FISTULIZING PERIANAL CROHN'S DISEASE: IS THE PATIENT'S SEX A BURDEN? A SYSTEMATIC REVIEW.

BACKGROUND: Fistulizing perianal Crohn's disease poses a treatment challenge, and researchers postulate that this phenotype in young male patients could have a worst outcome. OBJECTIVE: Thus, the aim of this study was to assess whether sex influences the response to treatment for these patients. METHODS: This systematic review (PROSPERO CRD42022319629) was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. We selected articles published in English, Spanish, Portuguese, and Italian between 2010 and 2020 in the PubMed and Science Direct databases. According to the PICO acronym, prospective studies in patients older than 18 years with the objective of treating fistulizing perianal Crohn's disease were selected. Studies in pediatric populations, retrospective, without treatment objectives, and that included only rectovaginal fistulas or a single sex were excluded. Study quality was assessed using the Cochrane risk of bias tool and Newcastle-Ottawa scale. RESULTS: Of the 1887 articles found, 33 were included. Most studies used anti-TNF drugs as treatment (n=11). Ten studies had subgroup analyses; of them, the two studies reporting sex differences used infliximab and adalimumab as treatment and showed that women had a longer fistula closure time than men. CONCLUSION: This systematic review showed that few data corroborate the difference between sexes in the treatment of fistulizing perianal Crohn's disease, possibly having a greater relationship with the phenotype. However, considering the lack of results, further studies with this objective and with standardization of fistulas and response assessment methods are needed.

RESUMO Contexto: A doença de Crohn perianal fistulizante representa um desafio de tratamento, e postula-se que esse fenótipo em pacientes jovens do sexo masculino poderia ter um pior resultado. Objetivo: O objetivo deste estudo foi avaliar se o sexo influencia a resposta ao tratamento desses pacientes. Métodos: Esta revisão sistemática (PROSPERO CRD42022319629) foi conduzida de acordo com o protocolo Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Foram selecionados artigos publicados em inglês, espanhol, português e italiano entre 2010 e 2020 nas bases de dados PubMed e Science Direct. De acordo com o acrônimo PICO, foram selecionados estudos prospectivos em pacientes maiores de 18 anos com objetivo de tratamento da doença de Crohn perianal fistulizante. Foram excluídos estudos em populações pediátricas, retrospectivos, sem objetivos de tratamento e que incluíssem apenas fístulas retovaginais ou um único sexo. A qualidade dos estudos foi avaliada usando a ferramenta de risco de viés Cochrane e a escala Newcastle-Ottawa. Resultados: Dos 1.887 artigos encontrados, 33 foram incluídos. A maioria dos estudos utilizou medicamentos anti-TNF como tratamento (n=11). Dez estudos tiveram análises de subgrupos; deles, os dois estudos que relataram diferenças entre os sexos usaram infliximabe e adalimumabe como tratamento e mostraram que as mulheres tiveram um tempo de fechamento da fístula maior que os homens. Conclusão: Esta revisão sistemática mostrou que poucos dados corroboram a diferença entre os sexos no tratamento da doença de Crohn perianal fistulizante, possivelmente tendo maior relação com o fenótipo. Porém, dada à falta de resultados, são necessários mais estudos com esse objetivo e com padronização das fístulas e métodos de avaliação da resposta.

COVID-19 AND DIGESTIVE ENDOSCOPY: EMERGENCY ENDOSCOPIC PROCEDURES AND RISK FACTORS FOR UPPER GASTROINTESTINAL BLEEDING.

BACKGROUND: The COVID-19 pandemic has changed digestive endoscopy services around the world. OBJECTIVE: This study aimed to measure the number of urgent/emergency endoscopic procedures performed in a Brazilian hospital, comparing it to the same period in the previous year, and to identify risk factors in COVID-19 patients undergoing endoscopic procedures for upper gastrointestinal bleeding (UGIB). METHODS: This was a retrospective, cross-sectional, observational, single-center study. The study evaluated urgent/emergency endoscopic procedures performed on adult patients from March to August in 2019 and 2020. The COVID-19 patients included were diagnosed using RT-PCR, aged over 18 years with complete medical record information. The variables evaluated were age, sex, comorbidities, length of stay, D-dimer, need for intensive care unit (ICU) and mechanical ventilation. Student's t-test for independent samples or the non-parametric Mann-Whitney test was used to compare quantitative variables. Categorical variables were analyzed using Fisher's exact test. A P-value <0.05 indicated statistical significance. RESULTS: A total of 130 urgent/emergency endoscopic procedures were performed in 2020 and 97 in 2019. During the study period, 631 patients were hospitalized due to COVID-19, of whom 16 underwent urgent/emergency endoscopic procedures, 10 (1.6%) due to UGIB. Of the variables analyzed, the need for ICU and/or mechanical ventilation during hospitalization was statistically significant as a risk factor for UGIB. CONCLUSION: This study showed increased urgent/emergency endoscopic procedures during the pandemic at the study site. Among the patients hospitalized with the novel coronavirus, there is a higher risk for UGIB in those needing ICU and/or mechanical ventilation.

