual lymphatic drainage and therapeutic ultrasound.

Breast state improvement by using the lymphatic drainage disposable bra pads

Background: The health and good esthetic conditions of the breast are important indicators of women’s life quality. One factor that negatively affects this quality is the breast ptosis, associated with the sagging of the mammary glands due to tissue stretching and the loss of tissue and skin elasticity. New tools and methods able to improve the shape and beautiful contour of the breast are highly desirable.Methods: We investigated how the disposable bra pads by BAE International Inc., having the lymphatic drainage effect for the breast, influenced the female breast state. We applied two methods, the ultrasound elasticity imaging and the pattern recognition of the nipples position, to monitor the breast state dynamics in two groups of females, the study and control ones.Results: Preliminary results showed that both the breast elasticity and the pattern of nipple positions improved for females wearing the bra pads as compared to females wearing regular bras without pads (P<0.05 for the difference between the two groups of females).Conclusions: Overall, the bra pads by BAE can be considered as an effective tool encouraging metabolism by improving the flow of blood circulation and lymph in the breast.

Lower rectal lymphatic drainage and necessity of lateral lymph node dissection for low rectal cancer / 中国实用外科杂志

There are three lymphatic drainage pathways in lower rectal cancer,including upper,lower and lateral lymphatic drainage pathway. Lateral metastasis of rectal cancer caused by lateral lymphatic drainage pathway is an important cause of pelvic recurrence. Evidence-based medical evidence shows that preoperative concurrent chemoradiotherapy and radiotherapy can not completely kill the lymph node metastasis to the lateral side,and the positive residual rate is more than 60%. For cases with lateral lymph node metastasis after preoperative concurrent chemoradiotherapy,surgical removal of metastatic lymph nodes is the most important treatment,even the only way for patients to achieve long-term survival. Strictly grasping the indications of lateral clearance surgery to improve the positive coincidence rate of pathology,and implementing standard clearance to reduce the incidence of surgical complications through precise operation are expected to bring double benefits of local control and prolonged survival to patients with lateral metastasis of rectal cancer.

Uso da terapia por ondas de choque para o tratamento do linfedema associado ao câncer de mama: uma revisão sistemática / Use of shockwave therapy for the treatment of lymphedema associated to breast cancer: a systematic review

O linfedema associado ao câncer de mama é causa de prejuízo significativo da qualidade de vida deste grupo de pacientes e constitui complicação frequente das intervenções necessárias nesse tipo de câncer. Sabe-se que o tratamento utilizado no linfedema associado ao câncer de mama envolve a Terapia Física Complexa (TFC), cuja eficácia é limitada e não atua diretamente na patogênese dessa comorbidade. Conforme já demonstrado em alguns estudos, o uso da Terapia por Ondas de Choque (TOC) demonstra-se potencialmente benéfico para reduzir o linfedema pela indução de neoangiogênese e linfangiogênese. Objetivo: Avaliar o impacto da TOC no tratamento do linfedema associado ao câncer de mama comparado ao uso da TFC. Métodos: Foram utilizadas as seguintes bases de dados: PubMed/MedLine; BIREME; LILACS; The Cochrane Library e EMBASE, e através de busca manual de artigos. Adotou-se o método de pesquisa PICO e os descritores MeSH ajustados conforme a respectiva base de dados. Resultados: Foram encontrados um total de 262 artigos e selecionados por leitura do título ou resumo um total de 17 estudos. Seis foram excluídos por serem duplicatas, totalizando 11 artigos eleitos para verificação dos critérios de inclusão. Destes, nenhum artigo atendeu ao delineamento da metodologia proposta para esta revisão. Três deles se destacaram por se aproximarem mais da temática proposta e foram discutidos. Conclusão: É necessária a realização de estudos com qualidade metodológica adequada para avaliar o potencial benefício do uso da TOC, visando contribuir para a composição de um tratamento mais eficaz, seguro e que atue na patogênese da doença.

