Endoscopic diagnosis of Fasciolopsis buski: Revisited (with video)

Fasciolopsis buski is the largest fluke parasitizing the human small intestine. F. buski infections are not uncommon in Southeast Asia. The risk factors of F. buski infection mainly include eating of raw aquatic crops and infected snails. Most infections are asymptomatic. Heavy infection can be fatal as the flukes cause extensive intestinal inflammation, intestinal perforation, small bowel stricture, ulceration, hemorrhage, and abscess formation. Endoscopic diagnosis of this parasite has been described in a few case reports. Here, we describe and illustrate the endoscopic removal of F. buski from the stomach and duodenum.
