The pancreas, duodenum, and stomach are intricately related at this location, which is why pancreoduodenectomy is considered the pinnacle of digestive tract surgery.
After clearing the periphery, especially around the liver, Yang Ping began to focus on the pancreas, duodenum, and stomach, where the blood vessels were in extreme disarray.
The main blood vessels of the duodenum include the superior duodenal artery of the first segment, the branches of the gastroduodenal artery, and the posterior superior pancreaticoduodenal artery branches; the gastroduodenal artery itself is a branch of the hepatic artery, and these vessels are intricately intertwined.
The blood supply for the remaining three segments of the duodenum comes from the anterior and posterior arterial arches, from which branches extend to the pancreas and duodenum. The branches supplying the duodenum are known as terminal arteries, sometimes embedded within the pancreatic tissue.
