Global research status of gastroenterology and hepatology: A bibliometrics study.

BACKGROUND: There are no reports on global research status of gastroenterology and hepatology (GI). This study was conducted to reveal the current global research status and trends in GI. METHODS: Articles published during 2009 to 2018 in international GI journals were retrieved from the PubMed database. The top 20 countries by output were determined. The gross domestic product (GDP) of each country was also retrieved to figure out the correlation between outputs in GI and economy. The 5 highest-ranking countries were compared in the number of total articles, articles per capita, articles published in top journals, the accumulated impact factor (IF), and average IF. Total articles and articles per capita of the 5 countries were conducted time-trend analysis. The frequently-used terms in titles and abstracts of articles published in 2009 and 2018 were retrieved to conduct co-occurrence analysis to figure out the change of research highlights in GI. RESULTS: A total of 120,267 articles were included, of which 116,485 articles were from 20 highest-output countries. There was a positive correlation between output and GDP (r = 0.921, P < .001). The USA, Japan, China, Italy, and the UK were the 5 highest-ranking countries. The USA was the largest contributor with 26,215 articles, accounting for 17.4% of the total, but with no significant increasing trend (P = .122). Other 4 countries all showed increasing trends (all P < .001). For articles per capita, Italy ranked 1st among the 5 countries with 1591.0 articles per 10 million. The USA showed a decreasing trend (P = .026), other 4 countries all showed increasing trends (all P < .001). The UK had the highest average IF (6.685). For change of research highlights, it is more inclined to research of endoscopy, inflammatory bowel diseases, and nonalcoholic fatty liver disease. CONCLUSION: It is delightful that the global research output in GI field would be continuingly increased as the major highest-output countries showed increasing trends. However, the developing countries fell behind both in quantity and quality when compared with developed countries.

Eficacia de un sistema de consultas de alta resolución en gastroenterología en un centro hospitalario andaluz / Efficacy of a high-resolution consultation system in gastroenterology at an Andalusian hospital center

Antecedentes: la consulta alta resolución o única es aquel proceso asistencial ambulatorio en el que queda establecido un diagnóstico junto con su correspondiente tratamiento y reflejados ambos en un informe clínico, siendo realizadas estas actividades en una sola jornada. Objetivos: conocer en qué grado los pacientes con patología digestiva pueden beneficiarse del sistema de consultas en acto único. Material: estudio descriptivo de 179 episodios de primeras vistas seleccionadas aleatoriamente de una consulta de alta resolución de gastroenterología. Analizamos el porcentaje de pacientes que se beneficiaron de una consulta en acto único así como de las pruebas complementarias realizadas. Resultados: las patologías más frecuentes atendidas fueron la dispepsia (16%), los antecedentes familiares de cáncer de colon (16%) y enfermedad por reflujo gastroesofágico (16%). Setenta y nueve (44%) de las primeras visitas se resolvieron en consulta única y 80 (45%) de una prueba diagnóstica (100% ecografía abdominal) y revisión tras esta en el mismo día. La realización de una prueba en el día incrementaba significativamente el porcentaje de consulta única frente a los que no se les realizaba (57% frente a 34%, p < 0,002). Los pacientes con enfermedad por reflujo gastroesofágico, dispepsia, colelitiasis y hepatopatía crónica eran las patologías que terminaban en mayor porcentaje en consulta única. Conclusiones: las consultas de gastroenterología pueden beneficiarse en gran medida de un sistema de consulta de alta resolución solo con cambios organizativos y sin costes adicionales especiales (AU)

Background: By high resolution consultation (HRC) we mean an ambulatory process of assistance fulfilled in a single day, by which treatment and diagnosis are established and recorded. Objective: To assess to which extent patients with digestive conditions may benefit from a single consultation system. Material: A descriptive study of 179 first visit events, randomly selected as high-resolution consultations in gastroenterology. We discuss the percentage of patients who benefited from HRC and the complementary tests performed. Results: Most common conditions included dyspepsia (16%), a family history of colon cancer (16%) and gastroesophageal reflux disease (GERD) (16%). Seventy-nine (44%) of all first visits became HRCs and 80 (45%) required a diagnostic test (100% abdominal ultrasound) that was reviewed on the same day. Performing a test on the same day significantly increased the percentage of HRCs (57% vs. 34%, p < 0.002). GERD, dyspepsia, cholelithiasis and chronic liver disease were the subjects most commonly leading to HRC. Conclusions: Gastroenterology consultations may largely benefit from an HRC system with only organizational changes and no additional costs (AU)

The Agency is classifying the device into class II (special controls) in order to provide a reasonable assurance of safety and effectiveness of the device.

Frequently asked coding questions.

Current Procedural Terminology (CPT) coding is not an exact science. Although the CPT code set was developed to describe clearly and comprehensively services provided by health care professionals, the intended application of individual codes is not always clear. In addition, coding that may be correct in terms of CPT definitions and instructions may contradict instructions from payment policies set by insurers. This article provides answers to the gastroenterologists' most commonly asked questions and provides primary sources for coding and payment policies when possible. Answers to the questions are accurate as of the date of publication but may be subject to change.

Ingestión de cuerpo extraño en niños: revisión de 10 años en el Hospital de Niños "J.M.de los Ríos" / Foreing bodies ingestion in childrens: review of 10 years in the Children's Hospital \"J.M. de los Ríos\"

Se estudiaron 206 niños que presentaban diagnóstico de ingreso de cuerpo extraño, encontrándose que el objeto más frecuentemente ingerido fueron las monedas(88 por ciento de los casos) y que el grupo etario involucrado en la mayoría de los casos lo constituye los niños de 1 a 4 años. El diagnóstico se basa en la clínica como disnea, tos y vómitos, el antecedente de la ingestión y la radiología. La endoscopia digestiva superior sigue siendo el método de tratamiento más adecuado y seguro para la resolución de estos casos y para la verificación posterior de lesiones residuales en la mucosa esofágica. Del estudio se derivan ciertas recomendaciones para evitar estos episodios

Hemorragias gastrointestinal superior / Upper gastrointestinal hemorrhage

La hemorragia gastrointestinal superior definida como la presencia de sangre no oculta originada en alguna parte del tracto digestivo estre el Esófago y el ligamento de Treiz, es un problema comun enla práctica médica y continua siendo un reto diagnóstico, terapeutico y economico. Estimaciones corrientes de su incidencia indican que esta varía entre 50 - 150 episodios de hemorragia por cada 100.000 habitantes, La mortalidad debida a hemorragia del tracto gastrointestinal superior no ha disminuido en los ñultimos cuarenta años y permanece en un rango de 10 a 15 porciento; aún cuando de todos los episodios de hemorragia el 80 al 85 porciento ceden de manera espontane (1), (2), (3), (4), (5), (6), la alta mortalidad permanece constante, no obstante que se han mejorado los procedimientos dignósticos y terapeuticos, probablemete por que en primer lugar, estos episodios de hemorragia ocurren ahora en pacientes de mayor edad y en segundo lugar, los enfermos en estado critico, apdecen seria enfermedades medicas que por si solas tienen una alta mortalidad.
