Which of the following dilators are used in the common duct?

Pratt
Van Buren
Bakes
Hegar

The correct answer is: Pratt

The appropriate choice for dilators used in the common duct is Bakes dilators. These are specifically designed for use in the biliary tree, including the common bile duct. They are utilized to gently dilate and facilitate access to the duct, which is crucial during certain surgical procedures. Pratt dilators, while also a type of urethral dilator, are primarily used for dilating the urethra, and therefore, are not the correct choice in the context of the common duct. Similarly, Van Buren dilators are used for urethral dilation, specifically in male patients, and Hegar dilators are meant for the dilation of the cervix during gynecological procedures. Each of these dilator types has a specific intended use throughout various surgical disciplines, but when it comes to dilation in the context of the common duct, Bakes dilators are the standard choice.
