ABSTRACT

RESUMEN La obesidad y el sobrepeso se definen como una acumulación anormal o excesiva de grasa que puede ser perjudicial para la salud. Es una enfermedad crónica de origen multifactorial, que como consecuencia ocasiona problemas higiénicos, discapacidad funcional y alteración de la calidad de vida. La dermolipectomía abdominal es una técnica quirúrgica que constituye la única opción para el tratamiento de pacientes con panículo adiposo prominente; de esa forma se logra disminuir las complicaciones y se reintegra socialmente al paciente que, a causa del enorme faldón abdominal, estuvo limitado por muchos años. Presentamos el caso de una paciente de 53 años con lipodistrofia abdominal grave, que llegaba a ambos tobillos con afectación cutánea, y discapacidad para realizar actividades diarias, resuelta con dermolipectomía abdominal y resección de 29 kg de tejido dermograso. Se realizará, además, una revisión bibliográfica del tema.


ABSTRACT Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. It is a chronic disease caused by multiple factors, which results in hygienic issues, functional disability and impaired quality of life. Abdominal dermolipectomy is the only surgical option for the treatment of patients with prominent panniculus morbidus, thus reducing complications and providing social reintegration for the patient who has been limited for many years due to the enormous abdominal panniculus. We report the case of a 53-year-old female patient with severe abdominal lipodystrophy with coverage of both ankles, skin involvement, and disability to perform daily activities, that was managed with abdominal dermolipectomy and resection of 29 kg of dermo-adipose tissue. Bibliographic research is also presented.

ABSTRACT

A obesidade é uma doença complexa que está associada inflamação crônica de baixo grau que contribui para o desenvolvimento de diversos distúrbios metabólicos como a resistência à insulina e estudos recentes sugerem a influência da microbiota intestinal no desenvolvimento e manutenção da doença. Diversos estudos apontam para o benefício da ingestão de frutas e vegetais na prevenção e tratamento de doenças crônicas. O suco de laranja contém diversos compostos bioativos com ações anti-inflamatórias, antioxidantes com efeitos na composição da microbiota intestinal. Deste modo, o objetivo principal deste estudo foi avaliar os efeitos da ingestão do suco de laranja Pera e Moro sobre a composição da microbiota intestinal e de parâmetros inflamatórios em voluntários com obesidade e resistência à insulina. Foi realizado um ensaio clínico crossover com suplementação de suco de laranja (400ml/dia) por 15 dias com um período de washout de 40 dias. As análises de sangue, fezes, urina, composição corporal, consumo alimentar foram realizadas antes e após cada intervenção. A comparação entre os tratamentos foi realizada utilizando equações de estimativas generalizadas e adotou-se um nível de significância de 5%. Em relação à microbiota intestinal, em ambos os tratamentos, os dois filos mais abundantes foram Firmicutes e Actinobateria. Dos gêneros analisados, observou-se maior abundância de Bifidobacterium após a suplementação com o suco de laranja Moro. O suco de laranja Pera promoveu uma diminuição da zonulina e o suco de laranja Moro contribuiu para redução de citocinas inflamatórias, diminuição da pressão arterial e aumento nos níveis de acetato nas fezes. Após a separação dos voluntários por grau de obesidade, observamos que o suco de laranja Moro contribuiu para o aumento na abundância de Akkermansia, Alistipes, Bacteroides e Catenibacterium em indivíduos com obesidade grau 3. Além disso, em ambos os sucos encontramos redução da razão Firmicutes/Bacteroidetes e aumento da excreção de metabólitos de flavonoides após os tratamentos. Diante destes resultados, conclui-se que o suco de laranja Pera apresentou ações positivas sobre a permeabilidade intestinal e o suco de laranja Moro promoveu efeitos mais expressivos na modulação da inflamação associada à obesidade e da microbiota intestinal


Obesity is a complex disease that is associated with low-grade chronic inflammation, and it contributes to the development of several metabolic disorders such as insulin resistance, and recent studies suggest the influence of the intestinal microbiota in the development and maintenance of the disease. Several studies have suggested the benefit of fruits and vegetables consumption in the prevention and treatment of chronic diseases. The orange juice contains some bioactive compounds with anti-inflammatory and antioxidant actions with effects in the composition of the gut microbiota. Thus, the main objective of this study was to evaluate the effects of Pera and Moro orange juice consumption on the composition of the gut microbiota and inflammatory parameters in volunteers with obesity and insulin resistance. A crossover clinical trial was carried out with orange juice supplementation (400ml/day) for 15 days with a washout period of 40 days. Blood, feces, urine, body composition, food consumption were analyzed before and after each intervention. Comparison between treatments was performed using generalized estimating equations and a significance level of 5% was adopted. In relation to gut microbiota, in both treatments, the two most abundant phyla were Firmicutes and Actinobateria. In the analysis of bacterial genera, a greater abundance of Bifidobacterium was observed after supplementation with Moro orange juice. The Pera orange juice reduced zonulin and Moro orange juice contributed to a reduction on inflammatory cytokines, a decrease in blood pressure and an increase in acetate levels in the stool. After separating the volunteers by degree of obesity, we observed that Moro orange juice contributed to the increase in the abundance of Akkermansia, Alistipes, Bacteroides and Catenibacterium in individuals with grade 3 obesity. Furthermore, in both juices we found a reduction in the Firmicutes/Bacteroidetes ratio and increased excretion of flavonoid metabolites after treatments. Therefore, we concluded that Pera orange juice had positive actions on intestinal permeability and Moro orange juice promoted more expressive effects on the modulation of inflammation associated with obesity and on the intestinal microbiota

