Background: Chronic pancreatitis (CP) is a fibro-inflammatory disease of the pancreas. Early diagnosis and intervention, before CP becomes established and irreversible, are essential to improve the long-term outcomes. The world's first diagnostic criteria for early CP were proposed in Japan in 2009, but their clinical utility remains elusive.

A 43-year-old woman presented with severe diarrhea and vomiting in addition to abdominal distension and dysphagia which had persisted for a month. Endoscopic biopsies revealed a significant eosinophilic infiltration in the mucosal layer of the esophagus, duodenum and ileum, yielding a diagnosis of eosinophilic gastroenteritis (EG) with esophageal involvement. The endoscopic examination of esophageal lesion in this case showed linear fissures and concentric rings, both of which are characteristic findings observed in eosinophilic esophagitis (EE).

In the blood, 6-thioguanine (6-TGN) is formed from 6-MP and mediates the therapeutic efficacy and most of the toxicities of 6-MP. The level of 6-TGN depends on the activity of thiopurine methyltransferase (TPMT), inherited as 1 of its 3 polymorphic forms with low, moderate, or normal/high activity.

Methods: Between 1993 and 2007, 262 patients who underwent successful EST for choledocholithiasis were followed up for more than 6 months). Eighteen patients had previously undergone cholecystectomy (Group A), 129 had a calculous gallbladder (GB) and underwent cholecystectomy after EST (Group B), 46 had a calculous GB in situ (Group C), and 69 had an acalculous GB in situ (Group D).

A 77-year-old woman underwent abdominal ultrasonic diagnosis in a screening test for diabetes mellitus. A 65 x 45 mm tumor with low echo level was revealed and located from the uncinate process of the pancreas to the body. Contrast-enhanced computed tomography demonstrated the pancreas had a low density area in the arterial phase and a comparable area in the equilibrium phase, compared with the parenchyma of the normal pancreas.

With the cumulative increase in the number of autoimmune pancreatitis cases, the disease is now widely accepted as a symptom of IgG4-related systemic disease. We recently experienced two cases of retroperitoneal fibrosis and Castleman disease presenting high IgG4 levels without evident pancreatic lesions. Both patients were successfully treated with steroid therapy.
