Long term results of balloon-occluded retrograde transvenous obliteration for portosystemic shunt encephalopathy in patients with liver cirrhosis and portal hypertension.

This study examined 19 patients with portosystemic shunt encephalopathy caused by a splenorenal shunt (SRS), which was treated with balloon-occluded retrograde transvenous obliteration (B-RTO). Long-term treatment outcomes were evaluated based on hepatic functional reserve and vital prognosis. Encephalopathy improved in all patients after shunt embolization and closure.

Balloon-occluded retrograde transvenous obliteration versus endoscopic injection sclerotherapy for isolated gastric varices: a comparative study.

Isolated gastric varices (IGV) have a lower risk of bleeding than esophageal varices, however IGV bleeding is associated with a higher mortality than bleeding of esophageal varices. In recent years, two widely used treatments for IGV have been balloon-occluded retrograde transvenous obliteration (B-RTO) and endoscopic injection sclerotherapy (EIS) using cyanoacrylate or ethanolamine oleate (EO). This study compared these two treatment methods for IGV.

Contrast-enhanced ultrasonograpic studies on pancreatic carcinoma with special reference to staining and muscular arterial vessels.

Comparative study of contrast-enhanced ultrasonography (CE-US) and histopathology of surgically resected specimens in 13 patients with pancreatic carcinoma. A time intensity curve was used to determine the percentage brightness increase in cancerous and normal regions and the patients were divided into two groups, hyperperfusion, with a percentage brightness increase over 80% (n=6) and hypoperfusion, with an increase of less than 80% (n=7) on CE-US. The hyperperfusion group included well-differentiated tubular adenocarcinoma, adenosquamous cell carcinoma and acinar cell carcinoma, while all 7 patients in the hypoperfusion group had moderately differentiated tubular adenocarcinoma.

Effect of Helicobacter pylori infection on esophagogastric variceal bleeding in patients with liver cirrhosis and portal hypertension.

Background And Aims: Bleeding from esophageal and gastric varices is a fatal event in patients with liver cirrhosis and portal hypertension. However, the effects of Helicobacter pylori (H. pylori) infection on esophagogastric variceal bleeding are not known.

Endoscopic ultrasonographic study of autoimmune pancreatitis and the effect of steroid therapy.

Background: Recently, endoscopic ultrasonography (EUS) has been used for the diagnosis of chronic pancreatitis (CP); however, EUS diagnosis of autoimmune pancreatitis (AIP) varies among different researchers. We investigated EUS findings in AIP and retrospectively analyzed them before and after steroid therapy.

Patients And Methods: The subjects were 32 patients with AIP and the EUS images of the pancreatic parenchyma were evaluated with reference to the Sahai criteria.

Direct cholangioscopy using a double-balloon enteroscope: choledochojejunostomy with intraductal biliary carcinoma.

A 75-year-old man who underwent choledochojejunostomy for gallstones 30 years ago was hospitalized for general malaise. Abdominal computed tomography revealed marked dilation of the intrahepatic bile duct in the right lobe and an image of a hypervascular tumor. Endoscopic retrograde cholangiography using double-balloon enteroscopy (DBE) showed a filling defect that was localized to the right hepatic bile duct.

Current status of ectopic varices in Japan: Results of a survey by the Japan Society for Portal Hypertension.

Aim: The Clinical Research Committee of the Japan Society for Portal Hypertension has conducted a nationwide questionnaire survey to clarify the current status of ectopic varices in Japan.

Methods: A total of 173 cases of ectopic varices were collected.

Results: Duodenal varices were found in 57 cases, and most of them were located in the descending to transverse parts.

Long-term results of balloon-occluded retrograde transvenous obliteration for gastric fundal varices: hepatic deterioration links to portosystemic shunt syndrome.

Background And Aims: It is well known that a large portosystemic shunt develops during portal hypertension. In this study, we studied the long-term effects of a large splenorenal shunt (SRS) on liver function and survival.

Methods: The subjects were divided into three groups: an SRS (-) group consisting of cirrhotic patients without SRS; an SRS (+) group consisting of patients with gastric fundal varices and SRS; and a balloon-occluded retrograde transvenous obliteration (B-RTO) group with a completely obliterated SRS by B-RTO.

Endoscopic retrieval of migrated plastic stent into bile duct or pancreatic pseudocyst.

Proximally migrated biliary plastic stent and migrated stent in the pancreatic pseudocyst are relatively rare complications. A migrated stent causes poor drainage conditions, which leads to secondary complications such as infection, abscess, perforation and, moreover, becomes a foreign object in the body, and retrieval or re-stenting is therefore necessary. The retrieval of a migrated stent includes surgical, percutaneous and endoscopic approaches, and the most non-invasive method is endoscopic retrieval.

[A case of hepatic eosinophilic granuloma, which needs distinction with metastatic liver cancer].

