Normal Pancreatic Tissue clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Quantitative And Qualitative Eus Elastography

Start date: October 2013
Phase: N/A
Study type: Observational

Endoscopic ultrasonography is considered the most accurate methods for the diagnosis and staging of chronic inflammatory and neoplastic pancreatic diseases. Differential diagnosis of solid pancreatic masses, however, remains a challenge and endoscopic ultrasound-guided fine needle aspiration is necessary. Recently, Endoscopic ultrasound elastography has been introduced as an alternative method to evaluate tissue stiffness of solid pancreatic masses, being an index of tissue elasticity, which may be related to histopathology features (hard tissue = blue = neoplastic and soft tissue = red-yellow-green = non-neoplastic). However, recently publications show different results using elastography. Moreover, a lack of data in Endoscopic ultrasound-elastography exist regarding the compression rate of the probe and the diameter of the region of interest under analysis in previously studies that by physics could affect the tissue elasticity. Based on the hypothesis that elastography could be affected by compression rate of the probe and the diameter of the region of interest analyzed the present study aimed to evaluate the quantitative (strain ratio) and qualitative endoscopic ultrasound-elastography results determined by the compression rate of the probe (measured by the curve of compression in the second generation of elastography) and the diameter of the region of interest in normal pancreatic tissue.
