Carcinoma neuroendocrino de colon poco diferenciado con metástasis hepáticas / Poorly differentiated neuroendocrine carcinoma of the colon with liver metastases

Resumen Los tumores neuroendocrinos del tubo digestivo son lesiones muy poco frecuentes. Se presenta el caso de una mujer de 57 años de edad que consulta por síndrome tóxico, vómitos y diarrea de 3 meses de evolución, con diagnóstico final de tumor neuroendocrino pobremente diferenciado. A partir de esta observación clínica se revisan las características clínicas y procedimientos diagnósticos, los factores pronósticos y las posibilidades terapéuticas en este tipo de tumores. Ante una tumoración colónica con metástasis hepáticas hiperecogénicas se debe considerar siempre el diagnóstico de tumor neuroendocrino (AU)

Abstract Neuroendocrine tumors of the gastrointestinal tract are highly infrequent. We report the case of a 57-year-old woman who presented with toxic syndrome, vomiting and a 3-month history diarrhea, with a final diagnosis of poorly-differentiated neuroendocrine tumor. Based on this case, we review the clinical characteristics, diagnostic procedures, prognostic factors and therapeutic possibilities in this type of tumor. Neuroendocrine tumors should be considered in the diagnosis of colonic tumors with hyperechoic liver metastases (AU)

Asistencia urgente a los pacientes con hemorragia digestiva alta en los hospitales comarcales catalanes / Emergency care of patients with upper gastrointestinal bleeding in regional hospitals in Catalonia

Objetivo Valorar los recursos disponibles en los hospitales comarcales catalanes para la asistencia urgente de la hemorragia digestiva alta. Método Se analiza una encuesta enviada a 32 hospitales, sobre la existencia, composición y recursos del turno de guardia (TDG) de endoscopia, referida al año 2009.ResultadosRespondieron 24 centros, que cubrían la asistencia de 3.954.000 habitantes. Tenían TDG 12 hospitales. No disponían de TDG en su centro de referencia 1.483.000 habitantes. Los centros con TDG tenían más camas y cubrían más población. Los TDG estaban formados por 4,5 endoscopistas (rango 2-11), que cubrían 82,1 (33,2-182,5) guardias/año. Diecisiete centros reportaban 1.571 episodios (51 por centro, rango 3-280, 39,68/100.000 hab.). Los centros con TDG reportaban más casos (76 vs. 43, p=0,047). Los que no disponen de TDG derivaron más pacientes (147 vs. 17, p= 0,001). Los pacientes en urgencias estaban a cargo de medicina interna en 4 centros, de cirugía en 14 y repartidos entre ambos servicios en 6. Si ingresaban, quedaron a cargo de Digestivo solo en 6 hospitales. Los recursos más utilizados eran la ligadura en la hemorragia varicosa y las terapias de inyección en la no varicosa. Un 21% de centros no realizaban tratamiento combinado. Conclusiones Una proporción significativa de la población no dispone de endoscopista de guardia en su centro de referencia. La constitución de TDG en hospitales comarcales supone importantes cargas asistenciales. La coordinación entre profesionales y centros permitiría la aplicación eficiente de los recursos terapéuticos y el establecimiento de TDG en centros que no tienen (AU)

Objective To evaluate the resources available in Catalan regional hospitals for the emergency care of upper gastrointestinal hemorrhage. Methods We analyzed a survey sent to 32 hospitals on the availability, composition and resources of a duty endoscopy service for the year 2009.ResultsResponses were obtained from 24 centers, covering 3,954,000 inhabitants. Duty endoscopists were available in 12 hospitals. A total of 1,483,000 inhabitants were unable to access a duty endoscopist in the referral center. Centers with duty endoscopists had more beds and had a larger catchment area. Duty services were composed of 4.5 endoscopists (range 2-11), covering 82.1 (33.2-182.5) duty shifts/year. Seventeen centers reported 1,571 episodes (51%, range: 3-280, 39.68/100,000 inhabitants). Centers with a duty service reported a greater number of cases (76 vs. 43, p=0.047). Centers without this service referred a greater number of patients (147 vs. 17, p=0.001). Patients in the emergency department were under the care of the internal medicine department in four centers, the surgery department in 14 centers and under the care of both departments in six. Admitted patients were under the care of the gastroenterology department in only six hospitals. The most widely used procedures were ligation of varicose bleeding and injection therapies in non-varicose bleeding. Twenty-one percent of centers did not perform combined treatment. Conclusions A significant proportion of the population does not have access to a duty endoscopist in referral centers. Duty shifts represent significant workload in regional hospitals. Coordination among health professionals and centers would allow the efficient application of therapeutic resources and a duty endoscopy service to be established in centers lacking this resource (AU)

