OBJETIVO: Analisar os resultados da incidência de infecção do sítio cirúrgico com três diferentes esquemas antimicrobianos. MÉTODO: No período de Janeiro de 1999 a Dezembro de 2004 foram realizadas 716 cirurgias para o tratamento da Obesidade mórbida, seguindo a técnica proposta por Fobi/Capella. Foram estudados comparativamente três grupos de pacientes: Grupo I - (185) em que foi realizada a profilaxia antimicrobiana com ampicilina/sulbactam, na dose de 3g em duas doses; Grupo II (280) em que a profilaxia foi com ceftriaxona na dose de 1g (dose única); e Grupo III (251) em que a profilaxia foi com ertapenem, na dose de 1 g (dose única). RESULTADOS: O resultado do presente estudo demonstra taxas de infecção do sítio cirúrgico de 3,78% no grupo de profilaxia com ampicilina-sulbactam, 6,81% no grupo de profilaxia com ceftriaxona e de 1,99% no grupo de ertapenem. Não houve diferença estatisticamente significativa entre o uso da associação ampicilina/sulbactam ou ceftriaxona com relação à incidência de infecção do sítio cirúrgico. No entanto, quando comparados os resultados do Grupo II (Ceftriaxona) com o Grupo III (Ertapenem), houve uma diferença estatisticamente sisgnificante. CONCLUSÃO: A utilização do ertapenem, de maneira profilática, no tratamento cirúrgico da obesidade mórbida, determinou taxas de infecção do sítio cirúrgico estatisticamente inferiores ao grupo de ceftriaxona e similar ao de ampicilina-sulbactam.
The quality of life was assessed through the Bariatric Analysis and Reporting Outcome System (BAROS) in the postoperative period of patients who underwent bariatric surgery, at the Prof. Fernando Figueira Institute of Integral Medicine -IMIP, a reference center of the Sistema Único de Saúde (SUS) in the Northeast of Brazil. This was a crosssectional, retrospective descriptive study of 66 patients who underwent Roux-en-Y gastroplasty between October 2013 and January 2014, and who were being followed-up. The variables studied before and after surgery were: body mass index (BMI), comorbidities and quality of life. For statistical analysis, the Macnemar and Stuart-Maxwell test was used, adopting the significance level of 5%. Among the 66 patients in the preoperative period, 87.9% had a BMI distribution of grade III obesity. By order of prevalence the comorbidities were: self-reported anxiety 87.9%, orthopedic disorders 86.4% and sleep disturbances 69.7%. In the postoperative period of the study sample, 12.1% of patients with grade III obesity were identified, with a statistical significance (p <0.001). More than 50% presented improved or very improved evaluations in aspects of self-esteem, physical, social, work and sexual; 100% referred to the quality of life as better or much better. It was concluded that bariatric surgery is an effective treatment for grade III obesity, as well as its comorbidities, and since it was evaluated through the BAROS protocol, it showed a positive impact on the quality of life of ex-obese patients.
