Brief Summary

Multiple risk factors have been linked with post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP); therefore, it is critical to follow strategies to reduce associated risk, morbidity, and mortality. However, there are also factors, such as pancreatic duct stenting, which have shown evidence of PEP prevention. The investigators pursue to compare plastic vs biodegradable pancreatic stents in the prevention of PEP.

Detailed Description

Endoscopic retrograde cholangiopancreatography (ERCP) is a high-skilled endoscopic procedure, which is currently mainly used as a therapeutic mean for various pancreaticobiliary disorders. Its most common serious adverse event is PEP. Multiple risk factors have been linked with PEP (patient/procedure/operator-related). Therefore, it is critical to follow strategies to reduce associated risk, morbidity, and mortality.

A recent metanalysis reported an overall incidence of PEP close to 10%, with an even higher incidence (14.7%) in high-risk patients. PEP's risk factors work synergically and have exhibited up to a 40% incidence rate in multifactorial patients. However, there are also factors, such as pancreatic duct stenting, which have shown evidence of PEP prevention.

The prophylactic use of pancreatic duct stents (especially 5 Fr stents) has exhibited a statistically significant PEP severity and incidence reduction; particularly for high-risk patients, for those who have undergone inadvertent repeated pancreatic duct cannulation or those in whom it is difficult to perform biliary cannulation. Controversially, failed pancreatic duct placement has shown a 34.7% PEP incidence rate and is considered an independent risk factor for PEP. In the case of stent migration, stent-induced perforation may arise regardless of the type of stent used (plastic or metallic), but if no signs of peritonitis are displayed, the endoscopic approach may suffice for stent removal and tracks closure. Rarely the surgical approach is guaranteed for migrated stents in the presence of peritonitis or retroperitoneal fluid collection.

The investigators pursue to compare plastic vs biodegradable pancreatic stents in the prevention of PEP.

Primary Outcome Measures

Name	Time	Method
PEP prevention at 72 hours	up to 72 hours after randomization	Determine if plastic or biodegradable pancreatic stent placement renders PEP prevention. PEP is defined as proposed by Cotton et al in 1991(new hospitalization admission or 2/3-day hospital stay extension due to an abdominal pain suggestive of pancreatitis, plus a threefold increase of serum amylase/lipase above the normal limits 24 hours post-procedure).

Secondary Outcome Measures

Name	Time	Method
PEP prevention at 4 weeks	up to 4 weeks after randomization	Determine if plastic or biodegradable pancreatic stent placement renders PEP prevention. PEP is defined as proposed by Cotton et al in 1991(new hospitalization admission or 2/3-day hospital stay extension due to an abdominal pain suggestive of pancreatitis, plus a threefold increase of serum amylase/lipase above the normal limits 24 hours post-procedure).
