Randomized Controlled Trial
Sublingual glyceryl trinitrate during colonoscopy and terminal ileal intubation: a randomized controlled trial.
Background and aims Sublingual glyceryl trinitrate has been used as an aid to cannulate the Sphincter of Oddi during endoscopic retrograde cholangiopancreatography. Its role in terminal ileal intubation during colonoscopy is unknown. This study examines the role of sublingual glyceryl trinitrate in terminal ileal intubation during colonoscopy. ⋯ Conclusions Terminal ileal intubation rates and timing were very good in both groups. Routine sublingual glyceryl trinitrate was not proven to be beneficial in improving terminal ileal intubation or intubation success rates in the hands of experienced colonoscopists. However, trends in this small study might suggest that glyceryl trinitrate could be useful in the hands of less experienced colonoscopists or in difficult terminal ileal intubation cases.
