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, …

Usefulness of abdominal ultrasonography in the analysis of endoscopic activity in patients with Crohn's disease: changes following treatment with imm…

2013

The objective of this study was to analyze the accuracy of abdominal ultrasonography (AUS) in the assessment of mucosal healing in patients with Crohn's disease (CD) receiving immunomodulators and/or biological treatment, with ileocolonoscopy as the reference standard.Thirty patients were included in a prospective longitudinal study. All patients underwent ileocolonoscopy and AUS before and after a minimum of one year of treatment. The Crohn's Disease Endoscopic Inflammatory Index of Severity (CDEIS) was used for endoscopic assessment whereas AUS was analyzed by means of bowel wall thickness, color Doppler grade and percentage of increase of parietal enhancement after contrast injection.In …

Valor de la proteína C reactiva en la detección de la necrosis en la pancreatitis aguda

2003

Objetivos Valorar la utilidad de la proteina C reactiva (PCR) en la deteccion de la necrosis en la pancreatitis aguda y precisar el mejor nivel de corte de la PCR para esta finalidad. Material y metodos Se incluyeron, de forma retrospectiva, 157 pacientes con pancreatitis aguda a los que se habia efectuado una tomografia computarizada (TC) con contraste intravenoso, entre las 72 h y el octavo dia del inicio de la sintomatologia, y determinado el valor de la PCR en el suero por nefelometria a partir de las 24 h del comienzo del dolor. Resultados En total, fueron incluidos 94 varones y 63 mujeres, con una media de edad de 61 anos (limites, 15-96 anos). La etiologia de la pancreatitis fue: lit…

Pancreas and Cystic Fibrosis: The Implications of Increased Survival in Cystic Fibrosis

2007

Background: In acute pancreatitis (AP), pancreatic necrosis (PN) is an important local complication that can be identified by means of contrast-enhanced computed tomography (CECT).

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…
