老年慢性胰腺炎的发病率不详。在我国,胆系疾病为慢性胰腺炎的主要原因,老年人胆系疾病的发病率并无下降,故推测我国的老年慢性胰腺炎的发病率可能较高,准确统计数字尚待进一步调查。老年人胰腺的腺体萎缩、纤维化及胰管上皮细胞增生等生理性退行性变化,与慢性胰腺炎之病变相重叠,给此项研究带来一定困难。目前研究资料表明,老年慢性胰腺炎的临床特点有: The incidence of senile chronic pancreatitis is unknown. In our country, biliary diseases are the main cause of chronic pancreatitis, and the incidence of gallbladder disease in the elderly does not decline. Therefore, it is speculated that the incidence of elderly chronic pancreatitis in our country may be high, and accurate statistics are yet to be further investigated. The elderly patients with pancreatic gland atrophy, fibrosis and pancreatic ductal epithelial cell proliferation and other physiological degenerative changes, and the overlap of lesions of chronic pancreatitis, to bring some difficulties in this study. The current research shows that the clinical features of elderly chronic pancreatitis are:
