CARACTERIZAÇÃO DAS ENDOSCOPIAS DIGESTIVAS ALTAS REALIZADAS NO MUNICÍPIO DE MOSSORÓ-RN / CHARACTERIZATION OF HIGH DIGESTIVE ENDOSCOPIES PERFORMED IN THE MUNICIPALITY OF MOSSORÓ-RN

Objetivou-se caracterizar as EDA realizadas na Comunidade de Saúde de Mossoró, RN, no período de 2008 a 2013, definindo a taxa de exames normais e a prevalência dos principais achados sugestivos de patologias digestivas. Trata-se de um estudo transversal e retrospectivo, no qual se analisou 10311 laudos de EDA. As análises estatísticas foram realizadas pelo SPSS (Statistical Package for the Social Sciences, versão 20.0), com nível de confiança95% e um p < 0,05, utilizando-se testes Qui-quadrado. Pelos dados levantados, constatamos que a EDA é um exame prático e seguro, com raríssimas complicações, sendo a agitação e a presença de alimento no estômago as limitações mais comuns. Na análise descritiva geral observou-se que a maioria dos exames foi realizada no gênero feminino, formando mais de 70% da amostra total. A faixa etária predominante, independente do gênero, foi 41 a 60 anos. As patologias frequentes no segmento esofágico foram as Esofagites. No segmento gástrico, a maior frequência de achados foram as Gastrites, que são mais frequentes com o avançar da idade. Na Transição Gastroduodenal, as úlceras de Canal Pilórico são os achados mais descritos, mas observamos também modestos achados de duodenites. No duodeno, os principais achados foram úlceras duodenais, seguidas pelas duodenites e sinais de atrofia. Portanto, as EDA são mais realizadas no gênero feminino, mas apresentam maior percentual de exames normais, sendo a maior frequência de achados encontrada no gênero masculino. Assim, após analisar as 10.311 EDA, é possível prever os achados mais comuns encontrados a EDA.

This study aimed to characterize the EDA held in Mossoro Health Community, RN, from 2008 to 2013, setting the rate of normal examinations and the prevalence of the main findings suggestive of digestive pathologies. It is a cross-sectional retrospective study, which analyzed 10,311 reports of EDA. Statistical analyzes were performed using SPSS (Statistical Package for Social Sciences, version 20.0), with a confidence level 95% and p <0.05, using chi-square tests. Raised by the data, we found that EDA is a practical and safe exam, with very few complications, agitation and presence of food in the stomach the most common limitations. In general descriptive analysis it was observed that most of the exams was held in females, forming more than 70% of the total sample. The predominant age group, regardless of gender, was 41-60 years. The frequent pathologies in esophageal segment were Esophagitis. Gastric segment, the highest frequency of findings were Gastritis, which are more common with advancing age. Gastroduodenal in Transition, the Channel Pyloric ulcers are the most described findings, but also observed modest findings of duodenitis. In the duodenum, the main findings were duodenal ulcers, followed by duodenitis and signs of atrophy. Therefore, the EDA are more performed in females, but have a higher percentage of normal results, with the highest frequency of findings found in males. So after analyzing 10,311 EDA, it is possible to predict the most common findings EDA.

Ultrasound and endoscopic findings in dogs with lymphangiectasia / [Conclusões ultrassonográfica e endoscópica em cães com linfangiectasia ]

Lymphangiectasia is a heterogenous inflammatory bowel disease characterized by lymphatic vessel dilation, chronic diarrhea and protein loss such as serum albumin and globulin. The most common cause of lymphangiectasia is considered to be the congenital malformation of the lymphatics. The study was conducted between 2012-2015 on 76 dogs suffering from intestinal disorders and manifesting digestive symptoms such as diarrhea or weight loss. In order to assess the origin of disorder, physical examination, biochemistry profile, ultrasound and endoscopic examinations were performed. Ultrasound examination tried to assess the changes of intestines' echogenicity, changes in wall thickness, wall layering and presence of striations or / and speckles (hyperechoic structures along intestinal mucosal layer). Endoscopic examination findings included dilated lacteals (59.2%) and erythema (21.1%). Although increased friability was observed in 33 dogs, it was not considered in the study due to limitations represented by the evaluation of the endoscopic images only. The study proved that an extremely significant statistical correlation exists between the presence of speckles and dilated lacteals in dogs with lymphangiectasia (P<0.05). Up to now, there is no other study to make an association between the white spots observed in ultrasound examination and dilated lacteals revealed after endoscopy in dogs with intestinal lymphangiectasia.(AU)

A linfangiectasia é uma doença inflamatória intestinal heterogênea, caracterizada por dilatação dos vasos linfáticos, diarreia crônica e perda de proteínas, como albumina sérica e globulina. A causa mais comum de linfangiectasia é considerada a malformação congênita dos linfáticos. O presente estudo foi realizado entre 2012 e 2015, em 76 cães que sofrem de distúrbios intestinais e manifestam sintomas digestivos, como diarreia ou perda de peso. Para avaliar a origem do distúrbio, foram realizados exame físico, perfil bioquímico, ultrassonográfico e endoscópico. O exame ultrassonográfico tentou avaliar as alterações da ecogenicidade do intestino, as alterações na espessura da parede, a estratificação e a presença de estrias e / ou de manchas (estruturas hiperecoicas ao longo da camada mucosa intestinal). Os resultados do exame endoscópico incluíram lacteais dilatadas (59,2%) e eritema (21,1%). Embora tenha sido observada maior friabilidade em 33 cães, ela não foi considerada no estudo devido às limitações representadas pela avaliação apenas das imagens endoscópicas. O estudo demonstrou que existe uma correlação estatística extremamente significativa entre a presença de manchas e lacteais dilatadas em cães com linfangiectasia (P <0,05). Até o momento, não há outro estudo para associar as manchas brancas observadas no exame ultrassonográfico e lacteais dilatadas reveladas após endoscopia em cães com linfangiectasia intestinal.(AU)

Histórico familiar de câncer gástrico em pacientes dispépticos indicados à triagem endoscópica / Antecedentes familiares de cáncer gástrico en pacientes dispépticos derivados a triaje endoscópico / Family history of gastric cancer in dyspeptic patients referred for endoscopic screening

