EUS-guided one-step drainage of pancreatic pseudocysts: experience in 3 patients.
BACKGROUND
EUS-guided drainage has been recognized as a nonsurgical treatment for pancreatic pseudocysts. Bleeding at the puncture site is a known complication of this procedure. This is a report of the use of new equipment for one-step drainage without the use of an electrosurgical needle.


METHODS
EUS-guided cystoenterostomy was performed in 3 patients. The mean size of the pseudocysts was 8 cm (head = 1, body = 2). A needle and drainage tube were inserted in a one-step procedure into the cyst through the accessory channel of an echoendoscope under EUS. The drainage tube was released immediately after insertion.


METHODS
All 3 patients were treated successfully without complication. A drainage tube was inserted through the duodenal bulb (n = l) and the body of the stomach (n = 2). The drain was removed after 1 month in all patients. Two of the 3 drains were obstructed by sludge. One pseudocyst recurrence was observed at a mean follow-up of 3.6 months (range 2-6 months).


CONCLUSIONS
The EUS-guided one-step system is simple to use and suitable for drainage of pancreatic pseudocysts. It appears to minimize the risk of hemorrhage.
