Summary
Sphincter of Oddi manometry can cause mild pancreatitis, especially in patients with chronic pancreatitis. Avoid pancreatic duct cannulation to minimize risks during this diagnostic procedure.
Area of Science:
- Gastroenterology
- Endoscopic Procedures
Background:
- Sphincter of Oddi manometry is a diagnostic tool for biliary and pancreatic issues.
- Complications, particularly pancreatitis, can arise from this invasive procedure.
Purpose of the Study:
- To investigate the complications of sphincter of Oddi manometry.
- To determine the frequency, severity, and causes of post-procedure pancreatitis.
Main Methods:
- Retrospective analysis of 207 sphincter of Oddi manometry procedures in 146 patients.
- Categorization of complications, focusing on acute pancreatitis.
- Comparison of pancreatitis rates based on cannulation site and presence of chronic pancreatitis.
Main Results:
- Acute pancreatitis occurred in 6% of investigations and 8% of patients, all mild.
- Pancreatitis risk was significantly higher with pancreatic duct cannulation (11%) versus bile duct only (1%).
- Patients with pre-existing chronic pancreatitis had a 26% risk of pancreatitis post-manometry, compared to 3% in others.
Conclusions:
- Sphincter of Oddi manometry carries a risk of mild pancreatitis, elevated in patients with chronic pancreatitis.
- Avoiding pancreatic duct cannulation and screening for chronic pancreatitis are crucial for safety.
- The procedure can be safely performed as an outpatient, with careful consideration of patient selection and technique.

01:30Acute Pancreatitis II: Clinical Manifestations and Management
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
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.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:26Endoscopic Procedures V: ERCP
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

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...
01:21Acute 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...