Resumo Objetivo Identificar o histórico familiar de primeiro grau de câncer gástrico em pacientes com sintomas dispépticos atendidos em um serviço público de endoscopia. Métodos Estudo transversal, realizado com pacientes dispépticos que tinham indicação para realizar o exame de endoscopia digestiva alta. A associação entre o histórico familiar de câncer gástrico e os resultados do exame endoscópico foi verificada por meio dos testes de Qui-quadrado ou Fisher, e medida seu efeito por meio da razão de chance e intervalo de confiança em analises uni e multivariadas. Utilizou-se regressão logística na análise dos dados. Resultados Observou-se que dos 751 pacientes dispépticos investigados, 44 (5,9%) possuíam histórico familiar de câncer gástrico, destes a maioria era do sexo feminino (70,5%), com idade maior ou igual a 45 anos (56,8%). Os pacientes com histórico familiar de câncer gástrico tinham maiores chances de não apresentarem diagnostico endoscópico de úlcera péptica (p=0,05; RC=2,33; IC=0,99-5,48). Além de maiores chances de alterações na mucosa gástrica (p=0,05; RC=1,06; IC=1,04-1,08) e infecção pela Helicobacter pylori (p=0,04; RC=1,79; IC=0,94-3,39) mesmo após ajustes nas análises. Conclusão A alteração endoscópica da mucosa gástrica e a infecção pela Helicobacter pylori em pacientes com sintomas dispépticos, mostraram associação independente com o histórico familiar de câncer gástrico. Diante disso, faz-se necessário a elaboração de protocolos de assistência à saúde para melhor investigação e vigilância dos familiares de câncer gástrico, bem como ações de educação em saúde para orientar os pacientes a respeito do rastreio e prevenção do câncer gástrico.

Resumen Objetivo Identificar los antecedentes familiares de primer grado de cáncer gástrico en pacientes con síntomas dispépticos atendidos en un servicio público de endoscopía. Métodos Estudio transversal llevado a cabo con pacientes dispépticos que habían sido derivados a realizar un estudio de endoscopía digestiva alta. La relación entre los antecedentes familiares de cáncer gástrico y los resultados del estudio endoscópico fue verificada mediante la prueba χ2 de Pearson o de Fisher, y su efecto fue medido a través de la razón de momios y del intervalo de confianza en análisis uni y multivariados. Se utilizó la regresión logística en el análisis de los datos. Resultados Se observó que de los 751 pacientes dispépticos investigados, 44 (5,9 %) tenían antecedentes familiares de cáncer gástrico, de los cuales la mayoría era de sexo femenino (70,5 %), de 45 años o más (56,8 %). Los pacientes con antecedentes familiares de cáncer gástrico tenían mayores chances de no presentar diagnóstico endoscópico de úlcera péptica (p=0,05; RC=2,33; IC=0,99-5,48). Además de mayores probabilidades de alteraciones en la mucosa gástrica (p=0,05; RC=1,06; IC=1,04-1,08) e infección por Helicobacter pylori (p=0,04; RC=1,79; IC=0,94-3,39), inclusive después de ajustes en los análisis. Conclusión La alteración endoscópica de la mucosa gástrica y la infección por Helicobacter pylori en pacientes con síntomas dispépticos mostraron relación independiente con los antecedentes familiares de cáncer gástrico.

Abstract Objective To identify first-degree relative history of gastric cancer in patients with dyspeptic symptoms receiving care at a public endoscopy service. Methods A cross-sectional study, performed with dyspeptic patients referred for an upper gastrointestinal endoscopy. The association between the family history of gastric cancer and the findings of the endoscopic examination was verified using the Chi-square or Fisher tests, and its effect was shown using odds ratio and confidence interval in univariate and multivariate analyses. Logistic regression was used to analyze the data. Results Among the 751 dyspeptic patients enrolled, 44 (5.9%) had a family history of gastric cancer, mostly females (70.5%) aged 45 years or older (56.8%). Patients with a family history of gastric cancer were more likely to have no endoscopic diagnosis of peptic ulcer (p=0.05; OR=2.33; CI=0.99-5.48). In addition, higher chances of gastric mucosal changes (p=0.05; RC=1.06; CI=1.04-1.08) and Helicobacter pylori infection (p=0.04; RC=1.79; CI=0.94-3.39) were found, even after adjusting the analyses. Conclusion The endoscopic gastric mucosal changes and Helicobacter pylori infection in patients with dyspeptic symptoms showed an independent association with family history of gastric cancer. Therefore, it is necessary to develop health care protocols for better investigation and surveillance of gastric cancer relatives, as well as health education actions to guide patients regarding screening and prevention of gastric cancer.

Bezoar gástrico, una aproximación al manejo / Gastric bezoar, an approach to medical management

The presence of bezoars in daily clinical practice is a event that poses a challenge both diagnostic, due to the associated factors in its development, as well as therapeutic. The management of this entity is associated with medical, endoscopic and surgical procedures and it is necessary to know its usefulness in different clinical scenarios. The role of carbonated beverages is increasingly accepted given its low cost, wide availability and high efficiency. For the aforementioned, it seems important to report a series of cases and the management performed.

La presencia de bezoares en la práctica clínica diaria es un evento que establece un desafío diagnóstico, por los factores asociados en su desarrollo, como también terapéutico. El manejo de esta patología se asocia a procedimientos médicos, endoscópicos y quirúrgicos siendo necesario conocer su utilidad en distintos escenarios clínicos. El rol de las bebidas carbonatadas es cada vez más aceptado dado su bajo costo, amplia disponibilidad y alta eficacia. Por lo antes señalado, nos parece importante reportar una serie de casos y el manejo realizado.

Relación del reflujo gastroesofágico y manifestaciones respiratorias, desde el punto de vista de la gastroenterología pediátrica / Relationship between gastroesophageal reflux and respiratory manifestations, from the pediatric gastroenterologist point of view

Gastroesophageal reflux is a frequent condition in the daily life of infants and older children. When reflux causes symptoms, it is called gastroesophageal reflux disease. Different extraesophageal symptoms have been frequently attributed to gastroesophageal reflux, however, new diagnostic techniques available, such as pHmetry with impedance measurement, have allowed us to evaluate and eventually dismiss such relationships. In this article we review the relationship between gastroesophageal reflux and laryngeal pathology, chronic cough, asthma and aspiration. In general terms, the empirical treatment of a presumed reflux is not recommended in asymptomatic patients, in whom its presence is not demonstrated by techniques such as pHmetry with impedance, given that therapeutic response is low and similar to placebo, with potential adverse effects.

