Summary
Endoscopic retrograde cholangiopancreatography (ERCP) has an 8% complication rate, with acute pancreatitis being the most frequent. Identifying risk factors is crucial for patient selection and avoiding diagnostic ERCP when possible.
Area of Science:
- Gastroenterology
- Endoscopic Procedures
- Surgical Interventions
Background:
- Endoscopic retrograde cholangiopancreatography (ERCP) is a complex endoscopic procedure.
- ERCP has evolved from diagnostic to a primarily therapeutic intervention.
- Post-procedural complications, occurring in 5-10% of cases, necessitate risk factor analysis.
Purpose of the Study:
- To analyze complications following ERCP.
- To identify and highlight risk factors for post-ERCP acute pancreatitis (pERCP-AP).
- To assess the necessity of risk factor identification for complication avoidance.
Main Methods:
- Retrospective analysis of 900 ERCP cases over 17 years.
- Study of overall ERCP complications.
- Special focus on pERCP-AP and its associated risk factors.
Main Results:
- ERCP has an 8% complication rate with a 0.43% mortality rate.
- Acute pancreatitis is the most common complication (3.7%), followed by bleeding (1.04%), perforation (0.69%), and septic biliary issues (1.21%).
- Identified risk factors for pERCP-AP include difficult sphincterotomy, failed CBD desobstruction, pancreatic sphincterotomy, repeated contrast injections, sphincter of Oddi dysfunction, and absence of chronic pancreatitis changes.
Conclusions:
- ERCP is relatively safe but carries risks, notably acute pancreatitis.
- Strict patient selection and avoidance of diagnostic ERCP in favor of non-invasive methods (MRI-cholangiography, echo-endoscopy) are recommended when risk factors are present.
- Understanding and mitigating risk factors can improve ERCP safety and outcomes.

01:25Acute Pancreatitis I: Introduction
Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
01:27Acute Pancreatitis I: Introduction
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
01:24Chronic Pancreatitis I: Introduction
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.

01:21Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
01:21Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
