Drill Crush Technique: A Novel Lithotripsy Method for Giant Bile Duct Stone Removal in a Patient With Surgically Altered Anatomy (With Video).

With accompanying video, Koga and colleagues describe the drill crush technique, a novel endoscopic method for removing large impacted bile duct stones in patients with surgically altered anatomy. Using a screw-type drill dilator, this stepwise approach enables safe and effective lithotripsy and offers a minimally invasive alternative when conventional methods fail.