El reflujo gastroesofágico es una condición frecuente en la vida diaria de lactantes y niños mayores. Cuando produce síntomas, se denomina enfermedad por reflujo gastroesofágico. Se ha atribuido frecuentemente diferentes síntomas extraesofágicos al reflujo, sin embargo, nuevas técnicas diagnósticas disponibles, como la pHmetría con medición de impedanciometría, han permitido evaluar y eventualmente descartar tales asociaciones. En este artículo se revisa la relación entre el reflujo gastroesofágico y patología laríngea, tos crónica, asma y aspiración. En términos generales, no se recomienda el tratamiento empírico de un supuesto reflujo en pacientes asintomáticos, en quienes tampoco esté demostrada su presencia por técnicas como la pHmetría con impedanciometría, dado que la respuesta terapéutica es baja y similar a placebo, con potenciales efectos adversos.

Intramural duodenal hematoma secondary to pancreatitis: case report and review of the literature

ABSTRACT CONTEXT: Spontaneous intramural duodenal hematoma is uncommon and is usually associated with coagulopathy, anticoagulant therapy and endoscopic procedures. The aim here was to describe a case of intramural duodenal hematoma caused by chronic exacerbation of pancreatitis. CASE REPORT: A 46-year-old male with chronic alcoholic pancreatitis was admitted to hospital due to abdominal pain, melena and low hemoglobin. An intramural duodenal hematoma with active bleeding was detected and selective angioembolization was warranted. The patient evolved with a perforated duodenum and underwent laparotomy with exclusion of the pylorus and Roux-en-Y gastrojejunostomy. He was discharged nine days later. CONCLUSION: Intramural duodenal hematoma is a rare complication of pancreatitis. Selective embolization is the preferred treatment for hemorrhagic complications of pancreatitis. However, the risk of visceral ischemia and perforation should be considered.

Doença ulcerosa péptica: realmente é possível identificá-la por meio das características da dor epigástrica? / Peptic ulcer disease: is it really possible to identify it through the characteristics of epigastric pain?

OBJETIVO: Determinar se características da dor epigástrica são capazes de identificar pacientes com doença ulcerosa péptica. MÉTODOS: Estudo caso-controle, com coleta de dados de setembro de 2014 a junho de 2016. Foram incluídos pacientes com mais de 18 anos com dispepsia que realizaram endoscopia digestiva alta ambulatorialmente. Os pacientes foram abordados antes de realizar a endoscopia digestiva alta, verificando, em suas guias, a presença de dispepsia, tendo sido convidados a responder um questionário, e, posteriormente, o prontuário de cada entrevistado foi avaliado para verificação do diagnóstico, sendo, então, divididos entre o Grupo Doença Ulcerosa Péptica (casos), com 32 pacientes, e o Grupo Controle, com 44 pacientes com dispepsia atribuída a outras causas. RESULTADOS: Dos pacientes com dispepsia não ulcerosa, 52,27% caracterizaram a dor como em queimação, sendo 47,72% moderada e que piorava com alimentação. Dentre os demais sintomas, 45,45% relataram náuseas e 25% desconforto pós-prandial, com 52,27% relatando histórico familiar negativo de doença ulcerosa péptica. Em contrapartida, dos pacientes com doença ulcerosa péptica, 53,12% referiram dor em queimação e de moderada intensidade, e 50% relataram piora com alimentação. Dentre os demais sintomas, prevaleceram também náuseas (53,12%) e desconforto pós-prandial (40,62%). A maioria (81,25%) relatou histórico familiar de doença ulcerosa péptica. Observou-se diferença estatística em dor noturna, predominando na doença ulcerosa péptica (p=0,0225) e dor em cólica na dispepsia não ulcerosa (p=0,0308), assim como na ausência de histórico familiar entre os pacientes com dispepsia não ulcerosa (p=0,0195). CONCLUSÃO: A dispepsia relacionada à doença ulcerosa péptica relaciona-se, principalmente, à piora noturna, sendo que a intensidade da dor, a relação com alimentação e os sintomas associados não auxiliaram na diferenciação da dispepsia não ulcerosa, diferentemente do que a literatura tradicionalmente informa.

To determine whether it is possible to identify Peptic Ulcer Disease through the characteristics of epigastric pain. METHODS: This is a case-control study with data collected between September 2014 and June 2016 including patients over 18 years of age with dyspepsia who underwent upper gastrointestinal endoscopy as outpatients. The patients were approached before the upper gastrointestinal endoscopy when their test requisition form indicated the presence of dyspepsia. The subjects were invited to answer a questionnaire and, afterwards, the records of all interviewees were evaluated to check for the diagnosis. Then, they were divided into a peptic ulcer disease group (cases), with 32 patients, and a control group, with 44 patients with dyspepsia from other causes. RESULTS: Among non-ulcer dyspepsia patients, 52.27% described the pain as a "burning pain", with 47.72% reporting it as moderate and aggravated by food intake. As for other symptoms, 45.45% of subjects reported nausea, and 25% reported postprandial discomfort; 52.27% had no family history of peptic ulcer disease. In contrast, 53.12% of peptic ulcer disease patients reported "burning" and moderate pain, and 50% said the pain was aggravated by eating. As for the other symptoms, nausea (53.12%) and postprandial discomfort (40.62%) prevailed; most of the patients (81.25%) had family history of peptic ulcer disease. There was a statistical difference in night pain, which was more prevalent in peptic ulcer disease (p=0.0225), and colicky pain, which was more frequent in nonulcer dyspepsia (p=0.0308), as well as absence of family history in non-ulcer dyspepsia patients (p=0.0195). CONCLUSION: Dyspepsia caused by peptic ulcer disease is mainly related to night worsening, and pain intensity, the relationship with food intake, and associated symptoms did not help differentiate nonulcer dyspepsia, differently from what the medical literature traditionally suggests.

