Ruptured pancreaticoduodenal pseudoaneurysm causing arterioportal fistula: combined transarterial and transportal embolization.

Background: Arterioportal fistulas are rare vascular disorders of the abdominal viscera. They are arteriovenous communications between the splanchnic arteries and the portal vein or its tributaries. We herein report a case of an extrahepatic arterioportal fistula that was caused by rupture of a pseudoaneurysm of the pancreaticoduodenal artery and successfully treated with embolization using a combination of the arterial and percutaneous transhepatic portal venous approaches.

[A case of liver abscess caused by hypermucoviscous Klebsiella pneumoniae with septic pulmonary embolism].

A 69-year-old man consulted a local doctor because of a chief complaint of fever and anorexia. CT showed a giant liver mass of the right hepatic lobe and multiple pulmonary nodules. The patient was admitted to our hospital.

[Jejunal varices after choledochojejunostomy treated with laparotomic transcatheter variceal embolization].

Portal hypertension induces collateral shunt formation between the portal and systemic circulation, decompressing the elevated portal pressure. Ectopic varices outside of the gastroesophageal region, such as jejunal varices, are rare conditions. This report describes the successful embolization of ruptured jejunal varices resulting from an extrahepatic portal obstruction.

Simultaneous combined balloon-occluded retrograde transvenous obliteration and partial splenic embolization for gastric fundal varices.

Background: We previously reported the techniques and usefulness of simultaneous combined balloon-occluded retrograde transvenous obliteration (B-RTO) and partial splenic embolization (PSE), based on the hypothesis that concomitant PSE can diminish the increase in portal venous pressure after B-RTO.

Objective: After experiencing more cases and performing longer-term follow-up, we re-evaluated the efficacy of simultaneous combined B-RTO and PSE for gastric fundal varices (GVs).

Methods: We performed B-RTO in 36 consecutive patients treated for GVs from 2005 to 2013.

Simultaneous combined balloon-occluded retrograde transvenous obliteration and partial splenic embolization for portosystemic shunts.

Purpose: To evaluate the efficacy and safety of simultaneous combined balloon-occluded retrograde transvenous obliteration (B-RTO) and partial splenic embolization (PSE) for gastric varices and/or hepatic encephalopathy.

Materials And Methods: B-RTO was performed in 19 consecutive patients with gastric varices and/or hepatic encephalopathy, of whom 10 received simultaneous combined B-RTO and PSE (group 1) and nine received B-RTO monotherapy (group 2). To evaluate the safety of these techniques, we analyzed 20 patients who received PSE monotherapy during the same period as a control group (group 3).

[A case of malignant peritoneal mesothelioma successfully treated with systemic chemothrapy].

A 64-year-old man with a 2-month history of abdominal distension was admitted for transient cerebral ischemic attack. A CT scan revealed massive ascites. Laparoscopy showed multiple whitish nodules on the visceral peritoneum and the omentum.

[Gemcitabine treatment in patients with stage IV pancreatic cancer and prognostic factors for survival of patients with stage IVb(a retrospective survey at 15 hospitals in Niigata Prefecture)].

We performed a retrospective survey at 15 hospitals in Niigata Prefecture to assess the effectiveness of gemcitabine in patients with stage IV pancreatic cancer and to analyze prognostic factors impacting survival in patients with stage IVb. The subjects were 244 unresectable or metastatic pancreatic cancer patients(IVa 68, IVb 176)who were treated with gemcitabine as first-line therapy. The overall response rate was 6.

Liver injury induced by a Japanese herbal medicine, sairei-to (TJ-114, Bupleurum and Hoelen Combination, Chai-Ling-Tang) R1.

The case is reported of a man who showed acute hepatitis with jaundice after he was given a Japanese herbal medicine, sairei-to (TJ-114, Bupleurum and Hoelen Combination, Chai-Ling-Tang). Unusually, the component thought to be responsible for the observed drug-induced liver injury was able to be identified. Lymphocyte migration inhibition testing indicated that the tuber of the perennial herbage Pinellia ternate was the causative agent.

[A case of gastric cancer with abdominal wall invasion treated by weekly low-dose paclitaxel therapy].

Here we report a case of gastric cancer with diffuse abdominal wall invasion treated with weekly low-dose paclitaxel therapy. A 62-year-old male visited our hospital because of abdominal distention, prepubic tumor,and testicular hydrocele. Computed tomography revealed diffuse swelling of the abdominal wall and hydronephrosis of the right kidney.

Blockade of CXCL10 protects mice from acute colitis and enhances crypt cell survival.

Crypt cell renewal is essential for normal intestinal homeostasis as well as mucosal regeneration following injury. However, the factors regulating crypt cell growth in pathological conditions are not fully understood. We report here that the endogenously produced chemokine CXCL10 regulates crypt cell proliferation.