A survey of gastroenterologists and general practitioners

Fundamento y objetivoLa colaboración entre médicos de familia (MF) y especialistas se considera indispensable para una asistencia sanitaria de calidad. El objetivo del presente estudio es analizar la relación entre los gastroenterólogos (GAS) y los MF en el ámbito de los hospitales comarcales de Cataluña y sus centros de atención primaria de referencia.Material y métodosEstudio descriptivo, observacional y transversal, realizado mediante cuestionario anónimo entre los meses de enero y abril de 2008.ResultadosSe recogieron 314 encuestas (261 MF y 53 GAS). La valoración global de la relación se consideró muy deficiente o insuficiente por el 62,3% de los GAS (IC95%, 47,9–74,9) y por el 55,6% de MF (IC95%, 49,3–61,7). El 56,6% de GAS no conoce o conoce a pocos MF y lo mismo sucede con el 80,4% de MF. El 64% de GAS considera que la calidad asistencial para la patología digestiva en AP es muy deficiente o insuficiente. Por su parte, el 21,1% de MF considera muy deficiente o insuficiente la calidad asistencial por parte de GAS. La percepción de la calidad de la asistencia tanto en atención especializada como en AP mejora significativamente cuando el grado de conocimiento personal entre GAS y MF es alto o muy alto.ConclusionesLos profesionales perciben como insuficiente el nivel de relación entre niveles asistenciales. Además, los GAS evalúan como deficiente el manejo de la patología digestiva en atención primaria. La existencia de una relación personal mejora significativamente la valoración mutua (AU)

Background and objectivesCollaboration between general practitioners (GPs) and specialists is considered crucial to provide high-quality healthcare. The objective of this study was to analyze the relationship between gastroenterologists and GPs in regional hospitals and their referring primary care centers in Catalonia (Spain).Materials and methodsA descriptive, observational, cross-sectional study was carried out using anonymous questionnaires between January and April 2008.ResultsA total of 314 surveys were administered (261 GPs and 53 gastroenterologists). The overall relationship was considered highly deficient or insufficient by 62.3% of gastroenterologists (95% CI, 47.9–74.9) and by 55.6% of GPs (95% CI, 49.3–61.7). More than half (56.6%) of the gastroenterologists did not know any GPs, or only a very few, and the situation was the same for 80.4% of GPs. Sixty-four percent of gastroenterologists considered that the quality of care for digestive diseases in primary care was highly deficient or insufficient while 21.1% of GPs considered that the care provided by gastroenterologists was highly deficient or insufficient. The perception of healthcare in both primary and specialized settings was substantially better when there was good interaction between gastroenterologists and GPs.ConclusionsPractitioners acknowledge that the degree of interaction between different levels of healthcare is insufficient. Moreover, gastroenterologists consider that the management of digestive diseases in primary care is deficient. Establishing a personal relationship between the two types of practitioners substantially improves mutual assessment (AU)

Prevalence and factors related to hepatitis B and C in inflammatory bowel disease patients in Spain: a nationwide, multicenter study.

OBJECTIVES: Limited information suggests the existence of a high prevalence of hepatitis B (HBV) and C virus (HCV) infection in inflammatory bowel disease (IBD). This knowledge is relevant because the viruses may reactivate under immunosuppressive therapy. The objectives of this study are to assess the prevalence of HBV and HCV infection in IBD, in a nationwide study, and to evaluate associated risk factors. METHODS: This cross-sectional multicenter study included 2,076 IBD patients, consecutively recruited in 17 Spanish hospitals. Factors related to IBD (severity, invasive procedures, etc.) and to infection (transfusions, drug abuse, etc.) were registered. Independent risk factors for viral infection were evaluated using logistic regression analysis. RESULTS: Present and/or past HBV and HCV infection was found in 9.7% of patients of both ulcerative colitis (UC) and Crohn's disease (CD) (UC: HBsAg 0.8%, anti-HBc 8%, anti-HCV 1.3%; CD: HBsAg 0.6%, anti-HBc 7.1%, anti-HCV 2.3 %). Effective vaccination (anti-HBs, without anti-HBc) was present in 12% of patients. In multivariate analysis, age (odds ratio (OR) 1.04; 95% confidence interval (CI) 1.02-1.06; P=0.000), family history of hepatitis (OR 2.48; 95% CI 1.3-4.74; P=0.006) and moderate-to-severe IBD disease (OR 2.5; 95% CI 1.02-6.15; P=0.046) were significantly related to HBV, whereas transfusions (OR 2.66; 95% CI 1.2-5.87; P=0.015) and antibiotic use (OR 2.66; 95% CI 1.1-6.3; P=0.03) were significantly related to HCV. The significance for transfusions was lost if they were administered after 1991, when HCV markers became mandatory in blood banks. CONCLUSIONS: Prevalence of HBV and HCV infection in IBD is similar to that of the general population of reference and lower than that in previously published series. This fact, in addition to the lack of association with invasive procedures, suggests the existence of adequate preventive measures in centers attending to these patients. The low percentage of effective vaccination makes it mandatory to intensify B virus vaccination in IBD.

Cost-effectiveness of a 'score and scope' strategy for the management of dyspepsia.