Complicaciones de las videocolonoscopias en los primeros once años en un equipo quirúrgico / Adverse events related to colonoscopy on the initial eleven years of a surgical team

Antecedentes: la videocolonoscopia es un procedimiento imprescindible para el diagnóstico y tratamiento de afecciones colorrectales que forma parte de los recursos del cirujano. Posee un índice de complicaciones que pueden ser graves y requieren un adecuado manejo. Objetivo: analizar la experiencia de complicaciones de once años de un equipo quirúrgico realizando videocolonoscopia, con revisión de la bibliografía actual. Material y métodos: análisis retrospectivo consecutivo sobre una base de datos prospectiva. Entre enero de 2005 y diciembre de 2016 se realizaron endoscopias digestivas altas y bajas, diagnósticas y terapéuticas. Se analizan puntualmente las complicaciones de las videocolonoscopias y su manejo por parte del equipo quirúrgico. Resultados: de 3218 videocolonoscopias, 8 pacientes registraron complicaciones (0,2%). Todas fueron perforaciones colónicas resueltas mediante cirugía, con rafia primaria y operación tipo Hartmann. No hubo mortalidad en la serie. Conclusiones: si bien los procedimientos endoscópicos tienen efectos adversos, pueden ser llevados a cabo con estándares de calidad por cirujanos. Es importante que el equipo actuante esté capacitado para la resolución de complicaciones.

Complications associated with the procedure could be severe, and require an appropriate management. Objective: to analyze complications associated with colonoscopies done by a surgical team. Material and method: retrospective analysis on a prospective database. Diagnostic and therapeutic colonoscopies done by a surgical team between January 2005 and December 2016 were included. Complications and management strategies were analyzed. Results: of 3218 colonoscopies, 8 patients presented complications (0.2%). All were colon perforations solved by surgery, with primary closure and a kind of Hartmann's procedure. There was no mortality In this series. Conclusions: although endoscopic procedures may have adverse effects, they can be done under standards of quality by surgeons. It is important that the intervening team be qualified for the solution of complications.

Análise epidemiológica de pacientes submetidos à endoscopia digestiva alta em uma unidade de saúde de curta permanência / Epidemiological analysis of patients submitted to high digestive endoscopy in a short-stay health unit

Introdução e objetivos: a Endoscopia Digestiva Alta (EDA) representa o método de endoscopia mais usado, e geralmente é realizada sob sedação consciente. Dentre os efeitos adversos (EA) deste exame, os eventos cardiorrespiratórios são os que implicam maior importância, representando cerca de 60% do total, estando relacionados a fatores predisponentes dos pacientes, tais como obesidade, idade e doenças pulmonares prévias. Assim, considerando-se a relevância dos fatores de risco (FR) relacionados ao paciente e seus possíveis efeitos na morbimortalidade geral do procedimento, objetiva-se com o presente trabalho epidemiológico traçar o perfil do paciente que se submete à EDA no Brasil. Métodos: o estudo é transversal com amostragem aleatória de 974 pacientes submetidos à EDA eletiva. O questionário foi aplicado entre janeiro de 2013 e junho de 2013. Resultados: a média de idade foi de 40,88 anos, sendo 11,50% acima dos 60 anos. A média do IMC foi de 26,21kg/m², com 53,18% dos entrevistados apresentando sobrepeso ou obesidade. As morbidades encontradas incluíram hipertensão arterial sistêmica (N=152); outras doenças cardíacas (N=35); doenças respiratórias (N=599); diabetes mellitus (N=43); doença tireoidiana (N=68). Os principais medicamentos utilizados foram os benzodiazepínicos (4,93%) ou outros neuropsiquiátricos, somando 11,59%. O uso de álcool foi relatado por 37,39% e 5,54% eram tabagistas. Apenas 19,40% dos pacientes não apresentavam alguma enfermidade coexistente ou FR. Conclusão: considerando-se a endoscopia e a sedação envolvida, a atenção às variações demográficas e epidemiológicas populacionais assume especial importância, visto que estão diretamente relacionadas ao aumento da probabilidade de ocorrência de EA cardiorrespiratórios durante e após o procedimento. As conclusões deste trabalho devem ser entendidas à luz de seu local de realização, que é uma unidade ambulatorial.

Background: the Upper Gastrointestinal Endoscopy (UGE) represents the most common endoscopic modality and it is usually made with conscious sedation. Among the adverse events of this procedure, the cardiovascular events are the most relevant, comprising around 60% of overall events. It is known that some adverse events are related to patient's risk factors, such as obesity, age and pulmonary disease. Thus, considering the importance of risk factors and their impact in the morbimortality related to the procedure, the aim of this study is to know the epidemiological profile of the patients that need an endoscopy in Brazil. Methods: it is a sectional study with an aleatory sample of 974 patients that was submitted to an elective UGE in the period of January of 2013 and June of 2013. A questionnaire was applied to each individual. Results: the average age of the study was 40.88 years old, with 11.50% being over 60 years old. The body mass index (BMI) average was 26.21 kg/m² among which 53.18% of the interviewed could be classified as overweight or obese. The morbidities founded were high blood pressure (N=152); other cardiac diseases (N=35); respiratory diseases (N=599); diabetes mellitus (N=43); thyroid diseases (N=68). The most used drugs were benzodiazepines (4.93%) or other psychiatric drugs, comprising 11.59%. The use of alcohol was mentioned by 37.39% and 5.54% were smokers. Only 19.40% amongst the patients did not mention any comorbidity or risk factor to the procedure. Conclusion: considering the endoscopy and the sedation involved in the procedure, knowing the demographic and epidemiological differences between populations are of special importance, since they are related to the cardiorespiratory adverse events that can occur during and after an UGE. The conclusions of this study should be interpreted taking into account that it was made in an ambulatory unity.

Hallazgos histológicos de biopsia por endoscopia digestiva superior en el paciente pediatrico / Histological findings of biopsies obtained by upper gastrointestinal tract endoscopy in children

Antecedentes: El desarrollo de la endoscopia ha dado pasos agigantados en el campo de la gastroenterología pediátrica, convirtiéndose en una prueba diagnóstica de primera línea por la posibilidad de toma de biopsia, además se ha consolidado como un tratamiento eficaz en numerosas enfermedades digestivas. Objetivo: revisar los hallazgos histológicos de biopsias obtenidas por endoscopia digestiva superior en el paciente pediátrico del Hospital Nacional Dr. Mario Catarino Rivas (HNMCR) en el período comprendido entre enero a mayo 2016. Pacientes y métodos: Estudio transversal, descriptivo, realizado en pacientes con edades comprendidas entre 28 días y 18 años. Se revisaron 40 biopsias que cumplían los criterios de inclusión.

