Endoscopic ultrasound(EUS)with fine needle aspiration or fine needle biopsy is the gold standard for sampling tissue to diagnose pancreatic cancer and auto-immune pancreatitis or to analyze cyst *** most common reported adverse event of fine needle aspiration and/or fine needle biopsy is acute pancreatitis,which is likely induced by the same pathophysiological mechanisms as after en-doscopic retrograde cholangiopancreatography(ERCP).According to the current European Society of Gastrointestinal Endoscopy guideline,nonsteroidal anti-inflammatory drugs are administered prior to ERCP as a scientifically proven treatment to reduce post-ERCP pancreatitis incidence rate.A single suppository of diclofenac or indomethacin prior to EUS guided tissue acquisition(TA)is harm-less in healthy *** it is associated with low costs and,most important,may prevent a dreadsome complication,we strongly recommend the adminis-tration of 100 mg diclofenac rectally prior to *** will explain this recom-mendation in more detail in this review as well as the risk and pathophysiology of post-EUS TA pancreatitis.
