| 抄録 | BACKGROUND AND OBJECTIVE:Although EUS is useful for diagnosis of tumors in the pancreas,the EUS findings are not employed in the International criteria for autoimmune pancreatitis(AIP){ICDC2008} and Clinical diagnostic criteria for AIP 2011{CDC2011}. OBJECTIVE:The aim of the study was to investigate the role of EUS in diagnosis and treatment of AIP. METHODS:EUS findings of 21 patients that were diagnosed with AIP using the ICDC2008 and CDC2011 were re-evaluated. EUS findings included the following features ; a:lobularity, b:strands, c:hyperechoic foci, d:duct penetrating sign, e:cupsule like rim, f:mass forming pancreatitis, g:isoenhancement on contrast enhanced EUS. Changes in EUS findings were evaluated 2 months after the steroid therapy.EUS-FNA was performed in all patients. RESULTS EUS findings:a,b,c,d,e,f and g were observed in 81%,100%,100%,86%,48%,80% and 81%,respectively. Other imaging modalities failed to exclude a pancreatic carcinoma in 11 patients with focal type of AIP. However,EUS images and histology obtained by EUS-FNA showed typical findings of AIP in these patients.In 9 patients who received steroid therapy,lobularity and strands disappeared. CONCLUSION: EUS is useful for discrimination of focal AIP from pancreatic carcinoma and evaluation of response to steroid therapy. Strands,lobularity observed by EUS may reflect the disease activity. |
