BACKGROUND The transjugular intrahepatic portosystemic stent shunt (TIPSS) is effective in the management of both oesophageal and gastric variceal bleeding. Although it has been reported that gastric varices can bleed at pressures of < or = 12 mm Hg, this phenomenon has been little studied in the clinical setting. AIMS To assess the efficacy of TIPSS on rebleeding and mortality following gast...

AIM To investigate the association between plasma concentrations of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and formation of esophageal varices. METHODS Thirty-five patients with alcoholic cirrhosis were divided into three groups according to the Child-Pugh classification: grade A (n=11, 32%), B (n=12, 34%), and C (n=12, 34%). System hemodynamic parameters were measured using sp...

BACKGROUND Prediction of esophageal varices in cirrhotic patients by noninvasive methods is still unsatisfactory. OBJECTIVES To evaluate the accuracy of an artificial neural network (ANN) in predicting varices in patients with HBV related cirrhosis. PATIENTS AND METHODS An ANN was constructed with data taken from 197 patients with HBV related cirrhosis. The candidates for input nodes of the...

Some patients with cirrhosis experience rupture of venous varices before operation, and liver transplantation is a therapy of last resort for these patients. However, we have experienced two cases of intraoperative rupture in whom no abnormalities of the venous varices were seen on endoscopy before operation. One patient with ruptured gastrointestinal varices was treated by direct surgical liga...

a 3 × 2 factorial experiment was conducted to investigate the effect of thymol + carvacrol (0, 100 and 200 mg/kg) on ileal microbial population and jejuna and ileal histomorphology of broilers fed carboxy methyl cellulose (cmc: 0 and 2%) containing diet. each of the 6 dietary treatments was replicated 5 times with 12 chicks each from 0 to 42 days of age. there was no interaction effect of cmc a...

presented to our department with recurrent lower gastrointestinal bleeding. Her past history was remarkable for a choledochal cyst excision with hepaticojejunostomy 2 years ago. Intermittent massive bleeding started 6 months after the surgery for which the patient received blood transfusions as the source of the bleeding was not identified. On examination the stools were maroon colored stool bu...

OBJECTIVE This study was deigned to evaluate the technique and clinical efficacy of the use of percutaneous transportal sclerotherapy with N-butyl-2-cyanoacrylate (NBCA) for patients with gastric varices. MATERIALS AND METHODS Seven patients were treated by transportal sclerotherapy with the use of NBCA. For transportal sclerotherapy, portal vein catheterization was performed with a 6-Fr shea...

Ectopic stomal varices are an unusual cause of gastrointestinal hemorrhage. The term "ectopic stomal varices" means abnormally dilated veins that have developed in the stomal mucosa. We describe the 2D reformatted and 3D volume rendered images by MDCT in a patient with an episode of acute bleeding from the colonic stoma. This case indicates that the 2D reformatted and 3D volume rendered images ...

Variceal bleeding is one of the most serious complications of portal hypertension. The driving force for the development of varices is an increase in portal pressure. As portal hypertension progresses, varices dilate until they finally rupture and bleed. This sequence of events might be prevented by achieving a sufficient decrease in portal pressure or by acting locally at the varices with endo...