Resultados: se revisaron 40 biopsias, 55% hombres, 45% mujeres, el 47.5% de los pacientes eran adolescentes. La indica-ción mas común fue el dolor abdominal crónico (33%), seguido por la gastritis crónica (28%) y reflujo gastroesofágico (20%). Los hallazgo histopatológico más frecuente fueron la gastritis crónica 43%, esofagitis crónica 30% y el Helycobacter Pylori 13%. Conclusión: En el 95% de las biopsias realizadas se encontraron anormalidades, siendo el más frecuente la gastritis crónica...AU)

Mechanisms of growth inhibition of Phytomonas serpens by the alkaloids tomatine and tomatidine

Phytomonas serpens are flagellates in the family Trypanosomatidae that parasitise the tomato plant (Solanum lycopersicum L.), which results in fruits with low commercial value. The tomato glycoalkaloid tomatine and its aglycone tomatidine inhibit the growth of P. serpens in axenic cultures. Tomatine, like many other saponins, induces permeabilisation of the cell membrane and a loss of cell content, including the cytosolic enzyme pyruvate kinase. In contrast, tomatidine does not cause permeabilisation of membranes, but instead provokes morphological changes, including vacuolisation. Phytomonas treated with tomatidine show an increased accumulation of labelled neutral lipids (BODYPY-palmitic), a notable decrease in the amount of C24-alkylated sterols and an increase in zymosterol content. These results are consistent with the inhibition of 24-sterol methyltransferase (SMT), which is an important enzyme that is responsible for the methylation of sterols at the 24 position. We propose that the main target of tomatidine is the sterols biosynthetic pathway, specifically, inhibition of the 24-SMT. Altogether, the results obtained in the present paper suggest a more general effect of alkaloids in trypanosomatids, which opens potential therapeutic possibilities for the treatment of the diseases caused by these pathogens.

Análise dos achados endoscópicos mais comuns em pacientes com sintomas dispépticos / Analysis of common endoscopic findings in patients with dyspeptic symptoms

Introdução: dispepsia representa queixa comum na prática clínica diária. É um conjunto variável de sintomas como dor ou queimação epigástrica, saciedade precoce ou plenitude pós-prandial, de acordo com os Critérios Diagnósticos Roma III. Associações entre esses sintomas, idade, sexo e achados endoscópicos sugerem diferentes prevalências. Faltam pesquisas com bases científicas para sistematizar quais pacientes devem ser submetidos à endoscopia. Objetivo: descrever a prevalência dos achados endoscópicos e relacioná-los às características dos pacientes com sintomas dispépticos submetidos à Endoscopia Digestiva Alta (EDA). Métodos: Estudo transversal, descritivo e analítico, realizado no HGCR (Hospital Governador Celso Ramos) em Florianópolis - SC. Foram analisados 450 laudos endoscópicos de pacientes que apresentaram como indicação dispepsia e/ou sintomas dispépticos para a realização de EDA. Coletou-se dados acerca da indicação, sexo, idade e achados à endoscopia, que foram analisados pelo teste Qui-quadrado e Fisher no software SPSS18.0. Este trabalho foi aprovado pelo Comitê de Ética da Unisul (Universidade do Sul de Santa Catarina). Resultados: a maioria dos laudos do estudo apresentou alterações à EDA, sendo o principal achado a gastrite enantematosa e/ou erosiva. Do total, a maioria pertencia a mulheres entre 30 e 49 anos. Associações de idade até 30 anos e EDA normal, assim como pacientes acima de 70 anos e câncer gástrico, foram estatisticamente significantes.

Introduction: dyspepsia is a common complaint in daily clinical practice. It is a variable set of symptoms, such as epigastric pain or burning, early satiety or postprandial fullness, according to Rome III. Associations between these symptoms, age, gender and endoscopic findings suggest different prevalences. There are insufficient researches with scientific bases to systematize which patients should undergo upper endoscopy. Objective: to describe the prevalence of endoscopic findings and relate to the characteristics of patients with dyspeptic symptoms undergoing upper endoscopy. Methods: crosssectional, descriptive and analytical study was carried out in a Hospital in Florianópolis-SC. We analyzed 450 endoscopic reports with dyspepsia as an indication and/ or dyspeptic symptoms for the realization of upper endoscopy. Data were collected on the indication, such as age, gender and endoscopic findings, which were analyzed by chi-square and Fisher tests in software SPSS 18.0. This study was approved by the Ethics Committee of Unisul. Results: most of the reports of the study presented findings in the endoscopy, the main findings were enanthematous and/or erosive gastritis. Of the total, the majority belonged to women between 30 and 49 years old. Associations between 30 years old or less and normal endoscopy, as well as, patients over 70 years and gastric cancer were statistically significant. Conclusion: the prevalence of upper endoscopy with some found in dyspeptic patients was high. Enanthematous and/or erosive gastritis was the most prevalent finding. Most patients were female, mean age of patients 45 years and the main dyspeptic symptom was epigastric pain. Associations between age and findings can be made.

CHOLANGIOSCOPY IN BILE DUCT DISEASE: a case series / Colangioscopia nas afecções biliares: uma série de casos

Context Direct endoscopic visualization of biliopancreatic duct is certainly one of the greatest advances of therapeutic endoscopy. The use of a single-operator cholangioscopy platform (SpyGlass) is a promising technique in the evaluation of diseases such as indeterminate biliary stricture and giant choledocholitiasis. This is the first Brazilian case series using this technology. Methods We report a case series of 20 patients in whom SpyGlass was used with diagnostic and therapeutic intention. Results Most patients were female (60%) and the median age was 48 years (ranging from 14 to 94). Choledocholitiasis was the most common indication (12/20), and electrohydraulic lithotripsy was applied in eight (66%). Electrohydraulic lithotripsy was successful in seven (87.5%) patients. Partial stone fragmentation occurred in one patient with large stone causing stone-choledochal disproportion, which was conducted with biliary plastic stent placement and a second scheduled endoscopic approach in 3 months. In cases of undefined etiology of biliary strictures, it was possible to exclude malignancy due to direct visualization (7/8) or biopsy (1/8). One complication occurred (duodenal perforation) after papillary balloon dilation. Conclusion The use of SpyGlass demonstrated the benefits, especially in cases of large bile duct stones and indeterminate biliary strictures. Other potencial improvements such as reduction on radiation exposure should be confirmed in prospective studies. .

