ABSTRACT
BACKGROUND: This study aimed to evaluate the outcomes of 67 patients who underwent revisional bariatric surgeries over a 29-year period in a Brazilian public hospital. METHODS: The records of all patients who underwent revisional bariatric surgery from January 1987 to December of 2016 at our hospital were analyzed for weight loss and complications. Descriptive statistics and paired t tests were computed. RESULTS: Sixty-seven patients were included in the study. The primary surgeries previously performed on these patients were biliopancreatic diversion with duodenal switch (BPD-DS) (37 cases, 55.2%), jejunoileal bypass (JIB) (24 cases, 35.8%), sleeve gastrectomy (4 cases, 5.9%), Roux-en-Y gastric bypass (RYGB) (1 case, 1.5%), and laparoscopic adjustable gastric band (1 case, 1.5%). The indications for revisional surgery were as follows: malnutrition in 29 cases (43.3%), failure to lose weight in 27 cases (40.3%), weight regain in 5 cases (7.5%), and untreatable diarrhea in 6 cases (9.2%). Most revisional surgeries were performed using JIB or BPD-DS. Operative mortality was higher after the revisional procedures compared with that following the primary bariatric surgeries. CONCLUSIONS: Most patients requiring a revisional surgery had undergone a primary BPD-DS or JIB. Severe and untreatable malnutrition and diarrhea were the main indications for the revisional procedures. RYGB produced significant and sustainable weight loss and exhibited a low risk of malnutrition or requiring revisional surgery.

Abstract Our aim was to investigate if single nucleotide polymorphisms (SNPs) located in the 5′ regions of leptin (LEP, -2548 G > A, rs7799039), resistin (RETN, -420 C > G, rs1862513) and adiponectin (ADIPOQ, -11391 G > A, rs17300539 and -11377 C > G, rs266729) genes were related to changes in body mass index (BMI) and metabolic variables after bariatric surgery in 60 extremely obese individuals. At baseline, ADIPOQ -11391 A-allele carriers showed higher plasma adiponectin and lower total cholesterol levels when compared to G/G homozygotes. Approximately 32 months post-surgery, a mean reduction of 35% in BMI and an important improvement in metabolic profiles were observed. In addition, for the ADIPOQ -11377 polymorphism, a higher decrease in lipid profile was associated to the C/C genotype. Moreover, individuals bearing the A-C haplotype for the two ADIPOQ SNPs were more prone to show a reduction in low-density lipoprotein levels after bariatric surgery (-43.0% A-C carriers vs. -18.1% G-G carriers, p = 0.019). We did not find any association of leptin and resistin SNPs with the clinical parameters analyzed. In summary, our results indicate that the A-C haplotype is a predictor of better lipid profile post-surgery and the studied SNPs in ADIPOQ gene are associated to changes in metabolic variables in obese individuals.

ABSTRACT
BACKGROUND: Obesity is a worldwide prevalent disease and is an underlying factor of non-alcoholic fatty liver disease (NAFLD). It has been understood as a chronic inflammatory state, being associated with the production of adipokines. The aim of this study was to analyze the levels of adipokines in the serum, visceral, and subcutaneous fat and to compare them with hepatic histopathology in morbidly obese patients. METHODS: This is a cross-sectional observational study, which analyzed the findings of liver biopsy in patients undergoing bariatric surgery and who had performed analysis of adipokines mRNA expression (adiponectin-ADIPOQ, leptin-LEP, and resistin-RETN) in subcutaneous and visceral adipose tissue and circulating adipokines in serum. Liver biopsies performed were evaluated according to Kleiner criteria. RESULTS: The study analyzed 25 patients undergoing bariatric surgery. The sample was composed exclusively of women. There was a predominance of NAFLD, with 21 patients (84%) with intrahepatic fat accumulation. Twelve patients presented non-alcoholic steatohepatitis (NASH). Glycated hemoglobin levels (HbA1c) were elevated in NASH patients. ADIPOQ levels were directly correlated with high-density lipoprotein (HDL) cholesterol levels and inversely correlated with triglycerides and total cholesterol. LEP levels showed an inverse relationship with the degree of steatosis, and RETN levels showed an inverse relationship with fibrosis stages. CONCLUSION: Serum LEP levels were reduced in the presence of increased levels of intrahepatic fat, and serum levels of RETN were diminished in the presence of NASH. HbA1c levels were higher in the presence of NASH, indirectly reflecting insulin resistance. Moreover, ADIPOQ levels were related to blood lipid profile.

OBJECTIVE: To assess immediate postoperative and late complications in patients with inguinal hernia undergoing surgical correction by Gilbert technique, using the Prolene Hernia System (HPS). METHODS: We surveyed all patients undergoing inguinal hernia repair with PHS mesh at The Sao Lucas Hospital--PUCRS, from January 2001 to october 2006. Information was retrospectively collected through telephone calls and chart review. The protocol for data collection included epidemiological aspects, as well as immediate and late complications. RESULTS: ninety-six patients were enrolled. We identified six (6.25%) complications in different patients, none of which resulting in death. Two patients (2.08%) had seroma; hematoma was identified in one patient (1.04%); one patient (1.04%) had wound infection. Two patients (2.08%) had scrotal edema. After a mean follow up of 49.25 months (range 16 to 86.12) two patients (2.08%) had chronic pain and one patient (1.04%) had hernia recurrence twenty-six months after surgery. CONCLUSION: The repair of inguinal hernia with PHS is a safe, effective and reproducible method, with low complication and recurrence rates or long term symptoms.

OBJETIVO: Aferir complicações pós-operatórias imediatas e tardias em pacientes portadores de hérnia inguinal, submetidos à correção cirúrgica pela técnica de Gilbert1, com utilização do Sistema Prolene de Hérnia (SPH). MÉTODOS: Foram pesquisados todos os pacientes submetidos à herniorrafia inguinal com tela PHS no Hospital São Lucas da PUCRS no período de janeiro de 2001 até ourubro de 2006. As informações foram coletadas de modo retrospectivo, através de contato telefônico e revisão de prontuários. O protocolo de coleta de dados contemplou os aspectos epidemiológicos, bem como as complicações imediatas e tardias. RESULTADOS: Foram incluídos 96 pacientes. Foram identificadas seis (6,25 por cento) complicações, em pacientes distintos; nenhuma complicação com óbito. Dois pacientes (2,08 por cento) apresentaram seroma; hematoma foi identificado em um paciente (1,04 por cento); um paciente (1,04 por cento) apresentou infecção de ferida operatória. Dois pacientes (2,08 por cento) apresentaram edema escrotal. Após seguimento médio de 49,25 meses (16-86,12) dois pacientes (2,08 por cento) apresentaram dor crônica e um paciente (1,04 por cento) apresentou recorrência, com vinte e seis meses de pós-operatório. CONCLUSÃO: O reparo de hérnias inguinais com tela PHS é um método seguro, eficaz, facilmente reprodutível e com baixas taxas de complicações, recorrência ou sintomas em longo prazo.
