La gastroparesia es un trastorno crónico de la motilidad gástrica que genera un deterioro marcado de la calidad de vida y costos significativos en los sistemas de salud. Las terapias médicas son limitadas para su manejo, por lo cual ha surgido un entusiasmo creciente en las terapias dirigidas al píloro. La sonda de imagen luminal funcional (FLIP) ha demostrado ser una herramienta diagnóstica útil para evaluar las características del píloro, especialmente en casos refractarios, en los que podría guiar hacia una mejor estrategia de manejo y, en muchos casos, predecir la respuesta clínica.

Introducción: la obstrucción al tracto de salida gástrico o síndrome pilórico puede presentarse de manera secundaria a compromiso neoplásico, y es inusual el compromiso metastásico como etiología. Las neoplasias de la mama generalmente originan metástasis óseas, hepáticas y pulmonares, y es infrecuente el compromiso del tracto digestivo. Presentación del caso: se trata de una paciente de 69 años con carcinoma lobulillar infiltrante de mama derecha que consultó por dolor abdominal y episodios eméticos posprandiales con intolerancia a la vía oral y disnea. Se registró compromiso neoplásico mamario bilateral y dilatación de la cámara gástrica con engrosamiento del píloro. Se dio manejo antiemético y colocación de sonda nasogástrica. Fue llevada a endoscopia de vías digestivas altas en la que se encontró lesión ulcerada de aspecto infiltrativo a nivel pospilórico que comprometía de forma circunferencial la luz duodenal. Se tomó biopsia a este nivel que fue compatible con un carcinoma mamario de tipo lobulillar. Esta entidad, denominada síndrome pilórico por neoplasias, puede manejarse con gastroyeyunostomía o con prótesis enteral que mejore la calidad de vida en pacientes con pronóstico ominoso a corto plazo. La paciente de nuestro caso manifestó voluntades anticipadas para no recibir procedimientos invasivos, por lo cual se ofreció la colocación de una prótesis metálica descubierta y se logró el restablecimiento de la vía de alimentación y resolución de la disnea. Conclusiones: el compromiso metastásico de neoplasias de la mama al tracto digestivo es poco frecuente; sin embargo, debe sospecharse en pacientes de edad avanzada y con neoplasias previamente documentadas.

- Abstract
Introduction: Gastric outlet obstruction or pyloric syndrome can occur secondary to neoplastic involvement, and metastasis as an etiology is unusual. Breast neoplasms generally cause bone, liver, and lung metastases, rarely involving the gastrointestinal tract. Case presentation: A 69-year-old female patient with infiltrating lobular carcinoma of the right breast consulted for abdominal pain and postprandial emetic episodes with oral intolerance and dyspnea. Bilateral neoplastic breast involvement and dilation of the gastric chamber with thickening of the pylorus were recorded. She required antiemetic management and placement of a nasogastric tube. She was taken to an upper digestive tract endoscopy, which found an ulcerated lesion with an infiltrative appearance at the postpyloric level that circumferentially compromised the duodenal lumen. Then, a biopsy was taken, which was compatible with a breast carcinoma of a lobular type. This entity, called pyloric syndrome due to neoplasia, can be managed with gastrojejunostomy or an enteral prosthesis that improves the quality of life of patients with an ominous short-term prognosis. The patient in our case expressed advance directives not to receive invasive procedures, for which an uncovered metal prosthesis was placed for palliative purposes, achieving the re-establishment of the feeding route and resolution of dyspnea due to restriction. Conclusions: The metastatic involvement of neoplasms of the breast to the gastrointestinal tract is rare; however, it should be suspected in elderly patients with previously documented neoplasms.

La pancreatectomía total por trauma tiene una muy alta incidencia de complicaciones y una elevada tasa de mortalidad; y el manejo posterior de un paciente pancreatectomizado constituye un reto clínico y terapéutico. En el presente caso no había alternativa quirúrgica, dada la magnitud del trauma. El éxito del tratamiento se debió a la buena técnica quirúrgica, al refinado cuidado del estado crítico postoperatorio y al manejo metabólico moderno acorde con el buen entendimiento de los procesos metabólicos como respuesta al trauma. Se presentan pautas de manejo que pueden servir de guía para el cuidado de pacientes con estrés por trauma, y por cirugía de similar magnitud.

