Abstract Background /Object: Some patients with type 1 autoimmune pancreatitis (AIP), the pancreatic manifestation of IgG4-related disease, have normal serum IgG4. The aim of this study is to investigate the diagnostic value of measuring serum free light chains (FLCs) in type 1 AIP. Materials and methods Thirty-seven patients with type 1 AIP, and 21 healthy, 17 alcoholic chronic pancreatitis (ACP), 21 idiopathic chronic pancreatitis (ICP) and 20 pancreatic cancer (PC) patients were enrolled. Ser...

OBJECTIVES In patients with severe acute pancreatitis (SAP), early enteral nutrition (EN) is recommended by major clinical practice guidelines, but the exact timing for the initiation of EN is unknown. METHODS We conducted a post hoc analysis of the database for a multicenter (44 institutions) retrospective study of patients with SAP in Japan. The patients were classified into 3 groups according to the timing of EN initiation after the diagnosis of SAP: within 24 hours, between 24 and 48 hours, ...

Introduction Type 1 autoimmune pancreatitis is a chronic fibro-inflammatory disorder. We previously reported the involvement of M2 macrophages and basophils in autoimmune pancreatitis. It is reported that Group 2 innate lymphoid cells (ILC2s) and basophils play an important role in asthma. Thus, this study investigated the roles of innate lymphoid cells in autoimmune pancreatitis. Subjects and methods We recruited 28 patients with autoimmune pancreatitis (25 men and 3 women; mean age, 68.4 years...

Self-expandable metallic stents (SEMSs) are widely used for malignant biliary stricture (MBS). Acute pancreatitis is an early complication following SEMS placement. In the present case, the patient developed severe acute pancreatitis after SEMS placement for MBS because of metastatic lymph nodes. Endoscopic retrograde cholangiopancreatography, endoscopic sphincterotomy and an endoscopic nasobiliary drainage tube placement were performed. After seven days, an uncovered SEMS was placed; however, s...

Although chemical-induced animal models of colorectal cancer (CRC) suggest a lot about the disease, more efforts are required to establish metastasis models. Azoxymethane (AOM) and dextran sodium sulfate (DSS)-treated (AOM/DSS) Crl:CD-1 mice were sacrificed after 10 or 20 weeks in our previous study, and most colon tumors exhibited intramucosal adenocarcinomas. Our observations were extended until 30 weeks to study a colitis-associated advanced CRC mouse model, and explore whether linker threoni...

The biopsy-based diagnosis of autoimmune pancreatitis (AIP) is difficult but is becoming imperative for pathologists due to the increased amount of endoscopic ultrasound-guided biopsy tissue. To cope with this challenge, we propose guidance for the biopsy diagnosis of type 1 AIP. This guidance is for pathologists and comprises three main parts. The first part includes basic issues on tissue acquisition, staining, and final diagnosis, and is intended for gastroenterologists as well. The second pa...

Endoscopic retrograde cholangiopancreatography (ERCP) is an endoscopic modality established for diagnosis and treatment of pancreaticobiliary diseases. However ERCP in patients with surgically altered anatomy (SAA) has been difficult, and more invasive therapies have been primarily selected. The development of balloon assisted endoscopes (BAEs) innovatively facilitated ERCP in such patients. Recent advances of BAEs and other devices greatly contributed to increasing success of ERCP using BAEs (B...

Background and Aim A self-expandable metallic stent (SEMS) is commonly used for biliary stricture caused by pancreatic cancer. Covered SEMS may obstruct the cystic duct, causing acute cholecystitis. This study aimed to determine the outcomes of using a half-covered SEMS with an offset covered portion for preventing cystic duct obstruction. Methods Among 80 patients with half-covered SEMS placement for the treatment of pancreatic cancer-induced distal biliary stricture, 74 were followed up. The h...
