Frequency of functional esophageal disorders in patients with refractory reflux symptoms in Lima, Peru.

Gastroesophageal reflux disease (GERD) is a clinical condition in which gastric reflux causes symptoms or damage to the esophageal mucosa. It is managed with proton pump inhibitors, however, up to 45% of patients with suspected GERD are refractory to treatment. It is necessary to establish a true GERD diagnosis by means of a digestive endoscopy, which does not show lesions in approximately 70% of patients. In this scenario, it is necessary to perform an esophageal pH-impedance measurement, a procedure that allows to determine whether exposure to gastric acid is pathological. Of this group, patients with pathological acid exposure are diagnosed as true non-erosive reflux disease (NERD). If, in addition to not presenting esophageal lesions, they have a physiological exposure to gastric acid, they suffer from esophageal hypersensitivity or functional heartburn, which are functional disorders. These require a different approach from that of GERD or NERD, as the symptoms are not due to pathological exposure to gastric acid. The aim was to calculate the frequency of esophageal hypersensitivity and functional heartburn in patients with suspected NERD. This was a cross-sectional study. Data was collected by reviewing pH-impedance and manometry reports, 166 patients were selected. The frequency for functional disorders was 86.15%, being 46.9% for functional heartburn and 39.2% for esophageal hypersensitivity. The frequency of functional disorders was higher than that reported in previous studies. In conclusion, age, psychological conditions, dietary, cultural, ethnic or lifestyle factors inherent to our environment might play important roles in the development of functional disorders.

[Generation of a predictive test for the diagnosis of the etiology of variceal upper gastrointestinal bleeding]. / Generación de un test predictivo para el diagnóstico de la etiología de la hemorragia digestiva alta variceal.

Our objective was to develop a diagnostic test to predict the etiology of Variceal Upper Gastrointestinal Bleeding (VUGIB). We conducted a retrospective cohort study. Medical records of patients over 18 years of age with Upper Gastrointestinal Bleeding (UGIB) who attended the emergency service of Hospital Cayetano Heredia (HCH) in Lima-Peru between 2019 and 2022 were reviewed; demographic, laboratory and clinical data were collected. Subsequently, predictive variables of variceal upper gastrointestinal bleeding (VUGIB) were identified using multiple logistic regression. Each variable with predictive capacity was assigned a score with a cut-off point and served to build a predictive scale for VUGIB. 197 medical records of patients with UGIB were included, of which 127 (64%) had non-variceal bleeding, and 70 (36%), variceal. Four independent predictors were identified: hematemesis (red vomit) (OR: 4,192, 95% CI: 1.586-11.082), platelet count (OR: 3.786, 95% CI: 1.324-10.826), history of UGIB (OR: 2.634, 95% CI: 1.017-6.820), signs of chronic liver disease (OR: 11.244, 95% CI: 3.067-35.047), with which a predictive scale was constructed, with a cut-off point >7 and ≤7; which showed a sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative of 58.6%, 90.6%, 77.4%, 79.9%, 6.20, and 0.46 respectively. In conclusion, the predictive scale with a cut-off point >7 is useful for predicting the presence of VUGIB in patients who attend the emergency room for UGIB.

Generación de un test predictivo para el diagnóstico de laetiología de la hemorragia digestiva alta variceal

Nuestro objetivo fue desarrollar un test diagnóstico para predecir la etiología de la Hemorragia Digestiva Alta Variceal (HDAV). Realizamos un estudio de cohorte retrospectivo. Se revisaron historias clínicas de pacientes mayores de 18 años con Hemorragia Digestiva Alta (HDA) que acudieron al servicio de emergencia del Hospital Cayetano Heredia (HCH) de Lima-Perú entre el 2019 a 2022, se recolectaron datos demográficos, de laboratorio y clínicos; posteriormente, se identificaron variables predictivas de HDAV mediante una regresión logística múltiple. A cada variable con capacidad predictiva se les asignó un puntaje con un punto de corte y sirvió para construir una escala predictiva de HDAV. Se incluyeron 197 historias clínicas de pacientes con HDA, de los cuales 127 (64%) tuvieron sangrado de causa no variceal, y, 70 (36%), variceal. Se identificaron 4 factores predictivos independientes: hematemesis (vómito rojo) (OR: 4,192, IC 95%: 1,586-11,082), recuento de plaquetas (OR: 3,786, IC 95%: 1,324-10,826), antecedente de HDA (OR: 2,634, IC 95%: 1,017-6,820), signos de enfermedad hepática crónica (OR: 11,244, IC 95%: 3,067-35,047), con los que se construyó una escala predictiva, con un punto de corte >7 y ≤7; que mostró una sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo, cociente de probabilidad positivo, y, negativo de 58,6%, 90,6%, 77,4%, 79,9%, 6,20, y 0,46 respectivamente. En conclusión, la escala predictiva con un punto de corte >7 es útil para predecir la presencia de la HDAV en pacientes que acuden a la emergencia por HDA.

