ABSTRACT Introduction: the infection for Helicobacter pylori is one of the more prevalent in the world; it supposes a significant burden for the sanitary systems, due to the high resistance to antibiotics that it presents for its eradication. Objective: to determine the clinical epidemiological characteristics of the infection due to Helicobacter pylori in patients treated in the provincial consultation of Gastroenterología. Materials and methods: an observational, descriptive study was carried out in a universe formed by 167 patients with positive Helicobacter pylori determined by urease test. The variables to consider were age, sex, histologic diagnosis, clinical symptoms and clinical evolution after the specific treatment for Helicobacter pylori. The statistical technique of analysis of frequencies distribution was used. Results: 59, 6% of the patients was Helicobacter pylori positive with prevalence of the male sex; chronic gastritis was the gastric alteration more associated to the infection. Epigastralgia and abdominal distension were the most frequent symptoms. 49% of the cases evolved in a satisfactory way and only 17% answered bad to the treatment. Conclusions: a high percent of infection by Helicobacter pylori was found and also a good answer to the used treatment (AU).

Gastric outlet obstruction as manifestation of eosinophilic gastroenteritis / Obstrucción gástrica como manifestación de gastroenteritis eosinofílica

RESUMEN La gastroenteritis eosinofílica (EG) es una entidad poco frecuente. Presentamos un varón de 55 años sin antecedentes de atopía ni alergia, que presentó dolor abdominal y vómitos. La tomografía computarizada abdominal y la ecoendoscopia demostraron engrosamiento de la pared gástrica con engrosamiento de la pared del duodeno superior, sin masa definida ni colección de líquido. La endoscopia gastrointestinal confirmó engrosamiento de pliegues prepilóricos y duodeno superior con estenosis luminal. Se realizó gastrectomía parcial por ausencia de diagnóstico definitivo y sospecha de posible malignidad y diagnóstico de obstrucción de la salida gástrica. La histopatología fue compatible con EG, tratada con un tratamiento con corticoides de 8 semanas de duración, mostró mejoría clínica, aumento de peso y normalización del recuento de eosinófilos en sangre periférica.

ABSTRACT Eosinophilic gastroenteritis (EG) is a rare entity. We report a 55-year-old man had no previous atopy or allergic history, who presented abdominal pain and vomiting. Abdominal computed tomography and endoscopy ultrasonography demostrated gastric wall thickening with wall thickening of the superior duodenum, without defined mass or fluid collection. Gastrointestinal endoscopy confirmed thickening of prepyloric folds and superior duodenum with luminal stenosis. Parcial gastrectomy was performed due to absence of definitive diagnosis and suspicion of possible malignancy and diagnosis of gastric outlet obstruction. Histopathology was compatible with EG, treated with an 8-week long corticosteroid therapy, showed clinical improvement, weight gain and normalization of eosinophil count on peripheral blood.

Caracterización de la infección por Helicobacter pylori en niños y adolescentes en un servicio ambulatorio / Characterization of Helicobacter pylori infection in children and adolescents in an ambulatory service

