Procedural technique shows successful treatment of bile duct stones in a patient after distal gastrectomy, suggesting improved efficiency.
Using an accompanying video, Sakurai et al. described a peroral direct cholangioscopy (PDCS) technique using a double-balloon enteroscope (DBE) that successfully treated bile duct stones after distal gastrectomy with Billroth II reconstruction (B-II gastrectomy), enabling precise device manipulation, wider device selection, and shorter procedure time by eliminating scope exchange.
