Endoscopic ultrasonography-guided endoscopic treatment of pancreatic pseudocysts and walled-off necrosis: New technical developments

Figure 1 Endoscopic ultrasonography guided placement of a transgastric metal stent allows endoscopic access into the necrotic cavity for endoscopic debridement. A: Gastric end of the covered transmural stent; B: Endoscopic view within the stent showing blocking necrotic material; C: Endoscopic view of the necrotic cavity after passage of the endoscope through the metal stent (two weeks after flushing via a nasocystic tube).
