ARTICLE HIGHLIGHTS
Research background
Our previous study revealed that cholelithiasis patients who undergo endoscopic sphincterotomy/endoscopic papillary balloon dilatation (ES/EPBD) are at a greater risk for subsequent cholangiocarcinoma, while cholelithiasis patients who undergo cholecystectomy (CCY) have a much lower risk for subsequent cholangiocarcinoma.
Research motivation
Because of problems in prior study’s design, we could not identify whether different inflammation sites or CCY-reduced recurrent biliary events (RBEs) influenced the subsequent cholangiocarcinoma risk in cholelithiasis patients.
Research objectives
To evaluate the relationships of recurrent biliary events with subsequent cholangiocarcinoma risk.
Research methods
We selected symptomatic choledocholithiasis patients older than 18 years who were admitted from January 2005 to December 2009 from one million random samples in the National Health Insurance Research Database of Taiwan.
Research results
This study showed that choledocholithiasis patients who underwent further CCY after ES/EPBD can reduce subsequent cholangiocarcinoma risk from 2.35% to 1%. And the subsequent cholangiocarcinoma risks had a good correlation with RBEs in our study. Choledocholithiasis patients who have undergone an ES/EPBD intervention without further CCY had a 25–26-fold higher subsequent cholangiocarcinoma risk than the normal population.
Research conclusions
Further CCY in ES/EPBD patients decreases subsequent cholangiocarcinoma risk by reducing RBEs.
Research perspectives
This study not only showed different subsequent cholangiocarcinoma risks in the ES/EPBD, ES/EPBD and CCY, and no intervention groups of symptomatic choledocholithiasis patients, but also the significant relationship between the incidence of RBEs and that of subsequent cholangiocarcinoma.
