A proximally migrated pancreatic stent is usually removed using a basket, balloon, snare or forceps [1] [2] [3]. The lasso technique [4] and its variation [5] have been described. However, no method for retrieval of a migrated pancreatic stent has been established. We retrieved a disrupted pancreatic stent using a nasopancreatic drainage tube (NPDT).
A 45-year-old man underwent pancreatic stent placement for chronic pancreatitis. The stent became disrupted 4 months after placement ([Fig. 1]).
The distal part of the stent was removed; however, the proximal part could not be retrieved and remained in the body of the main pancreatic duct (MPD), despite attempts at removal using biopsy forceps, basket, balloon and a Soehendra stent retriever. These attempts led to the migration of the pancreatic stent upstream. So, a guide wire was inserted through the lumen of the stent ([Fig. 2]), and then a 5-Fr NPDT was inserted over the wire until it extended beyond the stent.
As the NPDT was gently pulled out, the stent moved with it toward the duodenum ([Fig. 3]).
The first flap of the NPDT was stuck into a side hole of the pancreatic stent, and the second flap was resting just before the distal end of the stent ([Fig. 4]).
After removal, the flaps were seen to be nearly at right angles ([Fig. 5]).
Removal of a migrated pancreatic stent using a basket or forceps is sometimes difficult. If the angle of the device in relation to the stent is not appropriate, the device will slip, cannot grasp the stent or will push it upstream. Inserting a 5-Fr NPDT is easy because it is slender and can be inserted over a guide wire. Grasping the stent is unnecessary. When a NPDT flap sticks into a side hole of the stent, removal will be possible in cases without stricture or a stone downstream of the main pancreatic duct.
Using a NPDT is one effective option for retrieval of a proximally migrated or disrupted pancreatic stent in the main pancreatic duct.