Lymphedema associated with breast cancer is a cause of significant impairment of the quality of life and is a frequent complication of the necessary interventions in this type of cancer. It is known that the treatment used in lymphedema associated with breast cancer involves Complex Physical Therapy (CPT), whose efficacy is limited and does not act directly in the pathogenesis of this comorbidity. As demonstrated in some studies, the use of Shock Wave Therapy (TSWT) is potentially beneficial in reducing lymphedema by inducing neoangiogenesis and lymphangiogenesis. Objective: To evaluate the impact of TSWT on the treatment of lymphedema associated with breast cancer compared to the use of CPT. Methods: The following databases were used: PubMed / MedLine; BIREME; LILACS; The Cochrane Library and EMBASE, and through manual article search. We adopted the PICO search method and the Mesh descriptors were adjusted according to the respective database. Results: A total of 262 articles were found and selected by reading the title or abstract a total of 17 studies. Six were excluded because they were duplicates, totaling 11 articles elected to verify the inclusion criteria. Of these, no article met the outline of the methodology proposed. Three of them were closer to the proposed theme and were discussed. Conclusion: It is necessary to carry out studies with adequate methodological quality to evaluate the potential benefit of the use of TSWT, in order to contribute to the composition of a more effective and safe treatment, that acts in the pathogenesis of the disease.

Manejo del cáncer de cabeza y cuello: ¿radioterapia a quién, cuándo y por qué? / Management of head and neck cancer: when, why, and to whom give radiotherapy

Revisión del enfrentamiento del paciente con cáncer escamoso de la vía aerodigestiva superior, orientada a la radioterapia. Las principales alternativas de tratamiento para los pacientes con cáncer escamoso de cabeza y cuello son la cirugía y la radioterapia (RT). La planificación del tratamiento debe considerar el tumor primario y la diseminación linfática cervical. La enfermedad subclínica es significativa en este grupo de pacientes. Cuando ésta es mayor a 20%, la disección cervical electiva ha mostrado mejorar la sobrevida libre de enfermedad y la sobrevida global. La RT por Intensidad Modulada (IMRT) permite mayor protección de los tejidos vecinos. El fenómeno de repoblación acelerada implica que dosis insuficientes o períodos largos de interrupción traducen persistencia o recidiva tumoral. Por esta razón, la adyuvancia con RT debe iniciarse precozmente. Para esto, es fundamental una evaluación dental oportuna. Los efectos adversos de la RT se dividen en agudos y tardíos, pudiendo estos últimos presentarse meses o años posterior a la terapia. Los pacientes con indicación de RT deben ser derivados tempranamente y con previa evaluación dental. La IMRT es una excelente herramienta terapéutica cuando es correctamente indicada y aplicada. Los principales beneficios en relación a la cirugía son menor morbilidad y mejor costo-efectividad por lo que suele ser la terapia de elección en enfermedad localizada y una alternativa a la disección cervical electiva.

Radiation therapy for squamous cell carcinoma of the upper aerodigestive tract: review of management. Head and neck cancer treatment includes several treatment options. Surgery and radiotherapy are the most important local treatments. When planning the local treatment, the choices for the primary tumor, and the lymphatic spread to the neck must be considered. Subclinical metastatic disease to the neck is present in about 20% of patients, and can be controlled equally with surgery or radiation therapy. In a randomized trial, elective neck dissection has been shown to improve disease-free, and overall survival when compared with observation and salvage. Intensity-modulated radiotherapy (IMRT) allows a better sparing of normal tissues in the neck, and less morbidity from the treatment. Accelerated repopulation is a main determinant of poor local control in patients treated with radiotherapy who undergo treatment interruptions or a delay in its start. Thus, adjuvant radiotherapy must begin as early as possible, within six weeks of resection. Irradiated patients are at significant risk of dental complications, even when IMRT is used. That makes mandatory a dental evaluation and treatment prior to radiotherapy. Adverse radiation effects can occur during treatment (early reactions), or months to years after completion (late reactions). Patients with indication of radiotherapy must be referred early, preferably after dental evaluation. IMRT is an excellent tool when correctly indicated and uses. Main benefits of elective neck irradiation are less morbidity and higher cosst-effectiveness, making it a very useful treatment alternative to elective neck dissection in patients with localized disease.

Effect of Manual Lymphatic Drainage on Preventing Postoperative Axillary Web Syndrome of Breast Cancer / 中国康复理论与实践

Objective To explore the effect of manual lymphatic drainage on prevention of postoperative axillary web syndrome of breast cancer. Methods From June to December, 2015, 400 breast cancer patients after modified radical mastectomy were randomly divided into control group (n=200) and intervention group (n=200). The control group accepted routine functional exercise on affected upper limbs, while the intervention group accepted manual lymphatic drainage in addition. The incidence of axillary web syndrome in both groups was compared one, two and three months after operation. Results The incidence of axillary web syndrome was less in the intervention group than in the control group in all the time points after operation (χ2>6.17, P<0.05). Conclusion Manual lymphatic drainage can effectively pre-vent axillary web syndrome in patients with breast cancer after modified radical mastectomy.