OBJECTIVE: It is important to identify the best initial work-up in patients with uninvestigated dyspepsia because of its epidemiological and economical relevance. The objective of the study was to assess systematically the effectiveness and cost-effectiveness of invasive and non-invasive strategies for the management of dyspepsia. METHODS: A decision analysis was performed to compare prompt endoscopy, score and scope, test and scope, test and treat, and empirical antisecretory treatment. Published and local data on the prevalence of different diagnoses, rates of Helicobacter pylori infection, accuracy values of diagnostic tests, and effectiveness of drug treatments were used. The perspective of analysis was that of the public healthcare payer, and only direct costs were included, with a one-year post-therapy time horizon. The main outcome measure was cost per asymptomatic patient, valued in 2003 Euros. RESULTS: Endoscopy was found to be the most effective strategy for the management of dyspepsia (38.4% asymptomatic patients), followed by test and scope (35.5%), test and treat (35.3%), score and scope (34.7%), and empirical treatment (28.5%). Incremental cost-effectiveness ratios showed that score and scope was the most cost-effective alternative (483.17 Euros per asymptomatic patient), followed by prompt endoscopy (1396.85 Euros). Sensitivity analyses showed variations when varying the values of prevalence of duodenal ulcer, and the values of healing of functional dyspepsia with antisecretory and eradication drugs. There were no changes when varying the prevalence of H. pylori in dyspepsia. CONCLUSIONS: We would recommend stratifying patients by a score system, referring first to endoscopy those patients at higher risk of organic dyspepsia.

[Prospective validation of a clinical scoring system for the diagnosis of organic dyspepsia]. / Estudio prospectivo de un modelo clínico predictivo de dispepsia orgánica.

BACKGROUND AND OBJECTIVE: Predictive symptomatic scoring models have been proposed to select patients with dyspepsia, who may be candidates to endoscopy. In a previous study performed by gastroentrologists from our group, we obtained three scales of symptoms to predict organic dyspepsia, peptic ulcer and esophagitis, respectively. Here we analyze the reproducibility of those scoring models of symptoms when used either by other gastroenterologists or general practitioners. PATIENTS AND METHOD: It was a clinical prospective study of 230 patients from the Viladecans hospital area (120 from primary healthcare and 110 from the gastroenterologist's consultation). The three validation scales were performed in each patient. Then, we performed a diagnostic gastroscopy which allowed to classify patients into those with organic dyspepsia (ulcer, esophagitis, cancer) or those with functional dyspepsia. We calculated the overall predictive accuracy for the gastroenterologist and the general practitioner and for the three diagnoses (organic dyspepsia, ulcer or esophagitis) using the C statistic. RESULTS: Discriminative capacities were 0.75 and 0.82 for organic dyspepsia, 0.78 and 0.86 for ulcer disease, and 0.78 and 0.82 for esophagitis, for the general practitioner and the gastroenterologist, respectively. In this validation study, the best cut-off value, namely the one combining good sensitivity and specificity, was found to be 7. CONCLUSIONS: A correct predictive capacity of the symptomatic score models when used by other gastroenterologists or by primary healthcare practioners confirms its reproducibility and transferability. The use of predictive symptomatic score models in everyday clinical practice can allow to rationalize the referral for endoscopy in our local setting.

Estudio prospectivo de un modelo clínico predictivo de dispepsia orgánica / Prospective validation of a clinical scoring system for the diagnosis of organic dyspepsia

FUNDAMENTO Y OBJETIVO: Los modelos predictivos basados en un conjunto de síntomas pueden ser útiles para seleccionar a los pacientes con dispepsia candidatos a endoscopia. Un estudio previo realizado por gastroenterólogos obtuvo tres escalas de síntomas con alto valor predictivo para dispepsia orgánica, úlcera péptica y esofagitis. El objetivo del presente estudio fue validar de forma prospectiva la reproducibilidad de dichos modelos al ser utilizados por médicos de atención primaria o por otros gastroenterólogos. PACIENTES Y MÉTODO: Estudio clínico prospectivo en 230 pacientes del área del hospital de Viladecans (120 de atención primaria y 110 de consulta de gastroenterología) a los que se aplicaron las tres escalas a validar. Posteriormente se realizó una endoscopia que clasificó a los pacientes en dispepsia orgánica (úlcera, esofagitis, cáncer) o funcional. La capacidad discriminante para dispepsia orgánica, úlcera y esofagitis del médico de primaria y del gastroenterólogo al aplicar cada una de las escalas se calculó mediante el estadístico c. RESULTADOS: Las capacidades discriminantes fueron 0,75 y 0,82 para dispepsia orgánica, 0,78 y 0,86 para úlcera, y 0,78 y 0,82 para esofagitis, para médicos de atención primaria y para gastroenterólogos, respectivamente. El punto de corte óptimo para discriminar dispepsia orgánica, el que combina la mayor sensibilidad con la mayor especificidad, subió de 6 a 7 puntos en esta validación con respecto al estudio inicial. CONCLUSIONES: La confirmación de la reproducibilidad y transferibilidad de un modelo predictivo sencillo de dispepsia orgánica abre la posibilidad de utilizar este tipo de instrumentos para conseguir un abordaje más eficiente de la dispepsia (AU)
