The esophagus after endoscopic injection sclerotherapy: acute and chronic changes.

The changes seen on radiographs of the esophagus following endoscopic injection sclerotherapy (EIS) for varices are described and illustrated. In the early period (within 30 days) after EIS, the spectrum of changes includes mucosal ulceration, luminal narrowing, intramural defects, sinuses, fistulae, esophageal dissection, and perforation. In the late period (after 30 days), the spectrum includes strictures, irregular contour, mural defects, esophageal dysmotility, and luminal obstruction. Familiarity with these radiographic features will aid in proper interpretation of esophagograms following EIS for esophageal varices.