La enfermedad por reflujo gastroesofágico (ERGE) es una condición clínica en la que el reflujo gástrico provoca síntomas o daños en la mucosa esofágica. Se maneja con inhibidores de la bomba de protones; sin embargo, hasta el 45% de los pacientes con sospecha de ERGE son refractarios al tratamiento. Por lo cual, es necesario establecer un verdadero diagnóstico de ERGE mediante una endoscopia digestiva, que no muestra lesiones en aproximadamente el 70% de los pacientes. En este escenario, es necesario realizar una medición de pH-impedancia esofágica, procedimiento que permite determinar si la exposición al ácido gástrico es patológica. De este grupo, los pacientes con exposición patológica al ácido son diagnosticados como verdadera enfermedad por reflujo no erosiva (ERNE). Si además de no presentar lesiones esofágicas, tienen una exposición fisiológica al ácido gástrico, padecen hipersensibilidad esofágica o pirosis funcional, que son trastornos funcionales. Estos requieren un enfoque diferente al ERGE o ERNE, ya que los síntomas no se deben a una exposición patológica al ácido gástrico. El objetivo fue calcular la frecuencia de hipersensibilidad esofágica y pirosis funcional en pacientes con sospecha de ERNE. Este fue un estudio transversal. Los datos se recopilaron mediante la revisión de informes de pH-impedancia y manometría, se seleccionaron 166 pacientes. La frecuencia de trastornos funcionales fue de 86,15%, siendo 46,9% de pirosis funcional y 39,2% de hipersensibilidad esofágica. La frecuencia de trastornos funcionales fue superior a la reportada en estudios previos. En conclusión, la edad, las condiciones psicológicas, los factores dietéticos, culturales, étnicos o de estilo de vida inherentes a nuestro entorno podrían jugar un papel importante en el desarrollo de trastornos funcionales.

Resistencia antibiótica de Helicobacter pylori en la población peruana: una revisión sistemática y metaanálisis sobre su prevalencia en la población general

La infección por Helicobacter pylori es bastante común a nivel mundial, y tiene asociación con el adenocarcinoma gástrico. Las altas tasas de resistencia encontradas en países latinoamericanos justifican la investigación de tasas de resistencia local, lo que podría mejorar el enfoque terapéutico y las tasas de erradicación. El objetivo es evaluar la prevalencia de la resistencia de Helicobacter pylori a los antibióticos de uso común en Perú. Se incluyeron todos los estudios en población peruana que revelaron tasas de resistencia antibiótica de Helicobacter pylori. Se realizó una búsqueda sistemática de la literatura hasta enero del 2021, utilizando PubMed y otras bases de datos. Para el grupo de estudios de pacientes con punto de corte EUCAST, la resistencia fue la siguiente: Amoxicilina 14% (IC 95%: 6-25), Claritromicina 43% (IC 95%: 30-57), Metronidazol 58% (IC 95%: 22-90) y Quinolonas 51% (IC 95%: 38-64). Para el grupo de estudios de muestras con punto de corte EUCAST, los siguientes: Amoxicilina 57% (IC del 95%: 51-63), Claritromicina 35% (IC 95% 30-41), Metronidazol 67% (IC 95%: 62-72) y Tetraciclina 4% (IC 95%: 2-7). Se encontró una alta resistencia antibiótica de Helicobacter pylori en la mayoría de los grupos estudiados, aunque con heterogeneidad entre los estudios. La tasa de resistencia a tetraciclinas fue baja y los estudios mostraron ser homogéneos.

