INCREASED RISK OF SYNCHRONOUS COLORECTAL LESIONS IN PATIENTS REFERRED FOR ENDOSCOPIC MUCOSAL RESECTION OF LATERAL SPREADING TUMORS.

BACKGROUND: Endoscopic mucosal resection is one of the most frequent therapeutic alternatives for large colorectal lateral spreading tumors. There are few data on the prevalence of synchronous lesions on these patients. OBJECTIVE: To describe the prevalence of synchronous colorectal lesions in patients referred for endoscopic mucosal resection of lateral spreading tumors >20 mm. METHODS: We reviewed the endoscopic database of our Department and identified adult patients who were referred for the resection of a colorectal lateral spreading tumor >20 mm and had a diagnostic colonoscopy performed up to six months before. The proportion of patients with at least one synchronous lesion was estimated. The following features were compared between patients with and without synchronous lesions: age, gender, bowel preparation quality and cecal intubation on index colonoscopy and therapeutic colonoscopy, serrated adenoma as index lesion. RESULTS: From December 2016 to November 2017, we identified 70 patients who fulfilled inclusion criteria. Median size of lesions was 25 mm (20-45). Eighty percent were located in the right colon and 35.71% were serrated adenomas. Synchronous lesion rate was 38.57%. Bowel preparation quality was similar in both groups when comparing both index and therapeutic colonoscopies. Patients with synchronous lesions had a higher proportion of serrated adenoma as index lesion than patients without synchronous lesions [51.85% vs 25.58%, OR 3.13 (1.13-8.68), P=0.03]. CONCLUSION: We found a high prevalence of synchronous lesions among patients with a large colorectal lateral spreading tumor. This risk seems to be increased if index lesions are serrated adenomas.

DESCRITORES CONTEXTO: A ressecção endoscópica de mucosa é uma das alternativas terapêuticas frequentes para grandes tumores colorretais de propagação lateral. Há poucos dados sobre a prevalência de lesões síncronas nesses pacientes. OBJETIVO: Descrever a prevalência de lesões colorretais síncronas em pacientes encaminhados para ressecção endoscópica da mucosa de tumores de disseminação lateral >20 mm. MÉTODOS: Realizou-se a revisão de banco de dados endoscópicos de nosso departamento e foram identificados pacientes adultos encaminhados para a ressecção de um tumor colorretal com propagação lateral >20 mm e que tiveram colonoscopia diagnóstica realizada até seis meses antes. Estimou-se a proporção de pacientes com pelo menos uma lesão síncrona. As seguintes características foram comparadas entre pacientes com e sem lesões síncronas: idade, sexo, qualidade da preparação intestinal e intubação cecal pelo índice de colonoscopia e adenoma serrilhado como lesão índice. RESULTADOS: De dezembro de 2016 a novembro de 2017, identificamos 70 pacientes que preencheram os critérios de inclusão. O tamanho mediano das lesões foi de 25 mm (20-45). Foram 80% situados no cólon direito e 35,71% eram adenomas serrilhados. A taxa de lesão síncrona foi de 38,57%. A qualidade da preparação intestinal foi semelhante em ambos os grupos comparando-se os índices e colonoscopia terapêutica. Pacientes com lesões síncronas apresentaram maior proporção de adenoma serrilhado como lesão índice do que pacientes sem lesões síncronas [51,85% vs 25,58%, or 3,13 (1,13-8,68), P=0,03]. CONCLUSÃO: Encontramos alta prevalência de lesões síncronas entre pacientes com grande tumor de propagação lateral colorretal. Este risco parece ser aumentado se as lesões índice forem adenomas serrilhados.

VITAMIN D DEFICIENCY AMONG INFLAMMATORYBOWEL DISEASE PATIENTS IN ARGENTINA: A CROSS-SECTIONAL STUDY.

BACKGROUND: An association has been established between low serum values of vitamin D and inflammatory bowel disease. There is a lack of evidence on whether this association is still observed in regions where sun exposure throughout the year is higher. OBJECTIVE: To compare the prevalence of vitamin D deficiency between inflammatory bowel disease patients and healthy controls. METHODS: Inflammatory bowel disease patients were consecutively enrolled as cases. Age and gender-matched healthy subjects who agreed to undertake a determination of serum vitamin D were enrolled as controls. Demographic features, medical treatment, need for hospital admission at diagnosis, steroid treatment, smoking, need for surgical treatment were evaluated as factors associated with vitamin D deficiency. RESULTS: Overall, 59 patients with a diagnosis of either Crohn's disease or ulcerative colitis were enrolled, as well as 56 controls. Median age was 41 years (19-79) and 56% were male. Vitamin D deficiency was observed in 66.1% of inflammatory bowel disease patients versus 21.42% of healthy controls (OR 7.15 (3.1-16.48), P=0.001). Among inflammatory bowel disease patients, male gender, disease duration, moderate-to-severe disease and hospital admission at the moment of diagnosis were found to be associated with vitamin D deficiency. On multivariate analysis, only longer disease duration [(OR 1.01 (1-1.06)] and hospital admission at diagnosis [(OR 5.63 (1.01-31.61)] were found to be significantly associated with the latter. CONCLUSION: Vitamin D deficiency was more frequent among inflammatory bowel disease patients. Longer disease duration and need for hospital admission at diagnosis were associated to vitamin D deficiency among these patients.

RESUMO CONTEXTO: Uma associação foi estabelecida entre os baixos valores séricos de vitamina D e doença inflamatória intestinal. Falta evidência se esta associação ainda é observada em regiões onde a exposição ao sol durante todo o ano é maior. OBJETIVO: Comparar a prevalência de deficiência de vitamina D entre pacientes com doença inflamatória intestinal e indivíduos controles saudáveis. MÉTODOS: Pacientes com doença inflamatória intestinal foram consecutivamente selecionados. Indivíduos saudáveis combinados da mesma idade e gênero que concordaram em fornecer uma determinação da vitamina D do soro foram considerados como controles. Características demográficas, tratamento médico, necessidade de admissão hospitalar no diagnóstico, tratamento de esteroides, tabagismo, necessidade de tratamento cirúrgico foram avaliados como fatores associados à deficiência de vitamina D. RESULTADOS: No geral, 59 pacientes com diagnóstico de doença de Crohn ou colite ulcerosa foram observados, bem como 56 controles. A idade mediana era de 41 anos (19-79) e 56% eram do sexo masculino. A deficiência de vitamina D foi observada em 66,1% dos pacientes com doença inflamatória intestinal versus 21,42% dos controles saudáveis (OR 7,15 (3.1-16.48), P=0,001). Entre os pacientes com doença inflamatória intestinal, sexo masculino, duração da doença, doença de moderada a severa e admissão hospitalar no momento do diagnóstico foram associados com a deficiência de vitamina D. Na análise multivariada, apenas a duração da doença [(OR 1; 1 (1-1,06)] e a admissão hospitalar no diagnóstico [(OR 5,63 (1,01-31,61)] foram encontradas significativamente associadas ao último. CONCLUSÃO: A deficiência de vitamina D foi mais frequente entre os pacientes com doença inflamatória intestinal. Maior duração da doença e necessidade de admissão hospitalar no diagnóstico foram associadas à deficiência de vitamina D entre esses pacientes.