Introducción: la infección por Helicobacter pylori es muy común, particularmente en los países en vías de desarrollo, y juega un rol importante en la enfermedad ácido péptica. Objetivos: conocer la prevalencia y algunos datos clínico epidemiológicos, describir los hallazgos endoscópicos (gastritis eritematosa, nodular y úlcera duodenal), y relacionarlos con los hallazgos histológicos; describir la asociación entre los grados histológicos de la gastritis crónica y la positividad de la prueba de ureasa rápida y la presencia de Helicobacter pylori según histología, así como identificar la relación de los pacientes con gastritis crónica antral y úlcera duodenal por Hp, con la edad. Métodos: se realizó un estudio tipo descriptivo prospectivo durante 3 años se hizo una encuesta de síntomas a pacientes y/o padres y examen físico. Se realizó panendoscopia, previo consentimiento informado, y 2 biopsias de mucosa antral para prueba de ureasa rápida, así como estudio histopatológico (hematoxilina-eosina y Giemsa) para determinar el grado de gastritis y presencia de Helicobacter pylori según sistema Sydney. Se demostró la infección por uno de los métodos. Resultados: se seleccionaron 196 pacientes entre 7-18 años (media 14,6) de 471 (41,6 por ciento). El 53 por ciento era del sexo femenino, y el 59,7 por ciento tenía entre 10 y 14 años. Por endoscopia, el 49,5 por ciento tenía gastritis eritematosa antral, el 36,8 por ciento gastritis nodular astral, y el 13,7 por ciento úlcera duodenal con gastritis asociada. Con antecedentes familiares de úlcera péptica estuvo el 29,6 por ciento, con epigastralgia el 85,2 por ciento, con acidez el 46,4 por ciento con vómitos el 21 por ciento y con náuseas el 16,3 por ciento. En relación con el tiempo de evolución al diagnóstico, predominó el grupo de más de un año (24,5 por ciento), seguido del de 4-6 meses (22,4 por ciento). Todos presentaron gastritis crónica de diferentes grados: ligera (34,7 por ciento), moderada (37,2 por ciento) y severa (28,1 por ciento), con Helicobacter pylori por ureasa rápida 83,2 por ciento y 93,4 por ciento por histología, con coincidencia de ambos métodos en 150 (76,5 por ciento). Se observó presencia de nódulos linfoides en 41,8 por ciento. Conclusiones: la infección por Helicobacter pylori es frecuente en niños y adolescentes, causa lesiones inflamatorias gastroduodenales, en particular, gastritis nodular antral. Se encuentra una asociación importante del Helicobacter pylori por ambos métodos diagnósticos. Se recomienda seguimiento por biopsia, en especial, a los que continúan con infección crónica y presenten nódulos linfoides, por el riesgo de presentar linfoma gástrico de células B del tejido linfoide asociado a mucosa (linfoma MALT), si no se consigue la erradicación del Helicobacter pylori(AU)

Introduction: Helicobacter pylori infection is very common, particularly in developing countries, and plays an important role in acid peptic disease. Objectives: to know the prevalence and some clinical epidemiological data for describing the endoscopic findings (erythematous gastritis, nodular and duodenal ulcer), and to relate them with the histological findings; to describe the association among the histological degrees of chronic gastritis and the positivity of the rapid urease test, and the presence of Helicobacter pylori according to histology, as well as identifying by Hp with age the number of patients with chronic antral gastritis and duodenal ulcer. Methods: a prospective, descriptive study was carried out during 3 years, and a survey of symptoms was made to patients and / or parents and also physical examination. Panendoscopy was performed with prior informed consent, and also 2 antral mucosa biopsies for rapid urease test, as well as histopathological study (hematoxylin-eosin and Giemsa) to determine the degree of gastritis and the presence of Helicobacter pylori according to the Sydney system. Infection was demonstrated by one of the methods. Results: 196 patients among 7-18 years (mean 14.6) were selected of 471 (41.6 percent). 53 percent were female, and 59.7 percent were among 10 and 14 years old. By endoscopy, 49.5 percent had antral erythematous gastritis, 36.8 percent astral nodular gastritis, and 13.7 percent duodenal ulcer with associated gastritis. 29.6 percent had a family history of peptic ulcer, 85.2 percent of epigastralgia, 46.4 percent with acidity, 21 percent with vomiting, and 16.3 percent with nausea. In relation to the time of evolution to the diagnosis, the group of more than one year prevailed (24.5 percent followed by the one of 4-6 months (22.4 percent). All presented chronic gastritis of different degrees: light (34.7 percent), moderate (37.2 percent) and severe (28.1 percent), with Helicobacter pylori by rapid urease 83.2 percent, and 93.4 percent by histology with coincidence of both methods in 150 (76.5 percent). The presence of lymphoid nodules was observed in 41.8 percent. Conclusions: Helicobacter pylori infection is frequent in children and adolescents causing gastroduodenal inflammatory lesions, in particular antral nodular gastritis. An important association of Helicobacter pylori is found by both diagnostic methods. Follow-up by biopsy is recommended, especially those who continue with chronic infection and have lymphoid nodules due to the risk of presenting B-cell gastric lymphoma of the lymphoid tissue associated to the mucosa (MALT lymphoma), if Helicobacter pylori eradication is not achieved(AU)

Systemic diseases and other painful conditions in patients with temporomandibular disorders and migraine

