Pancreatic cancer is known as the “king of cancers”, with a median survival of less than 6 months and a serious threat to public health care. Although surgical resection of the tumor is the most promising cure, only 20% of patients have the chance of surgical resection.1 Pancreaticoduodenectomy (PD) is the most widely performed operation, because the majority of ductal carcinomas arise in the head of the pancreas. At present, pancreaticoduodenectomy includes resection the distal 1/3–1/2 of the stomach, the head of the pancreas, the common bile duct, the gallbladder, the entire duodenum, and the proximal 15 cm jejunum, and then reconstruct the digestive tract Büroreinigung Heidelberg and dissection of lymph nodes.s a complex procedure involving extensive resection with high risk of postoperative complication such as pancreatic and biliary fistula, delayed gastric emptying and postpancreatectomy hemorrhage.The Heidelberg triangle is a triangle composed of the superior mesenteric artery, common hepatic artery, celiac trunk and portal vein. Studies have shown2 that intraoperative dissection of the Heidelberg triangle area can improve the surgical resection rate, reduce the recurrence rate of pancreatic cancer, and improve the patient's prognosis. Anatomical knowledge is extremely important for the operator, but various emergencies during the operation require the operator to make judgments in a very short time. Therefore, we use a simple hand and foot teaching method to express the basic anatomical structure of the Heidelberg triangle. Clinicians and medical students can provide a good help.