Linfadenectomia inguinoilíaca laparoscópica, após impregnação linfática com diferentes marcadores em cadelas hígidas / Laparoscopic inguinoiliac lymphadenectomy following staining using different lymphatic markers in healthy dogs

RESUMO: O sistema linfático mamário de animais saudáveis e neoplásicos é pouco estudado. Inexistem respostas detalhadas quanto ao padrão de comunicação entre as cadeias linfáticas mamárias com as abdominais e pélvicas em animais sadios ou com neoplasmas na referida glândula. Por essa razão, pretendeu-se avaliar a ocorrência dessa comunicação linfática intrabdominal, verificando também se a cadeia linfática inguinoilíaca poderia ser adequadamente abordada via cirurgia laparoscópica. Para tanto, os animais foram distribuídos, de forma randômica, em três grupos cirúrgicos: pacientes submetidos à técnica de coloração linfática com o corante azul de metileno estéril (G1); animais submetidos à técnica de impregnação linfática com o corante verde de indocianina (G2); animais submetidos à técnica demarcação linfática, utilizando solução fisiológica de NaCl a 0,9% (G3). Em todos os grupos, foi realizada a aplicação intradérmica, do corante ou solução fisiológica, ao redor da mama inguinal direita, em tempos distintos de 12h ou 30min, antes da incisão de pele. Após, foram coletadas, por videolaparoscopia, duas regiões contendo tecido adiposo, laterais às artérias ilíacas interna e externas, buscando avaliar a presença e o número de linfonodos extirpardos. Por último, realizou-se a ovário-histerectomia eletiva pelos mesmos portais de acesso. Foram considerados ainda, o tempo de cirurgia e as complicações e dificuldades técnicas trans e pós-operatórias. A técnica proposta de linfadenectomia inginoilíaca intrabdominal não obteve êxito na coleta de linfonodos. As técnicas de marcação linfática realizadas, utilizando tanto o azul de metileno a 1%, como o verde de indocianina a 1%, não evidenciaram nenhuma marcação transoperatória nos tempos estudados. Em relação às complicações e dificuldades técnicas trans e pós-operatórias, observou-se, em todos os animais, reações de hipersensibilidade cutânea ao uso dos corantes. As técnicas propostas não apresentaram maiores dificuldades de execução ou complicações transoperatórias.

ABSTRACT: The lymphatic mammary system in healthy and neoplastic animals has been poorly studied. There is sparse information regarding the communication pattern along the mammary lymphatic chain and abdominal and pelvic lymph nodes in healthy animals or in those bearing mammary neoplasms. Thus, the purpose of this study was to evaluate the occurrence of such intra-abdominal lymphatic communications, as well as the feasibility of laparoscopic assessment of the inguinoiliac lymphatic chain. Animals were randomly divided into three groups: dogs that underwent lymphatic staining with sterile methylene blue solution (G1); lymphatic staining with indocyanine green dye (G2); placebo subjects were submitted to the same injection technique, but using sterile normal saline (G3). In all groups, intradermal administration of dye or saline around the right inguinal mammary gland was performed 12 hours or 30 minutes before skin incision. Afterwards, two areas containing adipose tissue were sampled laparoscopically, lateral to the external and internal iliac arteries, and the number of lymph nodes retrieved was assessed. Animals were submitted to ovariohysterectomy using the same laparoscopic approach, following adipose tissue/lymph node excision. Other assessments included operative time, intra and postoperative complications and technical difficulties. The proposed technique for intra-abdominal iliac lymphadenectomy was not successful in recovering lymph nodes. The lymphatic staining technique using either methylene blue or indocyanine green provided no intraoperative staining. Regarding the complications and technical difficulties, all animals presented mild hypersensitivity reactions regardless of the dye used. Laparoscopy for inguinoiliac lymph node exploration presented no other technical difficulties or postoperative complications.

The progress of internal mammary lymphatic drainage and internal mammary lymph node biopsy in breast cancer / 中华内分泌外科杂志

There are two main lymphatic drainage routes of the breast: a superficial system and a deep system, and only the deep one can drain into the internal mammary lymph node (IMLN) which receive about 25%of the lymph of the breast. As one of the important nodal sites of lymphatic spread of breast, IMLN is important for neoplasm staging and it will guide adjuvant radiotherapy. However, there still lack an effective and feasible minimally invasive diagnosis technology of IMLN, leading to inaccurate staging and over/under-treatment. The“modified injection technique” broke through the bottle-neck of the low internal mammary visualization rate with traditional injection technique, and made the internal mammary sentinel lymph node biopsy possible to be a min-imally invasive assessment for IMLN status, and further guided internal mammary radiotherapy (IM-RT). Patients with IMLN positive should accept IM-RT, with IMLN negative can avoid IM-RT. With the unceasing progress in studies on internal mammary lymph drainage area, patients may obtain the individualized diagnosis and treat-ment. The review summarizes current knowledge on the anatomy and physiology of the lymphatic system of the breast to translate this into implications for clinical practice of IM-SLNB.

