Non-alcoholic duct-destructive chronic pancreatitis is a new entity that differs morphologically and pathogenetically from alcoholic chronic pancreatitis. Some clinical and imaging features of this entity resemble those of pancreatic cancer, and hence most of the reported cases underwent pancreatic resections including an invasive pancreaticoduodenectomy. Recognition of this new entity before a definitive treatment is therefore important to avoid an unnecessary pancreatic resection. Recently, we experienced a case of non-alcoholic duct-destructive chronic pancreatitis in an 80-year-old man presenting with obstructive jaundice and whose radiologic features were characteristic as originally described. Recognition of this new entity before definitive treatment enabled us to manage this patient optimally. In addition, the relation between non-alcoholic duct-destructive chronic pancreatitis and chronic pancreatitis with diffuse irregular narrowing of the main pancreatic duct is discussed.

Autoimmune pancreatitis(AIP)is radiologically characterized by sausage-like diffuse swelling of the pancreatic parenchyma but may also be found as a localized mass that is easily misdiagnosed as a pancreatic neoplasm.AIP presenting as multifocal masses is rare.Here we report a case of multifocal IgG4-related AIP,in which the lesions grew in size and finally fused to become radiologically typical.

BACKGROUND/AIMS: Autoimmune pancreatitis is a distinctive type of chronic pancreatitis with reversibility. We analyzed the largest number of patients with autoimmune pancreatitis among the studies carried out at a single institution in Korea. METHODS: We retrospectively analyzed the clinical, radiologic, laboratory and histologic features in 17 patients who were diagnosed as autoimmune pancreatitis. RESULTS: The patients were predominately elderly men who presented with jaundice or nonspecific gastrointestinal symptoms. In most of the patients, serum pancreatic enzymes were normal or mildly elevated with an accompanying cholestatic biochemical profile. Elevated IgG levels and detection of autoantibodies were observed in 47% (8/17) and 35% (6/17), respectively. Thirteen patients showed histologic findings of lymphoplasmacytic infiltration and fibrosis, and one patient showed predominant infiltration of eosinophils. Fifteen patients revealed radiologic images of diffuse swelling of pancreas and the sclerosing pattern on direct pancreatogram. All of the features improved in response to oral steroid therapy. Two cases showed focal narrowing with upstream duct dilatation and thus, they were diagnosed as focal type. Diabetes mellitus concurred in 13 cases and primary sclerosing cholangitis and Sjogren's syndrome were present in 1 case, respectively. CONCLUSIONS: The recognition of autoimmune pancreatitis allows patients to avoid unnecessary surgery and recover with the administration of oral steroid.

A duodenal duplication cyst is an uncommon congenital anomaly that is usually encountered during infancy or in early childhood. Duodenal duplication cysts generally appear on the first or second portion of the duodenum and may cause duodenal obstruction, hemorrhage or pancreatitis. Here, we report a case of a duodenal duplication cyst on the second and third portion of the duodenum in an old aged man with obstructive jaundice and acute pancreatitis, which was treated successfully by a surgical excision.

BACKGROUND/AIMS: Diffuse or segmental irregular narrowing of the main pancreatic duct (MPD), as observed by endoscopic retrograde cholangiopancreatography (ERCP), is a characteristic feature of autoimmune pancreatitis (AIP). METHODS: ERCP findings were retrospectively examined in 40 patients with AIP in whom irregular narrowing of the MPD was detected near the orifice. The MPD opening sign was defined as the MPD within 1.5 cm from the orifice being maintained. The distal common bile duct (CBD) sign was defined as the distal CBD within 1.5 cm from the orifice being maintained. Endoscopic findings of a swollen major papilla and histological findings of specimens obtained from the major papilla were examined in 26 and 21 patients, respectively. RESULTS: The MPD opening sign was detected in 26 of the 40 patients (65%). The distal CBD sign was detected in 25 of the 32 patients (78%), which showed stenosis of the lower bile duct. The patients who showed the MPD opening sign frequently showed the distal CBD sign (p=0.018). Lymphoplasmacytic infiltration, but not dense fibrosis, was histologically detected in biopsy specimens obtained from the major papilla. CONCLUSIONS: On ERCP, the MPD and CBD adjacent to the major papilla are frequently maintained in patients with AIP involving the pancreatic head. These signs are useful for diagnosing AIP on ERCP.