- Abstract
Hypertrophic pyloric stenosis it’s a frequent pathology present in newborns between 2 to 8 weeks of age, it’s more prevalent in male and first-born children, and it has an incidence of 1,5-5 cases in every 1000 newborns. It’s defined as a stenosis of the pyloric canal produced because of muscular hypertrophy of the pyloric wall. It’s the most common quirurgic cause of nonbilious vomiting in children. The etiology is unknown; however, a multifactorial origin is suggested, with genetic and environmental factors being involved. Generally, the clinical manifestations include postprandial vomiting, the finding of an olive shaped abdominal mass in the physical exam, and an hypochloremic metabolic alkalosis, produced by the loss of chlorohydric acid through vomiting. The diagnosis is mainly clinical, however there are methods such as the abdominal ultrasound and the upper gastrointestinal series that are useful in the confirmation of the diagnosis. The treatment of this pathology continues to be through surgery, by the realization of an extramucosa pyloromyotomy, this method has very few complications and it has a good overall outcome., La estenosis hipertrófica de píloro es una patología frecuente en neonatos entre 2 a 8 semanas de edad, se presenta más en niños varones y en primogénitos, tiene una incidencia de 1,5-5 casos por cada 1000 recién nacidos vivos. Se caracteriza por ser un estrechamiento del canal pilórico, generada como resultado de una hipertrofia de los músculos que forman el píloro y representa la causa quirúrgica más frecuente asociada a vómitos no biliosos en la infancia. Su etiología es desconocida, sin embargo, se sugiere un origen multifactorial, donde influyen tanto factores genéticos como ambientales. Generalmente las manifestaciones clínicas incluyen vómitos postprandiales, la presentación de una masa en forma de oliva a la exploración de abdomen, y una alcalosis metabólica hipoclorémica debido a la pérdida de grandes cantidades de ácido clorhídrico. El diagnóstico de la patología es clínico, sin embargo, métodos como el ultrasonido y la serie gastroduodenal con bario son útiles para la confirmación del diagnóstico. El tratamiento de la patología continúa siendo quirúrgico, mediante piloromiotomía extramucosa, la cual presenta un bajo índice de complicaciones y tiene un buen pronóstico general.

Objective: To determine clinical and epidemiological characteristics of hypertrophic pyloric stenosis in a hospital in Lima, Peru. Materials and Methods: A descriptive and retrospective study encompassing years 2013 to 2019 was performed in the Pediatric Surgery Service of San Bartolome Teaching Mother and Child Hospital. Data from clinical records of patients diagnosed with hypertrophic pyloric stenosis was collected. Results: Records from fifty-nine patients were obtained, 79% were male, 68.4% were first born, and their mean age was 31.3 ± 13.6 days. All patients (100 %) had vomit, 44.1% had abnormal abdominal movement, and only 35.6% had palpable pyloric olive. The average surgical correction time was 51.39 minutes, and the average hospital stay was 6.35 days, major complications occurred in 13.6% of all children, and the mortality rate was 3.4%. Conclusions: Early initiation of oral intake is important, as well as post-surgical management in these patients, in order to reduce their in-hospital stay and the development of post-surgical ventilatory complications., Objetivo: Determinar las características clínicas y epidemiológicas de la estenosis hipertrófica de píloro en un hospital de Lima,Perú.

Solitary gastric plexiform neurofibroma (PN) is a very rare tumor that originates from the peripheral nerves. PN is a rare cause of pyloric obstruction. A 58 year-old man, reported epigastric discomfort, nausea, and vomiting for two months. Upper digestive endoscopy showed a moderate/accentuated pyloric stenosis. Computed tomography (CT) and echoendoscopy revealed a pyloric nodule. The patient underwent to distal gastrectomy. Macroscopically, a gray nodule measuring 1.1 × 1.0 × 1.0 cm was identified. Using microscopy, a benign tumor composed of enlarged tortuous nerve fascicles showing a neurofibromatous proliferation with mild atypia and myxoid matrix was found. The lesion showed positive immunoexpression for S100, Leu7, and epithelial membrane antigen (EMA), and was negative for CD117, DOG-1, desmin, and smooth muscle actin. The diagnosis of PN was then determined.

Neste trabalho, é descrito um caso de estenose hipertrófica de piloro diagnosticado por gastroscopia em um eqüino Quarto de Milha, de quatro anos de idade, que apresentava inapetência, emagrecimento progressivo, cólica, bruxismo e sialorréia. A gastroduodenite ulcerativa crônica e os espasmos prolongados foram as supostas causas da hipertrofia da musculatura circular do piloro, causando a estenose. O tratamento com substâncias antiulcerativas é paliativo e o acesso cirúrgico ao piloro no animal adulto é complexo, sendo o prognóstico duvidoso.A case of hypertrophic pyloric stenosis diagnosed by gastroscopy was reported in a 4-years-old Quarter Horse gelding, with signs of inappetence, chronic weight loss, colic, bruxism and sialorrhea. Gastroduodenal ulceration and spasms were supposed as causes of pyloric muscular hypertrophy and stenosis. Antiulcerative medications are merely palliative and the complex surgical approach to the site of stenosis makes the prognostic to be doubtful.

La pancreatoduodenectomía fue introducida por Kaush en 1912 y popularizada por Whipple en 1935. Su uso se ha incrementado en los últimos años y ha probado ser una opción en algunos pacientes bien seleccionados con cáncer periampular y de la cabeza del páncreas. La preservación del antro y del píloro es el resultado del esfuerzo para reducir las complicaciones asociadas con el procedimiento tradicional, reconstruyendo el tracto gastrointestinal en una forma más fisiológica. Su uso en pacientes con cáncer de la cabeza del páncreas es controversial. El propósito de este estudio es revisar en forma retrospectiva la evolución de 5 pacientes con cáncer de páncreas y periampular, a los que se les hizo una pancreatoduodenectomía con preservación de píloro en nuestro servicio en el primer cuatrimestre de 2003.

