Is irregular narrowing of the main pancreatic duct in association with a wall thickening a key sign at endoscopic ultrasonography for the diagnosis of autoimmune pancreatitis?
An irregular narrowing of the main pancreatic duct in association with a wall thickening seen at endoscopic ultrasonography is accurate in diagnosing AIP. The type of echogenicity of the thickening is well correlated with the type of AIP.
Both attachment systems showed decreased retentive forces after 5,000 insertion-separation cycles. However, after 5,000 insertion-separation cycles, locator attachments showed better retentive properties than ball attachments.