Helicobacter pylori infection is quite common worldwide and is associated with gastric adenocarcinoma. The high rates of resistance found in Latin American countries justify the investigation of local resistance rates, which could improve the therapeutic approach and eradication rates. The objective is to evaluate the prevalence of resistance in Peru of Helicobacter pylori to commonly used antibiotics. All studies in the Peruvian population that revealed rates of antibiotic resistance of Helicobacter pylori were included. A systematic literature search was conducted up to January 2021, using PubMed and other databases. For the group of patient studies with the EUCAST cut-off point, the resistance was as follows: Amoxicillin 14% (95% CI: 6-25), Clarithromycin 43% (95% CI: 30-57), Metronidazole 58% (95% CI: 22-90) and 51% Quinolones (95% CI: 38-64). For the EUCAST cut-off group of sample studies, the following: Amoxicillin 57% (95% CI: 51-63), Clarithromycin 35% (95% CI 30-41), Metronidazole 67% (95% CI: 62-72) and 4% Tetracycline (95% CI: 2-7). A high antibiotic resistance of Helicobacter pylori was found in most of the groups studied, although with heterogeneity between the studies. The rate of resistance to tetracyclines was low and the studies were shown to be homogeneous.

Endoscopic removal of a toothbrush in a young adult with psychiatric disorder / Extracción endoscópica de un cepillo de dientes en un adulto joven con trastorno psiquiátrico

ABSTRACT Ingestion of foreign bodies is a relative common situation in the emergency department; however, ingestion of toothbrush is rarely reported in the literature. We present the case of a 27-year-old man with a previous diagnosis of obsessive-compulsive disorder, who presented to the emergency department 17 hours after an ingestion of a toothbrush. We performed an endoscopic removal using a polypectomy snare in the Gastroenterology Department under moderate sedation. No complications were reported in the procedure and the patient was discharged few hours later. Ingestion of toothbrush is rare in the literature and some authors described techniques using overtube and retractable snares and forceps. Endoscopic removal of a toothbrush under moderate sedation can be a safe and successful procedure. However, if endoscopic removal fails, surgery should be performed.

RESUMEN La ingestión de cuerpos extraños es una situación relativamente común en el departamento de emergencias; sin embargo, la ingestión de cepillo de dientes rara vez se informa en la literatura. Presentamos el caso de un varón de 27 años con diagnóstico previo de trastorno obsesivo compulsivo, que acudió al servicio de urgencias 17 horas después de la ingestión de un cepillo de dientes. Realizamos una extirpación endoscópica usando un asa de polipectomía en el Servicio de Gastroenterología bajo sedación moderada. No se reportaron complicaciones en el procedimiento y el paciente fue dado de alta pocas horas después. La ingestión de cepillo de dientes es rara en la literatura y algunos autores describen técnicas que utilizan sobretubo y asas y fórceps retráctiles. La extracción endoscópica de un cepillo de dientes bajo sedación moderada puede ser un procedimiento seguro y exitoso. Sin embargo, si la extracción endoscópica falla, se debe realizar una cirugía.

Hepatitis A and hepatitis E virus co-infection with right pleural effusion, ascites and acute acalculous cholecystitis. A case report.

Hepatitis A and hepatitis E are the leading causes of acute viral hepatitis in developing countries due to our poor sanitary conditions, both spread by fecal-oral route or through contaminated water and food. Being both self-limiting diseases, they are usually benign but may present with atypical clinical findings. A 32 year-old female with right pleural effusion, ascites and acalculous cholecystitis during the course of HAV and HEV co-infection is reported. Clinical improvement was observed with conservative management. As far as we know, this is the first case described of a patient with these three complications in the background of a hepatitis A virus and hepatitis E virus co-infection.

[Independent risk factors for severity and mortality in lower gastrointestinal bleeding]. / Hemorragia digestiva baja, factores predictores de severidad y mortalidad en un hospital p úblico de Lima.

