The authors prepared obstructive jaundice models by cannulation into the common bile duct, using Wistar-strain rats, and examined active amines in the gastric wall and the incidence of AGML before and after biliary drainage. 1) The incidence of AGML was comparatively high in the group of 1-3 weeks' obstruction, while the incidence was greatly reduced after biliary drainage in the groups of 1-2 ...

INTRODUCTION Biliary obstruction is usually caused by choledocholithiasis. However, in some circumstances, alternative or concurring unusual ethiologies such as portal hypertensive biliopathy (PHB) must be considered. CLINICAL CASE We present the case of a 36-year-old female complaining of jaundice and pruritus. Liver function tests were compatible with biliary obstruction and the ultrasound ...

Malignant obstructive jaundice caused by tumor obstruction at the head of pancreas, peri-ampullary area, bile duct or gall bladder, and hilar lymphadenopathy carries considerable morbidity and mortality (Fig. 2.1a, b ). Biliary obstruction can lead to severe itching, and prolonged obstruction leads to impaired immune (both humoral and cellular) defense mechanisms predisposing the patient to inc...

BACKGROUND To summarize the experiences with the technique of percutaneous biliary stent placement for treatment of malignant biliary obstruction in patients with different types of biliary obstruction. METHODS Percutaneous biliary stent placement was performed in 126 patients with malignant biliary obstruction. The etiology included 56 cases of cholangiocarcinoma, 28 cases of pancreatic canc...

A prospective study was undertaken to evaluate the changes in portal venous pressure in patients with benign biliary obstruction (BBO) but without overt clinical, endoscopic or radiological evidence of portal hypertension. Portal venous pressure was measured at laparotomy in 20 patients (10 each with either benign biliary stricture or choledocholithiasis) before and after biliary decompression....

The aim of this study was to evaluate 64-slice spiral CT image reconstruction of the portal vein in biliary obstruction. A total of 34 clinical patients with biliary obstruction were confirmed by 64-slice spiral CT scanning with portal venous phase multi-planar reconstruction (MPR) of the biliary tract, curved planar reconstruction (CPR), thin-slab minimum-intensity projection (TS-MinIP) and ma...

CONTEXT When ERCP fails in the setting of combined biliary and duodenal obstruction, EUS-guided biliary drainage has emerged as an alternate method of biliary decompression. CASE REPORT We present a case of a 40-year-old man with advanced pancreatic cancer and a pre-existing duodenal wall stent who subsequently develops jaundice due to biliary obstruction. An ERCP was technically unsuccessful...

Fascioliasis is a health problem in several countries including the Islamic Republic of Iran.  In a review of the medical publications during 1990-2002, only 22 cases of biliary tract obstruction by fasciola hepatica have been reported.  Herein, we are adding a new case of fasciola hepatica causing bile duct obstruction and presenting with intermittent colicky pain, eosinophilia and bile duct d...

BACKGROUND Preoperative biliary drainage (PBD) has been widely used to treat patients with malignant biliary obstruction. However, it is still unclear which method of PBD (endoscopic nasobiliary drainage or endoscopic biliary stenting) is more effective. Thus, we carried out a meta-analysis to compare the safety and efficacy of endoscopic nasobiliary drainage (ENBD) and endoscopic biliary stent...
