Many transmural endoscopic devices have been developed for various different procedures; however, few options exist to endoscopically process these indwelling devices once they have been positioned. Here, we introduce a novel technique that allows indwelling devices to be cut endoscopically using a combination of an endoscopic retrograde cholangiopancreatography (ERCP) lithotripter handle and a guidewire, as illustrated in these two patients.
The procedure is performed as follows: (i) an ERCP guidewire (VisiGlide 0.025 inch; Olympus, Tokyo, Japan) is inserted through a therapeutic endoscope (GIF-1T240; Olympus) and is looped around the indwelling device using a biopsy forceps (FB-45Q-1; Olympus) ([Fig. 1 a]); (ii) a lithotripter cable (Conquest TTCL-1; Cook Japan Inc., Tokyo, Japan) is inserted over the guidewire up to the indwelling device ([Fig. 1 b]); (iii) the guidewire and the cable are connected to the lithotripter handle (Soehendra; Cook Japan Inc.) ([Fig. 1 c]); (iv) the guidewire is reeled in using the handle, until the tightened loop of the guidewire cuts through the indwelling device ([Video 1]).

Quality:
The first patient was a 90-year-old woman who was admitted to our department because her percutaneous endoscopic gastrostomy (PEG) tube had migrated into her duodenum ([Fig. 2]). No conventional endoscopic devices were able to cut the PEG tube; however, using our technique, the tube was successfully cut into two pieces. Both pieces were then removed endoscopically without any complications ([Fig. 3]).

The second patient was a 60-year-old man who was referred to our department with postoperative pancreatic pseudocysts. After the pseudocysts had shrunk remarkably with effective endoscopic ultrasound (EUS)-guided drainage, the external drain was successfully converted into an internal drain by cutting the tube using our technique ([Video 2]).
Quality:
Our technique has some advantages over previously reported endoscopic scissor forceps [1] [2]. Our method is highly capable of cutting hard materials because the lithotripter system used was originally designed to fracture large common bile duct stones. The technique can be easily and immediately introduced because all the required devices are commercially available.
