Warm water infusion during sedated colonoscopy does not decrease amount of sedation medication used.

Background: Water infusion versus air insufflation during colonoscope insertion has been suggested to reduce patient discomfort and decrease sedation medication requirements. Warm water is thought to further facilitate colonoscopy perhaps by decreasing colon spasm.

Objective: To compare the utility of warm (35°-38°C) versus cool (20°-23°C) water infused during colonoscopic insertion by measuring patient sedation medication use and discomfort scores between the warm and cool water groups.

Use of a variable-stiffness colonoscope allows completion of colonoscopy after failure with the standard adult colonoscope.

Background And Study Aims: Experts fail to reach the cecum in 2 - 10% of colonoscopies. The purpose of this case series was to evaluate the efficacy of a small-caliber, variable-stiffness colonoscope in patients with incomplete colonoscopy.

Patients And Methods: The variable-stiffness colonoscope (Olympus America XPCF-140AL) was used by the same examiner to reattempt colonoscopy immediately in all patients in whom colonoscopy to the cecum with the standard colonoscope was incomplete.