Abstract Temporomandibular disorders (TMD) are a highly prevalent, painful musculoskeletal condition affecting the masticatory system, and are frequently associated with migraines (M) and other diseases. This study aimed to investigate the association between painful TMD and M with other painful conditions and systemic diseases, such as cervicalgia, body pain (BP), ear-nose-throat disorders, musculoskeletal disorders, diabetes, cardiopulmonary diseases and gastritis/peptic ulcer. Methods: This was a cross-sectional study conducted in a sample of 352 individuals. Participants were stratified into three groups according to the presence of painful TMD and M: controls [individuals free of TMD and any headache (HA)]; TMD only (presence of painful TMD, but free of any HA); and TMD+M (presence of painful TMD and M). TMD was classified according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) - Axis I. Nonspecific physical symptoms (NSPS) were assessed by RDC/TMD - Axis II. The International Classification of Headache Disorders - II criteria, second edition, were applied to identify and classify primary HA. Other painful conditions and systemic diseases were assessed by volunteers' self-report. The prevalence of all assessed conditions was higher in the TMD+M group. Multiple regression models showed that cervicalgia was associated with the TMD only group (p<0.05), whereas gender (p<0.05), cervicalgia (p<0.05), BP (p<0.05) and NSPS (p<0.05) were significantly associated with the TMD+M group. Our results suggest that individuals with a comorbidity (TMD associated with M) have a more severe condition than those presenting only painful TMD.

Emphysematous Gastritis with Concomitant Portal Venous Air / 대한소화기학회지

Emphysematous gastritis is a rare form of gastritis caused by infection of the stomach wall by gas forming bacteria. It is a very rare condition that carries a high mortality rate. Portal venous gas shadow represents elevation of intestinal luminal pressure which manifests as emphysematous gastritis or gastric emphysema. Literature reviews show that the mortality rate is especially high when portal venous gas shadow is present on CT scan. Until recently, the treatment of emphysematous gastritis has been immediate surgical intervention. However, there is a recent trend of avoiding surgery because of the frequent occurrence of post-operative complications such as anastomosis leakage. In addition, aggressive surgical treatment has failed to show significant improvement in prognosis. Recently, the authors experienced a case of emphysematous gastritis accompanied by portal venous gas which was treated successfully by conservative treatment without immediate surgical intervention. Herein, we present a case of emphysematous gastritis with concomitant portal venous air along with literature review.

Histological and endoscopic features of the stomachs of patients with Chagas disease in the era of Helicobacter pylori

Introduction Most studies that have evaluated the stomachs of patients with Chagas disease were performed before the discovery of Helicobacter pylori and used no control groups. This study compared the gastric features of chagasic and non-chagasic patients and assessed whether gastritis could be associated with Chagas disease. Methods Gastric biopsy samples were taken from patients who underwent endoscopy for histological analysis according to the Updated Sydney System. H. pylori infection was assessed by histology, 16S ribosomal ribonucleic acid (rRNA) polymerase chain reaction (PCR), serology and the 13C-urea breath test. Patients were considered H. pylori-negative when all of these diagnostic tests were negative. Clinical and socio-demographic data were obtained by reviewing medical records and using a questionnaire. Results The prevalence of H. pylori infection (70.3% versus 71.7%) and chronic gastritis (92.2% versus 85%) was similar in the chagasic and non-chagasic groups, respectively; such as peptic ulcer, atrophy and intestinal metaplasia. Gastritis was associated with H. pylori infection independent of Chagas disease in a log-binomial regression model. However, the chagasic H. pylori-negative patients showed a significantly higher grade of mononuclear (in the corpus) and polymorphonuclear ...

Eosinophilic Gastroenteritis Presenting as Small Bowel Obstruction.

Eosinophilic gastroenteritis is a rare disease of unknown etiology characterized by eosinophilic infiltration of bowel wall to a variable depth. A 38 year old female presented with loose stool and vomiting since 3 days. She gave history of pain abdomen and weight loss since six months. Barium study revealed ascending colon stricture just proximal to the hepatic flexure ? malignant. A colonic biopsy was done, which was reported as edematous colonic mucosa with mild increase in eosinophils. Intra-operatively, a dense long segment stricture was found in the ascending colon extending to the caecum which warranted a right hemicolectomy. Histopathology revealed dense infiltration of eosinophils in the entire thickness of ileal and caecal wall. The diagnosis of eosinophilic gastroenteritis was made. Patient responded well to steroids. The case is being reported to highlight its rarity due to caecal involvement, presentation as intestinal obstruction and missed diagnosis on endoscopic biopsy.

