Nonfluoroscopic endoscopic ultrasound-guided transmural drainage of pseudocysts: A pictorial technical review.

Pancreatic pseudocysts (PP) are one of the important local complications of pancreatitis and can be treated by surgical, laparoscopic, percutaneous, or endoscopic methods. The endoscopic methods of drainage include transpapillary or transmural drainage or a combination of these two routes. The transmural drainage can be done using conventional duodenoscope without endoscopic ultrasound (EUS) guidance or under EUS guidance. The EUS-guided transmural drainage of PP is done under EUS and fluoroscopic guidance. We have earlier reported nonfluoroscopic EUS-guided transmural drainage of walled-off pancreatic necrosis. In this pictorial technical review, we will discuss in detail this method of nonfluoroscopic EUS-guided drainage of PP.
