胰腺假性囊肿的病因分析

目的 分析胰腺假性囊肿(pancreatic pseudocyst,PPC)的病因特征,提高对PPC的病因认识.方法 收集2000年4月至2009年12月间长海医院收治的PPC患者的临床资料.采用统一的软件记录患者的人口学资料、假性囊肿的病因及原发病.结果 共收集PPC 366例.PPC的病因为:胆源性158例(43.2%),特发性79例(21.6%),酒精性50例(13.7%),外伤17例(4.6%),胰腺肿瘤9例(2.5%),高脂血症8例(2.2%),胰腺术后7例(1.9%),其他38例(10.3%).按亚特兰大分类标准,共有318例PPC可纳入该分类,其中急性PPC 204例(64.2%),慢性PPC 98例(30.8%),胰腺脓肿16例(5.0%).急性PPC中前4位病因分别为胆源性、特发性、酒精性及外伤;慢性PPC中前3位病因分别为胆源性、特发性、酒精性.结论 与欧美等西方国家明显不同,我国PPC的病因以胆源性为主,其次为特发性、酒精性.

Etiology of pancreatic pseudocyst

Objective To analyze the etiology in pancreatic pseudocyst (PPC). Methods Medical records were reviewed and analyzed for 366 PPC patients who were admitted in Changhai hospitals from April 2000 to December 2009 in terms. Demographic data, etiology and primary disorders of PPC patients were recorded. Results The causes of 366 patients varied as follow: gallstones in 158 patients (43.2%);idiopathic in 79 (21.6%); alcohol in 50 (13.7%); trauma in 17 (4.6%); pancreatic tumor in 9 (2.5%);hyperlipidemia in 8 (2.2%); post-operative in 7 (1.9%), other in 38 (10.3%). Depending on Atlantes classification systerm the PPCs were classified into acute PPC in 204 patients (64.2%), chronic PPC in 98 patients (30.8%) and abscess in 16 patients (5.0%). The 4 most common causes of acute PPC were gallstones, idiopathic, alcohol and trauma; the 3 most common causes of chronic PPC were gallstones,idiopathic, alcohol. Conclusions Gallstones is the main etiologic cause of the PPCs in China, followed by idiopathic and alcohol, which is significantly different with that in Western countries.