ABSTRACT

ABSTRACT Objective: Identifying significant fibrosis is crucial to evaluate the prognosis and therapeutic interventions in patients with nonalcoholic fatty liver disease (NAFLD). We assessed the performance of acoustic radiation force impulse (ARFI) elastography, APRI, FIB-4, Forns, NFS and BARD scores in determining liver fibrosis in severe obesity. Subjects and methods: A prospective study included 108 patients undergoing bariatric surgery. Liver biopsy specimens were obtained intraoperatively and classified according to the NAFLD Activity Score. Patients were assessed with serological markers and shear wave velocity of the liver was measured with the Siemens S2000 ultrasound system preoperatively. Optimal cut-off values were determined using the area under the receiver operating characteristic curves (AUROC). Results: In the entire cohort prevalence of NAFLD was 80.6%, steatohepatitis 25.9% and significant fibrosis 19.4%. The best tests for predicting significant fibrosis were FIB-4 and Forns scores (both AUROC 0.78), followed by APRI (AUROC 0.74), NFS (AUROC 0.68), BARD (AUROC 0.64) and ARFI (AUROC 0.62). ARFI elastography was successful in 73% of the patients. Higher body mass index (BMI) correlated with invalid ARFI measurements. In patients with BMI < 42 kg/m2, ARFI showed 92.3% sensitivity and 82,6% specificity for the presence of significant fibrosis, with AUROC 0.86 and cut-off 1.32 m/s. Conclusions: FIB-4 and Forns scores were the most accurate for the prediction of significant fibrosis in bariatric patients. Applicability and accuracy of ARFI was limited in individuals with severe obesity. In patients with BMI < 42 kg/m2, ARFI elastography was capable for predicting significant fibrosis with relevant accuracy.

ABSTRACT

ABSTRACT Background: In the last decades, numerous studies have confirmed the importance of lactate - by-product to the nutrient signal of the intracellular redox state - to regulatory functions in energy metabolism. Aim: To evaluate changes in blood lactate in patients with severe obesity and its correlation with body composition and metabolic profile. Methods: Twenty-four people with severe obesity (BMI=40 kg/m2) were evaluated in a prospective case-control study before and six months after Roux-in-Y gastric bypass. The blood lactate, total cholesterol, and fractions, C-reactive protein and HOMA-IR were analyzed after 12 h fasting. Body mass composition was evaluated by bioelectrical impedance and respiratory quotient was measured by indirect calorimetry. Results: The initial lactate level was 2.5±1.1 mmol/l and returned to normal level (1.9±3.6 mmol/l, p=0.0018) after surgery. This reduction was positively correlated with a decrease in BMI (p=0.0001), % free fat mass (p=0,001), % fat mass (p=0.001) and HOMA-IR (p=0.01). There was normalization of lactatemia in 70% of patients. There was no correlation between lactatemia and C-reactive protein. Conclusions: There was a significant improvement of metabolic parameters, normalization of blood lactate, fat mass loss, although these individuals remained with a high BMI.


RESUMO Racional: Nas últimas décadas, inúmeros estudos confirmam a importância do lactato - subproduto ao sinal de nutrientes do estado redox intracelular - às funções reguladoras do metabolismo energético. Objetivo: Avaliar alterações no lactato sanguíneo em pacientes com obesidade grave e sua correlação com a composição corporal e o perfil metabólico. Métodos: Vinte e quatro pacientes com obesidade grave (IMC=40 kg/m2) foram avaliadas em um estudo prospectivo antes e após seis meses do bypass gástrico em Y-de-Roux. O lactato sanguíneo, colesterol total e frações, proteína C-reativa e HOMA-IR foram analisados após 12h de jejum. A composição corporal foi avaliada por bioimpedância elétrica e o quociente respiratório por calorimetria indireta. Resultados: O nível inicial de lactato foi de 2,5±1,1 mmol/l e retornou ao nível normal após a operação (1,9±3,6 mmol/l, p=0,0018). Essa redução foi correlacionada positivamente com a diminuição do IMC (p=0,0001), % de massa livre de gordura (p=0,001) e % de massa de gordura (p=0,001) e HOMA-IR (p=0,01). Houve normalização da lactatemia em 70% dos pacientes. Não houve correlação entre lactatemia e proteína C-reativa. Conclusões: Houve melhora significativa dos parâmetros metabólicos e normalização da lactatemia, perda de massa gorda, embora esses indivíduos permanecessem com IMC elevado.

ABSTRACT

ABSTRACT Introduction: obstructive Sleep Apnea Syndrome (OSAS) is a serious confition that compromises the quality of life and survival of patients. Its main risk fator in adults is obesity and the gold standard test for diagnosis is polysomnography (PSG), mainly through the apneia-hypopnea index (AHI). Objective: to analyze the sleep pattern of obese patients with indication for bariatric surgery, determining the main polisomnographic parameters compromised by obesity. Methods: This work is a cross-sectional study with analysis of polysomnography perfomed in patients with obesity in the peroperative period of bariatric surgery at a clinic in Vitória da Conquista/BA during 2017. The Epi Info 7 platform was used for analysis of the data. Results: 58 polysomnographic reports were analyzed, with 56,9% morbdly obese and 43,1% non-morbid. The prevalence of OSAS was 70,68% and de AHI ranged from zero to 84,6 with a mean of 19,47±22,89 e/h. morbidly obese, compared to "non-morbid", had a longer saturation time below 80% and 90% (0,4±0,93 vs. 0,12±0,45 e 4,87±7,38 vs. 1,36±2,87 respectively; p-value=0,02 in both), worse index respiratory disorders ((29,24±25,36 vs. 16,88±16,21; p-value=0,02), higher AHI (24,71±25,68 vs. 12,56±16,67; p-value=0,02), higher hypopnea index values (16,41±17,10 vs. 6,99±8,52; p-value=0,006) and lower minimum saturation (78,24±9,80 vs. 85,24±6,33; p-value=0,004). Conclusions: the high prevalence of OSAS found confirms its indication in the preoperative period of bariatric surgery. The main respiratory event involved in most individuals with OSAS was the hypopnea index.


