The neck of the pancreas supports the pylorus of the stomach. It starts from the top right part of the front of the head of the pancreas. The neck is around 2.5 cm in length. In the beginning it moves up and forward and then to the left to join the body of the pancreas. It’s a bit flat on top. The stomach’s pylorus is supported by the antero-superior surface. The end of the portal vein is connected with the neck’s postero-inferior surface. The gastroduodenal artery indents it on the right.
