A 76 year old female came to the outpatient clinic with a chief complaint of a string-like appearing substance in her stool. A fecalysis was done at our institution which showed the presence of eggs of Diphyllobothrium nihonkaiense. During hospitalization, a nasal endoscope was inserted into the descending duodenum followed by injection of 400 ml of gastrografin into the intestinal tract through the biopsy port; all were done under fluoroscopy. Expulsion of the worms was confirmed thirty minutes after gastrogafin injection. To date, this is the first reporting of Diphyllobothrium nihonkaiense treatment using nasal endoscopic gastrografin injection along with supplemental information from previous literatures.
