There was an obvious cardiac autonomic improvement after surgery. Despite the improvement in exercise tolerance, patients undergoing bariatric surgery had lower maximum oxygen consumption in the analysis not corrected for body weight. The mean VORP before bariatric surgery was 141 s and was 111 s after the surgical procedure (p < 0.001). These results suggest an improvement in the recovery kinetics of oxygen consumption, a novel index of cardiac reserve capacity, on patients undergoing bariatric surgery.
Introduction: Infection of the surgical site is the common complication, with significant rates of morbidity and mortality, representing a considerable economic problem for the health system. Objective: To carry out a narrative review of the literature on surgical site infection and the principles of antibiotic prophylaxis to update the knowledge of its use in surgery. Method: Medline, Ovid, Google Scholar, National Library of Medicine (PubMed), Cochrane and SciELO were used for the research. The keywords used were “anti-bacterial agents”; “antibioticoprophylaxis” AND “surgical wound infection”. The inclusion criteria were articles of recent publication, with full texts available and performed in humans. Result: A total of 29 articles were evaluated and selected according to the eligibility criteria. Conclusion: Infection of the surgical site is the most common postoperative complication. The key point of its prevention is the combination of several interventions that aim to reduce risk factors, such as: compliance with the new guidelines of the Center for Disease Control and Prevention; the principles of the use of prophylactic antibiotics; factors and risk index of the surgical site; administration time; duration and dosage of antibiotics. These data are available in this article.
in a population with different socioeconomic limitations, RYGB maintained satisfactory results regarding weight loss, but inefficient follow-up may compromise the final result, especially with regard to nutritional deficiencies.
RESUMO Objetivo: apresentar uma análise descritiva dos resultados de um pacote de cuidados aplicado em pacientes obesos submetidos à cirurgia bariátrica, no que diz respeito ao controle de infecção. Métodos: um pacote de cuidados foi estruturado, visando a conter as taxas de infecção de sítio cirúrgico (ISC) em pacientes submetidos à cirurgia bariátrica. O pacote incluiu interrupção de tabagismo, banho com clorexidina 4% duas horas antes da cirurgia, cefazolina 2g em bolus na indução anestésica associada à administração da mesma droga com dose de 1g em infusão contínua, tricotomia apropriada, controle glicêmico, oxigênio suplementar, normotermia, controle da dor com morfina intrarraquidiana e remoção do curativo estéril 48 horas após a cirurgia. Todos os pacientes foram seguidos por 30 dias. Resultados: entre os 1.596 pacientes incluídos, 334 (20,9%) foram submetidos à cirurgia aberta e 1.262 (79,1%) à cirurgia videolaparoscópica. As taxas de ISC foram de 0,5% no grupo submetido à cirurgia laparoscópica e de 3% nos submetidos à cirurgia aberta. A incidência geral de ISC foi de 1%. Infecções intra-abdominal, do trato respiratório e do trato urinário ocorreram em 0,9%, 1,1% e 1,5% da amostra, respectivamente. Faixas mais elevadas de índice de massa corporal foram associadas a maiores incidências de ISC (p=0,001). Entre os pacientes com diabetes, 2,2% desenvolveram ISC, enquanto a taxa de infecção entre os não diabéticos foi de apenas 0,6%. Conclusão: o pacote de cuidados instituído, estruturado por estratégias centrais baseadas em evidências, associadas à medidas secundárias, foi capaz de manter baixas taxas de ISC após cirurgia bariátrica.
Purpose The aim of this study was to determine the real influence of bariatric surgery on the clinical evolution of patients infected with SARS-Cov-2 in the postoperative period. Methods We conducted a retrospective analysis including two groups of patients: those who presented COVID-19 before bariatric surgery and those who presented it within 3 months of postoperative. Primary outcome was related to the severity of COVID-19, measured by the following variables: presence of symptoms, need for hospitalization, ICU admission, and invasive ventilation. Laboratory markers for inflammatory response, glycemic status, and micronutrients were analyzed as secondary outcomes. Results From the 222 individuals operated on within the study period, only 66 (29.7%) presented COVID-19, 42 (18.9%) in the preoperative period and 24 (10.8%) after the procedure. Mean age was 36.3 ± 9.5 years and mean preoperative BMI was 39.9 ± 4.2 kg/m 2 . There were no statistically significant differences between the groups regarding symptoms presentation (92.9% × 87.5%, p = 0.66), need for hospitalization (11.9% × 16.7%, p = 0.713), ICU admission (4.8% × 4.2%, p = 1.000), and invasive ventilation (2.4% × 0.0%, p = 1.000). Regarding the quantitative variables, absolute lymphocyte count was significantly lower in the group who presented COVID-19 after surgery (1822.9 ± 482.2 × 2158.6 ± 552.9, p = 0.035). Conclusion Patients who had COVID-19 before and after sleeve gastrectomy did not differ with statistical significance for the presence of symptoms, need for hospitalization, ICU admission, and invasive ventilation.

