胰头癌是现代胰腺外科的重点和难点。说重点 ,是因为胰头癌在胰腺肿瘤病例中占 70 %以上 ,且发病率呈上升趋势 ;说难点 ,是因为胰头癌早期诊断困难 ,进展迅速 ,手术切除率和 5年生存率均低 ,疗效远不能尽如人意。从解剖学角度看 ,胰腺属于腹膜后器官 ,位置隐蔽 ,胰周临近许多重 Pancreatic cancer is the focus and difficulty of modern pancreatic surgery. The key point is that pancreatic cancer accounts for more than 70% of cases of pancreatic cancer, and the incidence rate is on the rise. The difficulty is that early diagnosis of pancreatic cancer is difficult and progresses rapidly. The surgical resection rate and 5-year survival rate are low. The efficacy is far from satisfactory. From an anatomical point of view, the pancreas belongs to the retroperitoneal organ and is concealed.
