True or False: CBD obstruction can occur with lesions in the head of the pancreas.

Cannabinoid obstruction can indeed occur with lesions located in the head of the pancreas, making the statement true. The head of the pancreas is anatomically situated near the common bile duct (CBD). When a lesion, such as a tumor, develops in this area, it can compress or directly invade the surrounding structures, including the CBD. This obstruction can lead to a series of complications, such as jaundice, due to the accumulation of bile.

The anatomy of the pancreas and its relationship to the CBD is crucial to understanding this phenomenon. The CBD runs adjacent to the head of the pancreas, and any mass effect from a pancreatic lesion can disrupt the normal flow of bile from the liver to the duodenum. This blockage can result in obstructive jaundice and other clinical symptoms associated with biliary obstruction.

Other options focus on conditions that might influence obstruction rates, but the direct connection between pancreatic lesions in the head and CBD obstruction substantiates the correctness of the true statement in this context.
