Randomized Controlled TrialUse of a variable-stiffness colonoscope decreases the dose of patient-controlled sedation during colonoscopy: a randomized comparison of 3 colonoscopes.
The variable-stiffness colonoscope incorporates different degrees of stiffness of the insertion tube, which can be adjusted during the examination. Whether its use can lead to reduced procedure-related pain and sedative use is unknown. ⋯ The use of the new variable-stiffness adult-size colonoscope significantly reduced procedure-related pain and doses of sedative medications during colonoscopy.

Safety of intravenous midazolam and fentanyl for pediatric GI endoscopy: prospective study of 1578 endoscopies.
Data on safety of intravenous sedation in pediatric GI endoscopy are sparse. ⋯ Intravenous sedation with midazolam and fentanyl is safe for pediatric GI endoscopy. Serious adverse events are rare and no patient required hospitalization.

Suprapapillary puncture of the common bile duct for selective biliary access: a novel technique (with videos).
Selective cannulation of the bile duct while avoiding the potential mechanisms that initiate the cascade of pancreatic injury may prevent or minimize post-ERCP pancreatitis. This could be accomplished by suprapapillary needle puncture of the bile duct with a specially designed needle. ⋯ Suprapapillary puncture for biliary cannulation is a useful technique for selective cannulation of the bile duct and avoids injury to the pancreas but with higher complication rates. Further studies will be needed to define its safety and its relative benefits compared with conventional access methods.
