Question

Which of the following statements is (are) correct with respect to postoperative cholangiography ?

1. A T-tube is in place in the common bile duct

2. Water-soluble contrast material is injected

3. The patency of biliary ducts is evaluated

Answer 1

Postoperative cholangiography is a procedure used to assess the patency and check for obstructions within the biliary ducts after gallbladder surgery, often using a T-tube and water-soluble contrast material for clear imaging.

Step-by-step explanation:

Postoperative cholangiography is a diagnostic imaging technique used after gallbladder surgery. This procedure assesses the patency of biliary ducts and potential obstructions within the biliary tree. In this process, a T-tube may be placed in the common bile duct post-surgery to facilitate the injection of a water-soluble contrast material. This contrast material allows for clear imaging of the biliary tract, helping to evaluate the integrity and functionality of the bile ducts.

More specifically, postoperative cholangiography will:

1. Utilize a T-tube placed in the common bile duct to access the biliary system.
2. Inject water-soluble contrast material to enhance the visibility of the biliary ducts on imaging.
3. Allow healthcare professionals to evaluate the patency and ensure there is no obstruction in the biliary ducts, which could result in conditions like obstructive jaundice if present.

While similar in some aspects, an endoscopic retrograde cholangiopancreatography (ERCP) is a separate procedure where the contrast is injected through an endoscope and is often used to diagnose rather than postoperatively assess.