Background: The delay in gastric emptying is the second most frequent complication after duodenopancreatectomy with pyloric preservation, that increases hospitalization time and hospital costs. Aim: To identify factors that contribute to the appearance the delay in this surgical procedure. Method: Ninety-five patients were submitted to duodenopancreatectomy with pyloric preservation. After retrospective analysis of the medical records, it was observed that 60 had prolonged hospitalization due to complications. Thus, univariate and multivariate logistic regression were used to analyze predictors of delayed gastric emptying. Results: Delay was present in 65% (n=39) and pancreatic fistula in 38.3% (n=23). Univariate analysis revealed that the presence of pancreatic complications (pancreatic fistula, p=0.01), other intracavitary complications with the appearance of abdominal collections (p=0.03) and hypoalbuminemia (p=0.06) were responsible, also confirmed by the multivariate analysis. In those who presented delay without a determined cause, it was observed that high levels of total bilirubin (p=0.01) and direct bilirubin (p=0.01) could be related to it. Conclusion: The delay in gastric emptying in patients undergoing duodenopancreatectomy with pyloric preservation is due to intracavitary complications. RESUMO Racional: O retardo do esvaziamento gástrico é a segunda complicação mais frequente após a realização da duodenopancreatectomia com preservação pilórica, aumentando o tempo de internação e custos hospitalares. Objetivo: Identificar fatores que contribuem para o aparecimento desse retardo nesse procedimento cirúrgico. Método: Noventa e cinco doentes foram submetidos à duodenopancreatectomia com preservação pilórica. Após análise retrospectiva dos prontuários observou-se que 60 apresentaram internação prolongada por complicações. Assim, utilizou-se a regressão logística uni e multivariada para análise de fatores preditores do retardo. Resultados: O retardo esteve presente em 65% (n=39) e a fístula pancreática em 38,3% (n=23). A análise univariada revelou que a presença de complicações pancreáticas (fístula pancreática, p=0,01), outras complicações intracavitárias com aparecimento de coleções abdominais (p=0,03) e hipoalbuminemia (p=0,06) foram os responsáveis, resultados estes também confirmados pela análise mutilvariada. Naqueles que apresentaram retardo sem causa determinada, observou-se que níveis elevados de bilirrubina total (p=0,01) e bilirrubina direta (p=0,01) poderiam estar relacionados a ele. Conclusão: O retardo do esvaziamento gástrico nos pacientes submetidos à duodenopancreatectomia com preservação pilórica é decorrente de complicações intracavitárias.

Resumen La hernia diafragmática traumática es una entidad inusual en los adultos que suele ser diagnosticada tardíamente, y se acompaña de una alta mortalidad cuando ya existe compromiso vascular. El abordaje abdominal es utilizado con más frecuencia en la hernia diafragmática traumática aguda y el abordaje torácico en la hernia diafragmática traumática crónica. Presentamos el caso clínico de una paciente femenina que sufrió caída de altura, ocasionándole una hernia diafragmática traumática con sección subtotal del píloro, dejando prácticamente separados estómago y duodeno, con diagnóstico tardío. Cuando la hernia diafragmática traumática causa una oclusión intestinal y existe además compromiso vascular con perforación o sepsis, la mortalidad es del 50 al 80 %. Ante un trauma que pueda ocasionar alteraciones en las cavidades torácicas y abdominales, se debe pensar en la hernia diafragmática traumática como un diagnóstico posible, para prevenir las complicaciones como consecuencia de un diagnóstico tardío.

Scientific literature, although limited in this area, supports the hypothesis that asthma, by means of selective leukocyte trafficking between the various mucosal and glandular sites of the body. can have the same pathophysiological effects on the stomach as the airways. This study aimed to determine if asthma, in the absence and presence of various asthma therapies (Hydrocortisone and ModuI8TM), imparted any morphological alteration on the stomach parietal and chief cells. The BALB/c murine asthmatic mouse model was the model of choice in this study. The asthma induction protocol as well as the asthma therapies were proved to be effective with the aid of bronchial lavage fluid leukocyte quantification. Fundic and pyloric biopsies were extracted at termination and assessed by means of transmission electron, scanning electron and light microscopy. The extracted fundic and pyloric biopsies revealed asthma alone induced parietal cell hypertrophy (increase in parietal cell size P<0.000100 in both stomach regions) and chief cell hyper functioning. The use of Hydrocortisone and Modul8TM, as a therapy to correct the perceived gastric alterations were dismal; only in the case of fundic parietal cells were both treatments able to compensate for the hypertrophic effect caused by asthma, while in the pylorus parietal cell asthma- induced hypertrophy was only compensated for by Modul8TM.

