During an ERCP, what is the primary purpose of the procedure?

The primary purpose of an Endoscopic Retrograde Cholangiopancreatography (ERCP) is to visualize the bile and pancreatic ducts. This procedure combines the use of endoscopy and fluoroscopy to allow a healthcare provider to view these specific ducts and assess any issues that may be present, such as obstructions, gallstones, or strictures.

In doing so, ERCP serves not only as a diagnostic tool but also as a therapeutic one, enabling the treatment of certain conditions like removing bile duct stones or placing stents to alleviate blockages. By directly accessing these ducts through the duodenum, the images obtained during ERCP can help guide surgeons and gastroenterologists in making informed decisions about patient care.

The other options do not align with the primary purpose of ERCP. Measuring blood glucose levels pertains to diabetes management and is unrelated to the bile or pancreatic systems. Visualizing the intestines typically involves different imaging methods, such as colonoscopy or imaging studies like CT scans. Assessing liver function usually requires blood tests rather than a procedure like ERCP, which focuses specifically on the ducts. Thus, visualizing the bile and pancreatic ducts is the correct and main goal of ERCP.
