Summary
Endoscopic manometry of the sphincter of Oddi is a safe procedure with a low risk of pancreatitis. Risk increases in patients with abnormal sphincter manometry, especially those with idiopathic recurrent pancreatitis.
Area of Science:
- Gastroenterology
- Endoscopic procedures
- Sphincter of Oddi manometry
Background:
- Sphincter of Oddi manometry is used to evaluate patients with unexplained abdominal pain or idiopathic recurrent pancreatitis.
- Assessing the safety of this diagnostic procedure is crucial for patient care.
Purpose of the Study:
- To evaluate the safety of endoscopic manometry of the sphincter of Oddi.
- To identify risk factors for complications, specifically pancreatitis.
Main Methods:
- Prospective survey of 158 consecutive endoscopic manometry procedures in 126 patients.
- Patients had either unexplained pain post-cholecystectomy or idiopathic recurrent pancreatitis.
- Complications, defined as pancreatitis, were recorded and analyzed.
Main Results:
- Overall complication rate of pancreatitis was 8% (13/158 patients).
- Pancreatitis risk was significantly higher in idiopathic recurrent pancreatitis (29%) vs. unexplained pain (6%).
- Abnormal manometry (14%) and sphincter stenosis (50%) increased pancreatitis risk, particularly in idiopathic recurrent pancreatitis cases.
Conclusions:
- Endoscopic manometry of the sphincter of Oddi is relatively safe with a low incidence of mild pancreatitis.
- Patients with abnormal sphincter manometry, especially those with idiopathic recurrent pancreatitis and sphincter stenosis, face a higher risk.
- Risk stratification is important for patient selection and management.

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

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.