A case of hypertrophic pyloric stenosis diagnosed by gastroscopy was reported in a 4-years-old Quarter Horse gelding, with signs of inappetence, chronic weight loss, colic, bruxism and sialorrhea. Gastroduodenal ulceration and spasms were supposed as causes of pyloric muscular hypertrophy and stenosis. Antiulcerative medications are merely palliative and the complex surgical approach to the site of stenosis makes the prognostic to be doubtful. [ABSTRACT FROM AUTHOR]

Background During the Spanish colonisation of South America, African slaves and Europeans arrived in the continent with their corresponding load of pathogens, including Helicobacter pylori. Colombian strains have been clustered with the hpEurope population and with the hspWestAfrica subpopulation in multilocus sequence typing (MLST) studies. However, ancestry studies have revealed the presence of population components specific to H. pylori in Colombia. The aim of this study was to perform a thorough phylogenomic analysis to describe the evolution of the Colombian urban H. pylori isolates. Results A total of 115 genomes of H. pylori were sequenced with Illumina technology from H. pylori isolates obtained in Colombia in a region of high risk for gastric cancer. The genomes were assembled, annotated and underwent phylogenomic analysis with 36 reference strains. Additionally, population differentiation analyses were performed for two bacterial genes. The phylogenetic tree revealed clustering of the Colombian strains with hspWestAfrica and hpEurope, along with three clades formed exclusively by Colombian strains, suggesting the presence of independent evolutionary lines for Colombia. Additionally, the nucleotide diversity of horB and vacA genes from Colombian isolates was lower than in the reference strains and showed a significant genetic differentiation supporting the hypothesis of independent clades with recent evolution. Conclusions The presence of specific lineages suggest the existence of an hspColombia subtype that emerged from a small and relatively isolated ancestral population that accompanied crossbreeding of human population in Colombia.

- Abstract
A disorder produced by hypertrophy of pyloric muscle, which generates progressive blockage of gastric emptying. The specific etiology is currently unknown, although there are hypotheses that seek to explain its origin. Most of the cases are presented around 4 weeks of life, affecting mainly males, white, first-born, rural population and bottle-fed, and there is a clear family predisposition. Vomiting is a constant symptom and characteristically is inmediately postprandial, often in projectile and not bilious, which could trigger dehydration, malnutrition, metabolic and hydroelectrolyte alterations. In a patient whom presents this clinic, finding distension, peristaltic gastric waves and palpation of pyloric olive mass, can be diagnosed in most of the patients. In case of doubt, ultrasound can be use, that currently is the Gold Standart. The initial management should be the metabolic and hydroelectrolytic correction and subsequently the definitive surgical treatment; Ramstedt pyloromyotomy, after decades, continuous as the procedure o choice, althought new studies shown promising results with other surgical thechniques., Trastorno producido por hipertrofia del músculo pilórico, que genera obstrucción progresiva del vaciamiento gástrico. Actualmente se desconoce la etiología específica, aunque existen hipótesis que buscan explicar su origen. La mayoría de los casos se presenta alrededor de las 4 semanas de vida, afectando principalmente a varones, de raza blanca, primogénitos, de población rural y alimentados con biberón, existiendo una clara predisposición familiar. El vómito es el síntoma constante y característicamente es postprandial inmediato, con frecuencia en proyectil y no bilioso, que pude desencadenar deshidratación, desnutrición, y alteraciones metabólicas e hidroelectrolíticas. En un paciente con dicha clínica, al encontrar distención y ondas peristálticas gástricas y palpación de masa olivar pilórica puede hacerse el diagnostico en la mayoría de los pacientes. En caso de duda, se recurre al ultrasonido que actualmente es el Gold Standard. El manejo inicial debe ser la corrección metabólica e hidroelectrolítica y posteriormente el tratamiento quirúrgico definitivo; la pilorotomía de Ramstedt, después de décadas, continúa siendo el procedimiento de elección, aunque nuevos estudios presentan prometedores resultados con otras técnicas quirúrgicas.

Trabajo de fin de grado. Grado en Medicina. Curso académico 2016-2017, [ES] Introducción: la estenosis hipertrófica de píloro (EHP) es una patología que requiere una intervención precoz por las importantes alteraciones hidroelectrolíticas que causa en niños de pocas semanas de vida. Generalmente, la anestesia general (AG) es la opción predominante para poder operar a estos niños, aunque desde hace unos años se observa un aumento del uso de la anestesia espinal (AE). Objetivos: el propósito de este trabajo es evaluar si la AE tiene menores tasas de morbimortalidad que la AG en una cohorte de niños sanos. Métodos: se analizaron 33 ítems de las historias clínicas de niños intervenidos de EHP en el Hospital Universitario de Salamanca y se evaluaron mediante estadística descriptiva y estadística inferencial ( test de la T de Student y Chi-cuadrado). En la AE, se sedó a la mayoría de los niños con midazolam y ketamina, tras lo cual se empleó bupivacaína para generar el bloqueo espinal. Resultados: el estudio incluyó a 68 pacientes, de los cuales 20 fueron sometidos a AE. La mayoría de ellos eran varones. Se produjeron 5 episodios de apnea en los pacientes sometidos a AG mientras que no hubo ningún episodio de apnea en la AE (P=0,00). El tiempo de inducción fue menor en AE que en AG (P=0,027), igual que el tiempo total en el quirófano (P=0,048). La presión arterial sistólica fue, en general, mayor en la AE que en la AG (P=0,022), y no se registraron presiones por debajo de 70 mmHg. El nivel en el que más punciones se registraron fue en el espacio intervertebral entre la cuarta y la quinta vértebra lumbar. Se registraron un 7% más de complicaciones técnicas en la AG que en la AE. La estancia en la unidad de cuidados intensivos pediátricos tras AG fue mayor que tras AE (P=0,044). Discusión: la aparición de eventos adversos como apnea o hipotensión, es menor en los pacientes bajo AE. Esto, unido al menor tiempo dentro del quirófano y estancias en la unidad de cuidados intensivos pediátricos de menor duración, apoyan los datos de otros estudios sobre la seguridad de la AE en EHP.

