Core Tip
Core tip: Adequate management of plastic stents for choledocholithiasis was evaluated. Stent exchange was carried out at every 6 mo (Group A), every 12 mo (Group B) or on demand (Group C). The stent patency rates were 91.4% for Group A and 88.6% for Group B, respectively. In Group C, median stent patency was 16.3 mo, and stent exchange was required in 70.6% of patients. There was no biliary-related mortality. Although 12 mo is considered a safe interval for plastic stent exchange, long-term biliary stenting can be an acceptable option for selected patients who are medically unfit for further invasive procedures.