Metagenomic analysis of the gastric microbiota cultivable from a patient with gastritis concomitant with Barrett´s esophagus / Análisis metagenómico de la microbiota gástrica cultivable a partir de un paciente con gastritis concomitante con esófago de Barrett

Barrett’s esophagus is a distal metaplasia characterized by the transformation of squamous mucosa into columnar mucosa. This esophageal phenotype is a product not only of the chronic reflux of gastric acids, but also by microorganisms that colonize the oral cavity and stomach. Two classes of microbiota can be identified in Barrett’s esophagus; microbiota type I is associated with the normal esophagus and type II with an inflamed esophagus. The present study describes the gastric microbiota of a patient with antral gastritis concomitant with Barrett’s esophagus absent infection with Helicobacter pylori. Gastric biopsies were obtained following the protocol of Sydney and following ethical practices. The isolates were cultivated under microaerophilic conditions on Columbia Agar supplemented with IsoVitaleX™ and 7% sterile blood. Extracted DNA was sequenced using 454-GS and the results analyzed on the MG-RAST server. Gram negative isolates were found and bacteria resistant to levofloxacin, amoxicillin, tetracycline, erythromycin, and clarithromycin. The phyla Bacteroidetes, Firmicutes, Fusobacteria and Proteobacteria, the genus Bacteroides and the species group Bacteroides fragilis were most abundant. Functionally, the metabolism of carbohydrates, amino acids, and to a lesser extent, the metabolism of cofactors and vitamins were most dominant, and of which the enzymes β-glucosidase (EC 3.2.1.21), β-galactosidase (EC 3.2.1.23) and β-N-acetylhexosaminidase (EC 3.2.1.52) were most dominant. The findings of this study, because they are of only one case may probably suggest a possible pathogenic role, previously undescribed for Bacteroides fragilis, associated with human gastritis when concomitant esophageal pathology exists.

El esófago de Barrett es una metaplasia distal caracterizada por la transformación de la mucosa escamosa a mucosa columnar. Este fenotipo esofágico es producto no solo de la exposición crónica al reflujo de ácidos gástricos sino también a microbios colonizantes de la cavidad oral y del estómago. El esófago Barrett presenta 2 clases de microbiotas; la microbiota tipo I asociada con esófago normal y la tipo II a fenotipos esofágicos inflamatorios. En el presente estudio se describió la microbiota gástrica de una paciente con gastritis antral concomitante con esófago de Barrett sin infección por Helicobacter pylori y se obtuvieron biopsias gástricas siguiendo el protocolo de Sydney y estándares bioéticos. Los cultivos se hicieron en condiciones microaerofílicas en agar Columbia suplementados con isovitalex y sangre estéril al 7%. El ADN extraído fue sometido a secuenciación empleando 454 GS y las lecturas fueron analizadas en el servidor MG-RAST. Se obtuvieron aislamientos gram-negativos y resistentes a levofloxacina, amoxicilina, tetraciclina, eritromicina y claritromicina. Los Phylum Bacteroidetes, Firmicutes, Fusobacteria y Proteobacteria, el género Bacteroides y las especies de grupo Bacteroides fragilis fueron los más abundantes. Funcionalmente, el metabolismo de carbohidratos, aminoácidos y en menor grado el metabolismo de cofactores y vitaminas fueron los más dominantes; de los cuales las enzimas la β-glicosidasa (EC 3.2.1.21), β-galactosidasa (EC 3.2.1.23) y la β-N-acetilhexosaminidasa (EC 3.2.1.52) fueron las más dominantes. Estos resultados, por ser de un solo caso, solo podrían sugerir un posible papel patogénico no descrito para Bacterioides fragilis asociado con gastritis humana cuando existe patología esofágica concomitante.