Mechanisms Behind the Therapeutic Effects of Er Chen Combined with Tao Hong Si Wu Tang (ECSWT) on Rheumatoid Arthritis / 世界科学技术-中医药现代化

Rheumatoid arthritis (RA) is a chronic autoimmune disorder primarily occurred in small joints.Our previous studies suggested that sufficient lymphatic drainage was favorable for the recovery of RA.This study aimed at exploring the effect of Er Chen combined with Tao Hong Si Wu Tang (ECSWT) on RA in TNF transgenic (TNF-Tg) mice.Ten-week old TNF-Tg mice and WT littermates were detected with indocyanine green-nearinfrared (ICG-NIR) lymphatic imaging system before and after accepting the 12-week intragastric administration of ECSWT.All ankle joints were assessed by micro-CT scanning.According to three dimensional images of Micro-CT,it was found that the ankle joints in the TNF-Tg group were much eroded compared with the control group.The bone mass and structure were protected after the treatment of ECSWT.ICG-NIR results showed that lymphatic clearance rate of the TNF-Tg group decreased compared with those of the control group.In comparison with the TNF-Tg group,ECSWT promoted the repair of lymphatic function.Compared with the control group,the pulse value of the TNF-Tg group declined;while this condition could be rescued by ERSWT.In conclusion,ECSWT mitigated bone erosion of astragalus bone area in TNF-Tg mice in contrast to the saline mice,while promoted the pulse value and clearance of lymphatic vessels afferent from footpad to popliteal lymph node,implying that ECSWT was a promising agent for treating RA through its promoting lymphatic drainage function effects.

Effect of Resistance Breathing Training on Breast Cancer Related Lymphedema / 中国康复理论与实践

@#Objective To observe the effect of resistance breathing training on breast cancer related lymphedema. Methods Sixty breast cancer patients with lymphedema after operation from October, 2013 to April, 2015 were randomly divided into control group (n=30) and experiment group (n=30). The control group received routine rehabilitation and manual lymphatic drainage, while the experiment group received resistance breathing training in addition, for four weeks. Their flow of lymph was measured with emission computer tomography (ECT), and their upper arm circumferences were measured, their upper limb volumes were measured with water displacement before and after treatment. Results The flow of lymph increased in both groups after treatment (t>3.446, P<0.05), while the difference of bilateral upper arm circumferences (t>2.143, P<0.05) and upper limb volumes (t>1.562, P<0.05) reduced, and all the indices improved more in the experiment group than in the control group (t>1.982, P<0.05). Conclusion Resistance breathing training may increase the back flow of lymph, to relieve the lymphedema of injured extremity.

Lipedema: A Clinical Challenge-revisited.

Lipedema is a disfiguring disorder with abnormal and progressive deposition of adipose tissue in the hips and lower extremities almost exclusively occurring in women. There is a hereditary tendency and a substantial variability in disease severity. Lipedema is often misdiagnosed as lymphedema or morbid obesity. The etiology and pathogenesis are not understood. Early diagnosis and treatment are critical to minimize physical and psychological morbidity. The diagnosis is usually made by history and clinical examination. Non-invasive imaging techniques such as computed tomography or magnetic resonance can differentiate lipedema from other causes of edematous lower extremities. Lymphoscintigraphy may be helpful in cases which are associated with lymphedema (lipo-lymphedema). Management with manual lymphatic drainage and compression therapy are considered the most appropriate treatment. Use of conventional liposuction is controversial since it may further damage the lymphatic vessels. Newer techniques such as tumescent micro annular laser assisted liposuction and water jet-assisted liposuction have shown some promising results. Variety of other surgical procedures combined with manual lymphatic drainage and tailored post-surgical care are under investigation.

