目的 探讨胰性脑病的可能的发病机制、发病情况及防治措施.方法 计算机检索中文科技期刊全文数据库(1989～2004),收集有关胰性脑病的临床研究,并进行统计分析.结果 共纳入43篇文献,435例患者.胰性脑病在重症急性胰腺炎中的发病率远高于轻症急性胰腺炎;发病年龄趋向中、老年;病死率为43.67%;病因仍以胆系疾病为主;伴发低氧的几率不高于未并发胰性脑病患者.结论 胰性脑病的发生可能是多因素共同作用的结果,仍需进一步探讨其发病机制.血清髓鞘碱性蛋白有望成为有价值的诊断指标.防治以治疗原发病急性胰腺炎为主,重在预防.胰酶抑制剂和早期营养支持有一定预防作用.
Objective To discuss the pathogeny， treatment and prophylactic measures of postcholecystectomy syndrome (PCS). Methods The clinical data of 150 patients with laparoscopic PCS in our department from October 2000 to March 2009 were analyzed. Results Etiological factors were found in 131 patients: one hundred and twelve cases were due to the reasons of biliary system, including bile duct residual stones after cystic resection， the injury bile duct stenosis， a long residual cystic canal， nipple benign stricture, bile duct tumor etc; Nineteen examples were due to other reasons, including gallbladder stone merger reflux gastritis, gastroduodenal ulcer， diverticulum beside duodenal nipple, and so on, which resulted in the symptoms un-release after cystic resection. Nineteen cases were not found organic lesion. In ones whose etiological factors were definite, 117 cases were treated with different surgeries according to different etiological factors; another 33 cases were treated with conservative treatment. Total 145 cases were followed up, and 139 cases in them were cured or relieved at different degrees. Conclusion Careful preoperative examination, normalized operation avoiding damaging bile duct and leaving behind bile duct stones can effectively prevent laparoscopic PCS.
