Improved oral intake after palliative duodenal stenting for malignant obstruction: a prospective multicenter clinical trial.

Objectives: We sought to test the hypothesis that placement of a new nitinol duodenal self-expandable metallic stent (SEMS) for palliation of malignant gastroduodenal obstruction is effective and safe in allowing patients to tolerate an oral diet.

Methods: In a prospective multicenter study, SEMSs (Duodenal WallFlex, Boston Scientific) were placed to alleviate gastroduodenal obstruction in inoperable patients without the ability to tolerate solid food. The primary study end point was improvement in oral intake monitored according to the 4-point Gastric Outlet Obstruction Scoring System (GOOSS) up to 24 weeks after stent placement.

Nocturnal reflux episodes following the administration of a standardized meal. Does timing matter?

Objectives: Prospective evidence supporting lifestyle modifications, including avoidance of late evening meals, for gastroesophageal reflux disease (GERD) sufferers is lacking. The aim of this study was to determine the difference of supine esophageal acid exposure in patients consuming an early or late standard meal relative to bedtime.

Methods: This is a prospective, randomized unblinded crossover trial.

Is routine ultrasound guidance for central line placement beneficial? A prospective analysis.

Objective: Portable ultrasound devices have become more readily available in the intensive care unit setting, but their utility outside of controlled trials remains unproven. We sought to determine how the availability of ultrasound guidance affected the types and number of complications during central line placement.

Design: Review of a prospectively maintained database in a 20-bed combined intensive care unit.