Contexto A visão endoscópica direta das vias biliopancreáticas é certamente um dos maiores avanços na endoscopia terapêutica. O uso da plataforma de colangioscopia de operador-único (SpyGlass) é uma técnica promissora na avaliação de afecções tais como estenoses de etiologia indefinida e coledocolitíase gigante. Essa é a primeira série de casos brasileira utilizando o método. Métodos Reportamos uma série de casos de 20 pacientes nos quais foi realizado Spyglass com objetivos diagnósticos e terapêuticos. Resultados A maioria dos pacientes era do sexo feminino (60%), com idade que variou de 14 a 94 anos (mediana de 48). Coledocolitíase foi a indicação mais comum (12/20) e litotripsia eletrohidráulica foi realizada em oito (66%). Litotripsia eletrohidráulica foi realizada com sucesso em sete (87,5%) pacientes. Fragmentação parcial dos cálculos ocorreu em um paciente com desproporção cálculo-coledociana, sendo conduzido com colocação de prótese plástica e reabordagem endoscópica programada em 3 meses. Nos casos de estenoses biliares de etiologia indeterminada, foi possível a exclusão de malignidade devido a visualização direta (7/8) ou biópsia (1/8). Uma complicação ocorreu (perfuração duodenal) após dilatação balonada da papila. Conclusão Foram demonstrados os benefícios do uso do Spyglass, principalmente nos casos de coledocolitíase gigante e estenoses biliares de etiologia indefinida. Outras potenciais vantagens como a redução da exposição à radiação deve ser confirmada em estudos prospectivos posteriores. .

Utilidad del índice de Rockall en pacientes con episodios de hemorragia digestiva alta no variceal / Utility of Rockall index in patients with upper non-variceal gastrointestinal bleeding episodes

INTRODUCCIÓN: por la alta mortalidad de pacientes con hemorragia digestiva alta, es necesario la utilización de sistemas pronósticos para el adecuado manejo de aquellos con alto riesgo de resangrar. OBJETIVO: evaluar la capacidad del índice de Rockall para predecir el riesgo de resangrado y mortalidad en el paciente con episodio de hemorragia digestiva alta de origen no variceal. MÉTODOS: estudio longitudinal, descriptivo y prospectivo entre diciembre de 2011 y junio de 2012. Se incluyeron 89 pacientes admitidos en el cuerpo de guardia del Hospital Militar Central "Dr. Carlos J. Finlay", con evidencia clínica de hemorragia digestiva alta, a quienes se les realizó una endoscopia dentro de las 24 h posteriores al ingreso. Se evaluaron parámetros demográficos (edad, género) y endoscópicos (hallazgos, terapéutica). Se aplicó el índice de Rockall y se evolucionó al paciente las 72 h siguientes al ingreso. Se realizó un análisis por curva de COR. RESULTADOS: hubo un predominio del sexo masculino (64/89; 71,9 %); la edad promedio fue de 63,6 años. El 26,0 % de los casos (n= 23) presentó un índice de Rockall alto, con una capacidad predictiva sobre la mortalidad (área bajo la curva de COR de 0,875) y el resangrado (área bajo la curva de COR de 0,757; p= 0,020). CONCLUSIONES: se confirma la utilidad del índice de Rockall para identificar a los pacientes con alto riesgo de fallecer y resangrar, lo que puede ser utilizado para el manejo del paciente con hemorragia digestiva no variceal.

INTRODUCTION: the use of prognostic systems is necessary for the proper management of those at high risk of bleeding again. OBJECTIVE: to evaluate the ability of the Rockall index for predicting the risk of rebleeding and mortality in patients with upper gastrointestinal bleeding episode of non-variceal origin. METHODS: a longitudinal, descriptive, prospective study was conducted in 89 patients who arrived with clinical evidence of upper gastrointestinal bleeding at ER of "Dr. Carlos J. Finlay" Central Military Hospital from December 2011 to June 2012. They underwent an endoscopy within 24 h after admission. Demographic parameters (age, gender) and endoscopic (findings, therapeutic) were evaluated. Rockall index was applied and patients were followed up 72 h after admission. COR curve Analysis was performed. RESULTS: there was a predominance of males (64/89, 71.91 %); the average age was 63.58 years. 26 % of cases (n= 23) had a higher rate of Rockall, with a predictive capacity for mortality (area under the ROC curve = 0.875) and rebleeding (area under the ROC curve = 0.757, p= 0.020). CONCLUSIONS: Rockall index utility is confirmed to identify patients at high risk of death and reindent, which can be used for the management of patients with non-variceal gastrointestinal bleeding.

Caracterización de los pacientes con hemorragia de vías digestivas altas no varicosa en un hospital de tercer nivel de Cundinamarca, Colombia / Characterization of patients with non-varicose upper GI bleeding at a Level 3 Hospital in Cundinamarca, Colombia

La hemorragia de vías digestivas altas (HVDA) es una emergencia habitual; su etiología más común es laúlcera péptica. La restauración del volumen intravascular y la presión arterial son la prioridad del manejo previo al identificar la causa del sangrado. La esofagogastroduodenoscopia (EGD) debe realizarse luego de lareanimación inicial, así como lograrse la estabilización hemodinámica, para identifi car la causa del sangradoy dar el tratamiento necesario. Se realiza un estudio sobre el evento en un hospital de referencia de tercernivel, en Cundinamarca, Colombia.Materiales y métodos: Estudio descriptivo retrospectivo; datos obtenidos de la historia clínica electrónica de pacientes adultos que consultaron por urgencias en el Hospital Universitario de la Samaritana (HUS) por HVDA, diagnosticada por hematemesis, melenas, rectorragia o anemia, y a quienes se les realizó EGDdurante el periodo abril de 2010-abril de 2011. Resultados: Se atendió a 385 pacientes a lo largo del período de estudio; se excluyó a 100 de ellos,debido a hemorragia secundaria a várices esofágicas, historia clínica incompleta y hemorragia digestivabaja, para un total de 285 pacientes analizados. Conclusiones: La mayoría de la población atendida en el Hospital Universitario de La Samaritana (HUS)por HVDA son adultos mayores de 60 años. La úlcera péptica sigue siendo el diagnóstico más común asociadoal uso de AINE y ASA. La mortalidad es comparable a la de las regencias internacionales.

