Non-invasive diagnosis and grading of postsurgical endoscopic recurrence in Crohn's disease
2010
Abstract Non-invasive techniques aim to be an alternative to endoscopy in the assessment of postsurgical recurrence of Crohn's disease (CD). The object of this study was to evaluate the accuracy of abdominal ultrasonography (AUS) and 99m Tc-hexamethylpropylene amineoxime ( 99m Tc-HMPAO)-labelled leucocyte scintigraphy (LLS) compared with endoscopy in the diagnosis and grading of postsurgical recurrence of CD. Between January 2006 and May 2007, all patients with CD and resection with ileocolic anastomosis were included prospectively. Within three days they underwent an ileocolonoscopy, AUS with evaluation of bowel wall thickness and the presence of Doppler flow, and LLS. Forty patients who m…

Contrast-enhanced ultrasonography: usefulness in the assessment of postoperative recurrence of Crohn's disease.
2013
Abstract Aim The aim of this study was to assess whether the contrast-enhanced ultrasonography (CEUS) can increase the value of the ultrasonography in the study of postoperative recurrence of Crohn's disease (CD). Materials and methods 60 patients with CD who had previously undergone ileocolic resection underwent prospectively both CEUS and colonoscopy within a 3-day period. The sonographic examination included evaluation of bowel wall thickness, transmural complications, colour Doppler grade and contrast-enhanced US. In addition a sonographic score was established. The capacity of CEUS to diagnose endoscopic recurrence, as well as its severity, was assessed by calculating the sensitivity, …

Role of the gastroenterologist in the management of the obese patient.
2017
Obesity is a highly prevalent disease worldwide, and one in which gastroenterologists can play an important role. Some digestive diseases are more common in obese patients, and preoperative evaluation may be required in some cases. Additionally, bariatric surgery can lead to digestive complications in the short and long term that require intervention, and endoscopic treatment can be an important factor in weight loss. The aim of this review is to highlight the role of the gastroenterologist in the management of obese patients who are either scheduled for or have undergone surgical or endoscopic treatment for obesity.

Hemocromatosis: etiopatogenia, diagnóstico y estrategia terapéutica
2012
Resumen La hemocromatosis hereditaria (HH) engloba varios trastornos hereditarios caracterizados por un aumento de la absorcion intestinal de hierro, y una acumulacion posterior en los tejidos. La mayoria de los pacientes (aproximadamente el 90%) con HH tienen mutaciones en el gen HFE . Aproximadamente el 95% de las personas con HH con mutacion HFE son homocigotos para la mutacion C282Y. Estudios poblacionales indican que la mutacion C282Y tiene una penetrancia incompleta. Las mutaciones en los genes relacionados con el hierro que codifican la hemojuvelina, hepcidina, ferroportina, receptor de transferrina 2 y la ferritina constituyen las HH no relacionadas con el gen HFE . En HH-HFE el exc…

Ser y no ser del síndrome del instestino irritable
2001
El esfuerzo para desarrollar un sistema de definicion del sindrome del intestino irritable (SII) se justifica por la necesidad de disponer de una base que permita el logro de dos objetivos relevantes: efectuar un diagnostico positivo del sindrome y optimar su investigacion clinica. La importancia del primer objetivo es obvia si se considera que el SII es un trastorno de elevada prevalencia que, como muchos otros trastornos funcionales digestivos, carece de marcadores objetivos que lo caractericen; el no disponer de una prueba diagnostica definitiva determina, tanto en el medico como en el paciente, un elevado grado de incertidumbre y frustracion que frecuentemente lleva al clinico a solicit…
99mTc-Hexamethylpropylene Amineoxime Leukocyte Scintigraphy in Acute Pancreatitis: An Alternative to Contrast-Enhanced Computed Tomography?
2005
Contrast-enhanced computed tomography (CECT) is the most efficient imaging technique for the diagnosis and staging of acute pancreatitis (AP); its use, however, may be unfeasible in some patients as a consequence of the drawbacks of intravenous (IV) contrast material. The aim of this study was to test the utility of labeled leukocyte scintigraphy (LLS) as an alternative imaging technique to CECT for the staging of AP.Sixty-six patients with AP were prospectively studied. All patients underwent CECT and pancreatic LLS using (99m)Tc-hexamethylpropylene amineoxime as leukocyte label within a time interval of 2 days, in the early phase of AP. In addition, all patients had their serum C-reactive…
Association ofStreptococcus gallolyticussubspeciesgallolyticuswith colorectal cancer: Serological evidence
2015
The colonic opportunist Streptococcus gallolyticus subspecies gallolyticus (SGG) is potentially associated with colorectal cancer (CRC). Large-scale seroepidemiological data for SGG antibodies and their possible association with CRC is currently missing. Associations between CRC and antibody responses to SGG were examined in 576 CRC cases and 576 controls matched by sex, age and province from a population-based multicase-control project (MCC-Spain). MCC-Spain was conducted between 2008 and 2013 in 12 Spanish provinces. Antibody responses to recombinant affinity-purified SGG pilus proteins Gallo1569, 2039, 2178 and 2179 were analysed by multiplex serology. Polyomavirus (PyV) JC VP1 and PyV 6…
Patología articular en la enfermedad inflamatoria intestinal
2005
The joint disorders taxonomically included in the group of seronegative spondyloarthropathies under the generic name of enteropathic arthropathy represent the most frequent extra-intestinal manifestation of inflammatory bowel disease (IBD), affecting 33% of patients. Their frequency is similar to that of ulcerative colitis and Crohn's disease. Enteropathic arthropathy consists of two main joint alterations, peripheral and axial arthritis, as well as a variable group of other peri-articular disorders. Type 1, or pauciarticular, peripheral arthritis generally coincides with IBD exacerbations, while type 2, or polyarticular, peripheral arthritis follows an independent course from IBD. Axial in…

Protocolo diagnóstico de sospecha de alteración del metabolismo férrico en el adulto
2012
Resumen El hierro es un metal esencial para la vida, pero en cantidades elevadas resulta toxico. Las alteraciones del metabolismo del hierro pueden consistir tanto en sindromes que cursan con sobrecarga ferrica, destacando entre ellos la hemocromatosis hereditaria, como en estados deficitarios, representando la anemia ferropenica un problema de salud publica mundial. La anemia ferropenica se puede deber a perdidas excesivas, a un aumento de las necesidades de hierro o a cuadros de malabsorcion intestinal. Ademas del examen fisico se llega al diagnostico mediante datos de laboratorio, siendo el descenso de la ferritina y del indice de saturacion de transferrina los marcadores especificos de …