RESUMO CONTEXTO: A pandemia da COVID-19 tem alterado o funcionamento de serviços de endoscopia digestiva pelo mundo. OBJETIVO: O presente estudo tem por objetivo medir o número de exames endoscópicos de urgência/emergência realizados em um hospital público brasileiro, comparando-o ao mesmo período do ano anterior, além de avaliar os fatores de risco dos pacientes com COVID-19 que realizaram exame endoscópico por hemorragia digestiva alta (HDA). MÉTODOS: Estudo retrospectivo, transversal, observacional e unicêntrico. Foram avaliados todos os exames endoscópicos de urgência/emergência realizados em pacientes acima de 18 anos, nos períodos de março a agosto dos anos de 2019 e 2020. Os pacientes com COVID-19 incluídos foram diagnosticados por RT-PCR, acima de 18 anos, com informações completas em prontuário. As variáveis avaliadas foram: tipo de exame endoscópico, idade, sexo, comorbidades, tempo de internação, d-dímero, necessidade de UTI e ventilação mecânica durante a internação. A comparação dos grupos em relação a variáveis quantitativas foi feita através do teste t de Student para amostras independentes ou o teste não-paramétrico de Mann-Whitney. As variáveis categóricas foram avaliadas pelo teste exato de Fisher. Valores de P<0,05 indicaram significância estatística. RESULTADOS: Observaram-se 130 exames endoscópicos de urgência/emergência no período avaliado em 2020, e 97 em 2019. No período do estudo foram internados 631 pacientes por COVID-19, dos quais 16 realizaram exame endoscópico de urgência/emergência, sendo 1,6% por HDA. Dentre as variáveis analisadas, necessidade de UTI e/ou ventilação mecânica durante o internamento foram estatisticamente significativos como risco para desenvolvimento de HDA. CONCLUSÃO: O presente estudo mostra que para a realidade local houve incremento de exames endoscópicos de urgência/emergência durante a pandemia. Dentre os pacientes internados com o novo coronavírus, há maior risco de HDA naqueles que necessitam de UTI e/ou ventilação mecânica.

ILEITIS - DO ENDOSCOPIST AND PATHOLOGIST SPEAK THE SAME LANGUAGE?

BACKGROUND: Ileitis is defined as an inflammation of the ileum, which is evaluated during colonoscopy. Biopsies should be performed on altered ileus, aiding to the diagnosis. OBJECTIVE: Evaluate the correlation of anatomopathological findings on ileitis between pathologists and endoscopists. METHODS: A retrospective, cross-sectional study, between 2013 and 2017. Examination report, indications for colonoscopy, and medical records were evaluated to identify whether the colonoscopic findings were clinically significant. Anatomopathological samples were reviewed by a pathologist expert in gastrointestinal tract. Patients over 18 years of age who had undergone ileoscopy were included, whereas patients below 18 years of age and those with previous intestinal resections were excluded. The correlation was assessed using the kappa coefficient index. RESULTS: A total of 5833 colonoscopies were conducted in the study period and 3880 cases were included. Ileal alterations were observed in 206 cases, with 2.94% being clinically significant. A hundred and sixty three biopsies were evaluated using the kappa index, resulting in agreement among pathologists of 0.067 and among pathologist and endoscopist of 0.141. CONCLUSION: It was observed that despite the low concordance between pathologists and endoscopists, there was no change in patient outcomes. This study confirms the importance of knowledge of the main anatomopathological changes related to ileitis by pathologists and endoscopists, making the best diagnosis and follow-up.

ILEOSCOPY: WHEN ILEAL EVALUATION IS NOT MANDATORY DURING COLONOSCOPY.