RESUMO Introdução: a Síndrome da Apnéia e Hipopnéia Obstrutiva do Sono (SAHOS) é uma grave patologia que compromete a qualidade de vida e sobrevida dos portadores. Seu principal fator de risco em adultos é a obesidade e o exame padrão ouro para diagnóstico é a polissonografia (PSG), sobretudo através do índice de apneiahipopneia (IAH). Objetivo: analisar o padrão de sono dos pacientes obesos com indicação à cirurgia bariátrica, determinando os principais parâmetros polissonográficos comprometidos pela obesidade. Métodos: Este trabalho se trata de um estudo transversal com análise das polissonografias feitas em pacientes com obesidade no préoperatório de cirurgia bariátrica em uma clínica em Vitória da Conquista/BA durante o ano de 2017. Foi utilizada a plataforma Epi Info 7 para análise dos dados. Resultados: analisados 58 laudos polissonográficos, sendo 56,9% obesos mórbidos e 43,1% não mórbidos. A prevalência de SAHOS foi 70,68% e o IAH variou de zero a 84,6 com média de 19,47±22,89 e/h. Os obesos mórbidos, comparados aos "não mórbidos", tiveram maior tempo de saturação abaixo de 80% e 90% (0,4±0,93 vs. 0,12±0,45 e 4,87±7,38 vs. 1,36±2,87 respectivamente; p=0,02 em ambos), pior índice de distúrbios respiratórios (29,24±25,36 vs. 16,88±16,21; p=0,02), maior IAH (24,71±25,68 vs. 12,56±16,67; p=0,02), valores de índices de hipopneia superiores (16,41±17,10 vs. 6,99±8,52; p=0,006) e menor saturação mínima (78,24±9,80 vs. 85,24±6,33; p=0,004). Conclusões: a alta prevalência de SAHOS encontrada ratifica sua indicação no pré-operatório de cirurgia bariátrica. O principal evento respiratório envolvido na maioria dos indivíduos com SAHOS foi o índice de hipopneia.

ABSTRACT

ABSTRACT Objective: To examine epidemiologic, anthropometric and clinical variables associated with stress urinary incontinence in obese women, before and after bariatric surgery, and to identify predictive factors of stress urinary incontinence resolution. Methods: Prospective observational study with women enrolled in a bariatric surgery program between 2015 and 2016. Patients were assessed prior to and 6 months after bariatric surgery using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, the Patient Global Impression of Improvement and the Visual Analogue Scale. Patient assessment also included physical examination and bladder stress tests. Results: A total of 43 women completed the study. There was a 72.7% reduction in stress urinary incontinence (p=0.021). Predictive factors for preoperative diagnosis of stress urinary incontinence included age (p=0.024) and abdominal waist circumference (p=0.048). Urinary symptoms improved after weight loss, especially nocturia (p=0.001) and stress urinary incontinence (p=0.026). Menopause was the most significant predictive factor for persistence of stress urinary incontinence within six months of bariatric surgery (p=0.046). Self-reported outcomes and scores obtained in the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, the Patient Global Impression of Improvement and the Visual Analogue Scale were associated with significant improvement (p=0.012, p=0.025, and p=0.002 respectively). Conclusion: Older women with larger waist circumference have a higher risk of developing stress urinary incontinence prior to bariatric surgery. Menopausal women are highly prone to persistent stress urinary incontinence, even after weight loss. Weight loss achieved through bariatric surgery improved stress urinary incontinence symptoms and mitigated related impacts on quality of life in the vast majority of women.


RESUMO Objetivo: Examinar as variáveis epidemiológicas, antropométricas e clínicas associadas à incontinência urinária de esforço em mulheres obesas antes e após a cirurgia bariátrica e identificar fatores preditivos da resolução desse tipo de incontinência. Métodos: Estudo observacional prospectivo com mulheres de um programa de cirurgia bariátrica, realizado entre 2015 e 2016. As pacientes responderam ao International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, à Clinical Global Impression-Improvement e à Escala Visual Analógica, sendo submetidas ao exame físico e ao teste de incontinência antes e 6 meses após cirurgia bariátrica. Resultados: Completaram o estudo 43 mulheres. Houve redução de 72,7% na incontinência urinária de esforço (p=0,021). Fatores preditivos para o diagnóstico pré-operatório da incontinência urinária incluíram idade (p=0,024) e circunferência abdominal (p=0,048). Todos os sintomas urinários demonstraram melhora após perda de peso, notadamente noctúria (p=0,001) e incontinência urinária de esforço (p=0,026). A menopausa foi o fator mais crítico para predizer a persistência da incontinência urinária de esforço 6 meses após a cirurgia bariátrica (p=0,046). Os resultados relatados do International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form, da Patient Global Impression of Improvement e da Escala Visual Analógica tiveram melhora significativa (p=0,012, p=0,025, p=0,002, respectivamente). Conclusão: Mulheres idosas e com maior circunferência abdominal têm maior risco de desenvolver incontinência urinária de esforço antes da cirurgia. Mulheres na menopausa são fortemente propensas a persistir com a incontinência urinária de esforço, mesmo após a perda de peso. A perda de peso após a cirurgia bariátrica melhora os sintomas de incontinência urinária de esforço e seus impactos na qualidade de vida na maioria das mulheres.

ABSTRACT

Abstract Background: Opioid-free anesthesia decreases the incidence of opioid adverse events, but its optimal antinociceptive depth has not been clearly defined. Personalizing intraoperative opioid-free infusions with a nociception monitor may be the solution. Case report: We describe the feasibility and potential limitations of titrating opioid-free antinociception during major abdominal surgery using the Analgesia Nociception Index (Mdoloris, Lille, France) in an obese patient. After stabilizing the patient's nociception-antinociception balance intraoperatively we quickly reversed anesthesia and the patient did not require postoperative opioids. Conclusion: Personalizing opioid-free antinociception with a nociception monitor is feasible. It may optimize intraoperative antinociception and improve postoperative comfort.


Resumo Introdução A anestesia sem opioides diminui a incidência de eventos adversos associados aos opioides, mas a profundidade antinociceptiva ideal dessa abordagem não está claramente definida. Personalizar a infusão intraoperatória sem opioides com o uso de monitor de nocicepção pode ser a solução. Relato de caso Descrevemos a viabilidade e as eventuais limitações da titulação da antinocicepção sem opioides por meio do uso do Índice de Analgesia/Nocicepção (Mdoloris, Lille, França) durante cirurgia abdominal de grande porte em paciente com obesidade. Depois de estabilizar o equilíbrio nocicepção-antinocicepção da paciente no intraoperatório, revertemos rapidamente a anestesia e a paciente não precisou de opioides no pós-operatório. Conclusão A personalização da antinocicepção sem opioides por meio do emprego de monitor de nocicepção é factível. A abordagem pode otimizar a antinocicepção intraoperatória e melhorar o conforto pós-operatório.

