A low-residue diet improved patient satisfaction with split-dose oral sulfate solution without impairing colonic preparation.

Background: Preprocedural dietary restrictions have been identified as a common reason potential candidates for colorectal cancer screening do not undergo colonoscopy as recommended.

Objective: To study whether a low-residue diet impacts bowel preparation with oral sulfate solution.

Design: Endoscopist blinded, prospective, randomized controlled trial.

A prospective safety study of a low-dose propofol sedation protocol for colonoscopy.

Background & Aims: Propofol has been shown to be an effective method for endoscopic sedation but there are few studies of low-dose propofol protocols for gastrointestinal endoscopy.

Methods: One hundred patients (American Society of Anesthesiology classes I-III) undergoing outpatient colonoscopy were enrolled prospectively in a multidrug propofol regimen that consisted of propofol, midazolam, and meperidine. Study outcome measures evaluated the level of sedation, length of procedure, sedation/recovery time, patient satisfaction, and adverse events.
