Endoscopic Ultrasonographic Findings of Two Cases of Parasitic Eosinophilic Granuloma in the Stomach / 대한소화기내시경학회지

ABSTRACT

Anisakiasis is a disease of the alimentary tract caused by nematode larva belonging to the subfamily Anisakinae. It is possible for Anisakis larva to be transmitted to man through eating raw sea fish that is preferred by Korean people. The clinical symptoms are characterized by severe cramping abdominal pain, nausea, vomiting, diarrhea, tarry stool, and epigastric fullness. The endoscopic examination has played a important role in the diagnosis of anisakiasis. However, gastric anisakiasis is undetected due to unspecific symptom and delayed endoscopy. Endoscopic ultrasonography is probably the choice of investigative tool for the evaluation of submucosal mass. However distinctive feature of parasitic infectation presenting an submucosal tumor has not been reported. Recently, we experienced two cases of gastric anisakiasis. We found gastric submucosal tumors by endoscopy, differentiated them by endoscopic ultrasonography and treated by endoscopic submucosal resection.