A Patient with Eosinophilic Gastroenteritis Presenting with Acute Pancreatitis and Ascites

Eosinophilic gastroenteritis (EGE) is a rare disease characterized by focal or diffuse eosinophilic infiltration of the gastrointestinal tract, especially the stomach and duodenum. EGE has vague, nonspecific symptoms, including nausea, vomiting, abdominal pain, diarrhea, weight loss, ascites, and malabsorption. Here, we report a patient with EGE presenting with concurrent acute pancreatitis and ascites. A 68-year-old woman was admitted with abdominal pain, nausea, vomiting, and watery diarrhea. Laboratory findings revealed elevated serum titers of amylase, lipase, and peripheral blood eosinophil count. An abdominopelvic computed tomography scan showed a normal pancreas, moderate amount of ascites, and duodenal thickening. A esophagogastroduodenoscopy showed patchy erythematous mucosal lesions in the 2nd portion of the duodenum. Biopsies from the duodenum indicated eosinophilic infiltration in the lamina propria. The patient was successfully treated with prednisolone and montelukast. Despite its unusual occurrence, EGE may be considered in the differential diagnosis of unexplained acute pancreatitis, especially in a patient with duodenal edema on imaging or peripheral eosinophilia.

Proteomics Analysis for Helicobacter pylori-infected Gastric Mucosa / 대한소화기학회지

BACKGROUND/AIMS: Helicobacter pylori infection is linked to the development of gastric cancer. H. pylori-associated gastric inflammation is considered to be the first important step in the histogenesis of such neoplasia. However, studies that compare proteome of gastric mucosa infected with or without H. pylori are lacking. METHODS: We employed proteomics analysis on the endoscopic biopsy specimens of gastric mucosa obtained from two groups (30 cases): healthy subjects without H. pylori infection (15 cases), and gastritis patients with H. pylori infection (15 cases). The pooled proteins obtained from gastric mucosa infected with or without H. pylori were separated by two-dimensional gel electrophoresis and analyzed by a computer-aided program. The altered protein expressions were then identified by mass spectrometry and validated by Western blotting and immunohistochemistry. RESULTS: On mass spectrometry using MALDI TOF(TM) Analyzer, the up-regulation of Keratin 1, ezrin, adenosine triphosphate (ATP) synthase subunit alpha mitochondrial isoform c, Keratin type I cytoskeletal 19, and Keratin type I cytoskeletal 9 were identified; in contrast, 71 kd heat shock cognate protein, ATP synthase subunit alpha mitochondrial precursor, and annexin IV were down-regulated. Among them, membrane cytoskeleton linker ezrin was validated using Western blot and immunohistochemistry. CONCLUSIONS: Expression of ezrin was significantly different between the gastric mucosa with and without H. pylori infection. Therefore, ezrin could be considered a promising potential molecular marker for detecting H. pylori infection in gastric mucosa.

Helicobacter pylori eradication does not influence gastroesophageal reflux disease: a prospective, parallel, randomized, open-label, controlled trial / Erradicação do Helicobacter pylori não influencia a doença do refluxo gastroesofágico: estudo prospectivo, paralelo, randomizado, aberto e controlado

CONTEXT: Helicobacter pylori has been associated with worsening of gastroesophageal reflux disease (GERD). OBJECTIVE: To evaluate the effect of H. pylori eradication in GERD patients. METHODS: We conducted a prospective, randomized, controlled trial performing symptom evaluation, endoscopy, histology, manometry and esophageal pH testing on GERD patients. Patients infected with H. pylori were randomized to: 1) eradication treatment plus proton pump inhibitors treatment, or 2) proton pump inhibitors alone. Patients not infected constituted a negative control group. After 3 months, patients were re-evaluated by symptom assessment, endoscopy, histology and manometry. RESULTS: GERD treatment resulted in significantly higher lower esophageal sphincter pressure, as measured by mean expiratory pressure, in H. pylori negative patients. There was significantly lower proportion of hypotensive waves and significantly higher proportion of normotensive waves in non-eradicated patients. All symptom scores were significantly reduced in the post-treatment period compared to baseline, to values that were similar among the three groups, in the post-treatment period. In the post-treatment period, erosive esophagitis was significantly less frequent on those not eradicated. CONCLUSION: Manometric, clinical and endoscopic data showed no benefit in eradicating H. pylori in GERD. Our data supports the hypothesis that H. pylori eradication does not influence GERD.

