Endoscopic retrieval of a migrated pancreatic stent under direct pancreatoscopy by use of a “snare over in-stent wire guide” method

SpyGlass DS system‐assisted retrieval of proximally migrated pancreatic duct stent in a patient with chronic pancreatitis

“…Direct visualization by SpyGlass also helped in the cannulation of the guidewire to ensure that the end of the stent had been reached before retrieval. We have compiled the published cases so far of SpyGlass‐assisted removal of migrated stent, including in the pancreas and other locations, from PubMed in Table 1 8–13 . To our knowledge, this is the first case of retrieval and repositioning of a 7 Fr PD stent using the SpyGlass DS system, which has a high success rate and fewer complications due to direct visualization and is cost effective.…”

Treatment of a proximally migrated plastic stent in a case of refractory distal biliary stricture

“…1 Although endoscopic retrieval could be an effective method of addressing migrated stents, surgery may be required if endoscopic retrieval is unsuccessful, especially in benign diseases. [2][3][4] A 34-year-old man had experienced severe acute pancreatitis after excessive drinking 1 year earlier.…”

Use of intraductal cholangioscopy devices to retrieve migrated pancreatic stents

“…Stent retrieval remains challenging owing to characteristically small pancreatic duct diameters, strictures, tortuous distal pancreatic duct course, stent location proximal to the genu, and small-caliber stents. Novel retrieval techniques for proximally migrated pancreatic stents have included pancreatoscopy to achieve guidewire cannulation of the stent lumen [2,3] or facilitate retrieval using SpyByte forceps (Boston Scientific, Marlborough, Massachusetts, USA), though duct diameter must be large enough to accommodate a SpyScope for such techniques. For ducts of small or normal diameter, proximally migrated stents can be cannulated with a guidewire, over which mini-snares can be passed to retrieve the stent [4, 5].…”
