In cirrhotic patients under pharmacologic treatment for portal hypertension, a reduction in hepatic venous pressure gradient (HVPG) of >or=20% of baseline or to <or=12 mm Hg markedly reduces the risk of variceal rebleeding. This study was aimed at evaluating whether these hemodynamic targets also prevent other complications of portal hypertension and(More)
After liver transplantation, the most common biliary complication is the anastomotic stricture, which is followed by biliary leakage. Studies have focused on the endoscopic treatment of biliary complications in transplanted patients with duct-to-duct reconstruction, showing a success rate of 70% to 80% after orthotopic liver transplantation and of 60% after(More)
BACKGROUND Underwater EMR (UEMR) has been reported as a new technique for the removal of large sessile colorectal polyps without need for submucosal injection. OBJECTIVE To evaluate (1) outcomes of UEMR, (2) whether UEMR can be easily performed by an endoscopist skilled in traditional EMR without specific dedicated training in UEMR, and (3) whether EUS is(More)
BACKGROUND Emergency sclerotherapy is still widely used as a first line therapy for variceal bleeding in patients with cirrhosis, particularly when banding ligation is not available or feasible. However, pharmacological treatment may stop bleeding in the majority of these patients. OBJECTIVES To assess the benefits and harms of emergency sclerotherapy(More)
BACKGROUND AND STUDY AIMS Data from a preliminary study suggested that the placement of a fully covered metal stent may be a valid alternative to surgery in patients who do not respond to standard endoscopic treatment. The aims of the current study were to evaluate the clinical success of self-expandable metallic stents (SEMS) in a large cohort of patients(More)
BACKGROUND Fully covered self-expanding metal stents are now being used to treat benign biliary diseases. AIMS To assess the outcomes of these stents as first-step therapy in patients with biliary leaks secondary to hepato-biliary surgery. METHODS Thirty patients (56.7% males; mean age: 60.2 ± 13 years) were retrospectively evaluated. The data collected(More)
BACKGROUND & AIMS Emergency sclerotherapy is used as a first-line therapy for variceal bleeding in cirrhosis, although pharmacologic treatment stops bleeding in most patients. We performed a meta-analysis comparing emergency sclerotherapy with pharmacologic treatment. METHODS MEDLINE (1968-2002), EMBASE (1986-2002), and the Cochrane Library (2002;4) were(More)
AIM To evaluate the efficacy of endoscopic treatment in patients who undergo OLTx or LRLTx and develop biliary complications. METHODS This is a prospective, observational study of patients who developed biliary complications, after OLTx and LRLTx, with duct-to-duct anastomosis performed between June 2003 and June 2007. Endoscopic Retrograde(More)
Since its development in the 1980s, endoscopic ultrasonography (EUS) has undergone a great deal of technological modifications. EUS has become an important tool in the evaluation of patients with various clinical disorders and is increasingly being utilized in many centers. EUS has been evolving over the years; EUS-guided fine needle aspiration (FNA) for(More)