CONTEXTO: Existem trabalhos associando a erradicação do Helicobacter pylori à piora da doença do refluxo gastroesofágico (DRGE). OBJETIVO: Avaliar o efeito da erradicação do H. pylori em pacientes com DRGE. MÉTODOS: Estudo prospectivo, randomizado, controlado em que se avaliaram clínica, endoscopia digestiva alta, histologia, manometria e pHmetria de pacientes com DRGE. Pacientes infectados pelo H. pylori foram randomizados para: 1) erradicação da infecção seguida de tratamento com inibidor de bomba protônica, ou 2) tratamento com inibidor de bomba protônica apenas. Os não-infectados constituíram grupo-controle negativo. Após 3 meses, os pacientes foram reavaliados. RESULTADOS: A pressão do esfíncter inferior do esôfago, medida pela pressão expiratória máxima, foi significativamente maior em pacientes H. pylori negativos. Houve redução significativa na proporção de ondas hipotensivas e aumento significativo na proporção de ondas normotensivas nos pacientes que permaneceram Helicobacter pylori positivos. Todos os escores de sintomas foram reduzidos significativamente em comparação ao período inicial, para valores semelhantes, entre os três grupos, no pós-tratamento. Esofagite erosiva foi significativamente menos frequente no período pós-tratamento no grupo não-erradicado. CONCLUSÃO: Os achados manométricos, clínicos e endoscópicos não mostram benefício em se erradicar a infecção em pacientes com DRGE. Este estudo apoia a hipótese de que a erradicação do H. pylori não influencia a DRGE.

A Ten-year Follow-up of a Case with Gastric Adenoma Accompanied with Gastritis Cystica Profunda Treated by Endoscopic Submucosal Dissection / 대한소화기학회지

Gastritis cystica profunda (GCP) is an uncommon hyperplastic benign lesion, and histologically characterized by hyperplasia and cystic dilatation of the gastric glands extending into the submucosal layer. GCP usually occurs at a gastroenterostomy site, although it can occasionally be found in an unoperated stomach. GCP is thought to be a possible precancerous lesion, since a few early gastric cancers associated with it were reported. Herein, we report a case of gastric adenoma associated with GCP in an unoperated patient. The sizes of both the GCP and adenoma overlying it have increased during a 10 year follow-up period. Adenoma on the latest biopsy showed low grade dysplasia, and it was successfully treated by endoscopic submucosal dissection.

Absceso gástrico secundario a gastritis eosinofílica: reporte de un caso pediátrico / Gastric abscess secondary to eosinophilic gastritis: report of a pediatric case

Introducción: El absceso de pared gástrica es una enfermedad poco común, a menudo de evolución fatal, caracterizada por infección bacteriana de la pared gástrica. El diagnóstico es tardío en la mayoría de los casos. Se asocia frecuentemente con algún tipo de inmunocompromiso. No encontramos reportes de casos secundarios a gastritis eosinofílica. El tratamiento debe ser médico y quirúrgico. El tratamiento médico solo, puede ser exitoso. Presentación de caso: Adolescente de 11 años de edad, masculino, con historia de 15 días de evolución de caída desde 2 metros, sobre región abdominal, posteriormente presentó dolor, fiebre, náuseas y vómitos. Pérdida de peso importante desde el inicio del cuadro y tumoración en epigastrio de crecimiento progresivo, FR: 24 x´ FC: 120 x´ T: 37,5ºC TA 120/80 mm Hg GB: 19.900 N: 84% E: 7% L: 9% Hb: 13,6 gr/dl Hto: 40% plaquetas: 565.000 PCR: positiva Urea 26 mg/dl, creatinina 0,7 mg/dl, bilirrubina 0,13 mg/dl, FA: 485 UI/L GOT 23 UI/L GPT 22UI/L TAC de abdomen engrosamiento parietal circunferencial de toda la cavidad gástrica. Recibió cefazolina más amikacina. Por desmejoría del cuadro se amplió a piperacilina - tazobactam + vancomicina mejorando parcialmente. Se realizó endoscopia digestiva y se realizó el diagnóstico de gastritis eosinofílica. Luego del agregado de corticoides la mejoría se aceleró. Discusión: Los abscesos de pared gástrica son una patología rara en la infancia y obliga a descartar cuadro subyacente.

