Background:
Endoscopic drainage of pancreatic pseudocysts and abscesses has been shown to be an effective treatment modality. A major determinant for successful cyst resolution is the insertion of multiple endoprostheses and/or placement of a nasocystic drain, which require repeated entries of a catheter into the pseudocyst to reintroduce the guidewire.
Objective:
We describe a novel and easy technique to prevent the need for repeated access into the pseudocyst, thereby facilitating the placement of multiple endoprostheses by using a commercially available guiding system for stent introduction.
Design:
Case series.
Setting:
Academic Medical Center, The Netherlands.
Patients:
Eight consecutive patients with symptomatic pancreatic pseudocysts after acute pancreatitis.
Interventions:
Intracystic wire exchange for the insertion of multiple stents in endoscopic treatment of pancreatic pseudocysts by using an echoendoscope.
Main Outcome Measurements:
Feasibility of intracystic wire exchange and complications.
Results:
No guidewire access to the pseudocyst was lost. The procedure was well tolerated by the patients. Complete pseudocyst resolution was established in all patients.
Conclusions:
The endoscopic appliance of multiple stents becomes easier when using intracystic wire exchange for transgastric pancreatic pseudocyst drainage.