Upper gastrointestinal tract bleeding is a common emergency whose most common etiology is a peptic ulcer.Restoration of intravascular volume and blood pressure management are priorities before identifyingthe cause of bleeding. After initial resuscitation and after hemodynamic stabilization has been achieved, anesophagogastroduodenoscopy (EGD) should be performed to identify the cause of bleeding and determinethe treatment needed. This is a study performed at a third level referral hospital in Cundinamarca, Colombia.Materials and Methods: This is a retrospective study of data from electronic medical records of adult patients admitted to the emergency room of the Hospital Universitario de la Samaritana (HUS) because of uppergastrointestinal tract bleeding which ahd been diagnosed because of hematemesis, melena, rectal bleedingand/or anemia. Patients all underwent EGD between April 2010 and April 2011.Results: 385 patients with upper gastrointestinal tract bleeding were seen during the study period, but 100were excluded because of bleeding secondary esophageal varices, incomplete clinical histories and lowergastrointestinal bleeding. A total of 285 patients were included. 69.1 % were older than 60 years, 73.3 % hadhypertension, 55.1 % reported use of infl ammatory drugs (NSAIDs) and aspirin (ASA), 19.6 % reported previous bleeding episodes, and 17.9 % had hemodynamic instability. 63 patients (22.1 %) required endoscopichemostasis, and 32 (11.2 %) experienced rebleeding. Overall mortality reported was 13.1 % of which 55.3 %were men. Mortality attributable to gastrointestinal bleeding was 3.1 %.Conclusions: The majority of patients served by the HUS with upper GI bleeding are adults over 60 years.Peptic ulcers remain the most common diagnosis associated with the use of NSAIDs and ASA. The mortalityrate is comparable to international standards.

Complications after intestinal resection in Crohn's disease: laparoscopic versus conventional approach / Complicações após ressecções intestinais na doença de Crohn: há diferenças entre as vias convencional e videolaparoscópica?

BACKGROUND: significant advances in medical therapy for Crohn's disease (CD) occurred in the last 12 years, mainly due to the introduction of anti-TNF therapy. Laparoscopic colorectal surgery represented the most important advance on surgical treatment in the management of CD, as it also had developed in the treatment of other conditions. There is a tendency for lower complication rates after laparoscopic bowel resections as compared to open surgery. The aim of this study was to analyze and compare the complication rates after bowel resections for CD between the two approaches in a Brazilian case series. METHODS: this was a retrospective longitudinal study, including CD patients submitted to bowel resections from a single Brazilian Inflammatory Bowel Diseases (IBD) referral center, treated between January 2008 and June 2012 with laparoscopic approach (LA) or conventional approach (CA). VARIABLES ANALYZED: age at surgery, gender, Montreal classification, smoking, concomitant medication, type of surgery, surgical approach, presence and type of complication up to 30 days after the procedures. Readmission and reoperation rates, as well as mortality, were also analyzed. Patients were allocated in two groups regarding the type of procedure (LA or CA), and complication rates and characteristics were compared. Statistical analysis was performed with Mann-Whitney test (quantitative variables) and chi-square test (qualitative variables), with p < 0.05 considered significant. RESULTS: a total of 46 patients (25 men) were included (16 submitted to LA), with mean age of 38.1 (± 12.7) years. The groups were considered homogeneous according to age, gender, CD location, perianal disease and concomitant medications. There were more patients with fistulizing CD on the CA group (p = 0.029). The most common procedure performed was ileocolic resection on both groups (56.7% of the CA and 75% of the LA patients - p = 0.566). Overall, total complications (surgical and medical, including minor and major issues) occurred in 60% (18/30) of the CA group and 12.5% (2/16) of the LA group (p = 0.002). Wound infection was the most frequent complication (10/30 on CA and 1/16 on the LA groups). There were 3 deaths in the CA group. Specific analysis of each complication did not demonstrate any difference between the groups regarding abdominal sepsis, urinary tract infections, pneumonia, readmission, reoperations and deaths (p = 0.074). CONCLUSIONS: there was a higher complication rate in patients operated with CA as compared to LA. This was probably due to patient selection for the laparoscopic approach, with severe cases, mostly due to fistulizing abdominal CD, being operated mainly by open surgery. LA tends to be the recommended approach in most cases of non-complicated CD. (AU)

INTRODUÇÃO: avanços significativos no tratamento medicamentoso da doença de Crohn (DC) ocorreram nos últimos 12 anos, principalmente após a introdução da terapia anti-TNF. A cirurgia laparoscópica colorretal representa um dos maiores progressos no tratamento cirúrgico minimamente invasivo da DC, bem como no manejo de outras afecções. Existe uma tendência a menores taxas de complicações com as ressecções intestinais laparoscópicas quando comparadas a cirurgia convencional. O objetivo deste estudo foi analisar e comparar as taxas de complicações após ressecções intestinais na DC entre as duas vias de acesso em uma série de casos brasileira. MÉTODO: estudo retrospectivo longitudinal, incluindo pacientes com DC submetidos a ressecções intestinais em um centro de referência brasileiro em doença inflamatória intestinal (DII), tratados entre janeiro de 2008 e junho de 2012, com cirurgia laparoscópica (CL) ou cirurgia convencional (CC). As variáveis analisadas foram: idade no momento da cirurgia, gênero, classificação de Montreal, tabagismo, medicações concomitantes, tipo de cirurgia, via de acesso, presença e tipo de complicação em até 30 dias do procedimento. Readmissão, reoperações e mortalidade também foram avaliadas. Os pacientes foram alocados em dois grupos de acordo com a via de acesso (CL ou CC), sendo as taxas de complicações comparadas entre si. Análise estatística foi realizada pelos testes de Mann-Whitney (variáveis quantitativas) e chi-quadrado (qualitativas), com p<0.05 considerado significativo. RESULTADOS: No total, 46 pacientes (25 homens) foram incluídos (16 operados por CL), com média de idade de 38,1 (± 12,7) anos. Os grupos foram considerados homogêneos em relação à idade, gênero, localização da doença, DC perianal e medicações concomitantes. Houve predomínio da forma fistulizante no grupo de cirurgias abertas (p = 0.029). O procedimento mais realizado foi a ileocolectomia direita em ambos os grupos (56,7% na CC e 75% na CL - p = 0.566). No total, complicações pós-operatórias (cirúrgicas e clínicas) ocorreram em 60% (18/30) dos casos após CC e 12,5% (2/16) após a CL (p = 0.002). Infecção da ferida operatória foi a complicação mais frequente (10/30 na CC e 1/16 na CL). Ocorreram 3 óbitos no grupo da CC. Em análise individualizada das complicações, não houve diferença entre os grupos em relação a sepse abdominal, infecções urinárias, pneumonia, reinternações, reoperações e óbitos (p=0.074). CONCLUSÕES: houve maior taxa de complicações nos pacientes operados por CC comparado a CL. A seleção de casos para cirurgia laparoscópica provavelmente contribuiu para este resultado, havendo uma tendência a utilização da cirurgia convencional nos casos mais graves, geralmente com DC abdominal fistulizante. A CL parece ser a via de acesso recomendada na maioria dos casos de DC não-complicada. (AU)