GIST Yeyunal con Sangrado Digestivo de Origen Oscuro / Jejunal GIST with obscure gastrointestinal bleeding

Reportamos el caso de una mujer de 84 años con antecedentes de arritmia cardiaca y hemorroides. Tenía múltiples hospitalizaciones y transfusiones por anemia ferropénica sintomática; los estudios endoscópicos solo demostraron divertículos y pequeños pòlipos de colon. Posteriormente fue hospitalizada por presentar heces sanguinolentas de color rojo vinoso; la endoscopia alta indicó gastritis y la colonoscopia mostró pequeñas úlceras colónicas, un pólipo colónico y múltiples divertículos. Meses después, reingresó con hemorragia de origen oscuro; en esa ocasión se demostraron: gastritis, erosiones antrales, pequeños pólipos colónicos y úlceras colónicas en vías de cicatrización; la cápsula endoscópica mostró probable angiodisplasia en yeyuno medio, la enteroscopia anterógrada detectó en yeyuno proximal algunas lesiones eritematosas sin evidencia de sangrado activo. Volvió a ser hospitalizada por melena y dolor abdominal, la endoscopia alta mostró angiodisplasias gástricas y duodenales que fueron tratadas. El último ingreso indicó un tiempo de enfermedad de dos años, el episodio se caracterizó por presentar deposiciones rojo vinosas y anemia. La endoscopia mostró angiodisplasia gástrica, que fue tratada con termocoagulación con argón plasma. En el examen no presentó signos de descompensación hipovolémica. Enfocado como un problema de hemorragia digestiva de origen oscuro se repitieron varios exámenes endoscópicos sin resultados. Resangró estando hospitalizada, se realizó cápsula endoscópica que demostró sangrado agudo en yeyuno, se complementó con nueva enteroscopia anterógrada que mostró lesiones ulceradas de yeyuno, se marcó el área con tinta china y se indicó laparotomía exploratoria. En la intervención quirúrgica se encontró en borde antimesentérico de yeyuno, una tumoración redondeada (6x6x4.5 cm) de crecimiento extraluminal, que comprometía la pared sin adherirse a otras estructuras; se realizó resección del tumor y anastomosis yeyuno-yeyunal. El estudio histológico -con inmunohistoquímica- del espécimen mostró que se trataba de un Tumor Estromal Intestinal (GIST), de riesgo intermedio, patrón histológico fusiforme, con escasas mitosis, dependiente de la capa muscular propia del intestino delgado. En conclusión el presente caso se trata de una mujer con un GIST yeyunal cuya presentación clínica fue una hemorragia de origen oscuro que constituyó un problema diagnóstico y que gracias al advenimiento de los nuevos procedimientos endoscópicos (enteroscopia y cápsula endoscópica) fue localizada y posteriormente extirpada quirúrgicamente.

We report the case of a woman of 84 years with a history of cardiac arrhythmia and hemorrhoids. She had multiple hospitalizations and transfusions for symptomatic iron deficiency anemia, endoscopic studies showed only small diverticula and colon polyps. He was later hospitalized with bloody stools red wines, upper endoscopy and colonoscopy showed gastritis, small colonic ulcers, colonic polyp and multiple diverticula. Readmitted with bleeding of obscure origin, on that occasion showed gastritis, antral erosions, small ulcers, colon polyps and colon ulcers in the process of healing, capsule endoscopy showed angiodysplasia in jejunum, anterograde enteroscopy detected some erythematous lesions in proximal jejunum without evidence of bleeding. Again hospitalized for melena and abdominal pain, upper endoscopy revealed gastric and duodenal angiodysplasia were treated. The last entry indicated a time of two years disease, the current episode with wine-red colored stools, Hb: 8.4 g, for which he received two units of PG. Endoscopy showed gastric angiodysplasia, which was treated with thermocoagulation (argon plasma). In the entrance examination showed no signs of hypovolaemic decompensation. Approached as a problem of obscure gastrointestinal bleeding were repeated several endoscopic examinations without results. She re-bled being hospitalized, capsule endoscopy was performed showing acute bleeding in the jejunum, complemented by new anterograde enteroscopy that showed ulcerated lesions of the jejunum, the area was marked with indian ink. Exploratory laparotomy was indicated. In the surgical intervention it was in edge antimesentérico of yeyuno, a round tumor (6x6 cm) of extraluminal growth, which compromised the wall without sticking to other structure, Resection of the tumor and jejuno-jejunal anastomosis was realized. The histological study with immunohistochemistry showed an Intestinal Stromal Tumor (GIST), intermediate risk, histological pattern fusiform, with scarce mitosis; the lesion was dependent on the muscularis propria of the small intestine. In conclusion, this case involves a woman with a jejunal GIST whose clinical presentation was hemorrhage of unknown origin which was a diagnostic problem and thanks to the advent of new endoscopic procedures (enteroscopy and capsule endoscopy) could locate the place of injury and subsequent surgery.

