Background
Endoscopic drainage of pancreatic fluid collections (PFC) is performed with increasing frequency. A variety of techniques for performing transmural entry have been described. However, data are lacking on the technical success and safety of transmural entry using a single technique. The authors describe the largest experience in transmural entry of PFCs without endoscopic ultrasound (EUS) guidance using a dedicated aspiration needle.
Methods
All patients who underwent endoscopic transmural drainage of PFC from October 1998 to May 2006 were identified from the endoscopy database. Data were abstracted from the endoscopic procedure report and the patient records then placed in a JMP drive. All drainages were performed without EUS guidance after visualization of an obvious intraluminal bulge using a dedicated large-bore aspiration needle. The transmural tract into the PFC was dilated using a balloon with a diameter of 6 to 20 mm followed by subsequent placement of one or two 10-Fr double pigtail stents with or without nasocystic irrigation tubes. Successful entry was defined as entry allowing for the placement of stents.

• Pseudocyst (acute pancreatitis) | • 25 |
• Pseudocyst (chronic pancreatitis) | • 19 |
• Pancreatic abscess | • 5 |
Size of PFC (cm): median (range) | 11 (3–23) |

Conclusion
Endoscopic transmural drainage of pancreatic fluid collections can be performed safely and effectively via the Seldinger technique without endoscopic ultrasound guidance. The study data will allow sample size calculations to be made if direct comparisons with this technique and others are undertaken.