In lower gastrointestinal bleeding (LGIB), it is very important to stratify the risk of LGIB for a proper management. OBJECTIVE: Identity the independent risk factors to mortality and severity (require critical care, prolonged hospitalization, reebleding, re hospitalization, politrasfusion, surgery for bleeding control) in LGIB. MATERIALS AND METHODS: It is an analytic prospective cohort study, performed between June 2016 and April 2018 in a tertiary care hospital. Independent factors were determined using binomial logistic regression. RESULTS: A total of 98 patients were included, of which 13 patients (13,3%) died, and 56 (57,1%) met severity criteria. The independent risk factor for mortality was Glasgow scale under 15, and for severe bleeding were: Systolic blood pressure under 100 mm Hg, albumin lower than 2,8 g/dL. CONCLUSIONS: The frequency of mortality and severe LGIB is high in our population, the principal risk factors were systolic blood pressure under than 100 mm Hg, Glasgow score lower than 15, albumin lower than 2,8 g/dL. Identifying these associated factors would improve the management of LGB in the emergency room.

[Use of cyanoacrylate as a treatment of gastric varices in a public hospital in Lima - Peru]. / Uso de cianoacrilato como tratamiento de várices gástricas en un hospitalp úblico nivel III en Lima - Per ú.

OBJECTIVE: To evaluate the therapeutic success of endoscopic therapy with N-butyl-2-cyanoacrylate and to determine the re- bleeding and mortality rates. MATERIALS AND METHODS: Prospective analytical observational study of 47 cases of patients with gastric varices who were treated with N-butyl-2-cyanoacrylate, using a 1: 1 mixture with lipiodol between 2013 and 2017 in a level III public hospital in Lima - Peru. The therapeutic indication was active hemorrhage, primary or secondary prophylaxis. RESULTS: Of the 47 patients, 5 (10.6%) had active hemorrhage, control was obtained in all cases, 24 (51.1%) had stigmas of recent bleeding during endoscopy. Secondary prophylaxis was performed in 16 (34%) patients and primary prophylaxis in 2 (4.7%). 59.6% required a single session with a total volume of cyanoacrylate (ml / patient) of 1.28 ± 0.44. The endoscopic finding was GOV-2 in 78.7% of the cases, IGV-1 in 12.8% and GOV-1 in 8.5%. Seven patients (14.8%) presented late re- bleeding, with successful new therapy in 6 of them, one dying due to therapy failure. Of the six (12.76%) patients who died in total, 5 (83.3%) were due to other causes. No adverse events related to the therapy were reported. No adverse events were reported. Variceal obturation was observed in 28 (59.5%) patients. CONCLUSIONS: Endoscopic management of gastric varices with cyanoacrylate is a safe and effective treatment, with low recurrence and mortality rates.

[Colonic balantidiasis: report of a fatal case and review of the literature]. / Balantidiasis colónica: reporte de un caso fatal y revisión de la literatura.

Balantidiasis is a zoonosis produced by Balantidium coli, which inhabits the large intestine of the pig and man. Infection is uncommon in humans and mainly affects the colon. It occurs more frequently in developing countries, tropical and subtropical regions. Colonic balantidiasis can occur in most cases asymptomatically and reach in the most severe cases such as dysenteric diarrhea that can be complicated by low digestive bleeding and even perforation. We present the case of a 72-year-old man, from the Peruvian highlands, who was a farmer and breeder of swine and sheep, who came for 3 months of illness, initially characterized by liquid stools with bloodless mucus, abdominal pain, nausea, vomiting and in the last month of illness he presents dysenteric diarrhea. Colonoscopy was performed due to suspicion of infectious colitis, Balantidium coli trophozoites were found in the fresh sample and colonic tissue biopsy. Patient receives treatment with amebicide and antibacterial without clinical improvement, presenting as a complication multiple perforation in the sigmoid colon, treated with resection and terminal colostomy. Finally, the patient died despite receiving medical and surgical treatment.