Helicobacter pylori is a Gram-negative microaerophilic bacterium. It has been estimated that it colonizes half of the human population (1, 2). The prevalence of the infection correlates with the socioeconomic status of the populations studied, more frequently affecting developing rather than developed countries (3). The infection is associated with the development of chronic gastritis, gastric ulcer, and stomach cancer (4), although in most cases the infection persistsin the gastric mucosa without affecting the individual’s health (5). In this communication, we present the genome sequence of the strain Col2025. This strain was isolated from a 36-year-old man diagnosed with diffuse antral gastritis from Tibaná, Boyacá, a region with high gastric cancer risk in Colombia (6). Interestingly, neither CagA phosphorylation nor interleukin 8 (IL-8) secretion was detected when the strain Col2025 was cultured with AGS cells. To obtain a genome sequence, 1 g of DNA was fragmented by Covaris, and the fragments were repaired by attaching an A to the 3= end. Illumina adaptors were ligated to the fragments and selected for sizes between 400 and 500 bp. The size-selected fragments were amplified by PCR and the final products validated in an Agilent Bioanalyzer. The short reads were assembled using SOAPdenovo (7). Finally, the sequences were annotated in GenBank using the NCBI Prokaryotic Genomes Automatic Annotation Pipeline (PGAAP) according to the submission guidelines (http://www.ncbi.nlm.nih.gov/genbank/genomesubmit.html). Overall, this whole-genome shotgun sequencing revealed the following data: scaffolds, 54; contigs, 73; N50, 60,455; L50, 9; genome size, 1.64; GC content, 38.9%; proteins, 1,451; rRNAs, 3; tRNAs, 36; genes, 1,543; pseudogenes, 52. This genome and others sequenced using strains isolated in Colombia (8, 9) will be the basis for evolutionary computational studies. Nucleotide sequence accession number. This whole-genome shotgun project has been deposited in DDBJ/ENA/GenBank under the accession no.

- Abstract
Pyloric stenosis, is one of the main causes of intestinal obstruction in infants. Its diagnosis is mainly clinical, radiological images are used in cases of diagnostic doubt or when the disease is in the initial stage, considering the first-line ultrasound because of its high sensitivity and specificity. Its etiology is unknown despite the fact that different theories have been described. A Pyloromyotomy is the treatment of choice which produces minimal complications and few residences., La estenosis pilórica, es una de las principales causas de obstrucción intestinal en lactantes. Su diagnóstico es principalmente clínico, se utiliza imágenes radiológicas en caso de duda diagnostica o cuando la enfermedad se encuentra en etapa inicial, considerándose el ultrasonido de primera líneas por su alta sensibilidad y especificidad. Se desconoce su etiología a pesar de que se han descrito distintas teorías. La piloromiotomia es su tratamiento de elección el cual produce mínimas complicaciones y pocas resididas.

Antecedentes: la obstrucción primaria y adquirida al vaciamiento gástrico fue descrita en 1997, cuando se dieron a conocer los primeros reportes; es una entidad infrecuente y poco conocida entre cirujanos pediátricos, por lo tanto, el objetivo de este trabajo es presentar un caso clínico y ofrecer una sucinta revisión de esta patología. Caso clínico: se presenta el caso de una niña de 3 años de edad, con cuadro de 3 meses de evolución de vómitos no biliosos posprandiales que fueron intensificándose, dolor abdominal y pérdida de peso. Se le realizó una serie esófago gastroduodenal, la cual mostró un estómago dilatado y un vaciamiento gástrico muy retardado, con medio de contraste hasta 72 horas después. Se complementó con una endoscopia digestiva alta, que mostraba un píloro estenótico con biopsia reportada sin malignidad, ni proceso inflamatorio específico. Sin respuesta al tratamiento médico. Se le realizó una laparoscopia diagnóstica, descartando alguna causa de compresión extrínseca y visualizando un píloro de apariencia normal, por lo que se decidió efectuar una antropiloroplastía tipo Heineke-Mikulicz laparoscópica, que descartó la presencia de una membrana, pero se encontró un anillo fibrótico pilórico que se resolvió con la cirugía. Evolución postoperatoria satisfactoria. Discusión: el caso de la niña se agrupa en la categoría de obstrucciones primarias y adquiridas al vaciamiento gástrico o enfermedad de Jodhpur, caracterizada por un cuadro clínico de vómitos no biliosos, peristalsis gástrica visible, pérdida de peso, todos los síntomas sin causa aparente (no membrana o diafragma), con estudio histológico que descarta otra enfermedad (no fibrosis, no inflamación específica, no malignidad), y se resuelve satisfactoriamente con una piloroplastía tipo Heineke-Mikulicz. El caso analizado muestra que aunque esta entidad es rara, se debe empezar a considerar tras descartar otras enfermedades más comunes, y que el abordaje laparoscópico de la antropiloroplastía es seguro y efectivo. Background: Primary and acquired gastric outlet obstruction was described in 1997 when the first reports were released. It is an unusualillness, widely unknown among pediatric surgeons; therefore the aim of this paper is to present a case and provide a brief analysis of the disease. Case report: We report the case of a three-year old girl, with a three-month history of worsening postprandial non-bilious vomiting, abdominal pain and weight loss. The upper gastrointestinal contrast study showed an enlarged stomach and delayed gastric emptying, with contrast up to 72 hours later. Endoscopy displayed a stenotic pylorus. The result of the histopathologic examination was normal. Nonetheless, she didn’t respond to medical treatment. A diagnostic laparoscopy wasperformed,butextrinsiccompressioncausesweredismissed and it showed a normal pylorus, so a laparoscopic Heineke-Mikulicz antropyloroplasty was performed. It dismissed the presence of a membrane but showed a fibrotic pyloric ring that was resected. She presented a satisfactory postoperative course. Discussion: This case is grouped in the category of primary and acquired obstructions to gastric emptying or Jodhpur’s Disease, which is characterized by clinical symptoms like non-bilious vomiting, visible gastric peristalsis and weight loss with no apparent cause (no membrane or diaphragm); a histopathological study that dismissed other pathologies (no fibrosis, no specific inflammation, no malignancy) and by the fact that it may be easily resolved using a Mikuliczpyloroplasty. This case shows that although this is a rare entity, it should be considered after ruling out other more common diseases. It is also possible to conclude that the laparoscopic approach for antropyloroplasty is safe and effective.