BACKGROUND: Ileitis is defined as ileal inflammation, with several etiologies, including inflammatory bowel disease (IBD), and can be evaluated during the colonoscopy exam, but its mandatory evaluation is discussed, because of few diagnosis and procedure time. OBJECTIVE: This study aims to evaluate the correlation of colonoscopic ileitis with the clinical presentation, in order to identify the cases where ileal examination is mandatory. METHODS: A retrospective, cross-sectional study was conducted between 2013 and 2017. The examination report, indications for colonoscopy, and medical records were evaluated in order to identify whether the colonoscopic findings were clinically significant. Patients over 18 years of age who had undergone ileoscopy were included, whereas patients below 18 years of age, those with previous intestinal resections, and repeated examinations of the same patient in the study period were excluded. The estimated association measure was the odds ratio with 95% confidence intervals. P-values <0.05 indicated statistical significance. RESULTS: A total of 3382 cases were included. Among these participants, 64.5% were females and the average age was 56.9±13.1 years (18-89 years). Ileal alterations were observed in 5.3% of the patients, with 2.69% being clinically significant between all patients, and 0.96% excluding those with IBD. There was a positive correlation between the ileitis findings and IBD control examinations and a negative correlation in screening and change in bowel habit indications. Among the indications with ileitis clinically significant, IBD control still had a positive correlation, 'diarrhea' and 'others' did not show a statistical significance, and all other indications presented a negative correlation for ileal assessment. CONCLUSION: Ileal evaluation in only mandatory in IBD control. When the main colonoscopy objective is detecting colonic neoplasms, ileoscopy is unnecessary.

RESUMO CONTEXTO: Ileíte é definida como uma inflamação ileal, que pode ser avaliada durante a colonoscopia. Biópsias devem ser realizadas em íleos alterados, acrescentando na definição diagnóstica. OBJETIVO: Avaliar a correlação de achados anatomopatológicos das ileítes entre patologistas e endoscopistas. MÉTODOS: Estudo retrospectivo, transversal, entre os anos de 2013 e 2017. Foram avaliados laudos de exames, indicações e prontuários para identificar quando os achados colonoscópicos foram significativos. As amostras de anatomopatologia foram revisadas por um patologista especialista em trato gastrointestinal. Foram incluídos pacientes acima de 18 anos, com ileoscopia, e excluídos pacientes menores de 18 anos e os com ressecções intestinais prévias. A correlação foi avaliada utilizando-se o coeficiente kappa. RESULTADOS: Durante o período do estudo foram realizadas 5833 colonoscopias, das quais 3880 foram incluídas. Alterações ileais foram observadas em 206 casos, com 2,94% sendo clinicamente significativo. Cento e sessenta e três biópsias foram avaliadas, resultando em coeficiente kappa entre patologistas de 0,067 e entre patologista e endoscopista de 0,141. CONCLUSÃO: Foi observado que a despeito da baixa concordância entre patologistas e endoscopistas, não houve mudança no desfecho clínico do paciente. Esse estudo confirma a importância do conhecimento dos achados anatomopatológicos principais das ileítes entre patologistas e endoscopias, fazendo o melhor diagnóstico e seguimento.

RESUMO CONTEXTO: Ileíte é definida como inflamação ileal, com diversas etiologias, incluindo doença inflamatória intestinal (DII), e pode ser avaliada durante o exame de colonoscopia, mas sua avaliação obrigatória é discutida, devido aos poucos diagnósticos e tempo de procedimento. OBJETIVO: O objetivo deste estudo é avaliar a correlação da ileíte colonoscópica com a apresentação clínica, a fim de identificar os casos em que o exame ileal é obrigatório. MÉTODOS: Foi realizado um estudo transversal retrospectivo entre 2013 e 2017. O laudo do exame, as indicações para colonoscopia e os prontuários médicos foram avaliados para identificar se os achados colonoscópicos eram clinicamente significativos. Pacientes maiores de 18 anos submetidos à ileoscopia foram incluídos, enquanto pacientes menores de 18 anos, aqueles com ressecções intestinais prévias e exames repetidos do mesmo paciente no período de estudo foram excluídos. A medida de associação estimada foi o odds ratio com intervalos de confiança de 95%. Valores de P <0,05 indicaram significância estatística. RESULTADOS: Foram incluídos 3382 casos. Desses, 64,5% eram mulheres e a média de idade foi de 56,9±13,1 anos (18-89 anos). Alterações ileais foram observadas em 5,3% dos pacientes, sendo 2,69% clinicamente significativos entre todos os pacientes e 0,96% excluindo aqueles com DII. Houve uma correlação positiva entre os achados de ileíte e exames de controle de DII e uma correlação negativa no rastreamento e alteração de hábito intestinal. Entre as indicações com ileíte clinicamente significativa, o controle de DII ainda teve uma correlação positiva, 'diarreia' e 'outros' não apresentaram significância estatística, e todas as outras indicações apresentaram correlação negativa para avaliação ileal. CONCLUSÃO: A avaliação ileal é obrigatória apenas no controle de DII. Quando o objetivo principal da colonoscopia é detectar neoplasias colônicas, a ileoscopia é desnecessária.

