近年来胰腺癌的发病率在世界范围内有增加的趋势,但治疗效果不能令人满意。这主要是因为胰腺癌的症状隐匿,早期诊断较为困难,另外胰腺周围解剖关系复杂,多在做出诊断时已丧失了根治性切除的可能。文献资料表明,目前约有85%～90%的病人确诊时就已无法根治切除,能行根治手术者只有10%～15%左右。然而随着肿瘤的生长,约70%的胰腺癌病人将出现梗阻性黄疸,而且约90%的胰头癌病人的主要症状也是梗阻性黄疸。长期的黄疸将对机体的各脏器和功能造成损害,主要表现为:①长时间的黄疸对肝脏功能造成损害,最终可导致肝脏功能衰竭;②梗阻性黄疸不
In recent years, the incidence of pancreatic cancer has increased worldwide, but the treatment effect is not satisfactory. This is mainly due to the hidden symptoms of pancreatic cancer, early diagnosis is more difficult, in addition to the complex relationship between pancreas around the anatomy, and more in the diagnosis has lost the possibility of radical resection. According to the literature, at present about 85% to 90% of patients have been unable to undergo radical resection when they are diagnosed, and only about 10% to 15% of those who can undergo radical surgery. However, with the growth of tumors, about 70% of pancreatic cancer patients will have obstructive jaundice, and about 90% of patients with pancreatic cancer are the main symptoms of obstructive jaundice. The long-term jaundice will cause damage to the organs and functions of the body, mainly as follows: 1 long-term jaundice causes damage to the liver function, and ultimately can lead to liver failure; 2 obstructive jaundice is not