El Doble Píloro (DP) es un hallazgo endoscópico inusual en el que el antro gástrico se conecta al bulbo duodenal por dos orificios separados por un septo, tabique o puente. Su etiología puede ser congénita o adquirida siendo esta última la forma más común como complicación de una enfermedad ulcero péptica (EUP). La mayoría de las fistulas están localizadas en la curvatura menor de antro gástrico. En los casos de DP adquirido se han descrito tres teorías en cuanto a su formación. Puede presentarse con dolor en epigástrico, dispepsia o hemorragia digestiva aunque en ocasiones es un hallazgo casual endoscópico o radiológico. En este caso presentamos a un paciente quien acude con clínica de Hemorragia Digestiva Superior a quien se le realiza gastroscopia donde se evidencia este hallazgo poco usual el cual fue confirmado mediante estudio radiológico. En general el pronóstico es favorable. The Double Pylorus (DP) is an unusual finding in the gastroscopy where the gastric antrum and the duodenal bulb is connected to by two holes separated by a septum or bridge. Its etiology may be congenital or acquired the latter being the most common form as a complication of peptic ulcer disease (EUP). Most fistulas are located on the lesser curvature of the gastric antrum. There have been described three theories in the formation of acquired DP. It may present with epigastric pain, dyspepsia or gastrointestinal bleeding but sometimes it is an endoscopic or radiological incidental finding. We present a patient who presents with upper gastrointestinal bleedingsymptoms in whom a gastroscopy where performed with this unusual finding which was confirmed by radiological study. In general the prognosis is favorable.

Helicobacter pylori is the most common gastric bacteria of human beings. Animal-borne helicobacter have been associated with gastritis, ulceration, and gastric mucosa-associated lymphoid-tissue lymphoma in people. We attempted to identify the species of Helicobacter spp. that infect human beings in north Parana, Brazil. Samples of gastric mucosa from 38 dyspeptic patients were analyzed by optic microscopy on silver stained slides, polimerase chain reaction (PCR), and enzymatic cleavage. Genus and species-specific primers to H. pylori, H. heilmannii, H. felis, and consensual primers to H. bizzozeronii or H. salomonis were used. The PCR products were submitted to enzymatic cleavage by VspI (Helicobacter spp. product) and HinfI (species products) enzymes. Thirty-two out of 38 patients evaluated had 3.2 to 5 µm long bacteria that resembled H. pylori in Warthin-Starry stained slides and were positive to the genus Helicobacter by PCR. In 30 of these patients the bacteria were identified as H. pylori. Two samples positive by silver stain were negative to all species tested by PCR. None of the 38 samples was positive to animal-origin helicobacter species. These results show that PCR and enzymatic restriction are practical methods to identify the species of helicobacters present in gastric mucosa of human beings. People in north Parana appear to be infected mostly with H. pylori.

