RESUMEN
BACKGROUND: Rives-Stoppa retromuscular technique: A) polypropylene mesh fixed on the posterior rectus sheath; B) rectus abdominal muscle; C) anterior rectus sheath being sutured. The best technique for incisional hernioplasty has not been established yet. One of the difficulties to compare these techniques is heterogeneity in the profile of the patients evaluated. AIM: To analyze the results of three techniques for incisional hernioplasty after open bariatric surgery. METHOD: Patients who underwent incisional hernioplasty were divided into three groups: onlay technique, simple suture and retromuscular technique. Results and quality of life after repair using Carolina's Comfort Scale were evaluated through analysis of medical records, telephone contact and elective appointments. RESULTS: 363 surgical reports were analyzed and 263 were included: onlay technique (n=89), simple suture (n=100), retromuscular technique (n=74). The epidemiological profile of patients was similar between groups. The onlay technique showed higher seroma rates (28.89%) and used a surgical drain more frequently (55.56%). The simple suture technique required longer hospital stay (2.86 days). The quality of life score was worse for the retromuscular technique (8.43) in relation to the onlay technique (4.7) and the simple suture (2.34), especially because of complaints of chronic pain. There was no difference in short-term recurrence. CONCLUSION: The retromuscular technique showed a worse quality of life than the other techniques in a homogeneous group of patients. The three groups showed no difference in terms of short-term hernia recurrence.

RESUMO Racional: A melhor técnica de hernioplastia incisional ainda não foi definida. Uma das dificuldades na comparação é a heterogenicidade no perfil dos pacientes avaliados. Objetivo: Analisar os resultados de três técnicas de hernioplastia incisional após cirurgia bariátrica aberta. Método: Os pacientes que realizaram hernioplastias incisionais foram estudados e divididos em três grupos: técnica onlay, sutura simples e técnica retromuscular. Resultados e qualidade de vida após o reparo utilizando o Carolina's Comfort Scale foram avaliados através de análise de prontuários, contato telefônico e consultas eletivas. Resultados: Foram analisados 363 relatos cirúrgicos e 263 foram incluídos: técnica onlay (n=89), sutura simples (n=100), técnica retromuscular (n=74). O perfil epidemiológico dos pacientes foi similar entre os grupos. A técnica onlay apresentou maiores taxas de seroma (28,89%) e usou dreno com maior frequência (55,56%). A sutura simples obteve maior tempo de internação (2,86 dias). O escore de qualidade de vida foi pior na técnica retromuscular (8,43) em relação à onlay (4,7) e à sutura simples (2,34), especialmente devido às queixas de dor crônica. Não houve diferença quanto a recidiva em curto prazo. Conclusão: A técnica retromuscular apresentou pior qualidade de vida do que as demais técnicas em um grupo homogêneo de pacientes. Os três grupos não mostraram diferenças em termos de recidiva de hérnia em curto prazo.

BACKGROUND: Sepsis is an important public health issue and is associated with high treatment costs and high mortality rates. Glutamine supplementation has proven to be beneficial to the functions of the immune system, acting beneficially in the evolution of patients in severe catabolic states. AIM: To evaluate the effect of glutamine supplementation via intraperitoneal in rats, induced sepsis, considering the following organs: intestines, liver, kidneys and lungs. METHODS: Male Wistar rats subjected to sepsis by ligature and cecal puncture were divided into two groups: control C (n=6) and glutamine G (n=11), in which were administered dipeptiven 20% at a dose of 2 ml/kg/day (equivalent to 0.4g N(2)-L-alanyl-L-glutamine/kg) intraperitoneally 48 h prior to sepsis induction. After 48 h they were euthanized and intestine, liver, lung and kidney were removed for histological analysis. RESULTS: Intestinal epithelial desquamation of the control group was more intense compared to the glutamine group (p=0.008). In the kidneys, degenerative tubular epithelial changes were less severe in the animals that received glutamine (p=0.029). Regarding to the liver, glutamine group showed lower levels of cell swelling than the control group (p=0.034). In the lung there were no results with statistical significance. CONCLUSION: Prior intraperitoneal supplementation with glutamine in experimental animals is able to reduce the damage to the intestinal mucosa, to the kidneys and liver's histoarchitecture.

RESUMO Racional: A sepse é importante problema de saúde pública, sendo relacionada com altos custos de tratamento e elevadas taxas de mortalidade. A suplementação de glutamina tem provado ser benéfica às funções do sistema imune, atuando em estados catabólicos graves. Objetivo: Avaliar o efeito da suplementação de glutamina via intraperitoneal em ratos induzidos à sepse. Método: Foram utilizados ratos Wistar submetidos à sepse por ligadura e punção do ceco, separados em grupo controle C (n=6) e glutamina G (n=11), aos quais foram administrados dipeptiven a 20% com dose de 2 ml/kg/dia (equivalente a 0,4 g N(2)-L-alanil-L-glutamina/kg), via intraperitoneal, 48 h antes da indução da sepse. Após 48 h todos os animais foram submetidos à eutanásia e intestino, fígado, pulmão e rim foram retirados para análise histológica. Resultados: No intestino a descamação epitelial do grupo controle foi mais intensa em comparação ao da glutamina (p=0,008). Nos rins, houve menor degeneração do epitélio tubular nos animais que receberam glutamina (p=0,029). No fígado, o grupo glutamina apresentou índices menores de tumefação celular do que o grupo controle (p=0,034). No pulmão não houve resultados com significância estatística. Conclusão: A suplementação prévia de animais experimentais com glutamina via intraperitoneal é capaz de reduzir os danos causados à mucosa intestinal, histoarquitetura dos rins e do fígado.

BACKGROUND: Nonalcoholic fatty liver disease incidence is related to the presence of obesity and insulin resistance. A treatment of this disease in patients with morbid obesity is bariatric surgery and its diagnosis is extremely important due to the possible progression to cirrhosis or hepatocellular carcinoma. The development of clinical-laboratorial analysis tools to this disease and its complications is necessary as the gold standard for its diagnosis is an invasive procedure. The objective of the study is to evaluate the use of BARD score in the selection of patients who should undergo liver biopsy during bariatric surgery. METHODS: It was a retrospective analysis of patients with hepatic disease who were biopsied between 2012 and 2013. Their clinical and laboratory data were analyzed by BARD score. The results of those who presented score >2 were compared to the rest. RESULTS: Two hundred ninety-eight patients with hepatic disease were analyzed and among them 70.27 % had score >2. Of the 76 patients with score <1, 1 was diagnosed with liver fibrosis, determining a negative predictive value of 98.68 % for the test (p < 0.05). CONCLUSIONS: The BARD score is still not ideal for the diagnosis of nonalcoholic fatty liver disease, hepatitis, and fibrosis, but it was proved to be effective in the detection of absence of liver fibrosis in a bariatric population.
