The term portal biliopathy (PB) is used to describe the biliary abnormalities associated with portal hypertension. Between 5% and 30% of patients with PB develop biliary obstruction. We report on a patient with extrahepatic biliary obstruction caused by PB that was successfully managed with an intrahepatic segment 3 bypass. The traditional surgical approach for a patient with extrahepatic bilia...
UNLABELLED Bile acids are considered as extremely toxic at the high concentrations reached during bile duct obstruction, but each acid displays variable cytotoxic properties. This study investigates how biliary obstruction and restoration of bile flow interferes with urinary and circulating levels of 17 common bile acids. Bile acids (conjugated and unconjugated) were quantified by liquid chroma...
INTRODUCTION Recurrent biliary obstruction necessitating premature repeat endoscopic retrograde pancreatography (ERCP) remains a costly and morbid problem in patients undergoing treatment of post-orthotopic liver transplantation (OLT) biliary strictures. We evaluated the relationship between prednisone or sirolimus use and early recurrence of biliary obstruction given their negative effects on ...
Ceftriaxone (CTRX) is known to cause reversible biliary stones/sludge, which is called biliary pseudolithiasis. We report two rare cases of biliary obstruction by pseudolithiasis shortly after completing CTRX treatment. Stones and sludge, which had not been detected before CTRX administration, appeared in the gallbladder and common bile duct and led to biliary obstruction and acute cholangitis....
Background/Aims In distal malignant biliary obstruction, an antireflux metal stent (ARMS) with a funnel-shaped valve is effective as a reintervention for metal stent occlusion caused by reflux. This study sought to evaluate the feasibility of this ARMS as a first-line metal stent. Methods Patients with nonresectable distal malignant biliary obstruction were identified between April and Decemb...
Biliary endoscopic drainage using metallic self-expanded stents has become a well-established method for palliative treatment of malignant biliary obstruction. However, its occlusion, mainly by tumor overgrowth, is still the main complication without a standard treatment. We here describe a new method of treatment for biliary metallic stent occlusion, through the echo guided biliary drainage. W...
BACKGROUND Self-expandable metal stents (SEMS) are widely used for the palliative treatment of malignant gastrointestinal obstruction. Our aim was to evaluate the evidence comparing covered and bare SEMS in the digestive tract using meta-analytical techniques. METHODS A literature search was performed using PubMed, Cochrane Library, and Embase databases for comparative studies assessing the t...
INTRODUCTION Recently, multidetector computed tomography (MDCT) has been introduced into clinical practice. MDCT has become the noninvasive diagnostic test of choice for detailed evaluation of biliary obstruction. AIM the main objective of the present study was to evaluate the diagnostic value of MDCT compared to invasive procedures for detecting biliary obstruction causes. MATERIAL AND MET...
