Abstract:
A novel biliary drainage system consisting of an integrated biliary stent and nasobiliary drainage catheter system is expected to be clinically useful. However, Yamamoto and colleagues report two cases of acute cholecystitis after use of the system, suggesting that there are risks of adverse events associated with its unique design.
