BACKGROUND AND STUDY AIMS Inadvertent injection of contrast agent into the pancreatic duct is believed to be an important contributor to pancreatitis occurring after endoscopic retrograde cholangiopancreatography (post-ERCP pancreatitis, PEP). Our aim was to examine whether primary deep biliary cannulation with a guide wire is associated with a lower rate(More)
OBJECTIVES Patients with Barrett's high-grade dysplasia (HGD) or early esophageal adenocarcinoma (EAC) that is shown on biopsy alone continue to undergo esophagectomy without more definitive histological staging. Endoscopic resection (ER) may provide more accurate histological grading and local tumor (T) staging, definitive therapy, and complete Barrett's(More)
BACKGROUND The cornerstone of management for acute cholecystitis is cholecystectomy. However, surgical intervention is contraindicated in the occasional patient. EUS-guided transduodenal gallbladder drainage may represent an effective minimally invasive alternative. OBJECTIVES To describe a new technique, EUS-guided cholecystenterostomy. DESIGN AND(More)
BACKGROUND Despite the recent improvement in techniques and patient selection, post-ERCP pancreatitis remains the most frequent and dreaded complication of ERCP. Recent studies suggest that pretreatment with glyceryl trinitrate (GTN) may prevent post-ERCP pancreatitis and improve cannulation success. OBJECTIVE To evaluate the effect of transdermal GTN on(More)
BACKGROUND AND AIM Recurrent stent obstruction necessitating reintervention is problematic and incompletely understood. The aim of the present study was to identify factor(s) predisposing to reintervention. METHODS Retrospective review of patients (n = 117) referred to a single major endoscopic referral centre for palliative enteral stenting from 1999 to(More)
BACKGROUND Recent medical literature on novel lumen-apposing stents for the treatment of pancreatic fluid collections (PFCs) is limited by small numbers, solo operators, and single-center experience. OBJECTIVE To evaluate a recently developed lumen-apposing, fully covered self-expandable metal stent (FCSEMS) in the management of PFCs. DESIGN(More)
BACKGROUND Succinylated gelatin (SG) is an inexpensive colloid that may combine ease of use with the advantages of a colloid to potentially increase EMR specimen size, leading to a higher rate of en bloc resection. OBJECTIVE To evaluate the safety, efficacy, and impact on EMR specimen size of SG as a submucosal (s.m.) injectant in comparison with normal(More)
BACKGROUND Duodenal duplication cysts are rare congenital anomalies. Symptomatic cases have classically been treated by surgical resection, which can be complex because of the close proximity of the cysts to the papilla. OBJECTIVE To describe a series of 8 patients with symptomatic duodenal duplication cysts who were treated endoscopically, with a special(More)
BACKGROUND Pancreas divisum (PD) is the commonest congenital pancreatic abnormality and is implicated as a cause of acute recurrent pancreatitis (ARP). We report our experience in minor papilla sphincterotomy (MPS) for this condition. Studies published at present have not examined MPS as the primary treatment method in a homogenous (i.e. only those with(More)
BACKGROUND The long-term efficacy of argon plasma coagulation (APC) in the management of gastrointestinal vascular lesions has not been evaluated in a large and well-defined series. The impact of APC on transfusion requirements and hemoglobin, and technical parameters including complications and number of treatment sessions, is assessed in this series. (More)