ABSTRACT

Resumen: En los últimos años, la obesidad severa en adolescentes ha aumentado a nivel mundial y Chile no es la excepción a este fenómeno. Es conocido que esta condición aumenta exponencialmente los riesgos para la salud y se asocia a mortalidad prematura. Desde el año 2008, diversas guías de tratamiento de obesidad pediátrica han incluido a la cirugía bariátrica como una estrategia de tratamiento para adolescentes obesos severos seleccionados. Estos procedimientos han mostrado ser seguros y eficaces en adultos. Un cuerpo emergente de evidencia demuestra que, en centros especializados, en el corto y mediano plazo se obtendrían resultados similares en adolescentes. Sin embargo, en este grupo de pacientes, la cirugía bariátrica tiene implícitos otros riesgos inherentes a la etapa de desarrollo en que se encuentran, y los resultados y complicaciones especialmente de largo plazo en gran medida son aún desconocidos. Por lo anterior y para el logro de los resultados esperados, es muy importante que la selección de pacientes, la cirugía y el seguimiento, sean realizados por equipos multidisciplinarios calificados, en centros hospitalarios que cuenten con la infraestructura adecuada, siendo imprescin dible la adherencia de por vida al seguimiento médico y nutricional. El objetivo de este documento es presentar la postura de la Rama de Nutrición de la Sociedad Chilena de Pediatría (SOCHIPE) frente a las diversas aristas a considerar para la adecuada indicación de estos procedimientos en adolescentes obesos severos.


Abstract: In recent years, severe obesity in adolescents has been rising worldwide, and Chile is no exception to this phenomenon. This condition exponentially increases health risks and it is associated with prema ture mortality. Since 2008, several guidelines on pediatric obesity treatment have included bariatric surgery as a treatment strategy for certain severely obese adolescents. These procedures have proven to be safe and efficient in adults. Recent evidence shows that, when done in specialized centers, the re sults would be similar in adolescents in the short and medium term. Nonetheless, in this group of pa tients, bariatric surgery has risks related to their stage of development, and data on long-term results and complications are still lacking. Therefore, to achieve the expected results, the patient selection, surgery, and follow-up must be carried out by qualified multidisciplinary teams, in hospitals centers that have the appropriate infrastructure, It is essential for the patients a life-long adherence to medi cal and nutritional monitoring. The objective of this document is to present the position statement of the Nutrition Branch of the Chilean Society of Pediatrics on the different issues to be considered for the adequate indication of these procedures in severely obese adolescents.

ABSTRACT

Introdução: Atualmente com o aumento das gastroplastias redutoras (cirurgia bariátrica) e grande perda ponderal, há também um aumento na procura destes pacientes pela cirurgia plástica. Uma das características destes pacientes é o excesso de tecido dermogorduroso que causa deformidades, principalmente nos membros inferiores, acometendo a região trocantérica. Objetivo: Relatar um caso de dermolipectomia trocantérica em paciente pós-cirurgia bariátrica, onde a lipoaspiração por si só não resolveria a correção da deformidade. Relato de caso: IPMS, sexo feminino, 55 anos, histórico de gastroplastia redutora (cirurgia bariátrica) com grande perda ponderal. Relata desconforto importante com a lipodistrofia e extensa flacidez em região trocantérica bilateral. Após avaliação pela equipe, foi optado por realizar dermolipectomia trocantérica bilateral, em janeiro de 2019, no Serviço de Cirurgia Plástica Osvaldo Saldanha. Discussão: Nos casos de lipodistrofia trocantérica com deformidades graves, a cicatriz da dermolipectomia em relação à deformidade é favorável quanto a escolha desta técnica, pois a lipoaspiração poderá agravar ainda mais a deformidade, sendo mandatório utilizar a técnica de dermolipectomia trocantérica para corrigila. Quanto à lipodistrofia com deformidade moderada há dúvida entre a relação do benefício e a deformidade resultante, sendo aplicada a técnica de acordo com a necessidade do paciente e, por fim, nos casos de lipodistrofia com deformidade leve, opta-se pela lipoaspiração devido à correção ser realizada sem grandes cicatrizes aparentes. Conclusão: Portanto, a lipoaspiração tem benefício nos casos de adiposidade localizada, limitando as indicações da técnica de dermolipectomia, em especial na região trocantérica, sem invalidá-la para casos selecionados, como o descrito neste relato de caso.


Introduction: Currently, with the increase in reducing gastroplasty (bariatric surgery) and the great weight loss, there is also an increase in the demand of these patients for plastic surgery. One of the characteristics of these patients is the excess of dermal adipose tissue that causes deformities, especially in the lower limbs, affecting the trochanteric region. Objective: To report a case of trochanteric dermolipectomy in a patient after bariatric surgery, where liposuction alone would not solve the correction of the deformity. Case report: IPMS, female, 55 years old, history of reducing gastroplasty (bariatric surgery) with great weight loss. She reports significant discomfort with lipodystrophy and extensive flacidity in the bilateral trochanteric region. After the team's evaluation, it was decided to perform bilateral trochanteric dermolipectomy, in January 2019, at the Plastic Surgery Service Osvaldo Saldanha Discussion: In cases of trochanteric lipodystrophy with severe deformities, the scar of dermolipectomy in relation to the deformity is favorable in terms of the choice of this technique, since liposuction may further aggravate the deformity, and it is mandatory to use the trochanteric dermolipectomy technique to correct it. Conclusion: Therefore, liposuction is beneficial in cases of localized adiposity, limiting the indications for the dermolipectomy technique, especially in the trochanteric region, without invalidating it for selected cases, as described in this case report.

ABSTRACT

Abstract Morbid obesity is associated with various pathophysiological changes which affect the outcome of anaesthesia and surgery. So it's challenging to give anaesthesia to such patients. We present a 59-year-old adult morbidly obese, hypertensive, diabetic female with hypothyroidism operated for proximal humerus fracture and now presented with non-union of fracture, requiring percutaneous injection of bone marrow aspirate from the iliac crest to the site of non-union. The patient was extremely anxious and refused to undergo the procedure under local anaesthesia or sedation and demanded anaesthesia. Given her comorbidities general anaesthesia (GA) was avoided and the procedure was accomplished using Ultrasound (USG) guided Transversus abdominis plane (TAP) block and Lateral Femoral Cutaneous Nerve (LFCN) block for the bone marrow aspirate from the iliac crest and Intercostobrachial nerve block (T2) was given to prevent pain while injecting the aspirate into the non-union site. Dexmedetomidine and ketamine were given for deep level sedation and analgesia. TAP block and LFCN block is generally used for post-op analgesia but can be also used for surgical anaesthesia instead of General anaesthesia in specific scenarios. Its perioperative application and its potential use instead of GA have been discussed.


