Early Pancreatic Duct Stent Removal in Preventing Post-endoscopic

Status Completed

Clinical Trial Summary

Temporary pancreatic duct stent placement during endoscopic retrograde cholangiopancreatography (ERCP) has been recommended for post-endoscopic pancreatitis (PEP) prophylaxis in high risk patients, including those in whom accidental pancreatic duct cannulation has occurred. However, the optimal duration of stent placement remains an open question. The investigators aim is to assess if immediate stent removal is effective in the prevention of PEP after accidental pancreatic duct cannulation.

Clinical Trial Description

Recent meta-analyses of randomized controlled trials confirmed that pancreatic stent placement after ERCP reduces the risk of PEP but the optimal duration of stent placement remains an open question. It has been suggested that in truly high-risk patients the pancreatic stent must be left in place for a minimum of 24 hours or more whereas in patients at lesser risk pancreatic duct drainage probably only needs to be maintained for a few hours or less. Leaving the stent in place at the end of the ERCP procedure carries the disadvantage of radiological follow-up until spontaneous dislodgment occurs or endoscopic removal is deemed timely; moreover, proximal migration has been reported, requiring endoscopic or even surgical removal. There is a paucity of data comparing immediate removal with spontaneous dislodgment in high-risk patients. In one study, significantly higher rates of PEP were detected in patients in whom a pancreatic stent was removed immediately at the end of the ERCP procedure than in those in whom the stent was left in place: unfortunately, only patients undergoing a precut sphincterotomy were evaluated in that study which was published only in abstract form. Therefore, it is still uncertain whether leaving a stent in place is more effective than immediate removal in preventing PEP in high-risk patients. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
