Figure 18. Esophageal stricture caused by endoscopic sclerotherapy. Single-contrast esophagogram shows a long, irregular stricture in the distal esophagus (straight white arrows) that resulted from scarring caused by prior endoscopic sclerotherapy for esophageal varices. Note also the flat ulcer in the region of the stricture (curved white arrow). Black arrows indicate a transjugular intrahepatic portosystemic shunt.