Hemorragia digestiva baja, factores predictores de severidad y mortalidad en un hospital público de Lima

En hemorragia digestiva baja (HDB) es muy importante estratificar el riesgo de la misma para brindar un manejo adecuado. Objetivo: Identificar los factores predictores de mortalidad y severidad en pacientes con HDB (definida como: requerimiento de unidad de cuidados críticos, control de hemorragia en sala de operaciones, estancia prolongada mayor a 9 días, resangrado, reingreso, o politransfusión más de 5 paquetes globulares). Materiales y métodos: Es un estudio observacional analítico de cohorte prospectivo, realizado entre junio del 2016 y abril del 2018 en un hospital de nivel III. Se determinó los factores predictores de mortalidad y severidad. Se evalúo la sobrevida hasta los 30 días Resultados: Se incluyó un total de 98 pacientes de los cuales 13 pacientes (13,3%) fallecieron y 56 (57,1%) cumplen criterios de severidad. El factor predictor independiente de mortalidad fue escala de Glasgow menor a 15 y los factores independientes de severidad fueron un valor de albúmina menor a 2,8 g/dl y la presión arterial sistólica menor a 100 mmhg. Conclusiones: La frecuencia de mortalidad y HDB severa es alta en nuestro estudio. La presión arterial sistólica, la escala de Glasgow y la albúmina sérica son evaluaciones que pueden permitirnos predecir durante la primera evaluación en emergencia el riesgo de severidad y mortalidad de un paciente con HDB.

[Prevalence of histological types of gastric polyps in adult patients from a public hospital in Lima-Peru (2007 - 2016)]. / Prevalencia de tipos histológicos de pólipos gástricos en pacientes adultos de un hospital público de Lima-Perú, en el periodo 2007 al 2016.

OBJECTIVES: Establish the prevalence of gastric polyps detected by upper gastrointestinal endoscopy in patients older than 18 years old during the period from 2007 - 2016 in Cayetano Heredia Hospital. MATERIALS AND METHODS: Retrospective cross-sectional study, performed with data from the gastric biopsies reports of patients that have undergone upper gastrointestinal endoscopy between January 2007 and July 2016. Demographic data, endoscopic characteristics of the polyps and associated histological changes of the surrounding gastric mucosa were evaluated, which were subjected to statistical analysis using STATA v14.2. RESULTS: In a population of 16 552 endoscopies, 407 gastric polyps biopsies were found. These results give a prevalence of 2.5% .Gastric polyps were detected predominantly in women (62.38%). The median age was 61 years (52-71 years). The most frequent histological type was the fundic gland polyp (FGP) (44.85%), followed by the hyperplastic (38.48%) and adenomatous (15.23%) polyp. The most frequent location was in the fundus / corpus (48.65%, p = 0.001). The presence of Hp was detected in 30.6% of the biopsies with polyps. CONCLUSION: The prevalence of gastric polyps is similar to other regions of the world; PGF and hyperplastic are the most frequent. Adenomatous polyps showed a greater relationship with and metaplasia and dysplasia.

Hypoxic hepatitis in an extensive aortic disecction: case report.

Hypoxic hepatitis is an uncommon cause of hepatic damage characterized by a centrolobular necrosis. Its pathophysiology remains unclear. Aortic dissection is a rare but frequently catastrophic event. It is caused by an aortic intimal tear with propagation of a false channel in the media. Depending on the site and extension, it can cause hypoperfusion of any organ leading to cellular ischemia and necrosis. We are presenting a case of hypoxic hepatitis in a patient with an extensive aortic dissection who present to the emergency department.

Prevalencia de tipos histológicos de pólipos gástricos en pacientes adultos de un hospital público de Lima-Perú, en el periodo 2007 al 2016 / Prevalence of histological types of gastric polyps in adult patients from a public hospital in Lima-Peru (2007 - 2016)

