The duodenal bulb refers to the proximal most portion of the duodenum closest to the stomach and includes most of the D1 segment of the duodenum. It usually has a length of about 5 cm. It commences at the gastric pylorus and ends at the neck of the gallbladder. It is located posterior to the liver and the gallbladder and superior to the pancreatic head.
