OBJECTIVES The removal of large bile duct stones (>12 mm) after endoscopic sphincterotomy (EST) remains a challenging issue in therapeutic endoscopy. The aim of this prospective, randomized, controlled trial was to compare the effectiveness and complications of EST followed by large balloon dilation (LBD) with that of EST followed by mechanical lithotripsy(More)
BACKGROUND Covered self-expandable metallic stents (SEMSs) are designed to prevent tumor ingrowth and can be removed if necessary. Only limited comparative data are available on the performance of covered SEMSs after primary placement versus reintervention. OBJECTIVE To assess the effectiveness and safety of covered SEMS placement either as primary(More)
BACKGROUND Octreotide is a potent inhibitor of pancreatic secretion, and corticosteroids suppress humoral and cellular activity. Both agents may reduce the frequency of post-ERCP pancreatitis. The aim of this study was to determine the effectiveness of octreotide and hydrocortisone in preventing post-ERCP pancreatitis. METHODS Three hundred fifty-four(More)
AIM During endoscopic retrograde cholangiopanc-reatography (ERCP), selective cannulation of the common bile duct (CBD) is required in most of the cases. METHODS From June 2001 till December 2002, all patients referred to our unit for ERCP were considered for entry into the study. Selective CBD cannulation was first attempted with a standard catheter with(More)
When confronting a biliary stricture, both benign and malignant etiologies must be carefully considered as a variety of benign biliary strictures can masquerade as hilar cholangiocarcinoma (CCA). Therefore, patients could undergo a major surgery despite the possibility of a benign biliary disease. Approximately 15% to 24% of patients undergoing surgical(More)
OBJECTIVE Achalasia is a well-defined esophageal motor disorder for which pneumatic dilation is an established therapeutic method. Even though it has been used for several years, there are limited data on the long-term outcomes of patients treated with this procedure. Hence, we aimed to evaluate the long-term efficacy of pneumatic dilation to control the(More)
Since therapeutic endoscopic retrograde cholangiopancreatography replaced surgery as the first approach in cases of choledocolithiasis, a plethora of endoscopic techniques and devices appeared in order to facilitate rapid, safe and effective bile duct stones extraction. Nowadays, endoscopic sphincterotomy combined with balloon catheters and/or baskets is(More)
During variceal bleeding, several factors may increase portal pressure, which in turn may precipitate further bleeding. This study investigates the early effects of endoscopic injection sclerotherapy (EIS) and endoscopic band ligation (EBL) on hepatic venous pressure gradient (HVPG) during acute bleeding and the possible influence in outcome. In 50(More)
OBJECTIVES Distal esophageal (Schatzki's) rings are a frequent cause of dysphagia. Bougienage is generally effective, but relapses are common. The aim of this study was to evaluate the effect of long-term antisecretory therapy on the relapse rate of lower esophageal rings after successful bougienage with Savary dilators. PATIENTS AND METHODS The study was(More)
BACKGROUND AND AIMS Conservative therapy for patients with acute colonic pseudo obstruction (Ogilvie's syndrome) may be successful initially but relapses are common. The aim of the present study was to evaluate the effect of polyethylene glycol (PEG) electrolyte balanced solution on the relapse rate of the syndrome after initial resolution with neostigmine(More)