Resumo A obesidade mórbida se associa a várias alterações fisiopatológicas que afetam o desfecho da anestesia e cirurgia. É, portanto, um desafio anestesiar tais pacientes. Apresentamos uma mulher adulta de 59 anos, obesa mórbida, hipertensa, diabética, com hipotiroidismo, submetida a cirurgia devido a fratura proximal do úmero e que compareceu ao serviço com fratura não consolidada, e com indicação de injeção percutânea de aspirado de medula óssea da crista ilíaca na fratura não consolidada. A paciente estava extremamente ansiosa e recusou o procedimento sob anestesia local ou sedação e exigiu anestesia. Em função de suas comorbidades, Anestesia Geral (AG) foi evitada e o procedimento foi realizado usando bloqueio do Plano Transverso Abdominal (PTA) guiado por Ultrassonografia (USG) e bloqueio do Nervo Cutâneo Femoral Lateral (NCFL) para aspiração de medula óssea da crista ilíaca. O bloqueio do nervo Intercostobraqueal (T2) foi realizado para evitar dor durante a injeção do aspirado. Dexmedetomidina e ketamina foram dadas para sedação profunda e analgesia. O Bloqueio PTA e bloqueio NCFL geralmente são usados para analgesia pós-operatória, mas também podem ser usados para anestesia cirúrgica substituindo a anestesia geral em condições clínicas específicas. O emprego desses bloqueios no perioperatório e seu uso potencial no lugar de AG têm sido discutidos.

ABSTRACT

Abstract: Introduction: Anterior dislocation is a rare complication of total hip arthroplasty (THA). There exist only three cases in the literature. None of them report disassembly of the prosthesis components. We present a morbidly obese woman who suffered an irreducible obturator dislocation of an infected total hip arthroplasty (THA), due to uncontrolled adduction during an early debridement surgery. Following unsuccessful closed reduction attempts, a Vancouver B2 periprosthetic fracture and disassembly of the prosthetic components were observed. Two-stage revision THA was necessary to resolve the infection and restore hip functionality. In obturator dislocation, the femoral head prosthetic can be trapped in the obturator foramen, and this may disassemble the prosthesis components during reduction maneuvers; there's also risk of periprosthetic fracture. This mandate an open reduction of the joint. Patient obesity could be a determining factor for this rare type of hip arthroplasty dislocation. Obturator dislocation is an extremely rare complication of the total hip arthroplasty, whose reductions should be handled with caution given the risks of periprosthetic fractures. In most cases, an open reduction of the joint is required. Clinical importance: Our work is likely to be of great interest because it offers tips for the management of this rare complication based on our experience.


Resumen: Introducción: La luxación anterior es una complicación poco frecuente de la artroplastia total de cadera (ATC). Sólo existen tres casos en la literatura. Ninguno de ellos informa del desmontaje de los componentes de la prótesis. Presentamos el caso una mujer obesa que sufrió una luxación irreducible de una artroplastia total de cadera (THA), la cual estaba infectada, debido a la aducción no controlada durante una cirugía de desbridamiento temprano. Después de los intentos fallidos de reducción cerrada, se presentó una fractura periprotésica clasificada como Vancouver B2 y el desmontaje de los componentes protésicos. Ameritó cirugía de revisión en dos etapas, lo cual se realizó para resolver la infección y restaurar la funcionalidad de la cadera. En la luxación obturatriz, la cabeza femoral puede quedar atrapada en el agujero obturador y, como consecuencia, favorecer la disociación de los componentes protésicos al intentar la reducción, asimismo puede favorecer un brazo de palanca que produzca una fractura periprotésica. La obesidad puede ser un factor determinante para la producción de esta rara complicación. Por todo lo anterior, se recomienda considerar de entrada la reducción abierta. La luxación obturatriz es una complicación rara en la artroplastia total de cadera; su tratamiento puede ser difícil y asociarse a fracturas. La relevancia de este caso es que permite mostrar algunas estrategias de manejo para prevenir complicaciones catastróficas.

ABSTRACT

Resumen En las últimas décadas, la prevalencia de la obesidad ha aumentado a escala mundial y ha provocado complicaciones metabólicas tales como diabetes de tipo 2, esteatosis, problemas cardiovasculares, entre otras. Su desarrollo puede estar influenciado por factores genéticos y ambientales, incluyendo la microbiota intestinal. En México, el 33.3% de la población adulta padece de este problema. La obesidad involucra un incremento excesivo del tejido adiposo que produce su disfunción. Se ha demostrado que la remodelación del tejido adiposo, dada por angiogénesis, hipoxia e inflamación, otorga susceptibilidad a desarrollar obesidad y conlleva a modificaciones metabólicas. La cirugía bariátrica ha sido el procedimiento más utilizado y más exitoso para tratar la obesidad mórbida en cuanto a la pérdida de peso corporal a largo plazo y a la remisión de comorbilidades como la diabetes tipo 2. En este artículo se revisan los aspectos moleculares por medio de los cuales la cirugía bariátrica provoca cambios metabólicos que se reflejan en la pérdida de peso y las mejoras metabólicas. Por lo tanto, se resumen aspectos genéticos, de microbioma y moleculares (remodelación del tejido adiposo) que influyen en el desarrollo de la obesidad. También se explican los aspectos moleculares a través de los cuales se puede modular la pérdida de peso y la mejoría de comorbilidades metabólicas.


