The self-disengaging biliary stent-making and fixing procedure. a–c A 6-Fr double J tube was trimmed to approximately 15 cm in length. A terminal coil was fashioned at one end using 4-0 coated Vicryl® (polyglactin 910) sutures; d Following stone removal, a guidewire was first positioned through the working channel of the choledochoscope under direct endoscopic visualization. The choledochoscope was then carefully withdrawn while maintaining stable guidewire access. Finally, the self-disengaging stent was advanced over the guidewire into position; e Confirm the stent is positioned under choledochoscopy, passing through the papilla into the duodenum; f Perform the primary closure of the CBD and temporarily fix the stent by looping the coil at the end of the stent into the suture line.
