RESUMO
BACKGROUND: The influence of body mass index on perioperative complications of hiatal hernia surgery is controversial in the surgical literature. AIMS: The aim of this study was to evaluate the influence of body mass index on perioperative complications and associated risk factors for its occurrence. METHODS: Two groups were compared on the basis of body mass index: group A with body mass index <32 kg/m2 and group B with body mass index ³32 kg/m2. A multivariate analysis was carried out to identify independent predictors for complications. Complications were classified based on the Clavien-Dindo score. RESULTS: A total of 49 patients were included in this study, with 30 in group A and 19 in group B. The groups were compared based on factors, such as age, Charlson Comorbidity Index, surgical techniques used, type and location of hiatal hernia, and length of stay. Findings showed that 70% of patients had complex hiatal hernia. In addition, 14 complications also occurred: 7 pleuropulmonary and 7 requiring reoperation. From the seven reoperated, there were three recurrences, two gastrointestinal fistulas, one diaphragmatic hernia, and one incisional hernia. Complications were similar in both the groups, with type IV hiatal hernia being the only independent predictor. CONCLUSIONS: Body mass index does not affect perioperative complications in anti-reflux surgery and type IV hiatal hernia is an independent predictor of its occurrence.

RESUMO RACIONAL: O impacto do índice de massa corpórea nos resultados da cirurgia de hérnia de hiato é controverso na literatura. OBJETIVOS: avaliar o impacto do índice de massa corpórea nas complicações perioperatórias em pacientes submetidos a cirurgia de hérnia hiatal, e seus possíveis preditores. MÉTODOS: análise retrospectiva 49 pacientes submetidos a tratamento cirúrgico de hérnias hiatais complexas por videolaparoscopia, divididos em dois grupos pelo índice de massa corpórea (grupo A<32kg/m2 - 30 pacientes e grupo B ³32 kg/m2 — 19 pacientes) e comparados quanto suas características e complicações. A análise multivariada foi aplicada para avaliar as variáveis preditoras independentes de complicações. As complicações foram classificadas conforme Clavien Dindo. RESULTADOS: Os grupos foram similares conforme a idade, índice de comorbidade de Charlson, técnica operatória empregada, tipo de hérnia de hiato, área do hiato esofageano, e tempo de internação pós-operatória. Setenta por cento dos pacientes possuíam hérnias de hiato complexas (gigantes ou recidivadas). Catorze complicações foram observadas: 7 pleuro pulmonares e 7 necessitando reoperação, sendo destas 3 recidivas, 2 fístulas digestivas, 1 hérnia diafragmática e 1 hérnia incisional. As complicações foram semelhantes em ambos os grupos, e a hérnia de hiato tipo IV foi o único preditor independente. CONCLUSÕES: O índice de massa corpórea não influencia nos resultados perioperatórios e a hérnia de hiato tipo IV é o único preditor independente de complicações.
RESUMO
ABSTRACT Introduction: Knowledge of validated primary causes of end-stage renal disease (ESRD) is extremely relevant in the realm of public health. The literature lacks validated studies on the primary causes of ESRD. Objective: The aim of this study was to estimate the prevalence of the causes of ESRD in a State Capital in Northeastern Brazil. Methods: This cross-sectional study was based on the analysis of medical records of patients on hemodialysis at five specialized centers in Fortaleza, CE, Brazil. Deaths and patients referred to other centers outside Fortaleza were excluded from the study. The data of 830 patients were initially collected, but 818 remained enrolled after the exclusion criteria were applied, the equivalent to 48% of the patents on dialysis in the city. Results: 61.1% of the patients were males. Twenty-two percent of all enrolled individuals were aged 60-69 years. Patient mean age was 55.7 ± 16 years. The most common validated cause of ESRD was unknown (35.3%), followed by diabetes mellitus (26.4%), adult polycystic kidney disease (6.2%), graft failure (6.2%), obstructive uropathy (5.7%), and primary glomerulonephritis (5.3%). Before validation, primary hypertension was the most frequent cause of chronic kidney disease (22.9%), decreased to 3.8% after validation. Conclusion: The data contradicted national studies reporting primary hypertension as the main cause of chronic kidney disease (CKD). A high rate of unknown causes and categorization bias were observed mainly in relation to primary hypertension as a cause of CKD, which affects the overall prevalence of causes of ESRD in patients on dialysis.
RESUMO Introdução: O conhecimento das causas primárias, validadas, de doença renal crônica terminal (DRCT) é primordial no contexto epidemiológico da doença. Existe uma lacuna na literatura em termos de estudos validados sobre tais causas. Objetivo: Estimar a prevalência das causas de DRCT em uma capital do Nordeste brasileiro. Métodos: Estudo transversal baseado na análise dos prontuários de pacientes em hemodiálise de cinco centros especializados em Fortaleza, CE. Foram excluídos casos de óbito no período da coleta e de transferências para outras unidades fora do município em questão. Coletou-se dados de 830 pacientes, restando 818 após aplicação dos critérios de exclusão, o correspondente a 48% dos pacientes que dialisam na cidade. Resultados: Observou-se que 61,1% dos pacientes eram do sexo masculino. A faixa etária mais prevalente foi 60 a 69 anos, 22%. A idade média foi 55,7 ± 16 anos. A causa mais comum de DRCT pós-validação foi indeterminada, 35,3%; seguida por diabetes mellitus, 26,4%; doença renal policística do adulto, 6,2%; falência do enxerto, 6,2%; uropatia obstrutiva, 5,7%; e glomerulonefrite primária, 5,3%. Antes da validação, a hipertensão primária foi a causa mais frequente de DRCT, com 22,9%, e, após validação, caiu para 3,8%. Conclusão: Os dados contrariam estudos nacionais que afirmam que a primeira causa de DRCT seria hipertensão primária. Evidenciou-se alta taxa de causas desconhecidas e viés de classificação, principalmente com relação à HAS primária como causa de DRCT, o que afeta a prevalência geral das causas de DRCT dos pacientes em diálise.