A 68-year-old man was referred to our hospital because of eosinophilia in peripheral blood and pancreatic tumor on abdominal US. He was accustomed to eating the raw flesh of wild boar and keeping wild boar, and under medical treatment for Diabetes. Pancreatic tumor was diagnosed to the pancreatic ductal cancer by the imaging examination and endoscopic transpapillary brushing cytology for pancreatic duct.

Lamivudine treatment-related morphological changes of esophageal varices in patients with liver cirrhosis.

Aim: Many studies have reported the therapeutic effects of lamivudine on cirrhotic patients with hepatitis B; however, no study has investigated the morphological changes of esophageal varices after lamivudine treatment.

Method: The morphological changes of esophageal varices in patients with cirrhosis were retrospectively compared between 12 patients treated with lamivudine and six historical untreated patients.

Results: In the treated group, the HBV DNA and hyaluronic acid (HA) levels in the serum were significantly lower than those in the untreated group (P = 0.

Endoscopic ultrasonography-guided cystogastrostomy for large pancreatic pseudocyst with obstructive jaundice--a case report.

The patient was a 45-year-old man with a history of heavy drinking. A pseudocyst about 30 mm in diameter was found in the head of his pancreas. About four weeks later an upper abdominal mass, abdominal pain and obstructive jaundice were confirmed.

[Arterial infusion chemotherapy for patients with advanced pancreatic cancer].

Although various therapies have been tried to improve advanced nonresectable pancreatic cancer, a sufficient consensus has not yet been obtained about the treatment. We have performed arterial infusion chemotherapy for pancreatic cancer in order to maintain QOL. The response rate was 17.

A case of mediastinal pancreatic pseudocyst successfully treated with somatostatin analogue.

A 57-year-old man with a 3-year history of chronic pancreatitis was admitted to our hospital with upper abdominal pain. Based on examination findings, the patient was diagnosed as having pseudocysts in the pancreatic body and the mediastinum that were associated with acute aggravation of chronic pancreatitis. Because of the patient refused an operation, he was submitted to conservative management including intramuscular injection with somatostatin analogue of 100 microg/day.

Pro-inflammatory signaling by Jun-N-terminal kinase in inflammatory bowel disease.

Since Jun-N-terminal kinase participates in intracellular signaling cascades resulting in inflammatory responses, inhibiting this pathway may represent a new treatment for inflammatory bowel disease including ulcerative colitis and Crohn's disease. However, the functional significance of the activation of this kinase in inflammatory bowel disease remains unclear. We investigated whether Jun-N-terminal kinase activation is increased in inflammatory bowel disease and analyzed the effects of SP600125, which decreases inflammatory cytokine synthesis by inhibiting the phosphorylation of this kinase.

Increased circulating concentrations of growth-related oncogene (GRO)-alpha in patients with inflammatory bowel disease.

Inflammatory bowel disease (IBD) is a chronic inflammatory state associated with increased risk of intestinal cancers. The aim of this study is to examine serum concentrations of growth-related oncogene (GRO)-alpha, a cytokine with inflammatory and growth-regulatory properties, in patients with IBD. We measured serum concentrations of GRO-alpha in 60 patients with ulcerative colitis, 42 patients with Crohn's disease, 16 patients with other colitides, 12 patients with colorectal cancer, and 40 normal subjects using an enzyme-linked immunosorbent assay.

Bifidogenic growth stimulator for the treatment of active ulcerative colitis: a pilot study.

Objectives: Experimental studies have shown that luminal antigens are involved in chronic intestinal inflammatory disorders. Bifidogenic growth stimulator (BGS) is a prebiotic preparation produced by Propionibacterium freudenreichii isolated from Swiss cheese. Previously BGS was shown to act in the colon as a growth stimulator of Bifidobacteria.

Interleukin-5 participates in the pathogenesis of ileitis in SAMP1/Yit mice.

SAMP1/Yit mice spontaneously develop ileitis resembling Crohn's disease (CD) without chemical or genetic manipulations. Since the focus of studies were Th1 cytokines, only Th1-type T cells were thought to be responsible for intestinal inflammation in these mice. To further characterize the pathogenesis of this ileitis, we investigated the implication of Th2 cytokines in ileitis of SAMP1/Yit mice.

Extended indication criteria for endoscopic mucosal resection of early gastric cancer with special reference to lymph node metastasis--examination by multivariate analysis.

The purpose of this study was to clarify extended indication criteria of endoscopic mucosal resection (EMR) for early gastric cancer (EGC) by analyzing the independent risk factors involved in lymph node metastasis (LNM). Subjects were 422 patients who underwent gastrectomy with lymph node dissection for EGC at the Kurume University Hospital from 1994 to 2001. The EGCs were mucosal cancers (M) in 252 cases and submucosal cancers (SM) in 170 cases.

Germinated barley foodstuff prolongs remission in patients with ulcerative colitis.

Germinated barley foodstuff (GBF) is a prebiotic which increases luminal butyrate production by modulating the microfloral distribution. GBF has been shown to reduce both clinical activity and mucosal damage in active ulcerative colitis (UC) with mild to moderate activity. However, the efficacy of GBF in patients with UC during the remission stage is unknown.