Solitary gastric plexiform neurofibroma (PN) is a very rare tumor that originates from the peripheral nerves. PN is a rare cause of pyloric obstruction. A 58 year-old man, reported epigastric discomfort, nausea, and vomiting for two months. Upper digestive endoscopy showed a moderate/accentuated pyloric stenosis. Computed tomography (CT) and echoendoscopy revealed a pyloric nodule. The patient underwent to distal gastrectomy. Macroscopically, a gray nodule measuring 1.1 × 1.0 × 1.0 cm was identified. Using microscopy, a benign tumor composed of enlarged tortuous nerve fascicles showing a neurofibromatous proliferation with mild atypia and myxoid matrix was found. The lesion showed positive immunoexpression for S100, Leu7, and epithelial membrane antigen (EMA), and was negative for CD117, DOG-1, desmin, and smooth muscle actin. The diagnosis of PN was then determined. Neurofibroma plexiforme (NP) gástrico solitário é um tumor muito raro originado a partir dos nervos periféricos. É uma causa rara de obstrução pilórica. Paciente masculino, 58 anos, relatava desconforto epigástrico, náuseas e vômitos durante dois meses. A endoscopia digestiva superior mostrou estenose moderada/acentuada do piloro. Tomografia computadorizada (TC)/ ecoendoscopia revelaram nódulo no piloro. O paciente foi submetido a gastrectomia distal. À macroscopia, identificou-se nódulo cinzento medindo 1.1 × 1 × 1 cm. À microscopia, encontrou-se tumor benigno composto por fascículos nervosos dilatados/ tortuosos, exibindo proliferação neurofibromatosa com atipias leves e matriz mixoide. A lesão exibiu imunoexpressão positiva para S100, Leu7 e antígeno da membrana epitelial (EMA), e negatividade para CD117, DOG-1, desmina e actina de músculo liso. O diagnóstico de PN foi, então, determinado.

The lesion showed positive immunoexpression for S100, Leu7, and epithelial membrane antigen (EMA), and was negative for CD117, DOG-1, desmin, and smooth muscle actin. The diagnosis of PN was then determined.

- Abstract
Introduction and Aims: Pyloric sphincter abnormalities may be detected in gastroparesis. Botulinum toxin A (BoNT/A) injection into the pylorus has been used to treat gastroparesis with varying results. The aim of the present article was to assess whether pyloric sphincter characteristics using the endoscopic functional lumen imaging probe (EndoFLIP
® ) with impedance planimetry in patients with gastroparesis correlated with symptoms, gastric emptying, and therapeutic response to pyloric sphincter BoNT/A injection., Methods: EndoFLIP® study was performed on patients undergoing gastroparesis treatment with BoNT/A. The gastroparesis cardinal symptom index (GCSI) was applied prior to treatment and at post-treatment weeks 2, 4, 8, and 12., Results: Forty-four patients were enrolled (30 with idiopathic gastroparesis, 14 with diabetic gastroparesis). Smaller pyloric diameter, cross-sectional area (CSA), and distensibility correlated with worse vomiting and retching severity at baseline. Greater gastric retention tended to correlate with decreased CSA and pyloric distensibility. BoNT/A treatment resulted in a significant decrease in the GCSI score at 2 and 4 weeks after treatment, but not at post-treatment weeks 8 or 12. Nausea, early satiety, postprandial fullness, and upper abdominal pain improved up to 12 weeks, whereas loss of appetite, stomach fullness, and stomach visibly larger improved only up to 4 weeks. Retching and vomiting failed to improve. Greater pyloric compliance at baseline correlated with greater improvement in early satiety and náusea at 8 weeks and greater pyloric distensibility correlated with improvement in upper abdominal pain., Conclusions: EndoFLIP® characteristics of the pylorus provided important pathophysiologic information in patients with gastroparesis, in relation to symptoms, gastric emptying, and predicting the response to treatment directed at the pylorus., (Copyright © 2018 Asociación Mexicana de Gastroenterología.

OBJETIVO: Estudar, experimentalmente, a diminuição do trânsito intestinal através de piloros artificiais no íleo terminal de ratos, sem secção da musculatura entérica. MÉTODO: O estudo foi realizado em 40 ratos distribuídos em dois grupos de 20 animais cada. Foram confeccionados quatro piloros no íleo terminal de cada animal, com pontos sero-musculares separados, distribuídos circunferencialmente na alça intestinal. O Grupo 1 foi morto com 15 dias e o Grupo 2, com 30 dias. Aferimos as medidas da circunferência do intestino no transoperatório e no momento da necrópsia. RESULTADOS: No Grupo 1 houve dilatação média de 3mm no nível do primeiro piloro e de 4,15mm no quarto piloro. No Grupo 2 a dilatação média foi de 7,50mm no primeiro piloro e de 5,75mm no quarto piloro. No estudo anátomo-patológico ficou evidente a formação bem definida dos piloros. CONCLUSÃO: Não é necessário remover ou seccionar a musculatura do intestino delgado, nem a secção do plexo nervoso próprio do intestino, para promover a dilatação intestinal com esse método e, como consequência, diminuir o trânsito intestinal. BACKGROUND: To study, experimentally, the reduction of intestinal transit through artificial pylorus in terminal ileum of rats, without sectioning the enteric muscles. METHODS: The study was carried out in two groups of 20 rats each. Four pylori were made in the terminal ileum of each animal with sero-muscular stitches circumferentially spread around the intestinal loop. Group 1 rats were killed after 15 days and those from group 2 after 30 days. The intestinal circumference was measured during surgery and post-mortem. RESULTS: Group 1 showed a mean 3mm dilatation in the first pylorum and 4.15mm in the fourth one. In group 2 the mean dilatation was 7.50 mm in the first pylorum and 5.75mm in the fourth one. The presence of the well defined formation of the pylori were evident from anatomical studies. CONCLUSION: It is thus not necessary to remove or section the small intestine muscles nor section the intestinal neural plexus to promote intestinal dilatation and reduce intestinal transit with this method.