Tratamento colonoscópico de íleo biliar: relato de um caso / Colonoscopic treatment of gallstone ileus: a case report

O íleo biliar representa de 1 a 4% das causas de obstrução mecânica do trato gastrointestinal, causado por um cálculo de origem biliar quando atinge a luz intestinal através de uma fístula bilioentérica. O seu tratamento normalmente é cirúrgico através da enterolitotomia, com ou sem realização de colecistectomia e correção da fístula bilioentérica no mesmo tempo cirúrgico. Relata-se o caso de um paciente de 78 anos com obstrução intestinal ao nível do íleo terminal. Devido ao risco cirúrgico elevado optou-se pela realização de colonoscopia de urgência, que extraiu um cálculo de 2,1cm, impactado na válvula ileocecal. O paciente evoluiu bem após o procedimento, sendo optado pelo tratamento conservador da vesícula biliar e fístula durante o internamento. Conclui-se que pacientes de alto risco se beneficiam com procedimentos menos invasivos, como os endoscópicos, que além de diagnósticos podem ser terapêuticos

The gallstone ileus represents 1 to 4% of the causes of mechanical obstruction from gastrointestinal tract, caused by a gallstone when it reaches the intestinal lumen through a bilioenteric fistula. The treatment is usually the enterolithotomy, with or without cholecystectomy and correction of the bilioenteric fistula at the same surgical time. We report a case of a patient, 78 years old, with intestinal obstruction at the level of the ileocecal valve. The examination showed abdominal distension and pain, with no signs of peritonitis. Due to the surgical risk, a emergency colonoscopy was performed, which removed a 2.1 cm gallstone impacted into the ileocecal valve. The patient evolved well after the procedure and it was chosen the conservative approach to the gallbladder and fistula during the same hospital stay. We conclude that the high-risk patients could benefit from less invasive treatments, such as endoscopy, which can be diagnoses and therapeutic

ProCura - a arte da vida: um projeto pela humanização na saúde / ProCura - the art of living: a project for the humanization of health care

As modificações da medicina tornaram o conhecimento biomédico soberano, gerando a perda da relação médico-paciente, o que fomentou o movimento pela humanização. Na Universidade Federal do Paraná (UFPR), formou-se o projeto de extensão "ProCura - a arte da vida", a fim de implementar a humanização entre os alunos e em suas relações profissionais. Seus objetivos se baseiam nos pilares: relação estudante-paciente, relação estudante-estudante e formação teórico-reflexiva, e se subdividem nos grupos Cineclube, Clown e Contação de Histórias. De 2010 a 2012, 79 alunos participaram e atenderam 905 pacientes, 505 acompanhantes e 107 funcionários. Apesar de limitações de alcance no que concerne a atingir todos os alunos do Setor de Ciências da Saúde, o projeto pretende fomentar a discussão entre grupos e que seus ideais e atividades se espalhem e permeiem o meio acadêmico.

Changes in medicine have promoted biomedical knowledge to a position of sovereignty. Coupled with the decline of the physician-patient relationship, this has brought about the the humanization movement. At the Federal University of Paraná (UFPR), a community outreach project entitled "ProCura - the art of living" has been created to implement humanization among students and in their professional relationships. Its objectives are based on three pillars: student-patient relationship, student-student relationship and theoretical-reflexive training, subdivided into groups named Cineclube, Clown and Contação de Histórias. Between 2010 and 2012, 79 students participated in the project, attending to 905 to patients, 505 companions and 107 employees. Despite its limited scope as regards reaching all Department of Health Sciences students, the Project aims to promote discussion between groups and disseminate their ideals and activities throughout academic circles.
