BACKGROUND Benign biliary strictures (BBS) have been endoscopically managed with placement of multiple plastic stents. Uncovered metal stents have been associated with mucosal hyperplasia and partially covered self-expandable metal stents with migration. Recently, fully covered self-expandable metal stents (CSEMSs) with anchoring fins have become available.(More)
BACKGROUND In patients with surgically altered anatomy, ERCP is often unsuccessful. Single-balloon enteroscopy (SBE) enables deep intubation of the small bowel, permitting diagnostic and therapeutic ERCP in this subset of patients. OBJECTIVE To determine the effectiveness of SBE in performing endoscopic retrograde cholangiography (ERC) in patients with(More)
Backgrounds. Limited effective palliative treatments exist for pancreatic cancer which includes surgery or chemotherapy. Radiofrequency ablation (RFA) uses high frequency alternating current to ablate diseased tissue and has been used to treat various tumors. In this study, we evaluated a prototype probe adjusted to the EUS-needle to perform EUS-RFA to(More)
BACKGROUND Few studies have described the role of multimodality therapy and the complexity of endoscopic management of pancreatic duct disruption. Our study aim was to analyse and confirm factors associated with the resolution of pancreatic duct disruption. METHODS Over 6 years, retrospective data on patients with pancreatic duct disruption managed(More)
OBJECTIVE Endoscopic therapy with pancreatic duct (PD) stenting in painful chronic pancreatitis is effective at reducing pain. Few studies have compared response to different PD stent diameters. In this study, we retrospectively analyzed the effect of PD stent diameter on hospitalization for abdominal pain in chronic pancreatitis. METHODS An existing(More)
BACKGROUND & AIMS Photodynamic therapy (PDT) for unresectable cholangiocarcinoma is associated with improvement in cholestasis, quality of life, and potentially survival. We compared survival in patients with unresectable cholangiocarcinoma undergoing endoscopic retrograde cholangiopancreatography (ERCP) with PDT and stent placement with a group undergoing(More)
BACKGROUND Partially covered metal stents (PCMS) have been increasingly used for both malignant and benign biliary indications. This study reports their complications and subsequent management. METHODS Over 5 years, all patients receiving biliary PCMS were followed prospectively until stent-related dysfunction or death. Data were analyzed for the(More)
PURPOSE Covered self-expanding metal stents (CSEMS) have been used for palliation of malignant distal biliary strictures. Occlusion of the cystic duct by CSEMS may be complicated by cholecystitis. This potentially could be prevented by placement of a transpapillary gallbladder stent (GBS). PATIENTS AND METHODS Between 11/2006 and 10/2007, a total of 73(More)
BACKGROUND Pancreatic duct (PD) stenting is beneficial for the treatment of pain in patients with PD strictures associated with chronic pancreatitis. Placement of metal stents has been reported but failed secondary to hyperplasia or migration. OBJECTIVE To investigate the outcome of patients with symptomatic and refractory PD strictures who had temporary(More)
BACKGROUND Current management of malignant gastric outlet obstruction (GOO) includes surgical diversion or enteral stent placement for unresectable cancer. We analyzed the long-term results, predictive factors of outcomes, and complications associated with enteral stents with focus on their management. METHODS Between 1997 and 2007, 46 patients with(More)
