Abstract: montreal classification (mc) succeeded vienna classification (vc) in the characterization of patients with crohn′s disease (cd). in order to evaluate the differences and potential advantages of the first regarding the last one and validate the mc through the longitudinal analysis of the phenotypic variation of this population, 122 crohn′s patients were retrospectively analyzed and classified according to both classifications. the evolution of both subgroups and the need for surgery was analysed. results showed that mc reclassified 6 patients in the criteria age at diagnosis (a), 4 in the criteria location (l) and 18 in the criteria behaviour (b). the disease location (l) remained stable. the behaviour (b) by the vc classification changed at 3 and 5 years. 41,8% of patients underwent major surgery. a higher association between the need for surgery and the group b3 of mc was identified. there were no statistically significant differences between the survival curves and sex, smoking and age at diagnosis. conclusion: the mc is more sensitive in the phenotypic evaluation of behaviour of cd, especially after exclusion of perianal disease from the category penetrating disease. the classification of cd by phenotypic pattern could possibly, in future, be applied to predict its natural history.

Abstract: introduction: suspected crohn?s disease (cd) is a common indication for capsule enteroscopy (ce). however, lesions are nonspecific and no gold standard is available for diagnosing cd. lewis score (ls) measures inflammatory activity based on oedematous villous appearance, ulcers and stenoses. aim: to evaluate the role of sl in the diagnosis of cd in clinical practice. methods: thirty patients who underwent ce for suspected cd were included and followed up for at least six months. inflammatory activity was classified in three levels: clinically insignificant (score<135), mild (135≤score≤790) or moderate to severe (score > 790). results: diagnosis of cd was established in 10 patients (33%). clinically significant inflammatory activity (score ≥ 135) had a positive predictive value (vpp) = 75%, negative predictive value (vpn) = 94%, sensitivity (s) = 90% and specificity (e) = 85% for the diagnosis of cd. conclusions: ls seems to be a useful index in the setting of suspected cd, increasing the objectivity of ce findings; it also has a good correlation with the diagnosis established during follow-up.

Enteroscopia por cápsula na suspeita de doen a de Crohn: há lugar para o Score de Lewis na prática clínica? Diagnosis of Crohn’s disease by capsule enteroscopy: is there a role for Lewis Score in clinical practice?

Abstract: INTRODU O: A suspeita de Doen a de Crohn (DC) é uma indica o frequente para a realiza o de enteroscopia por cápsula (EC). No entanto, os achados endoscópicos s o inespecíficos e n o existem critérios validados ou um gold-standard para o diagnóstico da doen a. O Score de Lewis (SL) valoriza a presen a de edema vilositário, úlceras e estenoses, permitindo classificar o nível de actividade inflamatória. OBJECTIVOS: Avaliar a utilidade do SL na prática clínica, enquanto contributo para o diagnóstico da DC. MéTODOS: Foram incluídos trinta doentes consecutivos com suspeita de DC, submetidos a EC e com um follow-upmínimo de seis meses. A actividade inflamatória foi classificada em três níveis: n o significativa (score < 135); ligeira (135 ≤ score ≤ 790) ou moderada a severa (score > 790). RESULTADOS: Foi estabelecido o diagnóstico de DC em 10 doentes (33%). A presen a de actividade inflamatória significativa (score ≥ 135), apresentou um Valor Preditivo Positivo (VPP) = 75%, Valor Preditivo Negativo (VPN) = 94%, Sensibilidade (S) = 90% e Especificidade (E) = 85% para o diagnóstico de DC. CONCLUS ES: A utiliza o do SL parece ser um indicador útil na suspeita de DC, permitindo aumentar a objectividade da interpreta o dos achados endoscópicos e apresentando uma boa correla o com o diagnóstico estabelecido durante o follow-up.

Abstract: A Classifica o de Montreal (CM) sucedeu à de Viena (CV) na caracteriza o dos doentes com Doen a de Crohn (DC). Com o objectivo de avaliar as diferen as e potenciais vantagens da primeira em rela o à última e validar a CM através da análise longitudinal da varia o fenotípica desta popula o, analisaram-se retrospectivamente 122 doentes com DC classificados segundo as CV e CM. Avaliou-se a evolu o dos subgrupos e a necessidade de cirurgia. Nos resultados verificou-se que a CM reclassificou 6 doentes no critério idade de diagnóstico (A), 4 no critério localiza o (L) e 18 no critério comportamento (B). A localiza o (L) da doen a permaneceu estável. O comportamento (B) pela CV modificou-se aos 3 e 5 anos. Foram submetidos a cirurgia major 41,8% dos doentes. Identificou-se uma maior associa o entre a necessidade de cirurgia e o grupo B3 da CM. N o se verificaram diferen as estatisticamente significativas entre as curvas de sobrevivência e as variáveis sexo, tabaco e idade de diagnóstico. CONCLUS O: A CM é mais sensível na avalia o fenotípica do comportamento da doen a, principalmente após a exclus o da doen a perianal da categoria doen a penetrante. A classifica o da DC por padr o fenotípico poderá eventualmente, no futuro, ser aplicada para predizer a sua história natural.