OBJECTIVE: To establish the incidence of Infantile Hypertrophic Pyloric Stenosis (IHPS) at Hospital de Policia, its associated factors and propose a procedure guideline for IHPS. MATERIAL AND METHODS: Retrospective study of patients who underwent IHPS surgical repair in the Hospital de Policía Pediatric Surgery Department between January 1985 and December 1994. RESULTS: We found 44 cases (incidence 1,67 x 1 000 live-born children), 35 (79%) were male, and the average age of initiation was 3rd to 4th week of life (range: 16-67 days). Predominant symptom was vomiting (100%). All of them underwent pyloromiotomy (Fredet-Ramstedt’s technique). 45% of patients complains postoperative complications, and vomiting (27%) was the most frequent one. There was no mortality. CONCLUSION: Our clinical and epidemiological features for IHPS were similar to those observed in other studies. Mean age 3 to 5 weeks, male gender, first child, and breastfeeding were the most associated factors., Objetivo: Establecer la tasa de incidencia de Estenosis Hipertrófica Infantil Pilórica (EHIP) en el Hospital de Policía, los factores asociados a la misma y plantear un protocolo de manejo de EHIP. Materiales y Métodos: Estudio retrospectivo de revisión de casos de los pacientes operados por EHIP en el Servicio de Cirugía Pediátrica del Hospital Central de la Policía entre enero de 1985 y diciembre de 1994. Resultados: Se encontró 44 casos con una tasa de incidencia de 1,67 x 1000 nacidos vivos, principalmente varones (35 casos; 79%); la edad de presentación más frecuente fue entre la 3ra y 4ta semana de vida (rango: 16-67 días); el síntoma predominante fue el vómito posprandial (100%). A todos se les realizó piloromiotomía (técnica de Fredet-Ramstedt), presentando complicaciones posquirúrgicas el 45% de los pacientes, siendo la más frecuente el vómito (27%). La tasa de mortalidad fue cero. Conclusiones: Las características clínicas y epidemiológicas de la EHIP son similares a las presentadas en otros medios, los factores más asociados a esta entidad son: edad promedio entre 3 a 5 semanas, sexo masculino, ser primogénito y recibir lactancia materna.

Apresenta-se o caso clínico de uma mulher de 56 anos, raça branca, com úlcera duodenal e esofagite com 3 anos de evolução apesar de terapêutica mantida com bloqueadores dos receptores H2. O valor da gastrina sérica basal estava ligeiramenteacima dos limites superiores do normal. O teste de estimulação de secretina foi sugestivo de gastrinoma. Com tomografia axial computorizada e arteriografia selectiva não se localizou o tumor. Na laparotomia exploradora encontrou-se um nódulo pilórico que se demonstrou corresponder ao gastrinoma. Dezoito meses após a cirurgia a doente encontrou-se assintomática e os exames de controle são negativos.

- Abstract
Gastric adenomyomas are extremely uncommon benign tumors in children. On histologic examination, these tumors have an epithelial component similar to pancreatic ducts. We present a case of a pyloric adenomyoma that clinically simulated hypertrophic pyloric stenosis in a newborn girl. Imaging tests, fundamentally magnetic resonance imaging, were very important in the characterization and diagnosis of this entity., (Copyright © 2016 SERAM. Published by Elsevier España, S.L.U.

OBJETIVOS: A lesão duodenal é um evento pouco freqüente, que incide em 3% a 12% dos pacientes com trauma de abdome. A sutura dessa ferida e a drenagem adequada da região é o tratamento mais utilizado nas lesões menores. Entretanto, as feridas de maior dimensão continuam sendo um desafio para a escolha do melhor tratamento. O fechamento do piloro e o desvio do trânsito digestório por meio de anastomose gastrojejunal é a conduta mais freqüente nessas situações. Os objetivos deste estudo foram verificar se há diferença entre o tempo de reabertura pilórica após sua oclusão com diferentes fios e se a vagotomia influencia nas alterações tissulares locais. MÉTODO: Foram estudados 30 ratos, submetidos à cerclagem do piloro gastroduodenal e derivação gastrojejunal. Os animais foram divididos em três grupos (n = 10), de acordo com o tipo de fio utilizado no fechamento pilórico: categute simples, ácido poliglicólico e polipropileno. Metade dos animais de cada grupo (n = 5) foram também submetidos a vagotomia troncular. O estudo pós-operatório consistiu de radiografia abdominal após injeção intragástrica de contraste baritado, semanalmente até a constatação de trânsito gastroduodenal. Em seguida, as regiões pilórica e da anastomose gastrojejunal foram retiradas para análise histológica. A comparação entre os grupos foi feita pelo teste de Kaplan-Meier. RESULTADOS: O fio de polipropileno manteve o piloro fechado por mais tempo (36,3 ± 11,6 dias) em relação aos demais fios (p
