This 34 year old female resident of rural China presented with nausea and vomiting, vague abdominal pain and fever. An upper endoscopy was performed in Beijing. As the endoscope is advanced to the second portion of the duodenum, a live Ascaris was encountered. Ascaris infections occur worldwide, with current estimates suggesting that 1.4 billion people may be infected with this parasite. The roundworm is retrieved using a basket. Once the worm is secured in the basket, both worm and endoscope were removed from the patient. Notice here the length of the organism, about 20cm in total, and the continued movement.
