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.