Linfoma MALT gástrico, gastritis linfocitaria y enfermedad celíaca: caso clínico con seguimiento a largo plazo, post erradicación de Helicobacter pylori y regresión del MALT. Correlación Clínico-Endoscópica-Patológica / Gastric MALT lymphoma, lymphocytic gastritis and celiac disease: case report with long-term follow-up post helicobacter pylori eradication and regression of MALT: clinical-pathological and endoscopic correlation

A case report of 61 year old female patient with diarrhea syndrome, whose study showed the presence of low-grade MALT gastric lymphoma associated with lymphocytic gastritis and celiac disease. During a six-year period of follow-up, the eradication of Helicobacter pylori determined the remission of the gastric lymphoma and lymphocytic gastritis; celiac disease showed variable activity according to their adherence to dietary treatment. We discuss possible associations and etiology of MALT lymphoma and lymphocytic gastritis, and of the latter with celiac disease.

Se presenta caso de paciente mujer de 61 años con cuadro de síndrome diarreico, cuyo estudio demuestra la presencia de linfoma MALT de bajo grado asociado a gastritis linfocitaria y enfermedad celíaca. Durante su seguimiento de 6 años, la erradicación de Helicobacter pylori, determinó la remisión del linfoma y gastritis linfocitaria, mientras la enfermedad celíaca mostró actividad variable de acuerdo con su adherencia al tratamiento dietético. Se discuten las posibles asociaciones y etiología de linfoma MALT y gastritis linfocitaria, y de esta última con enfermedad celíaca.

Primary Antibiotic Resistance of Helicobacter pylori Strains and Eradication Rate according to Gastroduodenal Disease in Korea / 대한소화기학회지

BACKGROUND/AIMS: This study was performed to evaluate whether the prevalence rates of primary antibiotic resistance in Helicobacter pylori (H. pylori) isolates and the eradication rate of H. pylori could be different between cancer and non-cancer patients. METHODS: H. pylori were isolated from gastric mucosal biopsy specimens obtained from 269 Koreans, who did not have any eradication therapy history and were diagnosed as one of the following diseases; chronic gastritis, benign gastric ulcer, duodenal ulcer or gastric cancer. The susceptibilities of the H. pylori isolates to amoxicillin, clarithromycin, metronidazole, tetracycline, azithromycin, ciprofloxacin, levofloxacin and moxifloxacin were examined with the agar dilution method. In addition, eradication rate of H. pylori was evaluated. RESULTS: There was no significant difference in the primary antibiotic resistance to above eight antibiotics among chronic gastritis, peptic ulcer disease and gastric cancer. Furthermore there was no difference of antibiotic resistance between cancer and non-cancer patients, and there was no difference of eradication rate of H. pylori according to disease. CONCLUSIONS: Primary antibiotic resistance and H. pylori eradication rate were not different between cancer and non-cancer patients.

A Case of Emphysematous Gastritis in a Patient with End-stage Renal Disease / 대한소화기학회지

Emphysematous gastritis is a rare infection of the stomach wall with high mortality rate. It is caused by gas forming organisms and may arise by local spread through the mucosa or hematogenous dissemination from distant focus. Clinical manifestation includes acute abdomen with systemic toxicity, and diagnosis is based on radiologic demonstration of gas within the gastric wall. Treatment should be aimed to cover gram-negative organisms and anaerobes using wide-spectrum intravenous antibiotics, and sometimes surgical management may be needed in order to enhance survival. Herein, we report a case of emphysematous gastritis in a patient with end stage renal disease on hemodialysis.

Gastritis Cystica Profunda Accompanied by Multiple Early Gastric Cancers / 대한소화기학회지

Gastritis cystica profunda (GCP) is a rare disease which shows multiple cystic gastric glands within the submucosa of the stomach. GCP lesions mainly develop at the site of gastroenterostomy and exhibit benign behavior. However, there have been a number of debates over its malignant potential. Several reports have documented GCP accompanied by gastric carcinomas, but the relationship between the two conditions remains uncertain. Here we report two cases of GCP with dysplasia accompanied by synchronous multiple early gastric cancers without previous gastric surgery.
