Objective:Endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy (EST) are well accepted as the procedure of choice for diagnostic and therapeutic purposes of pancreaticobiliary disease. The aim of this study is to investigate the curative effect and complication of pancreaticobiliary disease managed by therapeutic ERCP. Methods: A total of 59 patients with common bile duct stone,acute obstructive suppurative cholangitis,malignant bile duct obstruction, acute or chronic pancreatitis,and sphincter of Oddi dysfunction. Each case was confirmed by ultrasonographic examination, diagnostic ERCP and blood amylase test. All patients underwent therapeutic ERCP such as EST, stone extraction and drainage. Results :Of the 59 patients, 16 patients with acute obstructive suppurative cholangitis and severe acute pancreatitis underwent urgent management of endoscopic intervention, stone extraction and endoscopic nasobiliary drainage. The remaining 43 patients underwent diagnostic ERCP,followed by therapeutic ERCP in cases of documented bile duct stone,sphincter of Oddi dysfunciton,or chronic pancreatitis. The success rate of endoscopic procedure was 100% ,and the complication rate was 6. 8% ,without mortality. Conclusion : In patients with pancreaticobiliary disease , therapeutic ERCP provides adequate management and is associated with low complication rates.

Due to the high incidence and mortality of digestive system malignant tumor,so it is of great significance to make further research for digestive tract tumor.Platinum drugs,one of the traditional drugs which is used for the chemotherapy for digestive system tumor,which has been extensively applied to the chemotherapy for malignant tumor.However,the resistance to the drugs exerts a serious influence on its curative effect.At present,it is believed that the nucleotide excision repair(NER)constitutes one of the most important mechanisms which results in the resistance to platinum drugs,mainly because it causes the twisting of DNA helix by removing large numbers of platinum compounds.The nucleotide excision repair cross complementation group 1(ERCC1)plays an important role in the process of NER.The different expression of ERCC1 in peripheral blood and tumor tissue of patients with digestive sysem tumor has a close connection with therapeutic effect of the platinum-containing chemotherapy.This article aims to provide an overview of the relation between the ERCC1 research development and the curative effect of cisplatin chemotherapy for digestive system tumor.
