Performance of a fully disposable, digital, single-operator cholangiopancreatoscope.

 Our aim was to evaluate the first use in humans of a new, single-use, digital, single-operator intraductal cholangiopancreatoscopy system (IDCP).  Data were collected retrospectively from four US institutions between February 2015 and April 2015. The visual impression of neoplasia or benign findings with IDCP was determined by the performing endoscopist.

Overactive bladder drugs and constipation: a meta-analysis of randomized, placebo-controlled trials.

Background: Anticholinergic drugs are commonly prescribed for symptomatic treatment of overactive bladder (OAB). While recent meta-analyses have characterized the prevalence of dry mouth among patients utilizing OAB medications, prevalence of constipation has not been systematically reviewed.

Aims: To provide an effect measure for constipation associated with anticholinergic OAB drugs versus placebo.

Pancreatic pseudocystwith stent placement in the background of narcotic use: a case report.

A 49 year old gentleman presents with recurrent abdominal pain. The patient has a known history of chronic pancreatitis, alcoholism and narcotic addiction. Work-up, including computed tomography (CT) of the abdomen, demonstrated a 5.

A prospective, blinded study of diagnostic esophagoscopy with a superthin, stand-alone, battery-powered esophagoscope.

Objectives: A more widely available, well-tolerated, and cost-effective technique is needed to screen a broad population at risk for esophageal cancer. An ideal solution might be to perform unsedated esophagoscopy with an entirely self-contained, small-caliber endoscope. In a prospective, blinded study in three phases, we compared the feasibility, patient tolerance, and diagnostic accuracy of esophagoscopy performed with a prototype, superthin, battery-powered esophagoscope (BPE) with standard video esophagogastroduodenoscopy (SVE).

Helical CT versus EUS with fine needle aspiration for celiac nodal assessment in patients with esophageal cancer.

Background: Conventional CT is insensitive for detection of metastatic involvement of celiac lymph nodes in esophageal cancer. Helical CT has theoretical advantages over "slice" CT in this regard, but its performance has not yet been prospectively studied.

Methods: Consecutive patients with untreated esophageal cancer were recruited after obtaining informed consent.
