Pancreatic stents in ERCP. Where are we?

Area of Science:

• Gastroenterology
• Endoscopy
• Pancreatology

Background:

• Post-ERCP pancreatitis (PEP) is a significant clinical challenge.
• Incidence rates for PEP vary widely (2.1%–24.4%).
• Variability stems from patient factors, endoscopist skill, and methodology.

Purpose of the Study:

• To elucidate the complex pathophysiology of Post-ERCP pancreatitis.
• To identify key risk factors contributing to PEP development.

Main Methods:

• Review of existing literature on PEP.
• Analysis of multifactorial elements contributing to PEP.
• Consideration of genetic predispositions.

Main Results:

• Pathophysiology involves chemical, thermal, mechanical, hydrostatic, enzymatic, allergic, and microbiological factors.
• Papillary instrumentation and contrast administration are key triggers.
• Genetic factors, like alpha-1-antitrypsin deficiency, can increase hemorrhagic PEP risk.

Conclusions:

• PEP is a complex complication with diverse contributing factors.
• Understanding these factors is crucial for risk mitigation.
• Further research into genetic predispositions may offer new insights.
