Endoscopic transgastric drainage of a gastric wall abscess after endoscopic submucosal dissection

Figure 3 Endoscopic transgastric drainage for a gastric wall abscess. A: Gastroscopy revealed a smooth, elevated lesion at the greater curvature of the upper body on the oral side of the post-endoscopic submucosal dissection ulcer; B: A gastric fistula was found on the edge of the post-endoscopic submucosal dissection ulcer. The fistula is indicated by an arrow; C: An endoscopic retrograde cholangiopancreatography-catheter was inserted through the fistula into the abscess; D: A plastic stent placement for the internal fistula and a nasocystic catheter for the external fistula were successfully inserted into the abscess.