Objective: to compare the improvements in lipid profile in patients undergoing sleeve gastrectomy (SG) and Rouxen-Y gastric bypass (RYGB). Methods: in a mixed cohort study, we evaluated 334 patients undergoing SG and 178 patients undergoing RYGB at the University Hospital of the Federal University of Pernambuco and at the Real Hospital Português de Beneficência, Recife, PE, Brazil. We measured serum levels of total cholesterol, LDL, HDL and triglycerides preoperatively and at three, six, 12 and 24 months follow-up. Results: the SG group consisted of 58 men and 276 women. In the group submitted to RYGB, there were 64 men and 114 women. The mean age was 37.2±20.5 years in the SG group and 41.9±11.1 years in the RYGB group. The preoperative mean BMI was 39.4±2.6kg/m 2 and 42.7±5.8kg/m 2 for the SG and RYGB groups, respectively. In the preoperative period, 80% of the patients had at least one abnormality in the lipid profile. Two years after surgery, there was improvement in total cholesterol, LDL, HDL and triglycerides in the group submitted to RYGB. In the group submitted to SG, after two years there was improvement in total cholesterol, HDL and triglyceride levels. Conclusion: both techniques resulted in improvements in the lipid profile, but the RYGB was more effective.

RESUMO Objetivo: comparar a prevalência das deficiências de micronutrientes nos pacientes submetidos à gastrectomia vertical (GV) e à derivação gástrica em Y de Roux (DGYR). Métodos: estudo comparativo de 576 pacientes submetidos à cirurgia bariátrica, 338 através de GV e 238 de DGYR e avaliados quanto às dosagens séricas de hemoglobina, ferro, ferritina, zinco e vitamina B12. Estas dosagens foram realizadas nos períodos pré-operatório e três, seis, 12 e 24 meses após a cirurgia, para análise e comparação das deficiências de micronutrientes entre as técnicas. Resultados: o grupo submetido à GV foi composto por 48 homens e 290 mulheres, com IMC médio de 39,4±2,6Kg/m2 e média de idade de 37,2±11 anos; o grupo submetido à DGYR foi composto por 77 homens e 161 mulheres, com IMC médio de 42,7±5,9Kg/m2 e média de idade de 41,9±11,1 anos. Após 24 meses, déficit de hemoglobina se fez presente em 24,4% dos pacientes submetidos à GV e 40% da DGYR (p=0,054); deficiência de ferro em 6,6% da GV e 15% da DGYR (p=0,127); déficit de ferritina em 17,8% da GV e 23,7% da DGYR (p=0,399); deficiência de zinco em 6,6% da GV e 30% da DGYR (p=0,002) e deficiência de B12 em 6,6% da GV e 8,7% da DGYR (p=0,844). Conclusão: pacientes submetidos à GV apresentaram níveis séricos de ferro e zinco superiores aos pacientes submetidos à DGYR, e a prevalência de déficit deste último micronutriente foi significativamente maior no grupo da DGYR.
BackgroundLiposarcoma of the gallbladder is an extremely rare sarcoma, with only five cases reported in the literature according to our knowledge.Case presentationA 71-year-old woman was referred to the Surgical Oncology Division of Napoleão Laureano Hospital (João Pessoa, PB, Brazil) due to a solid mass at the right side of the abdomen and fever, with no signs of jaundice. Abdominal ultrasonography and computed tomography (CT) evidenced an extensive gallbladder lobular formation adhered to the inferior border of the right hepatic lobe and cholelithiasis. The CT report suggested gallbladder liposarcoma. A cholecystectomy associated with resection of segments IV-B and V of the liver were performed. Intraoperative frozen sections were compatible with gallbladder sarcoma. Anatomopathological examination and immunohistochemistry confirmed dedifferentiated liposarcoma with foci of heterologous leiomyosarcomatous differentiation and undifferentiated fusocellular areas of high histological grade.ConclusionThis is the first case of dedifferentiated liposarcoma of the gallbladder to be reported.
