The pancreaticoduodenectomy procedure includes the Whipple procedure and the Child method. In the Whipple procedure, the head of the pancreas and the pancreatic hook are removed, as well as the distal stomach, gallbladder, common bile duct and lymph nodes, and the upper end of the duodenum and jejunum, followed by the reconstruction of the stomach-jejunum, pancreatic duct-jejunum, and bile duct-jejunum. Another surgical procedure is pylorus-preserving pancreatic head duodenectomy. In this procedure, the right gastric artery is preserved, the duodenal artery and the right gastroretinal artery are cut off, and the duodenum is cut off 2 cm below the pylorus. Patients recover more quickly after surgery. The most classic is still pancreaticoduodenectomy, and there is also pancreaticoduodenectomy with preservation of the pylorus, which is applicable to some diseases. However, cancer of the head of the pancreas is less suitable for this type of surgery, especially if it is more extensive and infiltrates into the duodenum.
