Endoscopic Ultrasound Assessment of Pancreatic Duct Diameter Predicts Neuroendocrine Tumors and Other Pancreas Masses.

Objectives: Distinguishing neuroendocrine tumors (NETs) and other pancreas lesions from adenocarcinomas via endoscopic ultrasound (EUS) requires additional tissue for special staining and processing. Our aim was to determine if main pancreatic duct (PD) diameter on EUS helps to differentiate NET and other unusual tumors from adenocarcinoma.

Methods: We evaluated 30 consecutive patients diagnosed with NET or other pancreas lesions by EUS with 90 matched patients who were found to have adenocarcinoma.

High-risk symptoms do not predict gastric cancer precursors.

Background & Study Aims: Gastric intestinal metaplasia (GIM) is the most common precursor of gastric cancer. Our aim is to determine if presenting symptoms predict gastric cancer precursor lesions in a high-risk population.

Patient And Methods: Consecutive unique patients evaluated by endoscopy for upper gastrointestinal symptoms at the Los Angeles County Hospital between 2010 and 2014 were evaluated.

Randomized trial of cholangioscopy-guided laser lithotripsy versus conventional therapy for large bile duct stones (with videos).

Background And Aims: Bile duct stones >1 cm have a decreased incidence of successful endoscopic extraction and often require lithotripsy. Although previous guidelines suggested mechanical lithotripsy for large common bile duct stones, current guidelines suggest cholangioscopy-guided lithotripsy as an adjunct with or without balloon dilation or mechanical lithotripsy. However, no randomized trials have assessed the usefulness of this practice.

Metallic coil and N-butyl-2-cyanoacrylate for closure of pancreatic duct leak (with video).

Background And Aims: Pancreatic fistula is a challenging yet common adverse event of partial pancreatectomy. Our objective is to determine the feasibility of endoscopic closure of a pancreatic fistula using a combination of a metallic coil and N-butyl-2-cyanoacrylate (NBCA) glue.

Methods: A patient with a postoperative pancreatic stump leak recalcitrant to conservative management and pancreatic duct stent placement underwent endoscopic/fluoroscopic placement of a metallic coil in the pancreatic duct followed by injection of .

Narrow-band imaging versus white light versus mapping biopsy for gastric intestinal metaplasia: a prospective blinded trial.

Background And Aims: Gastric intestinal metaplasia (GIM) is a gastric cancer precursor. Narrow-band imaging (NBI) may improve detection of GIM. We compared detection of GIM with high-definition white-light (HD-WL) endoscopy, NBI, and mapping biopsies in a population with increased gastric cancer risk.
