Answer
The structure was found in the GV after EIS treatment. We believe that the small intestine obstruction resulted from a part of the polymer falling out of the GV after EIS treatment. Bowel obstruction was treated conservatively and, the polymer was excreted naturally from the intestine. GV, detected using endoscopy, are found in 20% of patients with cirrhosis portal hypertension. Treatment for GV using Histoacryl® was first reported in 19861, and it became the first-line management option of GV due to its rapid hardening quality in the blood2. After sclerotherapy, solidified Histoacryl® may be frequently extruded as a polymer into the lumen2. There are no previous reports of bowel obstruction caused by the polymer after EIS using Histoacryl®; however, it is possible that the extruded polymer caused the obstruction.
