What is the primary purpose of a cholangiogram during gallbladder surgery?

The primary purpose of a cholangiogram during gallbladder surgery is to visualize bile ducts. This imaging technique allows surgeons to check for any abnormalities, such as obstructions, stones, or strictures in the bile ducts, which are crucial for understanding the anatomy and pathology regarding gallbladder disease and its associated structures. By obtaining a clear view of the bile ducts, surgeons can make informed decisions about the surgical approach, ensuring that they do not miss any issues that may complicate the surgery or cause postoperative complications.

Using cholangiography aids in confirming whether the bile ducts are patent and functioning properly, which is vital for the patient's recovery and overall outcome of the surgery. This procedure directly addresses problems related to the biliary system, distinguishing it from the other options that focus on entirely different organs or systems.