Objetivos: Determinar la prevalencia de pólipos gástricos detectados mediante endoscopía digestiva alta, en pacientes mayores de 18 años del Hospital Cayetano Heredia, en el periodo 2007-2016. Materiales y métodos: Estudio retrospectivo de corte transversal, realizado con datos de biopsias gástricas de pacientes sometidos a endoscopía digestiva alta entre enero de 2007 y julio de 2016. Se evaluó cambios histológicos asociados, datos demográficos y características endoscópicas, las cuales fueron sometidas a análisis estadístico mediante STATA v14.2. Resultados: En una población de 16 552 endoscopías realizadas, se encontró 407 biopsias compatibles con pólipos gástricos, lo cual da una prevalencia de 2,5%. Los pólipos gástricos fueron más frecuentes en mujeres (62,38%). La mediana de edad fue de 61 años (52-71 años). El tipo histológico más frecuente fue el pólipo glandular fúndico (PGF) (44,85%), seguido de pólipo hiperplásico (38,48%) y adenomatoso (15,23%). La localización más frecuente fue en fondo/cuerpo (48,65%, p=0,001) Se detectó la presencia de Helicobacter pylori (Hp) en el 30,6% de las biopsias compatibles con pólipos. Conclusión: La prevalencia de pólipos gástricos es similar con otras regiones del mundo; los PGF e hiperplásicos son los más frecuentes. Los pólipos adenomatosos estuvieron en mayor relación a cambios como metaplasia y displasia.

Objectives: Establish the prevalence of gastric polyps detected by upper gastrointestinal endoscopy in patients older than 18 years old during the period from 2007 - 2016 in Cayetano Heredia Hospital. Materials and methods: Retrospective cross- sectional study, performed with data from the gastric biopsies reports of patients that have undergone upper gastrointestinal endoscopy between January 2007 and July 2016. Demographic data, endoscopic characteristics of the polyps and associated histological changes of the surrounding gastric mucosa were evaluated, which were subjected to statistical analysis using STATA v14.2. Results: In a population of 16 552 endoscopies, 407 gastric polyps biopsies were found. These results give a prevalence of 2.5% .Gastric polyps were detected predominantly in women (62.38%). The median age was 61 years (52-71 years). The most frequent histological type was the fundic gland polyp (FGP) (44.85%), followed by the hyperplastic (38.48%) and adenomatous (15.23%) polyp. The most frequent location was in the fundus / corpus (48.65%, p = 0.001). The presence of Hp was detected in 30.6% of the biopsies with polyps. Conclusion: The prevalence of gastric polyps is similar to other regions of the world; PGF and hyperplastic are the most frequent. Adenomatous polyps showed a greater relationship with and metaplasia and dysplasia.

Hypoxic hepatitis in an extensive aortic disecction: case report / Hepatitis hipóxica en una disección aórtica extensa: reporte de caso

Hypoxic hepatitis is an uncommon cause of hepatic damage characterized by a centrolobular necrosis. Its pathophysiology remains unclear. Aortic dissection is a rare but frequently catastrophic event. It is caused by an aortic intimal tear with propagation of a false channel in the media. Depending on the site and extension, it can cause hypoperfusion of any organ leading to cellular ischemia and necrosis. We are presenting a case of hypoxic hepatitis in a patient with an extensive aortic dissection who present to the emergency department.

La hepatitis hipóxica es una causa poco frecuente de daño hepático caracterizada por una necrosis centrolobular. Su fisiopatología sigue siendo poco clara. La disección aórtica es un evento raro pero con frecuencia catastrófico. Dependiendo del sitio y la extensión, puede causar hipoperfusión de cualquier órgano lo que conduce a una isquemia celular y necrosis. Nosotros presentamos un caso de hepatitis hipóxica en un paciente con disección aórtica extensa que se presenta al servicio de emergencia.

[Fulminating ischemic hepatitis induced by severe cardiac dysfunction: case report]. / Hepatitis isquémica fulminante inducida por disfunción cardiaca severa: reporte de caso.

Ischemic Hepatitis is an uncommon entity in daily clinical practice with a prevalence of 0.16 to 0.5% among patients admitted to a critical care unit, associated with an approximate 60% mortality rate. This liver disease is characterized by a rapid and marked increase (more than 20 times the normal value) of the level of transaminases secondary to a severe and persistent hepatic hypoperfusion caused by multiple etiologies, which may be transient when the triggering cause is timely identified and appropiately treated. The case of an elderly adult patient with a clinical, epidemiological and biochemical profile compatible with ischemic hepatitis secondary to severe cardiac dysfunction is presented below.
