Article Synopsis
- A study was conducted in Japan to validate the effectiveness of urinary trypsinogen-2 dipstick tests and other related markers in diagnosing acute pancreatitis.
- The research involved 94 patients and assessed the sensitivity and specificity of these markers alongside CT imaging criteria.
- The results confirmed that the urinary trypsinogen-2 dipstick test is a reliable diagnostic tool, and both urinary trypsinogen-2 and TAP levels can indicate the presence of inflammation outside the pancreas.
Objective: Corticosteroid has been established as the standard therapy for autoimmune pancreatitis (AIP), but the requirement for maintenance corticosteroid therapy is controversial. We conducted a randomised controlled trial to clarify the efficacy of maintenance corticosteroid therapy in patients with AIP.
Design: We conducted a multicentre, tertiary setting, randomised controlled trial.
Objective: The aim of the study was to clarify clinicopathological features of type 2 autoimmune pancreatitis (AIP) in Japan; a multicenter survey was carried out.
Methods: The first screening collected patients with pancreatitis whose pancreatic tissue samples were available and who fulfilled at least 1 of the following 3 criteria as possible type 2 AIP: (1) histological presence of granulocytic epithelial lesion, (2) age of 50 years or younger, and (3) association of ulcerative colitis, Sjogren syndrome, and/or primary biliary cirrhosis. Patients with histologically confirmed type 1 AIP were also collected as a control.
Objectives: To clarify the clinicoepidemiological features of autoimmune pancreatitis (AIP) in Japan, a nationwide epidemiological survey was conducted.
Methods: Patients with AIP who had visited selected hospitals in 2011 were surveyed. Autoimmune pancreatitis was diagnosed according to the revised clinical diagnostic criteria for AIP (Japan Pancreas Society 2011).
A 65-year-old man presented with upper abdominal pain and was suspected of having choledocholithiasis. Endoscopic extraction of the stone was performed; however, a round filling defect in the common bile duct (CBD) persisted. Subsequent cholangioscopy showed the presence of a papillary tumor in the CBD, and the lesion was removed via the Whipple procedure.
