The Clinical Features of Late Postoperative Cholangitis After Hepaticojejunostomy Brought on by Conditions other than Cancer Recurrence.

Purpose: Postoperative cholangitis and anastomotic strictures (AS) are long-term complications of biliary-enteric anastomosis (BEA).

Methods: We retrospectively reviewed data of patients who underwent bile duct resection with or without hepatectomy and investigated the risk factors for postoperative cholangitis, benign AS, and incidence of Clavien-Dindo (C-D) Grade III complications.

Results: Overall, data of 189 patients (115 men and 74 women) were retrospectively analyzed.

Possibility of Neoadjuvant Treatment for Radiologically Judged Resectable Pancreatic Cancer.

Survival remains poor even after resection of pancreatic cancer and the postoperative recurrence rate is extremely high. Thus, neoadjuvant treatment may improve outcomes for resectable pancreatic cancer (RPC). This study evaluated the efficacy of neoadjuvant therapy for radiologically judged RPC.

Evaluation of postprandial hypoglycemia in patients with nonalcoholic fatty liver disease by oral glucose tolerance testing and continuous glucose monitoring.

Objective: Nonalcoholic fatty liver disease (NAFLD) is often associated with insulin resistance and glucose intolerance. Postprandial hypoglycemia frequently occurs in NAFLD patients; however, the details remain unclear.

Patients And Methods: The 75-g oral glucose tolerance test (75gOGTT) in 502 patients with biopsy-proven NAFLD and continuous glucose monitoring (CGM) in 20 patients were performed, and the characteristics and causes of postprandial hypoglycemia were investigated.

Patatin-like phospholipase domain-containing protein 3 is involved in hepatic fatty acid and triglyceride metabolism through X-box binding protein 1 and modulation of endoplasmic reticulum stress in mice.

Aim: Non-alcoholic steatohepatitis (NASH) is the major cause of chronic liver disease worldwide. Endoplasmic reticulum (ER) stress is considered to be an important pathological characteristic in NASH. A sequence variation (I148M) in the patatin-like phospholipase domain-containing protein 3/adiponutrin (PNPLA3) gene is known to be associated with the development of NASH.

Glycemic variability is an independent predictive factor for development of hepatic fibrosis in nonalcoholic fatty liver disease.

Unlabelled: Patients with nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) often have metabolic disorders including insulin resistance and type 2 diabetes mellitus (T2DM). We clarified the predictive factors in glucose metabolism for progression of hepatic fibrosis in patients with NAFLD by the 75-g oral glucose tolerance test (75gOGTT) and a continuous glucose monitoring system (CGMS). One hundred sixty-nine patients (68 female and 101 male patients) with biopsy-proven NAFLD with performance with 75gOGTT were enrolled and divided into four groups according to the stage of hepatic fibrosis (F0-3).

Bofutsushosan, a Japanese herbal (Kampo) medicine, attenuates progression of nonalcoholic steatohepatitis in mice.

Background: Obesity-induced liver disease (nonalcoholic fatty liver disease, NAFLD) is now the commonest cause of chronic liver disease in affluent nations. There are presently no proven treatments for NAFLD or its more severe stage, nonalcoholic steatohepatitis (NASH). Bofutsushosan (BTS), a Japanese herbal (Kampo) medicine, long used as an anti-obesity medicine in Japan and other Asian countries, has been shown to reduce body weight and improve insulin resistance (IR) and hepatic steatosis.

Usefulness of Technetium-99 m-2-methoxy-isobutyl-isonitrile liver scintigraphy for evaluating disease activity of non-alcoholic fatty liver disease.

Aim:   Non-alcoholic steatohepatitis (NASH) is a progressive form of non-alcoholic fatty liver disease (NAFLD). Therefore, it is important to evaluate disease activity and distinguish NASH from simple steatosis in NAFLD. Technetium-99 m-2-methoxy-isobutyl-isonitrile ((99m) Tc-MIBI) is a lipophilic cation designed for myocardial perfusion scintigraphy in the diagnosis of ischemic heart diseases, and its retention reflects mitochondrial function.

A novel and comprehensive mouse model of human non-alcoholic steatohepatitis with the full range of dysmetabolic and histological abnormalities induced by gold thioglucose and a high-fat diet.

Background: The search for effective treatments of non-alcoholic steatohepatitis (NASH), now the most common chronic liver disease in affluent countries, is hindered by a lack of animal models having the range of anthropometric and pathophysiological features as human NASH.

Aims: To examine if mice treated with gold thioglucose (GTG) - known to induce lesions in the ventromedial hypothalamus, leading to hyperphagia and obesity - and then fed a high-fat diet (HF) had a comprehensive histological and dysmetabolic phenotype resembling human NASH.

Methods: C57BL/6 mice were injected intraperitoneally with GTG and then fed HF for 12 weeks (GTG+HF).

The latest idea in NAFLD/NASH pathogenesis.

Nonalcoholic fatty liver disease (NAFLD) is a metabolic disorder characterized by fatty accumulation in the liver without alcohol consumption. NAFLD ranges from simple steatosis to nonalcoholic steatohepatitis (NASH), which may progress to end-stage liver disease. The prevalence of NAFLD is rising because of an increasing prevalence of obesity and metabolic syndrome.

Clinicopathological features and medical management of intraductal papillary mucinous neoplasms.

Background: Intraductal papillary mucinous neoplasms (IPMN) are a clinicopathological entity that is being diagnosed with increasing frequency. However, the best approach to medical management of IPMN needs to be clarified. The aim of the present study was to identify preoperative features that may be predictors of malignant IPMN, and to define the medical management of IPMN of the pancreas.

Overexpression of carbonic anhydrase-related protein XI promotes proliferation and invasion of gastrointestinal stromal tumors.

Three isoforms of carbonic anhydrase-related protein (CA-RP) are evolutionally well conserved among the CA gene family but lack classical CA activity. Although the biological function of CA-RPs is unknown, overexpression of CA-RP VIII has been reported in certain tumor types. Based on the finding that CA-RPs are commonly expressed in the neuronal cells, we investigated expression of all three CA-RPs in gastrointestinal stromal tumor (GIST).

Biliopancreatic fistula caused by an intraductal papillary-mucinous tumor of the pancreas confirmed by biochemical analysis of mucin.

Intraductal papillary-mucinous tumor of the pancreas is occasionally accompanied by biliopancreatic fistula. However, it is difficult to show the inflow of mucin produced by the tumor into the common bile duct. To confirm the biliopancreatic fistula, the mucin-rich fraction was purified from the bile and stained with antimucin antibodies.

Diminished cellular immune response to carbonic anhydrase II in patients with Sjögren's syndrome and idiopathic chronic pancreatitis.

Context: A serum antibody to carbonic anhydrase II has been reported in patients with Sjögren's syndrome and idiopathic chronic pancreatitis.

Objective: To evaluate cellular immune response to carbonic anhydrase II in patients with Sjögren's syndrome and idiopathic chronic pancreatitis.

Patients: Idiopathic chronic pancreatitis (n=23), Sjögren's syndrome (n=12), alcoholic chronic pancreatitis (n=3) and normal controls (n=13).

Expression of carbonic anhydrase-related protein CA-RP VIII in non-small cell lung cancer.

Carbonic anhydrase-related protein (CA-RP VIII) lacks a Zn-binding motif which is essential for carbonic anhydrase activity. Therefore, CA-RP VIII is believed to have a no catalytic activity and a new biological property. In the present study, CA-RP VIII expression in non-tumorous lung and non-small cell lung carcinomas was investigated.
