PURPOSE: To evaluate the diagnosis improvement of EUS-FNA when using ROSE performed by the endosonographer. METHODS: A retrospective study was conducted. A total of 48 pancreatic solid masses EUS-FNA were divided into two groups according to the availability of on-site cytology (ROSE) - the first 24 patients (group A-without ROSE) and the latter 24 cases (group B-with ROSE). Sensitivity, specificity, positive predictive value, negative predictive value, accuracy, complications and inadequacy rate of EUS-FNA were determined and compared. RESULTS: Among the 48 EUS-FNA, the overall performance was: sensitivity 82%; specificity 100%; positive predictive value (PPV) 100%; negative predictive value (NPV) 70% and accuracy 87%. The sensitivity of the Group A was 71%, versus 94% in-group B (p=0.61). Moreover, the negative predictive value was 58% versus 87% (p=0.72). The accuracy rate increased from 79% to 96% (p=0.67) in the ROSE group. The number of punctures was similar between the groups. No major complications were reported. CONCLUSION: Rapid on-site cytopathological examination, even when performed by the endosonographer, may improve the diagnostic performance in the diagnosis of solid pancreatic lesions, regardless of the slight increase in the number of punctures.
ABSTRACT Clostridium difficile is the major etiological agent of pseudomembranous colitis and is found in up to 20% of adult inpatients. The recommended treatment is antibiotic therapy with metronidazole and/or vancomycin. However, the recurrence rate may reach up to 25% and it increases in each episode. The newest alternative to treat diarrhea due to recurrent Clostridium difficile is fecal microbiota transplantation. The procedure was performed in 12 patients, with a 6-month follow-up on 10 of them. Of the ten cases, bacterial recurrence was diagnosed in only one patient, after a course of antibiotic to treat urinary tract infection, without presenting with diarrhea. The particularity of our study, besides being an unprecedented event in South America, is the way to perform the infusion of fecal microbiota by enteroscopy.
RESUMO O Clostridium difficile é o principal agente etiológico da colite pseudomembranosa e está presente em até 20% dos adultos hospitalizados. O tratamento recomendado é a antibioticoterapia com metronidazol e/ou vancomicina. No entanto, a taxa de recidiva chega a 25% e aumenta conforme a recorrência. A mais recente alternativa para o tratamento da diarreia por Clostridium difficile recorrente é o transplante de microbiota fecal. Realizamos 12 casos, tendo 10 deles ocorridos há mais de 6 meses. Desses dez casos, houve recidiva bacteriana em apenas um deles, após novo ciclo de antibiótico para tratamento de infecção do trato urinário, sem a presença de diarreia. A particularidade da nossa casuística, além de ser um fato inédito na América do Sul, deveu-se à maneira de realizar a infusão da microbiota fecal, que foi por via enteroscópica.
