Unresolved issues about post-ERCP pancreatitis: an overview.

Area of Science:

• Gastroenterology and Hepatology
• Surgical Complications
• Clinical Risk Assessment

Background:

• Post-ERCP pancreatitis is a frequent and serious complication of endoscopic retrograde cholangio-pancreatography (ERCP).
• Despite extensive research, understanding of its mechanisms, risk factors, and prediction remains incomplete, with varied incidence rates due to differing diagnostic criteria.
• Significant advancements have been made in identifying predictive factors and defining the complication.

Purpose of the Study:

• To elucidate the mechanisms and identify risk factors associated with post-ERCP pancreatitis.
• To establish reliable criteria for predicting and defining post-ERCP pancreatitis.
• To explore potential methods for preventing this complication.

Main Methods:

• Analysis of data from four large prospective multicenter trials.
• Identification of patient-related and technique-related risk factors.
• Evaluation of clinical conditions, procedural factors, and laboratory tests for early prediction.

Main Results:

• Key patient and technique-related risk factors for post-ERCP pancreatitis have been identified.
• Clinical, procedural, and patient factors, along with laboratory tests, can predict early post-ERCP pancreatitis.
• Efforts have been made to standardize criteria for defining post-ERCP pancreatitis, though consensus is not universal.

Conclusions:

• Recent research has significantly advanced the understanding of post-ERCP pancreatitis.
• Identified risk factors and predictive markers improve the ability to manage patients undergoing ERCP.
• Further standardization of diagnostic criteria is needed to clarify the true incidence and guide clinical practice.