Abstract Obesity prevalence has increased in the last decades worldwide leading to metabolic complications, such as type 2 diabetes, steatosis, cardiovascular disease, among others; its development is influenced by genetic factors and environmental factors, such as intestinal microbiome. In Mexico, 33.3% of the adults present this disease. Obesity is defined as an excessive adipose tissue accumulation, provoking its dysfunction. Adipose tissue remodeling, which involves angiogenesis, hypoxia and inflammation, is implicated in the developing of obesity and metabolic modifications. Bariatric surgery is the most used and successful intervention to control morbid obesity, leading a maintained loss of weight and remission of some of its comorbidities as type 2 diabetes. Here, we review some of the molecular aspects of the metabolic changes provoked by bariatric surgery and its impact in weight loss and comorbidities remission. In summary, this article reviews the genetic aspects, microbiome and molecular facts (adipose tissue remodeling) that are involved in obesity development. In addition, some of the molecular aspects about bariatric surgery are described and the mechanisms that are regulated to control obesity and its comorbidities.

ABSTRACT

OBJECTIVES: The number of bariatric procedures has significantly increased in Brazil, especially in the public Unified Health System. The present study describes health outcomes and medication use in obese patients treated in a major hospital that performs publicly funded surgery in Brazil. METHODS: A retrospective, single center study was conducted to collect real-world evidence of health outcomes and medication use in 247 obese patients (female, 82.2%) who underwent open Roux-en-Y gastric bypass. Changes in weight and body mass index (BMI), presence of apnea, hypertension, and type 2 diabetes (T2D), and medication use (hypertension, diabetes, and dyslipidemia) were assessed preoperatively and up to 24 months postoperatively. The mean cost of medications was calculated for the 12-month preoperative and 24-month postoperative periods. RESULTS: During the surgery, the mean age of patients was 43.42 years (standard deviation [SD], 10.9 years), and mean BMI was 46.7 kg/m2 (SD, 6.7 kg/m2). At 24 months, significant declines were noted in weight (mean, -37.6 kg), BMI (mean, -14.3 kg/m2); presence of T2D, hypertension, and apnea (-29.6%, -50.6%, and -20.9%, respectively); and number of patients using medications (-66.67% for diabetes, -41.86% for hypertension, and -55.26% for dyslipidemia). The mean cost of medications (total costs for all medications) decreased by >50% in 12-24 postoperative months compared to that in 12 preoperative months. CONCLUSION: Roux-en-Y gastric bypass successfully reduced weight, BMI, and comorbidities and medication use and cost at 24 months in Brazilian patients treated in the public Unified Health System.

ABSTRACT

ABSTRACT Background: Strongly associated with obesity, non-alcoholic fatty liver disease is considered the hepatic manifestation of the metabolic syndrome. It presents as simple steatosis and steatohepatitis, which can progress to cirrhosis and its complications. Among the therapeutic alternatives is bariatric surgery. Aim: To compare the effect of the two most frequent bariatric procedures (sleeve and bypass) on liver disease regarding to epidemiological, demographic, clinical and laboratory parameters. Methods: The results of intraoperative and 12 months after surgery liver biopsies were used. The NAFLD activity score (NAS) was used to assess and compare the stages of liver disease. Results: Sixteen (66.7%) patients underwent Bypass procedure and eight (33.3%) Sleeve. It was observed that the variation in the NAFLD activity score was significantly greater in the Bypass group than in Sleeve (p=0.028) and there was a trend regarding the variation in fibrosis (p=0.054). Conclusion: Both surgical techniques were effective in improving the hepatic histology of most operated patients. When comparing sleeve and bypass groups, bypass showed better results, according to the NAS score.


RESUMO Racional: Fortemente associada à obesidade, a doença hepática gordura não alcoólica é considerada a manifestação hepática da síndrome metabólica. Ela apresenta-se como esteatose simples e esteato-hepatite, podendo evoluir para cirrose e suas complicações. Entre as alternativas terapêuticas está a cirurgia bariátrica. Objetivo: Comparar o efeito sobre a doença hepática dos dois procedimentos bariátricos mais frequentes - sleeve e bypass - e comparar dados epidemiológicos, demográficos, parâmetros clínicos e laboratoriais. Métodos: Utilizou-se o resultado das biópsias hepáticas realizadas no intra-operatório e 12 meses após a operação. O NAFLD activity score foi utilizado para avaliar e comparar os estágios da doença hepática. Resultados: Dezesseis (66,7%) pacientes foram submetidos ao bypass e oito (33,3%) ao sleeve. Observou-se melhora significativa no IMC e glicemia nas duas técnicas cirúrgicas enquanto que os níveis de fosfatase alcalina, ferritina, Gama-GT e TGP reduziram com significância apenas no grupo bypass. A redução no NAFLD activity score foi significativamente maior no grupo bypass que no sleeve (p=0,040). Conclusão: Ambas as técnicas foram eficazes em promover a melhora da histologia hepática da maior parte dos pacientes operados. Quando comparadas o bypass apresentou melhores resultados.

ABSTRACT

ABSTRACT Prioritizing surgical procedures aims at facilitating patient's access according to the clinical needs, maximizing access equity, and minimizing the damage from delayed access. Previous categorization of elective bariatric surgery have been adapted to define an objective prioritizing system that reflects those principles for bariatric and metabolic operations. Given the factors that contribute to the morbidity and mortality of obese and type 2 diabetes patients, surgical prioritization should be based on clinical risk stratification. For patients with type 2 diabetes, we suggest that the operation may be prioritized for those with a higher risk of morbidity and mortality in a relatively short term. Likewise, it is necessary to guide the surgical team regarding the necessary care both in the pre, per and postoperative periods of bariatric and metabolic surgery. These recommendations aim to reduce the risk of in-hospital contamination of the surgical team among health professionals and between health professionals and patients. In summary, these recommendations have been shaped after a thorough analysis of the available literature and are extremely important to mitigate the harm related to the clinical complications of obesity and its comorbidities while keeping healthcare providers' and patients' safety.


RESUMO A priorização de qualquer operação eletiva visa facilitar o acesso do paciente de acordo com as necessidades clínicas, maximizando a equidade de acesso e minimizando os danos causados pelo atraso. As categorias de operações eletivas foram adaptadas para definir sistema de priorização objetiva que reflete esses princípios para operações bariátricas e metabólicas. Em razão dos fatores que contribuem para a morbidade e mortalidade da obesidade e do diabetes tipo 2, a priorização cirúrgica deve ser baseada na estratificação de risco clínico. Para pacientes com diabetes tipo 2, sugerimos que a operação possa ser priorizada para aqueles com maior risco de morbidade e mortalidade, em prazo relativamente curto. Da mesma forma, é necessário orientar a equipe cirúrgica quanto aos cuidados necessários tanto no pré, per e pós-operatório da cirurgia bariátrica e metabólica. As recomendações visam reduzir o risco de contágio hospitalar da equipe cirúrgica tanto entre profissionais de saúde quanto entre profissionais de saúde e pacientes. Em resumo, estas recomendações foram moldadas após análise minuciosa da literatura disponível e são extremamente importantes para mitigar os danos das complicações clínicas, sensíveis a doença obesidade e comorbidades, mantendo a segurança dos profissionais de saúde e dos pacientes.

