Endoscopic cystgastrostomy: role of endoscopic ultrasonography.

Abstract

We report a case of successful endoscopic cystgastrostomy guided by endoscopic ultrasound after an unsuccessful attempt of "blind" drainage. Endoscopic drainage of pseudocysts without endoscopic ultrasonography is an appropriate initial approach by experienced endoscopists in carefully selected patients. In cases in which an intraluminal impression by the pseudocyst is not well visualized, or the conventional approach has not established drainage, endoscopic ultrasound provides excellent localization for the therapeutic maneuver.
