Academy of Medicine, Singapore clinical guideline on the use of sedation by non-anaesthesiologists during gastrointestinal endoscopy in the hospital setting.

Introduction: In Singapore, non-anaesthesiologists generally administer sedation during gastrointestinal endoscopy. The drugs used for sedation in hospital endoscopy centres now include propofol in addition to benzodiazepines and opiates. The requirements for peri-procedural monitoring and discharge protocols have also evolved.

A prospective, randomized study of the patency period of the plastic antireflux biliary stent: an interim analysis.

Background: There is as yet no ideal design of a plastic biliary stent with the longest patency period.

Objective: To study the safety and effective patency period of a new plastic antireflux biliary stent in the clinical setting.

Design: We conducted a prospective, randomized trial to compare the patency of 2 similar plastic biliary stents, one of which has an antiduodenobiliary reflux property.

Guidewire versus conventional contrast cannulation of the common bile duct for the prevention of post-ERCP pancreatitis: a systematic review and meta-analysis.

Background: The use of a guidewire (GW) for cannulation of the bile duct during ERCP may prevent post-ERCP pancreatitis (PEP).

Objectives: A systematic review and meta-analysis of GW-guided versus conventional contrast (CC)-guided bile duct cannulation for the prevention PEP.

Design: A November 2008 search of gray literature, databases, reference lists, and meeting abstracts was conducted for randomized, controlled trials comparing GW and CC.