ABSTRACT

El bypass gástrico en Y-de-Roux (RYGB) trata eficazmente la obesidad y a la vez la enfermedad por reflujo gastroesofágico (ERGE). Desafortunadamente, algunos pacientes que finalmente se presentan para cirugía bariátrica han sido previamente sometidos a una funduplicatura de Nissen por ERGE. La conversión a RYGB después de esta funduplicatura ha demostrado ser segura y eficaz, pero con una mayor morbilidad, tiempo operatorio más prolongado y mayor estancia hospitalaria. Se presenta una paciente de 50 años, con IMC 40,4 kg/m², evaluada para cirugía bariátrica. Había sido sometida a funduplicatura de Nissen laparoscópica siete años atrás. Informamos un caso de eliminación laparoscópica de funduplicatura de Nissen y conversión a RYGB. La funduplicatura previa no es una contraindicación para LRYGB. Estos procedimientos deben ser llevados a cabo por cirujanos experimentados, y el abordaje laparoscópico debe ser el método de elección.


Roux-en-Y gastric bypass (RYGB) effectively treats both obesity and gastroesophageal reflux disease (GERD). Unfortunately, some patients finally present for bariatric surgery have previously undergone Nissen fundoplication due to GERD. Conversion to EYGB after Nissen fundoplication is safe and effective, but is associated with greater morbidity and longer operative time and hospital stay. A 50-year-old female patient with a body mass index (BMI) of 40.4 kg/m² was evaluated for bariatric surgery. She had a history laparoscopic Nissen fundoplication seven years before. We report a case of laparoscopic take-down of Nissen fundoplication and conversion to RYGB. A previous fundoplication is not a contraindication for laparoscopic RYGB. These procedures should be performed by well-trained surgeons and laparoscopic approach should be the method of choice.

ABSTRACT

Introdução: Redução ponderal conseguida após cirurgia bariátrica pode resultar em deformidades de diversos segmentos corporais. Necessidade da redução das sobras de pele e da remodelação do corpo faz com que a cirurgia do contorno corporal seja procurada por pacientes para melhorar a qualidade de vida. Objetivo do estudo é apresentar a rotina de cirurgia plástica pós-bariátrica do Hospital Daher. Métodos: Estudo observacional longitudinal retrospectivo. Como rotina, dividimos os procedimentos em duas etapas realizadas em atos operatórios distintos: princípio dos dois andares. Descrevemos a rotina dos cuidados pré, intra e pós-operatório, bem como detalhes das técnicas cirúrgicas. Imagens fotográficas foram analisadas por um avaliador externo. Resultados: Estudo composto 13 pacientes ex-obesos, média de idade de 44 anos. Seis pacientes foram submetidos a cirurgia do andar inferior e superior e outros 6 apenas do andar inferior. Tempo médio da cirurgia do andar inferior foi de 4 horas e 54 minutos e do andar superior foi de 4 horas e 5 minutos. 92,30% dos pacientes mostraram-se satisfeitos com o resultado. Avaliação externa revelou uma taxa de 92,30% dos casos classificados como bons ou ótimos. Conclusão: Abdominoplastia circunferencial traz grandes benefícios e as cirurgias complementares são primordiais para um resultado satisfatório. Redução do tempo cirúrgico exige grande sincronização da equipe cirúrgica, permitindo realizar procedimentos combinados por times cirúrgicos trabalhando em compartimentos corporais diferentes, em tempo simultâneo. Resultados satisfatórios obtidos e baixos índices de complicação possibilitam aplicabilidade da nossa rotina em pacientes pós-bariátricos.


Introduction: Weight reduction achieved after bariatric surgery can result in deformities of various parts of the body. The need for reduction of leftover skin and body remodeling makes patients seek body contouring surgery to improve their quality of life. The aim of the study was to present a protocol for post-bariatric plastic surgery at Daher Hospital. Methods: This was a retrospective longitudinal observational study. As routine protocol, we divided the procedures into two steps, performed in different surgical stages, which we termed the two-level principle. Herein we describe the routine of pre, intra, and postoperative care, as well as details of the surgical techniques. Photographic images were analyzed by an external evaluator. Results: The study included 13 ex-obese patients, with a mean age of 44 years. Of them, 6 patients underwent lowerand upper-level surgeries and another 6 underwent lower-level surgeries. The mean surgical time for the lower level was 4 hours and 54 minutes and that for the upper level was 4 hours and 5 minutes. A total of 92.30% of the patients were satisfied with the results. An external evaluator classified 92.30% of the cases as good or great. Conclusion: Circumferential abdominoplasty has immense benefits and complementary surgeries are vital for a satisfactory result. Reduction of the surgical time requires great synchronization of the surgical team, which allows procedures to be performed simultaneously by multiple surgical teams working in different body parts. Satisfactory results and low complication rates allow the applicability of our routine in post-bariatric patients.

ABSTRACT

Introducción: Las personas obesas son consideradas pacientes de riesgo para la intubación, de modo que el tiempo entre la pérdida de la consciencia y la intubación de la tráquea debe ser el más corto posible. Objetivo: Evaluar las condiciones de intubación traqueal en obesos tratados con cirugía bariátrica laparoscópica al usar rocuronio comparado con succinilcolina. Métodos: Estudio cuasiexperimental, comparativo y transversal realizado en el Hospital Universitario Gral. Calixto García, desde enero de 2016 hasta diciembre de 2017, en 64 pacientes obesos programados electivamente para cirugía bariátrica laparoscópica, divididos en dos grupos: Grupo S: succinilcolina 1 mg/Kg de peso real y Grupo R: rocuronio 0,6 mg/Kg de peso ideal. Las variables analizadas fueron: edad, sexo, índice de masa corporal, tiempo de latencia, índice de bloqueo máximo, condiciones de intubación y efectos secundarios. Resultados: El rango de edad que predominó en ambos grupos fue 40 a 59 años, y en su mayoría mujeres. El mayor número de pacientes presentaron una obesidad grado III y estado físico ASA II. Los tiempos medios de latencia e índices de bloqueo máximo fueron significativamente menores en los pacientes en que se usó succinilcolina respecto a los que usaron rocuronio. Las condiciones de intubación a los 40 seg en los dos grupos, según la escala de Cooper, fueron excelentes y buenas, sin diferencias significativas. Conclusiones: El rocuronio es una alternativa segura para conseguir condiciones óptimas de intubación en pacientes obesos tratados con cirugía bariátrica laparoscópica, al compararlo con la succinilcolina(AU).