Manejo endoscópico de las complicaciones de la pancreatitis / Endoscopic management of the complications of pancreatitis

Tanto la pancreatitis aguda como crónica causan diferentes complicaciones que antes del advenimiento de la terapéutica endoscópica tenían que ser tratadas con cirugía convencional. El avance de la endoscopía intervencionista nos ha permitido acceder al páncreas y tratar estas complicaciones efectivamente y con menor morbilidad para nuestros pacientes. Aproximadamente el 90% de las pancreatitis aguda son edematosas, tienen una resolución clínica temprana y sin complicaciones. Los pacientes que son admitidos con pancreatitis necrotizante están predispuestos a tener diferentes tipos de complicaciones tanto locales como sistémicas particularmente si hay falla orgánica. Por otro lado la pancreatitis crónica es un proceso inflamatorio crónico del páncreas en donde se ha establecido la fibrosis de la glándula con posible disfunción exocrina y/o endocrina. El objetivo principal de la terapéutica endoscópica en la pancreatitis crónica es aliviar la obstrucción y disminuir la presión del conducto pancreático con la intención de aliviar el dolor abdominal. En esta revisión vamos a hablar acerca de las indicaciones y técnica endoscópica para tratar las diferentes complicaciones de la pancreatitis como, drenaje de pseudoquistes, necrosectomía pancreática, manejo del síndrome de conducto desconectado y terapia endoscópica en pancreatitis crónica.

Acute and chronic pancreatitis may lead to complications that prior the recent advancement of therapeutic endoscopy had to be treated with conventional surgery. The current techniques in interventional endoscopy allow us to access the pancreas and treat some of the complications in a minimally invasive way leading to less morbidity in our patients. Approximately 90% of acute pancreatitis episodes are edematous with early resolution of clinical symptoms and rarely leading to major complications. Patients with necrotizing pancreatitis are susceptible to local and systemic complications particularly in the setting of organ failure. On the other hand chronic pancreatitis is as a chronic inflammatory process that leads to fibrosis of the gland and in occasions to exocrine and/or endocrine insufficiency. The main objective of therapeutic endoscopy in chronic pancreatitis is to relief the obstruction and decreases the pressure in the pancreatic duct with the intention to alleviate abdominal pain. In this review we will address the indications and endoscopic techniques to treat the different complications of pancreatitis such as pseudo cyst drainage, walled off necrosis debridement, disconnected duct syndrome and different options for endoscopic therapy in chronic pancreatitis.

Esofagitis eosinofílica en adultos, una entidad clínico-patológica emergente / Eosinophilic esophagitis in adults, an emerging clinicopathological entity

Background: Eosinophilic esophagitis (EE) is a clinicopathologic primary disease of the esophagus, characterized by dense eosinophilic infiltration and it is currently identified as an emerging global entity capable of producing dysphagia and food impaction in adults. Objective: Review of the literature and analysis of the current evidence related to eosinophilic esophagitis in adults. Methods: An electronic search was performed in PubMed to identify relevant literature regarding epidemiology, pathogenesis, clinical presentation, diagnosis, treatment and prognosis of EE. The MeSH terms: 'Eosinophilic esophagitis' AND 'adults', were used including studies from 1975 to 2012, in English and Spanish written papers. Results: A total of 467 articles were identified in PubMed, where 374 correspond to adults. Eighty percent of the papers were published during the last six years, being mostly case reports or series. Although the pathogenesis is unknown, our review suggests a multifactorial cause, with an altered immune response and genetic component associated to it. At the same time, it was found that adult patients often have a long history of intermittent dysphagia or food impaction. Currently, there is no established consensus for histological diagnosis; however, eosinophilic infiltration of 15 per high power field is accepted. The most commonly used treatment in adults is topical corticosteroids. Although EE is a chronic disease, it does not seem to have a significant impact on morbimortality. Conclusions: Eosinophilic esophagitis is a chronic inflammatory disease with immunoallergic compromise, which requires clinical and histological diagnosis. A multidisciplinary approach to understand its natural history is suggested, thus developing future therapeutic approaches.

Introducción: La esofagitis eosinofílica (EE) es una enfermedad clínico-patológica primaria del esófago, caracterizada por infiltración eosinofílica densa y actualmente identificada como una entidad emergente a nivel mundial, capaz de producir disfagia e impactación alimentaria en adultos. Objetivo: Revisión de la literatura y análisis de la evidencia actual de EE en el adulto. Metodología: Se realizó una búsqueda electrónica en PubMed para identificar literatura relevante sobre epidemiología, patogenia, presentación clínica,diagnóstico, tratamiento y pronóstico. Se utilizaron los términos MeSH: 'Eosinophilic esophagitis' AND 'adults', incluyendo estudios publicados desde 1975 a 2012, en idiomas inglés y español. Resultados: Un total de 467 artículos se identificaron en PubMed, donde 374 corresponden a adultos. Durante los últimos seis años se publicó el 80 por ciento de ellos, siendo en su mayoría informes de casos o series de casos. Aunque la patogenia es desconocida, la presente revisión sugiere que es multifactorial, con alteración de la respuesta inmune y componente genético. Se encontró que los pacientes adultos presentan frecuentemente una larga historia de disfagia o impactación alimentaria. Actualmente, no existe un consenso establecido para el diagnóstico histológico, sin embargo, la infiltración eosinofílica de 15/campo de gran aumento es aceptada. El tratamiento más comúnmente indicado en adultos son los corticoesteroides tópicos. Aunque la EE es una patología crónica, no parece impactar significativamente la morbimortalidad. Conclusiones: La EE es una enfermedad inflamatoria crónica con compromiso inmunoalérgico, que requiere un diagnóstico clínico e histológico. Se sugiere un enfoque multidisciplinario con el fin de comprender su historia natural, desarrollando así futuros enfoques terapéuticos.
