Management of biliary stricture in patients with IgG4-related sclerosing cholangitis.

Background: We aimed to determine the optimal approach with endoscopic biliary drainage (EBD) and corticosteroid (CS) for the treatment of IgG4-related sclerosing cholangitis (ISC).

Methods: To evaluate the safety of EBD for treatment of biliary stricture caused by ISC, we assessed the risk of stent dislodgement and sought to determine the most appropriate time for stent removal. We also assessed the safety of treatment with CS alone for patients with obstructive jaundice, and the rate of and risk factors for biliary tract complications.

Prognosis of type 1 autoimmune pancreatitis after corticosteroid therapy-induced remission in terms of relapse and diabetes mellitus.

Background And Aim: Relapse and diabetes mellitus (DM) are major problems for the prognosis of autoimmune pancreatitis (AIP). We examined the prognosis of type 1 AIP after corticosteroid therapy (CST)-induced remission in terms of relapse and DM.

Methods: The study enrolled 82 patients diagnosed with type 1 AIP who achieved remission with CST.

[A case of gastric follicular lymphoma resected and diagnosed with laparoscopy and endoscopy cooperative surgery].

A woman in her 70s was diagnosed with a protruding mucosa-associated lymphoid tissue (MALT) lymphoma during a secondary health examination. After eradication of Helicobacter pylori, a biopsy revealed gastric follicular lymphoma (FL) and the lesion was still protruding one year later. F-fluorodeoxyglucose positron emission tomography showed focal nodular hypermetabolic activity, suggesting that FL may have transformed into a diffuse large B-cell lymphoma.

Evaluation of an e-learning system for diagnosis of gastric lesions using magnifying narrow-band imaging: a multicenter randomized controlled study.

 Magnifying narrow-band imaging (M-NBI) is useful for the accurate diagnosis of early gastric cancer (EGC). However, acquiring skill at M-NBI diagnosis takes substantial effort. An Internet-based e-learning system to teach endoscopic diagnosis of EGC using M-NBI has been developed.

Interobserver agreement in detection of "white globe appearance" and the ability of educational lectures to improve the diagnosis of gastric lesions.

Background: White globe appearance (WGA) refers to a small white lesion of globular shape underneath cancerous gastric epithelium that can be clearly visualized by magnifying endoscopy with narrowband imaging (M-NBI). WGA has been reported to be a novel endoscopic marker that is highly specific in differentiating early gastric cancer (GC) from low-grade adenoma, and has a significantly higher prevalence in early GCs than in noncancerous lesions. However, interobserver agreement in detecting WGA and whether training intervention can improve diagnostic accuracy are unknown.

Imaging findings of gastric calcifying fibrous tumour.

Calcifying fibrous tumours (CFTs) are rare benign lesions that usually affect the soft tissues, the mesentery and the peritoneum. Gastric CFT is particularly rare. Here, we report a CFT found incidentally in a 31-year-old male.

Encephalopathy, disseminated intravascular coagulation, and hemolytic-uremic syndrome after infection with enterohemorrhagic Escherichia coli O111.

An outbreak of enterohemorrhagic Escherichia coli (EHEC) occurred in Toyama and other prefectures in Japan during 2011. Some patients, including adults, showed complications such as encephalopathy, disseminated intravascular coagulation, and hemolytic-uremic syndrome, and the disease course was extremely aggressive. This report describes the clinical features of four patients infected with Escherichia coli (E.

[Concurrent chemo-radiotherapy for localized refractory non-Hodgkin's lymphoma--report of two cases].

Localized refractory diffuse large B-cell lymphomas (DLBCL) were treated with concurrent chemo-radiotherapy. Case 1 had right cervical lymphadenopathy. Lymphoma enlarged even after the fourth courses of chemotherapy consisting of cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP).