Linfadenectomia laparoscópica em cadela com neoplasia mamária / Laparoscopic lymphadenectomy in a bitch with breast cancer

A linfadenectomia laparoscópica é realizada de forma rotineira na medicina, contudo é pouco utilizada na veterinária. Neste relato, um canino fêmea apresentando tumores na cadeia mamária esquerda (M4 e M5), foi submetido à aplicação intradérmica do azul de metileno estéril, ao redor do maior tumor (M5), buscando-se demarcação dos vasos linfáticos e linfonodos regionais. Após 15 minutos, iniciou-se a linfadenectomia abdominal videolaparoscópica na região inguinal esquerda, seguida da ovário-histerectomia (OVH) lapararoscópica com três portais. Realizou-se ainda mastectomia total unilateral esquerda. Pela histologia, obtiveram-se dois linfonodos abdominais livres de células tumorais. A paciente não apresentou recidiva em 60 dias.

The laparoscopic lymphadenectomy is routinely performed in medicine, but not in veterinary medicine. This report describes a case of female canine with tumors in the left mammary chain (M4 and M5), which was subjected to intra-dermal application of sterile methylene blue, around the largest tumor (M5) which tried to demarcate the lymphatic vessels and regional lymph nodes. After 15 minutes, laparoscopic lymphadenectomy involving the abdominal in the left pelvic region started, followed by laparoscopic ovariohysterctomy (OVH) using three portals access. It was also performed an unilateral left total mastectomy. For histology, two abdominal lymph nodes were free of tumor cells. The patient had no recurrence in 60 days.

Direct Effect of Manual Lymphatic Drainage in Lymphedema / 日本温泉気候物理医学会雑誌

Background: Lymphedema, which is classified into primary and secondary origin, affects more than 100.000 patients in Japan. The cause for primary lymphedema—including that of congenital origin—is yet unknown. Secondary lymphedema mostly results due to an obstruction of lymph flow caused by surgery or radiotherapy for cancer. Complex Physical Therapy (CPT) has been determined as the standard therapy for lymphedema treatment by the International Society of Lymphology (ISL). CPT comprises skin care, manual lymphatic drainage (MLD), compression and exercises, which only administered in combination results in a maximum treatment effect. At present only prophylactic instructions for cancer patients and reimbursement of fees for compression garments or bandages are part of the health care insurance in Japan. MLD is not covered by insurance. This study was conducted with the aim to prove the effect of MLD as a single-modality therapy and to contribute to the process of getting MLD covered as health care insurance treatment. Methods: In 72 patients (mean age 60.46±13.00 years) with lymphedema of the extremities only, MLD was administered for 45 minutes in upper extremities and 60 minutes in lower extremities. Treatment effect was examined through measurement of volume change of the affected side before and after treatment. Data was processed statistically by normal distribution and Wilcoxon signed rank test. Result: Edema volume reduction in all patients (n=72) was 69.20ml±93.00ml (p<0.000), for upper extremities (n=16) 26.20ml±45.99ml (p<0.039) and lower extremities (n=56) 81.40ml±99.50ml (p<0.000). In the intensive treatment phase (Phase 1) volume was reduced in twelve patients (n=12) by 112.50ml±118.78ml (p=0.005) and in the maintenance phase (Phase 2) in sixty patients (n=60) by 60.50ml±85.56ml (p<0.000). Phase 2 patients were further separated into stages. Volume in Stage I (n=9) patients was reduced by 75.00ml±98.14ml (p=0.038) and in Stage II (n=46) patients by 56.90ml±88.17ml (p<0.000). Numbers for Stage 0 and III patients were less than five and therefore excluded from analysis. Conclusion: This study showed that edema volume of the affected extremity was statistically significantly reduced after MLD treatment. Based on this result, MLD including Complex Physical Therapy should be recommended to become part of the health insurance plan.

Rhabdomyolysis secondary to an accident with marine stingray (Dasyatis family)

Whenever humans come in touch with the sea, they become vulnerable to risks, most frequently on account of invading a habitat that belongs to potentially harmful aquatic animals. World literature shows a growing number of incidents in recent years with marine stingrays, despite the fact that these animals only attack when harassed. This report describes an accident in which an amateur fisherman was injured by a marine stingray, probably of the Dasyatis family, on his left forearm. The puncture wound was highly painful and progressed to rhabdomyolysis. It is conjectured that lymphatic drainage, applied in an attempt to reduce edema and its complications, may have contributed to rebound increase in serum creatine kinase levels (CK) and, thus, has exacerbated the intensity of rhabdomyolysis. Therefore, as a measure of caution, lymphatic drainage should not enter current treatment protocols for similar cases, until new studies are performed in order to clarify this issue.
