ABSTRACT

BACKGROUND: endoscopic ultrasonography (EUS) is a high accuracy technique for the study of many digestive diseases. The degree of knowledge about the impact of EUS on the management of these patients is inadequate. AIM: to determine the therapeutic impact of endoscopic ultrasonography (EUS) on a prospective cohort of patients. METHODS: all patients referred for EUS over a period of 2 years were prospectively evaluated in order to asses: 1. EUS provides new information not previously known; 2. theoretic impact of EUS on patient management; 3. real impact of EUS on final therapy; 4. changes in the aggressiveness of the therapeutic decision after EUS. RESULTS: 700 patients were included. Preoperative assessment of digestive tumors was the commonest indication. EUS provided "new information" in the 89% of the patients. With regard to endoscopist opinion, these findings should alter the management in 79% of patients ("theoretic impact"). However, EUS prompted a change in the management in 67% of patients ("real impact"). Final therapy post-EUS was less aggressive in 34% of patients. Changes in therapeutic decision were associated with EUS findings, alcohol intake and age ≥ 57 years old. CONCLUSIONS: 1) EUS findings, advanced age, and alcohol intake are associated with a change in the management in 2 out of every 3 patients referred for EUS. 2) Therapeutic decision (post-EUS) is less aggressive in a third of these patients, what should represent a significant economic saving.

ABSTRACT

Antecedentes: la ultrasonografía endoscópica (USE) es una técnica de gran precisión para el estudio de diferentes patologías digestivas. El grado de conocimiento sobre el impacto de la USE en el tratamiento de estos pacientes es escaso. Objetivo: determinar el impacto terapéutico de la USE en una cohorte prospectiva de pacientes. Material y métodos: estudio que evalúa de forma prospectiva a todos los pacientes remitidos para USE en un periodo de 2 años. Se analiza: a) si la USE aporta información no conocida previamente; b) el impacto teórico de la USE en el tratamiento; c) el impacto final/real de USE en el tratamiento; d) la variación en la decisión terapéutica tras realizar la USE. Resultados: se incluyeron 700 pacientes. La indicación más frecuente de USE era el estudio preoperatorio de tumores digestivos. La USE aportó “información nueva” en el 89% de los casos. En opinión del ecoendoscopista estos hallazgos deberían suponer un cambio terapéutico en el 79% de los pacientes (“impacto teórico”). Sin embargo, el tratamiento sólo se modificó en el 67% de los casos (“impacto real”). La estrategia terapéutica post-USE fue menos agresiva en el 34% de los casos. Los cambios en la actitud terapéutica se asociaban con los hallazgos de USE, ingesta de alcohol y edad > 57 años. Conclusiones: – Los hallazgos de la USE, la edad avanzada y el consumo de alcohol, se asocian con un cambio terapéutico en 2 de cada 3 pacientes remitidos a una unidad de USE. – La decisión terapéutica final (post-USE) es menos agresiva en un tercio de estos pacientes, lo que podría representar un ahorro económico significativo(AU)

ABSTRACT

OBJECTIVE: To study the accuracy of four currently used tests for the diagnostic of Helicobacter pylori infection among gastric ulcer patients with a gold standard as reference which combines several diagnostic methods. MATERIAL AND METHODS: Seventy-three consecutive gastric ulcer patients were prospectively studied. From all patients, three biopsies each were obtained from both antrum and body (two for haematoxylin-eosin staining and one for rapid urease test--Jatrox H.p. Test--. Also, IgG ELISA serology (Helico G) and 13C-urea breath test were performed. According to the gold standard, a patient was considered to be infected with H. pylori when at least two tests were positive; a patient was considered not to be infected with H. pylori when at least three tests were negative. RESULTS: Among gastric ulcer patients, the prevalence of H. pylori infection was 87.6% (95% CI: 78%-93%) with the gold standard as reference. The sensitivity and specificity values were as follows: histology (antrum), 96.8% (89%-99%) and 100% (66%-100%), respectively; histology (body), 98.4% (91%-100%) and 100% (66%-100%); urease test (antrum), 71.8% (60%-81%) and 100% (66%-100%); urease test (body), 96.8% (89%-99%) and 100% (66%-100%); breath test, 100% (94%-100%) and 100% (66%-100%), and serology, 95.3% (87%-98%) and 100% (66%-100%). The sensitivity of the urease test was higher with a body biopsy specimen (McNemar: 15; p < 0.001). CONCLUSIONS: All diagnostic tests (histology, rapid urease test, 13C-urea breath test and serology) are highly accurate for the diagnosis of H. pylori infection among gastric ulcer patients with the exception of the rapid urease test performed with antrum biopsy specimens, where this test displays a lower sensitivity for bacterial detection.

ABSTRACT

Objetivo. Estudiar en enfermos con úlcera gástrica la eficacia de cuatro métodos diagnósticos de la infección por Helicobacter pylori de amplio uso en la actualidad, utilizando para ello un 'patrón oro' que combina varias técnicas diagnósticas. Material y métodos. Se estudiaron prospectivamente 73 ulcerosos gástricos consecutivos. En todos los pacientes se obtuvieron tres biopsias del antro y tres del cuerpo (dos para tinción de hematoxilina-eosina y una para la prueba rápida de la ureasa -Jatrox H.p.Test-). Asimismo se realizó una serología ELISA IgG (Helico G) y una prueba del aliento con urea-C13.Según el patrón oro, un paciente estaba infectado cuando dos o más técnicas eran positivas; se consideró ausencia de infección la negatividad de al menos tres de los métodos diagnósticos utilizados. Resultados. La prevalencia de la infección por H. pylori en los pacientes con úlcera gástrica tomando como referencia el patrón oro fue del 87,6 por ciento (IC 95 por ciento: 78 por ciento-93 por ciento). La sensibilidad y especificidad de los métodos diagnósticos fueron las siguientes: histología (antro), 96,8 por ciento (89 por ciento-99 por ciento) y 100 por ciento (66 por ciento-100 por ciento), respectivamente; histología (cuerpo), 98,4 por ciento (91 por ciento-100 por ciento) y 100 por ciento (66 por ciento-100 por ciento); prueba de la ureasa (antro), 71,8 por ciento (60 por ciento-81 por ciento) y 100 por ciento (66 por ciento-100 por ciento); prueba de la ureasa (cuerpo), 96,8 por ciento (89 por ciento-99 por ciento) y 100 por ciento (66 por ciento-100 por ciento); prueba del aliento, 100 por ciento (94 por ciento-100 por ciento) y 100 por ciento (66 por ciento-100 por ciento), y serología, 95,3 por ciento (87 por ciento-98 por ciento) y 100 por ciento (66 por ciento-100 por ciento). La sensibilidad de la prueba de la ureasa fue mayor en el cuerpo gástrico (McNemar: 15; p < 0,001).Conclusiones. Los métodos diagnósticos evaluados (histología, prueba rápida de la ureasa, prueba del aliento con urea-C13 y serología) tienen una elevada eficacia para el diagnóstico de la infección por H. pylori en los pacientes con úlcera gástrica, con la excepción de la prueba rápida de la ureasa realizada en muestras del antro, donde esta técnica es menos sensible para la detección de la bacteria (AU)

ABSTRACT

A case of undiagnosed celiac disease associated with macrolipasemia and macroamylasemia is reported. This association is almost unique. To our knowledge, only one case has been previously diagnosed. Previous case reports about macroamylasemia and celiac disease, as well as macrolipasemia, are briefly discussed.
