LPS tolerance induces a state of altered responsiveness in macrophages, resulting in repression of proinflammatory gene expression and increased expression of factors that mediate the re... |
CONTEXT |
When assessing the bilio-pancreatic region, collating the findings of serum CA 19-9 values together with findings from various imaging tests--especially endoscopic ultrasonography--is not a simple issue in daily clinical practice. |
AIM |
To assess the usefulness of endoscopic ultrasonography in an Endoscopic Ultrasonography Unit in two situations: patients with asymptomatic elevation of serum CA 19-9 and patients who presented with abdominal pain plus elevation of CA 19-9. |
METHODS |
A retrospective study of those patients who underwent radial endoscopic ultrasonography between October 2004 and September 2005 in our institution, considering an elevation of CA 19-9 (equal to or greater than 37 U/mL) with or without symptoms. In each case, the parameters recorded were: levels of CA 19-9 one week befo... |
RESULTS |
Asymptomatic elevation of CA 19-9 was found in 15 patients while 7 patients had elevated CA 19-9 levels as well as pain of uncertain origin. The results of EUS in the asymptomatic patients were: chronic pancreatitis in 7 patients, no pancreatic alterations in 3 patients, and renal cysts, choledocholithiasis, microlithi... |
CONCLUSIONS |
When EUS was indicated for the asymptomatic elevation of CA 19-9, the main findings were benign diseases. EUS was useful in studying patients with idiopathic abdominal pain and a slight elevation of CA 19-9 since it allowed us to detect chronic pancreatitis and even early adenocarcinoma of the pancreatic tail.Student j... |