Introduction: Obese people are considered patients at risk for intubation, so that the time between loss of consciousness and intubation of the trachea should be as short as possible. Objective: To evaluate the conditions of tracheal intubation in obese patients treated with laparoscopic bariatric surgery when using rocuronium compared to succinylcholine. Methods: Quasi-experimental, comparative and cross-sectional study carried out in General Calixto García University Hospital, from January 2016 to December 2017, in 64 obese patients electively scheduled for laparoscopic bariatric surgery, divided into two groups: Group S: succinylcholine 1 mg/Kg of real weight and Group R: rocuronium 0.6 mg/Kg of ideal weight. The variables analyzed were: age, sex, body mass index, latency time, maximum blocking index, intubation conditions and side effects. Results: The age range that predominated in both groups was 40 to 59 years, and mostly women. The highest number of patients presented a grade 3 obesity and physical state ASA II. Mean latency times and maximal blockade rates were significantly lower in patients in whom succinylcholine was used than in those who used rocuronium. The conditions of intubation at 40 seconds in the two groups, according to the Cooper scale, were excellent and good, without significant differences. Conclusions: Rocuronium is a safe alternative to achieve optimal intubation conditions in obese patients treated with laparoscopic bariatric surgery, when compared to succinylcholine(AU)

ABSTRACT

ABSTRACT Purpose: Obesity is associated with eye diseases, but the underlying structural changes and pathogenic mechanisms have not been examined in detail. Here, we assessed the effects of morbid obesity on the morphometric indices of eye disease. Methods: Morbidly obese volunteers (n=101, body mass index [BMI] ³40) and healthy individuals (n=95, BMI: 18.50-24.99) were examined by Goldman applanation tonometry, pachymetry, and spectral domain optical coherence tomography. Intraocular pressure, anterior chamber depth, axial length, central corneal thickness, retinal nerve fiber layer thickness, central foveal thickness, and choroidal thickness were compared between groups. Results: Uncorrected intraocular pressure was significantly greater in the morbidly obese group than in the healthy control group (15.5 ± 2.5 vs. 14.5 ± 2.6 mmHg, p=0.009), whereas axial length, anterior chamber depth, and central corneal thickness did not differ between the groups. The mean retinal nerve fiber layer thickness at the temporal quadrant was reduced in the morbidly obese group (72.7 ± 13.6 vs. 85.05 ± 52.6 mm, p=0.024). Similarly, the mean retinal thicknesses at nasal and temporal 1500-mm locations were lower in the morbidly obese group (346.6 ± 18.2 vs. 353.7 ± 18.8 mm, p=0.008; 323.1 ± 20.3 vs. 330.0 ± 18.9 mm, p=0.001). The mean choroidal thickness was also reduced in almost all measurement locations (fovea, temporal 500 and 1000 mm, and nasal 500, 1000, and 1500 mm) of the obese group (p<0.05). Weight and BMI were negatively correlated with subfoveal choroidal thickness (r=-0.186, p=0.009; r=-0.173, p=0.015). Conclusion: Morbid obesity is associated with elevated uncorrected intraocular pressure and signs of neuropathy and retinopathy. Obesity may thus increase the risks of glaucoma and glaucomatous optic neuropathy.


RESUMO Objetivo: A obesidade está associada a doenças oulares, mas as mudanças estruturais subjacentes e os mecanismos patogênicos não foram examinados detalhadamente. Aqui avaliamos os efeitos da obesidade mórbida nos índices morfométricos da doença ocular. Métodos: Voluntários obesos mórbidos (n=101, índice de massa corporal ³40) e indivíduos saudáveis (n=95, índice de massa corporal 18,50 a 24,99) foram examinados por tonometria de aplanação de Goldman, paquimetria e tomografia de coerência óptica de domício espectral. A pressão intraocular, profundidade da câmara anterior, comprimento axial, espessura central da córnea, espessura da camada de fibras nervosas da retina, espessura foveal central e espessura da coroide foram comparadas entre os grupos. Resultados: A pressão intraocular não corrigida foi significativamente maior no grupo com obesidade mórbida do que no grupo controle saudável (15,5 ± 2,5 vs. 14,5 ± 2,6 mmHg, p=0,009), enquanto que o comprimento axial, profundidade da câmara anterior e espessura central da córnea não diferiram entre os grupos. A espessura média da camada de fibras nervosas da retina no quadrante temporal foi reduzida no grupo com obesidade mórbida (72,7 ± 13,6 vs. 85,05 ± 52,6 mm, p=0,024). Da mesma forma, a média das espesuras da retinianas nas localizações nasal e temporal de 1500 m foi menor no grupo com obesidade mórbida (346,6 ± 18,2 mm vs. 353,7 ± 18,8 mm, p=0,008; 323,1 ± 20,3 mm vs. 330,0 ± 18,9 mm, p=0,001). A espessura média da coroide também foi reduzida em quase todos os locais de mensuração (fóvea, temporal 500 e 1000 mm, nasal 500, 1000 e 1500 mm) do grupo obeso (p<0,05). Peso e índice de massa corporal foram negativamente correlacionados com a espessura da coroide subfoveal (r=-0,186, p=0,009; r=-0,173, p=0,015). Conclusão: A obesidade mórbida está associada à elevada pressão intraocular não corrigida e a sinais de neuropatia e retinopatia. A obesidade pode, assim, aumentar os riscos de glaucoma e neuropatia óptica glaucomatosa.
