Abstract:
A new mechanical puncture video echoendoscope (GF-UMD-240P 270 degrees image field parallel to the endoscope axis) has been used for puncture and drainage of a symptomatic pancreatic pseudocyst. It is equipped with a 2.8 mm working channel and an elevator allowing single step drainage with passage of a 7F nasocystic catheter.
