Proximal migration of a pancreatic duct stent: endoscopic retrieval using interventional cardiology accessories

Use of a small-caliber angioplasty balloon for the management of an impassable choledochocholedochal anastomotic biliary stricture

“…These balloons, which are not standard endoscopic retrograde cholangiopancreatography accessories and are not available from ERC vendors, were first described for endoscopic use for the removal of a small-caliber migrated pancreatic stent. 2 In only one other report were they used for dilation of an otherwise impassable biliary stricture in the setting of primary sclerosing cholangitis. 3 To our knowledge, this has not been described specifically for anastomotic biliary strictures in the posttransplant setting.…”

Endoscopic treatment of intraductal pancreatic stent fragmentation

“…[14][15][16] Baron et al also described the retrieval of a migrated stent with the use of tools that are used in interventional cardiology. 17 We distinguish three techniques for retrieval of migrated or broken stent: direct with accessories described above and indirect with high-pressure balloon or guidewire cannulation of the stent lumen. 9,14,15 Figure 1 A 45-year-old patient with a stent broken in two places.…”

Dilation of high-grade pancreatic and biliary ductal strictures with small-caliber angioplasty balloons

“…Baron et al 6 reported the novel use of an angioplasty balloon to extract a migrated pancreatic stent. However, that device required use of a 0.014-inch guidewire with a special extension and lacked the necessary rigidity for passage through tight strictures.…”
