Introduction

ERCP is a procedure that combines endoscopy with fluoroscopy to diagnose and treat disorders of the biliary and pancreatic ducts. During ERCP, a specialized endoscope is inserted through the mouth and advanced into the duodenum to reach the ampulla of Vater, where the common bile duct and pancreatic duct meet. Contrast dye is then injected, which outlines the biliary and pancreatic ducts, allowing for visualization and assessment of any abnormalities Endoscopy of the biliary tract is a minimally invasive procedure that plays a crucial role in the diagnosis and treatment of various biliary pathologies. It involves the use of an endoscope, a flexible tube with a light and camera attached to it, which allows direct visualization of the biliary system. This technique provides valuable information for accurate diagnosis and enables therapeutic interventions. There are several endoscopic techniques used in the evaluation and management of biliary tract disorders. The two main procedures are Endoscopic Retrograde Cholangio Pancreatography (ERCP) and endoscopic ultrasound (EUS). Let's discuss each of these techniques and their applications [1, 2].

Endoscopic Retrograde Cholangiopancreatography (ERCP)

ERCP is a procedure that combines endoscopy with fluoroscopy to diagnose and treat disorders of the biliary and pancreatic ducts. During ERCP, a specialized endoscope is inserted through the mouth and advanced into the duodenum to reach the ampulla of Vater, where the common bile duct and pancreatic duct meet. Contrast dye is then injected, which outlines the biliary and pancreatic ducts, allowing for visualization and assessment of any abnormalities Diagnosis of Biliary Pathologies. ERCP is used to diagnose conditions such as choledocholithiasis (gallstones in the common bile duct), biliary strictures, bile duct tumors, and congenital abnormalities of the biliary system.

Therapeutic interventions: ERCP allows for various therapeutic interventions, including stone removal from the bile duct, placement of biliary stents to relieve obstructions, dilation of strictures, and drainage of pseudocysts or abscesses [3]. EUS combines endoscopy with high-frequency ultrasound to obtain detailed images of the biliary system and surrounding structures. The endoscope used in EUS has an ultrasound probe at its tip, which can produce high-resolution images of the bile ducts and adjacent organs.

Staging of biliary tumors: EUS can assess the extent of biliary tumors by visualizing their size, invasion into adjacent structures, and involvement of nearby lymph nodes. EUSguided FNA can obtain tissue samples from suspicious lesions or lymph nodes for cytological or histological analysis, aiding in the diagnosis of biliary malignancies. EUS can help characterize the nature of biliary strictures by visualizing their location, length, and depth, which assists in determining the appropriate treatment approach [4].

These endoscopic techniques provide valuable diagnostic and therapeutic options for biliary tract pathologies. They are typically performed by skilled gastroenterologists or interventional endoscopists who have received specialized training in these procedures. It is important to note that while these techniques are generally safe, they carry a small risk of complications such as bleeding, infection, or perforation, which are usually rare in experienced hands Endoscopy of the biliary tract is a minimally invasive diagnostic and therapeutic procedure that involves the use of an endoscope, a flexible tube with a camera and light source, to visualize and access the biliary tract. The biliary tract includes the liver, gallbladder, and bile ducts, which are responsible for the production, storage, and transportation of bile. There are two main techniques used in endoscopic examination of the biliary tract: Endoscopic Retrograde Cholangio Pancreatography (ERCP) and Percutaneous Transhepatic Cholangiography (PTC) [5].

Conclusion

ERCP is a procedure in which an endoscope is passed through the mouth, esophagus, and stomach, and then into the duodenum, where the opening of the bile ducts is located. The endoscope is used to inject a contrast dye into the bile ducts, which allows for visualization of the ducts on X-rays. ERCP can also be used to perform interventions such as removing stones, placing stents to relieve blockages, and taking tissue samples for biopsy. PTC involves the insertion of a needle through the skin and into the liver to access the bile ducts. A contrast dye is then injected into the bile ducts, and X-rays are taken to visualize the ducts. PTC is often used when ERCP cannot be performed or is unsuccessful.
