Abstract:
Tract dilation prior to stent placement is an important step in endoscopic ultrasound-guided hepaticogastrostomy. Mukai and colleagues describe their use of a novel catheter with a longer balloon, which enables one-step tract dilation of the gastric wall, liver parenchyma, and bile duct wall, shortening the procedure and reducing bile leakage.
